Key Takeaways
- Frozen pipes can cause thousands of dollars in damage, but taking preventive steps is simple and affordable.
- Insulating pipes in basements, crawl spaces, attics, garages and along exterior walls helps protect them from freezing temperatures.
- Disconnecting and draining outdoor hoses and faucets before the first freeze prevents ice from forming and damaging your plumbing.
- Keeping your thermostat set to at least 13°C (55°F), even when you’re away, reduces the risk of indoor pipes freezing.
Why Preventing Pipes from Freezing is Essential
When temperatures plunge, one of the biggest threats to your home is frozen pipes. What starts as ice inside a pipe can quickly turn into a major disaster — blocking your water supply, cracking pipes and releasing gallons of water that can cause extensive damage once the ice melts. Even durable copper or PVC pipes can fail under the pressure of expanding ice, leading to costly repairs, cleanup and major disruption to your daily life.
Pipes located in unheated areas such as garages, crawl spaces, basements and exterior walls are especially vulnerable. The good news? Preventing frozen pipes is both straightforward and affordable. By taking a few proactive steps now, you can protect your plumbing, avoid unnecessary stress and enjoy peace of mind throughout the winter. Below are practical, actionable solutions every homeowner should know.
How to Prevent Freezing Pipes
Insulate pipes in vulnerable areas
One of the most effective ways to prevent frozen pipes is proper insulation. Foam pipe sleeves, fibreglass wraps or heated cables designed for the job add an extra layer of protection against icy temperatures. Start with pipes in unheated areas: basements, crawl spaces, attics and garages. Don’t overlook pipes that run along exterior walls, even if they’re inside cabinets. Pipe insulation is inexpensive, easy to install and often available at any hardware store. For homes in extremely cold climates, consider adding electric heat tape for extra security.
Disconnect and drain outdoor faucets
Outdoor plumbing is often the first to freeze. Before winter sets in, disconnect garden hoses, drain them fully and store them indoors. Next, shut off the water supply to outdoor faucets from inside the house, then leave the faucet open to let any remaining water escape. If water remains trapped, it can freeze, expand and push back into your indoor pipes—leading to cracks, bursts and costly damage. Taking a few minutes to drain your outdoor faucets now will keep your system safe all season long.

Maintain a safe indoor temperature
Pipes inside your home rely on consistent warmth to prevent freezing.
- Always keep your thermostat set to at least 13°C (55°F), even if you’re not home.
- Cold snaps often hit overnight, so avoid lowering the heat too much at bedtime.
- Open cabinet doors under sinks in the kitchen or bathroom to allow warm air to circulate around pipes.
- A steady indoor temperature is one of the easiest and most reliable ways to prevent frozen pipes.
Seal drafts and improve insulation
Drafts are one of the hidden causes of frozen pipes. Cold air sneaking in through gaps around doors, windows or points where the pipes enter the home can quickly drop the temperature enough to freeze nearby plumbing. Use caulk, spray foam or weatherstripping to seal these leaks. Adding insulation in basements, crawl spaces or attics not only keeps pipes warmer but also improves your home’s energy efficiency.
When to Call a Plumber
Some homes are more vulnerable to frozen pipes than others. If you live in an older home, have pipes that seem to freeze every winter or suspect that one of your pipes may already be frozen, don’t wait—call a licensed plumber. They have the right tools to thaw pipes without causing additional damage. Calling a plumber early can reduce the risk of a major water major emergency.
Protect Your Plumbing This Winter
Preventing frozen pipes isn’t complicated—it just requires a little preparation. By insulating pipes, draining outdoor faucets, maintaining a safe indoor temperature and sealing drafts, you can reduce the risk of frozen or burst pipes. Taking these steps now will help you avoid expensive repairs and give you peace of mind all winter long. A little prevention today means a safer, warmer home tomorrow.
