We find the leak before we open your wall, not after
A rising water bill, a damp patch on drywall, a musty basement smell — we trace it to the source using equipment that doesn't require demolition to get an answer.

Where leaks tend to hide in Mississauga homes
Leaks rarely show up right where the damage is happening. Water travels along framing and pools somewhere convenient for it, not for you. Local housing patterns give us a good starting map.
Slab leaks in older bungalows
Some older Mississauga homes have copper supply lines running under a concrete slab. Those pipes corrode over decades, and by the time you notice a warm spot on the floor, it's been leaking a while.
Freeze-thaw damaged service lines
The line running from the street to your house shifts with ground movement every winter and spring. A slow leak there often shows up as unexplained soggy patches in the yard.
Behind-the-wall supply line failures
Newer builds use PEX, which is generally reliable, but a bad crimp fitting or a nail through the line during a reno can cause a slow leak that takes months to show a stain.
Roof and eavestrough related leaks mistaken for plumbing
GTA's mix of heavy spring rain and winter ice damming sometimes gets blamed on plumbing when it's actually water intrusion from above. We check both before assuming.
A hidden leak costs you twice — once in water, once in damage
An undetected leak wastes water every single day it runs, but the bigger cost is usually the damage it causes waiting to be found — soaked insulation, weakened subfloor, mould growth in a humid basement. In older Mississauga homes with less moisture-resistant materials, that damage accumulates faster than people expect.
Non-invasive detection, targeted repair
We use acoustic and pressure-based detection to narrow down a leak's location before opening anything. That means we're cutting into drywall or flooring only where the leak actually is, not exploring by trial and error.
How we track down a leak
Here's how the work actually unfolds, step by step.
- 1
Initial assessment
We review symptoms — water bill spikes, damp spots, sounds — to narrow the search area.
- 2
Non-invasive detection
Acoustic listening and pressure testing pinpoint the leak without opening walls or floors first.
- 3
Confirm and access
Once located, we open only the section needed to reach the pipe.
- 4
Repair and verify
We repair the leak and pressure-test the line again before closing anything back up.

Leak detection & repair FAQs
How do you find a leak without tearing open my walls?
We use acoustic listening devices and pressure testing to narrow the location first. Only once we've confirmed roughly where the leak is do we open anything, and even then it's a targeted section, not a search pattern.
My water bill went up but I don't see any water — could it still be a leak?
Yes, this is one of the most common signs of a hidden leak, especially a slab leak or a service line leak in the yard. Worth investigating before it gets worse.
Is a damp basement always a plumbing leak?
Not always — in the GTA, basement moisture is often groundwater or foundation seepage rather than a pipe. We check for plumbing sources first since that's our trade, and can tell you if it looks more like a foundation or drainage issue.
How much wall or floor do you need to open to fix a leak?
As little as possible. Once detection narrows the location, we open only the section needed to reach and repair the pipe.
Can a leak in the yard really affect my water bill that much?
Yes — a service line leak underground can run for weeks unnoticed, and depending on the size of the crack, it adds up fast on a water bill.
