We love our customers, and it turns out, the feeling is mutual.
Love our new windows! The house is so bright now! The team that did the install were professional and did a great job. Customer service with Performance Windows has been excellent- quick responses to all of our questions and the windows were ready and installed about 3 weeks earlier than we were originally told! I love how easy it is to open and clean the windows and the sliding screens give so much flexibility! Highly recommend!

I absolutely love my new windows! The crew did an amazing job in installation, 12 windows only took half a day! Everything was cleaned up, and Windows look amazing! The quality is wonderful, and I’m anxious to see how they are during the winter time! I love how they look on the outside too, so the finishing touch on the trim, etc. looks really good on the outside of my house! Thank you Performance for a wonderful product, and seamless process!!

The team took the time to walk us through each step, making sure we understood the process and were happy with the progress. We are especially pleased with our new sliding glass door—it looks fantastic and works perfectly. Overall, they did a great job, and we couldn’t be happier with the results. Highly recommend!
