Where We Work
Sonoma, Marin, Napa and Solano counties are our primary service areas, worked from one office in Petaluma.
Major Alarm covers Sonoma, Marin, Napa and Solano counties as primary service areas. Everything is run from our office at 1160 Industrial Ave, Ste G, Petaluma, CA 94952, by the same technicians and the same central station wherever the job is.
We also take work north of Ukiah and in the East Bay on a case-by-case basis. Ask, and we will tell you honestly whether we are the right fit for the property.
