Home rewiring, knob & tube and aluminum wiring replacement in Castro Valley, Alameda County. Local electricians, upfront pricing and fast scheduling.
(833) 652-8933 Request a quoteMany houses in Castro Valley still run on wiring installed fifty to a hundred years ago. Knob and tube, cloth-covered wire, ungrounded two-prong outlets and 1960s aluminum branch wiring all raise fire risk and make insurance harder to get. Phasethree Electric rewires homes throughout Castro Valley and Alameda County, working room by room so you can stay in the house while we work.
We map every circuit, plan new home runs to the panel, fish new copper wiring through walls and ceilings using small access openings, install grounded outlets, GFCI and AFCI protection where code requires, and patch openings ready for paint. The job finishes with a city inspection.
Knob and tube cannot be buried in insulation and has no ground. Aluminum wiring loosens at connections and overheats. In Castro Valley we either replace these fully or, for aluminum, use approved copper pigtail connectors as an interim fix.
Pricing is based on square footage, number of circuits, accessibility of attic and crawlspace, and whether a panel upgrade is bundled. Call (833) 652-8933 for a walkthrough in Castro Valley or nearby San Lorenzo, Hayward, San Leandro, San Ramon.
