Professional Smoke & CO Detector Installation Services

Smoke detectors and carbon monoxide (CO) alarms are your home's first line of defense against two of the most dangerous household threats. According to the NFPA, three out of five home fire deaths occur in homes with no smoke alarms or with non-working smoke alarms. CO is an odorless, colorless gas produced by gas furnaces, water heaters, stoves, and fireplaces that can be lethal at high concentrations.

Hardwired smoke and CO detectors are interconnected — when one alarm activates, all alarms in the home sound simultaneously, ensuring everyone is alerted regardless of where the fire or CO source is located. Battery-only alarms do not provide this interconnection and are not permitted in new construction under most building codes.

Current building codes require smoke detectors in every bedroom, outside each sleeping area, and on every level of the home (including the basement). CO detectors are required outside each sleeping area and on every level in homes with gas appliances, attached garages, or fireplaces. Many jurisdictions now require combination smoke/CO detectors to simplify compliance.

Licensed electricians install hardwired, interconnected smoke and CO detectors throughout the home. For existing homes being brought up to code (often required during home sales or renovations), the electrician runs wiring between detector locations and connects them to a dedicated circuit. For homes with existing hardwired detectors, replacement with modern units (which have sealed 10-year lithium batteries as backup) ensures reliable operation even during power outages.
