Replacing condo windows on a busy boulevard in San Francisco is complex with many moving parts. I…read moreoutlined the scope of the job gathering and researching the following entities before committing dollars to the project: Review CC&R Restrictions and getting HOA approval Identifying restrictions and window standards with the San Francisco Planning Department Identifying a Window Vendor with a bonded and insured Licensed Contractor with favorable reviews in the installation of the windows. I gathered quotes from (4) window companies comparing apples to apples after reading every review. What the other companies did not disclose was the complexity of installing fire rate windows except for Deluxe Window. Felix is not just a salesman but one with decades of knowledge and experience in the field. Felix disclosed that I would need scaffolding to install (3) fire rated windows and that the custom order would take 16 weeks for build. Also, that I would need written permission from my neighbor to add the scaffolds to reach my unit on the fourth floor. I appreciated the honesty with potential road blocks that can be resolved and dealt with early on in the project with open communication. None of the other companies that came out to quote me disclosed this information. Deluxe estimates were in line and comparable. Throughout the project, I was in constant communication with Darja who sent email outlining steps to guide me through the process from billing, materials, deadlines and installation. 16 weeks sounds like a long time to build windows but Fyre Tec windows are quality worth the wait. I also went with Anlin single hung windows for the ease of cleaning and life time warranty transfers. My installation took three days to complete with installer George paying close attention to details in water proofing, sealant, foam installation, caulking and trimming the frames. The City Building Inspector signed off to continue work and the second appointment to get final sign off of the permit went through without a hitch. The project was work but Deluxe Windows and the company's competent staff mentioned above help make this into a successful work in progress to final completion. The Deluxe staff were there to answer every and all of my questions. The windows look fabulous and sound proofing has helped minimize the busy street noise.

Once the Windows were built and ready to be installed, the installation manager Lorna was very quick to schedule an installation date and accommodated my scheduling requests. On the installation day, Juanito and Mauricio arrived on time, worked very efficiently and professionally, and did exceptional installation work.

The installers were top-notch--respectful, clean, and clearly took pride in their work. They treated our property like it was their own, which made the whole experience stress-free.

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.

They were also very mindful and respectful of our home throughout the entire installation process. What really stood out was not just the service, but the value. After getting multiple quotes, Window Station offered a more competitive price AND a better-quality product than the others. That combination is hard to beat.

I remodeled my house in 2009 and had Marvin Windows installed at the back of the house, however I…read moredid not replace the windows in the front of the house as they were newer. In 2025, we decided to replace all the windows and the front door in the front of the house and wanted Marvin windows to match the front of the house. There are many window replacement companies out there that will build and install windows for you. However, we specifically wanted Marvin windows and we wanted to upgrade to the higher end Marvin windows as we had installed them in the back. Mark (the estimator) was very responsive and came out to measure and give us an estimate. We signed the contract and he said that we could expect installation in 3 months. Well, 3 months came and went and it seems our custom made windows from Marvin had some manufacturing issue and were delayed. Ok, so instead of a September installation, we were now we are expecting a December installation. It wasn't a big deal except that I had to restore my living room for Thanksgiving. This delay wasn't Window replacement Center issue, it was an issue with the Marvin manufacturing process. So, why am I giving a 5 star review. The installation was great. Oleg (sp?) was the lead installer and he did a wonderful job. My husband (a real DYI person and a perfectionist) even said that the workmanship was perfect. See attached pictures. They were here multiple days and left the rooms cleaner than when they started. Not a speck of dirt or dust was left. So, they only do new window replacement/installation. Meaning if you want a window where a wall exist, they don't do that. They don't fix existing windows (broken glass, old hardware). Mark did walk my husband through how to get a replacement part on another window were the hardware was rusted. They also don't do painting. You need to either paint it yourself on the inside or hire a painter to do this. Also, most of the installers speak very little English. We didn't find that to be an issue. If I had a question that they couldn't answer, they called Mark right away and we were able to work it out. The installers all came on time and there was even a day that I said they had to be done by 5 as we had a dinner engagement and they left when I wanted. Overall, this was a really good experience and I would hire them again to install any windows.
