What is actually going on
Warm or damp patches on the floor, unexplained pressure loss, or the sound of running water with all taps off.
The realistic causes, in order
A failed joint on buried heating pipework, especially where pipes were laid in screed Corrosion of copper in contact with screed or concrete without sleeving A nail or fixing driven through a pipe during flooring work
What we test on site
Pressure testing to confirm which circuit is losing water Thermal tracing across the floor surface to narrow the location before lifting anything Whether an above-floor re-route is less disruptive than excavating
Get a leak under the floor diagnosed properly
Once located, we discuss repair versus a re-route so you can choose on disruption as well as cost.
Questions we get asked
Where does a leak under the floor usually start in the pipework?
A failed joint on buried heating pipework, especially where pipes were laid in screed
What normally puts a leak under the floor right?
Once located, we discuss repair versus a re-route so you can choose on disruption as well as cost.
Is it safe to keep using the system with a leak under the floor?
Locating before lifting matters. Randomly lifting floors is expensive and rarely finds the leak first time.
