He showed up on time, was meticulous with his measurements, provided competitive pricing, and delivered on everything he promised. He and his team replaced nine different windows and screens for us, and the quality of the work was excellent. The new glass looks flawless and matched the existing windows perfectly. It's refreshing to work with someone who communicates well, does exactly what they say they're going to do, and takes pride in the finished product. I strongly recommend Ram and his team for any window or glass work.

We hired Window Replacement Center to replace two sliding glass doors, and some picture windows…read morewith unusual requirements - one was octagonal-shaped, and two windows met at a corner of the house where there was no structural support. Project manager Mark Kobzanets took careful measurements, suggested options for windows from Milgard and Marvin, and gave us accurate estimates on lead times, especially for the octagonal window which required custom manufacturing work from Marvin. The price quote was competitive with the other companies we had solicited bids from. Mark also worked with the City of San Francisco building department on our behalf to obtain permits and inspections, as well as dealing with the city when some of our style choices were not acceptable with city regulations. For an existing window in need of repair, Mark told us how we could work with Milgard to get it replaced under warranty. Installers Simon and Yuri were very professional. They respected the property during the installation, expertly mounted the windows and doors including adding a structural post to the corner of the house. They also did exquisite craftsman work on the window trim. The windows look great, are quieter, and seal the house better. We are very happy with the results and the experience working with Window Replacement Center. We would hire them again without hesitation.

This is a little odd to say up front with a 5 star review, but we didn't end up having our windows…read moredone by Bestoff. We took over a half-dozen bids for a to-the-studs siding teardown and Hardie board replacement, using the opportunity to replace 21 old single pane windows and two sliding doors with new construction windows & doors. Of everyone we talked to, Sergey was hands down my favorite. If we were just doing with windows, we absolutely would have gone with Bestoff. The only reason we didn't go with Bestoff was out of their control: we ended up going with a singke business that does both siding and windows rather than splitting the work over two contractors. With that out of the way, here's why I liked Sergey so much: He's real. He's not a salesperson. He listens to understand what you want, but he takes pride in his work and he has a perspective (that he'll share with you) on what to do with your windows to bring out the best in your home. Most folks who came out just asked us if we wanted to keep our sliders in the same configuration. Sergey was the only one who went through each room, truly thought about the air flow and the aesthetics, and provided recommendations on each configuration. He acknowledged it was free advice, and it was -- we're going to follow his recommendations because they make sense, even though we never would have considered them before (and nobody else suggested them). And because Sergey takes pride in the outcome of his work, and not on his upsells, he never pressured me into any unnecessary frills. In fact, any time I considered a "premium" upgrade option, Sergey talked me down and explained why I didn't need it. For example, my head started spinning over energy efficiency and fire protection. I was debating SunMatrix/Quadratherm it's SunShield/Quadratherm for our south and west windows. Sergey was the only bidder to really take me through the pros and cons and ultimately make the case that, for this project, I shouldn't bother. Similarly, I emailed about WUI-compliant tempered gas after I realized I'm only 3 houses away from a high fire danger zone. I waited to know if it was worth getting the WUI glass. Sergey was the only bidder to go over the pros and cons in detail and explain why it would be an unnecessary expense for us. When when I let Sergey know we chose to go with a combined siding/windows contractor, he gave us even more advice on things to look out for to protect ourselves. If you're looking to do a substantial window project, give Sergey a call. I'm trying to manage my deep regret at not getting to work with Sergey. I'll feel a little better if I can imagine playing even a small part in another family getting to work with him
