Leak Detection & Repair

A hidden water leak can cause thousands of pounds of damage before it becomes visible. Escape of water is one of the most common causes of home insurance claims in the UK — and that doesn't include the disruption of drying out and redecoration. Modern leak detection technology means our engineers can locate leaks beneath floors and behind walls without unnecessary destruction.

What is Leak Detection & Repair?

Leak detection and repair covers locating and fixing any water leak in your plumbing system — whether visible or concealed. We use thermal imaging cameras, acoustic detection equipment, and tracer gas to pinpoint leaks in buried or concealed pipework without exploratory damage. Once located, the leak is repaired and the system pressure-tested to confirm the fix.

When Do You Need Leak Detection & Repair?

Unexplained increase in water bill

Damp patches appearing on walls, floors or ceilings

Sound of running water when all taps are off

Water meter spinning when no water is being used

Hot spots on floor (could indicate underfloor heating leak)

Mould or mildew appearing in unusual locations

Boiler pressure constantly dropping

Frequently Asked Questions

How do I know if I have a hidden leak?

The most reliable test is to turn off all water-using appliances and check your water meter. If the dial is still moving, you have an active leak. Other signs include unexplained damp, a musty smell, or your boiler pressure dropping regularly.

Will you need to break up my floor or walls?

Modern detection equipment means we can locate most leaks without breaking anything. Once located, access is minimal — often a single tile or small section of flooring. We aim to leave the smallest possible access point.

Will my insurance cover the leak repair?

Most buildings insurance covers damage caused by escape of water. The repair itself may or may not be covered depending on your policy. We provide a detailed report and invoice to support any insurance claim.

How long does leak detection take?

Detection typically takes 1-3 hours depending on the size of the property and complexity of the leak. Repair time varies — a simple pipe joint repair takes under an hour, while a burst underground main may take a full day.
