Around here

In Westlake Village

In Westlake Village, finding a leak usually starts with the water bill or a warm spot on the floor, since houses here went up from 1967 on with the water lines in the slab. We start at the meter and split off the irrigation, then hot from cold. Under a slab, the locator we work with marks the spot before anything gets cut.

Neighborhoods: First Neighborhood, Westlake Island, North Ranch, Three Springs, Southshore, the streets off Lindero Canyon.

01

A warm spot on the floor

Slab leaks

We find the leak before anything gets opened up. Then it's a spot repair or a reroute, depending on the rest of the pipe.

02

Another leak a few months after the last

Copper pinholes

One leak is a repair. Three in a year usually means the pipe is done. We'll tell you which one you've got.

03

Faucets and valves that keep failing

Pressure regulators

When angle stops and toilet valves keep failing, the pressure's often too high. The regulator is a small part.

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 Westlake Village: things people ask

How fast can you get here?
Often the same day. We're five minutes away, so a small job can sometimes fit between two others. Call and Dan will give you a time.
Who pulls the permit?
We do, through the City of Westlake Village, for water heaters, gas lines, repipes and remodels. The work gets inspected, and the paperwork stays with the house.
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.

“Outstanding work! Did a terrific job of diagnosing the issue over the phone prior to repair. Plumber was on time and on point. Work was done quickly and thoroughly. Figured out the most straightforward way to fix the problem and got it done. Small footprint, quick results, up and running in no time. Would absolutely recommend.”
