Electrical rewiring in San Francisco, CA
Rewiring is the least glamorous and most consequential electrical work there is. In older San Francisco neighborhoods we still find knob and tube, cloth-insulated conductors and ungrounded two-prong outlets carrying loads nobody imagined in 1948. A rewire replaces the wiring itself rather than patching around it.

Whole House Rewiring across San Francisco
We cover every part of San Francisco — the Marina, SoMa, Bernal Heights and Noe Valley included — along with the neighboring communities of Millbrae and San Bruno.
San Francisco sits in San Mateo County, and the electrical work here reflects that mix: older housing stock that needs grounding, capacity and device upgrades, alongside newer construction that simply needs more circuits than it was built with. Crews route through the Peninsula daily, so travel time to a call in San Francisco is short.

Recent San Francisco feedback
We rewired in stages so we could keep living here. They planned the access holes where the patcher could actually fix them, which I did not expect.
Ellen and Ray M.San Francisco, CASmart switches finally work because they pulled neutrals into the boxes. Two other installers had told me it was not possible.

Dan K.San Francisco, CAWhole House Rewiring in San Francisco — questions we get asked
Is aluminum wiring dangerous?
Aluminum branch wiring from the 1960s and 70s is not inherently unusable, but its connections loosen and overheat over time. Remediation with listed connectors or replacement resolves it.
How do I know if I have knob and tube wiring?
Look in the attic or basement for individual wires running through white ceramic knobs and tubes. Two-prong outlets throughout and a fuse box are strong supporting signs.
How much does it cost to rewire a house in San Francisco?
Whole-home rewires in San Francisco are priced by square footage, circuit count and access — a single-story home with an accessible attic and crawlspace costs far less than a two-story plaster home. We walk it, then give one firm number.
Do I have to move out during a rewire?
Usually not. We work in phases and keep power on to the areas you are using. Larger San Mateo County projects sometimes have a day or two where it is easier to be elsewhere.
Will you patch the drywall?
We cut planned, patch-ready access and coordinate closely with your patcher or painter. Ask and we will quote the rewire with patching included.
