In Canada, freezing temperatures aren’t just uncomfortable — they’re a serious threat to your property. One of the most common (and expensive) issues homeowners face during the winter is a burst pipe. When water freezes inside a pipe, it expands. This pressure can cause the pipe to rupture, leading to sudden flooding and water damage that spreads quickly through floors, walls, and insulation.

But the good news is, most of these emergencies are preventable.

Why Pipes Freeze — and Where It Happens

The pipes most likely to freeze are often the ones you don’t think about: those running through unheated spaces like basements, crawlspaces, garages, and along exterior walls. Even pipes under kitchen or bathroom sinks can be at risk, especially if cabinet doors stay closed and trap the cold in.

When temperatures drop below zero, these areas are vulnerable — especially during prolonged cold snaps or overnight freezes.

How to Keep Your Pipes Safe

Keeping your home warm is the first line of defence. Even if you're heading out of town, your thermostat should never be set below 13°C (55°F). Turning off your heat entirely during a winter getaway might save a few dollars — but it can cost you thousands in repairs if a pipe bursts while you’re gone.

It’s also smart to let warm air circulate inside your home. Opening cabinet doors below sinks during extreme cold can help, and sealing any drafts or cracks near pipes is a simple way to prevent trouble.

For outdoor faucets, the risk is just as real. If you haven't already, disconnect garden hoses, shut off the valve inside, and drain any water left in the line. Installing frost-proof hose bibs is an extra safeguard worth considering.

More Than Pipes: Other Winter Water Threats

Frozen pipes aren’t the only way water damage happens in winter. Melting snow can seep into foundations, and sump pumps can fail just when you need them most. That’s why having a working sump pump — ideally with a battery backup — is key. Water sensors and smart shut-off valves can also alert you to leaks early, helping you take action before things get worse.

What to Do If a Pipe Bursts

If the worst happens and a pipe does rupture, act fast. Shut off your home’s main water supply immediately. If water is near any electrical outlets or systems, turn off the power at the breaker — only if it’s safe to do so.

Don’t try to thaw frozen pipes with an open flame or torch. This is not only dangerous, it could also cause more damage. Instead, call a professional right away.
