The complete guide to electrical work in West Contra Costa (2026).

A month ago we finished a whole-house rewire on a three-bedroom in San Pablo. 1,500 square feet. Built in the 1940s. Knob-and-tube in the attic, cloth-wrapped branch circuits feeding the bedrooms, a Federal Pacific panel carrying the whole load. The family stayed in a rental for three weeks while we ran new romex through every wall. Final number: $21,000, including the panel, the subpanel, all the circuits, outlets, switches, and the permit.

That is a real job. Every number in this guide comes from a job we actually did, or a job we have quoted in the last six months. No industry averages. No "it depends." If it depends, we tell you what it depends on and what the range is.

West Contra Costa has its own electrical problems. Richmond and San Pablo carry a lot of pre-war housing stock. Pinole and Hercules are mostly 1950s to 1970s tracts. El Cerrito sits in the middle. What these cities share is that the wiring in a lot of these homes is older than most of the people living in them — and that is the market we serve.

Why the jobs we see here skew older

Every city has a wiring vintage, and west Contra Costa's is older than most. North Richmond and the Iron Triangle have housing stock from the 1910s and 1920s. San Pablo is heavy on 1940s war-era tract. Pinole's older neighborhoods run 1950s to 1960s. Hercules is mostly 1970s. El Cerrito is a mix of pre-war craftsman and mid-century ranch. Crockett is its own world — 1890s waterfront sitting next to 1920s worker housing.

What that means in practice: we see knob-and-tube in about one in four Richmond homes we walk. We see Federal Pacific Stab-Lok panels in most pre-1980 houses. We see old cloth-insulated romex in the bedrooms of homes that never had a proper rewire. We see aluminum branch wiring in a small but real share of 1965-1973 houses. Every one of those is a known safety issue, a known insurance problem, or both.

The other thing about west Contra Costa is that a lot of homeowners here have owned their house for decades. The wiring was fine when they moved in, nobody has touched it, and now they are looking at a 2026 insurance renewal letter or a new EV that needs a charger, and the question is what do I actually have to do. That is the conversation this guide is written to support.

Whole-house rewires: what a $21,000 San Pablo job actually looks like

The San Pablo job we finished a month ago is the cleanest example of what a rewire looks like in this county. Here is what that $21,000 number actually bought.

Job file

San Pablo 1,500 sqft · 3 bed · 2 bath

Full whole-house rewire, 1940s pre-war tract home

$21,000

New 200-amp main panel. New subpanel for the kitchen and laundry loads. New romex to every outlet and switch in the house, replacing knob-and-tube in the attic and cloth-wrapped branch circuits in the walls. Modern grounding throughout. Permit pulled with City of San Pablo, passed rough and final inspection. Family stayed in a short-term rental during the three weeks of work. Finish patch-and-paint was a separate trade.

The reason a rewire lands at $21,000 for 1,500 square feet and not $12,000 is that rewiring is slow, labor-intensive work. The panel is maybe ten percent of the cost. The bulk is pulling wire through walls you cannot open up, fishing it through top plates and fire blocks, re-terminating every outlet and switch, and leaving the house ready for the drywall trade to patch where we had to open it.

The 200A panel upgrade — and why PG&E distance decides your quote

A panel upgrade is the most common job we do. Every week we walk a house where the existing panel is a 100-amp Federal Pacific or a 60-amp stab-lok on the side of the garage, and the homeowner wants to run modern appliances, maybe charge a car, and keep their insurance. The fix is a 200A service upgrade.

The thing nobody explains is that a 200A upgrade in west Contra Costa is not one price — it is three. Which tier you land in depends on a single variable: how far your panel is from the utility drop.

On a Richmond job with the existing panel already in the garage and a 6-foot service drop, the quote comes in at $5,000 to $6,000. On an El Cerrito pre-war where the old panel is inside a hallway closet and has to move outside to meet code — 25 feet of new conduit, new grounding rods, patch-up on the wall — we land at $7,500 to $8,000. On a larger San Pablo lot where the service has to cross 40 feet of exterior wall, with PG&E requiring engineering approval on the longer run, the number can reach $10,000 to $12,000.

Level 2 EV chargers: the Pinole and Hercules pattern

EV chargers are the single fastest-growing job category in west Contra Costa. We see them most in Pinole and Hercules — newer tract housing, two-car garages, families that just took delivery of an EV and need the charger installed before the car arrives or the week after.

Pricing on a Level 2 install is also distance-driven, same as the panel upgrade, but the tiers are tighter.

Recessed lighting without tearing the ceiling apart

Recessed lighting pricing is the one place most homeowners get a quote they do not understand the math of. The base number is simple: $250 per can. A typical room — four recessed lights plus a dimmer on a wall switch — lands at about $1,200.

The reason two quotes for the same room can look wildly different is almost always attic access. If we can drop wire from the attic into the ceiling, the job is clean and fast. If there is no attic access — a two-story ranch, a finished second floor, a flat-roof addition — we have two choices: open channels in the ceiling and wall to route the wire (more drywall work, more paint), or run exterior conduit down the outside of the house (ugly). Either way, the price climbs.

What your electrician will not volunteer

Three hidden costs catch homeowners on almost every job if nobody warns them. All three are real, all three are avoidable if you know to ask, and none of them show up on a standard quote.

Permits across West Contra Costa — which cities are faster

West Contra Costa is one of the easier counties in the Bay Area to pull residential electrical permits in. None of the cities here are as busy as Oakland or Berkeley, the queues are shorter, and most jurisdictions turn around a standard residential electrical permit in about a week. That is the baseline across Richmond, San Pablo, El Cerrito, Pinole, Hercules, Albany, El Sobrante, and Crockett.

The permit is the fast part. PG&E is the bottleneck. Any job that requires PG&E to cut the meter — every panel upgrade, every service change — has to wait for their scheduling department, and their schedule is independent of the city's. On a typical job, PG&E shows up a few weeks after the permit is approved. On a worse job, we have waited months. We had one west Contra Costa job where PG&E took eight months from permit approval to the actual meter pull — that is the outer edge, not typical, but it has happened and it is worth knowing before you sign anything.

Three questions to ask before you sign anything

The single biggest mistake we see homeowners make in this county is going with the cheapest quote from an inexperienced contractor. The second biggest is not checking whether the person bidding the job is actually licensed to do it. Both are avoidable with three questions.

What happens when you call us

Start with a phone call. We schedule a walk — no deposit, no charge, no pressure. On the walk we open your panel, open a couple of outlets, look at the service drop, look at the grounding, ask what you are trying to solve. That is when we can tell you, honestly, what the right job is and what it will cost.

You get a written line-item quote the same day or the next. Everything priced out — labor, material, permit, PG&E coordination, inspection — with nothing buried. If you want to compare bids, take ours and go get others. We think that is healthy. We price what we price because that is what the work costs to do right.
