Smoke Alarm Installation

It covers everything from replacing expired or failing units to installing new hardwired detectors with battery backup and wiring an interconnected system so a single trigger sounds every alarm. The electricians in our network also add combination smoke-and-CO units, place each detector to code, and test the full setup before wrapping up.

Swapping a battery is easy enough on your own, but hardwiring and interconnecting detectors ties into your home's wiring and has to meet code. A licensed electrician handles the wiring safely, gets placement and spacing right, and verifies every alarm responds across the system, which is what real protection requires.

The main factors are the number of detectors, whether they're hardwired or interconnected, and the unit type, such as a standard smoke alarm versus a smoke-and-CO combo. A single hardwired replacement generally runs about $100 to $250, and wiring an interconnected system through a home typically falls between $400 and $1,200.
