Finding Where It Is Coming From
Most household leaks are found by isolating the system section by section and watching what the meter and the pressure do. It is methodical rather than clever, and it is right most of the time.
- Stopcock and meter check first
- Sections isolated one at a time
- Pressure test to prove it
- You are told what I find, not just what it costs
Under Floors and Behind Walls
When it is concealed, the job is narrowing it down before anything is lifted. Boards up in the right place beats boards up in six wrong ones.
- Narrowed down before lifting
- Access made good afterwards
- Damp traced to its source, not its puddle
- Honest about what has to come up
When It Needs Specialist Kit
A slab leak, a long buried run, or a leak that will not show itself needs thermal imaging, acoustic tracing or tracer gas. That gets brought in, or passed to a specialist — and I tell you which before you are charged for guessing.
- Brought in when the job needs it
- Passed on when a specialist is the right answer
- Cost agreed before anything extra arrives
- No charge for telling you it is not my job

Common questions about our leak detection services in Andover, Marlborough & Hungerford.
How do you detect leaks without damaging my property?
Methodically. The meter and the stopcock tell you whether water is still moving, then the system is isolated a section at a time until the loss stops in one of them. That narrows a whole house down to a run of pipe, usually without lifting anything. Where a leak will not show itself that way, thermal imaging, acoustic tracing or tracer gas is brought in, or a specialist is — and you are told which before you pay for guessing.
Will you have to pull my floor up?
Usually not to find it. The point of isolating and pressure testing first is to turn the whole house into one run of pipe before anything comes up, so boards go up in the right place rather than in six wrong ones. If access is needed I will say so before starting, and it gets made good afterwards.
Can you detect leaks in underfloor heating systems?
Yes. A wet underfloor circuit can be isolated loop by loop at the manifold and pressure tested, which finds the failing loop without disturbing the floor. What happens next depends on where in that loop it is, and I will be straight with you about whether it is a repair or a re-run.
Do you provide emergency leak detection services?
Yes. Urgent leaks are prioritised and usually attended the same day, subject to availability. Emergency services start from £285 + VAT.
What happens after you find the leak?
Once we locate the leak, we provide detailed reports with precise location mapping and can arrange immediate repairs to minimize water damage and restore your system.

Professional Detection Equipment
The first tools on any leak are the water meter, the stopcock and a pressure gauge, and between them they find most household leaks without a camera in sight. Thermal imaging, acoustic tracing and tracer gas are for the ones that will not show themselves; those are brought in for the job, or handed to a specialist, and you are told which before any of it is charged for.
