Around here

In Agoura Hills

Finding a leak in Agoura Hills depends on which side of the freeway you're on. South of it, Morrison Ranch and Liberty Canyon are seventies and eighties slab houses with copper in the concrete. Old Agoura, north of it, has long private water lines across acre lots, where the wet patch can be far from the leak. We find it from the surface first.

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

Warm spot underfoot in the tract houses

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

We start at the meter. If it turns with everything off, the leak is on the supply side. Then we isolate hot from cold, house from irrigation and branch from branch with gauges. Under a slab, the leak-locating specialist we bring in listens through the concrete and marks the leak, and any post-tensioned cables, before anyone cuts.

Around here it's usually pinholes in fifty-year-old copper, a slab leak, a failed shower pan leaking into the wall below, or a toilet seal. Irrigation shares the meter too, and it's often the answer when the bill jumps in summer.

If we can reach the pipe, we usually fix it that visit. Under concrete or behind tile, you get a written bid before anything's opened.

Call if

What you notice,
and what it usually is

01

The water bill jumped for no reason

A supply leak. A ten-minute meter test narrows it down.

The meter turns with everything off

A leak somewhere between the meter and a fixture.

03

A warm spot on the floor

A hot line leaking under the slab.

04

A ceiling stain under a bathroom

A shower pan, toilet seal or drain joint. We find which before opening the ceiling.

05

Water running when nothing is on

A leak in a wall or under the floor.

    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

Leak detection 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 open walls or floors to find it?
Not to find it. The meter and gauges do that, and under a slab the specialist marks the spot. The repair may need one opening, marked before anything's cut.
Could it be the irrigation?
Often. Sprinklers share the meter, and a broken lateral or a valve that won't close looks like a house leak on the bill. We check irrigation first.
Does insurance cover this?
Policies vary. Most cover sudden damage and the work to reach the leak. The pipe itself usually isn't covered. We give you photos for the claim.
