Around here

In Oak Park

Every house in Oak Park is on a slab, so leak detection here starts at the meter. Older phases usually have copper leaking under the floor. Newer ones more often have a failed regulator or an irrigation line. We separate the house from the irrigation, then hot from cold, and most leaks are down to one line in the first hour.

Neighborhoods: the Kanan tracts, Lindero Canyon, the streets off Oak Hills Drive, Sutton Valley, the newer tracts up Bowfield.

01

The meter turns with everything shut off

Slab leaks

We find it before any floor comes up, then talk through a spot repair or a reroute.

02

Buying the same fixture twice

Pressure regulators

Replacing the same fixture usually means the pressure's too high. We check it while we're there.

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.

02

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.

Common questions

Leak detection in Oak Park: things people ask

How fast can you get to Oak Park?

Often the same day. It's ten minutes up Kanan or Lindero Canyon from Westlake Village.

Who issues permits in Oak Park?

Ventura County, since Oak Park has no city government. We plan around the county's inspection schedule, so the date we give you holds.

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.
