What Smoke Detector Installation & Repair Involves
We install 100% hardwired 120V combo smoke and carbon monoxide detectors with 10-year battery backup, interconnected so that if one alarm goes off, they all do, either through 3-conductor wire or a CSFM-approved wireless mesh system for retrofits where running new wire isn’t practical.
On the repair side, most calls we get are for a detector that’s beeping and won’t stop, which is often a fast, inexpensive fix rather than a full replacement.
Signs You Need Smoke Detector Service
A detector is beeping or chirping intermittently and won't stop
A detector is more than 10 years old, smoke detectors have a real expiration date
A required room is missing a detector
Your detectors aren't interconnected, so only the alarming unit sounds
You're renovating and need updated detector placement to meet current code
Your home doesn't have combined smoke and carbon monoxide detection
A single beeping detector is usually a quick fix, but missing coverage, no interconnection, or units over 10 years old are worth scheduling service for.
Why Is My Smoke Detector Beeping?
The beeping pattern is usually a real clue to the cause:
What You're Hearing
Likely Cause
What to Do
One chirp every 30-60 seconds
Low backup battery, even on hardwired units.
Replace the backup battery first; if it keeps chirping, the unit itself may need replacing.
Continuous or repeated beeping with no clear pattern
Dust, humidity, or a sensor nearing end of life.
Clean the unit; if it persists, it likely needs professional service or replacement.
Beeping that started after a power outage or electrical work
An interconnect wiring issue, or a unit that lost its signal to the others.
Worth a professional check, especially on hardwired interconnected systems.
A Beeping Detector Doesn't Always Mean Something's Broken
Most beeping is just a low battery, not a sign your whole system has failed, and it’s usually a quick fix rather than a full replacement. That said, persistent beeping across multiple units, or any detector older than 10 years, is worth a professional look, since smoke detectors genuinely do expire and stop performing reliably even if they still make noise.
If you’re not sure which situation you’re in, describing what you’re hearing when you call usually helps us tell you over the phone before we even come out.
Our Smoke Detector Service Process
1
Assess Existing Detectors
We check age, type, and condition of every detector in the home.
2
Replace or Add Hardwired Units
We install new hardwired combo smoke/CO detectors where needed.
3
Interconnect & Wire
We wire or configure detectors to interconnect, so every unit sounds together.
4
Test Every Unit
We test each detector individually and as an interconnected system before we leave.
Permits for Smoke Detector Work: A permit typically isn’t required for like-for-like detector replacement. Adding new hardwired detectors as part of a renovation may require one, and we’ll confirm this based on your specific project.
What Affects Smoke Detector Pricing
Pricing depends on whether the visit is a beeping repair, a like-for-like replacement, or adding new hardwired units.
California code requires hardwired smoke detectors with battery backup in most homes, not battery-only units. Hardwired detectors are powered by your home’s electrical system and interconnected, so every alarm sounds together, with the battery serving only as backup during a power outage. Battery-only detectors don’t meet this standard and are a common finding during our safety inspections of older homes.

Frequently Asked Questions
Why is my smoke detector beeping?
Most often it’s a low backup battery. If replacing the battery doesn’t stop it, or the unit is over 10 years old, it likely needs professional service.
How many smoke detectors does my home need?
California code generally requires one in every bedroom, outside each sleeping area, and on every level of the home. We’ll confirm exact placement for your specific home.
Do smoke detectors expire?
Yes, typically after 10 years, even if they still appear to work. The manufacture date is usually printed on the back of the unit.
Can you fix a beeping detector without replacing it?
Often, yes, if it’s a battery or interconnect issue. If the unit itself has reached the end of its service life, replacement is the safer fix.
