We have 4 windows which need to be replaced. I called Abstract Windows and Dimitar came over, and gave me an offer. We decided to do the window with Abstract. It turned out that they did really nice job. First, we particularly like his team arrived on time and finished the job in high quality. Secondly, when they found the window in living room has a minor problem (The window is in locked position, but the handle bar did not show it is locked). Even though it is a manufacture issue, Dimitar arranged his technician came over and fixed the problem. The installation of new windows are done in high quality. We appreciate the great job by Abstract Window's crew. read more

Don't spend any more time looking for a window installer/supplier. Dimitar and his team did a fantastic job replacing 25 single pane windows and doors in my 1930s home in Oakland with beautiful double pane windows. They were professional, worked efficiently, kept my home clean, and kept their word on every detail. They were competitive in cost and I am thrilled with the final result. I can't recommend these guys enough! read more

Dimitar and his crew were AMAZING!! We had a tricky install and they did a creative and meticulous job. We own a 100 year old Spanish bungalow with two very large picture windows in the front. No one makes the same arched shape anymore so Dimitar came up with a very creative solution to preserve the old, beautiful moldings and fill in the gaps seamlessly. I highly recommend them!! read more

So we had a quote for the quite line windows install. Not only did they come out a give us a quote but then came back 10 months later when we were ready. They scheduled the install after the windows came in and completed it in half the time. My new favorite window company! read more

Know in advance I'm anal & picky about detail to quality work! Just had DIMITAR and his assistant for years Jorge do a install of Milgard Tuscany Windows on my SF Sunset home. Design they suggested was sleek & modern. Comes with lifetime manufacturer warranty. The real plus is their quality of work on the install & clean up afterwards. They perfected the double seal on both sides of the window, they foam spray to fill in the empty space between window and newly installed trims. Installed the protective flashing film around entire window. They pay attention to the aesthetic look of the trim. Seamless to the eye the way the trim blends in with the window. High quality caulking material from CRL. Just quality all around and cleaned up as is they never came. read more

I had a wonderful experience. Ordered 12 new windows and 2 sliding glass doors. This team of professionals were wonderful, courteous wore PPE and completed 95% of the work all in one day. I was so worried that dry rot might have been present and what that could lead to. Dimitar and his team identified and corrected all my issues with minimal down time. Jorge came back the next morning just to double seal and complete the stucco work - I am over the top happy with the whole experience. I should add that I did my 2nd level windows two years ago and had the same 5-Star treatment!! Thanks to the whole crew!!! read more

I have had problems off and on with leaking windows and I needed some expert advice. I really appreciated how Dimitar quizzed me on the problem over the phone. He seemed to want to get to the root of the problem. Once he had a good idea of the issue, he set the appointment. (Most other companies I contacted just wanted to send a salesperson...they did not try to diagnose the issue first). Dimitar came to my house right on time. He looked at the windows and told me how to fix the problem myself, and it was an easy solution. I'm hoping it will work, but it's worth a try because Dimitar didn't want me to needlessly and expensively replace my windows. If it doesn't fix the problem, I'll definitely call Abstract back. It was really nice to have someone come out, tell me the solution to my problem, and not charge me anything. Thanks for the help! read more

Dimitar and his team are always such a pleasure to work with. They're prompt, clean, respectful and have a good humor about them when they're at work. We had the crew punch out 2 new windows and a patio door plus remodel the rest of the windows in the house, and we couldn't be happier. Their attention to detail is superb and they're able to proactively identify flaws and fix them which in all honesty, I would have never even noticed! I look forward to working with this crew again on our next remodel! read more

Dimitar is very experienced and responsive. I contacted him about the leak in one of the windows and he picked up the phone immediately every time. He also is very professional and helpful. Instead of pushing me to replace the window, he offered to come to my house to look at the windows. He also offered me alternative option. I eventually took the alternative option he recommended based on the calculated risk that I am taking. He immediately sent his workers over the next day. They recaulked the inside and outside of the window and got the job done within an hour. Dimitar also helped me to take out the window screen so I could take them to the screen shop for replacement. When I mentioned I have difficulty transporting the screens, he offered to help and pick up the screens and put them back in the windows for me. Dimitar by far is the most responsive and pleasant person to deal with. I would not hesitate to recommend him to anyone who needs help with window replacement. read more

Thorough, fairly priced, patient and professional. After the excruciatingly painful process of collecting overpriced quotes from various window replacement outfits in the Bay Area, we were thankful to find Dimitar and his crew who we hired through Lowes, to replace every window in our South SF home. Dimitar was extremely patient with explaining the process and even stayed late the day installation took place to make sure we were 100% satisfied with the job. When it comes to hiring in the Bay Area, the high level of demand means you are sometimes forced to settle with less than the best to get a project done. With Dimitar and the team at Abstract windows, you can be 100% confident you are getting the best there is to offer. read more

I am a designer and I have worked with many contractors at work. This company is my favorite window install company because the crew is professional, fast, and their price is competitive. They installed six windows for my house one year ago. Three of the six are at large size of 110" x 48" on the second floors. They installed scaffolds. All installation jobs were done in a day and their stucco team come back for the patching. Later we had a crack on the wall. I called the owner Dimiter. He responded promptly and came to my place on the second day and we found out it is not caused by the windows. And he filled a small crack between the window and the trim. Overall, they are professional and provide good customer service after the job done. I have recommended the company to many friends and clients. read more

Thanks so much Dimitar for helping my family and replacing a part on a window. I really appreciated your help as did they !

Very knowledgeable and great at problem solving unforeseen site conditions which may arise. They replaced all of my windows and doors for my home. Reasonable pricing and reliable. read more

I had an appointment for an estimate to install new windows/doors based on the positive reviews. Dimitar did not show up. I waited 30 min past our appointment time and still no show. I called and left a voicemail and texted him. A few days later, still did not receive a call/text from this business. What a joke! read more

After some major remodeling work, I found out that the new windows and sliding doors that were installed were leaking! I had many problems with the contractor, so I didn't want to use him again. Instead, I called Abstract Windows on recommendation by my handyman. I had them replace the windows and doors that were leaking, as well as three other windows in the house. I'm very grateful for the work they did. I'm not very experienced with contractors/construction, but I can say after dealing with the bad contractor I had, it was like light from heaven working with Dmitar, as well as his partner also named Dmitar, and his crew. Dmitar is an excellent communicator which often will avoid problems down the road. I found Dmitar's work ethic to be impeccable. Their attention to even the smallest details reflects a commitment to pride of work, which is rare nowadays. The new windows and doors were installed flawlessly and the work areas were clean and free of debris. (Dmitar #2 even refused to put some minor trash in my garbage can which I offered him to do, instead insisting on taking it with him!) Regarding pricing, I didn't shop around that much, but I believe Dmitar offers a fair price and a fair profit for himself. In return, he doesn't nickle and dime and he will come back for any follow up work to make sure everything is perfect. I will gladly call Dmitar anytime I have any window needs. I really liked working with both Dmitars and I trust them both. read more

Great companies fix their mistakes, and that's exactly what Dimitar has done. After my original review, he personally inspected our project and had the crew return to re-do the stucco. And I'm pleased to say that it looks FANTASTIC! All companies make mistakes, but it's how a company deals with problems that tells the complete story. Dimitar obviously cares about doing quality work - and making sure his customers are happy. We will hire Abstract again, for sure. read more

Dimitar and his Abstract Windows crew did a great job replacing all of the original windows (23) and the front and back doors in our 1929 home in Oakland in April 2020. The job took only one day and the results are spectacular. Dimitar shepherded the project from start to finish: measuring and tabulating windows needed, then double checking before ordering, personally supervising the eight-man crew on installation day, and then walking me through the completed job to be sure that I got all my questions answered and was satisfied with the work. Every thing went off without a hitch --- I highly recommend Abstract Windows! read more

Dimitri and his team did a fantastic job professionally installing a 16 ft wide sliding patio door, in half a day. He got a crew of 5-6 people, himself included, and worked diligently to get the job done with perfection. Cleaned up the job site well too. He accommodated by scheduling needs too. He was subcontracted by Home Depot, who I had placed the order with. read more

Very reliable and pleasant people to do business with! We had a tricky job where we needed to replace a door with a window. Dimitar pointed out that the look won't be consistent and listed the options for us, one that we could contact the original installer to replace the door, or go with replacing the door and the window next to it. I was impressed by his honesty and his desire to look out for our interests, since none of the other firms giving estimates gave me the name of the company that installed these windows. Dimitar's estimate was extremely good, and he gave us a couple of options of brands to control the cost. Installation was quick and professional, with a few frame fixes and adjustments done well and an outside gate moved per our request at no cost. Thank you! read more

I've replaced my 6 windows with Abstract Windows, and Dimitri (I hope I spelled his name correct) and his team have done great job. Their pricing was very competitive, so initially I wasn't sure for their quality of work, but my concern was groundless. Their installation service was professional with very good finish, and they cleaned-up very well after all the installation. I would definitely work with them again for my future work. read more

Dimitar and his staff were all so professional, considerate and precise in everything they did for me! They are certified by Anderson and other window manufacturers and have all the necessary licenses, insurance and bonding to bring peace of mind. My home is built on landfill in the Foster City area, so there has been a fair amount of settling over the years making it challenging for projects like this since there are no 90 degree corners and straight level walls in the house. They had to work into the evening on a Saturday, no less and then returned on Sunday morning to finish the job, as the storm door ended up being very difficult to fit. The retrofit of the new bay to the overhead eaves and house lines looks like it was originally planned that way. Needless to say, they did the job of a perfectionist and would not relent until it was right and looking like new. It is people like this that built this country and made it great - their hard working, honest and reliable way of doing business is crucial for our recovery and continued success as a nation. read more

Dimitar was recommended by my neighbor and turns out his team did the window replacement for at least nine units in our complex. At that point it was a no-brainer. Communication was great, and he was always flexible with our crazy schedule. It's been a few months now, and the new windows have made a huge difference in our quality of sleep (our bedroom was right on the street). It's warmer now in the winter, and we don't have to hear folks revving their engine at 5 in the morning now. Great job! read more

I recently hired Abstract windows to replace 3 windows in my home in South San Jose. Based on the finished result, I highly recommend Abstract. Dimitar and his crew were professional, showed up on time, worked quickly and efficiently, cleaned up the area when done, and the finish around the windows was complete. I was worried that I would have to repaint or patch around the windows. But they took care of it all. Even details I didn't think about like drainage/etc. Now that they are done I wish I had gone ahead and replaced more of the windows. I will definitely do so in the future and Abstract will be my first call. read more

Thank you Dimitar, Demetrie, and Jose for installing my window and sliding glass door. Demtetrie and Jose did an outstanding job with the installation and removal of the old windows. They were professional, polite, and good to work with. Being in a complex, I need to be mindful of the other neighbors, so I'm happy to say they appreciated, the area being kept clean and nothing blocked the community pathway. I absolutely love my new window and sliding glass door. I'm still getting compliments about the work ethic and quality displayed by Demetrie and Jose. I highly recommend Abstract Windows! read more

Dimitar replaced all the windows in our home in Daly City. He and his team were very professional and did the job in a timely manner. A friend, who owns a highly regarded roofing company, happened to see Dimitar's workmanship and noted that we had found a really competent person. Our painters also made the same observation. Bottom line: after the heavy rains we had this winter, our home is water tight. I would use Dimitar again and have already recommended him to others. read more

My name is Dr. S Johnson. Abstract Windows recently installed new Pella bi-fold patio doors. They were the contractor's for this job and they did an absolutely an amazing job. They were in and out in 3 days. They cleaned up every day, were on time every morning and were very professional. I highly recommend this company and they will be our go-to for windows in the future. Their entire team knew exactly what to do and there were no problems, at all with the installation. read more

We recently had our windows replaced - new construction windows. I was contemplating which contractor to call around the Bay Area. There are so many to choose from. I called a couple contractors and got the estimates and was taking time deciding on which to go with. I was driving down the street from my house one day and saw two houses being worked on at the same time, one had the front sidings replaced, and the other the had the windows replaced. I stopped to asked if they could swing by my house to give me an estimate since I had nothing to lose. That was when I met the owner of Abstract Windows, Dimitar Georgiev. Dimitar came to measure all of my windows and gave me a rough estimate. I asked him to come by the second time to give me a more thorough estimate and asked him to bring by sample windows. He was on time, knowledgeable, courteous and super professional. Even though his estimate was a bit higher than the first two estimates I had, I chose Abstract Windows for the job for two reasons: 1) Dimitar was knowledgeable, honest and professional, 2) he was never pushy and was very patient and taking the time to answer all of our questions, and we had many questions. Needless to say, it's a big job considering how huge my living room windows are. My Milgard Tuscany windows had to be ordered and took a few weeks to come. On the day of the job, Dimitar and his guys came on time, worked fast, cleaned up thoroughly at the end of the day. Dimitar did everything by the books, he pulled the permit, replaced the windows, scheduled inspection, did stucco, and then scheduled the final inspection. Through out the whole process, Dimitar kept me posted of all that was going on. There were no surprises or hidden costs. Dimitar was very upfront, honest and professional, not to mention knowledgeable. I love my new windows, they are beautiful. I would highly recommend Abstract Windows to anyone who needs window replacement. You will not go wrong with Abstract Windows. Thank you, Dimitar! You guys are the best, and you and your guys definitely do high quality work. read more

See all

Dimitar Georgiev and Jose did an excellent job replacing my large front window. I asked Dimitar for an evaluation and estimate because I saw his work on my co-worker's large unique-style dining window. That particular window looks great and the craftsmanship is quite stunning. Dimitar from start to finish was very professional; he was on time for every appointment (when he was delayed once, he called to let me know and arrived on time at the modified time); very informative about the window features and options, answered questions with expertise and accuracy and gave the best suggestion for my needs. When my window was being replaced, Dimitar and Jose explained the plan first, worked diligently with two other gentlemen (sorry, I forgot their names), cleaned everything afterward and inspected the job with me to make sure that it met my expectations. I could not be happier! The windows look wonderful and I have received plenty of compliments on Dimitar's excellent work. I will recommend him with much confidence to my family, friends, and coworkers. Many thanks to Dimitar and his crew at Abstract Windows, D.Marie W. read more

Abstract Windows is a very professional company. They replaced all the windows in my house hassle-free with great product and installation. Their prices are very affordable and they are customer service oriented. I highly recommend them!! read more

Dimitar, Demitri, and their crew just installed 11 Marvin Integrity Wood-Ultrex windows (8 new construction, 3 retrofit) and they did an outstanding job! I had received 4 other bids and his quote was by far the best bang for the buck. These guys arrived early, worked hard, and were professional, clean, and precise throughout the process. They needed no oversight from me whatsoever. Dimitar and Demitri consulted with me about trim size, materials, style options, or anything else a homeowner would want to weigh in on. One of my windows was inside the shower and trimmed with tile. I thought for sure I'd have to hire a handyman later to trim it out properly. Nope, these guys cut the tile and caulked it properly and beautifully. Another window unfortunately had dry rot surrounding it. Dimitar pre-cut the redwood trim for my contractor to put in later and gave me a stucco repair consultation. Lastly, he offered free of charge some sash-lift handles for my double hung windows that we're not included with my window purchase. Home repair is always a nerve wracking experience and you want to know your money is put to good use, as was in this case. I would highly recommend Abstract Windows and would use them again! I'll share photos once my stucco repairs are completed. read more

We recently installed new windows and sills in our home. Dimitar and his crew were amazing! They did a fantastic job and were very reasonable. They stand behind all their work. I highly recommend them. read more
