How it works

1

Inventory and test

We locate every detector, press the test button and listen for a strong alarm tone before touching a single battery.

2

Replace batteries

We swap in fresh batteries, seal the cover and test again to confirm the unit is working.

3

Flag problem units

Any detector that doesn't respond or is past its service life gets flagged for replacement so nothing falls through the cracks.

We can help

Problems we fix

  • Detectors on vaulted ceilings that homeowners can't safely reach alone
  • Units more than 10 years old that no longer sense smoke reliably
  • Interconnected hard-wired detectors where one failing battery sets off the whole chain
  • Dusty or insect-blocked sensors that generate false alarms

Good to know

Smoke Detector Battery Replacement — FAQ

How often should smoke detector batteries be replaced?

Standard 9-volt batteries need yearly replacement. Sealed 10-year batteries come with the detector and are replaced with the unit. We can do a whole-home battery swap in one visit.

When should I replace the detector itself, not just the battery?

Smoke detectors should be replaced every 10 years — that's when the sensing chamber degrades regardless of battery life.

Can you reach detectors on vaulted ceilings?

Yes. We bring extension ladders for high ceilings so you don't need to balance on a chair to do routine safety maintenance.
