A panel replacement quote is a short document carrying a lot of weight. A single line such as “replace 100A panel with 200A, permit included” can describe a one day swap or a project that involves the city, PG&E, new grounding and a meter change. In Concord and the surrounding Contra Costa cities, where many homes still run on original 1950s to 1970s equipment and insurers are asking owners to replace certain panel brands, homeowners are comparing more bids than ever. Two quotes for the same house can differ by thousands of dollars because they describe different jobs, not because one contractor is overcharging.
Quotes that spell out every one of those details are easier to trust, and that is the standard homeowners should expect from any contractor offering electrical panel replacement in Concord. S&B Electric writes its estimates so each line can be checked against the code and the permit, and the team will review a competing bid for free if you want a second set of eyes before signing. Being based in Concord means the crew knows the city’s permit portal, its inspectors and PG&E’s scheduling habits firsthand.

Start With the Header and the Scope Line
The top of the quote sets up everything below it.
- Check the job address against the right permit office. Concord addresses go through the city, while unincorporated areas such as Bay Point or Pacheco go through Contra Costa County. A quote that names the wrong agency will likely miss a fee or a timeline.
- Read the scope wording closely. “Panel replacement,” “like for like replacement” and “service upgrade” are different jobs. PG&E handles each as a separate application type, and only an upgrade usually changes the service conductors or the meter.
- Find the contractor’s license number and confirm who pulls the permit. In California, panel work should be done by a C-10 electrical contractor, and the permit should be in the contractor’s name, not yours.
Read the Amperage and Equipment Lines
This section tells you what is actually going on your wall.
- Compare the existing rating to the new one. Going from 100 to 200 amps is common, but a 125 or 150 amp panel can be the right choice when the load calculation supports it, and PG&E encourages right sizing to avoid unnecessary service work.
- Separate the bus rating from the main breaker. A 225 amp bus with a 200 amp main is normal and leaves headroom. A quote that lists only “200A panel” leaves that detail unclear.
- Note whether the equipment is a combination meter and panel unit mounted outdoors or a separate panel inside. Outdoor meter mains are common here because they put the main disconnect in an accessible exterior spot, which current code expects for one and two family homes on service work.
- Count the circuit spaces. A 40 space panel costs a little more than a 30 space one, but it leaves room for a heat pump, an EV charger or a battery later.
Decode the Breaker Line
Breaker type is where the gap between quotes is usually widest.
- Look for a count, not a phrase. “AFCI and GFCI as required” tells you nothing about price. A good quote lists how many standard AFCI, GFCI and dual function breakers it includes, since dual function breakers can cost several times more than standard ones.
- Expect arc fault protection on circuits that are modified or extended. The 2023 NEC, now adopted in California, ties those requirements to the work being done, so a replacement that touches many circuits can add several of them.
- Confirm a whole home surge protective device appears on the quote. Under the 2023 NEC, replacing service equipment triggers the surge protection requirement in Section 230.67. Quotes that leave it out will likely meet a correction notice at inspection.

Find the Load Calculation
A quote that recommends 200 amps without showing the math is asking you to take its word for it.
- Ask which method was used. Dwellings often use the optional calculation in Section 220.82, while Section 220.87 lets an electrician size added load from a year of real demand data pulled from your PG&E account.
- Check that planned appliances are counted. An EV charger, induction range and heat pump water heater should be listed even if they are a year away.
- See whether load management was considered. A listed energy management system can cap an EV charger’s draw when the house is busy, sometimes keeping an existing service size in place.
Read the Permit and Inspection Lines
Permit fees should appear as their own line, separate from labor. Concord processes building permits electronically through the City of Concord Virtual Permit Center, where you can look up the permit number on your quote and track its status.
- Confirm the fee matches the scope. An upgrade with new service conductors may carry a different fee than a straight swap.
- Expect a final inspection rather than a lengthy series. The inspector typically checks grounding electrodes and bonding to water and gas piping, working clearance in front of the panel (30 inches wide, 36 inches deep), a completed circuit directory and conductor terminations.
- Read the inspection record line by line when it comes back. “Approved” or “finaled” is what an insurer wants. A correction notice lists items to fix, and a fair contract should say the contractor resolves them at no extra cost.
Check the Utility Coordination Line
PG&E involvement is the line most often left vague and most often responsible for delays.
- Look for confirmation that the contractor will file through PG&E’s Your Projects portal and request a load evaluation early.
- Note who handles the meter release. PG&E reconnects only after the city signs off, and reconnection usually happens within about a day of that release.
- Ask what happens if PG&E finds its transformer or service line needs work. That work is scheduled on the utility’s timeline, so the quote should state that this part of the schedule sits outside the contractor’s control.
