Hidden Water Leak Detection in Caledon

Standalone leak detection visits in the GTA run $295–$495. Same-day premium: +$50–$100. After-hours emergency: $400–$600. Includes 1–2 hours on-site, thermal camera scan, moisture-meter confirmation, photo documentation, and a verbal locate. Written PDF report add-on: $99 (often required for insurance claims). Caledon comparable: A Plus Plumbing $395 starting; John the Plumber $150–$400 range.

Yes — that's the entire point of thermal leak detection. The FLIR camera sees a cool zone (evaporative cooling from wet material) on the surface; the moisture meter reads moisture content up to 3/4 inch depth without piercing the surface. Together they identify wet zones non-destructively. Once located, we (or the customer's plumber) open only the precise area needed for repair — not exploratory demolition.

Same-day visits are available 7 days a week for active leaks. Standard scheduling 2–4 business days. Call 289-212-2345 — leak detection is our highest-priority call type.

Yes — our PDF reports are formatted for adjuster review and accepted by major Canadian insurers (Intact, Aviva, TD, RSA, Co-operators) as supporting evidence on water-damage claims. Always notify your insurer before commissioning a scan — many will pre-approve the inspection cost. For full IICRC-grade restoration documentation, we partner with certified restoration providers.

Some leaks are intermittent (only when the dishwasher runs, only after a heavy rain, only when the ice-maker cycles). For these, we recommend either timing the visit to coincide with the suspected trigger, or doing a baseline scan now and a follow-up scan during the trigger event. Intermittent leaks are harder but not impossible — moisture often persists in materials for hours-to-days after the active leak event.

Yes — RenoHouse holds Ontario plumbing licensing through partner trades, and we scope the repair on the same visit for most common Caledon leak sources (shower pan, supply line, drain, eavestrough). For sewer-line or main-stack work we refer to specialist plumbers. Same-day repair scheduling is common; 60–80% of our leak-detection visits convert to a plumbing + restoration repair contract.

Very accurate when the leak is active or the affected material is still wet. We typically locate the source within an 18-inch zone, often within 6 inches once moisture-meter readings narrow it down. Accuracy drops for very small leaks (pinholes), intermittent leaks, and leaks where the wet zone has dried before our visit.

Partial. Thermal can detect sewer leaks where wastewater is wetting drywall or subfloor and creating a thermal signature. Thermal cannot detect sewer-line cracks underground without surface symptoms — that requires a sewer-line video camera (we partner with specialist providers for video inspection).

Slab leaks are detectable when the leaking water warms (or cools) the slab surface enough to create a thermal anomaly. Most reliable for hot-water supply lines (where the warm-water leak shows as a hot zone on cooler concrete). Cold-water slab leaks are harder. We can typically locate a slab leak within a 1–2 ft zone — accurate enough for targeted concrete coring.
