A Recent Gainesboro Install

"A family in a three-bedroom home contacted us after their home inspection flagged their detectors — eight units, all hardwired, all installed in 2009. We replaced all eight, upgraded two to combo smoke/CO units, confirmed interconnects, and documented everything. Total time: under three hours."

Frequently Asked Questions

How often should smoke detectors be replaced?

Every 10 years, regardless of how they look or sound. The chemical sensors degrade even when the unit is silent.

What's the difference between ionization and photoelectric?

Ionization detects fast flaming fires. Photoelectric detects smoldering fires. Most current recommendations favor photoelectric or dual-sensor units.

Do I need carbon monoxide detection if I don't have gas?

Yes if you have an attached garage. CO from idling cars can migrate into the home.

Can I install smoke detectors myself?

Battery-only units yes. Hardwired units that connect to your home's electrical system require a licensed electrician for code compliance.

What does proper interconnection mean?

When one detector senses smoke, all detectors in the home alarm simultaneously — giving you critical extra time to react.
