Insulation Services for Mill Valley Homes & Businesses

Mill Valley's building stock — Redwood-canyon homes and hillside custom builds — comes with its own insulation challenges. Shaded, damp lots where closed-cell foam prevents mold and rot. USA Spray Me has been insulating Bay Area properties since 2015, and our spray rigs are in North Bay & Wine Country every week.

Because Mill Valley is in California Energy Code Climate Zone 3 (cool, foggy coastal), we size every job to the prescriptive R-values and air-sealing requirements of Title 24, Part 6 — so your permit passes the first time and your utility bills drop for decades.
