Concrete Slab Moisture Detection Metro Vancouver: Trusted BC Leak Detection Specialists Since 1999

Reviewed by Sophia L. Nakamura, Drone Inspection & Thermography Specialist | Transport Canada Advanced RPAS pilot, Level II Thermographer, 9 years drone-thermal experience | Published 2026-05-16 by AnyLeak.ca

Last quarter, an AnyLeak technician arrived at a Lake Country property on a Tuesday morning to investigate exactly the kind of question that brings people to a page like this one: a homeowner who suspected a leak but didn’t know where, how serious, or what to do about it. The investigation took under two hours; the pinpoint leak location was within 15 centimetres of the actual failed fitting; the repair scope was a fraction of what the homeowner had feared. This is the workflow you can expect when you engage AnyLeak.ca for Concrete slab moisture detection Metro Vancouver.

The cost of leaving a hidden leak undetected compounds non-linearly. Day one, you have a pinhole and minor moisture. Day thirty, the moisture has spread through framing and insulation, and mould has begun colonizing affected surfaces. Day ninety, structural members may be losing strength, finishes are warped, indoor air quality is degraded, and the repair scope has expanded from a small access cut to a major renovation. Concrete Slab Moisture Detection Metro Vancouver from AnyLeak.ca interrupts this trajectory. Our non-invasive diagnostics typically locate hidden leaks within hours of arrival, allowing repair to proceed before secondary damage becomes the dominant cost.

AnyLeak.ca has been British Columbia’s specialist for Concrete slab moisture detection Metro Vancouver since 1999. Our methodology is built around one simple commitment: we find the leak before we cut, lift, or excavate anything. Our diagnostic equipment — acoustic correlators, thermal imagers, tracer gas, hydrophones, ground penetrating radar, permanent monitoring loggers — allows us to pinpoint the leak source through finished walls, painted surfaces, suspended ceilings, finished flooring, and even poured concrete slabs. The result: minimal building disruption, surgical repair scope, and the lowest total cost to your wallet and your nerves.

Recent Case Study: Whistler Village, 2024

Property type: Boutique hospitality property
Initial scenario: Domestic hot-water recirculation leak under main floor
Detection method: Thermal imaging + tracer gas
Outcome: Located behind a custom-tile feature wall; minimal-access cut preserved finish.

This engagement reflects the kind of work AnyLeak performs routinely across British Columbia. Specific client identities are kept confidential, but the pattern is representative of hundreds of similar investigations in our 25-year BC track record. The methodology applied here — Thermal imaging + tracer gas — is appropriate for the asset type and is consistent with industry best practice for non-invasive leak detection on this category of property.

Roof and Building Envelope Leak Detection

Many building leaks that present as interior plumbing failures are actually building-envelope leaks: roof penetrations, parapet flashings, window head flashings, balcony waterproofing failures, or stucco/EIFS defects. Tracing the actual leak path requires understanding water entry points at the exterior and migration patterns through the envelope. AnyLeak combines exterior visual inspection, drone aerial survey of rooftops and parapets, thermal imaging from both interior and exterior, and where appropriate, water spray testing to reproduce the leak under controlled conditions. We coordinate with roofing contractors, envelope consultants, and waterproofing specialists for the repair scope.

Non-Invasive vs. Destructive Investigation

The traditional response to a building leak — open walls, lift flooring, demolish ceilings — is both expensive and unreliable. Destructive investigation rarely finds the leak on the first opening; the technician must then open more areas, expanding damage at each step. AnyLeak reverses this: we deploy diagnostic equipment first, pinpoint the leak through finished materials, verify with a second method, and only then recommend a single targeted access cut. The economic difference is often a factor of 5–10× lower total cost compared to destructive testing, with proportionally less occupant disruption and finish damage.

Underground Pipe Leak Detection

Buried service laterals — the supply line from the municipal connection to the building — are among the most common hidden leak locations. Pre-1980 copper, galvanized steel, and older PVC service lines develop pinhole corrosion, joint failures, and mechanical damage that result in slow leaks deep in trench backfill. The water rarely surfaces; it migrates along the trench, surfaces at low points blocks away, or never surfaces at all. AnyLeak’s underground leak detection uses acoustic correlation between the meter and the building entry, ground microphones for surface listening, hydrophones for non-metallic lines, and GPR to locate the pipe and identify saturated soil zones around the suspected leak.

The Role of Moisture Mapping and Drying Verification

Finding the leak is only the first step. AnyLeak’s investigations also document the spatial extent of moisture intrusion using pin and pinless moisture meters, hygrometric measurements, and IR thermography. This moisture map informs the restoration scope: which materials must be removed, which can be dried in place, and which require monitoring for mould risk. After restoration is complete, AnyLeak offers verification visits to confirm that drying targets have been met and no residual moisture remains — a service insurance adjusters and restoration contractors frequently request as proof of remediation.

Foundation and Basement Leak Investigation

Foundation leaks can be subsurface (water entering through wall or floor cracks from groundwater pressure), domestic plumbing (a buried supply line entering the building through the foundation wall), drainage (a perimeter drain or weeping tile failure), or service-related (a sewer line leak saturating soil around the foundation). Each category requires a different diagnostic approach. AnyLeak’s foundation investigations begin with a thermal survey of the affected wall, followed by moisture mapping, hydrostatic pressure assessment, dye testing of suspected drainage paths, and where indicated, ground penetrating radar to locate buried utilities and voids.

High-Rise and Multi-Storey Investigation Strategies

High-rise buildings concentrate hidden-leak complexity. Multiple risers, dozens of horizontal branches, hundreds of units, fire-suppression standpipes, HVAC chilled and condenser water, and domestic hot-water recirculation all share vertical and horizontal pathways through the building. A leak in unit 1404 may surface in unit 1102, two floors below and three units over. AnyLeak’s high-rise investigations begin with mechanical drawing review, followed by systematic riser isolation testing, acoustic survey of mechanical rooms, thermal imaging of affected units, and tracer gas where complex multi-pipe arrangements require positive identification.

Slab Leaks: The Specialty Within the Specialty

Leaks under poured concrete slabs are one of the most difficult categories of hidden leak. Slab-embedded copper supply lines, hot-water recirculation loops, radiant heating systems, and snowmelt systems all run through concrete that conceals failures completely. Without specialized equipment, the only options are to break the slab or shut off systems and guess. AnyLeak’s slab-leak methodology uses acoustic correlation to listen for leak sound through concrete, thermal imaging to map temperature differentials on slab surfaces, and tracer gas to confirm the leak’s exact position before any concrete is broken. Pinpoint accuracy is typically within 15 centimetres, allowing a single small access cut rather than full-floor demolition.

How Hidden Leaks Form and Why They Stay Hidden

Most building leaks start small. A pinhole in copper. A failed solder joint. A corroded fitting on galvanized steel. A cracked PEX line nicked during construction. A loose compression fitting on a fixture supply. In each case, the initial flow rate may be measured in drops per minute — small enough to be absorbed by surrounding building materials without surface evidence. As insulation, framing, and drywall saturate, the moisture migrates along the path of least resistance, often surfacing far from the leak source. The visible symptom — a damp spot, a paint blister, a musty smell — is the end of a long journey. AnyLeak’s job is to trace that journey backwards to the true source.

Water Penetration Testing for Building Envelope Leaks

For envelope leaks where the entry point is unclear, AnyLeak conducts controlled water penetration testing: directing water onto specific exterior elements under controlled flow rates while monitoring the interior for water entry. This methodology — aligned with AAMA and ASTM standards — identifies the precise envelope deficiency causing the leak. It is particularly useful for newer buildings where warranty claims require documented identification of the deficiency, and for older buildings where multiple envelope conditions complicate diagnosis.

When to Suspect a Hidden Leak

Common signs that warrant immediate investigation include: unexplained water-bill increases, audible water sounds when no fixtures are running, the sound of running water at the meter when shut-off valves are closed, mould-like odours in a previously dry space, warped or stained flooring, paint blisters or bubbling on walls or ceilings, increased humidity in basement or crawl space, warm spots on tile or concrete floors (indicating hot-water slab leaks), and unexplained increases in heating bills. Any of these warrants a professional Concrete slab moisture detection Metro Vancouver investigation. The earlier the diagnosis, the lower the cumulative damage.

Wall and Ceiling Leak Detection

Leaks inside wall cavities and above ceilings present a different challenge: the leak source is often far above or beside the visible wet spot. Water travels along studs, joists, and electrical conduit, dropping vertically when it encounters obstacles. AnyLeak’s wall and ceiling investigations begin with a thermal imaging survey to map moisture distribution, followed by acoustic listening to identify pressurized-pipe leak signatures, and concluded with moisture mapping to quantify the extent of intrusion. We trace the leak backwards from the visible symptom to the actual pipe source, then recommend a minimal access cut at the source location only.

Documenting Hidden Leak Investigations

AnyLeak’s hidden-leak investigations produce documentation suitable for insurance claims, strata council reporting, capital planning, and litigation support where needed. Every report includes pinpoint leak location with building-drawing markup, photographic evidence, thermal imagery, instrument readings, estimated leak duration based on damage extent, recommended repair scope, and follow-up verification recommendations. For multi-unit residential and commercial properties, our reports are formatted to support cost-allocation decisions between owners, property managers, and the strata or condominium corporation.

Equipment Spotlight: FLIR E96 thermal imager

Operators are certified on each device and undergo annual refresher training. Equipment is refreshed continuously as new diagnostic generations become available.

What Our Clients Say

“AnyLeak responded to our after-hours priority at our warehouse within two hours. The technician arrived calm, professional, and equipped. The leak was located before midnight.”

— David L., Annacis Island

Like David L., hundreds of BC property owners, strata corporations, commercial managers, and industrial operators have engaged AnyLeak.ca for leak detection investigations since 1999. Our consistent diagnostic methodology, transparent reporting, and professional conduct on site are why clients return across multiple investigations spanning years.

AnyLeak’s Four-Stage Investigation Process

Stage 1 — Intake and Scoping. Our coordinator reviews your situation, gathers building or site information, identifies prior leak history, and provides a written quote — typically promptly of contact.

Stage 2 — On-Site Investigation. Certified technicians arrive with a complete equipment kit. We begin with non-invasive methods (acoustic survey, thermal imaging) and escalate to tracer gas or GPR only as the case requires.

Stage 3 — Pinpointing and Verification. Once a suspected leak zone is identified, we verify with a secondary method (e.g., acoustic correlation confirmed by thermal imaging or tracer gas) to eliminate false positives. Pinpoint accuracy is typically within 15 centimetres on most pipe types.

Stage 4 — Reporting and Follow-Up. You receive a detailed PDF report containing site photos, thermal images, leak location markup, equipment data, recommended repair scope, and a clear next step. We remain available for repair coordination and post-repair verification.

How AnyLeak Compares to Other BC Leak Detection Providers

British Columbia has many leak detection providers, but the depth of capability varies widely. Some providers offer basic acoustic listening with limited equipment; others position themselves as full diagnostic specialists. AnyLeak occupies the latter category, with a track record and equipment library that few BC competitors can match. The distinction matters because the choice of leak detection provider directly determines repair cost, occupant disruption, and time to resolution.

Equipment depth. AnyLeak operates every major detection technology in a single integrated kit: acoustic correlation (AquaScan 620L), permanent monitoring (Gutermann Zonescan), hydrophone sensors, thermal imaging (FLIR), tracer gas, ground penetrating radar, drone aerial inspection, and moisture mapping. Many competitors offer only acoustic listening or only thermal imaging — and miss leaks that require alternative methods. Our multi-method approach is the difference between consistently finding the leak and repeatedly failing.

Experience. AnyLeak has been a BC leak detection specialist since 1999 — over 25 years and counting. We have accumulated thousands of investigations across residential, strata, commercial, industrial, government, and municipal infrastructure. Many BC competitors have been operating for less than a decade and lack the pattern recognition that comes from quarter-century exposure to local building stock, soil conditions, and failure modes.

Documentation. AnyLeak’s reports are designed to satisfy insurance, strata cost-allocation, government procurement, and capital-planning expectations. Our deliverables include photo evidence, thermal imagery, equipment data logs, leak location markup on building drawings, and clear repair recommendations. Many competitors deliver a verbal summary and a one-page invoice; the difference becomes apparent the moment an insurance adjuster, strata council, or capital-planning officer requests evidence.

Methodology. AnyLeak verifies every suspected leak with a secondary detection method before reporting. This eliminates false positives and ensures repair crews are deployed to actual defects. Competitors who skip verification deliver reports that occasionally point to the wrong location — costing the client repeat investigation and unnecessary destructive testing.

Long-Term Leak Prevention and Maintenance Programs

Finding and repairing an active leak is reactive. Preventing the next leak is proactive — and almost always more economical. AnyLeak offers preventive programs structured to the property type and risk profile. For BC property owners committed to a maintenance posture rather than crisis response, these programs deliver meaningful value year over year.

Annual inspection programs establish a baseline of building plumbing condition, identify early-stage issues before they become priority cases, and produce documentation that supports insurance positioning and capital reserve planning. Annual inspection is particularly valuable for strata corporations, commercial portfolios, school districts, and large institutional facilities — assets where the cost of an unexpected leak event is high.

Permanent acoustic monitoring deploys battery-powered Gutermann Zonescan loggers on hydrants, valves, and key pipe contact points. The loggers record nightly and flag new acoustic signatures consistent with leaks, often weeks before water becomes visible. For BC municipalities, large industrial sites, and mission-critical facilities, permanent monitoring is the most cost-effective continuous protection available.

Smart water monitoring integrates flow meters, pressure sensors, and acoustic loggers with the property’s building management system or cloud-based monitoring platform. Alerts are configured to email, SMS, or BMS alarms when consumption patterns suggest an emerging leak. AnyLeak supports clients deploying these systems with equipment recommendation, installation, commissioning, and ongoing data interpretation.

Post-repair verification visits confirm that detected leaks have been resolved and no secondary leaks have emerged. These visits are particularly valuable for insurance-claim work where proof of remediation is required, and for strata work where multiple stakeholders need confidence that the situation is fully resolved.

Many of our clients call us back across multiple investigations spanning years.

British Columbia Regulatory and Compliance Context

Professional leak detection in British Columbia operates within a layered regulatory environment that affects how investigations are scoped, conducted, and reported. AnyLeak.ca’s methodology is aligned with each applicable standard, and our reports document the alignment for downstream audit, insurance, and capital-planning use.

The BC Water Sustainability Act requires water utilities and large water users to report consumption and demonstrate stewardship. AnyLeak’s water-loss audits and infrastructure inspection findings feed directly into the data required by provincial reporting frameworks. Our reports are structured to support both annual provincial reporting and supplementary submissions for federal infrastructure-funding programs.

The BC Building Code and BC Plumbing Code establish construction standards that influence leak failure patterns by era. Pre-1980 copper supply lines, galvanized steel branches, asbestos-cement service lines, and early-generation PVC each have characteristic failure modes that experienced BC technicians recognize on first inspection. AnyLeak’s intake protocol identifies the likely failure profile based on building age and construction type before crews are dispatched.

WorkSafeBC Occupational Health and Safety regulations govern how leak detection contractors investigate active leaks, confined spaces, working at heights, and conditions involving electricity-water interaction. AnyLeak maintains current safety programs, conducts site-specific hazard assessments, and provides documented compliance evidence on every engagement.

The Strata Property Act and the Real Estate Council of BC rules govern multi-unit residential investigations where ownership boundaries and cost-allocation must be determined. AnyLeak’s reports identify leak locations with sufficient precision to support correct attribution under each corporation’s bylaws. We do not provide legal interpretation, but our technical evidence base supports the strata council and their counsel in making defensible decisions.

For insurance-related engagements, the Insurance Bureau of Canada’s standards for water-damage claim documentation inform our report format. AnyLeak’s reports include the pinpoint leak location, leak duration estimate, recommended remediation scope, and supporting evidence that BC insurance adjusters expect when adjudicating water-damage claims. Many BC adjusters know AnyLeak by reputation and accept our reports as primary evidence in claim files.

The Science Behind Our Detection Methods

The diagnostic methods AnyLeak.ca deploys are grounded in physics, engineering, and decades of field validation. Understanding the underlying science helps property owners and managers appreciate why multi-method investigation reliably outperforms single-tool approaches.

Acoustic leak correlation uses the fact that pressurized water escaping from a leak produces a characteristic sound spectrum that propagates through the pipe wall in both directions from the leak point. The frequency content depends on pipe material, diameter, internal pressure, and leak size — metallic pipe transmits higher-frequency content efficiently, while plastic pipe attenuates these frequencies. By placing two acoustic sensors at contact points spanning the suspected leak, computing the cross-correlation of their recorded signals, and applying the known acoustic propagation velocity for the pipe material, AnyLeak’s correlators calculate the leak position with sub-metre accuracy on most metallic pipe configurations.

Thermal imaging detects surface temperature differentials caused by water leaks behind finished materials. A hot-water leak warms the surrounding wall, slab, or ceiling slightly; a chilled-water leak cools it. Calibrated infrared cameras with sub-degree (typically 0.05 K) sensitivity resolve these differentials and produce thermograms that map the spatial extent of moisture intrusion. Thermal imaging is particularly powerful on radiant heating systems and slab-embedded plumbing where direct access is impossible.

Tracer gas detection relies on hydrogen’s extreme mobility. AnyLeak introduces a non-toxic, non-flammable 5% hydrogen / 95% nitrogen mixture into depressurized piping. The gas escapes through the leak point, diffuses through soil or building materials at a much higher rate than air, and is detected at the surface with a handheld sniffer. Tracer gas is the gold standard for radiant heating loops, swimming pool plumbing, and complex multi-pipe systems where acoustic methods are limited.

Ground penetrating radar (GPR) transmits high-frequency electromagnetic pulses into the subsurface and measures the reflections from buried materials. Different materials produce different reflection signatures, allowing GPR to image pipes, voids, saturated soil, rebar, and other features. AnyLeak deploys GPR for pipe location, depth verification, and excavation planning — particularly before any digging is committed.

Hydrophone sensing overcomes the acoustic attenuation problem on non-metallic pipe. By inserting a high-sensitivity acoustic sensor inside the water column (at a hydrant, valve, or access point), AnyLeak captures leak signatures propagating in the fluid itself rather than relying on surface contact through pipe wall. This is essential for modern PVC, HDPE, and asbestos-cement distribution mains across BC municipalities.

Detection Technologies AnyLeak Deploys

Our technicians arrive with a layered diagnostic toolkit, applying the least invasive method first and escalating only as the investigation requires:

• AquaScan™ 620L cordless leak noise correlator — pinpoints pressurized-pipe leaks via cross-correlation acoustic analysis with sub-metre accuracy on metallic pipe
• Gutermann electronic ground microphones — surface-listening for buried service laterals and shallow distribution main leaks
• Hydrophone sensors — in-pipe acoustic detection for plastic and asbestos-cement pipes that don’t transmit leak sound at the surface
• FLIR thermal imaging cameras — calibrated infrared imaging that detects hot- and chilled-water leaks behind finished surfaces without invasive testing
• Tracer gas kit — safe 5% hydrogen / 95% nitrogen mixture introduced into depressurized lines, detected at the leak point with a handheld sniffer
• Moisture meters — pin and pinless meters confirming the spatial extent of moisture intrusion
• Ground penetrating radar (GPR) — pipe location, depth verification, void detection, and saturated-soil mapping prior to any excavation
• Gutermann Zonescan permanent monitoring — for chronic or intermittent leaks where one-time inspection cannot reliably capture the signature
• Drone with thermal payload — rooftop, parapet, exterior envelope, and large-site aerial inspection

All equipment is calibrated annually with certificates available on request. Technicians complete recurring training on each instrument.

Real-World BC Case Studies and Outcomes

Twenty-five years of British Columbia leak detection has produced a portfolio of representative engagements that illustrate the value AnyLeak.ca delivers. While project-specific details remain confidential, the outcome patterns are consistent and instructive.

Metro Vancouver strata complex, 1980s wood-frame. Recurring leaks in upper-floor units had prompted four separate plumbing investigations over two years, each ending in exploratory wall openings that found no leak. AnyLeak’s acoustic correlator and thermal imager located the actual leak in a vertical riser 4 metres horizontally from the visible damage on the second site visit. Total AnyLeak engagement: $1,650. Total prior failed-investigation cost: estimated $11,000. Avoidable ongoing water damage: substantial.

Fraser Valley industrial cold-storage facility. A consumption variance investigation revealed an additional 4,200 litres per day above baseline. AnyLeak deployed acoustic logging on the incoming service line and located a pinhole leak on a 60-mm copper main entering the building. Repair cost: $1,200. Annual water savings: roughly $5,400. Annual energy savings on refrigeration load not having to cool wet insulation: estimated $3,800. ROI within the first quarter.

Vancouver Island municipal distribution network. A coastal community with 75 km of distribution main reported a 32% non-revenue water rate. AnyLeak’s six-week survey identified 47 individual leaks, totalling an estimated 6.3 L/s of continuous loss. Repair of the top 20 leaks reduced non-revenue water by 9 percentage points within six months — a roughly $310,000 annual saving on a survey investment of approximately $58,000.

Downtown Vancouver office tower, 1990s construction. A tenant complaint about ceiling water staining on the 18th floor triggered an investigation that revealed the actual leak was on the 22nd-floor mechanical room — a chilled-water expansion-tank fitting. AnyLeak’s thermal imaging and tracer gas located the source in 90 minutes after building management had spent three days unsuccessfully investigating closer to the tenant complaint. The repair was completed during the next maintenance window with no further tenant disruption.

Sustainability, Water Stewardship, and Environmental Impact

Every leak AnyLeak finds is water that does not have to be treated, pumped, and replaced. For British Columbia property owners, municipalities, and industrial operators, this translates directly to lower environmental impact, reduced operating cost, and meaningful contribution to provincial water-sustainability targets.

A typical pinhole leak operating at 60 psi loses over 3,000 litres per day. Across a year, that is more than a million litres — the equivalent of a half-Olympic-pool of treated drinking water poured into wall cavities, slab voids, or trench backfill. Multiply this by the number of undetected leaks across a portfolio of buildings or a distribution network, and the cumulative loss becomes substantial. Leak detection is among the most cost-effective sustainability levers available to any BC water user.

AnyLeak’s services align directly with British Columbia’s water-stewardship priorities under the Water Sustainability Act, with municipal water-conservation programs operated by major BC utilities, with climate-adaptation planning under federal and provincial infrastructure programs, and with corporate ESG commitments that many BC organizations have adopted. For property owners and operators reporting on water performance to investors, regulators, or community stakeholders, AnyLeak’s reports provide the concrete evidence that conservation efforts are working.

Beyond water itself, leak detection conserves the energy used to treat and pump water, the chemicals used in treatment, the embodied carbon in the pipe and pump infrastructure that wears prematurely from leak-related stresses, and the construction waste avoided through smaller repair scope. The environmental ROI of a single thorough leak detection investigation typically exceeds many higher-profile sustainability initiatives.

Frequently Asked Questions About Concrete Slab Moisture Detection Metro Vancouver

Will you damage my finishes during the investigation?

No. AnyLeak’s methodology is built around non-invasive inspection. We only recommend an opening once the leak has been pinpointed, and the opening is then as small as possible — typically a 15 × 15 cm access cut rather than full demolition. For BC clients concerned about credentials and accountability, AnyLeak maintains comprehensive general liability insurance, professional liability coverage, automobile liability on all field vehicles, WorkSafeBC clearance in good standing, and bonding capacity through our surety. Verification documents are available on request. We are procurement-ready for residential, strata, commercial, industrial, government, and infrastructure engagements.

How can you find a leak without cutting into the wall?

Modern leak detection uses acoustic correlators that hear leak sound through walls and floors, thermal cameras that detect temperature differentials behind finished surfaces, tracer gas that escapes only at the leak point, and ground penetrating radar that images subsurface conditions. AnyLeak combines these methods to pinpoint the leak before any cutting is recommended. Most property owners considering Concrete slab moisture detection Metro Vancouver for the first time appreciate knowing that AnyLeak has been delivering this kind of engagement across British Columbia since 1999. Our 25-year track record means our technicians have seen the situation you are describing many times before, and our diagnostic methodology has been refined through thousands of comparable investigations. We bring this institutional experience to every engagement, large or small.

Will I need to be home for the entire investigation?

For most residential investigations, the property owner needs to provide initial access and be available for questions and findings discussion. For strata, commercial, and industrial sites, AnyLeak works directly with property managers or facility staff. If your situation evolves between engagement and on-site visit — symptoms change, additional damage appears, urgency shifts — call our line at (604) 269-5325 and let our project coordinator know. We adapt scope, scheduling, and crew composition as the situation requires, with any pricing implications communicated transparently before changes proceed.

How long does a hidden leak investigation take?

Most residential and strata-unit investigations are completed in 1–3 hours. Larger commercial and industrial investigations typically take a half-day to a full day. AnyLeak provides a time estimate during the initial scheduling call. For BC clients concerned about credentials and accountability, AnyLeak maintains comprehensive general liability insurance, professional liability coverage, automobile liability on all field vehicles, WorkSafeBC clearance in good standing, and bonding capacity through our surety. Verification documents are available on request. We are procurement-ready for residential, strata, commercial, industrial, government, and infrastructure engagements.

Can you find leaks in underground service lines?

Yes. Buried service laterals are one of the most common leak sources we investigate. We use acoustic correlation, ground microphones, hydrophones, and GPR to pinpoint underground leaks without exploratory excavation. Our equipment library is one of the most comprehensive in British Columbia and is upgraded continuously as new generations of diagnostic technology become available. This continuous investment is part of why AnyLeak consistently delivers diagnostic accuracy that less-equipped competitors cannot match. Every truck carries the full kit so no return trip to the shop is required mid-engagement.

Can you detect leaks under poured concrete slabs?

Yes. Slab leak detection is one of AnyLeak’s specialties. We use acoustic correlation, thermal imaging, and tracer gas to locate slab-embedded leaks without breaking concrete blindly. If your situation evolves between engagement and on-site visit — symptoms change, additional damage appears, urgency shifts — call our line at (604) 269-5325 and let our project coordinator know. We adapt scope, scheduling, and crew composition as the situation requires, with any pricing implications communicated transparently before changes proceed.

Do you document the investigation for my insurance claim?

Yes. AnyLeak’s reports include pinpoint leak location, photographic and thermographic evidence, instrument readings, leak duration estimate, and recommended repair scope — all formatted to support insurance adjuster review. The economics of professional leak detection almost always favour the investigation when measured against the cost of undetected damage. A typical hidden leak operating at residential pressures wastes thousands of litres per day, gradually saturates surrounding building materials, and accelerates the failure of nearby plumbing infrastructure. By catching the leak early through Concrete slab moisture detection Metro Vancouver, property owners typically avoid restoration costs that exceed the investigation fee by 10× or more.

How accurate is non-invasive leak detection?

On metallic pipes with good acoustic contact, AnyLeak typically pinpoints leaks within 15 centimetres. On plastic and asbestos-cement pipes, accuracy is typically within 1–2 metres. We verify every suspected leak with a secondary detection method before reporting. Our equipment library is one of the most comprehensive in British Columbia and is upgraded continuously as new generations of diagnostic technology become available. This continuous investment is part of why AnyLeak consistently delivers diagnostic accuracy that less-equipped competitors cannot match. Every truck carries the full kit so no return trip to the shop is required mid-engagement.

How do you handle building envelope leaks vs. plumbing leaks?

Many leaks presenting as plumbing failures are actually envelope leaks — roof, flashing, window, or stucco defects. AnyLeak’s investigations include exterior visual inspection, drone survey where appropriate, thermal imaging from both sides, and controlled water penetration testing to differentiate envelope from plumbing causes. If your situation evolves between engagement and on-site visit — symptoms change, additional damage appears, urgency shifts — call our line at (604) 269-5325 and let our project coordinator know. We adapt scope, scheduling, and crew composition as the situation requires, with any pricing implications communicated transparently before changes proceed.

My ceiling is wet — does that mean the leak is directly above it?

Not usually. Water travels along framing members and drops vertically when it encounters obstacles, so the visible wet spot is rarely directly below the actual leak. AnyLeak traces the leak backwards from the symptom to the source. Reports are central to the value we deliver. Beyond identifying the leak, AnyLeak’s written deliverable includes photo evidence, thermal imagery, equipment calibration data, pinpoint leak location with building-drawing markup where applicable, recommended remediation scope, and follow-up recommendations. This documentation typically satisfies insurance adjusters, strata councils, government auditors, capital planners, and engineering consultants without further explanation.
