A warm patch on the floor
Slab leaks
We find the leak before anything gets opened up. After that it is a question of repairing the one spot or rerouting the line, and that comes down to the condition of the rest of it.

What this job looks like
in Westlake Village
A Westlake Village repipe is nearly always a house with its original copper in the slab that has started to pinhole. The new lines run overhead, through the attic and down the walls, so no concrete comes up. Two to four days, water off a few hours at a time, permit and inspection through the City of Westlake Village. Copper or PEX, and we say which we would put in your house.
Streets and pockets we work in: First Neighborhood, Westlake Island, North Ranch, Three Springs, Southshore, the streets off Lindero Canyon.
02
Another leak a few months after the last
Copper pinholes
One leak on its own is a repair. Three in a year usually means the pipe itself is going, and we will tell you which situation you are in.

The job
How it goes
Two kinds of house need it. The older ones with galvanized steel, which rusts closed from the inside over decades, so the pressure falls slowly and the water runs brown after the house has stood overnight. And the far more common one here: sixties and seventies copper that has started to pinhole. One pinhole is a repair. Three in two years is a pattern, and each repair is buying a few months.
Copper or PEX. Copper is what most of these houses have, it is rigid, and it is joined with press fittings now instead of solder, which is faster and cleaner in a finished house. PEX is flexible tubing run from a manifold, so each fixture has its own line, it pulls through walls with fewer openings, and it does not pinhole. Both are permitted, both are inspected, and both come with a written scope that lists every line. We say which we would put in your house, and why.
A typical house is two to four days. We work it in stages so the water is off for a few hours at a time and back on every evening. Openings in the drywall are kept small and marked, and every one is listed on the bid so there is no surprise about what needs patching afterward. You stay in the house.

What you notice,
and what it usually is
01
Brown water first thing in the morning
Galvanized pipe rusting inside. The pipe is closing up.
02
Pressure that has slowly dropped over years
Same. The bore of the pipe is getting smaller.
03
The third pinhole leak in a couple of years
The copper is at the end of its life. Each repair is buying a few months.
04
Blue-green stains at fixtures
Copper dissolving into the water, usually from high pressure and age.

Buying or selling a house with original pipe
A repipe with a permit and an inspection card is worth more than the same house without one.

03

Common questions
Repiping in Westlake Village: things people ask
- How fast can you get here?
- Often the same day. Westlake Village is a five minute drive from the shop, so a small job can sometimes fit between two others. Say what it is doing when you call and Danny will tell you straight away when he can be there.
- Who pulls the permit?
- We do, through the City of Westlake Village, for water heaters, gas lines, repipes and remodel plumbing. The inspection is part of the job and the paperwork stays with the house.
- Copper or PEX?
- Both are good. Copper is what the house was built with and what a buyer expects to see. PEX is quicker, needs fewer openings and never pinholes. In a slab house where the old lines are in the concrete, either one gets rerouted overhead. We bid whichever fits the house, and both if you want to compare.
- How long is the water off?
- A few hours at a time, and on every evening. We sequence the work so the house keeps running.
- Do I need to move out?
- No. It is noisy for a few days and there are openings in some walls, and that is the extent of it.

- Leak detection in Westlake Village Westlake Village houses were built from 1967 on with the water lines in the slab, so a leak here usually shows up on the bill or as a warm patch on the floor before anyone sees water. We start at the meter, isolate hot from cold and the house from the irrigation, and narrow it to a line. Under a slab we bring in the locator we work with to mark the spot before anything is cut. Five minutes from the shop.
- Slab leaks in Westlake Village Slab leaks are the most common serious leak we see in Westlake Village, for a plain reason: 1967-era copper under a slab, hard water, and street pressure that runs high on many streets. Once the locator has marked it, the choice is a spot repair through one opening or a reroute overhead, and the condition of the rest of the line decides which. We say which we would do in your house before you decide.
- Water heaters in Westlake Village Most Westlake Village heaters live in a garage closet sized for a 40-gallon tank in 1970, which limits what fits and how it vents.
- Drain cleaning in Westlake Village The original drain lines in Westlake Village are cast iron or early ABS, and the sewer laterals out to the street are fifty years old.
- Pressure regulators in Westlake Village The water reaches Westlake Village from tanks on the hills, so on a lot of streets it arrives well above the 80 psi the code allows in a house.
- Repairs in Westlake Village Westlake Village is where the shop is, on Hillsbury Road, so the small jobs here are the ones we do most.
- Tankless in Westlake Village Most Westlake Village houses keep the water heater in a garage closet sized for a 40-gallon tank in 1970, and a tankless hangs on that wall.
- Sewer camera & repair in Westlake Village Westlake Village went up from 1967 on, so the sewer laterals out to the street are around fifty years old, cast iron or early ABS depending on the year. The camera goes in at the cleanout and runs to the street, you watch it with us, and the transmitter on the head marks the fault and its depth on the surface. Plenty of houses here were built without a cleanout at all. In August 2026 we put one in on a line that had none, trenching about ten feet down with shoring and cutting in a combination fitting. The next clearing on that line takes an hour.
- Gas lines in Westlake Village Gas work in Westlake Village comes in a few kinds. New lines out to a BBQ, a fire pit, a range or a pool heater, sized for the appliance and the length of the run. Upsizing from the meter when a tankless goes in, which is most of the conversions here. Repairs and leak tests. In April 2026 we fitted a seismic gas shutoff valve on a meter here with a stabilizer bracket, and a smart water shutoff with a pressure relief valve on the main. Every line is tested under pressure and inspected, permit through the City of Westlake Village. If you smell gas, leave and call SoCalGas first.
