Smoke & Carbon Monoxide Detectors: What to Look For & When to Replace
Smoke alarm maintenance & installation should be taken very seriously. Here's what you can do to protect your home today!

How to tell if your detection systems need to be replaced:
1. Pay close attention to the colour & physical condition of the alarm:
If you noticed that it has a yellow hue or is showing visible/physical signs of aging or deterioration, then it needs be replaced.
2. Even if the unit appears to be in good physical condition:
You should always make sure that the unit has fresh batteries.
Most alarms will begin to "chirp" when the batteries are running low. As a general rule of thumb, you should replace them with fresh batteries at least once per year.
After installing the new batteries, be sure to hit the test button located on the unit to make sure it is in working order.
Additionally, you can also purchase an aerosol smoke detector test spray to further inspect your unit. These test canisters/sprays are widely available at most hardware stores.
3. Even with fresh batteries:
If your detection system appears to malfunction or sound at random times on a frequent or infrequent basis. We recommend that you replace it.
4. Smoke & Carbon Monoxide Detectors should be replaced every 10 years or sooner (regardless of appearance or functionality).
If you're unsure how old your detection units are or when they were installed, then we recommend you have them replaced.
When it comes to the safety of your home and family, this is an area of home maintenance that should be a top priority. And for your peace of mind, it's better to be safe and confident knowing that these systems are in working order.
