What clients say

Hear what over 4000 satisfied customers say about us!

We would highly recommend Genex for windows. They were reasonably priced, they were very friendly, and quick and efficient on day of installation. We got told a time and they were here promptly within the time slot they told us. We also had other plans that day and they were very respectful and understanding. Things were done very fast and the quality is top notch!
