Hidden leaks behind walls, under floors, and in ceilings can cause thousands of dollars in damage before you even know they're there. We use professional detection equipment to pinpoint leaks without tearing your home apart — then fix them right.
North Bay Plumbers provides professional leak detection and repair services across North Bay, Callander, and Sturgeon Falls. Using acoustic listening equipment, thermal imaging, sewer cameras, and pressure testing, we locate hidden leaks behind walls, under concrete slabs, and in ceiling cavities without destructive exploratory cutting. Leak detection typically costs $250–$600 including the repair for most residential leaks. Early detection prevents mould growth, structural damage, and water bills that can run into thousands. Call 705-482-1253.
These warning signs often go ignored for weeks or months — but every day a hidden leak goes undetected, the damage compounds. If you're noticing any of these, call us before the problem gets expensive.
We follow a systematic process that starts simple and escalates only as needed — so you're never paying for equipment or time that isn't necessary.
We start with a thorough visual check of all exposed plumbing, fixtures, water heater, and utility connections. Many leaks are found at accessible joints and valves before advanced equipment is needed.
We isolate and pressurize sections of your plumbing system to confirm a leak exists and narrow down which section it's in. If pressure holds, there's no leak — simple and definitive.
For hidden leaks, we use acoustic listening equipment to hear water escaping inside walls or under slabs, thermal imaging to detect temperature differences from moisture, and sewer cameras for drain line leaks.
Once we've located the leak to within inches, we make the smallest possible access point. No unnecessary drywall removal or floor cutting. Targeted access means less repair work after.
We repair the leak, re-pressurize to confirm it's sealed, and verify with a follow-up check. We'll also flag any other areas that show early signs of potential leaks.
North Bay's climate and housing stock create specific leak risks that homeowners should understand. Here's what we see in the field every week.
North Bay's extreme temperature swings — from -35°C in January to +30°C in July — put constant stress on pipe joints and fittings through expansion and contraction. This freeze-thaw cycling loosens connections over time, creating slow leaks that may not show symptoms for months.
Some homes in West Ferris and downtown North Bay have water lines running under the concrete slab foundation. When these copper lines corrode or shift, they leak under the slab — invisible from above but detectable with thermal imaging and acoustic equipment.
During March-April spring melt, many North Bay homeowners see moisture in their basements and assume it's groundwater. Sometimes it is — but sometimes it's a slow plumbing leak that's been masked by seasonal moisture. We can tell the difference.
Ontario homeowner insurance typically covers sudden leak damage but NOT gradual damage from undetected leaks. A small leak that goes unnoticed for months can cause mould growth behind walls — a health hazard and a renovation nightmare. Early detection is the cheapest insurance you can buy.
We believe in transparent pricing. Here's what professional leak detection and repair typically costs for residential properties in North Bay.
We use three non-invasive methods: acoustic listening equipment that amplifies the sound of water escaping through pipes, thermal imaging cameras that detect temperature differences caused by moisture, and pressure testing that isolates which section of pipe is leaking. We only open walls once we've pinpointed the exact location.
Professional leak detection in North Bay costs $250–$400, with most repair-inclusive jobs running $350–$600. Complex situations like slab leaks or multi-story buildings may cost more. We quote after assessment and never charge for detection if we can't find the leak.
Yes. A leak as small as one drip per second wastes over 11,000 litres of water per year and can cause mould growth within 48 hours in the right conditions. Behind-wall leaks that go undetected for months can compromise structural framing, destroy insulation, and require extensive renovation.
Absolutely. An unexplained water bill increase is the #1 indicator of a hidden leak. Even a small increase of $20–30/month could indicate a significant leak somewhere in your system. We can usually locate the source within an hour.
Both. We handle detection and repair as one service. Once we locate the leak, we repair it on the same visit in most cases. For complex situations (slab leaks, main line issues), we may need to schedule the repair — but we'll give you a complete plan and quote before leaving.
