Thawed Safely Before the Pipe Bursts

It depends on location and accessibility. If you can see and reach the frozen section — under a sink, along a basement wall — gentle warmth from a hair dryer on low setting can work. Keep the dryer moving and open the connected faucet. For pipes inside walls, under floors, or in crawl spaces, you need professional thaw equipment. You cannot safely heat what you cannot see, and hidden freezes are often more extensive than they appear from outside.

Sometimes it is obvious — water pouring from a wall or ceiling. More often, a burst pipe stays hidden until the ice plug melts and water starts flowing through the crack. Warning signs: water stains on walls with no source, the sound of running water when everything is off, a sudden drop in water pressure, or damp and bulging drywall. If you suspect a burst, shut off your main water supply and call immediately.

Emergency thawing runs $300 to $600 depending on pipe location and how accessible the frozen section is. Burst pipe repair varies with the extent of damage. Upfront pricing is provided after assessment — you approve the number before any work starts. For context: winterization to prevent this next year runs $200 to $500 for most homes.

Not if the root cause is addressed. Pipes freeze for specific, identifiable reasons: poor insulation, cold air gaps, inadequate heating in certain areas. After resolving the freeze, the technician shows you exactly where and why it happened and gives you a prevention plan. Fixing those underlying issues eliminates repeat events in the same location.

At -6C (20F) or below, especially during sustained cold. Wind chill amplifies the risk for pipes in exterior walls. Duration matters as much as temperature — three consecutive days at -10C is more dangerous than one night at -20C. Keep indoor temperatures at 13C (55F) minimum, even in unused rooms or while traveling. If a deep freeze is forecast, open cabinet doors under sinks and let faucets drip.
