Around here
In Thousand Oaks
Repipes in Thousand Oaks come from the older east-side tracts, where sixties and seventies copper has pinholed more than once. The newer Lang Ranch houses almost never need one, and we'll tell you so. New lines run overhead in copper or PEX, with the water off a few hours at a time. The permit goes through City of Thousand Oaks Building and Safety.
Neighborhoods: Lang Ranch, Sunset Hills, North Ranch, the Westlake side of the boulevard, the older tracts off Erbes Road, central Thousand Oaks, Newbury Park.
A water bill that jumped
We find it first. One bad spot and the start of a pattern are very different jobs.
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 Thousand Oaks: things people ask
How fast can you get to Thousand Oaks?
Often the same day. The east side is ten minutes from the shop, and Newbury Park is the far end. Call and Dan will give you a time.
Does the oak tree ordinance affect a sewer repair?
It can. The city protects oaks and their root zones, so a trench can't always take the shortest route. We locate the line from the surface and plan around the trees first.
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.
What people say
“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.”
“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!”
“Dan's Plumbing did excellent job for us replacing our broken water pressure regulator. Quick response, good price, great quality of work. Will hire them again.”

Pressure regulators in Thousand Oaks
Pressure regulators in Thousand Oaks hold back street pressure that comes in above the 80 psi the code allows on the east side, and higher above Lang Ranch. When one fails, fill valves, angle stops and faucet cartridges go one after another. In December 2025 a shower valve here needed a new cartridge and the regulator had failed too, so we replaced both.
Slab leaks in Thousand Oaks
Most slab leaks in Thousand Oaks come from the sixties and seventies tracts off Erbes Road and along Westlake Boulevard, with the copper in the concrete. Lang Ranch houses are thirty years younger and rarely have one. Once the leak-locating specialist we bring in marks the spot, it's a spot repair or a reroute overhead.
