Whole House Rewiring in California

Wiring wears out. Insulation turns brittle, connections loosen and systems installed for a few lamps and a radio now feed air conditioners and computers. Whole house rewiring in California replaces that aging wiring with grounded copper circuits, modern breakers and enough outlets for the way you live now.

Whole House Rewiring cost in California

Whole house rewiring cost in California depends on the size of the home, the number of circuits, how accessible the attic and crawl space are, and whether the panel is replaced at the same time. We walk the house, count openings and give you a written quote. Many owners phase the work, starting with the kitchen, bathrooms and panel.

Whole House Rewiring FAQs

Can I live in the house during a rewire?

Usually. We rewire in sections and restore power to the areas you need each evening. A full rewire of an average home in California takes roughly one to two weeks.

Will you have to tear out my walls?

No. Most cable is fished through the attic, crawl space and wall cavities. We cut small access holes only where there is no other route, and we tell you first.

Is knob and tube wiring dangerous?

It was safe when installed, but it has no ground, its insulation breaks down, and it was never meant to be buried in attic insulation or to carry modern loads. Many insurers also decline to cover it.

Do I have to replace aluminum wiring?

Not always. Where full replacement is not practical, each connection can be repaired with connectors rated for aluminum. We explain both options and the cost of each.

Should I upgrade the panel at the same time?

Often it makes sense, since new circuits need breaker space. See our electrical panel upgrade page, or start with an electrical inspection if you are unsure what the house needs.
