Leak detection service
Underfloor heating losing pressure or leaving cold patches? We trace UFH leaks under tile, screed and concrete across Cornwall, without lifting the whole floor.
Underfloor heating runs in continuous loops buried in screed or under tile and concrete, so when one springs a leak there is nothing to see. You just get a heating system that keeps losing pressure, cold patches where a loop has failed, or rising damp in the floor. Lifting an entire floor to find it is the last thing you want.
We trace underfloor heating leaks across Cornwall using thermal imaging and tracer gas, following the loops and pinpointing the exact failure point. That means the screed or tiling only needs opening at one spot, which protects your floor and keeps repair costs down. For wider heating problems we also offer central heating leak detection, and our thermal imaging and insurance-backed trace and access services support any claim.
Signs of a UFH leak: the system pressure keeps dropping, a cold patch where a zone should be warm, damp or discolouration in the floor, or the boiler and manifold needing frequent topping up. Our Water Leak Guide explains what to check first.
The instinct with an underfloor heating leak is to start lifting floor to find it. That is slow, expensive and often misses the spot, and the leak keeps costing you in the meantime.
Left unresolved, an underfloor heating leak can:
✓keep dropping the system pressure, so it never heats properly✓leave cold patches where a loop has failed✓cause damp in the screed and the floor finish above✓turn into major floor removal if the leak is chased blind
We pinpoint the failed loop before anything comes up, so the repair is targeted and as little floor as possible is disturbed.
Our method
Thermal imaging to map the heated loops and reveal the cold/wet area at a leak
Tracer gas introduced into the circuit and detected where it escapes through the floor
Pressure testing to confirm the loss and isolate the affected loop
Moisture mapping to narrow the exact spot before any access
Local to Cornwall, not a franchise from up country
We protect your floor with one targeted access point, not the whole room
Insurance-approved trace & access reports

Yes. Thermal imaging and tracer gas let us follow the heating loops and pinpoint the leak, so the screed or tiling only needs opening at the exact failure point rather than across the room.
The usual cause is a small leak somewhere in a loop or at a manifold connection, though a faulty expansion vessel or valve can also be responsible. If you are topping up repeatedly with no visible water, a hidden leak in the floor is likely.
Yes. Tracer gas and thermal imaging work through tile, screed and concrete, so we can locate leaks in solid floors without breaking them up to look.
