Find the Leak Before It Finds Your Drywall
Hidden water leaks cause mold, structural damage, and thousands in repair costs before the first visible stain appears. We locate leaks without tearing up walls, then repair them the right way.
Your Home May Have a Hidden Leak If...
Most water leaks aren't immediately visible. By the time you see a water stain, the damage behind it has often been developing for weeks or months. Early signs are subtle — and easy to dismiss as something else.
- Water bill higher than usual with no change in usage habits
- Musty odour in basement, crawlspace, or walls
- Soft spots or discolouration in drywall, ceilings, or floors
- Water meter running when all fixtures are off
- Low water pressure in one or more areas of the home
- Hissing sound behind walls or under floors when water is off
Where Water Hides in Calgary Homes
Slab Leaks
Copper supply lines running through or under your concrete slab can develop pinhole leaks from Calgary's hard water chemistry. We use acoustic detection and pressure testing to locate slab leaks precisely — avoiding unnecessary concrete cutting.
In-Wall & Ceiling Leaks
Leaking supply lines, drain connections, or failed appliance supply hoses inside finished walls. Moisture meters and thermal imaging let us identify the wet zone before opening drywall — limiting the repair footprint.
Underground Supply Line Leaks
The water main between the street and your home can develop leaks from ground movement, freeze-thaw cycles, or pipe corrosion. Signs include wet yard, unusually high bills, and pressure drops. We locate and repair or replace the affected run.
Moen Flo Smart Water Monitor — Stop the Next Leak Before It Starts
We install the Moen Flo smart water monitor — it detects micro-leaks and automatically shuts off your water supply if it detects unusual flow. Ask us about installation at your leak repair appointment.
Leak Detection Questions
How do you find a leak without opening all my walls?
We use a combination of acoustic leak detection (listening for water movement through pipe walls), moisture meters (detecting elevated moisture content in building materials), and pressure testing (isolating sections of piping to locate pressure loss). Thermal imaging is used when moisture gradients are present. These methods let us narrow the leak to a specific area before any drywall is opened — typically limiting the access hole to one or two locations.
Should I repair or repipe after a slab leak?
If the affected pipe is copper and the home has had one slab leak, the rest of the copper run is at similar risk — especially in Calgary's hard water environment. A single repair is appropriate for an isolated incident. Two or more leaks from the same pipe run, or confirmed pinhole corrosion in multiple locations, typically justifies repiping (rerouting above-slab or through walls) rather than continuing to chase individual failures.
Will my home insurance cover a water leak?
Coverage depends on your policy and the nature of the leak. Sudden, accidental water damage (e.g. a burst pipe) is generally covered. Gradual leaks resulting from deferred maintenance often are not. We can provide a written report documenting the cause and timeline of the leak — useful for insurance claims. We recommend calling your insurer before remediation work begins so they can assess the damage in place.
