This is a bit of a late review, but better late than never. We hired Abstract Windows to install new James Hardie siding on our house and to replace a standard door with a beautiful sliding door leading to our deck. From start to finish, Dimitri and his team were outstanding. They were professional, reliable, punctual, and highly skilled. They always arrived on time, kept the work area clean, and consistently provided updates on the project's progress. Communication was excellent throughout the entire process, which gave us a lot of confidence and peace of mind. The quality of their workmanship exceeded our expectations, and it was clear that they take great pride in what they do. Finding contractors who are honest, trustworthy, responsive, and dependable can be challenging, but Dimitri and his team truly stand out. We couldn't be happier with the results and would not hesitate to recommend Abstract Windows to anyone looking for high-quality work and exceptional customer service. It's rare to find a contractor this professional and reliable these days. Highly recommended! read more

Dimitar and Abstract Windows are great. We hired them to install multiple doors in our home. They came to our home, measured, and quoted. When it came time to install the doors, their installation team was on top of everything. The doors look great, and we're very happy. I am happy to recommend them, and we would definitely use them again. read more

I had a very good experience with Dimitar and his team. The Window installation process went very smoothly, and Dimitar was very responsive regarding the estimate and installation of the windows. I also think they're very competitively priced. I recommend them for your window installation without hesitation. read more

Overall great experience working with Dimitar and Ignacio. It all started with requesting a quote to replace a large window on my house. Given their expertise of working with Pella I chose them over other contractors. Ignacio showed up for the initial measurement and was very professional. They helped pick up the window from the warehouse (it was a large 8' x 8' window) which saved me a lot of hassle. Their quote was slightly higher than others but I still decided to go with them as they appeared to be very good at communication and it was clear they know what they are doing. They finished the job in a day and were extremely efficient and clean. They had to set up scaffolding and all that. My window was wood on wood and I wish they would have offered painting as well which wasn't the case. Overall, I'm pretty happy with the outcome and recommend them to others as well. read more

Overall I had a great experience. I called in to get a quote on one window. Dmitry came out to check out my request and he suggested some window options for me. I'm glad he recommended to get a Pella window to match the rest of my house. I was tempted to go with Milgard, but decided on Pella. It took a little over a month to get my window due to the holidays. For the installation the team came out and helped explain the process. It took them about an hour or so and they did a great job. They covered the area to keep it clean and installed with window. They provided a great experience with little stress. I'm happy that I went with them. read more

Highly recommend and would hire again! Dimitar and his team are very professional and communicative. The window replacements were completed as planned with very good quality. Thanks for the great job! read more

I had an old Gothic style arch window that needed replacing. Several vendors would not work with me on this because they said it was too difficult to order and make these windows. I found Abstract Windows and they came out did measurements and gave me a bid for a new window. Took about eight or nine weeks to order as this is a custom item and installed it in one day. It looks absolutely fantastic and the finish work was great. read more

Dimitar guided me through the entire process of selecting my two Andersen doors. He was extremely patient and took the extra effort to ensure all measurements were correct before placing my order. Communication throughout the installation process was excellent. His crew was detailed, professional, and took the time to properly prepare the rooms before installation. It was one of the cleanest installations I've ever experienced with a contractor. I would highly recommend Abstract Windows for any future window or door installation projects. They deserve an A++++ rating! read more

This was one of the few great companies that had submitted bids for the project. Dimitra was on time and took the time to explain the project process. Unfortunately, I had to go with another contractor for the job. Thank you for your time and patience in responding to my request. Pal read more

From start to finish, the process was smooth and professional. Ignacio was our first point of contact and did an excellent job answering all of our questions. He walked us through different window styles and types and provided multiple quote options so we could compare and choose what worked best for our home and budget. Dimitar came out to take measurements, and once everything was finalized, we signed with Abstract. There was one small hiccup when our initial installation date was accidentally missed, but the team was responsive and rescheduled quickly without any hassle. The installation itself was estimated to take two days, but the crew completed everything in just one day. They worked efficiently and left the space very clean. Afterward, another Dimitar followed up to ensure we were completely satisfied, which we really appreciated. We've had the new windows for several months now, and we love them. Overall, a great experience and we'd recommend Abstract Windows. read more

Dimitar and his crew did an excellent job in replacing some very old windows in our oceanside house. His crew also did the framing for 2 windows in a completely new location by the Fireplace, this really opened up this central room with daylight and just transformed it, I love the work they did. The only hiccup was some manufacturing issues with 2 of the windows, but Dimitar acted in the most professional manner and got then replaced and re-installed. Overall excellent work from Dimitar and his crew, I highly recommend them for any window or siding work, notch! read more

Abstract Windows - New Windows - Windows Installation Near Me - San Carlos, California

Dimitar and his team did an incredible job in just 1 day! 10 replacement windows and the quality of the work is fantastic! I highly recommend Abstract Windows. read more

Abstract Windows replaced all the windows in our home - 17 in total - as well as the front siding on our second story. They did a great job helping us select windows to minimize noise on a busy street, and the crew that installed the windows, siding, and trim did a great job! We're super happy with the results. This should be five stars, no? The problem was persistent, poor communication and project management throughout. We needed to coordinate window install with scaffolding and painting, which Abstract Windows knew when we signed the quote and we reemphasized while waiting for the windows to come in. We didn't hear anything until the day before they wanted to install, then had to scramble. They were unclear about payment timelines and amounts, failed to let us know that a mid-project inspection would need to happen, and didn't schedule the inspection until the work was done, resulting in a three-day delay for the other contractors. If they had communicated clearly about timelines and inspections, provided itemized invoices, and kept things moving smoothly, this EASILY could have been a five star job. If you have anything more complicated than a simple window replacement, be prepared to do a lot of project management. read more

Great and friendly customer service. No pressure, no hassle. Dimitar was able to answer all my questions and provided solutions to my needs Highly recommended. read more

Dimitar and his team are top tier! They have been professional the whole way through. Their pricing was by far the best quote around and they delivered excellent work. If you're reading these reviews, don't hesitate to go with Abstract Windows, you will not be disappointed. read more

Abstract windows replaced our kitchen window and also fixed our front door (added new hardware and adjusted it so it smoothly opened ... previously it was jammed and hard to open). Everyone on the Abstract team was extremely professional and very responsive. Upfront, they gave us great advice on our options and a very reasonable price (I had reached out to several contractors). We can't recommend them enough ... great customer service. read more

I used Abstract Windows to do a retrofit replacement from the original 30yr old aluminum windows to new fiberglass windows from Milgard. Alessandro came out and reviewed all windows and happily answered all my questions. For the final measurement Dimitar and Alessandro explained that 2 large windows couldn't be done as retrofit and let me easily remove that from quote since I didn't want new construction right now. Their pricing was very competitive. The windows were ready when the said and they installed 11 windows in 1/2 day. Everything was so professional and now the house is so much quieter that we cannot hear when the delivery truck pulls up for packages. So nice. Windows look great and modern. I highly recommend using them for replacing windows. read more

The best contractor I've worked with so far in the Bay Area, there's a reason why this company is Diamond certified. Dimitar, owner, went above and beyond to ensure I was happy with the installation and most importantly, making sure all work was done properly to pass inspection. Our city inspectors tend to overpick and make things difficult for contractors so I really appreciate Dimitars patience in this whole process. My new Milgard windows are great, and I couldn't be happier with the whole experience with this company. Highly recommend Abstract windows if you need new windows for your home. read more

Abstract Windows replaced four aluminum framed windows with Milgard vinyl windows. The service was professional and efficient from the estimate through the installation. Have already recommended them to friends and will definitely use them again in the future! read more

Dmitar is as good as his reviews. Quality honest businessman who does great work (he's done windows for me twice). Price is good and he has options for various levels of window (pricing levels). Highly recommend. For one of my jobs, he was fixing a prior bad job by someone recommended by Ashby lumber. Sucked for me but was good to meet Dmitar and know my window needs are forever handled (until he retires!) (Diamond Certified if that matters to you. It's not easy to become DC, means something.) read more

Amazing local company! Owner Dimitar is kind, knowledgeable, and goes the extra mile. His crew members are hard working, efficient and tidy. When we later noticed a subtle streak in the glass of the Milgard windows days after the job had been completed and paid for, Dimitar came back out to carefully check all the new windows again w us and found another subtle one in a different window glass. Milgard window expert reviewed after we filed a claim w Dimitars help and they agreed when they came out the double pane glass had somehow been "flipped" in manufacture (not common but can happen in the way double pane windows are constructed we learned) and Milgard replaced with correctly sealed glass. The windows and sliding door have lifetime warranty so that was also a selling point for us. They all look and work great now. Abstract/Dimitar provided us exceptional window and sliding door installation/replacement at a competitive price. Highly recommend them! read more

Dimitar at Abstract Windows was highly recommended by a neighbor who had Abstract Windows replace all their windows and sliding glass doors. This winter, I relied on Dimitar to replace a tricky awning window in my second-story master bathroom. He was able to match the windows required by the HOA, and his installation was done right. This Spring, the lock on my Milgard Patio sliding glass door broke. Replacing the door would cost about $4,000. Getting exactly the right locking parts and screws from a Milgard parts catalog was not easy. Dimitar persisted. One month later, Dimitar arrived with exactly the right parts and was able to install the new locking handle and screws in 15 minutes. I highly recommend Dimitar and Abstract Windows. read more

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

Dimitar and his crew installed our new Pella windows we purchased by Lowe's. They were great! They were very good at communicating with us, professional, knowledgeable, and showed pride of their craftsmanship. They did their job well, on time, and cleanly. Over the years, we redid all our windows through Lowe's and Abstract Windows were by far the best of all the installers! read more

I had a fantastic experience with this contractor. I needed five windows and a new patio door installed. Dimitar and his crew completed the job on-time and on-budget. Their workmanship was excellent and they paid attention to even the smallest detail. The communication was very good and Dimitar is a very straightforward dealer. He is very honest and up front. I will definitely use them again and would recommend them without hesitation. read more

5 stars are not enough to describe my satisfaction of the services they are providing! Very quick response, complete quote including best cost vs. quality analysis, fast material delivery followed by quick quality work... Clean and shine after work is done. They're leaving to the owner nothing to worry about! Only to enjoy the perfect result of their work... Great job Mitko & Mitko! Thank you so much! Nikolay K. read more

I would highly recommend Abstract Windows. I replaced sliding doors with a French door. Dimitar responded to my call very quickly and came to my house to evaluate the project. He was very informative and went through the measurements of the door and was very thorough on what the Job entailed. On the day of installation, his team did a great job all the way. They left the area very clean and the quality of their work was great. read more

We hired Abstract Windows this past August. My wife and I thought they would be expensive (as they're a subcontractor for Andersen Replacement Windows). Dimitar (owner) came in with a great bid. He was honest, straightforward and we felt he and his team would be a good choice. We had only one, 20 year old leaky window to replace and they took care of it in just a few hours and now it meets code! Dimitar and his team (George and associate) gave us a bigger window, new sill, patched and matched our 50 year old stucco pattern and did a great job cleaning up! Absolutely we'd recommend Abstract Windows! read more

Contacted Abstract after a recent window installation from another company went totally awry. Spoke with Dimitar on the phone and explained my situation and was looking for a second opinion on the installation. Without hesitation, Dimitar offered to come by my house on his way home after work and look at the other company's installation and offer me suggestions. He knew full well his visit wasn't going to generate revenue for him but came by anyway and gave me a bunch of things to think about. He is super knowledgeable, kind, and someone who in hindsight, had I known about him, would have been great to work with on my window project. Strongly recommend if you are looking for new windows that he be your first stop! read more

I found these guys as sun contractors through Lowes. They did and excellent job installing new windows and sliding glass door in my 1950s construction Bernal Heights home. Initial installation was professional and punctual and they even spent considerable time troubleshooting a leak on the sliding glass door several years later. I cannot recommend them highly enough! read more

I regret to write that my experiences have been sub-par. I had a number of Milgard windows for the front of my home ordered through Lowes. Dimitar reported for the first round. The windows frames were not even, so I had to deal with Milgard and resolved under warranty - total time spent waiting for order to be complete: 3 months - $12,000.00 worth of windows: My second experience was very bad. I made an additional large Milgard window order for the back of my home, and Dimitar came to measure and instead of being professional and courteous, he was rude and dismissive with my 72 year old mother. I was very disappointed that he conducted himself in a way that made her feel terrible, so I called him to ask why: in turn, he insulted my mother, used profanity and told me that he didn't want my business. Wow, the order was going through Lowes again, and he was simply there to measure and install. He created a very big mess for me, and set me back weeks on my project. In addition to this review, I have filed a formal complaint with Milgard, and Lowes, and am working on my next complaints to the BBC and State of California. Dimitar simply should not be working directly with customers, especially elderly people. With as many local options available, I had no choice but to cancel my order with Lowes and go with another window company, that actually saved me $1000.00! Dimitar may have done me a favor by being rude, but it still does not constitute more than one star. Thank you for reading, and good luck in your search for QUALITY WORK AND GOOD CUSTOMER SERVICE. read more

Used these guys to install a retrofit patio door. Wow, awesome job in about ~2.5 hours or so. A team of 3 showed up on time, removed the old door, & installed the new door in a very professional manner. The install came out better than before, as the team sealed every area where outside air could leak into. Great company to work with, and recommended for any outside door jobs! read more

Excellent service and great quality. I had experience with Abstract Windows twice now in 2023-2024. First project was through Home Depot that subcontracted them. Then I used them for a residential home project that required a custom window that was outside the scope for Home Depot. Both times went well. They are on time, respectful workers and knowledgeable. They only use quality products and have incredible attention to detail. Definitely would use them for any future need too! read more

In the middle of COVID, my wife and I bought a fixer upper. Dimitar and his team replaced approximately 30 windows and 2 large sliding doors in the home. I am extremely happy with the work they did and their customer service. They did an excellent job installing the windows and doors. His crew was efficient and clearly communicated how the installation process was going. Dimitar himself was patient, explaining the process and what to expect during installation. He also facilitated the permitting process for us. A month after installation, one of the balancers on the window failed. Dimitar came to my home and fixed it immediately, instead of having to wait on the manufacturer warranty. I highly recommend abstract windows. read more

Excellent service, quality and punctuality. Abstract Windows did a retrofit installation to our apartment window a few years back and we decided to get a bid from them for our new home construction's windows and doors and ended up choosing them for the project. That turned out to be an excellent choice! Dimitar brought his expertise and knowledge to the job from day one and he took the time to explain to us all available options and to highlight the pros and cons of each one. His crew was very professional and everything was done timely and in a clean fashion. Their trucks were always parked properly on the street and did not block crosswalks or traffic, unlike other crews who worked on this home construction. As in my previous experience with them, I can only think of positive things to say of Dimitar and Abstract Windows. They're by far the best contractor I've dealt with ever! Keep up the great job guys! read more

The house looks brilliant. Windows and finish looks superb. Dimitar and teams were thoughtful, tidy, and cleaned the job site up thoroughly. Dimitar and team have just finished their second job at our home. It was a large job done over two periods (our choice). Our home is on a steep block surrounded by trees. We had the following work completed: *1 x large sliding doors *1 x front door *10 x windows They removed all old windows and disposed of them. They installed all new windows, installed screens where needed, fixed all drywall (we chose frameless windows so we would achieve a cleaner overall look - more finishing work for Dimitar's team), and thoroughly cleaned all areas upon completion. My suggestion would be to come to Dimitar's team first before you go to a big window company. They directly install all the big brands. A pleasure. read more

I can't recommend Abstract Windows enough. Dimitar and his crew helped us pick out and replace 15+ rotted windows in our house that had previously been vacant for 17 years. Needless to say, the new windows are a tremendous upgrade from the single pane windows that we had before. We are incredibly happy with the results. The install itself was on time and well done. Great company to work with. read more
