House Rewiring cost in Kensington, CA.
Whole-home rewiring is priced by square footage, wall and ceiling access, and how much of the house actually needs new wire. Knob-and-tube and aluminum branch wiring drive most rewire demand in San Diego County, often pushed by insurance non-renewal..
What does house rewiring cost in Kensington?
In Kensington, house rewiring runs $10,500–$29,000, with a straightforward job landing near $17,000. Kensington is one of San Diego most cohesive historic neighborhoods, developed in the 1920s and 1930s as a planned Spanish Revival community around Adams Avenue, Marlborough Drive, Kensington Drive, and Terrace Drive. That housing mix is why local pricing sits where it does, not at a flat countywide number. Every quote is flat-rate before work starts, with no trip fee to Kensington.
Why house rewiring costs what it does in Kensington
City of San Diego neighborhoods like North Park, Hillcrest, and Old Town have the county's oldest and most varied housing stock, so this is the widest spread we quote. Pre-1920 pockets still have original knob-and-tube, while 1965-73 homes in La Mesa, Lemon Grove, and National City often carry aluminum branch wiring that insurers are flagging for non-renewal. Finished plaster walls slow access, and a partial rewire targeting just the failed circuits runs well under a full-house job.
- Knob-and-tube still active in pre-1920 pockets of North Park, Hillcrest, and Old Town
- Aluminum branch wiring common in 1965-73 homes, often resolved with COPALUM crimp connectors instead of a full rewire
- Finished plaster wall access in older homes adds patch-and-paint labor
- Insurance non-renewal over knob-and-tube or aluminum wiring is the most common reason this call comes in

Kensington house rewiring cost questions
My insurance company is dropping me over aluminum wiring. Do I need a full rewire?
Not always. If it's just the branch circuits, a COPALUM crimp repair at each connection point often satisfies the insurer for a fraction of a full rewire. We check the full extent of the aluminum run before quoting either way.
Why is the price range so wide for homes in the same neighborhood?
Central San Diego has houses from every decade back to back. One 1920s craftsman might need a full knob-and-tube replacement with plaster repair, and the house next door might just need a partial rewire. We quote after seeing what's actually in the walls.
Can you upgrade my Kensington Spanish home for EV without changing its historic character?
Yes. We conceal conduit and cable through attics and chases, place equipment discreetly, and size a service upgrade for EV and future load in one project. On most homes here the service upgrade comes first because original service is past the wall. The combined service-upgrade-plus-EV project runs $3,900 to $5,700, and we keep everything consistent with the Spanish streetscape.
What does a full rewire cost in Kensington?
A careful staged rewire on a Kensington Spanish home runs $12,000 to $24,000 depending on size, access, and how much finish restoration you want handled. We conceal runs, protect original plaster and tile, and phase the work so the home stays livable.
