Leak Detection › Slab Leaks

Slab leak
repair.

Found under the concrete, fixed before the foundation pays for it.

Under the concrete

A leak under the slab
is a foundation problem
waiting to happen.

A slab leak is a water line failing underneath the concrete your house sits on. It runs day and night, it does not show up as a puddle, and the first thing most people notice is the bill. Left alone, the water works on the soil under the foundation, and what started as a plumbing repair turns into a foundation repair.

Encore finds it first and opens the floor once, in the right place. Acoustic listening, line tracing and pressure testing tell us where the water actually is before a single tile comes up. That is the whole difference between a tidy repair and a house with holes in it.

Know the signs

How a slab leak
tells on itself.

Most people call after the bill arrives. These are the tells that come first.

01

A warm spot on the floor

A hot-water line under the slab heats the concrete above it. If one patch of floor is warm underfoot and the rest is not, that is a hot line leaking.

02

Water running with everything off

Shut every tap and appliance and stand still. A faint hiss or trickle means water is still moving somewhere it should not be.

03

The bill jumped for no reason

Same household, same habits, a much bigger number. A slab leak runs twenty-four hours a day and it never shows up as a puddle.

04

Cracks, or doors that stopped closing

Water under a foundation moves it. New cracks in brick or drywall and doors that suddenly stick are the slab telling you something changed.

05

Damp carpet or a musty smell

Moisture wicking up through flooring, or that closed-up smell in a room nobody uses. It is coming from underneath.

06

The meter keeps moving

Find the meter, note the dial, use no water for an hour. If it moved, you have a leak between the meter and the house.

Any two of these together is worth a call. A slab leak does not get better on its own, and the foundation is the expensive part.

Real Encore job

Start to sealed.

Photographs from our own slab work — not stock, not somebody else’s job.

Floor marked and prepared before opening the slab
01Located, then marked

The leak is pinpointed and marked before anything is cut. One cut, in the right place.

Slab opened with a clean square access cut for the repair
02Opened clean

A square access cut down to the line. Contained, tidy, and no bigger than the repair needs.

Slab repair sealed and fresh concrete poured back
03Sealed and poured back

The line repaired or re-routed, then the concrete closed up and finished.

The other route

Sometimes we go
under it instead.

Not every slab leak should be reached through the floor. Where it makes more sense we tunnel in from outside, and the finished floors inside never get touched.
