about us


Lifetime service

At Performance Windows we pride ourselves on the quality of our windows and of our service, with each of our installers having installed thousands of Alside windows and working exclusively for Performance. Additionally, each of our installed windows comes with two warranties. The LIFETIME LIMITED WARRANTY covers any damages or changes to the window, it's frame, or to the installation for as long as you live in your home. This is also transferable to any other owner in the case of a sale of your home if the sale occurs within the first ten years of installation.

In addition, all windows will also come with the Alside Glass Breakage Warranty which will cover accidental breakage or cracks. These warranties are included in every window that is installed by a Performance Window. For any additional questions feel free to fill out the form below and submit.


At Performance Windows we pride ourselves in having the best windows, the best installers and the best service in the American Mountain West and South. Our Team has decades of combined experience and have worked to install the highest quality windows for thousands of homes. Whether your goal is to improve your home's energy-efficiency, aesthetic, or security, Performance can deliver.
