Whole House Rewiring services in San Francisco
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 San Francisco replaces that aging wiring with grounded copper circuits, modern breakers and enough outlets for the way you live now.
Electrical rewiring during a remodel
Open walls are the cheapest time to rewire a house. We coordinate with your contractor's schedule.
Knob and tube wiring replacement
Pre-1950 wiring with no ground and aging insulation taken out of service and replaced with modern cable.
Aluminum wiring replacement
1960s and 70s aluminum branch circuits replaced, or repaired at every connection with approved connectors.
Whole house rewiring
New circuits, grounded outlets, switches, boxes and a labeled panel throughout the home.
Partial home rewiring
Kitchens, bathrooms or the worst circuits first, when a full rewire is not in the budget this year.
Grounding and outlet upgrades
Two-prong outlets replaced with properly grounded or GFCI-protected three-prong receptacles.
Signs a home may need rewiring
- Two-prong outlets and no ground wires
- Cloth-covered or knob-and-tube wiring in the attic or crawl space
- Frequent blown fuses or tripped breakers
- Outlets or switches that are warm, discolored or loose
- An insurer or home inspector has flagged the wiring

San Francisco 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 San Francisco 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.
From recent customers
A 1940s house with original wiring. They rewired it room by room so we could keep living there, and labeled the new panel so clearly even I can read it.
They ran the 50 amp circuit and disconnect for our spa and coordinated the inspection. Neat work, and they showed up when they said they would.
Smart switches, a video doorbell and new neutrals in a few old switch boxes. Everything works with our app and the old three-way finally makes sense.
