## Whole House Rewiring in San Mateo, CA

Insurers across San Mateo County have grown strict about knob and tube and aluminum branch wiring, and some will not write a policy at all. Rewiring a San Mateo home resolves that, and it is the only fix that actually addresses insulation that has gone brittle.

Call (833) 652-8933 and describe what is happening. If it is a same-day job we will book it today, and if it needs a site visit to quote properly we will tell you that too.

## Situations we see in San Mateo

### Aluminum branch wiring

Aluminum expands and creeps at terminations and runs hot. Depending on scope we either replace the runs or pigtail every connection with approved connectors.

### Fabric insulation crumbling

Once the cloth and rubber goes brittle, conductors sit bare inside boxes. There is no repair for that other than new wire.

### Two-prong outlets everywhere

No equipment ground means no fault path. Rewiring the branch circuits is the real fix, though GFCI protection is a legitimate interim step in some cases.

### Insurance flagged knob and tube

Carriers in San Mateo County increasingly require removal. We document what was replaced so you have something to send the underwriter.

## Reviews from San Mateo County

★★★★★

We needed a 200 amp panel before our EV charger install. They did the load calculation, pulled the permit, and had the whole thing done and inspected in a week.

Hot tub circuit and disconnect. Permit, inspection, everything. Showed up when they said and cleaned up after.

★★★★★

Bought a 1948 house with cloth wiring. They phased the rewire so we always had power in half the house, and gave us paperwork our insurer accepted.

## Whole House Rewiring in San Mateo — questions

Will you cut up my walls?

Some openings are unavoidable, but we fish through existing cavities wherever we can and keep openings small, straight and in patchable locations. We tell you where they will go before we cut.

Do I need a new panel if I rewire?

Usually. New circuits need somewhere to land, and a rewire is the natural moment to move to a 200 amp panel with AFCI protection.

How much does whole house rewiring cost in San Mateo?

It scales with square footage, number of circuits, attic and crawlspace access, and whether the walls are plaster or drywall. A 1,200 square foot single story with attic access is a very different number than a two-story plaster home. Call (833) 652-8933 for a walkthrough and a firm scope.

Can I stay in the house during a rewire?

In most San Mateo projects, yes. We work in phases and leave you with power in the rooms we are not touching that day.

Is knob and tube wiring illegal in San Mateo?

Existing installations are generally allowed to remain, but you cannot extend them, most insurers dislike them, and the insulation is long past its service life. That combination is why owners replace it.
