Whole House Rewiring in Cupertino, CA

Housing stock in and around Cupertino spans a century, which means plenty of homes still have circuits nobody would install today: knob and tube in the attic, cloth insulation crumbling at the box, two-prong outlets with no ground anywhere in sight.

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 Cupertino

Insurance flagged knob and tube

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

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.

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.

Reviews from Santa Clara County

Tesla Wall Connector in the garage, clean conduit run, done in an afternoon. They talked me out of a panel upgrade I didn't actually need.

Devon W.EV charger · Cupertino

Zinsco panel replaced. Straight quote, one day of work, and they handled the utility disconnect scheduling so I didn't have to call anyone.

Yasmin K.Panel replacement · Cupertino

Standby generator install. They sized it to what we actually use rather than the biggest unit, then walked me through the transfer switch and the exercise cycle.

Whole House Rewiring in Cupertino — questions

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.

Can I stay in the house during a rewire?

In most Cupertino 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 Cupertino?

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.

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.

How much does whole house rewiring cost in Cupertino?

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.
