Why Smoke & Carbon Monoxide Detectors Matter for Ottawa Homeowners

Why Smoke & Carbon Monoxide Detectors Matter for Ottawa Homeowners
When it comes to home safety, few devices are as important—or as often overlooked—as smoke and carbon monoxide (CO) detectors. These small, inexpensive devices provide early warning when seconds matter most, yet during home inspections they are frequently outdated, improperly located, or no longer functioning.
At Atlas Peak Inspections, a professional home inspection company serving Ottawa and the surrounding areas, detector-related issues are among the most common safety findings we encounter. The good news is that they are also one of the easiest issues for homeowners to correct.
Why Smoke and Carbon Monoxide Detectors Are Critical
Smoke detectors alert occupants to fire early, often before flames are visible. Carbon monoxide detectors warn of a colourless, odourless gas that cannot be detected by human senses. Both hazards can escalate quickly, leaving little time to react without a working alarm.
Properly installed and maintained detectors can:
Provide early warning to escape safely
Reduce the risk of serious injury or loss of life
Offer peace of mind for homeowners and families
How Many Detectors Should a Home Have?
A common question we hear during inspections is, “How many detectors do I actually need?”
As a general best practice, every home should have:
At least one smoke detector on every level of the home
Smoke detectors outside sleeping areas
Carbon monoxide detectors on every level of the home, especially near bedrooms
Local building codes and manufacturer recommendations may vary, but this approach provides a strong baseline for safety.
Understanding Detector Age and Discolouration
Many homeowners are surprised to learn that smoke and carbon monoxide detectors do not last forever. Most units have a recommended service life of 7 to 10 years.
Discolouration—often yellowing or browning of the plastic—is a common sign of aging. This is not caused by paint, but by the breakdown of fire-retardant materials in the plastic due to heat, UV exposure, and airborne contaminants over time. When a detector shows visible aging, it is often near or past the end of its effective lifespan and should be replaced.
Checking the manufacture or expiry date on the back of the unit is one of the simplest safety checks a homeowner can perform.
Battery Maintenance Still Matters
Even newer detectors require regular attention. Batteries should be replaced at least once a year, or immediately if the unit chirps or signals low power. Many homeowners choose a consistent annual reminder—such as the start of the new year—to handle battery replacement and testing.
Detectors should also be tested regularly to confirm they are functioning properly.
A Common Inspection Finding
During home inspections, it is common to find:
Missing detectors on certain floors
Expired or discoloured units
Disabled or non-functioning alarms
Detectors that have been painted over or obstructed
These issues are usually easy to correct, but if left unaddressed, they can significantly increase risk.
