Think you might have a hidden water leak Toronto homeowners dread? Watch for these common warning signs:
Persistent smells or dark patches often mean moisture is trapped behind walls or under floors.
These are classic signals of moisture inside the structure—often a cue for ceiling leak repair Toronto homeowners need quickly.
Hear hissing or trickling in the walls? That’s a red flag for an active leak.
A high water bill without a usage change usually points to hidden water loss.
Heat from a hot-water line or moisture under flooring can give leaks away.
In high-rises, a small leak can travel between units—act fast.
If you notice any of these signs, book leak detection right away. For urgent issues, call our emergency plumbing team, or contact us to schedule a same-day visit.
We use smart, non-destructive tools to locate leaks fast—so your walls and floors stay intact. Our methods are accurate, clean, and ideal for homes and condos across Toronto.
Our cameras spot heat and cold patterns behind walls and ceilings. Thermal imaging leak detection Toronto is great for radiant heating, hot-water lines, and hidden pipe leaks. We see the clue, then confirm the source before we open anything.
With acoustic leak detection Toronto, sensitive microphones “hear” pressurized water escaping through concrete, drywall, or soil. We compare readings to zero in on the exact spot, even in noisy spaces.
A pressure test checks the health of your lines and fixtures. When needed, we add a dye test or tracer to isolate zones and prove where the leak is coming from. This keeps the search tight and the repair small.
If drains or stacks are the problem, we run a CCTV drain inspection to see inside your pipes. The camera reveals cracks, blockages, or misaligned joints. If we find damage, we’ll explain options and can coordinate pipe repair or replacement. For related issues like slow drains or backups, see drain cleaning or sewer backup service.

Toronto homes and condos share a few repeat offenders. Here’s what our team finds most:
Pinhole copper corrosion / failed PEX fittings
Tiny “pinhole leak” openings or cracked fittings can drip behind walls for months. If damage is found, we handle pipe leak repair in Toronto quickly and cleanly.
Freezing or freeze–thaw expansion
Exterior and uninsulated lines can split during cold snaps. See our frozen pipe repair service if you notice reduced flow or water stains after a thaw.
Aging cast-iron or galvanized stacks
Old stacks rust, pit, and crack, leading to slow leaks and stains on ceilings or walls.
Condo risers & unit-to-unit penetrations
Leaks can travel between suites through chases and shared risers; we coordinate access with building management.
Shower pans, tub drains, and toilet seals
Worn gaskets and failed caulking let water slip under tile. We can also help with toilet repair/installation when seals fail.
Foundation/slab seepage & yard lines
Underground lines and slabs may require slab leak detection Toronto homeowners can rely on to pinpoint the source before repairs.
If you see stains, smell musty odours, or your bill jumps, book leak detection today.

Toronto homes and buildings have unique leak risks. In older neighbourhoods, clay and cast-iron stacks can corrode behind shared walls, leading to slow, hidden leaks. Downtown condos face different challenges: tight access windows, noise limits, and building water shut-offs. Our team handles condo leak detection Toronto residents rely on—we coordinate with property managers to keep things smooth and fast.
Local weather matters too. Freeze–thaw cycles and sudden temperature swings can stress exterior lines and fittings. High-rise pressure zones and mixing valves can mask symptoms or push water to unexpected places. After heavy rain, drain stacks can surge; that’s when a CCTV drain inspection helps confirm if a blockage or crack is causing water to travel. If backups or slow drains appear, see our sewer backup service.

How much does leak detection cost in Toronto depends on access (behind tile, ceilings, slab), the method used (thermal, acoustic, pressure/dye), building type (house vs. condo), and severity. We inspect first, explain options, and give an upfront quote before any work.
Usually, yes. We often fix fixtures, supply lines, traps, and valves on the spot. Larger jobs (permits, parts, or bigger pipe sections) are scheduled through our pipe repair & replacement team, with clear timelines.
