- Smoke & CO Alarms
Smoke Detector and Carbon Monoxide Alarm Wiring for Worcester County Homes
Massachusetts law requires hardwired, interconnected smoke and carbon monoxide alarms in most homes, and every home sale needs a fire department certificate of compliance. Bergeron Contracting installs, replaces, and interconnects hardwired smoke and CO alarms across Worcester County so your home is safe, up to code, and ready to pass inspection.
Will your home pass its smoke and CO alarm inspection?
Whether you are selling, remodeling, or just overdue for an update, hardwired smoke and CO alarms have to be placed, powered, and interconnected exactly the way Massachusetts requires. We handle it from start to finish.
Quality you can count on
Every smoke and CO alarm we install is wired to current Massachusetts code and NFPA 72, interconnected, and tested before we call it done. You get a system that is ready for inspection and clear communication at every step.
A team built on one standard
Paul Bergeron Jr. founded this company in 2006 on the belief that electrical work should be done right the first time. Every alarm job we take on is held to that same standard, from placement to the final interconnection test.

Types of smoke and CO alarm work we handle
Smoke and CO Alarm Wiring Explained
Hardwired, Interconnected Alarms
In homes built or renovated after 1975, Massachusetts requires smoke alarms to be hardwired, interconnected, and backed up by battery so they all sound together and keep working during a power outage. We run the wiring, interconnect the units, and confirm the whole system trips as one.
Carbon Monoxide Alarms
Homes built after September 2008 require hardwired, interconnected carbon monoxide alarms on every habitable level and within ten feet of every bedroom. We install CO and combination smoke and CO alarms in the right locations to meet code.
Replacements and Upgrades
Smoke and CO alarms expire, usually after ten years. We replace outdated or failed detectors, swap in current photoelectric units, and upgrade older battery-only setups to hardwired where the home requires it.
Testing and Interconnection
We test every alarm and confirm the interconnection so that when one sounds, they all do. That is exactly what the fire department checks at inspection.
Wired to Massachusetts Code, Ready for Inspection
We install smoke and CO alarms in accordance with the Massachusetts smoke and carbon monoxide alarm regulations, the state building code, and NFPA 72, including the placement, power source, and interconnection rules for your home’s construction date. Getting these details right is the difference between passing and failing inspection.
Bergeron Contracting handles the wiring so your home is ready for the local fire department walkthrough. If you are selling, we help you reach a certificate of compliance without surprises on inspection day.
Home Sales, Remodels, and New Construction
Whether you are selling a home that needs to pass a smoke and CO inspection, updating detectors during a remodel, or wiring alarms for a new build, Bergeron Contracting completes the electrical work safely and to code.
We add and interconnect detectors during remodels and additions, replace expired units, and wire complete smoke and CO alarm coverage for new construction. If your detectors are chirping, sounding for no reason, or not interconnected, we track down the cause and correct it.

Frequently Asked Questions
In homes built or renovated after 1975, yes. Massachusetts requires smoke alarms to be hardwired, interconnected, and equipped with battery backup. Homes built before 1975 can use battery, hardwired, or a combination. We confirm what your home construction date requires and wire it to match.
Yes. Before a sale, the local fire department inspects the home and issues a certificate of compliance for smoke and carbon monoxide alarms. It is valid for sixty days. If your alarms do not meet code, we install or update them so you can pass and get your certificate.
In homes built after September 2008, hardwired interconnected CO alarms are required on every habitable level and within ten feet of every bedroom. Older homes still need CO alarms, and we place them to meet the current standard for your home.
Yes. Chirping usually means a low backup battery or an alarm past its ten-year life, and false alarms often come from an aging or misplaced detector. We diagnose the cause, replace what needs replacing, and confirm the interconnection so the system behaves.
Most smoke and CO alarms are rated for about ten years from their manufacture date, then they need to be replaced even if they still power on. We check the dates on your units and replace any that are expired or close to it.
In many homes, yes. If the wiring allows, we interconnect your hardwired detectors so that when one sounds, they all sound. Where wiring is not present, we run it or use listed wireless-interconnect alarms to meet the requirement.
Yes. Combination smoke and CO units are a common way to meet both requirements in the right locations. We install combination and dedicated alarms to match your home layout and code requirements.
