Rewiring a house in Goleta is one of the largest electrical projects a homeowner can undertake, and it is also one of the most misunderstood. Many homeowners assume their wiring is fine unless something is visibly wrong — a sparking outlet, a dead circuit, a breaker that trips. But wiring degrades over decades regardless of whether visible symptoms have appeared, and the homes most in need of rewiring are often the ones where the occupants have simply adapted to the limitations and warning signs rather than addressing them. This guide explains what rewiring a house actually involves, which Goleta properties are most likely to need it, what the process looks like, and what it costs — including how to minimize disruption to your daily life during the project.
What Does “Rewiring a House” Actually Mean?
A full house rewire means replacing all of the branch circuit wiring throughout the home — the wires that run from the electrical panel through walls and ceilings to every outlet, switch, and fixture. It does not typically include replacing the main service entrance cable (the wires from the meter to the panel) unless that is also found to be in poor condition, though those are often addressed at the same time.
A partial rewire addresses specific circuits or areas — a kitchen rewire to support modern appliance loads, a bedroom rewire to address aluminum wiring in that area, or a bathroom rewire to bring an old two-prong circuit up to GFCI code compliance. Partial rewires are significantly less expensive and disruptive than full rewires, and in many cases they address the most critical areas of concern while deferring lower-priority sections.
The wiring itself — the copper (or aluminum) conductors running through the walls — is what gets replaced. Outlets, switches, and fixtures are typically replaced simultaneously because the labor of accessing those locations is already part of the project. Wiring installation and wiring repair are core services Blue Moon Electrical performs throughout Goleta and the Santa Barbara area.
Which Goleta Homes Are Most Likely to Need Rewiring?
Age is the primary factor. Goleta’s housing stock includes a large number of homes built between 1945 and 1980, and different construction eras introduced different wiring issues:
- Homes built before 1960: May have knob-and-tube wiring — an early wiring method using individual conductors run through ceramic insulators. Knob-and-tube wiring has no ground conductor, no plastic sheathing, and was designed for much lower electrical loads than modern homes require. Many insurance carriers will not cover homes with active knob-and-tube wiring.
- Homes built 1965 to 1973: The aluminum wiring era. During this period, copper prices spiked and aluminum was substituted for branch circuit wiring. Aluminum wiring is more susceptible to oxidation, expands and contracts more with temperature changes, and requires specific connector types that were often not used in original installations. The CPSC has documented higher fire risk in homes with aluminum branch circuit wiring.
- Homes built through the 1980s: Wiring in good condition structurally but often undersized for modern loads, lacking AFCI protection, and missing the ground conductor in some areas. Outlets may be two-prong, lacking ground protection that modern equipment expects.
In addition to age, visible symptoms suggest rewiring may be warranted: outlets that feel warm to the touch, a persistent burning smell with no identifiable source, lights that flicker across multiple circuits, multiple outlets failing in a short period, or a property that has had repeated unexplained electrical fires or incidents.
“When I open a wall in one of these older Goleta homes and find cloth-insulated wiring, the insulation is brittle — it crumbles when you touch it. That wiring has been in place for 60 years and the insulation is at the end of its life. The wire itself may be fine, but the insulation protecting it is not.”

From our experience assessing properties across Goleta and the surrounding area
about 3 in 10 homes built before 1975 that we inspect have at least one wiring condition that warrants professional remediation — whether full rewire, aluminum wiring pigtailing, or targeted circuit replacement. Most homeowners are unaware of these conditions until an electrician opens a wall or panel and finds them.
The House Rewiring Process: What to Expect
A full house rewire is a multi-day project that requires some access to wall cavities. In finished homes without attic access, this may involve cutting small access holes in drywall at strategic locations to run new wire — a process that is less invasive than it sounds when done by experienced electricians using fish tape and flexible drill bits. Drywall patching after the electrical work is typically a separate trade (a drywall contractor or handyman), though some electrical companies offer this as part of their scope.
In homes with accessible attics, many wire runs can be made through the attic without any wall openings, significantly reducing the drywall repair component. In Goleta’s ranch-style and single-story homes, attic access makes rewiring substantially less disruptive.
The general sequence for a full house rewire:
- Assessment and planning: The electrician walks the property, assesses existing wiring condition, plans the new circuit layout, and identifies access strategy for each area.
- Permit application: A rewire always requires a permit. The scope is submitted to Santa Barbara County Building and Safety for review.
- Rough-in phase: Old wiring is removed (where accessible) and new wiring is run. New boxes are installed at each outlet, switch, and fixture location.
- Rough-in inspection: County inspector verifies wiring before walls are closed. This is a critical step — passing rough-in inspection before any drywall work begins.
- Finish phase: Outlets, switches, fixtures, and the new panel (if panel upgrade is included) are installed and connected.
- Final inspection: County inspector verifies completed installation meets all code requirements.
Cost of House Rewiring in Goleta
Rewiring costs vary significantly based on home size, accessibility, and the scope of work. General ranges for Goleta properties:
- Partial rewire (one to three circuits or one area): $800 to $3,000 depending on complexity and access difficulty.
- Aluminum wiring remediation (pigtailing all devices): $2,000 to $5,000 for a typical Goleta home, depending on the number of outlets, switches, and fixtures.
- Full house rewire, small home (under 1,200 sq ft): $5,000 to $9,000.
- Full house rewire, medium home (1,200 to 2,000 sq ft): $8,000 to $15,000.
- Full house rewire, large home (over 2,000 sq ft): $12,000 to $25,000 or more depending on access and configuration.
These ranges are for electrical work only and do not include drywall patching, which is a separate cost if access holes are required. An experienced electrician will describe the access strategy and drywall repair implications clearly in the estimate.
Aluminum Wiring: The Partial Rewire Alternative
For homes with aluminum branch circuit wiring, a full rewire is not always the first recommendation. The CPSC-approved remediation method is to install approved anti-oxidant compound at every connection point and replace all devices (outlets, switches) with co-alr rated equivalents — a process called pigtailing when copper pigtail connections are used at each device. This approach, done correctly throughout the entire home, addresses the primary hazard of aluminum wiring at a lower cost than full rewiring.
The limitation of pigtailing is that it addresses the connection hazards but does not change the fact that aluminum conductors are running through the walls. For homeowners planning to sell within the next five years, full rewiring is often preferable because buyers and their agents may be concerned about aluminum wiring regardless of whether it has been properly remediated.

Insurance and Real Estate Implications of Old Wiring
California homeowners and landlords with knob-and-tube or aluminum wiring face increasingly assertive insurance requirements. Several major carriers no longer write new policies for homes with active knob-and-tube wiring and are actively non-renewing existing policies when inspections reveal it. The insurance motivation for rewiring is real and growing.
In real estate transactions, wiring condition is a material disclosure item in California. A buyer’s home inspection that identifies knob-and-tube or aluminum wiring triggers negotiation — often a price reduction, a remediation credit, or in some cases a deal that falls through entirely. Homeowners who address wiring before listing are in a much stronger negotiating position than those who disclose it as an unresolved issue.
