Not sure where the water is coming from?

These are common reasons to arrange specialist leak detection.

Boiler pressure keeps dropping

Pressure loss with no obvious puddle can point to concealed pipework.

Damp with no visible source

Staining or damaged finishes can appear away from the leak itself.

Flooring is lifting or warm

Water beneath a floor needs careful investigation before opening up.

Unexpected water use or sound

Running-water sounds or unusual usage can justify a closer survey.

Finding the leak and agreeing the repair

An engineer investigates the likely source, using tests suited to your property. The aim is to narrow down the leak before opening floors, walls or ground.

Engineers usually repair the leaks they find. The fault, access and work required determine what can be done, and some repairs need a separate visit. Agree the repair and any additional costs with the contractor.

Tell us before booking if you need a leak-detection report, so its scope and cost can be agreed.

Questions before you book

How much will the investigation cost?

The quote depends on the property and investigation needed. Agree the scope, price and report requirements before booking, and ask about separate charges for access, repairs and making good.

Will floors or walls need to be opened?

Tests aim to narrow the search before anything is opened. Access may still be needed depending on the fault and property.

Will the engineer repair the leak on the same visit?

Engineers usually repair leaks, but same-visit completion cannot be promised. Agree the work and any additional cost with the contractor.

Do I need to choose a detection method?

No. Describe the symptoms and property so suitable tests can be discussed. The engineer chooses methods appropriate to the investigation.
