Customer Reviews

We’re like you. We look at the 1-star ratings on Amazon to get the real scoop. 

But our customers are busy and don’t have time to log in and review us.  They just shoot us emails, text messages, and handwritten notes, so this is the best we got.

"Lol. I know that you’ll see it through. That’s why I have no trouble recommending you guys. Everyone is great when things go smoothly. The true test of character/quality is how someone responds to challenges."

"We both were very impressed with the project. It had to be a very tough project because of the layout of the roofs, the fact people are living there and the project oversight with Irvine, ABB, etc.

Your foreman, Aurelio Garcia did a stand up job and should be commended. Dan and I had to laugh as he brought his red pen and couldn’t find anything to mark up."
