Around here

In Oak Park

With no city hall in Oak Park, a water heater replacement here is permitted through Ventura County. The county runs its own inspection schedule, and we plan the job around it so the date we give you holds. You get a tank with strapping and an expansion tank, or a tankless where the gas line allows, and the old unit leaves with us.

Neighborhoods: the Kanan tracts, Lindero Canyon, the streets off Oak Hills Drive, Sutton Valley, the newer tracts up Bowfield.

01

Cold showers, or a puddle in the garage

Water heater replacement

Tank swap or tankless conversion, with the venting, gas sizing and county permit handled.

02

Buying the same fixture twice

Pressure regulators

Replacing the same fixture usually means the pressure's too high. We check it while we're there.

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.

Common questions

Water heaters in Oak Park: things people ask

How fast can you get to Oak Park?
Often the same day. It's ten minutes up Kanan or Lindero Canyon from Westlake Village.
Who issues permits in Oak Park?
Ventura County, since Oak Park has no city government. We plan around the county's inspection schedule, so the date we give you holds.
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.

Figured out the most straightforward way to fix the problem and got it done. Small footprint, quick results, up and running in no time. Would absolutely recommend.”
