Slab leak repair

Most Conejo Valley houses built between 1965 and 1990 have copper water lines in the slab. That copper is fifty years old and starting to fail.
Dan picks up when he can and calls back the same day. Tell him what it's doing and you'll usually get a rough answer on the spot.

“Dan is smart and good at figuring things out. He will stay on it until it's right and he knows his stuff.”
“Dan was quick to respond and explained what needed to be done. The price was fair and we will call him if we have other plumbing needs.”
“Dan and his crew are absolutely the best! Professional, communicative and fair prices. Couldn't ask for anything more!”
The job
How it goes
A slab leak is a water line leaking under or inside the foundation. Soil, concrete, high pressure and hard water all wear the copper thin, and hot lines go first.
We isolate the line with the meter and gauges, and the leak-locating specialist we bring in marks the spot within a foot or so, plus any post-tensioned cables. A spot repair opens the floor there and replaces the bad section. A reroute abandons the line under the slab and runs a new one through the attic, leaving nothing in the concrete.
One leak on a sound line is a spot repair. A second leak within a year or two means the pipe is done, and a reroute beats opening the floor again. We'll tell you which you've got.
Call if
What you notice, and what it usually is
The meter turns with everything off
A pressurized leak. If nothing's visible, it's usually the slab.
Damp carpet or lifting floors with no fixture nearby
Water coming up through the slab.
The water heater runs all the time
Hot water's leaking out, so the tank never catches up.
A second leak a few months after the first
The line is failing. Time to talk about a reroute.
Tell us what it’s doing and we can usually narrow it down on the phone.

What the neighbors say
“Dan's plumbing were fantastic, they installed the AWTOS water sensor our Insurance company sent us, fixed some clogged exterior drains that were blocked, and installed a new trash disposal unit...all for a very competitive price. Thanks guys, we're glad we called you!”
“My 12 year old water heater started leaking yesterday so I texted him, and he called me right away to help me turn off the water and gas. And he was here next day with a new water heater installed.”
“They explain what needs to be done to fix the problem, are willing to do the work asap and take care in keeping the work area clean and unmarred.”
Common questions
Things people ask about slab leak repair
Do you have to break up the floor?
For a spot repair, one opening about the size of a coffee table. A reroute runs overhead and doesn't touch the floor.
How long is the water off?
A spot repair is usually a day. A one-line reroute takes one to two days, with the water off only while we connect each end.
Will my insurance cover a slab leak?
Many policies cover the damage and the access work. The pipe usually isn't covered. We give you photos and a written scope for the adjuster.
Should I repipe the whole house?
After two or three slab leaks, or if you have original copper and plan to stay, yes. For a first leak, repair or reroute that one line.

Leak detection & repair
We find the leak before anything's opened up. Walls, ceilings, floors, slabs and yards.
Copper & PEX repiping
Whole-house repipes in copper or PEX. Your water's off a few hours at a time.
Water pressure regulators
High pressure is behind many fixture failures here. A regulator brings it down to what the house was built for.
