Smoke Detector Installation
Quick answer
Hardwired, interconnected smoke detectors installed to code, every bedroom, hallway, and level, typically $100–$250 per detector or $400–$1,200 whole-home, including 10-year sealed or smart units.Typical installed cost: $100–$250
Code is specific for good reason: detectors in every bedroom, outside each sleeping area, on every level, all interconnected so one alarm sounds them all. We install hardwired systems with battery backup, including smart detectors that alert your phone and silence false alarms from the app.
About Smoke Detector Installation
Working smoke detectors cut the risk of dying in a home fire roughly in half, and the operative word is working. The detectors that fail are the ones past their 10-year sensor life, the battery units with dead batteries, and the standalone alarms that sound in the basement while everyone sleeps upstairs.
Hardwired interconnection is the fix for that last one: when any detector triggers, every detector sounds. We install complete code-compliant systems, every bedroom, outside each sleeping area, every level, with battery backup and, if you choose, smart units that reach your phone wherever you are.

Hardwired with battery backup is code for most homes and strictly better: interconnection means a basement fire wakes the upstairs bedrooms immediately. Battery-only is a fallback where wiring is impractical.
Every 10 years, the sensors degrade even if the test button works. If yours are yellowed or predate 2016, they're due. We date-label every unit we install.
For many homes yes: phone alerts when you're away, app hush for burnt toast, and self-testing. Nest Protect and similar also speak the hazard's location instead of just shrieking.
Yes, wireless-interconnect models link hardwired and battery units by radio, giving older homes whole-house alerting without opening ceilings.
