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
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.
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.
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.
If that is what yours is doing (805) 330-3111 Mon–Fri 9–5 Request a visit →
The job
How it goes
We start at the meter. With everything in the house off, a meter that still turns tells us the leak is on the supply side. From there we isolate: hot from cold, inside from irrigation, one branch from another, with the gauge on each. That narrows it to a line, and on most leaks that is enough to find it. When the leak is under a slab we bring in the leak-locating specialist we have worked with for years, who listens for it through the concrete and marks the spot, and the post-tensioned cables if the slab has them, before anyone cuts.
What we find, in this valley, is mostly the same few things. Pinholes in copper that has been in the ground or the slab for fifty years. Slab leaks, which have their own page. Shower pans that have failed and let water into the wall below. A toilet seal. Irrigation lines, which are on the same meter and very often the answer when the bill jumps in summer.
You get the leak located and marked, a plain explanation of what it is, and a price for the repair. Where the pipe is reachable the repair is usually done the same visit. Where it is under concrete or behind tile, the price is in writing before anything is opened.
Call if
What you notice,
and what it usually is
01
The water bill jumped for no reason
A leak somewhere on the supply side. The meter test finds which side in ten minutes.
02
The meter turns with everything off
Same. A leak under pressure, somewhere between the meter and a fixture.
03
A warm spot on the floor
A hot water line leaking under the slab.
04
A ceiling stain under a bathroom
A shower pan, a toilet seal, or a drain joint. Different repairs, so worth finding before the ceiling is opened.
05
The sound of water running when nothing is on
A leak in a wall or under the floor. This is the one we listen for.

Common questions
Leak detection 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.
- Will you have to open walls or floors to find it?
- To find it, no. Locating is done from the outside with the meter and gauges, and under a slab with a specialist locator who marks the spot. The repair may need one opening, and it is marked before anything is cut.
- Could it be the irrigation?
- Often. Sprinkler lines run off the same meter, and a broken lateral or a valve that will not close fully looks exactly like a house leak on the bill. We isolate the irrigation first for that reason.
- Does insurance cover this?
- Policies vary. Most cover sudden damage and the access work to reach the leak, and do not cover the pipe itself. We document what we find, with photographs and the video where there is one, so the claim has what it needs.

- 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.
- 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.
- 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.
