Had all of our windows replaced as well as two sliding glass doors. The quality of the windows and doors is amazing, we were replacing old vinyl windows which were peeling off on outside. Dante and John did a great job with installation. Tje stucco company did a wonderful job too.

Lifetime Bath & Shower is a wonderful company. Stephan did a great job on the installation of my shower. He did the job in 2 days as promised and it looks just as I imagined. Gabe and Chris were the best to work with too. I would work with this company again in the future.
