Our Customers Say it Best

"Thank you so much for putting together such an awesome team and being a great company to work with. I've struggled to find good contractors with virtually all other home renovationprojects, so your really good company and experiences really stand out."
Matt Farnham, Santa Rosa
"The installers were incredible. They arrived on time and went right to work. They told us what would be done and then installed a new system and repaired or replaced many of our old ducts and registers. At the end of the job, everything was cleaned up, and old parts were removed. They installed a new Carrier variable-speed air conditioner and heat pump. We have quite improved circulation throughout the house. Great work!"
 Michael D., San Francisco
All of the guys who work for Simpson were kind, gracious, efficient and patient with my questions. Bernie and I handled the ethernet switch and WIFI setup seamlessly. We were up and running by the end of yet another hot day. I have nothing but great things to say about Simpson Sheet Metal, not the least of which is that they do what they say they will do, at the price they say they will do it.
