Leak detection suited to GTA housing

Hidden leaks behave differently depending on the home. Century properties with plaster walls hide leaks differently than newer builds with drywall and PEX manifolds, and our approach adjusts accordingly.

Freeze damage shows up in spring

A pipe stressed by a winter freeze sometimes doesn't show a visible leak until the spring thaw puts pressure back through the system.

Basement finishes hide slow leaks

Many GTA basements are finished, which means a slow leak can travel along a joist before ever showing on the ceiling below.

Acoustic and thermal detection

We use listening devices and thermal imaging to narrow down a leak's location before opening any wall or floor.

Targeted repair, not exploratory demolition

Precise detection means we open only what needs to be opened to reach the leak.

Leak detection suited to GTA housing
The problem

A hidden leak causes damage long before you see it

By the time a stain appears on a ceiling or a floor feels soft underfoot, a hidden leak has often been running for weeks or months. In GTA homes with finished basements or older wall assemblies, that moisture can travel a surprising distance from its actual source, making the visible damage misleading.

Our solution

We pinpoint it, then repair it cleanly

Using moisture meters, acoustic detection, and thermal imaging, we trace the leak to its real origin rather than opening walls based on a guess. Once located, we provide a written repair scope and photo-document both the leak and the finished fix.

Leak detection questions

How do you find a leak without cutting into walls?

We start with non-invasive tools like acoustic listening devices and thermal imaging to narrow the location before any cutting is needed.

My water bill went up but I don't see any water. Could it be a leak?

Yes, a rising water bill with no visible signs is a common indicator of a hidden leak, and it's worth having checked.

Do you repair the leak the same day it's found?

In many cases yes, once the leak is located and you've approved the written scope.

Can freeze damage cause a delayed leak?

Yes, pipe stressed during a hard freeze can develop a leak that only becomes apparent once things thaw, which is common across the GTA.

Will you patch the wall or floor you open?

We can coordinate the plumbing repair and discuss patch options, though finish work like painting is typically outside our scope.
