The windows were installed yesterday, and it could not have gone better. The team arrived right on time and did a fantastic job. They were efficient, neat, precise, and paid attention to every detail.

The windows look fantastic. The bronze seems a little darker than I remembered, more black, but it works out even better. I am so glad I went with the clear glass and the full thickness. The problem noise is nearly gone (and we had a good test the same afternoon), and dad says he no longer feels any draft. Why did I wait so long? The glass is so clear you don’t know it’s there.

I’d recommend Cityproof to anyone who asks. Thank you, thank you, thank you!

I did want to take a moment to let you know what a terrific job your installers did. I was genuinely impressed with their efforts to get the installation exactly right. It is much appreciated.

Really great work. I built a home studio and needed good soundproofing. Cityproof delivered. Not only do the windows work beautifully (haven’t heard a sound from outside in the middle of NYC since they were installed), the installation crew could not have been more professional or focused on doing a perfect job. Highly recommend them.
