Smoke & CO detectors
Hardwired smoke and carbon monoxide detectors, installed or replaced by Martinez Electric LLC. We’re based in Derry, NH and take jobs in New Hampshire, Massachusetts and Maine.
What’s included
Hardwired detectors run on your home’s power with a battery backup, and they can be linked so that when one sounds, they all do. Detectors also wear out: most makers say to replace smoke detectors about every 10 years.

Worth knowing
Look for the date on the back of each detector. If it’s about 10 years old, or you can’t find a date, it’s time to replace it.
