Plumbing Leak Diagnosis Guide

Scope of Works

• Initial survey – interview the homeowner, review water‑meter data and visible damp patches.

• Isolate & pressure‑test individual circuits (hot, cold, CH) to confirm a hidden leak.

• Non‑destructive tracing with acoustic listening, thermal imaging, tracer gas or dye as appropriate.

• Localise the leak to the smallest possible area and mark cutting points.

• Expose pipework (small access holes in plasterboard/floorboards) and confirm leak visually.

• Temporary or permanent repair to pipe, joint or valve; pressure‑test to prove success.

• Issue written report with photos for insurance ‘trace & access’ claims and advise on reinstatement.
  

Typical Cost (inc. VAT)

Time on Site

Expect 1 – 4 hours.  Extra time is needed if pipe runs are buried in concrete, multiple circuits leak, or significant furniture/floor coverings must be lifted.

Questions to Ask Your Trade

1. Are you trace‑and‑access insured and will you supply a report for my insurer?

2. Which non‑destructive methods (acoustic, thermal, tracer gas) do you carry on the van?

3. If the leak is located, will you repair on the same visit or quote separately?

4. How will you minimise damage when opening floors or walls, and who reinstates afterwards?

5. Do you charge per hour or fixed price for leak detection?

6. What warranty do you offer on both the diagnosis and any repair work?

7. Can you provide evidence of public liability insurance up to at least £2 million?
   

How to Avoid Surprises

• Clear access to all suspected areas (kitchen plinths, airing cupboard, loft hatch).

• Reserve nearby parking for equipment cases and thermal‑imaging kit.

• Photograph existing water damage for insurance before work starts.

• Confirm whether evening/weekend rates apply if the appointment overruns.

• Locate and label the main stop‑cock; test it closes fully before the engineer arrives.
