How do plumbers actually thaw a pipe?

Pipe thawing machines run a low-voltage current through the pipe to warm it from the inside out, which is much faster and safer than external heat. Verified Edmonton plumbers on OnCall Pros carry these on the truck during winter.

If my pipe hasn't burst yet, is it really an emergency?

Yes. A frozen pipe is a soon-to-be-burst pipe — the longer it sits frozen, the higher the chance the ice expansion splits it. Prevention is dramatically cheaper than burst-pipe repair plus water damage.

What does winter prevention cost?

Booking a plumber to insulate vulnerable lines and add heat tape in the fall is a fraction of the cost of one burst-pipe call. Good off-season investment for older Edmonton homes.

What if it's the water main from the street?

If your service line itself is frozen — no water anywhere, even after a long thaw — that's an EPCOR call, not a plumber call. We'll tell you in the intake which it likely is.

What we cover

No water at one tap

Other taps work normally — the freeze is on a single branch line, usually in an exterior wall or unheated space.

No water anywhere

Whole-house freeze, often the main line in a crawl space or near the foundation. Higher burst risk.

Visible frost on a pipe

If you can see the frozen section, the plumber can thaw it before it splits.

Bulging or cracked pipe

Already burst (or about to). Treat this as a burst-pipe emergency — shut off the water now.

What to do before the plumber arrives

1
Open the affected tap to a drip.
Gives expanding ice somewhere to push and reduces the chance of a burst while you wait.
2
Locate your main shut-off — but don't close it yet.
If the pipe does burst before the plumber arrives, you want to be able to shut the water off in seconds.
3
Warm the area gently — no open flame.
A hairdryer, heat lamp, or space heater pointed at the suspected freeze location. Never a propane torch — that's the leading cause of house fires from DIY thaws.
4
Open cabinet doors under sinks on exterior walls.
Lets household heat reach the supply lines — especially important on north-facing kitchen and bathroom sinks.
5
Don't pour boiling water on a frozen pipe.
Thermal shock can crack copper. Slow, even warming is what works.

Edmonton-specific notes

Edmonton's deep winter (sustained −25 °C with windchill) regularly freezes any pipe in an exterior wall, attached garage, or vented crawl space. Older Mill Woods, Capilano, and Beverly homes with non-insulated kitchen plumbing on north walls are the most common service calls here. The single highest-risk night of the year in Edmonton is the first overnight low below −20 °C after a chinook — homes that were warm for a week suddenly drop to ambient on the worst-insulated runs and freeze within hours. If a chinook is on the way out and the forecast turns cold, leave a pencil-thick stream running on the most exposed cold tap overnight; the moving water buys you the temperature margin you need.
