I had two very large windows replaced by Lifetime. I was very pleased with their contractors - they were on time, cleaned up their work space perfectly, and performed a job well done. Mr. Hector Pena, project manager for Lifetime, came by and checked out the project. He made a couple of adjustments and made sure I was very satisfied with the work done.

We hired Life Time to convert. Our kids bathtub into a standup shower. Moe and Luis were incredible, very respectful of the home and didn’t leave a speck of dust. The finished product is beautiful and we couldn’t be any happier!
