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

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

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 had just come off a very bad experience with a contractor, and my Windows on Washington experience was an absolute 180. David was a good first point of contact who walked me through my options, was upfront and helpful, and got me the information I needed in a timely manner. Jose and his crew were outstanding on install day. They were quick and professional; my wife commented that besides the new windows there was no evidence anywhere that they had been here. Our order was rather basic but we were treated with respect and professionalism lacking from many companies. I highly recommend them and would use them again in a heartbeat. read more

I highly recommend Windows on Washington for window and door replacement. We had all 10 of the original wood windows and 2 aluminum sliding glass doors in our 1986 townhouse replaced earlier this month, and couldn't be happier. Brandon Shonebarger was a pleasant, straightforward sales representative who patiently answered our many questions during his in-home visit and afterwards. We liked the quality of the Okna windows and doors he recommended, and decided to bet on WoW's reputation for stellar service. Young Kim, the project manager, and his team of installers worked efficiently to complete the job in a day. They were courteous, careful not to damage anything in the house, and cleaned up thoroughly when they were done. Kim is a master craftsman who did a superb job of capping the trim over a half-round window, something that other window replacement contractors told us couldn't be done. WoW's President Eric Novotny even stopped by in the afternoon and helped to install a barrier railing outside a sliding glass door, an "extra" we'd requested. Everyone at WoW went above and beyond, and exceeded my already high expectations. Our house is now warmer, quieter, and looks so much better! read more

I had initially given a very long review on my project with the team. However, i had a remarkable experience that have changed every negative opinion i have about them. So i was called by Windows on Washington to discuss how i can be compensated by moving my projects to 2 weeks earlier. I did and the date was set. When the door arrived and i found out that the colors didn't match my shutters...i was very disappointed but Windows on Washington offered to paint my shutters to match my doors, which was very exceptional. In few minutes, the team arrived my home doing exactly what they promised. I now understand that their greatest goal is customer satisfaction.. I am glad i gave them a second chance. Look forward to the next project with them. read more

We just had WoW replace both sliders (sliding glass doors and screens) in our home, and we couldn't be happier with the finished product. The OKNA Elegante sliders are an amazing upgrade over the original sliders. Not only do they look great, but they slide so easily, and the four point locking system eliminates the need for ugly lock bars. They also have keyed locks, so being able to enter the house via the sliders is a nice bonus. Also gone are those hideous mini-blinds original to the house, as we opted for the internal blinds on the kitchen slider, and hung new curtains on the basement slider. Young, the Project Lead, and his crew did an outstanding job with the installation, and his attention to every detail, no matter how small, is a credit to him and WoW. He even stopped and got out of the truck to pick up a small scrap he saw in our driveway after they had pulled out and about to leave. And this is after he caught a minor issue with a latch on one of the screen doors. He also remembered leading the crew that installed all new windows in our home back in 2013. Another job that they did very well. WoW also installed a new roof at the same time, and no issues with that job either. We are very happy with all of the work that they have done on our house, and recommend them without reservation. A huge thank you to Young and his crew, as well as Brandon, who did the initial consult, and Becky in the office who always kept us informed along the way, and through COVID related material delays. read more

We are extremely happy with our window and door replacement from WoW. For context: We replaced an original drafty wood side door and ~17 drafty wood windows on a 1949 house with lead paint in the windows. We chose a Provia door and we chose Okna 500 windows. We got estimates from three companies -- the big brand one that does the 2 hour demo in your house and uses hard sales tactics (highest quote), Windows on Washington with salesman Jay who was down to earth with us and didn't use tactics (medium quote), and a third smaller vendor who a neighbor used who didn't have the best quality windows but was very nice (lowest quote). In the end, as we read reviews and talked to former Wow customers, we decided on an old 1949 house, we needed quality installers. As there was lead and we have kids, this was also a factor. We also liked what we read about the Okna brand. Our installer was Young Kim and he is exceptional. After we signed our contract, he came and did second measurements, and he was meticulous about measuring our old original side door, which is not a standard size in these 1949 houses. He was responsive through text message with me, which I appreciated. We had to wait about 6 weeks for the window/door order to come in. This is normal, and most vendors told us it takes this long. As we had lead, on installation day we had to leave the house and stayed at a neighbors to be near by. Installation was in May 2019. The team worked very efficiently and got everything done by late afternoon. Young did the trim fitting himself, and we chose a maple color trim to match the mortar on our brick (our salesman Jay had suggested this and it looks fantastic with our brick). The installation was great, and the team cleaned up everything - no trace that they were there. Young stayed later than his team so we could do the final look through, and he then went out and did a final inspection of the outside, going in to our bushes even to pick out some debris he noticed. He is exceptional, as I said. It's mid-summer as I write this. So far I can't tell if the windows are keeping the house cooler or not (just because of the weather changes), but I've noticed the sound is quieter in the house when all the windows are shut and the windows have withstood some heavy rains that have hit our house sideways. (With our old wood windows, rains like that would flood through the storm windows and water would sit in the sill.) I'm looking forward to seeing how the windows perform in winter -- our old windows would have heavy condensation on the inside in winter, and even ice; we had to put up plastic on them. I'll try to post an update on that later. Overall we are very pleased and would work with this company again. If you have an older house and are worried about the trauma of new window and door installation, this is the team to go with. The installation team we worked with was solid. read more

So a little over a week ago we had new windows installed in our home by Windows on Washington. What a fantastic experience! They kept in touch with us every step of the process, we never felt like we had been forgotten. The windows came in sooner they they had quoted, and they worked with our tight schedules to get the install scheduled at a time that worked for us. The day the installers came, they too, kept in touch when they knew they might be later than expected. They finished everything by end of the business day and when they left you could not tell they had been here other than the beautiful new windows!! They cleaned up and left everything neat and tidy. We highly recommend Windows on Washington if this is something you are wanting to do for your home. On a side note, thanks to Zach Wince for all your help and guidance through out the whole process!!! read more

I contacted WOW to replace my windows and can't say enough about their customer service, workmanship, and professionalism. Greg was knowledgeable and easy to work with. Installation and cleanup went smoothly, and the windows look great! This is a top-notch company, from sales, to backend office and production, so kudos to the owner for running a tight ship. I've owned a few homes and contract most of my work out and can honestly say they are by far one of the best companies I've hired to make home improvements. I highly recommend them. Great job! read more

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

Planning replacement windows on a 30 year old house in Long Island, NY. Onljne searches are endless and some very confusing on what product, brand or installation method is best. Came across Eric from Windows on Washington's post and decided to ask some questions. Eric replied almost immediately and had some great info. Wish he did business in my area because he'd be the first I'd call. read more

Windows on Washington is SPECTACULAR. I used them in a townhome in the Fairfax/Annandale area and have been incredibly satisfied with the decision to engage their services. In fact, I really have the feeling that this review is superfluous considering ALL THE OTHER REVIEWS WITH PERFECT, TOP-RATINGS! If the ratings don't inspire you to hire them, then you act to your own detriment(!) Initially, I had planned to buy "the best" windows with famous brands everyone knows. When Greg (the salesperson) visited us, he DEMONSTRATED using SCIENCE how not only were his WINDOWS a superior product at a less-expensive cost, but he supported his assertion that his INSTALLATION CREW was the most experienced in the area. I really shouldn't need to offer a really long review. BEFORE you make any "final" decision to use ANY other Window replacement company, you should schedule a 30-minute consultation with Greg. What possible reason could you have NOT to gain access to the vital, valuable information he can provide?! ANY window replacement/repair is not cheap--but not only are his product the LEAST expensive available, but they're superior in quality compared to ALL other brands INCLUDING the "name brands"--AND HE CAN PROVE IT! I am HIGHLY satisfied with WoW. The installation crew was headed by a REALLY experienced gentleman who obviously CARES (just like Greg) about doing an excellent job, and he supervised his team well. The house was respected, and cleanliness was maintained despite their doing a quality job that was completed pretty quickly in one morning. (WOW even accommodated a close-to-last-minute schedule change.) I believe THIS IS THE ONLY operation in the Northern Virginia area which should be trusted with anything to do with home windows. The combination of professionalism, science-behind-the-product, the high quality of the execution of the Okna window product, and the experience and quality of the installation crew all justified my decision to hire Windows on Washington. Now, I'm merely one of the vast legions of satisfied customers... read more

We just had our four sliding glass doors replaced by Windows on Washington and are very pleased with the results. They provided great customer service and kept us fully informed throughout of the status of our order. The installation itself was very smooth and highly professional -- superb attention to detail by the crew chief. Highly recommend them! read more

This is a company that stand behind their products and installation. We have them installed our windows about 10 years ago. Last week, my wife tilted the window for a cleaning and could not close. She asked me to check without telling me what she has done. Naturally, I tilted the window one more time. Then I heard a cable snapped. After watching youtube video, I realized that both tension cords have snapped. The window was inoperable and we can't tilt it anymore. I gave them a call and they setup appointment immediately. A window tech came and fixed it in less than half hour. We have been very happy with the windows and this last experience made it even better. We'll definitely call them if we ever need windows replacement again. Thanks WoW !! read more

Once our new windows arrived, their installation team did a wonderful job installing them, along with our new doors! Their pricing beat the competition's and the service level was excellent! We definitely will use them again for our next window project!! Definite 5-Star! read more

Windows on Washington - Windows on Washington front door - Windows Installation Near Me - Sterling, Virginia

Top notch company, great home solutions, and white glove service at a great price. We ordered a complete front door replacement system which included a number of pieces of glass sidelites and transoms. The door order, delivery, and installation was completely seamless. Their staff and installers are very professional, courteous, and sensitive to our needs and requirements. They are completely trustworthy and a company we'll work with again on other house projects. Thankyou Windows on Washington! read more

These guys were awesome. I really appreciate the professionalism and they were not pushy! Which was awesome! The prices were much better than other offers and the quality was great. They wrapped the frame which most places don't offer with installation. read more

Windows on Washington - Windows Installation Near Me - Sterling, Virginia

From the initial consultation (via Zoom for safety), all the way to installation, WoW staff were prompt, knowledgeable, and professional. Our new windows are great quality and we know they'll increase the value of our home. No hidden costs or confusing promotions, just a solid company doing solid work. Highly recommend. read more

Read all the other reviews, and you will understand. 5 stars, go with WoW! They make sure everything is perfect and won't stop until you are 100% satisfied read more

I've had these windows for about a year now. I wanted to give them a full winter cycle before writing at a review. WOW was the third window company that gave me a consultation and it turns out that third time's a charm. The first company tried to give me a hard sell with over three hours of talking. He was a nice guy, but about 2 hours in, I realized I had a soothsayer on my hands. I spent so much quality time with the guy that I felt guilty not buying windows. I ended up giving him a Spiderman 3 DVD for wasting his time (no lie). The second company had quality windows, but they were just way too expensive. In comes Windows on Washington to save the day! Greg came in for a consultation and we instantly hit it off. We actually ended up hearing each other's life stories (no lie). The process wasn't exceptionally long and he was able to answer all my questions. From one Greg to another, I really enjoyed his professionalism and helpfulness. The windows from WOW are great quality at a great value. They give you two models to choose from. I got the less advanced model, and so far, so good. The windows are great on energy and easy to open and close with the fixtures. Before these windows, my bedroom would be so cold in the winter. It felt like I was practically sleeping outside some nights. Now, my room keeps a good temperature. The installation process was smooth. We had one little hiccup where they wrote down the wrong measurement and had to come back and do it a few weeks later, but everything else went smoothly. I recommend this company. From my understanding, they are a family business that feeds off of word-of-mouth. They have my stamp of approval. read more

BLUF: I worked in the high-end window and door world for 4 years and have to say that this company is FANTASTIC. We will use nobody else for window or door needs moving forward. We live in North Old Town Alexandria and needed to replace the original exterior basement door that was a custom size in a cramped space with a frame that was incorrectly built into the brickwork by the original builder. Most companies we contacted looked at the small door size and location of the install and said some version of "sorry, no way this is doable." Some said it was because they couldn't do a door in that size and others because they couldn't handle the complicated install. The only company other than Windows on Washington that did say they could do it quoted us over $7,000. We were starting to think this wasn't going to be feasible when Jay came to our house to do a free site survey and provide a quote. Where most salespeople are in a rush and always looking to up-sell or push you for things you don't need, Jay was the opposite. First and foremost, the man knows his doors and windows. I never mention my background in the industry because I like to see if the people I'm talking to know what they are doing, and simply put Jay is an expert. He knows the products, the area, the regs, and the intricacies of installation like the back of his hand. At no point was he pushy; on the contrary, he walked us through every option there was, including DIY options. He explained that this had to be a custom project, but that wouldn't be an issue and showed us the PROVIA options that would work. Most importantly, the quote was very reasonable and less than half of what we had been quoted by the other company! Once we decided to move forward with Windows on Washington, which was a no-brainer at that point, the company was great about communicating with us about next steps. They worked around our hectic schedule to have an install team come out to do a full survey and get another set of measurements to ensure the door being ordered would be exactly what we needed. They also took the time to see how our drainage system worked, as our drainage pipe is right next to where the door was being installed. Then COVID-19 happened. The company stayed in touch with us noting the door had arrived, but not rushing us at all. They said we could hold it with them as long as we wanted until we were comfortable doing the installation. They also explained the various mitigation measures they put in place to keep everyone safe (masks, gloves, taping off the work area, etc.) We decided to set the date 6 weeks out and on the day of the job Joon showed up with his team ready to get to work. First, they taped off the work area as promised and did an amazing job double wrapping our washer and dryer, which are right next to the install site. Joon then walked me through exactly what he was going to do, which I really appreciated. I was worried the install would take a long time or be crazy loud (we have young kids) and boy was I wrong. Joon is clearly a master at his craft because three hours after arriving, the job was done. When Joon was showing us the finished product, he looked down noticing a smudge of brick dust on a base board, apologized and immediately took care of it. The attention to detail was extraordinary and something rarely seen with other people we've had work on our home. I can't recommend the company, Jay, or Joon highly enough. read more

My second project with WoW. Window replacement this time; 5 windows in the middle of winter. Smooth, professional results. The installation team and the sales/operations teams all function as a well-oiled machine. High-quality OKNA windows are draft-free and look terrific! Call them for an estimate, you'll be glad you did! read more

The team at Windows On Washington is Fantastic. They were professional, very courteous, and experts in their trade. The installers were efficient did an excellent job. The Office Staff was easy to deal with and responsive. read more

Very highly recommend. The whole process was great and we felt very comfortable throughout. The sales pitch was not pushy at all and everything was clearly explained. Installation was great. The team showed up on time. Everyone wore masks and shoe covers. They worked quickly- did 10 windows in a townhouse in about 5 hours. Everything was kept clean the whole time, scrap was removed periodically. The team lead took time out to answer questions we had and clarify parts of installation if we had questions. At the end the lead took us to each window to make sure we were happy with installation, insulation, finishing, and clean up. I can't recommend them enough. The windows have made a massive difference already. Very happy with Windows on Washington. read more

My new deck door was installed and I absolutely love it. I hesitated to go with the company at first because there were more affordable options other places. But I am SO glad I did this. My door is perfect. There is no noise from the outside, and no cold gets in, even when standing right next to the door. It is worth every penny. The installation folks were awesome too. I don't think I've ever experienced such professional service in my 30-plus years of home ownership. read more

They just installed my windows and 2 sliding glass doors. The crew are perfectionist. They made sure it was done right. I love my windows. They cleaned up afterwards like they never were here. I cannot say enough good things about this company. Interviewed several companies and so happy to have gone with them. Jay was our sales person and he went beyond selling and worked with our HOA fir approval. I highly recommend this company they give lifetime guarantee. read more

We had a great experience with Windows on Washington! We purchased a sliding door for our kitchen and an exterior door for our garage and both are excellent quality. Joon did a truly fantastic job installing both and would highly recommend this company to anyone looking looking for sliding doors or exterior doors. And customer service is fantastic. We had a small issue with the screen and they took care of it right away. Very happy customer! read more

Windows on Washington - OKNA sliding patio door. Excellent quality! - Windows Installation Near Me - Sterling, Virginia

Very happy with my windows and the service provided. We had 8 non-standard windows and 3 sliding glass doors replaced, so it was a big and pricey job. We had several quotes and WoW was very competitive in their pricing. We really appreciated that the sales rep who came for our initial estimate wasn't doing a hard sell, but instead gave us a very thorough and informative description of the window options, benefits, etc. We learned more from this person than any of the other companies that gave us quotes, and never felt pressured to make a decision. After deciding to work with WoW, they were easy to communicate with and kept us updated through the whole process. On instillation day they took great care with ensuring everything was done correctly and cleaning up after, then walking us through each window to ensure that we checked each one out. The workmanship was fantastic, and 3 months later and we couldn't be more pleased with our new windows. We would absolutely do business with WoW again (next project - gutters!) and recommend them to anyone. read more

We finally replaced our original windows (1967!) and are extremely happy with our choice of Windows on Washington. Everything about the processes was fantastic, from the information/bid gathering to the planning to installment to the product. Initial consultation: We had several other bids from other companies with extremely pushy salespeople ("sign tonight or your "deal" will fall through!!", even though the "deal" was approaching twice our other bids). Brandon from Windows on Washington was knowledgeable, professional, not pushy and he gave us a straight forward, no-nonsense bid. The contrast was dramatic. Planning: WoW was extremely professional, and focused on our interests. When we changed our minds about the color of the outside flashing at the very last minute (3 days before the installment!), even though they had confirmed our initial choice twice the month before, they didn't bat an eye at the change. The color we wanted was not in stock, and they offered either to postpone our installment and get the color of our choice or to use another very closely matched color they had in stock. We chose the nearly identical color they had in stock, and I was impressed with how positive and accommodating to our desires they were. Installment: The installment team, let by Joon, was outstandingly meticulous. The work was clean and efficient, I note that *every* single time they entered the house, they took their shoes off. We replaced all the windows on a large town house (29 windows!) and they were done in a day and half, leaving the house spotless when they were done. They even removed and reinstalled the safety bars on the 7 downstairs windows (which I note that some of the other companies refused to do, saying we had to find our own outside contractor.) Joon is a true professional who clearly takes pride in high quality work. Product: The Okna windows WoW uses are great. Some other companies will try and disparage vinyl windows, but these are high quality, great looking windows. Simply put, it was one of the best contracting / house project experiences we've had. read more

Honest and knowledgeable company. An unfortunate situation worked in my favor when I contacted another company that told me I needed a window replacement, they were unresponsive when I was trying to book the replacement appointment with them so i contacted windows on Washington. I'm so glad I did! The person who came by the look at the window informed me that I did not need a new window, just some new parts that are covered under warranty. He took a picture of the serial number for me and gave me instructions on what to say when I contacted the warranty department. He didn't even charge me for his time to come out and take a look. Saved me thousands of dollars. Very honest, knowledgeable and helpful people. Thank you so very much! Will reach out again the next time I'm in need of new windows and will recommend to all my friends and colleagues. read more

Start to finish, terrific experience. We have used other window companies with connections I have in real estate, but they did not compare. WoW provided clear communication, the items ordered were exactly what we wanted, and installation happened on time. Absolutely no complaints, we are very happy with the results and will be returning customers. I also am very confident in referring this company out to my clients as well. I'd add a big thank you to Brandon in sales and Julia and staff in the office. Crew that came for installation was exactly how we like to see it, they were super neat and easy to work with. read more

We were looking to replace all of the windows and doors in our house (over 35 years old) and looked at a number of contractors. We are so happy that we chose Windows On Washington. The initial sales pitch was not pushy at all and he gladly answered all of our questions and was really informative. The management and communication of timelines on progress and the installation date was spot on. Finally, the installation could not have gone more smoother. They replaced all the windows in 2 days, were efficient, courteous and cleaned up the house as if it was their own. The quality of installation and the windows\doors are simply excellent. read more

Laurie Grant, Central Reston I used Windows on Washington for some work on my mother's home in Ashburn because we needed to sell it. Eric and Sean are both amazing! Very prompt, very knowledgeable and very honest! I never felt like they were trying to "sell" me in any way. I trusted their professional advice and the outcome was better than expected. I will definitely use them on my own residence if I ever need to. read more

WOW helped us replace one sliding glass door, two windows, and building a basement egress. It was a two-day project due to the concrete cutting that was needed. WOW was the only windows company that could provide both window and egress services. The price was fair given the size of the work. Jim and Zach were particularly helpful in taking care of us, being responsive, and handling some unexpected things that came up without extra cost. We truly appreciated their work! read more

Professional and detail-oriented. Zach Wince, who worked with our family on several projects, is honest, down-to-earth, and very accommodating; he took his time in creating different quotes, helping us decide the best financial course for our repairs. Our duplex had metal-frame windows that were beginning to leak, on top of a layer of lead paint to contend with. But we are happily enjoying our new windows and can now watch the rain fall in peace instead of having to grab glasses and mugs to catch leaking water. I'm not kidding lol Really happy with this service. read more

Every step of the process was exceptionally professional. The end result was a level of polish and quality that I didn't anticipate. I'm thrilled with how it all went. (Note: there's a cheaper company out there, but I chose WoW because I wanted great insulation instead of cheap windows that are going to leak. I'm very happy I made that decision!) read more

These guys did a wonderful job installing windows in our sunroom. They were professional, cleaned up after themselves, and the windows are amazing. It did take about 8 weeks to get our windows made but this was due to the pandemic. I think the lead installer was John (?). He and the crew were excellent. Will definitely work with them in the future. read more
