Whole-House Rewiring for San Mateo Homes

Rewiring is the job that tends to surface when a San Mateo home changes hands or finally gets the remodel it has needed for decades. The city's oldest housing sits in San Mateo Park and Aragon, where pre-war homes can still hide cloth-insulated wiring or even knob-and-tube behind newer drywall. The big stock of 1940s-60s homes in Baywood, Hillsdale, and Beresford brings its own issue: early branch circuits, two-prong ungrounded outlets, and the occasional run of aluminum wiring that insurers now flag. None of that was unsafe when it was installed, but it does not meet what a modern household and current code expect. Fox Electric replaces aging wiring with modern copper and code-current GFCI and AFCI protection, and we fish wire through walls to keep drywall damage to a minimum rather than gutting the house. Many of these San Mateo homes are slab-built down in the bay-side neighborhoods like Shoreview and Fiesta Gardens, which limits attic and crawl access, so we plan the routing around how the house is actually framed. Where a full rewire is overkill, we say so. Sometimes the right call is targeted: pigtailing aluminum connections or rewiring the specific circuits that are a problem, not the whole house.

Permits & utility in San Mateo

Electrical service for San Mateo is provided by PG&E, and the electrical permit and inspection go through the local building department. We pull the permit and coordinate the PG&E service work as part of the job.

A San Mateo rewire requires a building permit and electrical inspection through the City of San Mateo Building Division, and PG&E coordinates any service disconnect if the panel is replaced at the same time. The slab-built homes common in Shoreview, Fiesta Gardens, and Hayward Park limit attic and crawl access, so routing is planned carefully to avoid unnecessary drywall work. Pre-war San Mateo Park and Aragon homes may turn up knob-and-tube or cloth wiring mid-project. Insurers often want documentation that aluminum or knob-and-tube has been replaced, and we provide inspection-backed paperwork for that.

Pricing depends on your home and scope — we give a free on-site estimate with a written, fixed price before any work starts. For typical Bay Area ranges, see our guide on knob-and-tube wiring replacement.

Recent Project

200A Panel Upgrade — San Mateo200A Upgrade

A San Mateo homeowner needed more capacity for an EV charger and a future heat pump, but the home was still on its original 100A service. We ran a load calculation, pulled the city permit, coordinated the PG&E service window, and installed a 200A panel — every circuit relabeled and the directory typed, powered back up the same day.

Before: Original 100A service, no room to grow
After: 200A panel sized for EV + heat pump headroom
Coordination: PG&E disconnect/reconnect + city inspection handled
Outcome: Passed inspection, permit closed out for resale

Questions

Whole-House Rewiring in San Mateo — FAQ

How do I know if my older San Mateo home needs rewiring?

Warning signs include two-prong ungrounded outlets, a fuse box, warm or discolored switch plates, and breakers that trip under normal load. Pre-war homes in San Mateo Park and Aragon may have knob-and-tube or cloth wiring, and some 1960s homes have aluminum branch circuits. We assess it during a walkthrough and tell you whether a full rewire or targeted repairs make sense.

Can you rewire without tearing apart my walls?

Usually we can keep the damage limited. We fish new copper wiring through existing wall and ceiling cavities wherever the framing allows, opening small access points rather than entire walls. On slab-built San Mateo homes in Shoreview or Fiesta Gardens with tight attic and crawl access, we plan routing carefully and patch what we do open.

Do I really need a whole-house rewire, or can you fix just the problem areas?

It depends on what is wrong. If only certain circuits or aluminum connections are the issue, targeted rewiring or pigtailing is often the smarter, cheaper fix. We will not push a full rewire your San Mateo home does not need. If the wiring is failing throughout, we will be straight with you about that too.

Will my insurer want proof the old wiring was replaced?

Often, yes. Insurers frequently ask for documentation that knob-and-tube or aluminum wiring has been remediated before they will write or renew a policy. Fox Electric pulls the permit, passes the City of San Mateo inspection, and gives you the closeout paperwork your insurer needs.

Does a San Mateo rewire need a permit?

Yes. Rewiring requires a building permit and electrical inspection through the City of San Mateo Building Division. We handle the permit application, scheduling, and inspection, and if the panel is replaced at the same time we coordinate the PG&E service disconnect and reconnect.
