Damp patches, a rising water bill, a boiler losing pressure or the sound of running water? We pinpoint hidden leaks without ripping up your home, using thermal imaging and acoustic tracing, then fix them.
Using thermal imaging and acoustic tracing, we pinpoint the exact spot before we lift a single tile, so there's no digging and guessing. Once we've found it, we access it and fix it, and provide a report for your insurer if you need one.
Hidden leaks rarely fix themselves and only get more expensive. Here's what to look for, and where they usually hide.
Staining, bubbling paint, a musty smell or mould on walls, ceilings or floors with no obvious source.
A bill that's crept up with no change in use is one of the clearest signs of water escaping somewhere.
If your boiler needs topping up regularly, there's often a small leak somewhere in the heating pipework.
The trickle or hiss of water when nothing's turned on usually means a pipe is leaking out of sight.
Leaks in pipework buried under floors or in the screed, common with underfloor heating, and hard to find without the right kit.
Concealed pipes running through walls can leak for weeks before the damp shows, we trace them without tearing the wall apart.
A pinhole leak on a heating pipe drops your boiler pressure and wastes water. We find the exact spot and repair it.
Failed seals, waste pipes and shower trays are a frequent culprit, especially when it's the flat below noticing it.
