 Trustindex verifies that the original source of the review is Google. Great experience with CalFoam on our cabin project! They used closed cell spray foam to provide a permanent air seal and moisture barrier in a tight space. The added sound proofing is a huge plus, and the cabin stays at a constant temperature. If you want the top current insulation for any build, give these guys a call!

 Trustindex verifies that the original source of the review is Google. This company lives up to its 5 Star review. I had a terrible rodent problem in the underside of my older mobile home. It had become a haven for rodents living in the insulation between the vapor barrier and subfloor. It was (from my point of view) a job from hell; not to mention the smell,  the jagged serpentine rocks to navigate over and the slope of the land that minimized head space for half of access to the underneath of the mobile. Despite those deterrents Cal Foam Dereck Chester maintained a positive, personable attitude. In a timely manner all the old nasty insulation and vapor barrier were removed and taken away. The real gem of service is post underbelly renewal. The entire sub floor and cross supports are encased in a glacier looking foam material that will not melt. Haha. Actually it is a very hard material thick enough to insulate, but shallow enough for no burrowing! The finished product looks like hell frozen over and to me (I’ve been battling rodents for years and been down below many times) that’s what it is! Hell frozen over and I thank Cal Foam. You will be pleased with this company. They are reliable, responsible and provide excellent service!

 Trustindex verifies that the original source of the review is Google. Cal foam is a group of hard working brothers. They recently came to spray my house masked everything up and cleaned up really well after themselves. Spray was neatly installed and looked very professional. Would highly recommend for any spray insulation needs. They’re not afraid to travel either!
