Justin was polite, professional, and communicated well today to resolve our window issue. Despite the ball being dropped by previous employees, my experience in this last month has been very positive!

Virgil is what I would call a great representative for lifetime. He was patient and educated me more than I ever expected. I had no idea how complex windows are. I thought a window was a window, it’s not. I feel so much more comfortable about the windows I’m getting from him.

Lifetime installed windows, doors and siding. Installation was quick (42 windows, two oversized glass doors and 1000 sqft of siding. They completed the job in two weeks. Couldn’t be happier with their professionalism and responsive attitude. I highly recommend Lifetime because of their products but most of all for their fantastic employees who are first class craftsmen and craftswomen.
