Sliding barn doors are great for giving my home a modern look while saving interior space. I needed installation of 2 sliding barn doors in a part of my home where was little space to install them. 3 installers from different companies came to my home and all believed it was not possible to install such doors in this small space. But, when I asked Best Window Work's owner (Ken) for the possibility or impossibility of installing the doors, he confidently said his company was able to do in the best way. The workmen were very knowledgeable and tried very hard to complete the job. After 2 days hard working the project was completed in a completely satisfactory manner. I am very happy with my new Sliding barn doors. A wonderful addition to my home. And the last sentence! If you want to make the impossible, possible, be sure to ask from Best Window Work! read more

Ken was very communicative as we were dealing with a new property manager, a sale of a unit and going between a seller and new buyer to get a window ordered and installed. Lots of moving parts, but he knew how to get the job done quick and easy with all the different people involved. Thank you Ken. read more

Excellent attention to detail. The team works efficiently and communicates well: answers phone calls, text messages, and emails quickly. Highly recommended. read more

Based on my next neighbor's recommendation I contacted this company to replace all my old upstairs windows with more energy efficient ones. The fact that my neighbor's windows are almost 10 years old and trouble free persuaded me to use this company over others. Ken, the owner, was wonderful to work with - knowledgeable, trustworthy and has great communication/follow through. My original windows were a bit more complicated as the previous home owner did some non-standard installations which required more effort but the experienced team did an excellent job and in a timely manner. The owner then did a final inspection which I very much appreciated. Very pleased with my new windows! read more

Best window work recently replaced all of our windows. We had previously used this company to replace our sliding doors and were very happy with that experience. So, we decided to use them again for our new windows. Through the process, Ken was professional, friendly, and responsive. He provided us with various window options. Pricing was competitive, transparent, and reasonable. Ken and his team arrived on time and efficiently installed the windows. By the end of the day, we had new windows which were beautiful. Highly recommend! read more

Ken and his team did a total of 23 windows and 3 sliders, all turned out very nice, great quality for a reasonable price. The best part is during a recent storm one of the stationary windows was leaking, these guys came out on a Saturday and assessed it was not the window but coming from a roof deck above. They re-sealed areas of the window to give it a chance against the water that was coming from above, just in time for another big storm. Ended up being a stucco leak from above. I recently had them replace a front door on a studio apartment. The price was good, their work is excellent and because he had a cancellation I was able to get all purchased and completed within 3 days! The door is beautiful and the installation was tricky because of the old construction of the existing door. Ken and his team can figure out any odd issue that might occur, had some similar issues on the windows and all turned out perfect. These guys know what they are doing and are very fairly priced. I highly recommend this company. read more

Ken was referred through our contractor, and I am so glad he was! Excellent job replacing 3 windows and a patio slider, in addition to installing 3 windows that did not before exist.

The windows he sells are of high quality at a reasonable price. His window installers were very nice, efficient and kept the working areas very clean. I highly recommend this company. read more

Ken was referred to us by family friends who used him and spoke very highly of him and his installers. We gave him a call and met with him, right away we could tell he was the right fit for us, he answered all of our questions, explained the job in detail, so we hired him. Ken and his 2 wonderful installers Paul and Saul showed up on time, let us know what the plan was for the day, put down drop clothes, vacuum and cleaned as they went. They all are very professional and respectful of your home and belongings. They are very easy to do business with. They are honest, fair, listen to your concerns and try their best to make sure things go smoothly. We are very happy with the whole process of installing our windows and the finish job looks amazing. Highly recommend Ken and his wonderful installers. Thank you guys! read more

Ken and his crew installed all new windows in our master bedroom bathroom. Ken's team were efficient, on time, and skilled at what they do; made the process seamless and everything looks great as always. Ken will be our guy for future windows. I highly recommend him and his team very professional workers. read more

I've been delaying the installation of my windows for a few years and now that I finally decided to do it... I thought, what was I waiting for? The installation took one day for all 9 windows and a sliding door and then 1 day for the french door. So beautiful and makes a difference in the temperature inside. I don't feel cold at night. Tge workers were quick and efficient. Thank you. Ken... was available whenever any questions were needing answers. Thank you again. Love the new look of my home! read more

Ken helped me to replace two windows. He is fair person and knows what he does. He is on time and when promises schedules, you can count on them. In addition, his team is professional and works clean and well. I was satisfied with the work and highly rewcommned him! read more

Ken was fantastic, knowledgeable and very patient when it came to our many questions about the install/window type/recommendations etc. His crew (who he has had for years) was extremely competent and did not "rush" the install...they took the right amount of time and the windows look great as a result. I would highly recommend Ken and Best Window Work for any window centric job as they exceeded my expectations in every way. Thanks-David W read more

We've hired Ken twice, and he's been outstanding both times. We first hired Ken to replace half the windows on our house with energy efficient ones. He took our window measurements carefully, making sure that each window was square and that the new windows would fit. He kept in touch with the distributor so that he knew when our windows would arrive. When they did, his crew was on-site the next day. He told us to expect two days of work. Instead they finished in one. When a couple pieces of vinyl trim came loose a few weeks later, he promptly sent one of his crew to reattach them. We were very happy with Ken, so when we decided to replace the rest of our windows and our patio door, we knew we wanted to work with him again. Just like before, he took careful measurements, and he coordinated with the distributor so that his crew could start work soon after the windows arrived. He had also seen that the patio door we wanted might not fit our existing sill, so he came prepared to replace the sill if necessary. This was a more difficult job because these windows were larger and some were on the second floor. Ken's crew still managed to finish most of the job in one day. The most difficult part was a window with a half-round at the top. The window opening was slightly out of round, so the manufacturer's trim didn't quite fit. Ken found us a company that made custom trim, and he came back to install it for free. Ken is a professional. He was always on-time and in touch. He provided written estimates both times, and he told us honestly that one of our windows didn't need replacing (it had been replaced during a recent kitchen remodel). It was a pleasure working with him. read more

If you are looking to have windows and doors installed, look no further and just use these guys. Ken and his crew are reliable (they actually show up when they say!), friendly, clean, and just overall awesome and easy to work with. I felt like the pricing was fair, and the quality of the work was excellent. We are loving our 3 new large windows and front door. Highly recommend this company for your window and door work. read more

I am a property manager and a home owner and we have had Best Window Works install windows on our rentals and for me personally. Ken and his installers were by far the best I have worked with; on time, professional but friendly and by far offered the best price. Because I am a property manager, I did my research and they were hundreds of dollars below the average price of the big window companies; however their work was as good or even better. I am definitely keeping them on my vendor list and already I have another job for them. Thank you Ken for your professional attitude and great work. read more

Ken and his assistant were absolutely wonderful to work with! We are enjoying our new garden window. We will definitely call the in the future for other window needs. read more

Excellent all around from A to Z. Ken along with Paul and Saul (hope i spelled the names correctly) were very professional and did a great all day job. Most importantly the windows look 10 times better and hopefully the energy savings begin immediately for the long run investment. read more

Ken and his team did a great job of installing new windows in our condo. His communication was top notch. Every detail of the time line was shared with us. The windows were installed on time. The crew was polite, dependable and did an excellent clean up job. I would definitely recommend Best Window Work for any future windows installation. read more

Ken Farzin and the crew did an amazing job on my new windows this week! Prompt, meticulous, windows work great and look beautiful and reasonably priced too!! read more

Ken and Saul were great! They installed the sliding glass door and screen for us. Not only did they have the best prices after calling around, they were great with communication. They communicated from the beginning of the job to letting us know when it was completed. They answered any questions we had. By the way the sliding glass door looked awesome! I would give Ken and his crew more stars if I could. Thank you for everything! We will be calling you again soon for the other windows. It was great dealing with Best Window Work! All the Best, Jason & Luciana read more

Best Window Work was recommended to us by our neighbor and you know what they say??... The best advertisement is 'word of mouth'. Ken came out to give an estimate and I got a lot more than that. The first 1/2 hour was spent educating me on the quality of his product, which is made in the U.S.A. My wife and I have noticed a big difference in how cool our house is since these new windows have been installed. We had all of our windows replaced at a very reasonable and fair price. The installers were polite, on time and left our house very clean. Did I mention that we LOVE OUR NEW WINDOWS?! I would HIGHLY recommend this company to anyone in need of new windows. Dave :) read more

We had (9) retrofit windows & (2) retrofit sliders installed at our condo in Scripps Ranch. We interviewed about 5 installers. Ken answered all our questions and understood all aspects of installing the windows and doors. He was by far the most knowledgeable & friendliest installer that we interviewed. He brought up items to insure a proper install that the other contractors never mentioned. I was more interested in getting the job done right & hassle free than price. His pricing was very good and the the crew were true craftsmen that did an excellent job on installation day. Ken was there off & on during both days of the install to make sure it was a quality job and it passed my personal "Tom Code". During the install Ken took care of any small items we brought up on the spot and made sure we were 100% satisfied. Ken and his crew are total experts and I highly recommend them for your windows & doors installs. read more

Wow, what a value. The guy who came out to measure was a very chill, and down-to-earth guy. These guys were the 3rd quote I've received, and they had the best price. It's not a name-brand window, because they build and install their own windows. I've had all the windows replaced at my small condo, and the difference in sound dampening was immediate. One of my beds is close to the window, and it'd be rather cold at night; despite that window being closed. After the new installation, the temperature is remarkably normalized throughout the day. That bed room is no longer cold; and I don't wake up in the middle of the night due to the temperature. These windows are most likely the same windows as the Alside Exaliber (A decent, budget window.. not the best, but good enough for San Diego weather :P ). They look very attractive from inside and out. Lifetime warranty with labor is a nice thing to keep my mind at ease. The installation was quick, and the installers cleaned up everything after the install. They were two really cool dudes, but were very professional during the installation. I know I've seen some bad reviews of window world, but those were from other cities. These guys in SD know what they're doing and selling. I completely recommend them. read more

Just like most people should, I shopped around and got quotes from about 4-5 different companies. Ken was the last one I contacted and I must say, I definitely saved the best for last! Ken was super friendly, explained everything very well and to my satisfaction, demonstrated the windows to me effectively, and to top it all off, he had the best pricing out of everyone! So Ken was the face of the company, now you have to worry about how the team is going to perform on game day. They came out, did all the prep work and got all of the windows and an amazing high quality looking sliding door installed all within one day. There were about 6 windows all together + add in the sliding door. His staff was very respectful, worked hard, and most importantly, got the job done right. Other neighbors I've talked to paid almost twice as much and the job doesn't look as good as ours. If you have window needs, you've found the right people. I highly recommend Ken and his team! The windows are a good product, me and my wife felt weird the first couple of days, b/c we could no longer hear all the commotion outside and it was now so quiet in our room. They also regulate the temperature a lot better than the older windows we had. On a hot day, we could barely stand to stay upstairs, now there is a very significant difference in temp. If your shopping for window work, you better get the best. Call these guys to your house and make sure you get a good quote before committing to anyone else! Best wishes to all! Niko read more

Ken replaced all the windows for my apartment building in San Diego. I'm typically reluctant to write reviews for a company because the selfish side of me wants them to never grow so big that they don't have time for me the next time I need them. However, I was so satisfied with not only the quality of work from Ken, but also my overall customer experience, I felt I owed him a yelp review. The new windows have made a drastic improvement to my building's curb appeal. Keep up the good work Ken. Just please make sure to make time for me when I need you for our next project. read more

Best Window Work is just that - the BEST windows work!!! My wife and I were very cautious because of all the contractor horror stories out there. We decided to interview 5 companies and a friend told me about Ken and his company. He was no nonsense and did not stay at my house 1.5-2.5 hours. He gave us some great ideas for our 15 window and over-sized slider. WOW!!! the work was completed in 2 days with a crew that had their eyes on details and did everything Ken had promised. We could not be happier with the entire experience. AND, btw - we were quoted a fantastic price. We now have a huge upgrade to the look of our house and more importantly the sound of the nearby freeway has vanished. We are very thankful to have found Ken and his company Best Window Work. Thank you Ken!!! read more

Ken explained everything regarding choices we had. A couple of communication issues, since they provided quotes with many neighbors and sometimes called them for delivery issues. Aside from that, I LOVE my windows and they fit perfectly. The guys who installed them finished in one day. All respectful and wore masks. I would recommend them and use them again. read more

Ken made getting our new windows such an easy process. He is professional, responds to emails and phone calls quickly, and got the job done within our desired time frame and at a great price. Thank you Ken, I am recommending you and Best Window Work to everyone I know that is thinking about getting new windows. read more

I was overall very satisfied with the quality of Windows and workmanship. The price was lower than some other companies but most important customer service. They showed up on time and as promised. Installers were very friendly. Ken went out of his way to make sure all parts are delivered and made any correction as needed. He really has a I do care attitude. Thank you Ken. read more

Ken was amazing to deal with and we couldn't be happier with our new windows and the whole process! We received 4 different quotes and I really appreciated that on my very first call to Ken he confirmed a time to come out right away to view the property, asked me what I was looking for, described my options, laid out the timeline and helped ensure that I had everything I needed to make this a smooth process. When he came out he walked me through everything and got a quote over to me faster than any other company that came out. Just in dealing with Ken I knew I wanted to go with Best Window Work and he made it so easy for me to decide when his quote came in the best! We just had our windows installed by Ken's amazing team and Sam did an amazing job. Our windows are perfect! Sam took his time, laid down stuff to make sure our house stayed clean and he arrived on time and cleaned everything up at the end of the day. I don't think I've ever worked with a contractor that laid out a timeline and actually stuck to it but Best Window Work was spot on! They did everything on the day they said they would and finished on time. The windows look great and work great too! All our neighbors have come by to comment how great it looks. Thank you so much Ken and Sam - we couldn't be happier! read more

Window World San Diego is a great window company to consider if you're looking for window replacement. We got three bids and they came in with the lowest price. I also researched them on JD Powers and they were rated the #2 in overall service. We highly recommend them if you are looking for a great value! read more

We love our new windows! The installation of our new windows was more challenging than most. We have vinyl siding on our home and it made the installation much harder for the crew. They did an outstanding job, if I could I would give them 10 stars. From the time we were given the estimate until the installers arrived, we were told they would do their best to not damage the vinyl. They said this was going to be challenging for them. We felt their prices were very good and everyone from the company was so nice and friendly. We recommend WW to anyone considering window replacement, they are the BEST! read more

Just had a window replaced with a sliding glass door and it looks beautiful. Ken is very professional , arrives on time, keeps you up to date on your project and follows up after installation. My project was small but he had no objections to doing the work at a very reasonable price. Ken's crew arrived on time and did the work expertly. I would recommend this company for any window work. Diann read more

When we moved into our house, it had only half of the windows upgraded. We really liked the upgraded ones and could feel the difference. After a couple of years we decided to upgrade the other half. Ken (who installed the first half for the original owners) was very nice and offered the best quote among the window installers that we had screened. The work was done quickly and cleanly. Also, one of the older panels (installed 3 years ago) had developed some stains. Ken had arranged for the manufacturer to replace the panel under warranty, and when the manufacturer balked at paying for the labor (because we are not the original owners), Ken's assistant replaced the panel for free. read more

Ken did a great job! We are very very happy with our windows and highly recommend Best Window Work!

Ken and his install team did a great job installing all new windows and doors at my home. Ken was with me every step of the way; from measuring, ordering the windows and being at my home to oversee installation The install crew where considerate and finished in a timely manner. read more

Ken of Best Window Work was very friendly, knowledgable and not pushy at all when he came out to give me a bid on 3 windows and a sliding glass door. His workers were also very competent and friendly. The price was great. The reason for 4 out of 5 stars was they didn't clean the windows when they were finished. However, that being said, I am having him do another bid for me and he said that he would compensate me for my trouble in his next bid. All in all, very satisfied by this company. read more
