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.

Why it happens
What Westlake Village
is plumbed with
Almost every house in Westlake Village sits on a concrete slab, so the water lines run in or under the floor. When sixty year old copper starts to go you often get no warning at all. There is no drip under a sink and no stain on a ceiling. What you notice is a warm patch underfoot, or the meter still ticking over after you have turned everything off, or a bill that is suddenly much higher than it should be.
The town was planned before it was built, so the phases are easy enough to read off the plumbing. First Neighborhood and the streets around the lake went in from the late sixties. North Ranch came later and the houses are bigger. That helps, because we can usually tell roughly how old your pipe is before we get there.
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
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.
03
Faucets and valves that keep failing
Pressure regulators →If your angle stops and toilet valves keep giving out, the pressure is often too high. The regulator is an inexpensive part.
04
No hot water, or never enough of it
Water heaters →Tank replacements and tankless conversions, including the tight garage closets these houses tend to have. We strap it, vent it, pull the permit and take the old one away.
Danny has been under some of these houses twice, once in the eighties and again for whoever bought it later.

July 2026
Two 50-gallon tanks, one of them leaking
A garage with two 50-gallon heaters and a puddle under one. Drained both and replaced the pair with a single large tankless unit, with the gas and venting sized for it, then tested every joint with a digital gas meter. Two days.

August 2026
A sewer cleanout where there was none
A building with no cleanout on its drain line, so every clearing had gone through a fixture. Trenched about ten feet down with shoring, cut in a combination fitting and brought a new cleanout up to grade. The next clearing takes an hour.

April 2026
Earthquake and leak shutoffs at the front of the house
A seismic gas shutoff valve on the meter with a stabilizer bracket, and a smart water shutoff with a pressure relief valve on the main. The house now closes its own valves.

Inside Westlake Village
The neighborhoods,
and what is different in each
- First Neighborhood The first tract built in Westlake Village, from 1967 on. The houses are the same age as the company, and so is a lot of the copper in them.
- Westlake Island A guard-gated island in the middle of Westlake Lake. Half the houses are 1970s originals on slab, and half have been rebuilt or remodeled to the studs, sometimes next door to each other.
- North Ranch The country club side of Westlake Village, built from the mid-seventies on and across the city line into Thousand Oaks. Bigger houses, longer runs, and more plumbing than anyone has a record of.

Common questions
Things people in Westlake Village ask
- Do you cover all of Westlake Village?
- Yes. The Los Angeles County side around the lake and the Ventura County side toward North Ranch. Zip code 91361, and the Westlake Village streets that carry 91362. The shop is on Hillsbury Road, in the middle of it.
- 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.
- How does pricing work in Westlake Village?
- You get the price before we start. Repairs are our time plus parts, and remodels, repipes and additions get a written bid. Nobody here works on commission.
- Why are slab leaks so common in Westlake Village?
- The houses went up from 1967 on with the copper water lines run in or under the concrete slab. That copper is now fifty to sixty years old, the water here is hard, and street pressure on many streets is high. Hot lines go first. Finding it early keeps the work to the pipe.
- 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.

By the job
What we do in Westlake Village,
job by job
- Leak detection & repair 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 leak repair 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 heater repair & replacement 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.
- Copper & PEX repiping in Westlake Village A Westlake Village repipe is nearly always a house with its original copper in the slab that has started to pinhole.
- Water 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.
- Plumbing 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 water heaters 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 inspection & sewer 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.
- Gas line installation & repair 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.
