Whole-House Rewiring for Redwood City Homes

If you own one of Redwood City's older homes, rewiring is the conversation that eventually comes up, and where the house sits tells us a lot about what we will find. The downtown and Roosevelt homes built in the 1920s-40s are the most likely to still have knob-and-tube or cloth-insulated wiring behind the walls, the kind that has no ground, dries out over decades, and makes insurers nervous. The 1950s-60s ranches in Woodside Plaza and Farm Hills are often a generation newer but can carry early aluminum branch wiring or a patchwork of additions that never quite matched. Even some Emerald Hills hillside homes have been added onto in ways that left the wiring inconsistent. Fox Electric replaces aging knob-and-tube, aluminum, and cloth-insulated wiring with modern copper and code-current GFCI and AFCI protection, and we fish wire through walls wherever we can to spare your plaster and drywall. We are honest about scope: if your real problem is a couple of ungrounded circuits, pigtailing or a partial rewire may be all you need, and we will say so before quoting a full Redwood City rewire that the house does not require.

Permits & utility in Redwood City

Electrical service for Redwood City 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.

Rewiring in Redwood City means a building permit and electrical inspection through the City of Redwood City Building Division, and because a rewire usually pairs with a panel upgrade, PG&E coordinates the service disconnect and reconnect. Older downtown and Roosevelt homes from the 1920s-40s are the most likely to hold knob-and-tube or cloth wiring, while Woodside Plaza ranches may have aluminum branch wiring that calls for specific connectors. Lath-and-plaster walls in the oldest homes need careful fishing to limit patching. We keep insurance-ready documentation since carriers often ask for proof the old wiring is gone.

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 — Redwood City200A Upgrade

A Redwood City 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 Redwood City — FAQ

How do I know if my older Redwood City home has knob-and-tube wiring?

It is most common in the 1920s-40s homes near downtown and in Roosevelt. Signs include two-prong outlets, no ground wire, ceramic knobs visible in the basement or attic, and fabric-covered cabling. We can confirm it during a walkthrough and show you exactly where it is before recommending any work.

Will you have to tear open all my walls to rewire?

Usually not. We fish new copper through existing wall and ceiling cavities wherever access allows, which limits the openings to small, patchable spots. The older lath-and-plaster homes near downtown take more care, but our goal is always to keep drywall and plaster damage to a minimum and patch what we do open.

My Woodside Plaza ranch has aluminum wiring. Does the whole house need rewiring?

Not always. Aluminum branch wiring can sometimes be made safe with proper connectors and pigtailing at devices rather than a full rewire. We assess how extensive it is and tell you honestly whether a targeted fix or a complete copper rewire is the right call for your specific home.

Does Redwood City require a permit to rewire a house?

Yes. Whole-house rewiring requires a building permit and electrical inspection from the City of Redwood City Building Division. We pull the permit, schedule inspections, and give you the closed-out documentation, which matters both for resale and because insurers often want proof the old wiring was replaced.

Can you rewire while we still live in the home?

In most cases, yes. We plan the rewire room by room and keep circuits energized where we can so you are not without power for long stretches. For the oldest downtown homes with tight access, we will lay out a realistic schedule up front so you know what each day looks like.
