Your Local Fire &
Security Experts.
Major Alarm has protected North Bay homes and businesses since 2005. We answer our own phones, show up when we say we will, and treat every job like it’s our own building.
What We Do Best
Simple systems. Honest prices. Local people who pick up the phone.
Fire Alarms
Design, installation, and service of code-compliant fire alarm systems for commercial and residential properties, plus NFPA 72 annual inspections that we track for you. Let us manage your system so you don’t have to.
Security Systems
Burglary and intrusion systems for businesses and homes, with integrated solutions that keep you safe without giving you more to think about.
Monitoring
Round-the-clock central station monitoring. Let us replace your expensive, failing POTS lines with robust, NFPA 72-approved cellular communicators.
Apartment and HOA Services
We track, coordinate, and facilitate annual inspections and repair work across large apartment complexes and HOAs, so property managers have one number to call.
Why Our Neighbors Choose Major Alarm
We’re not a national franchise with a call center. We’re a small, locally owned business, and we treat your property the way we’d want ours treated.
You’ll talk to the same people every time
No call centers. Your technician knows your name, your system, and your building.
Honest quotes with nothing hidden
We tell you what you actually need, not everything we could sell you. Every quote is in writing.
Repair first, replace only when we must
We’re industry leaders at fixing existing systems, including the problems other companies couldn’t solve.
Locally owned since 2005
We built this business on referrals across Sonoma, Marin, Napa, and Solano. Every job is our reputation on the line.

Your Questions, Answered
Can’t find your answer here? Just call us. We’re real people.
How quickly can you give me a quote?
Most quotes go out shortly after a site visit. For smaller jobs we can often give you a ballpark over the phone before we even come out.
What happens when my alarm goes off at 2am?
Our central station contacts you immediately, then dispatches police or fire if needed. You can give us a list of contacts to try before emergency services are called. That’s entirely up to you.
Can you service a system another company installed?
Yes. We service systems of every size and can take over monitoring and maintenance on existing equipment. We specialize in repairing systems that other companies said had to be replaced.
Do you still support POTS phone lines?
We can, but we’d rather get you off them. Copper lines are being retired and rates keep climbing, so we replace failing POTS lines with robust, NFPA 72-approved cellular communicators.
