Leak detection for Toronto homes, before it becomes a bigger job
A damp spot on the ceiling or a rising water bill usually means something's leaking out of sight. We find it without tearing the house apart.

Where leaks tend to hide in GTA homes
A leak rarely shows up right where the water's actually escaping. Gravity and building materials move it somewhere else first.
Pinhole leaks in copper
Common in homes plumbed in the 1970s and 80s, where internal pipe corrosion eventually opens tiny leaks that spray rather than drip.
Slab leaks
Less common but present in some GTA homes with in-slab piping — usually shows up as an unexplained warm spot or rising water bill.
Under-fixture seepage
A toilet or tub surround that's leaked slowly for months, often only noticed once flooring or subfloor starts to show damage.
Exterior wall freeze damage
Pipes run too close to an exterior wall in older construction can crack after a hard freeze, only to leak once things thaw.
A small leak doesn't stay small
Water finds the path of least resistance — down into subfloor, along a joist, behind drywall — and by the time it's visible, it's often been active for weeks. Mould, warped flooring and weakened framing follow.
We trace it before we cut anything
Moisture meters, listening equipment, and a methodical process of elimination let us pinpoint the source with minimal opening-up. Once we know exactly where it is, the repair itself is usually the easy part.

Leak detection questions
How do you find a leak without cutting open my walls?
Moisture meters and listening equipment let us narrow down the source area first, so any opening we do is targeted rather than exploratory.
My water bill went up but I don't see any water. Could it still be a leak?
Yes. A rising bill with no visible sign is one of the most common early indicators of a hidden leak, often behind a wall or under a slab.
Are pinhole leaks common in Toronto homes?
In homes with original copper supply lines from the 1970s and 80s, yes. Internal corrosion over decades can eventually open small leaks.
Can freeze-thaw cause leaks that show up in spring?
Yes. A pipe can crack during a winter freeze and only start leaking once temperatures rise and the ice inside melts.
Do you repair the leak the same day you find it?
In most cases, once we've pinpointed the source, the repair itself can be completed in the same visit.
