A door I had installed a while back had a trim piece that had come lose. I contacted Lifetime and as expected, they immediately set up service to have the door repaired. The technician, Darian M. showed up and repaired the door without issue. The repair was not rushed and looked as good as new. A big thank you to Darian and all of the Lifetime crew. A++

Lifetime resided our house using James Hardy siding. Jason D., our project manager, was extremely responsive and professional. He addressed our concerns immediately and ensured we were satisfied with the outcome

These people came out gave me a quote had me fill out an app just to send me a letter of denial. So I call them back to tell them I NEVER need the credit app I have the 70k cash. They then said they would call me back and I'm still waiting 2 months later. With no call. Poor customer service. I guess they want me to beg them to take me cash. Not gonna happen.
