Water Heater Repair Across Contra Costa County
12 cities, one licensed plumber, 38 years of doing it from the same Concord shop.
One plumber, 12 cities, about 604,000 residents
Phillips Water Heater Service works out of one shop in Concord, and that single fact shapes everything on this page. Dan Phillips has held California plumbing license #525190 since 1988 and still does the work himself, so the service area is defined by how far one van can reasonably get in a morning — not by how many ZIP codes a marketing page can list.
In practice that means the whole central spine of Contra Costa County: Concord and Pleasant Hill at the centre, Martinez and Clayton on either shoulder, the I-680 corridor south through Walnut Creek to Alamo, Danville, and San Ramon, the Lamorinda hills of Lafayette, Orinda, and Moraga, and east to Antioch. Each city below has its own page with the neighbourhoods, landmarks, and the specific plumbing problems that come up there. This page exists so you can find yours quickly, and so you can see honestly how long we are likely to take to reach it.
The arrival windows are measured from the Concord base and are the real ones. A no-hot-water call in Concord is usually a 15 to 30 minute drive. Antioch is 35 to 55. Nobody is going to tell you “30 minutes anywhere in the county”, because that is not how driving to Antioch works.

What actually changes from city to city
The equipment is the same everywhere. What differs is the housing stock and the ground it sits on, and after 38 years the pattern is predictable enough to plan around:
Hillside pressure
Lafayette, Orinda, Moraga, Clayton and the Martinez ridges sit on slopes, which means pressure regulators matter and a failing one shortens a water heater’s life well before its warranty runs out.
Clay soil and slab leaks
Orinda and Antioch both move with the seasons. Slab leaks there are a soil story rather than a plumbing-quality story, and finding them without opening the whole floor is most of the work.
Older galvanized supply
Concord’s ranch homes and parts of Moraga still have galvanized pipe. It is worth knowing before a water heater swap, because new equipment on old supply lines exposes the weakest section.
Permits and HOAs
Permit fees are set city by city, and Walnut Creek HOAs — Rossmoor especially — have their own water heater standards. Both are easier to handle before the old unit is already on the driveway.
Common questions
Do you charge extra to travel to the edges of Contra Costa County?
No. The price you are quoted is the price for the job, whether you are five minutes from our Concord base or out in Antioch. What changes with distance is how quickly we can be at your door, not what you pay.
Which cities can get same-day water heater service?
All of them, if you call early enough in the day. Central county — Concord, Pleasant Hill, Martinez, Walnut Creek, Clayton — has the best odds because arrival times are shortest. For Antioch, San Ramon, and the Lamorinda hills, calling before midday makes same-day far more likely.
Is it really Dan who shows up?
Yes. This is an owner-operated business with one licensed plumber, so the person who answers the phone is the person who does the work. That is the reason there are no call centers and no subcontractors, and it is also why arrival windows are honest rather than optimistic.
Do you pull permits for water heater replacements?
Yes, where the work requires one. Permit requirements and fees are set by each city or by county building services for unincorporated areas, so they differ across the county. We handle the filing and the inspection as part of the job.
No hot water somewhere in the county?
