Thank you to the Performance team for replacing the windows in our Newcastle home. From the initial consultation and outlining of their program to the scheduling, installation, and cleanup, they did a fantastic job. We highly recommend Performance Windows!

Absolutely thrilled with our new windows! Excellent service and quality. Five stars for honest pricing, great communication, and a noticeable boost in comfort and curb appeal!

I had 6 windows replaced by Performance Windows recently, their crew did a fantastic job and they were very quick as well. It’s nice to be able look out my windows and not see anymore condensation. I’d highly recommend Performance Windows if you’re thinking about doing window replacements!

We recently had our windows replaced and Performance Windows did a great job.  They arrived as scheduled, completed the work as promised and left my house cleaner than when they arrived.  I noticed an immediate improvement in the sound level and can’t wait to see the improvement in our utility bills.  I would definitely recommend them for both quality of product and quality of service.

Recently I had the front windows in my home replaced by Performance Windows. They completed the job in a timely and professional manner. They look great and updated the look of my home. If you are considering replacing your windows I highly recommend Performance Windows.
