Leak Detection

Narrow It Down Before You Open Anything

The expensive part of a hidden leak is not the pipe repair — it is the demolition and reinstatement around it. Every wall opened in the wrong place is drywall, paint and time that bought you nothing.

So we work from evidence outward: meter behaviour, isolating the system section by section, moisture readings across surfaces, and acoustic listening on pressurised lines. By the time anything gets opened we know where the water is, not where it happens to be showing.

✓Meter and isolation testing — establishes that there is a leak, and roughly where.
✓Moisture mapping — finds the wet zone behind an intact surface.
✓Acoustic listening — pinpoints escaping water on pressurised lines.
✓Non-plumbing causes ruled out — condensation and roof leaks look identical from inside.
✓Written findings — what we found and where, with photos for your insurer.

Warning Signs

The Three Signs Worth Acting On

The meter moves with everything off

This is the closest thing to proof there is. Turn everything off, watch the meter for fifteen minutes. Movement means water is escaping somewhere.

A bill that climbed for no reason

Habits did not change but the bill did. Most often a running toilet or an underground service line — both invisible, both continuous.

A musty smell in one room

Your nose finds damp before your eyes do. A persistent musty smell in one specific area usually means something has been wet for a long time behind a surface.

Most calls turn up something else worth looking at. Here is what else we handle.

Leak Detection Questions

The meter test is the simplest. Turn off every tap and water-using appliance, then look at your water meter. If the dial is still moving, water is going somewhere. Other signs: a bill that has climbed without a change in habits, a warm patch on a floor, a musty smell in one room, paint or plaster bubbling, or mould appearing in a spot with no obvious source.

That is exactly what we are trying to avoid. We work from the evidence — meter behaviour, isolating sections of the system, moisture readings, and listening — to narrow the location down before anything is opened. The goal is one small access point in the right place rather than several in the wrong ones.

Into the ground, into a wall cavity, under a slab, or straight down a drain. A running toilet is the single most common cause of a mystery bill and it makes almost no noise. An underground service line leak between the meter and the house is the other big one, and it can lose a lot of water with nothing visible at the surface.

No, and it matters. Condensation, a roof leak, failed window flashing and rising damp all look similar from inside. Part of the job is establishing whether this is a plumbing problem at all before you spend money on a plumber for something that is actually a roofing issue.

If the leak is significant, shut off the main and only turn it on when you need water. Move anything valuable away from the damp area. Photograph it — your insurer will want to see the progression. Do not start cutting into the wall to look; it rarely lands in the right place and it complicates the claim.
