I needed new windows and new sliding glass doors. The previous owners of our appartment had put in the cheapest possible units with the cheapest possible labor. With regards to the heating of our home, the windows were no better than screens. I reached out, looking for windows and installers. I had a few people come in and estimate the job. None of them impressed me until Greg from Windows on Washington came over. He walked me through several options and explained how the windows they used were manufactured and why. Windows on Washington got the job. My windows and my doors were being manufactured. So they sent out a wonderful gentleman to get the final accurate measurements. Great guy. After that, communication was wonderful as were were assessed of the stage we were in. This included when we got the email and calls explaining that, since we were on a higher floor, they needed to bring in some equipment to lift the new doors up to our balcony. No surprises. Installation day was amazing as Joon and his team came in, got everything into place, and cleaned up the areas to better than when they got here. Joon then went over the features on our windows and even explained how we get to and clean the outsides of the glass. Wonderful man and amazing team. Since then, we have gotten copies of our warranty and the guarantees. And the company has reached out twice to ask if we have any questions and to ensure that we are happy with our windows. We are. We are very happy with our windows. Almost as happy as we are with the people who got them into our home. read more

Windows on Washington just installed 23 Okna windows in our home. From the initial visit to the finish, they did an excellent job, and they came in ahead of schedule. I recommend them highly. Roger Pilon Bethesda, MD read more

New door Insulation good and installation It is very expensive. Over 5000 for a kitchen door . Not what I wanted to spend . Door is perfect but ... Front office not very friendly . I experienced them as demanding for Payment. I was happy to pay for it, but there seems to be some sort of glitch with the front office. read more

The installation team was every bit as fantastic as Eric said they would be. Which was largely the reason we chose WoW! After all, it is our home and we want to make certain we get the best products, expert craftsmanship, and clean installation that is issue free. The crew was on time, professional, communicated process well and worked hard to do a good job the correct way. The crew lead was Jeff and he was super professional and came across as very honest. They cleaned throughout the entire process, installed all products that fit perfectly with expert skills. They did a thorough job at insulation replacement windows and the finish caulk job was immaculate. The look from the curb is stunning and I can notice how well the windows are performing as it seems the air is running less in just the week we had them. We love our new Okna 800 windows and Eric and team killed it! read more

Workers arrived early, were efficient, left the work area spotless and above all were very pleasant. The new windows are beautiful!

Windows on Washington gave me a fair price from the start. Becky Flynn in the office helped me with the contract she was extremely helpful and pleasant, also efficient. She provided a detailed estimate and changed details that we needed changing. Tanya West in billing was very efficient and easy to understand and the setup is professional. Everyone in the business tend to be more honest and treat customers with respect. We live in Pasadena, I was apprehensive the company would not come this far from Virginia, but we had no problem with any employee. They were so efficient the crew showed up exactually the time scheduled. Joon Kim crew had the windows off in an hour, they worked steady until the windows were finished. They protected the floors at each window. Extremely positive experience from start to finish. Very highly recommend. read more

We absolutely love our new wall of windows and door. The craftsmanship looks that of fine furniture. We will be able to use our patio year around now. The cost was in fact our lowest bid received, but the communication, attention and professionalism of this company won us over. Everyone we dealt with made sure we happy and worked hard for perfection!!! We are so glad we invested in WOW! read more

I'm reviewing WoW for the second time. The first review was for their replacement windows, which was an absolutely flawless experience! Their windows are tops & have performed perfectly ever since. I continue to highly recommend them for replacement windows. Because of our superb experience the first time 'round we contracted with them via their most excellent salesman Brandon Shonebarger for a new entry door and storm door. This time 'round there were problems from the installation on. I won't give a blow by blow here as it's too long & too much. Suffice it to say that the repairs took as long to complete as the initial order time line & required multiple trips & two different repair people!! I need to give a shout out to the second repair man - Plamen - he was actually the original installer until the main installer guy showed up & basically took over). Plamen spent close to 3 hours making the needed adjustments & repairs to make sure that the entry door & storm door worked properly. He patiently explained why one of the multiple issues could not be solved (due to physics, but which I think the industry could easily solve). Plamen worked his butt off, was professional, courteous, conscientious, & the best part of the whole experience. I cannot recommend WoW for replacement entry doors & storm doors, with the same level of enthusiasm that I can for replacement windows. That's too bad. Dealing with Tanya & Gretchen at the office was also a pleasure. Thank you ladies! In the end I was able to work everything out with the owner Eric Novotny to my satisfaction. read more

WoW recently installed 12 Okna windows and a glass sliding door for my townhouse. We had an excellent experience working with John Y. for the estimates. He is very knowledgeable and helpful. Joon K. and his crew were very professional and efficient. They all did a fantastic and meticulous job on the installation. We love our new, top-quality windows and door, and highly recommend WoW. read more

Final results were even better than I expected. Project included new windows throughout included replacing rotting window sills, new exterior doors, and new siding in beautiful colors that I actually chose. I had accessed the Alside siding website for an AI image to provide to the HOA while seeking approval and that AI generated image looked better than the original (thus was approved by the HOA) but the actual finished project looked better still and exceeded my expectations. I marvel at how much I love the appearance of my house, also love that all the doors lock properly and the sliding glass back door actually slides more smoothly than ever. The windows seem to be much better insulated too. Harbor Blue siding was chosen to replace the Colonial Ivory. Black shutters to replace the green. Red door replaced the front door which also had been green. Bright white trim including gutters/downspouts and soffits. The front door had sidelights which I decided to keep and I had thought the glass would be frosted but it was not (probably my misunderstanding) this was something I remedied myself with a window film from a home improvement store (same as I had done over a decade prior on the old ones). Gone is the damaged boring color siding, rotted wood trim around the poorly insulated windows and doors (which looked their age of 31 years). The new exterior makes the house look brand new, we have received a lot of compliments from both neighbors and friends. read more

Great service and value. The quality of the windows is in the top tier of providers. The installation went smoothly and with quickness without compromising quality. We had 12 windows installed of many shapes and sizes. All of them are excellent. read more

Can't say enough good about Windows on Washington. Eric is extremely knowledgeable, honest, helpful and kind. His expertise and input helped us to make an informed decision about our window replacement project for our condo that otherwise, would have been difficult to figure out. If you are looking for quality, integrity and expertise in a window company that puts people before profit, look no further. Many thanks Eric! read more

I am absolutely thrilled with our windows from WOW. From the initial consultation to the window measurements, I was impressed by the customer service and communication. I live in a condo and they understood the HOA rules and requesting variance for my frosted bathroom windows. I was advised of the window delivery timeframe given the supply chain issues and the windows were actually delivered at the shorter end of the timeframe. The team was wonderful about keeping me up to date on the expected delivery, what to expect during installation etc. The installation of my 12 new windows took about 8 hours and they were very professional and left my home in clean condition. I love my windows so much, I did not know one could love their windows before hah! read more

Very good interaction, product, and relatively competive pricing. Not chosen only due to a comparable lower price. Recommended for estimation. read more

Really recommend Windows On Washington. They help install a new roof on my townhouse, were great to work with and the roof is great.

Every part of my experience with Windows on Washington (WoW) was excellent. From the time I contacted them for information, to setting up my initial appointment to get an estimate, to ordering, installation and customer service (more on this in a minute) were simply second to none. Based on other reviews, I knew WoW was not the cheapest place for windows but I also read of the great quality products, installation and customer service. Let me say that their pricing is comparable and more than fair, and their products, service and installation are simply outstanding. I love my new windows! This is one of the very few places that vastly exceeded my expectations. Don't get the wrong impression that everything went perfectly. It did not. Based on the fact that some of my windows vary slightly in size, the manufacturer sent a couple of windows with the incorrect handles. This is where WoW stepped up and demonstrated why they have the best customer service. They worked with the manufacturer to correct the issue and made it 100% right. They worked as my advocate each step of the way and made sure I was completely happy before calling the job complete. There was no effort required on my part as WoW took care of everything. I only wish every business were as ethical and service oriented. As for the windows themselves, they are top quality and perfectly installed. And I do mean perfectly! My house looks better and is quieter and more comfortable. The windows are so solid that they feel and sound like mini bank vault doors. Cosmetically, the area around the windows (inside and out) looks and is better than before. There are no marks, scratches, dings, leaks, air gaps, nothing. We have had our windows for a couple of months now and dealt with rain, snow and very high winds (40 mph+ gusts). From the inside of my house, you cannot tell what the weather is outside. I give Windows on Washington my highest recommendation and suggest you give them a call if you are considering new windows! read more

After speaking to Lee on the phone (who was delightful) Shayne was sent out to give me a quote. He took his time (but not 4.5 hours like the guy the day before him), and I felt like he was really thoughtful in his suggestions, and had an artistic mind. We might not do the windows til next year, and they weren't the cheapest quote by far, but I really loved the vibe and feeling this company gave me, with a no pressure sales pitch. read more

WOW - pun intended! We are very pleased with Windows on Washington's communication, products, team, and service. Joon was our project manager and he did a great job making sure everything was completed to perfection. His team was quick and professional. Look no further, this is your go-to for new windows! It's been 3 years since we've lived in this house and the 1960's windows were painted shut. Our cats might be enjoying this more than us! ;) Thanks Windows on Washington and especially Joon for making this a pleasant experience. read more

I had a mixed experience with WoW, and this review is actually averaging my windows replacement project (5 star experience) and an attempted skylights project (1 star). For windows: like others I had a good experience with Brian (sales) and Joon (installation). Prices for OKNA windows are not cheap, and like others I had to wait a long time for the windows. But, once they came in, the installation went quickly and smoothly. They did bring the wrong sized screens, and didn't seem to notice until I brought it up, but the correct full screens were ordered and installed in a follow-up visit a few weeks later. For skylights: this experience was a bit of a disaster, and felt like I was dealing with a different, much less competent company. (WoW seems to have different teams for windows vs. roofing projects.) Many months of delays, sporadic communication, and ultimately the installation crew arrived with the wrong type of skylights. Jim Sigmund, the coordinator, said that when they came to measure the skylights, they noted the wrong type of skylight, and no one caught it. 6 months wasted. WoW did issue a refund relatively quickly after that, though. I want to be fair to WoW--I think the windows are good quality. However, I would not recommend getting skylights from them. read more

I like to take my time and wait before posting any review, particularly with home improvement projects. My experience with WOW was outstanding from start to finish. From Jay H. giving me an honest and transparant estimate, as well as a realistic time from for when the door would actually arrive. I was having my front door and frame replaced. Throughout the whole process they were extremely communicative and kept me appraised of every update. The day of the installation everything went very smoothly, from the crew showing up on time to their professionalism. They did their very best to minimize the mess and noise while still working quickly. They did a fantastic job cleaning up and disposing of the materials as well. I wanted to wait to write my review, the door was installed several months ago, until I was sure there were no issues. So far everything checks out and I am very happy with how the door looks, operates, and feels. I highly reccomend WOW and plan on utilizing them for when I replace my windows as well. read more

For starters and for those who aren't aware of Eric, he is the owner of WoW and is one of the key contributors for the replacement window forum, the largest forum in the US for contractors and consumers to discuss window needs. When I started my process of digging up information on windows, I had no idea where to start, who to go to, and what to do. This process was atrociously confusing even for a savvy consumer myself, especially where there is so much technical knowledge involved (e.g., U-factor, solar heat gain coefficient, virgin vinyl, etc.). Who and where would you go to get this information? For myself, the replacement window forum was one of the most important places where I was able to learn and get reaffirmation on key steps that I needed to understand throughout the buying and installation process. Eric and several other contributing members in the forum are some of the best experts in the nation and their honesty and transparency allow you to really help you understand the nuts and bolts of everything you need to know about windows. Long story short, they recommend fantastic products (well the best) for your money (such as Okna if you are going for vinyl). It's more expensive than your builder grade windows but digging through the forum, you'll learn why it's so important to buy good windows and what you should really look for. You don't want to go too cheap (e.g., HD or Lowe's) nor do you want to go too expensive (E.g., renewal by anderson which is largely a marketing gimmick). Where Eric and his team really shine are when you run into your situation specific problems during the entire window buying and install process. Trust me when I say this. You are going to run into SOME kind of problem and that answer will not readily "googleable". In this day and age where order wait times are more than 6 months because of supply chain issues and factories are screwing up left and right with orders, and contractors are messing up, you don't want to be left in the cold without a way to fix the problem. Moreover, you want honest contractors who can help you through. Once again, I reiterate this. You are MOST likely (if not almost guaranteed) to run into issues. If you think window buying experience is like an amazon one-click purchase you are so dead wrong. No matter how much Eric or any business owner tries to prevent issues, something is bound to go wrong. The question is, do you want someone who is honest, knowledgable, and willing to fix the issue on your side or do you want some slimeball who tries to avoid taking responsibility and gives you massive headache? With a 5 digit dollar puchase, you don't want to take this kind of risk and go with someone who is knowledgable and trustworthy like Eric. Normally, I would cringe when I see a few 1-3 star reviews but I wouldn't be bothered by them for WoW. They are overall at 4.5 star or more and in this day and age, I have yet to see any window install go correctly for the many folks who had their window installs done since the pandemic began. The most important factor is whether your contractor is trustworthy, knowledgable, and is willing to fix the issue. If you have any more questions about Eric, you should go on a search engine and look for his replacement window forum (not linking due to yelp rules). If you spend some time (which you should since it's a lot of money), you'll know what kind of a great person he is and what reputation he has built over the years. read more

I needed to replace eight 20-year old windows on the front of my house and received two quotes that were close in price. WoW was the more affordable option, had great reviews, and provided a very knowledgeable consultant to work with. I began the process in May 2021, and final installation was completed in early October due long delays in the manufacture process I'm sure we're all familiar with by now. The installation crew arrived on the early side of the 1-hour window I was given, which I appreciated. The crew was polite, professional, and most of all very efficient. In just over 3 hours the crew had removed all my old windows, installed the new ones and they did a great job of cleaning up after themselves as well. Special thanks go out to Zach, Becky, and Joon and the crew for taking the time to explain things to me where needed, and for being easy to work with. If you are looking to support a local company with great prices, a great warranty, and outstanding service I highly recommend Windows on Washington. read more

Windows on Washington was professional and responsive. The consultant came to look at a window that had been stuck for over a year and that we could get back in the frame. The consultant was able to fix the window during the consultation for no charge. Would recommend and will consider them if we decide to replace our windows. read more

The team at Windows On Washington is absolutely awesome! I found them professional, very courteous, and experts in their trade. One representative measured the exact dimensions of each window before even scheduling the work and ensured to explain the process in detail. The installation team was very respectful of my white carpet - used drop-cloths everywhere, and answered any questions I had. Eric, the owner of the company came by during the windows installation process of the new windows, to ensure my satisfaction. He also explained many more aspects of the windows themselves, their fabrication process, as well as the installation process I didn't even know to ask. I was very impressed by the team's meticulous attention to detail on all efforts, including the clean-up afterwards. They even vacuumed the common hallway for the building before leaving. I am very happy with my new windows and highly recommend Windows On Washington for their quality work and very competitive pricing. Sincerely, Lee V. read more

Couldn't be more pleased with the experience from sale to installation. I got 3-4 quotes before deciding on WoW, Zach the sales person actually listened to my requirements and was very informative on options and was on hand to answer any questions I had from sale to install and very quick to respond. The installation team were on time, performed the job in the allotted timeframe given, were respectful, courteous and above all they did a great job. Even as they were leaving Yong (hope i spelled that correctly) was checking all caulking once again. They did a great job showing me how the windows worked also. I am thrilled with my new windows, and the price was very competitive also, allowing me to break the project into manageable phases and not trying to get me to complete the entire house in one go. My only frustration (although I understand the reasons) was the time from order to install based on backlog due to inclement weather, but you can't control the weather! Go with this company, you won't be disappointed! read more

I hope this 1000+ word review saves you pain. Because after negotiating with 12+ DC area window companies for months, Windows on Washington was completely painless. Let me tell you why: Here's what was important to me: **I wanted very insulating windows. I had old 1950's metal windows that leaked so much air, ice formed on the inside during the winter. We also had been scarred by some newer Andersen double hung windows that leaked air. **I wanted a very high level of installation quality. We already had some windows replaced a couple of years ago, and the windows clearly were leaking air around them. (poor caulk job) ** I wanted a guarantee that any problems would be taken care of. I was willing to pay a little bit more, to know that I could just call someone and they would take care of ANY problems, in an honest and swift manner. I didn't want to deal with the manufacturers. Deciding on Window Installers In the DC area there were 3-4 kinds of installers that kept coming up: National Players - Home Depot, Andersen, Thompson Local Installers - These are larger companies with multiple crews. This is what they do for a living. They tend to have preferred brands, so you'll have to take their advice with a grain of salt Roofing/Siding/Window teams - I liked a number of the companies I met, but they failed me in two areas: 1) When I asked them what percent of their jobs were windows, they often said less than half. I'm looking for teams that are well versed in window installation. I understand that doing 10 a year means your an expert. But if you're not doing 50 a year, then you might be a little rusty, or sloppy. 2) A lot of times these teams didn't have window experts (related to the above). They said their crews did it all, which made me concerned with their level of expertise Home Improvement - These are truly jack of all trades and do everything from countertops to doors to bathrooms to windows! I'm sure they could of done the job well, but they rarely offered me warranties on labor beyond 2 years and my biggest concern was that if something didn't go well, they would be painful to deal with since they wouldn't engage with the window manufacturer directly. As I mentioned earlier, I was looking for more white-glove service, so I definitely wanted a contractor that would handle any issues (condensation, cracked vinyl, leaky air, etc) I ended up with two front-runners: Quality Window and Door - I liked them a lot. Salesperson was honest, although a little slow at turning around revisions. Pricing was expensive, but they seemed like a high-quality shop. In the end, I just didn't trust the windows they were selling. Every time I read reviews on windows the salesperson suggested, I found lots of people with issues in the DC area with that brand and I ultimately hesitated. I also didn't find his suggestions on brands helpful. There was no "here are the Pros and here are the Cons". It was just "Here's what I think you should do." I feel bad. They spent quite a bit of time with me, but in the end, I didn't feel that I would end up with a high quality window. I decided on WINDOWS ON WASHINGTON? Why? They definitely weren't the cheapest, but they -Sold OKNAS (an amazing window, the air infiltration rate is out of this world, which means NO WINTER DRAFTS, the sun reflection is perfect and the locking system is incredibly smooth) -Offered a lifetime warranty on Windows and Labor -Did not have pushy sales people and did not try to upsell me -Were reasonable about considering other offers -Were confident and articulate in how they would deal with problems that might arise during and after the installation (again, I wanted full-service here) -Wanted to make sure I was happy and it felt like they had a reputation they wanted to maintain. WHAT I LOVED -The attention to detail was amazing. From laying down protective canvas, to carefully prying out my 50-year old windows without damaging the outdoor brick or indoor drywall. I didn't even need to paint afterwards. -The caulking and insulation job was top notch. Seamless application and done well. Most sealers won't consider that you need to use different caulk thicknesses depending on what part of the window you're sealing. It was obvious that the caulker from WoW used thinner caulk when needed and put wide caulk on when appropriate. Smooth as butter and looks perfect. -Boy did they vacuum. There wasn't a crumb of anything left anywhere when they left. In the end, I feel very confident that if any issues arise, WoW is going to completely take care of it. No dealing with the manufacturer, no second-guessing. This company went out of it's way to make me feel like I was getting white-glove service and I'm repaying the favor with this pretty long review. I hope it helps! I'm so glad I'm done. read more

Bumping this up a star because WoW deserves it. Nearly six months post installation and we couldn't be more pleased with our windows. Exceptional product, exceptional customer service and a fantastic local company. One tip: pay the little bit extra for the foam upgrade-you won't regret it! read more

Very happy with the products and service. We just got two windows, a door and a sliding glass door installed. It took about 5 months for all the pieces to arrive, but I can't fault Windows on Washington for that. Both the salesman and install team were prompt and arrived exactly when they said. We received regular updates from their office regarding the status of our order, without having to prompt or prod them. We even did a change to our order once it was measured and they were very accommodating. The day of the install, their team did their job quickly and did a fantastic job installing everything. The new windows look great and the doors are rock solid. We'll go back to them for all of our future window and door needs, no question. read more

It seems a little redundant to give a 5-star review to a company that already has 147 of them, but strength in numbers, right? Take home message: Simply put, Windows on Washington (WW) is awesome. Do not hesitate to hire them, you're just wasting your own time having a senseless debate. We contacted three window companies for evaluations and estimates. The first place was "meh," at best, with the owner tell me what I wanted instead of listening to what we were saying. You are the expert, I get that. I am the consumer; at least PRETEND like you are considering my needs and concerns into your answers. The second place was WW, and that's where we stopped. Zach, the representative sent to provide the estimate, was super personable, very friendly, and extremely professional. He listened to our thoughts on what we wanted, and gave excellent recommendations. What I really liked about it was that he was not trying to talk us out of anything, but rather provided the pros and cons to each decision. For example, we wanted triple pane glass for various reasons, and he explained how that would be overkill in some instances and not even provide a benefit in others. We were impressed with his knowledge, honesty and customer interaction. He left, and after a fast discussion, my wife and I ran after him and said, "Send a contract. We'll sign it and you're hired." That was May 9. It was smooth sailing after that. An appointment was someone to take exact measurements was scheduled on May 16. I provided a down payment online, and we were told the windows (OKNA Insul-tec 500dx) were ordered but would be delayed (thanks, COVID-19). They arrived in the warehouse on June 24, and installation was scheduled for today, July 9. The install crew was awesome, and I apologize/suck for not recalling their names. They were fantastic and deserve kudos. They arrived around 8:30am, and in just over and hour had the 10 old windows out and the new windows in place. They were gone just before 2pm, with everything complete--cutting and installing outside treatments, caulking, etc. Insane. They cleaned up afterwards and left everything in fantastic shape. Overall, this was just a sensational experience. We expected to pay around $10k for all this, but the final bill was just under $7k. We have excellent windows, with an excellent warranty, and know that everything is backed by outstanding customer service. They were very communicative with inquiries and concerns, which is a big plus with us. I don't expect to need new windows in this house again, but if I do, or if I move into a new house that does need new windows, I will most certainly be making just one call--to Windows on Washington. read more

Detailed review of our experience follows because windows are a big investment! Quick summary at the end if you just want the bottom line. After getting several quotes from the big national window players, we were fed up and feeling hopeless about replacing our windows. Quotes for the job were north of $25,000 for 17 windows (nothing out of the ordinary, no oversized windows, no giant picture windows, no doors) to replace the original wood windows on our 1960s house. That just wasn't going to happen. Finally, off a recommendation on NextDoor, we called Windows on Washington out. Finally, a company that did a sales pitch in a reasonable amount of time. No three hour song and dance (looking at you WINDOW NATION and POWER HOME REMODELING - ugh!). Thanks to Greg for that. He gave us a great product demonstration and helped us pick a middle of the road Okta vinyl window model that would meet our needs. We added triple panes to some south facing windows in areas we have challenges with solar heating during the summer. We also decided to have WoW give us a quote for a 10 foot custom sliding glass door that we wanted to add as part of our kitchen/living area renovation. There was no existing door in this location so this wasn't just swapping doors in and out. The other window companies had given us quotes so high we hadn't even broached this subject with them. Our quote, even including the 10 foot custom glass door was about $24k - $10k of that being for the door (this included demolishing existing exterior brick wall, window and smaller door to create new 10 foot opening, installing new 10 foot LVL header as this was a load bearing exterior wall), $14k for the windows. Working on a budget, we wanted to bring this number down a bit, so we had them take off the demolition and prep of the new 10 foot span, bringing the price down to $19k, and planned to do this job ourselves (do not recommend unless you are a serious DIYer with architectural and engineering knowledge, construction experience plus a whole lot of muscle and tools!) We signed a contract and took advantage of 6 months no interest financing to pay off the windows. WoW sent the crew foreman Young (sorry I don't know for sure the right spelling) for our job out to take formal measurements within a few days. He was the STAR of this entire operation from the moment we met him until completion of install. Thank you Young!!!! Signed contract September. Given 8-10 weeks target for install (have to wait for windows to be made and shipped) - putting us right around Thanksgiving. At about the 10 week mark on November 20 we were notified the materials had arrived in their warehouse and were offered an install date of December 27. Yikes. Not at all what we were told to expect. We pushed back a bit and were given an open "weather day" which they hold open for jobs that can't be completed due to weather - December 11. Install day came and luckily weather was good. Young kept the job moving right along and my husband informed every step of the way as things progressed - especially with the door. We got the thumbs up on our work and the install went smoothly. Young even cut molding for us to trim out the interior side of the new door for when we had new drywall hung. The crew worked speedily and the install was done in one day, everyone cleaned up and the place was spotless afterwards. I have since texted Young a couple questions and he's always responded. Much appreciated Young! The only hiccup was with the door handle on the slider. Apparently the handle style just recently changed and the new style is a HUGE pain to open. If you're a senior or struggle with arthritis I see no way you could operate this door, so take care to double check your handle. The handle unfortunately did not loosen up over time. We contacted WoW and they sent a tech out who swapped our handle for the old traditional sliding door handle. Our tech Bill was great! He let us know that these handles seem to be having issues across the board and also informed that there a variety of handle choices for the door that we should have been presented with when we made our initial selections. We were not told there were any options, unfortunately. SUMMARY All in all, the Okta windows are beautiful, high end looking (if you've seen cheap basic vinyl windows with reduced glass viewing area and junky trim then you know what I mean), fantastic and energy efficient, the trim job on the exterior of our house is wonderful and properly sealed on every single window. The new glass door is spectacular. We appreciated the flexibility of letting us handle demo for the door to save on costs Young was an awesome foreman and a true star employee. Scheduling was a bit tough, but they redeemed themselves by helping us swap out to a better door handle after the job for no cost. Great financing options We have been very happy the last 6 months with our new windows. read more

Customer service and quality are second to none. Took a while to receive but kept us informed throughout. Joon is a master at installation and windows look phenomenal. I would highly recommend. read more

My Previous post was Not Correct. I was referencing the WINDOW WORLD folks out of Chantilly. My short chat with Dave was awesome! I probably should have went with him in the first place. My apologies. I sense that I may have to reach out to them (Hat in Hand) to have them replace a sliding glass door. Again, Dave was very gracious on the phone call when he could have been other than. read more

I have held off on this review hoping the issue with the doors would be resolved and waiting for winter to see if the windows would hold up to the cold. Thankfully the windows seem to be better than those that came with this 1960s build we purchased last year and we do not have an actual draft in the living room. So here is the issue that has me so frustrated, it is our front and side doors. The sales guy (Greg) put so much time into the windows and his presentations, we knew we wanted new windows and we both get that they have been improvements and that we needed new windows. We didn't talk about doors until the after all the window demonstrations were done. I showed Greg pictures of the door models we had liked. He said they could not get us ones with the dental ledge (I learned that term later when trying to get the issue resolved). The doors we showed him were a traditional with a four section half circle window and one with a larger rectangle on the top with six sections and a dental ledge. As I mentioned they apparently did not have the dental ledge option which I begrudgingly accepted, it was late and I was ready to be done with this visit. I did make sure to specifically ask that no peep hole be involved. I was assured this wasn't even something they normally did anymore and we said good. We joked about how it would be ridiculous and where would it go, etc, etc. When it came time for the installation I was shocked to see that the door windows did not have the sectional divides and, wait for it, there were peep holes in both doors. These peep holes are one inch below the window itself so that even if someone did want to use it their head would still show making it completely ridiculous. Add to that the windows are large enough that when either of us stand in front of the door our necks and heads show making you have to wonder what possessed them to add the peep holes (that are not standard) when we specifically made an effort to verify there would not be any such peep holes. When I reached out to Greg after the installation and it was immediately obvious he did not remember the sale and he quickly punted us to a manager, Dave. Fast forward several months later and we still have doors without divides on the windows and with peep holes an inch below the windows. For a while I was told a dental ledge could be placed on both the inside and out to cover the peep hole but even that has trickled out and most recently they want me to pay to replace the doors. I still don't understand why the peep hole cannot be removed and filled and have a dental ledge added on the outside. I have given up on the divides for the door windows and expect I will hire a contractor to try and fix this mess. Since then we have gotten the rest of the windows (we had held on the three bedrooms) replaced by a different vendor leaving me wishing I had connected with the second vendor earlier and wondering if it would have saved us from this door nightmare. If I could give a piece of advice to window/door sales teams it would be if you expect someone to get doors and windows then please, please discuss the doors first as those involve more variables and something your potential customer will see and touch every single day. read more

Our neighbors recommended Windows on Washington (WOW) because they were very pleased with the job the company did for them. We chose WOW as a result, and we couldn't be happier. The windows are beautiful, solid, and well sealed against heat/cold. The crew was meticulous and quickly resolved any minor issues that arose. They were polite, friendly, and professional. Cleanup at the end was amazing. The salesman was also great and stayed in touch throughout. We're very happy with our choice and the end results. We highly recommend WOW. read more

We had Windows on Washington (WoW) install a new sliding glass door and could not be happier with the end result and even the process. Knowing you are likely going to do a lot of research, get multiple cost estimates and then drink heavy amounts of your favorite 'helper' when you finally realize the cost, here is some insight that might make things go more smoothly for you. You may find lower cost estimates; however, you will not find another company that treats your home like it was theirs and have this quality of product to offer. From the initial visit by someone to take measurements, the office staff, and the install team, I quickly knew we had the right company. Everything about this door is exceptional - highly recommend getting the integrated blinds. It does not open as far as my previous (contractor grade) door but that is a very, very small footnote. Joon and his install crew were absolutely amazing in every way; truly courteous and professional in every way. As for COVID-19 concerns, there was a short (couple weeks) delay in getting the door delivered but that was fully expected. The install team wore gloves and masks and also laid a tarp on the floor from the entry into the house to the work location. Overall it took about 3-ish hours to complete everything. It is still too early to tell any difference for warmth or sound but I am sure that will not be an issue. There is no question as to why WoW has such an amazing reputation. Thanks again for helping use to complete this long-awaited upgrade to our home. read more

Windows on Washington - Rain doesn't help but this door is beautiful - Windows Installation Near Me - Sterling, Virginia

I waited a whole year to write this review as I wanted to actually see the workmanship of this company and I am happy to report that there has been no leaks and my condo is cooler and warmer throughout the seasons. They are pricier than other but WOW uses quality windows and you truly get what you pay for. It's worth the price! Joon and his team were great and completed the job in a few hours. Funny thing, I accidentally poked the chalking and was too embarrassed to say anything. One of the workers saw it and fixed it and made fun of me in Spanish which I understood and fessed up to being the fingerer of the chalk. Lol read more
