The service
What electrical panel upgrade & rewiring is, what a visit covers and where the line is.
The short answer
An electrical panel upgrade replaces the service panel and often the meter base and service cable, so your home can carry more load safely. Electrical Panel Upgrade & Rewiring in San Mateo is booked through pros who cover its 3 ZIP codes, in neighborhoods such as Baywood, Hayward Park, and Bay Meadows. In San Mateo, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. Each panel job is quoted by the pro you choose, who also sets the workmanship warranty.
If electrical panel upgrade & rewiring is an emergency
A panel that smells hot, buzzes or shows scorch marks can be heading toward a fire. Reduce load and call for help rather than waiting for the next scheduled visit.
Treat it as urgent if
- A burning smell or visible scorch marks around the panel or a breaker
- A buzzing or crackling sound from the panel
- A breaker that is hot to the touch or will not stay reset
- Lights that flicker or dim whenever a large appliance starts
- Water running into the panel or meter base

What shapes a electrical panel upgrade & rewiring job
These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.
Choosing service size and scope
The right panel size depends on your load calculation, your plans and your existing equipment. Sizing for the next several years now can avoid reopening the service later. Tap an option to compare, then add your pick to your job notes.
What is not part of electrical panel upgrade & rewiring
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Utility-owned equipment. The meter, the lines up to the meter and the transformer belong to the utility, and it handles any work on them.
- Drywall repair, plaster patching and painting after wiring is fished through walls. Those are separate services on NorTech.
- Solar, battery backup and generator interconnection, which have their own services and their own sizing.
- A panel project that reaches $1,000 in labor and materials goes to a licensed contractor. Panel and rewiring work is always done by pros who hold the electrical license.
- Asbestos or lead paint abatement found while opening walls in an older home. That needs a qualified abatement pro before work can continue.
License and permits for electrical panel upgrade & rewiring
Replacing a panel, changing the service or rewiring branch circuits is licensed electrical work. The pro who takes this job holds the electrical license, and homeowner-level DIY on a panel is not safe even with the main off.
Panel replacement, service upgrades and substantial rewiring commonly need a permit and an inspection, and the utility often reconnects power only after approval. Your pro pulls the permit and arranges the inspection, and tells you what it covers.
Check the license on the pro profile before you book, and ask for the permit number and the final inspection sign-off when the work is done. Keep both with your home records for insurance and resale.

Before you book electrical panel upgrade & rewiring
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Photograph the panel and meter
Take clear photos of the closed panel, the label on the door, the meter and the outside service. The pro can then tell you what is likely needed before the visit.
List everything you may add in ten years
EV charger, heat pump, hot tub, induction range, workshop or addition each add load. Putting them on the list now avoids planning a second service change.
Plan for a day without power
Power is disconnected during a panel swap. Arrange for fridge contents, sump pumps, medical devices, work equipment and pets, and tell the pro about anything that cannot lose power.
Clear access to the panel and meter
Move boxes, shelves and stored items at least a few feet from the panel. Unlock gates, garages and utility rooms so the pro can reach everything without delay.
Ask about the permit and inspection plan
Confirm the pro will pull the permit, schedule the inspection and give you the paperwork. Ask who contacts the utility for disconnect and reconnect.
Ask what is not included
Wall patching, painting and trenching are often separate. Ask the pro how they handle them so the final price has no surprises.
Say where in San Mateo you are
