Fire Alarm Electricians

The electricians we work with handle the full range: testing and replacing hardwired smoke and carbon monoxide detectors, repairing or extending interconnect wiring, diagnosing false alarms and persistent chirps, and integrating hardwired units with battery backups. Whether you need a single detector swapped or the whole interconnected system restored, you're matched with a pro who does this work regularly.

Swapping a battery is fine on your own, but hardwired detectors, interconnect wiring, and any unit that keeps false-tripping call for a licensed electrician. These alarms tie into your home's wiring and into each other, so a wrong connection means a detector that fails silently when it matters most. A pro tests the full system and confirms every unit sounds together, which is the part you can't verify with a screwdriver.

Cost comes down to how many detectors you have, whether the units are hardwired or interconnected, and if the wiring needs repair or extension. A straightforward hardwired detector replacement usually runs about $120 to $250 per unit installed, while wiring repairs or a full interconnected system across a home can land between $400 and $1,200 or more. Your electrician gives you a clear price after testing the system.
