What to Do When Your Pipes Freeze: A Step-by-Step Guide
Frozen pipes are a homeowner’s nightmare, particularly during Canada’s frigid winters. When water in your pipes freezes, it can block water flow, cause expensive damage, and even lead to burst pipes. Knowing how to handle frozen pipes can save you from stress and costly repairs. Here’s a step-by-step guide to help you manage this common winter issue.
Understanding the Problem: Why Do Water Pipes Freeze?
When temperatures drop below freezing, water in your pipes can solidify. This often happens in uninsulated or exposed pipes in areas like basements, attics, or exterior walls. Water expands as it freezes, putting immense pressure on the pipes, which can lead to cracks or bursts.
How long does it take a pipe to freeze?
This depends on factors like the pipe’s location, insulation, and water flow. On average, pipes can freeze in as little as six hours if temperatures drop significantly and no precautions are in place.
What to Do If Pipes Are Frozen
If you turn on a faucet and nothing comes out or water flows only in a trickle, your pipes are likely frozen. Here’s what you should do immediately:
- Locate the Frozen Pipe
Start by identifying which section of the pipe is frozen. Check areas where pipes are most exposed to the cold, such as basements, crawl spaces, or outdoor plumbing.
- Shut Off the Water
Turn off the main water supply to prevent potential flooding if the pipe bursts while thawing.
- Inspect for Damage
Examine the pipe for visible cracks or leaks. If you notice any damage, it’s best to call a professional plumber before proceeding.
- How to Unfreeze a Water Line Safely
You can try to thaw the frozen pipe using one of the following methods:
Warm Towels: Wrap warm (not boiling) towels around the frozen section of the pipe.
Hair Dryer or Space Heater: Use a hair dryer or space heater to warm the pipe gradually. Keep the heat source at a safe distance and avoid overheating.
Heat Tape: Apply electric heat tape if you have it available. This provides consistent, safe heat to thaw the pipe.
Important: Never use open flames like a blowtorch to thaw pipes, as this poses a significant fire hazard.

How to Thaw a Frozen Water Line Inside the Wall
If the frozen pipe is hidden behind a wall, it can be trickier to resolve. Here are a few methods to try:
Increase Indoor Heat: Raise the thermostat in your home to warm the walls.
Infrared Heater: Aim an infrared heater at the affected wall to thaw the pipe indirectly.
Cut an Access Panel: In extreme cases, you may need to cut an access panel to reach the frozen pipe.
If these steps don’t resolve the issue, it’s time to call a plumber for professional assistance.
How to Avoid Frozen Pipes in the Future
Prevention is the best defense against frozen pipes. Here are some practical tips to keep your water lines safe during winter:
- Insulate Pipes – Wrap pipes in unheated areas with foam insulation or heat tape to keep them warm.
- Seal Cracks and Openings -Inspect your home for gaps or cracks near pipes, particularly around windows and doors. Use caulk or insulation to seal them.
- Keep Water Moving – Let a small trickle of water flow through vulnerable pipes during extremely cold weather. This prevents freezing by maintaining water movement.
- Maintain Indoor Heat – Keep your home heated to at least 10°C (50°F), even if you’re away, to prevent interior pipes from freezing.
- Disconnect Outdoor Hoses – Remove garden hoses and shut off outdoor faucets to prevent freezing in exterior pipes.
What If the Worst Happens?
If your frozen pipe bursts, shut off your home’s main water supply immediately to minimize water damage. Then, contact a plumbing company for emergency repairs. Acting quickly can save your home from extensive water damage and costly repairs.
How to Thaw a Frozen Water Line: DIY vs. Professional Help
While DIY methods can be effective for minor freezing issues, knowing your limits is important. If you’re unsure of the pipe’s condition or can’t safely access it, hiring a professional plumber is the best option. A trained expert can identify the problem, safely thaw the pipe, and make necessary repairs to prevent future issues.
When to Call a Plumber
There are situations where professional help is essential:
- The pipe is inaccessible or located behind walls.
- You notice cracks, leaks, or water damage.
- DIY thawing methods don’t work after several hours.
- A frozen pipe has burst, causing flooding or severe damage.
A qualified plumbing company can resolve the issue quickly and effectively, saving you time and stress.
