PLUMBING · LEAK DETECTION

Find the leak before it finds the drywall.

Water bill spike with no explanation? Mystery damp spot in the ceiling? A warm patch on the slab where there shouldn't be one? We locate hidden leaks — behind walls, under floors, inside concrete slabs — using thermal imaging, acoustic detection, and moisture metering. No opening up walls until we know exactly where the leak is.

WHAT WE FIND

Every kind of hidden leak.

If water is going somewhere it shouldn't — pressurized supply, drain line, recirc loop, slab — we'll locate it without opening up half your house.

Behind-wall pipe leaks

Hot or cold supply lines weeping inside finished walls — staining the drywall, feeding mold, and never quite drying out.

Under-floor + slab leaks

Pipes running below subfloor or embedded in concrete slabs. Symptoms include warm spots, buckled flooring, and an unexplained water bill.

Outdoor service line leaks

The main line from the city shutoff to your home. Soggy patches in the lawn, low pressure, or a meter that ticks with everything off.

Hot water recirculation leaks

Recirc loops fail quietly — the system keeps making hot water and you keep paying for it. We find the failed leg and rebuild the loop.

Pinhole leaks in copper

Aggressive water or aged copper produces pinholes that drip for months before you notice. We find them and repipe the affected sections in copper or PEX.

Drain & waste pipe leaks (in walls)

Cracked ABS, failed solvent joints, or corroded cast iron behind a wall. Smells musty, stains the ceiling below, but no obvious source.

OUR APPROACH

How we find it without tearing walls open.

The cheapest leak repair is the one where we open one small access panel — not the one where we guess wrong three times. Our techs carry the diagnostic gear to pinpoint the source before the first cut.

01

Thermal imaging

A calibrated thermal camera finds the temperature gradient where hot water is escaping into a wall or floor cavity. Hot supply leaks light up immediately; cold leaks show up as evaporative cold spots within minutes.

02

Acoustic leak detection

Pressurized water escaping through a small breach makes a very specific sound — somewhere between a hiss and a rush. Ground microphones and contact sensors let us listen for that signature through tile, drywall, or slab and walk it back to the source.

03

Moisture metering

Pin and pinless moisture meters tell us exactly where the damp area starts and stops behind the surface. That's how we mark a 20cm access panel instead of opening a whole wall.

04

Pressure isolation testing

By isolating sections of your supply system and pressure-testing each leg, we can narrow the leak down to a specific run — hot side, cold side, recirc, or service line — before any imaging even starts.

WARNING SIGNS

Signs you have a hidden leak.

Hidden leaks rarely announce themselves. If any of these sound familiar, get it checked before the damage compounds.

01 / BILLING

Water bill jumped without explanation

Same household, same habits, but consumption is suddenly up 20–50%. The water is going somewhere — usually a slab or service line leak.

02 / SLAB

Warm spot on the floor

An unexplained warm patch on tile or concrete almost always means a hot-water slab leak. The longer it runs, the worse the damage to flooring above and structure below.

03 / VISIBLE

Damp spots, peeling paint, musty smell

A stain that comes back after you paint over it. A persistent musty smell in one room. Bubbling drywall. All early signs of water moving where it shouldn't.

04 / METER TEST

Water meter ticks when nothing is running

Turn off every fixture and look at the leak indicator on your meter. If it's spinning, you've got a leak somewhere on the pressurized side. Call us — this one's diagnostic gold.
