A whole-house rewire replaces all outdated wiring (knob-and-tube, cloth-covered Romex, or aluminum branch circuits) with modern 12/2 and 14/2 NM-B copper wiring to meet current California Electrical Code. Many Sacramento-area homes built before 1970 still have knob-and-tube wiring that is a fire hazard and prevents proper insulation. The project includes running new wiring from the panel to every outlet, switch, and light fixture; upgrading receptacles to tamper-resistant and GFCI/AFCI-protected circuits; and patching drywall access holes. Most 3-bedroom homes are completed in 3-5 days.

Hercules se encuentra en el condado de Contra Costa (East Bay). Waterfront community with newer planned developments and bayfront living. El proveedor local de energia es PG&E.

Codigo de Construccion de California

California Electrical Code (NEC 2023) requires AFCI protection on all 15A and 20A branch circuits in dwelling unit living areas, bedrooms, hallways, closets, and similar spaces. GFCI protection is required in kitchens, bathrooms, garages, outdoors, laundry, and within 6 feet of any sink. Tamper-resistant receptacles are required throughout.

Cronograma del Proyecto

Assessment & Circuit Mapping

2-4 hrs

Map all existing circuits, identify wiring types and hazards (knob-and-tube, aluminum, or damaged insulation), count outlets and fixtures, and plan the new circuit layout per NEC requirements.

Access & Old Wire Removal

1-2 days

Cut access holes in walls, ceilings, and floors at strategic points. Remove old wiring from accessible runs. Abandon in-wall wiring that is inaccessible by disconnecting it from the panel and cutting it at every box.

New Wiring Installation

Whole-House Rewire en Hercules — Preguntas Frecuentes

How much does a whole-house rewire cost in Sacramento?+

A full rewire for a 3-bedroom, 2-bath NorCal home typically costs $8,000-$15,000. Larger homes, two-story layouts, or homes with finished basements cost more due to additional access challenges. The price includes all wire, devices, breakers, and labor.

How do I know if my house needs rewiring?+

Rewiring is needed if your home has knob-and-tube wiring (pre-1950), cloth-covered Romex (1950s-60s), aluminum branch circuits (1965-1975), or a Federal Pacific/Zinsco panel. Other signs include flickering lights, warm outlets, and frequent breaker trips.

Will rewiring damage my walls?+

Our electricians minimize wall damage by routing wire through attics, crawl spaces, and inside wall cavities. Strategic access holes (typically 4x4 inches) are cut and patched with drywall compound. Expect 10-20 access holes in a typical rewire.

How long does a whole-house rewire take?+

Most single-story homes are completed in 3-5 days. Two-story homes take 5-7 days. You'll have power each evening — we prioritize keeping essential circuits live during the work.

Does insurance require rewiring for old wiring?+

Many insurance companies in NorCal will not insure or renew policies on homes with knob-and-tube wiring or Federal Pacific panels. Rewiring resolves the issue and can reduce your premium by 10-20%.
