Plumber in Westlake Village

5.0 on Google (20 reviews) CSLB Lic. #339618 Family shop since 1977

Our shop is in Westlake Village, and we're in houses here every week. Almost all of them sit on a slab, and that shapes most of our calls.

The shop's on Hillsbury Road, so we're often out the same day. If Dan can't pick up, he calls back that day. You get the price before we start. Nobody here works on commission. Monday to Friday, 9 to 5.

Why it happens

What Westlake Village is plumbed with

Almost every house in Westlake Village sits on a slab, with the water lines in or under the floor. When that sixty-year-old copper fails, there's no drip to see. You notice a warm spot on the floor, a meter that keeps turning with everything off, or a water bill that jumps.

The town was built in phases. First Neighborhood and the streets around the lake date from the late sixties. North Ranch is later, with bigger houses. We usually know roughly how old your pipe is before we arrive.

Streets and pockets we work in: First Neighborhood, Westlake Island, North Ranch, Three Springs, Southshore, the streets off Lindero Canyon.

Most weeks

What people in Westlake Village call about

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.

04

No hot water, or never enough

Water heaters →

Tank or tankless, even in tight garage closets. We strap and vent it, pull the permit and haul the old one away.

Dan's been under some of these houses twice, in the eighties and again for the next owner.

Two 50-gallon tanks, one of them leaking

Two 50-gallon heaters in a garage, with a puddle under one. Over two days we drained both, put in one large tankless unit with the gas and venting sized for it, and tested every joint with a digital gas meter.

A sewer cleanout where there was none

The building's drain line had no cleanout, so every clearing went through a fixture. We trenched about ten feet down with shoring, cut in a combination fitting and brought a new cleanout up to grade.

Common questions

Things people in Westlake Village ask

Do you cover all of Westlake Village?

Yes, both the Los Angeles County side around the lake and the Ventura County side toward North Ranch. That's 91361 and the Westlake Village part of 91362.

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.

How does pricing work in Westlake Village?

You get the price before we start. Repairs are our time plus parts, and bigger jobs get a written bid. Nobody here works on commission.

Why are slab leaks so common in Westlake Village?

The houses date from 1967 on, with copper in or under the slab. That copper's fifty to sixty years old, the water's hard, and pressure is high on many streets. Hot lines go first.

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.
