How Much Does Leak Detection Cost in New Westminster, BC?
Typical cost in New Westminster
$300
$100 low · $1,050 high
Per visit to locate and pinpoint one leak: call-out, detection equipment & a marked location — repair quoted separately · Updated July 2026
Finding a hidden water leak in New Westminster costs $100 to $1,050 installed, and most homeowners pay around $300 for one suspected leak in a single-family home. You're buying an answer, not a repair. A leak detection visit puts a mark on the wall, the floor, or the lawn and tells you which pipe is failing and how deep it sits — the fix is quoted after that, as its own job. BC prices range from a $99 call-out with a visual check to $1,000 for locating a leak under a concrete slab, and the gap between those two numbers is entirely about what equipment comes out of the truck.
Central-Metro rates put a New Westminster locate moderately above the BC average: $99 to $300 for the call-out and non-invasive check, $300 to $700 once acoustic gear goes on the wall, $400 to $1,000 for slab or underground. Density is the local cost driver, because parking, elevators and getting access to the suite below all add time to a job billed by the visit. A condo inspection visit is commonly priced around $179, and specialists cover the city from both sides of the river.

What's in the Price — and What Isn't
In the price
- The call-out and the technician's time on site
- A meter and isolation test to prove water is escaping and narrow down which system it's on
- A non-invasive sweep of the suspect area — visual, moisture readings, and listening gear
- Pinpointing and physically marking the location on the wall, floor, ceiling, or ground
- A verbal or written finding you can hand to whoever does the repair
- On some BC companies' terms, no charge at all if the source can't be located
Costs extra
- The repair itself, which is quoted once the leak has a location
- Opening walls, ceilings, or concrete to expose the pipe
- Drying, dehumidifiers, or mould remediation after a long-running leak
- Drywall, tile, flooring, or landscape repair over the access point
- A camera inspection of the drain line, which is separate work looking for a separate failure
This service ends with a mark and a diagnosis — nothing is removed, replaced, or hauled away. Get the finding in writing with photos and, for an underground leak, the depth. That single page is what lets you take the repair to a second contractor rather than accepting whatever number arrives from the one who found it.

What Moves the Price
- Who you call
- The widest spread in this whole trade. A general plumber treats the first visit as a call-out and publishes $29 to $120 for it. A BC firm that does nothing but leak detection starts a residential diagnostic at $349, because acoustic gear, thermal cameras, tracer gas, and radar are on the truck before anyone knocks.
- Where the leak is hiding
- An accessible under-sink drip is found by looking. A pinhole in copper behind tile, or a hot line under a slab, needs equipment and time — Victoria published rates put acoustic work at $300–$700 and slab or underground location at $400–$1,000.
- How the fee is structured
- Three models are all live in BC. One Vancouver company charges $120 plus GST and waives it if you proceed with the repair. A specialist charges nothing if it can't find the source. A North Shore shop charges a flat $99 to attend, waived for nobody. Ask which one you're booking.
- Which tool the job needs
- Acoustic gear listens for pressurized water escaping. Thermal imaging reads a temperature difference through a finish and is published at $300–$600. Tracer gas and ground-penetrating radar come out when the first two can't answer it, at $400–$800 and up.
- Timing
- One BC specialist publishes $150 for priority scheduling on top of its standard diagnostic. Booking the first available slot rather than the next-hour slot is one of the few discounts available on a visit this size.
- How many leaks there actually are
- Pricing assumes one source. A house with pinholes appearing at several elbows is not a detection problem — it's a pipe at the end of its service life, and the useful spend shifts from finding this leak to pricing the repipe.

How the Job Actually Goes
-
Triage on the phone
What's wet, when it started, whether it's worse when the hot water runs, and what the meter is doing. A good dispatcher works out from that call whether this is a call-out job or a full acoustic visit, and quotes accordingly.
Free
-
Meter and isolation test
Everything gets shut off and the meter is watched. Then branches are isolated one at a time — irrigation, hose bibs, the water heater — until the dial stops. This narrows the search area before any equipment is unpacked.
Part of the call-out, $29–$120 at general plumbers
-
Non-invasive sweep
Visual inspection, moisture readings through finishes, and acoustic listening along the suspect run. Pressurized water escaping through a small hole makes a specific noise, and the right headset hears it through drywall, tile, and concrete.
$99–$150 basic, $300–$700 for full acoustic work
-
Escalating the equipment
When acoustic isn't conclusive, thermal imaging reads the temperature difference a leaking hot line leaves behind a surface, and tracer gas or ground-penetrating radar handles buried and slab work. That escalation is what turns a $150 visit into a $700 one.
Thermal $300–$600; tracer gas or radar $400–$800+
-
Pinpointing and marking
The technician marks the spot and, on a buried line, the depth. Precision here is money: a leak located to within a hand's width means one small opening rather than an exploratory demolition someone has to pay to put back.
Included in the detection fee
-
The repair quote
Detection ends here. The fix — a fitting, a section of pipe, a slab break and patch, or a full repipe — is a separate scope with a separate price, and you're free to take the written finding to another contractor for it.
Separate; the diagnostic fee is credited back at some BC companies
Do It Yourself or Hire a Pro?
Doing it yourself
- The meter test costs nothing and answers the biggest question: shut every fixture, watch the dial, and movement means water is escaping somewhere past the meter
- A dye tablet in the toilet tank finds the most common invisible household leak for about a dollar
- Shutting the valve on the water heater, the irrigation line, or the outside bibs one at a time tells a technician which branch to start on and shortens a billed hour
- A hardware-store moisture meter is genuinely useful for deciding which of two walls to point a professional at
- Slab and buried leaks give you nothing to see, and guessing wrong means opening a floor for no reason
- A phone thermal attachment isn't the same instrument as a calibrated camera in trained hands, and a warm patch on a wall has several explanations
- Water travels along joists and under flooring, so the wet spot is often nowhere near the failed fitting
- Every day of searching is another day of water running, and hidden leaks damage a house slowly and expensively
Hiring a licensed pro
- Acoustic, thermal, tracer gas, and radar between them will find a leak that no amount of looking will
- The pinpoint is what limits demolition — the difference between one 30 cm access hole and a torn-out wall
- Several BC companies waive or credit the fee if you have them do the repair, or charge nothing if they come up empty
- A written location and photos give you leverage on the repair quote
- You pay for the diagnosis before you've paid for a single thing that stops the leak
- Specialist rates are three to ten times a general plumber's call-out for the same first hour
Our take: Run the meter test and the toilet dye test yourself tonight — that's twenty minutes and it decides whether you need anyone at all. Past that, hidden and underground leaks are an equipment problem, and paying $300 to $700 to know exactly where the pipe failed is far cheaper than paying a plumber to open walls until one of them is right.
Signs It's Time to Replace
- A water bill that climbed with no change in the household
- The meter dial creeping while every tap, toilet, and appliance in the house is off
- The sound of water moving in a wall at night when nothing is running
- A warm patch on a floor, which on a slab house usually means the hot line under it
- A stain on a ceiling or wall that dries, gets painted, and comes back in the same shape
- A musty smell in one room, one closet, or one corner of a crawlspace
- The hot water tank cycling more often than it used to, with no more showers being taken
How to Keep the Cost Down
- Do the meter test and the toilet dye test first. A running toilet flapper looks exactly like a hidden leak on the bill and costs a dollar to rule out
- Ask straight out whether the fee is waived or credited if you book the repair. One Vancouver company waives its $120 diagnostic that way, and it changes the real cost of the visit to nothing
- Ask what happens if they don't find it. At least one BC specialist charges nothing in that case, which is worth more than a lower headline fee
- Match the company to the problem. A visible under-sink drip doesn't need a $349 specialist visit; a leak under a slab is exactly what that $349 buys
- Book in normal hours. Priority scheduling is published at $150 extra by one BC firm, and a slow leak rarely gets meaningfully worse in two days
- Get the location, depth, and photos in writing, then price the repair with two contractors. The finding is yours — you paid for it
New Westminster Notes: Permits, Homes, Rates
Gas permits go through Technical Safety BC ($116 on a contractor permit, 2026); New Westminster runs its own plumbing desk at a $165 minimum for up to four fixtures.
Queen's Park and the streets above the quay hold some of the oldest houses in the province, with galvanized supply behind lath and plaster and a century of renovation joints between. Those fail as pinholes and weeps rather than bursts. The quay and Brewery District towers are the other city entirely: concrete, stacked suites, and water presenting three floors below where the pipe let go, investigated through a strata rather than by whoever noticed it.
Central-Metro rates, moderately above the BC average, with density adding time on site.
Questions to Ask Before You Hire
- What does the fee cover, and what's the hourly rate if the visit runs long?
- Which equipment will you bring — acoustic, thermal, tracer gas, radar?
- Is the fee credited against the repair if I go ahead with you?
- Do I pay if you can't locate the source?
- Do I get the location, the depth, and photos in writing?
- Are you locating only, or quoting the repair as well?
- Who is responsible if access holes get opened in the wrong place?
While the Plumber Is There
Call-out time is a big share of any bill — if one of these applies to your home, pricing it in the same visit usually beats a separate appointment.
If the meter keeps turning and the ground outside stays soft, the failure is out in the buried supply pipe. The locate is the first step of that job, and $300 to $700 spent here decides whether you're buying a spot repair or a full replacement.
A third pinhole in the same copper system stops being a detection problem. At that point the money is better spent pricing the whole system than finding one more failed elbow.
Water appearing after a shower or a load of laundry may be a drain letting go rather than a pressurized line. Different tools, different trade, and a much cheaper visit if that's what it turns out to be.
