When it's time to call

  • Chirping that won't stop

    A new battery didn't fix it? Hardwired alarms also chirp when they reach end of life or have a wiring fault.

  • Alarms more than 10 years old

    Check the date on the back. Smoke alarm sensors wear out, and manufacturers call for replacement at 10 years.

  • Alarms that don't sound together

    Battery-only or non-interconnected alarms mean a fire in the garage may not wake anyone in the bedrooms.

  • Selling, renting or remodeling

    Inspections and remodel permits often require alarms in every bedroom, outside sleeping areas and on each level.

Every alarm talking to every other

I replace expired alarms with new hardwired units that have battery backup, matched or adapted to your existing wiring so every alarm in the house sounds together.

Where there's no wiring to a bedroom or hallway, I can usually fish new cable through the attic, or use hardwired alarms with wireless interconnect so nothing needs to be opened up. Combination smoke and carbon monoxide alarms go where gas appliances or an attached garage call for them.

Smoke Detector Wiring & Replacement FAQs

How often should smoke detectors be replaced?

Every 10 years from the manufacture date printed on the back, or sooner if one fails its test. Replacing them all at once keeps the interconnection matched.

Why does my smoke detector keep chirping?

Usually a low backup battery, but hardwired alarms also chirp at end of life or when there's a wiring problem. If a new battery doesn't stop it, the alarm likely needs replacing.

Can you add hardwired alarms to an older home without tearing up walls?

Usually, yes. I fish cable through the attic where possible, or use hardwired alarms with wireless interconnect so every alarm still sounds together.

Do you install carbon monoxide detectors?

Yes. Combination smoke and CO alarms are recommended in homes with gas appliances, a fireplace or an attached garage.
