Pool Leak Detection in Langley, BC
GPR traces the buried plumbing loops around your pool so pressure testing and acoustic work isolate the leaking line without tearing up the deck. Serving Langley and the Fraser Valley region with certified technicians, non-invasive methods, and insurance-ready documentation — since 1999.

Langley ground conditions & what they mean for GPR
Local geology: Langley sits on rolling till with gravel outwash channels and Nicomekl lowland silts. Till and gravel scan 2–3 m cleanly across most of the township; lowland silt pockets shorten range locally.
Local building stock: Acreage estates with wells, septic, and undocumented private lines; Willoughby's dense new subdivisions; horse properties with buried water runs.

How the Langley site visit works
- 1
Evaporation test
Bucket test rules out normal evaporation (0.3–0.6 cm/day in BC summer) before any equipment is deployed.
- 2
Loop isolation
Each return, skimmer, and main-drain line is plugged and pressure-tested independently — the failing loop identifies itself.
- 3
GPR trace
The failing loop is traced under the deck with GPR, because pool plumbing rarely runs where anyone remembers.
- 4
Acoustic pinpoint
The leak is pinpointed along the traced line; one deck cut or one fitting repair instead of slab demolition.
Langley questions, answered
Do you have to drain the pool?
Almost never. Loop isolation, GPR tracing, and acoustic confirmation all work with the pool full. Draining is reserved for rare structural shell investigations — and draining a pool in high-water-table areas of BC can itself damage the shell.
The deck is stamped concrete — will you cut it?
Only after the leak is pinpointed, and only a single small opening at the marked point. GPR tracing exists precisely to avoid the old practice of chasing pool lines with a saw.
Our strata pool loses chemicals fast but the level looks stable. Leak?
Possibly — auto-fill systems mask water loss while the chemical bill and heating cost climb. We isolate the auto-fill, run the loss test properly, and find what the top-up was hiding.
Can you check hot tubs and swim-spas too?
Yes. Most spa leaks turn out to be union fittings at the pump or heater rather than the shell — a 30-minute confirmation that saves replacing a tub.
How deep can GPR scan in Langley?
Langley sits on rolling till with gravel outwash channels and Nicomekl lowland silts. Till and gravel scan 2–3 m cleanly across most of the township; lowland silt pockets shorten range locally. We select antenna frequency to match — and where local ground limits radar depth, we pair GPR with electromagnetic locating, acoustic methods, or tracer gas so the survey objective is met regardless of soil conditions.
Do you actually work in Langley, or dispatch from elsewhere?
Langley is part of our standing Fraser Valley service area — the same certified technicians and equipment that cover the rest of the region. Scheduling is typically within 24–72 hours, with same-day response often possible during business hours (Mon–Sat, 8am–6pm Pacific).
What does pool leak detection cost in Langley?
Pricing matches our province-wide structure — no regional premium for Langley. Most residential-scale work falls in the $350–$1,200 range depending on scope; commercial and multi-site projects are quoted after a free phone consult. Call 604-239-9934 and we will give you a tight estimate in five minutes.
