The right equipment.
A targeted investigation.

We use specialist diagnostic methods to narrow down the source of hidden leaks and reduce unnecessary disruption.

Acoustic Detection

Specialist listening equipment helps identify the sound and location of escaping water through pipework and surrounding materials.

Tracer Gas

Tracer-gas testing can help locate difficult leaks where the source cannot be identified by visual inspection alone.

Thermal Imaging

Thermal cameras help identify temperature differences and potential problem areas behind floors, walls and ceilings.

First steps for a water leak

Water leaking right now?

Put safety first. Keep clear of water-affected electrics before trying to stop a leak.

  1. Limit the water

    If you know where your internal stop tap is and can reach it safely, close it gently. Never force a stuck valve or enter standing water to reach it.

  2. Keep clear of electrics

    Do not use water-affected sockets or appliances, touch exposed wiring, or touch a wet or damaged fuse box. A registered electrician should check affected electrics before they are used again.

  3. Call with the key details

    For urgent water leaks, call 020 3488 1229. Tell us the job postcode, where water is escaping and whether the supply is off. Attendance depends on engineer availability and location; call-out fees apply.
