Why Placement Matters as Much as the Detector
A detector in the wrong spot can miss a fire or nuisance-trip until someone disconnects it. Proper coverage is about the right units in the right places. Here's what's involved: ONTARIO REQUIRES (and we follow): - A smoke alarm on every storey of the home - A smoke alarm outside all sleeping areas - A CO alarm near sleeping areas if you have fuel-burning appliances or an attached garage A PROPER INSTALL: - Right unit for the location (smoke, CO, or combo) - Correct placement (not too close to kitchens/baths to avoid nuisance trips) - Hardwired units interconnected where applicable - Every unit tested before we leave DETECTORS EXPIRE: - Replace smoke alarms every ~10 years, CO every 7–10 - Check the date on yours—old ones may not trigger reliably The right alarms in the right places is the cheapest life-safety upgrade there is.
We Install Detectors Across Barrie
Bedrooms, hallways, every storey, and near fuel-burning appliances and garages. Smoke, CO, and combo units across every Barrie neighbourhood from Holly to South Shore to East Bayfield to Allandale.
EXPIRED DETECTOR REPLACEMENT
The most common job. Detectors are 7–10 years old and past their reliable life. We swap them for fresh units ($125 each)—hardwired or battery—placed right and tested.
HARDWIRED & INTERCONNECTED
Replacing hardwired, interconnected detectors so when one sounds, they all do. We match the right interconnected unit and confirm the whole chain works together after install.
CARBON MONOXIDE ALARMS
CO is odourless and deadly. If you have fuel-burning appliances or an attached garage, Ontario requires a CO alarm near sleeping areas. We install CO and combo smoke/CO units, placed correctly.

Smoke & CO Detector Frequently Asked Questions
Here are some common questions we get from our customers.
$125 per detector—whether it’s a hardwired smoke alarm, a battery unit, a CO detector, or a combo smoke/CO. Bundling several into one visit is the efficient way to bring a whole home up to code. You supply the units (we’ll advise); plus 13% HST.
Ontario law requires a working smoke alarm on every storey and outside all sleeping areas, plus a CO alarm near sleeping areas if you have fuel-burning appliances or an attached garage. We’ll assess your home and install the right mix to make it compliant.
Often, yes. Chirping usually means a low battery, but if the unit is 7–10 years old it’s past its reliable life and should be replaced entirely. We’ll check the date and swap it for a fresh, working unit.
Smoke alarms roughly every 10 years and CO alarms every 7–10—they have a printed expiry date. Old detectors may not trigger reliably in a real emergency, which is exactly when you need them, so replacing on schedule matters.
Yes. We match the right interconnected units so when one alarm sounds, they all do, and we confirm the whole chain works together after install. It’s $125 per unit, tested.
Near sleeping areas, so they wake you, and Ontario requires them if you have fuel-burning appliances (furnace, gas range, fireplace) or an attached garage. We place them correctly—not too close to the appliances themselves, which causes nuisance trips.
Yes, and it’s the smart approach. We assess every storey and sleeping area, install the right mix of smoke and CO units, interconnect where needed, and test everything—getting you fully covered and compliant at once.
Yes. WSIB clearance and liability coverage, with code-correct placement and a working test on every unit. All detector work is backed by our satisfaction guarantee.
