Leak detection
Leak detection
Non-destructive leak detection to trace hidden plumbing and water leaks behind walls and under floors before damp spreads.
Why diagnosis matters
Treat the cause, then repair the damage
A hidden leak can mimic rising or penetrating damp and cause lasting damage before it is found. We use non-destructive detection methods to trace the source of hidden water leaks, so the repair is targeted and disruption is kept to a minimum.

Common questions
About leak detection
Can you find a leak without ripping everything out?+
Yes. Non-destructive methods let us trace most hidden leaks with minimal opening up, so we only expose the specific area that needs repair.
Is my damp actually a leak?+
Sometimes. Leaks can imitate rising or penetrating damp. Detection helps confirm whether a plumbing leak is the real source before any damp treatment is specified.
Do you fix the leak once you find it?+
Yes. We carry out plumbing leak repairs in-house once the source is located, and refer specialist or mains-supply work where it falls outside our scope.
Is the specialist survey really free?+
Yes — completely. We offer every homeowner and property manager across Dorset, Hampshire and Wiltshire a complimentary specialist survey at no charge. This includes an on-site inspection, written findings, a clear scope of any recommended work, and an honest referral if the problem falls outside what we do. You pay nothing for the survey. You only pay if you commission the remedial work, and you are under no obligation to do so. The reason we do this is straightforward: we believe in diagnosing the problem before recommending a treatment. A proper inspection takes time, and we'd rather invest that time up front than quote a solution before we've understood the cause.
Not sure if this is your problem?
That's exactly what the survey is for. Book your complimentary specialist survey and one of our experienced team will identify the cause on-site, consider the alternatives, and give you written findings — at no charge and with no obligation.
