Richard provided an estimate and did a great job discussing the pros and cons of the different options. They were very responsive every time I called for an update on the permitting, and were able to install the roof in a timely manner. Highly recommend.

I am extremely happy I chose Lifetime to install my new shower. Ryan Willis walked me through the process without pressuring me to make quick decisions or purchase something I couldn't afford. Chris, the project manager, made sure things were done correctly while Juan and Juan took care of the demo and install . They all made a good team to give me an absolutely beautiful new shower. Thank you, Lifetime.
