Around here

In Westlake Village

A Westlake Village repipe is nearly always a house with its original copper in the slab that's started to pinhole. The new lines run overhead, through the attic and down the walls, so no concrete comes up. It takes two to four days, with the water off a few hours at a time. The City of Westlake Village handles the permit and inspection.

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.

The job

How it goes

In older houses, galvanized steel rusts shut from the inside, and the water runs brown after sitting overnight. More common here is sixties and seventies copper that's started to pinhole. One pinhole is a repair. Three in two years is a pattern.

Copper is what most of these houses have, and we join it with press fittings, which are faster and cleaner than solder. PEX is flexible tubing from a manifold, one line per fixture. It needs fewer wall openings and doesn't pinhole. Both are permitted and inspected.

A typical house takes two to four days. We work in stages, so the water's back on every evening. Drywall openings are small, and each one is listed on the bid. You stay in the house.

Common questions

Repiping 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.
Copper or PEX?
Both work. Copper is what buyers expect. PEX goes in faster with fewer openings and doesn't pinhole. In a slab house, either one runs overhead. We can bid both.
How long is the water off?
A few hours at a time, and it's back on every evening.
Do I need to move out?
No. It's noisy for a few days and some walls get small openings.

“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.”
