In Agoura Hills

The slab leak we fixed under an Agoura Hills bedroom closet in November 2023 is typical. It was a pinhole in a one-inch copper line under a seventies house. The locator marked the leak and the post-tensioned cables, and we opened the floor at one spot and replaced the section. Morrison Ranch and Liberty Canyon houses are the right age for it.

Neighborhoods: Old Agoura, Morrison Ranch, Liberty Canyon, Lake Lindero, Chesebro, Fountainwood.

Slab leaks in the tracts

Morrison Ranch and Liberty Canyon are the right age for it. We find the leak, then fix the spot or reroute the line.

The job

How it goes

A slab leak is a water line leaking under or inside the foundation. Soil, concrete, high pressure and hard water all wear the copper thin, and hot lines go first.

We isolate the line with the meter and gauges, and the leak-locating specialist we bring in marks the spot within a foot or so, plus any post-tensioned cables. A spot repair opens the floor there and replaces the bad section. A reroute abandons the line under the slab and runs a new one through the attic, leaving nothing in the concrete.

One leak on a sound line is a spot repair. A second leak within a year or two means the pipe is done, and a reroute beats opening the floor again. We'll tell you which you've got.

Call if

What you notice,
and what it usually is

01

A warm patch on the floor

A hot line leaking under the slab.

02

The meter turns with everything off

A pressurized leak. If nothing's visible, it's usually the slab.

03

Damp carpet or lifting floors with no fixture nearby

Water coming up through the slab.

04

The water heater runs all the time

Hot water's leaking out, so the tank never catches up.

05

A second leak a few months after the first

The line is failing. Time to talk about a reroute.

    A slab leak under a bedroom closet

    It started as a slow shower drain. We traced the copper under the slab and found a leak, and the leak-locating specialist we bring in marked it and the post-tensioned cables. We saw-cut and jackhammered the closet floor, found a pinhole in a one-inch copper line and replaced the section.

Common questions

Slab leaks in Agoura Hills: things people ask

How fast can you get to Agoura Hills?
Often the same day. It's seven minutes down the 101 from Westlake Village.
Who pulls the permit in Agoura Hills?
We do, through the City of Agoura Hills, for water heaters, gas lines, repipes and remodels. We handle the inspection.
Do you have to break up the floor?
For a spot repair, one opening about the size of a coffee table. A reroute runs overhead and doesn't touch the floor.
How long is the water off?
A spot repair is usually a day. A one-line reroute takes one to two days, with the water off only while we connect each end.
Will my insurance cover a slab leak?
Many policies cover the damage and the access work. The pipe usually isn't covered. We give you photos and a written scope for the adjuster.
