Worked with Lifetime Windows 2 years ago replacing 9 windows and a slider. Had them back this month to do remaining 5 windows, and Lifetime did not disappoint. These folks are great to work with. The installation was smooth, and they left my place clean. Very respectful. Sales worked with me to get best solution at a price I could afford. And when personal issues forced me to reschedule my install, Lifetime was supportive and accommodating. A good company to work with.

Every person that I dealt with at Lifetime was extremely professional, and they are heads above their competitors. My project managers, Jason, Justin and Kevin, the office staff and the installers did an excellent job. I am extremely satisfied with the workmanship, and my 45 year old house looks TERRIFIC and Brand New. Also a thank you to Rebecca for her assistance as well. Thank You All!
