Frozen Pipe Repair

Home › Plumbing Services › Frozen Pipe Repair

Ontario winters are hard on plumbing. When a pipe freezes, the ice expands and builds pressure until the pipe can split, often flooding the area once it thaws. Plumber On Demand thaws frozen pipes safely and repairs any damage before it becomes a burst pipe emergency.

Signs you have a frozen pipe

• No water or a trickle from one or more taps on a cold day
• Frost on exposed pipe in basements, crawl spaces or garages
• Strange smells from drains when water cannot move through the line
• Bulging or cracked pipe which means it may already be damaged

What to do right away

Shut off the main water valve if you suspect a frozen pipe, so you are ready if it has split. Open the affected tap so melting water has somewhere to go. You can gently warm the area with a space heater or hair dryer kept at a safe distance, but never use an open flame. If you cannot find the frozen section or it is inside a wall, call us.

How we thaw and repair

We locate the frozen section, thaw it safely with the right equipment, and check the pipe for cracks or split fittings under pressure. Damaged pipe is replaced before the water is turned back on. If the line has already burst, see our leak repair page and call immediately.

Preventing frozen pipes

Pipes on exterior walls, in unheated spaces and near garage doors freeze most often. Insulating them, sealing drafts, shutting off and draining outdoor hose bibs, and keeping the heat on when you are away all help. We can also reroute or insulate lines that freeze every winter.
