Around here
In Thousand Oaks
The late-nineties Lang Ranch houses in Thousand Oaks are all coming up on their second water heater at once. We replace tanks with strapping and an expansion tank under a City of Thousand Oaks permit. In October 2025 we took a tank out of a garage here and set a condensing tankless in its place.
Neighborhoods: Lang Ranch, Sunset Hills, North Ranch, the Westlake side of the boulevard, the older tracts off Erbes Road, central Thousand Oaks, Newbury Park.
The job
How it goes
No hot water from a gas heater is usually the thermocouple, pilot assembly or gas valve, and that's a repair if the tank is sound. Water on the garage floor means the tank has rusted through, and the heater is done.
Replacement takes most of a day. We fit new flex connectors and a new gas connection, strap it top and bottom as California requires and check the vent. Houses with a pressure regulator, which is most of them here, get an expansion tank. We haul the old one away and handle the permit.
We install 40 and 50 gallon gas units as standard, and bigger ones where needed. Tankless has its own page.

Recent jobs
Tank to tankless, and a fire pit line tested
Swapped a tank heater for a condensing tankless unit. We also capped the fire pit gas line, pressure-tested it at 10 psi for fifteen minutes and hooked up the owner's fire ring.
A shower leak that turned out to be pressure
A leaking shower valve got a new cartridge. The house's leak-monitor app showed high pressure, so we tested the regulator at the front of the house, found it had failed and replaced it.
A gas smell outside the dining room
On the Westlake side of town. Dug down to a hole in a half-inch galvanized gas pipe and replaced the horizontal run. With the gas back on, a second leak showed up where the pipe enters the house, so we shut it off again for the next stage.

Common questions
Water heaters 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.
Does a water heater need a permit?
Yes, in every city and county we work in. It covers the gas, venting and seismic strapping, and it matters when you sell.
How long does a replacement take?
Most of a day, with no hot water for about half of it.
Tank or tankless?
A tank is the simpler swap. A tankless is a bigger install, since the gas and venting usually change, but it doesn't run out and lasts about twice as long. We can bid both.
What people say
“When I called him out and he immediately came my house within 2 hours and did a really quick and great job for my bathroom.”
“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!”
“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.”

Tankless in Thousand Oaks
Tankless work in Thousand Oaks is mostly conversions, and the gas line from the meter gets upsized for a whole-house unit.
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.
