"You have a 5-star rating from your recent customers, Gordon and Christine W. You and your workmen, Phil, Larry, and Richard, were courteous, friendly, and above all, gave excellent performance from start to finish. We returned home yesterday after doing errands...around 4:00pm... was quite hot outside so it was great to come into the house and feel the cool air :-) the upper floor air is fantastic! Thanks for all your hard work and dedication to the job."
"Dear Mr. Morris,
Thank you for the quick response to our concern with one part of the gutter work done this past September. Jose came to our home yesterday, and apparently solved the problem by modifying one downspout.
We appreciate the professional attitude – good prompt service with needed repairs – that distinguishes your company."
-Robert, Sebastopol Homeowner
"I wanted to take the time to thank you again for your help and prompt work for us. It was a last-minute job and we are very grateful that you were able to fit us in. The sheet metal looks great and we started our machines on schedule thanks to you."
