Why Leak.ca
Foundation leak detection done right
Identify the source
We distinguish between foundation wall leaks, footer leaks, underground service line breaches, and groundwater infiltration — each requires a different repair.
Non-invasive diagnosis
Thermal imaging, acoustic, and GPR find the leak without excavating your foundation or removing finishes.
No exploratory digging
We pinpoint the leak location so excavation is targeted. No trenching across your yard looking for the source.
Insurance documentation
Comprehensive reports with findings and recommendations — accepted by all major BC insurers.

Signs you need a professional
Don't wait until minor issues become major losses.
Water in the basement
Is it a foundation wall leak, footer leak, or underground service line? Different sources need different fixes. We identify the actual source.
Foundation cracks with water
Not all foundation cracks leak. We determine which cracks are active and which are cosmetic — saving you unnecessary repair costs.
Underground service line entering foundation
The point where water, sewer, or gas pipes enter the foundation is a common leak source. We detect leaks at this critical junction.
Hydrostatic pressure
Groundwater pressure against foundation walls can force water through cracks and joints. We help identify the entry points for targeted waterproofing.
Sump pump running constantly
A sump pump that never stops suggests excessive groundwater. We identify whether it's a plumbing leak or natural groundwater.
Mold behind drywall in basement
Finished basements hide foundation leaks behind drywall. Thermal imaging finds the moisture without demolition.
How it works
What happens when you call
Simple, transparent, focused on getting you the answers you need.
- 01
Describe the water
Where is water appearing? After rain or constantly? Tell us the pattern and we'll determine the approach.
- 02
On-site diagnosis
We scan the foundation interior with thermal, test underground lines acoustically, and survey the exterior with GPR.
- 03
Source identified
We pinpoint the exact water entry point — crack, pipe penetration, footer leak, or service line.
- 04
Repair guidance
You receive a report with findings and repair recommendations — targeted to the actual source.
Real outcomes
Recent foundation wins
Basement water mystery solved — it was the service line
Homeowner had water in the basement after rain. Two waterproofers gave different diagnoses. We traced it to a cracked underground service line entering at the foundation — not a wall leak at all.
Retail basement leak found at pipe penetration
Retail store had water in storage basement. Thermal identified moisture tracking from a pipe penetration. GPR confirmed no underground pipe leak — just a failed seal at the foundation penetration.
Parkade wall water infiltration source identified
Strata had water weeping through parkade walls. Thermal + GPR identified a failed exterior waterproofing membrane — not a structural crack. Targeted repair saved $60K vs full excavation.

- Will leak detection damage my property?
- No. We use non-invasive technology like thermal imaging, acoustic sensors, and ground-penetrating radar. No drilling, cutting, or demolition required in most cases.
- Does insurance cover leak detection?
- Many policies cover detection costs when water damage is present. We provide detailed reports for your insurance claim documentation.
- How quickly can you respond?
- Same-day response is often available for urgent situations. Regular appointments are typically scheduled within 24–48 hours.
- What if you don't find a leak?
- You receive a comprehensive report confirming no active leaks were detected. This documentation is valuable for insurance, property sales, or peace of mind.
- How do you find foundation leaks without digging?
- We use thermal imaging to detect moisture patterns on foundation walls, acoustic testing on underground service lines, and GPR to identify subsurface water pathways.
