What kinds of leaks do we help with?
Whether it's a drip, a damp patch, rising damp, or something less obvious — we help identify what's happening and what to do next.
Underfloor Leaks
Leaks beneath solid floors, tiles, or timber boards — located using acoustic and thermal methods, so nothing gets lifted unnecessarily.
Leaks Behind Walls
Hidden pipe failures behind walls, tiling, or plasterboard — mapped through moisture scanning before any opening-up work begins.
Ceiling Leak Sourcing
Water appearing through a ceiling from a flat above or a roof space — traced back to the actual source, not just the nearest damp patch.
Heating System Loss
Unexplained drops in central heating or underfloor heating pressure — diagnosed using pressure tests and tracer gas to locate where it's escaping.
From first message to found leak
You don't need to know what's wrong. Just describe what you're seeing — we'll handle everything else.

How leaks are found
Thermal Imaging
Detecting temperature differentials caused by hidden moisture behind structures.
Acoustic Profiling
Highly sensitive microphones that listen for the sound of water escaping from pipes — often effective through concrete and masonry.
Moisture Mapping
Electronic deep-wall probing to track the spread of dampness to its origin point.
Tracer Gas & Pressure
A safe, harmless gas is introduced into the pipe. It escapes at the leak point and is detected at the surface to pinpoint the exact location.
