When temperatures drop below -30°C in North Bay — and they do every winter — frozen pipes are not a question of if, but when. We provide emergency pipe thawing, frozen pipe repair, and winterization to protect your home from one of Northern Ontario's most common plumbing disasters.
North Bay Plumbers provides 24/7 frozen pipe repair and emergency thawing services across North Bay, Callander, and Sturgeon Falls. North Bay's winters regularly reach -30°C to -40°C, making frozen pipes one of the most common plumbing emergencies in the Nipissing District. We respond within 60 minutes to thaw frozen pipes before they burst, repair pipes that have already split, and provide winterization services to prevent freeze-ups. Call 705-482-1253 immediately if your pipes have stopped flowing in winter — time is critical.
Frozen pipes don't always announce themselves with a dramatic burst. Watch for these warning signs — catching a freeze early can save you thousands in water damage.
Frozen pipes can burst within hours. Here's exactly how we handle every frozen pipe call — fast, safe, and thorough.
We dispatch immediately. Frozen pipes can burst within hours. Our trucks carry professional thawing equipment including heat guns, pipe heating cables, and infrared heaters — everything needed to safely restore flow on the first visit.
We trace the plumbing system to find exactly where the ice blockage is. Common locations: exterior walls, unheated crawl spaces, garage supply lines, and pipe runs near poorly insulated rim joists. Pinpointing the freeze saves time and prevents unnecessary wall opening.
We apply heat gradually and evenly to avoid thermal shock that can crack pipes. Never use open flame — that's a fire hazard and can damage pipes. Professional thawing equipment provides controlled, safe heat application that restores flow without creating new problems.
As the pipe thaws, we inspect for cracks, splits, or joint failures caused by ice expansion. Water expands 9% when it freezes — enough pressure to split copper, PEX, and even steel pipes. We repair any damage found before restoring full water pressure.
We identify WHY the pipe froze and fix the root cause. This may include adding pipe insulation, heat cable installation, sealing air leaks, or rerouting vulnerable pipe sections. We prevent the same pipe from freezing again — not just fix today's problem.
North Bay's extreme winters create frozen pipe conditions that most of Southern Ontario never experiences. Here's what makes our region different — and why local expertise matters.
Environment Canada data shows North Bay averages 35+ days below -20°C each winter, with cold snaps regularly hitting -30°C to -40°C with wind chill. The frost line in the North Bay area extends 4-5 feet deep — deeper than many Southern Ontario cities. Pipes buried less than 5 feet are at risk.
Homes built in the 1950s-70s in West Ferris, downtown, and the south end often have plumbing runs through exterior walls or unheated crawl spaces — building practices that didn't account for the insulation standards we know today. These homes are our most frequent frozen pipe calls.
Trout Lake, Lake Nipissing waterfront, and Callander properties that sit vacant in winter are extremely vulnerable. Improper winterization is the #1 cause of catastrophic burst pipe damage in seasonal homes. We provide full winterization and spring startup services.
A frozen pipe doesn't always burst at the ice blockage — pressure builds between the ice and the closed faucet, and the pipe can split anywhere along that section. By the time the ice thaws naturally in spring, water floods through the split. Getting pipes thawed professionally before they burst saves thousands in water damage.
Frozen pipe repair costs depend on the number of pipes affected, accessibility, and whether the pipe has already burst. Here's what to expect.
First, turn off the main water supply to prevent flooding when the pipe thaws. Open the affected faucets to relieve pressure. Do NOT use a blowtorch or open flame. Call 705-482-1253 immediately — frozen pipes can burst within hours, and professional thawing is the safest approach.
If you turn on a faucet and get no water or just a trickle during sub-zero weather, frozen pipes are the most likely cause. If multiple fixtures are affected, the freeze is likely on a main supply line. If only one fixture is affected, the freeze is on the branch line serving that fixture.
Yes. The ice itself doesn't usually cause the burst — it's the water pressure that builds between the ice blockage and the closed faucet. This pressure can reach hundreds of PSI, enough to split copper, PEX, or steel pipes. The split may not leak until the ice melts, which is why some burst pipes aren't discovered until spring in vacant homes.
Keep your thermostat at 15°C or higher even when away. Open cabinet doors under sinks on exterior walls. Let faucets drip during extreme cold snaps. Insulate pipes in crawl spaces and exterior walls. Install heat cable on vulnerable pipe sections. For the best protection, book our winterization service before November.
Thawing a frozen pipe before it bursts typically costs $200–$350. If the pipe has already burst, repair adds $300–$500+ depending on the pipe material, location, and extent of damage. Water damage restoration from a burst pipe can cost $5,000–$25,000+. Thawing early is always the cheaper option.
