We really enjoyed working with Performance Windows. Our house is much more efficient now, and quiet! We no longer hear the dogs barking behind our house at 5am, yay! These windows are easy to open, easy to clean, and I like the built in safety features. They did have to come back, to do a little touch up work to the exterior of the house, but they came the next business day. We could only afford to get half of our windows replaced. If you look at the 3rd picture, you can see the difference in our new windows, versus the original to the house windows. They did guarantee these prices for 3 years, so hopefully next year, we can replace the remaining windows.

We had all 13 windows replaced from the original builder grade that were on the house. The process was very easy from the original measure of the windows through the install. The install was very fast and professional – they were done in less than a day and they look fantastic

We had a wonderful experience with Performance Windows from start to finish. The entire process took about six weeks from our initial consultation to installation, and everything was well organized with great communication throughout. The team was knowledgeable, never pushy, and took the time to answer all of our questions so we felt confident in our decision.

I recently had Performance Windows replace every window (20+) and sliding door in my house, and they did an absolutely fantastic job. The windows themselves are of great quality, and I am already loving the upgraded functionality—especially how incredibly easy they are to clean!
