Knoxville, TN

Performance Windows provided a premium product at a reasonable price. They arrived promptly, as promised, gave us an efficient, quality installation. From beginning to end (sales to cleanup), our experience was a 10 out of 10. We would recommend both the company and the product to anyone.

We feel really good about our new windows. We love how they work– very smooth and easy–how they look inside and outside. Performance Windows did a great job of showing us how they operate. The installation crew did a great job.

We chose performance windows because the windows were far superior to anything else we’ve seen. They are beautiful in appearance and insulated to reduce the effects of outside heat and cold. We really love the ease of opening and closing them and they have a unique double-hung folding feature for ease of cleaning. We would recommend these windows to anyone.

I am glad to have chosen Performance Windows. The install team was very respectful and they did a fantastic job. The windows look great and the price was very reasonable.

We were very pleased with the sales ordering and installation process. The crew was very efficient and respectful. Due to the amount of windows, it was a two day process, but each time the crew cleaned up after themselves perfectly. We couldn’t be happier with the way the windows look on our home. They’re so easy to open and close, and I know they’ll be so much easier to keep clean.

We chose Performance Windows because they seemed a very good quality, will not rot, plus the pricing was good compared to the competition. Installation of 37 windows took 2 days. The installers were efficient, hard working and showed up on time. We are pleased with the final result and would recommend this company.
