Performance windows did a great job replacing my old rotted windows. They managed to replace 11 in a day wow!. Great customer service would highly recommend.

Team from start to finish delivered as promised. Sales, measurements , installation and followup.  Love the new windows!   Ease in cleaning, screens. Etc.  Guarantee if problems for lifetime is definite plus.

Performance Windows have been amazing to work with while purchasing and installing new windows for our home. Everyone has been professional. The windows look great, and they made sure we were satisfied with the job. Any concerns we had, Kyle from Performance Windows addressed and made sure we were pleased with our new windows.

Performance Windows exceeded our expectations !  The quality of the windows is great and the installation was wonderful.  The install crew was professional, courteous, and efficient. Cleanup at the end of the job was very thorough.  At the end of the project, the project manager followed up in a timely manner and checked every single window to make sure they all worked properly and addressed all of our questions. Overall, an excellent job!

Really happy with the new windows that we got measured and installed for our home. The team did a great job communicating and the install went really well and they were kick to help resolve and issues and make sure the job was done right. Can already tell a difference in temperature with the new windows and appreciate the work they did for us.

We had 23 custom sized windows replaced.  The sales process was simple and straightforward.  The cost and quality were better compared to others.  Then when the installers came, they were on time, polite, extremely efficient and professional and even cleaned up completely after themselves.  We could not be happier with the purchase and installation for this is a real investment in our home.
