As Canadian winters roll in, the freezing temperatures don’t just affect the outdoors, they can wreak havoc on your home’s plumbing. Frozen pipes, hidden leaks, and unnoticed wear and tear can lead to costly repairs, water damage, and major inconvenience right in the middle of winter.
That’s why every homeowner should follow what we call The Freeze Protocol; a simple set of winter plumbing checks that keep your home safe, warm, and protected before the first deep freeze hits.
Here are the 3 plumbing checks every Canadian home needs before November:
1. Inspect and Protect Outdoor Faucets
Outdoor taps (also called hose bibs) are the first to freeze in cold weather. If water is left inside, the pipe can expand and burst once temperatures plummet.
What to do:
- Shut off the water supply to all outdoor faucets.
- Disconnect garden hoses and drain them fully.
- Install insulated faucet covers for extra protection.
Pro tip: If your home doesn’t already have frost-free outdoor faucets, consider upgrading before winter. It’s a small investment that prevents big headaches.
2. Check for Leaks and Weak Spots
Even the smallest leak can turn into a disaster when freezing temperatures expand water inside the pipes.
What to do:
- Look under sinks, behind toilets, and in the basement for damp spots.
- Check visible pipes for rust, cracks, or signs of moisture.
- Have a licensed plumber test the water pressure to catch hidden leaks.
Pro tip: If you notice unusually high water bills, you may already have a hidden leak. Catching it now could save you thousands in water damage.
3. Insulate Exposed Pipes
Pipes in unheated areas like garages, crawl spaces, or basements are the most vulnerable to freezing. Proper insulation keeps them warm and reduces the risk of burst pipes.
What to do:
- Use foam pipe sleeves or heat tape to wrap exposed pipes.
- Seal gaps around walls and floors where cold air can seep in.
- If your home has a history of frozen pipes, consider installing smart leak detectors for added peace of mind.
Pro tip: Don’t forget about the pipes near exterior walls, especially behind kitchen and bathroom cabinets, these areas can get colder than you think.
