Our Reviews

The team that did the install was very professional. And the area was always clean and neat throughout the install process. It was the easiest install I have had!

Tom D.

We had damage from a fire and this team had someone on-site the next day. They were professional and experienced. The job was completed in three days, much appreciated effort.

Johnny K.

I highly recommend timeproof. Jordan Filderman took the time to educate us on the different products and services they offer. Jordan made the entire process smooth and stress free. He was extremely professional.

Teja G.

Tyler W came to my home today. He was so delightful to talk to and helpful with all of my questions. If he is anything like the rest of your team, you hire well.

John C.

I called with a question on my roof (they didn't install)and they send someone out right away. Jeff was great. Went on the roof and checked it out. Thanks Jeff!
