What Underfloor Heating Leak Detection Involves
Underfloor heating (UFH) runs warm water through a network of loops buried in screed, concrete or laid beneath a timber floor. Because those pipes are hidden, a leak rarely shows itself in an obvious way. Instead you tend to see the system steadily losing pressure, a boiler or manifold topping up more often than it should, patches of floor that stay stubbornly cold, or damp creeping up at the edges of a room.
Our job is to find exactly where the loop has failed before anything is lifted or opened up. We combine thermal imaging, which maps how heat travels through each circuit, with individual loop pressure testing that isolates a single circuit at a time. By the time we leave, you know which loop is leaking and roughly where along its run, so any repair can be kept to a small, targeted area rather than a whole floor.
This non-destructive approach matters most with underfloor heating, where the alternative is breaking up large stretches of finished flooring on a hunch. We work carefully and quietly in your home, and where it helps a claim we provide a clear, insurance-approved report of our findings.
Signs Your Underfloor Heating May Be Leaking
- Pressure on the system keeps dropping and needs topping up
- Cold spots or whole loops that never warm through
- Unexplained damp patches on the floor or at skirting level
- Higher heating bills with no change in how you use the system
- The boiler or manifold cycling or refilling more than usual
How We Find Underfloor Heating Leaks
Thermal Imaging
A thermal camera lets us see the warm pipework through the floor and map each heating loop without lifting a single tile or board. Escaping water disturbs that heat pattern, so an unexpected warm or cool trail often reveals where a loop has failed.
Loop Pressure Testing
At the manifold we isolate and pressure-test each loop in turn. The circuit that will not hold pressure is the one that is leaking, which narrows the search from a whole floor down to a single run of pipe and confirms the fault beyond doubt.
Tracer Gas
For a stubborn leak in screed or concrete, a safe tracer gas is introduced into the suspect loop. The gas rises to the surface at the exact point of escape, where our detectors pick it up and mark the spot for a small, precise repair.

Underfloor Heating Leak Detection FAQs
Yes. We combine thermal imaging, loop pressure testing and, where needed, tracer gas to locate the leak before anything is opened up. That lets the repair be kept to a small, targeted area instead of disturbing a whole floor.
A steady pressure drop usually points to water escaping somewhere in a loop, a manifold fitting or a connection. Isolating and pressure-testing each circuit shows us which loop is failing, so we can confirm whether a leak is the cause.
Yes. Underfloor heating set in screed or concrete is exactly where our methods come into their own. Thermal imaging and tracer gas let us trace the loop and pinpoint the escape point through solid floors with no guesswork.
Same-week appointments are often available across Devon in most cases. If you are losing pressure or seeing damp, call us on 07897 027775 and we will arrange the soonest convenient slot for your home.
Yes. Where it supports a claim we provide a clear, insurance-approved report setting out our findings and the location of the leak, which your insurer or chosen contractor can use to plan the repair.
