Why Leak.ca
Slab Leak leak detection done right
Three methods combined
Thermal imaging finds the temperature differential. GPR maps the in-slab plumbing. Acoustic confirms the pressurized leak. Combined accuracy within inches.
Small patch repair
We locate the leak within inches — your repair crew opens a 200-300mm patch, not half the slab.
Non-invasive
No drilling, no coring, no damage to your slab. All detection is done from the surface.
Insurance-ready reports
Reports include thermal imagery, GPR scans, acoustic data, and moisture maps — accepted by every major BC insurer.

Signs you need a professional
Don't wait until minor issues become major losses.
Warm spots on the floor
Hot water leaking under your slab creates warm patches on the floor surface — the #1 sign of a slab leak.
High water bills
A slab leak can waste thousands of litres per day. Your water bill shows it before you see any damage.
Musty smells from flooring
Moisture trapped between the slab and flooring creates mold and musty odours.
Cracks in the slab or tile
Water washing out soil beneath the slab can cause settling, leading to cracked tiles or foundation movement.
Insurance claims
Insurers need professional slab leak detection reports to approve water-damage claims and subrogation recovery.
Pre-sale or pre-purchase
Selling a home with a slab leak history? Or buying one? A professional slab scan gives everyone confidence.
