How to prevent frozen pipes in a Kanata home

Which pipes freeze first in a Kanata home

In our experience after thousands of Kanata service calls, the failures cluster in four spots: the kitchen sink supply lines when the kitchen is on a north or west exterior wall; basement bathroom rough-ins on exterior walls; garage hose bibs and any plumbing run through the garage ceiling; and any pipe in a crawlspace or unheated mechanical room.

Houses built in Bridlewood, Beaverbrook, and Glen Cairn during the 80s and 90s often have copper supply lines on exterior walls with marginal insulation — that's the typical Kanata frozen-pipe scenario.

The cheap, high-impact prevention steps

Foam pipe-wrap insulation from any hardware store is $4-6 per six-foot section. Wrap every exposed run in your basement, garage, and crawlspace. Pay extra attention to elbows and tees — that's where the wrap usually leaves gaps.

If you have a known cold spot, a UL-listed self-regulating heat cable is the next step. Don't use the cheap thermostat-style ones; the self-regulating type can't overheat and is safe to leave on all winter.

Behavioural prevention

On any night below -25°C, open the cabinet doors under kitchen and bathroom sinks that sit on exterior walls. Let the warmed room air circulate to the pipes inside. If you have a basement bathroom you rarely use, run water through it weekly — standing water in a trap is much more likely to freeze than recently-moved water.

If a pipe does freeze

Shut off the main water valve immediately — this prevents flooding if the pipe has already cracked. Open the faucet on the affected line. Apply gentle heat (hair dryer, heat gun on low, towels soaked in hot water) starting from the faucet end and working toward the frozen section.

Never use a torch, open flame, or unattended heat source. If you can't access the frozen section or you're not sure it's still intact, call us — frozen-pipe response is one of our most common winter calls.
