Leak Detection Cost in Vancouver (2026 Pricing Guide)

How Much Does Leak Detection Cost in Vancouver?

If your water bill has spiked, you can hear running water with everything turned off, or there's an unexplained damp patch on a wall or floor, you likely have a hidden leak. The first step is finding exactly where it is — and that's what professional leak detection does. In 2026, leak detection in Vancouver typically costs $250 to $600 for a standard residential job, though simple cases can be less and complex underground or slab leaks can run higher.

As licensed plumbers serving Greater Vancouver, the HYDROPRO team uses non-invasive equipment to locate leaks precisely before any wall, floor, or ground is opened. This guide breaks down the real costs so you know what to expect.

Leak Detection Cost by Method (2026)

The price depends largely on the equipment and time required to find the leak. Here are realistic Vancouver cost ranges by method:

• Visual & basic inspection: $150–$300 — for accessible, visible leaks under sinks or at fixtures
• Electronic/acoustic leak detection: $300–$600 — sensitive microphones and amplifiers that "hear" water escaping pressurized pipes inside walls or under slabs
• Thermal imaging: $300–$550 — infrared cameras that detect temperature differences from escaping water
• Sewer/drain camera inspection: $250–$500 — a camera snaked through drain lines to find cracks, blockages, and leaks
• Slab leak detection: $400–$900 — combines acoustic and pressure testing to pinpoint leaks beneath a concrete slab
• Underground water service leak location: $400–$800 — locating leaks on the buried line between the city main and your home

Many plumbers charge a single detection or diagnostic fee that covers the visit and the equipment used, and some apply that fee toward the repair if you go ahead with the work.

What Affects the Cost of Leak Detection

Two leak detection jobs are rarely identical. These factors move the price up or down:

• Leak location: A leak under an accessible sink is far cheaper to find than one beneath a slab or buried in the yard
• Type of pipe: Older homes with galvanized steel or copper can be harder to assess than modern PEX systems
• Accessibility: Finished basements, tiled floors, and concealed pipe runs take more time and specialized gear
• Equipment required: A simple acoustic check costs less than a multi-tool slab investigation
• Time of day: Emergency or after-hours detection carries premium rates, similar to other plumbing service costs in Vancouver
• Property age: Pre-1980 Vancouver homes often have complex plumbing that requires more investigation

Detection vs. Repair: Two Separate Costs

It's important to understand that leak detection and leak repair are usually priced separately. Detection finds the problem; repair fixes it. Once the leak is pinpointed, repair costs depend entirely on what's found:

• Minor accessible pipe repair: $200–$500
• Concealed pipe repair (in-wall): $500–$1,500
• Slab leak repair: $1,500–$4,000+ depending on access and rerouting
• Underground water service line repair: $3,000–$8,000+ if excavation is required

This is exactly why accurate detection saves money — by pinpointing the leak, your plumber repairs only the affected area instead of guessing and opening multiple sections of wall or slab. Learn more about our leak detection and repair service.

Signs You Need Professional Leak Detection

Don't wait for visible flooding. Call for leak detection if you notice any of these warning signs:

• An unexplained increase in your water bill
• The sound of running water when all fixtures are off
• Damp spots, discolouration, or peeling paint on walls, ceilings, or floors
• A musty smell or visible mould growth
• Warm spots on the floor (a sign of a hot-water slab leak)
• Reduced water pressure throughout the home
• Your water meter advancing while no water is being used

How to Get an Accurate Leak Detection Quote

To make sure you're getting fair value, follow these steps:

• Describe the symptoms clearly — bill increase, sounds, damp areas — so the plumber can estimate the right method
• Ask whether the detection fee is applied toward the repair cost
• Confirm you'll receive a written report identifying the leak location
• Verify the company is licensed and insured in BC
• Ask for a separate repair estimate once the leak is located
