Boiler keeps losing pressure? There may be a hidden leak.
If you are topping up your boiler pressure again and again but can’t see any water, there is often a small leak somewhere in the central heating pipework. It is frequently under floors, in a screed, or behind a wall where it is impossible to spot. Left alone it can damage flooring and structure and leave you without heating.
We trace central heating leaks across Cornwall without lifting every floorboard. Using tracer gas and thermal imaging we follow the pipe run and pinpoint the exact leak, so any repair is targeted and the disruption is kept to a minimum. Our water leak guide explains how these hidden leaks develop.
Signs of a central heating leak: pressure that keeps dropping on the boiler gauge, having to re-pressurise the system regularly, warm or damp patches on the floor, cold spots on radiators, or the sound of the boiler firing up more often than it should.

What happens if you keep topping up the pressure
Topping up the boiler is a quick fix, not a cure. If the pressure keeps dropping, water is escaping somewhere, and that water has to go into your floors and walls.
Left unresolved, a central heating leak can:
- force you to refill the system again and again
- let air and fresh water in, causing the corrosion and sludge that wear out a boiler
- rot floorboards or stain the ceilings below
- become a much bigger pipe failure if the weak point finally gives way
We find the leaking section without lifting your whole floor, so it can be repaired before it does lasting damage.
How we find central heating leaks
Tracer gas goes into the system and we detect it where it escapes, which pinpoints the leak under floors or screed
Thermal imaging maps the warm pipe runs and the cold, wet area around a leak
Pressure testing confirms the system is losing water and helps isolate the affected circuit
Acoustic and moisture mapping narrows down the exact spot before any access

Central heating leak FAQs
The most common causes are a small leak somewhere in the pipework or radiators, or a faulty expansion vessel or pressure relief valve. If you are repeatedly topping up the pressure and can’t see any water, a hidden leak under a floor or in a wall is likely, which is exactly what our detection finds.
Yes. Tracer gas and thermal imaging let us follow the pipe run and pinpoint the leak, so any floorboards or screed only need to be opened at the exact spot rather than across the whole room.
Our specialism is locating the leak precisely and providing the report. We can advise on the repair and work alongside your plumber or heating engineer so the fix is quick and targeted once we’ve pinpointed it.
Many home insurance policies include trace & access cover, which pays towards finding and accessing the leak. We provide an insurance-approved report to support your claim, subject to your policy terms.
