Water Leak Investigations — London & Surrey

Water Leak Investigations for Complex Leaks and Insurance Claims

When a leak keeps coming back, the damp doesn’t make sense, or an insurer wants proper evidence — that’s an investigation, not a quick trace. We document the cause with methods, readings and photographs, and give you a report that stands up. Fully insured and qualified damp, mould and leak specialists.

When you need an investigation rather than basic detection

Repeat leaks after previous “fixes”
Unexplained damp with no obvious source
An insurance claim or dispute needing documented evidence
Damage from an escape of water where the cause must be distinguished from pre-existing issues
Trace-and-access evidence for a policy claim

For straightforward leak-finding, see leak detection. This page is the deeper service behind it.

Active escape of water found beneath a kitchen sink during a DML investigation.

What the investigation includes

Symptoms and damage — mapped and photographed.
Meter and pressure testing — proving whether a system or supply is losing water, and how fast.
Moisture mapping — calibrated readings separating active leaks from residual damp and condensation.
Thermal evidence — temperature anomalies consistent with escaping water.
Acoustic readings — leak noise located on pressurised pipework.
Tracer-gas results — where suitable, pinpointing escape through floors and screeds.
Suspected leak position — stated clearly, with the reasoning.
Minimum access required — the smallest sensible opening, and why.

Insurance-ready leak evidence we can provide

Depending on the policy and claim, insurers or loss adjusters may ask for:

Calibrated moisture reading recorded as claim evidence on a water-damaged wall.

Cause and source notes
Location of the suspected leak
Methods used and why
Readings, thermal images and photographs
Access recommendations (minimum necessary)
Repair recommendations
Reinstatement notes where relevant
Limitations — what the evidence does and doesn’t establish

Reports are prepared to support your claim. Acceptance of any claim is always the insurer’s decision.

What we can and cannot confirm

We tell you what the evidence supports — and where it stops. If a source can’t be confirmed without access, the report says so and recommends the minimum access to confirm it.

Next steps after the report

Report delivered with findings and recommendations.
You (or your insurer) decide on the works — repairs and reinstatement are quoted based on the job.
