Leak detection in Macclesfield
In short
Leak detection is finding water that is escaping somewhere you cannot see — under a floor, inside a wall, above a ceiling or below a solid slab. It is done by isolating sections of pipework and watching the meter, then narrowing down with acoustic, thermal or tracer methods, so that the smallest possible amount of floor or plaster has to come up.

Signs you need this
- Water bills up with no change in how much you use
- The meter still turning with every tap and appliance off
- Damp patches, musty smells or bubbling paint
- An unexplained warm area on a floor
- Boiler pressure dropping repeatedly with no visible leak
- The sound of running water when nothing is running
A hidden leak announces itself indirectly. A water bill that has climbed for no reason. A warm patch on a floor. A boiler that keeps losing pressure. Damp in a corner that never dries. A meter dial that creeps round with every tap in the house closed. None of those tell you where the water is going, and guessing is expensive — the cost of a hidden leak is rarely the pipe, it is the floor that came up looking for it.
The diagnosis is methodical. First, confirm there is a leak at all: close the internal stopcock, watch the meter, and see whether it still moves. Then isolate — the heating circuit, the hot side, the cold side, the outside tap, the supply pipe between the boundary and the house — closing one branch at a time until the meter stops. That process alone will often halve the search area before any specialist kit comes out of the van.
From there the tools vary with the situation. Acoustic listening equipment picks up the hiss of pressurised water escaping, which works well on mains-pressure pipework under solid floors. Thermal imaging shows the temperature difference where hot water is tracking through a structure, which is ideal for heating pipes in screed. Tracer gas — a harmless hydrogen and nitrogen mix pushed into a drained pipe and detected where it surfaces — finds the leaks the other two methods cannot.
Access is the part worth thinking about before the work starts. Trace and access means opening up: lifting a few boards, cutting a neat section of plasterboard, taking up a strip of tiling. A good plumber makes the smallest hole that gets the job done and tells you in advance where it will be. Most home insurance policies cover trace and access costs even when they exclude the repair itself, so it is always worth checking your policy before you commit.
Local construction affects how these jobs run. Central Macclesfield has a great deal of pre-1919 housing — over half the stock in the town centre by council tax records — which usually means suspended timber floors, accessible voids and pipework that has been added to by several generations of plumber. Post-war estates like Weston, where four out of five homes went up between 1945 and 1982, more often mean solid floors and pipework in screed, where the detection work matters far more because the access is destructive.
Once found, the repair is usually the quick part. What you are really paying for is not opening up six places to find one leak.
What the job covers
- Meter test to confirm a leak exists and gauge its size
- Systematic isolation to narrow down the affected circuit
- Acoustic, thermal or tracer gas detection as the situation needs
- Minimal, agreed access — the smallest opening that reaches the pipe
- Repair of the located leak and a pressure test afterwards
- A written report suitable for a trace and access insurance claim
What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your plumber has to honour it. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
How do I know if I have a leak at all?
Turn everything off, note the meter reading, and leave it for an hour without using any water. If it has moved, water is going somewhere. On a heating system, the same logic applies to the boiler pressure gauge: if it drops steadily over days, the system is losing water.
Will my insurance pay for finding it?
Many home insurance policies include trace and access cover — the cost of locating the leak and opening up to reach it — even where the pipe repair itself is excluded. Check the policy wording before work starts, and ask your plumber for a written report.
