What this job involves
An iced-up pipe is a rupture in waiting. The ice first stops the flow; then pressure trapped between the plug and the shut faucet beyond it splits the copper. If a tap coughs out nothing, or a trickle, on a brutal January morning, a stretch upstream has frozen. Thawing it from the faucet end back toward the ice gives meltwater and pressure an exit as it clears.
How the job goes
- Open the dead faucet so meltwater and pressure have a way out.
- Follow the line to its coldest stretch, usually an outside wall or crawlspace.
- Warm it gently with a heat gun or pad, never a torch.
- Once water flows, look the thawed length over for splits.
- Recommend insulation, heat cable or a reroute for that section.
Warning signs on your pipes
- One faucet is dry on a frigid morning.
- Frost on an exposed length of pipe.
- A bulge or hairline crack in the pipe surface.
- Odd smells from drains as traps freeze.
- A kitchen tap on an outside wall slows to a dribble.
From the job notes
Bungalows and split-levels from the sixties and seventies all over Oakville often place the kitchen sink on an outside wall, and the supply lines in those walls are vulnerable.
Bungalows and split-levels from the sixties and seventies all over Oakville often place the kitchen sink on an outside wall, and the supply lines in those walls are vulnerable. Propping the cupboard doors open on frigid nights lets room heat reach them and helps enormously.
Garages and crawlspaces are the other trouble spots. A pipe crossing an unheated garage toward an outside tap, or a bathroom above, can freeze even while the rest of the house is cosy.

Questions we hear
Is a hair dryer safe to use?
Yes, with care, beginning at the faucet end. A torch flame inside a wall cavity is how houses catch fire.
Does every frozen pipe split?
Many survive, yet the gamble is poor. Thaw it soon and inspect it once water moves.
