What Is Whole-House Rewiring?
Whole-house rewiring is the process of replacing a home's outdated, ungrounded, or deteriorating electrical wiring with modern, code-compliant circuits — typically needed in homes still running on knob-and-tube, cloth-insulated, or aluminum branch wiring from decades past. Rather than treating each symptom separately, a full or partial rewire brings the entire system up to current California Electrical Code, properly grounded and sized for how the home is actually used today. J&J Electric performs whole-house and partial rewiring throughout Santa Rosa and Sonoma County under one C-10 license, #1078243, including older homes in Coffey Park and other post-Tubbs-Fire rebuild neighborhoods.
Our Process
Rewiring an occupied home takes real planning. Here's what happens after you call (707) 480-8331:
- You call or request a quote. Tell us what's going on — frequent breaker trips, two-prong outlets, knob-and-tube you found in the attic — and we'll ask what we need to understand the scope.
- We inspect what you actually have. We assess the wiring throughout the home before recommending full or partial rewiring, so we're not guessing at the scope.
- You get a written, itemized estimate. Labor, materials, and permit costs broken down clearly — no lump-sum guessing.
- We pull the permit. Filed under our own license, with the City of Santa Rosa or Sonoma County inspection scheduled by us.
- We do the work in stages where we can. Fishing new wire through existing cavities wherever possible, minimizing wall openings, and keeping power available where we can so the home stays livable.
- Final inspection and walkthrough. Every circuit is labeled, documented, and inspection-ready before we call the job done.
How Much Does Whole-House Rewiring Cost in Santa Rosa?
Whole-house rewiring is priced by scope rather than a flat rate, because the size of the home, how accessible the walls are, and how much of the electrical system needs replacing all move the number significantly. The main cost factors are square footage, wall and ceiling accessibility, whether the work can be phased, and how much of the existing wiring — knob-and-tube, cloth, or aluminum — needs to come out. We give you a written, itemized estimate after inspecting the actual home, so you know the real number before any work starts.
Whole-House vs. Partial Rewiring — Which Do You Need?
A whole-house rewire replaces the wiring throughout the entire home in one coordinated project — the right call when most of the system is outdated or a home inspection or insurance requirement flags widespread issues. Partial rewiring addresses specific problem areas or circuits — a kitchen with cloth wiring, a section of knob-and-tube in one wing — while leaving sound, modern wiring elsewhere untouched.
We'll give you an honest read after inspecting the home. Sometimes a full rewire genuinely is the safer, more cost-effective long-term choice; other times, tackling the worst circuits first and phasing the rest over time makes more sense for your budget and how disruptive you're willing to let the project be.
Whole-House Rewiring
What's Included — Whole-House Rewiring We Handle
Knob-and-Tube & Cloth Wiring Replacement
Deteriorating cloth insulation on old knob-and-tube wiring can expose bare wire, and it's a real, documented fire and shock risk in older Santa Rosa homes — we replace it with modern, grounded copper wiring throughout.
Aluminum Branch Wiring Remediation
Homes built in the 1960s and 70s sometimes carry aluminum branch wiring, which poses a genuine fire risk specifically at its connection points — we address this with proper remediation, not just a cosmetic fix.
Whole-Home Recircuiting to Modern Loads
EV chargers, induction ranges, and modern appliances draw more than older wiring was ever built for — we bring the whole system up to a capacity that matches how the home is actually used today.
Hazardous Panel Coordination
Outdated wiring and a hazardous panel brand like Federal Pacific Stab-Lok or Zinsco often show up in the same older home — if yours does, we can address both in one coordinated project. See our electrical panel upgrades page →
Grounding & Code Compliance
Proper grounding and bonding throughout the home isn't optional — it's the foundation every modern circuit, GFCI, and AFCI protection depends on, and we bring every run up to current California Electrical Code.

FAQ
Frequently Asked Questions
How much does whole-house rewiring cost?
Pricing depends on home size, wall accessibility, and how much of the existing wiring needs to be replaced. You get a written estimate before work begins.
How long does whole-house rewiring take?
Timelines vary by home size and scope; larger or less accessible projects naturally take longer.
Can I stay in my home during a rewire?
In most cases, yes. We phase the work in stages to keep power available where possible and minimize disruption throughout the project.
Is knob-and-tube wiring actually dangerous?
Yes — deteriorating cloth insulation on knob-and-tube wiring can expose bare wire, creating a genuine fire and shock risk, especially where it's been buried in insulation or spliced over the years.
Is aluminum wiring a fire risk?
Yes — aluminum branch wiring from the 1960s and 70s poses a documented fire risk specifically at its connection points, and it typically requires proper remediation, not just a cosmetic repair.
Do I need a whole-house rewire, or just a partial one?
It depends on how much of the existing wiring is outdated or unsafe. We'll give you an honest assessment after inspecting the home rather than defaulting to the bigger job.
Will rewiring my house help with my homeowners insurance?
Often, yes — many insurers offer discounts once a home's wiring is brought up to modern, code-compliant standards, and outdated wiring or a hazardous panel brand can sometimes affect coverage.
Do I need a permit for whole-house rewiring in Santa Rosa?
Yes — whole-house rewiring requires a permit from the City of Santa Rosa or Sonoma County, and we handle that under our own C-10 license.
