Frozen Pipes in Saskatoon: Deep Frost, Frozen Services and Thawing Without a Disaster

Where is the freeze?

Open a tap on each floor. If nothing runs anywhere, including the basement, the freeze is likely in the water service between the street and the house or where it enters the foundation. If some taps run and one does not, the freeze is inside, usually on an exterior wall, in a crawlspace, or behind a kitchen cabinet on a north wall. Feel along the exposed pipe for the coldest section and look for frost.

Saskatoon’s older neighbourhoods have shallower and older services and freeze first. If neighbours have lost water too, the frost has reached the main and the City is the first call.

What the City does and what is yours

The City of Saskatoon tracks frost depth through the winter and, in hard winters, has advised at-risk properties to run a small stream of cold water continuously, with adjustments to the water bill. If a service freezes, the City is responsible for the section it owns, from the main to the property line, and can be reached through its customer service line; the section from the property line into the house is the owner’s. Ask the City to confirm its side is clear before paying a plumber to look, and keep any run-water notice for the bill adjustment.

Water and sewer services in Saskatoon are the City’s utility; SaskWater serves communities outside the city. Rural properties on wells are entirely the owner’s responsibility from the well to the tap.

Thawing without a fire or a burst

Plumbers thaw metal water services with electric thawing machines that pass a low-voltage current through the pipe, and plastic services with warm water pumped through a small line fed into the frozen section. Both need experience: the wrong current on the wrong pipe has started house fires, and heating a frozen pipe from the wrong end traps expanding water and bursts it. Never use a torch. Inside the house, a hair dryer or heat lamp on the coldest exposed section, with the tap open so meltwater can escape, is safe; a space heater in a crawlspace is not something to leave unattended.

Open the tap before you start and leave it open. Once water flows, check every joint along the thawed section for drips; a pipe that froze once often has a split that only shows under pressure.

• Tap open at the frozen fixture before thawing
• Water shutoff location known and working
• No open flame, ever
• Plumber’s thawing method matched to the pipe material
• Joints checked for leaks after flow returns

Insurance and prevention

Burst-pipe damage is usually covered by a Saskatchewan home policy, but frozen-pipe claims can be denied if the house was left unheated or unchecked beyond the policy’s limit without the water shut off. If you travel in winter, shut the main and drain the system or have someone check the house. Photograph damage before cleanup.

Prevention is cheaper than thawing: insulate the pipe where it enters the foundation, seal drafts around the sill plate, keep cabinet doors open on north walls in a cold snap, and heat-trace pipes in crawlspaces with a listed heating cable on its own protected circuit, installed under a SaskPower electrical permit if a new circuit is needed. Snow on the ground insulates the service; do not clear the lawn over it.
