Leak Detection Plumber

What Leak Detection Does, and What It Does Not

This service assesses a suspected leak when the source or route is unresolved. Findings may support no immediate plumbing work, further investigation or routing to a separate repair pathway. Slab Leak Detection card begins when evidence or building configuration makes an under-slab domestic supply line a material hypothesis. Confirmed interior supply-pipe, slab, buried branch-line, main-water-service and broader repiping work remain separate decisions.

How a Leak Assessment Is Built

No fixed test sequence fits every property. The useful sequence depends on the symptom, piping, building construction, safely accessible shutoffs, shared systems and the areas that can be inspected.

Review the symptom and water use. Note when the issue began, whether it is constant or intermittent, which fixtures or equipment were operating and what has changed. A safely accessible meter or usage record may add evidence, but movement does not identify the source, route or responsibility by itself.

Inspect accessible evidence. Staining, damp materials, visible piping, fixture behaviour, previous openings and renovation history can help define the likely system and affected area. Water may travel before it becomes visible, so the wettest or most obvious location is not automatically the source.

Select tests for the property. Isolation, pressure or flow information, moisture observations and other suitable methods may help narrow the possibilities. Method choice depends on the identified system, pipe material, operating state, access and safety conditions. No instrument establishes the complete answer on its own.

Separate findings from inference. The assessment should state which observations and test results are confirmed, what remains inferred, which areas were inaccessible and what uncertainty remains. Confidence can change when concealed construction, shared piping or limited isolation prevents a complete test.

Route the next step. The result may support monitoring, further investigation or a separate repair assessment. Detection evidence can inform a decision, but it does not choose the repair, reroute, repipe or replacement by itself.

The assessment should give the homeowner a clear account of the evidence, limits and appropriate next pathway without overstating precision, cause or the condition of piping that was not assessed.

Property Factors That Change the Assessment

Original construction era can help frame questions, but it does not establish which piping remains after renovations or earlier repairs. More useful evidence includes visible pipe markings, repair and renovation history, dwelling form, shared risers or shutoffs, finished areas, accessible service routes and the locations where symptoms occur. Colour alone does not identify Poly B or determine pipe condition. Confirmed or suspected Poly B concerns route to the dedicated Poly B pathway.

Start With Safety

If water is active, check for gas and electrical hazards before approaching the area or operating a valve. Stay out of wet electrical areas and away from sagging ceilings or unstable finishes. Use only a safely accessible private shutoff, never force a questionable valve and never operate a municipal curb stop. Move property or take photographs only after hazards and active flow are controlled. If the route, meter, valve or affected area is unsafe or restricted, stay clear and call from a safe location.

Why Prompt Assessment Matters

A suspected leak can continue using water or affecting finishes while the source remains unresolved. The consequence depends on the flow, location, materials, ventilation, access and how quickly the water can be controlled. Prompt assessment helps separate an active plumbing concern from another moisture or usage issue and identifies whether another trade should be involved.

Insurance coverage and documentation requirements vary by policy and loss. Contact the insurer or broker for the applicable requirements. Record dates or photographs only when that can be done safely after hazards and active flow are controlled.

What Affects the Cost

The assessment scope depends on the symptom, systems involved, safe access, number of possible sources, available isolation, shared-building constraints and whether concealed areas or separate trades are involved. Pricing and deliverables should follow the confirmed scope rather than a universal package or guaranteed result.

If You Live in a Strata, Duplex, or Rental Suite

Detached-home assumptions do not automatically apply to shared buildings. A suspected unit-side line, shared riser, common shutoff or building-side pipe can involve different access and authorization. Confirm the building type, users served, shutoff control and property-management procedure before testing or opening shared areas. The assessment should not promise responsibility or authorization outcomes.

What to Have Ready Before We Arrive

• Any safely observed meter or usage change. Do not force a valve, operate a municipal curb stop or enter a wet or restricted meter area.
• When the symptom began, whether it is constant or intermittent and what has changed.
• The building’s approximate construction and renovation history, plus previous leak or repair locations if known.
• Whether the property is detached, shared, rental or strata-managed, and who controls access or shared shutoffs.
• Photographs that can be taken from a dry, safe location after hazards and active flow are controlled.
