We hired Lifetime Home Remodeling to replace our siding and are very pleased with the final product. From Dee the salesperson, to Allen the project manager and the crew of BBB. They were on time, cleaned up every day and our new siding looks great! We would use Lifetime again for another home project.

Fantastic company! I had three windows and a patio sliding glass door replaced. From Sales Rep Paul to Installers Tim and Daniel, I found the process and information and work to be exceptional!
