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 cannot thank you enough for stepping in, on Tony’s recommendation and handling our newly coated roofing project in Menlo Park so smoothly and masterfully…We look forward to [indecipherable] and referring you without further reservation.”

"Bill D[...] always put the customers first always willing to go beyond the normal to assist us."
Lawrence Stauffer
Building Owner
"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."

"The foreman had the greatest attitude. He went above and beyond."
