How do I know if my pipes have frozen?

Frozen pipes typically show clear warning signs: no water flow from faucets, unusual sounds in walls, or visible frost on exposed pipes. The sooner you identify frozen pipes, the better chance you have of preventing them from bursting.

Water flow issues are usually the first sign. Turn on faucets throughout your home - if only a trickle comes out or nothing at all, you likely have frozen pipes. Start with faucets on exterior walls or in unheated areas like basements, crawl spaces, or garages, as these freeze first. You might also hear unusual sounds like banging, gurgling, or whistling when you turn on taps.

Visual inspection can reveal frozen sections. Look for frost or ice on exposed pipes, especially in unheated areas. Pipes may appear swollen or bulged if ice has formed inside. Check areas where pipes run along exterior walls, in unheated basements, or anywhere pipes are exposed to cold air. In Ottawa's harsh winters, pipes in poorly insulated areas are particularly vulnerable.

Temperature patterns also provide clues. If your home has heat but certain areas feel unusually cold, pipes in those zones may be frozen. Kitchen and bathroom faucets on north-facing walls often freeze first during Ottawa's cold snaps.

Act quickly if you suspect frozen pipes. Shut off your main water supply to prevent flooding if pipes burst. Open faucets to relieve pressure and allow water to flow once thawing begins. Never use open flames or high heat - this can damage pipes or create safety hazards. If you can't locate the frozen section or if pipes have already burst, this requires immediate professional attention.
