Aging cloth-insulated wiring, ungrounded outlets, and outdated circuits are hidden fire hazards lurking in many Southern California homes. Whole-house rewiring eliminates these risks while preparing your home for modern demands like rooftop solar, EV chargers, and smart appliances. The cost of electrical rewiring in Los Angeles varies based on home size and wall accessibility. In this updated 2025 guide, Farashi Electric outlines the key warning signs, provides real-world cost insights, and offers a step-by-step plan to help you upgrade your home’s wiring safely and efficiently.
Audio transcript & key points
Wiring and rewiring ensures your home’s electrical system is safe, reliable, and ready for modern loads like HVAC upgrades, remodels, and new appliances. Common signs you may need rewiring include frequent breaker trips, flickering or dimming lights, warm outlets or switches, buzzing sounds, burning smells, outlets that stop working, or older wiring that no longer meets today’s safety expectations. A professional rewiring job starts with an on-site assessment and planning, then installs code-compliant wiring and properly sized circuits, confirms grounding, and fully tests the system before finishing. When needed, work can be staged to reduce disruption. Farashi Electric provides wiring and rewiring in Los Angeles with safety-first, neat workmanship and clear communication. Call (267) 248-5496 for a free estimate, and share photos of your electrical panel and the areas you’re upgrading for a quick pre-assessment.

For home rewiring in Los Angeles, CA, Farashi Electric helps homeowners decide whether they need targeted circuit repairs, partial rewiring, or whole-home rewiring. Our residential electrical rewiring services include planning safe circuit layouts, upgrading grounding and protection, reducing hidden fire risks, and preparing the home for modern loads like HVAC, EV charging, kitchen appliances, and smart devices.
If you’re already seeing flickering lights, hot outlets, or mystery breaker trips, our Electrical Problems in House – Los Angeles safety guide takes a closer look at those symptoms, why they happen, and when it’s time to move from “watching it” to planning a full or partial rewire.
| Symptom | What It Means |
| Frequent breaker trips when the AC and microwave run together | Circuits overloaded |
| Two-prong (ungrounded) outlets | No safe path for fault current |
| Warm or sizzling wall plates | Loose connections causing arcing |
| Flickering lights during appliance start-up | Voltage drop from undersized conductors |
| Cloth or knob-and-tube wiring visible in attic | Insulation at end of service life |
| Aluminum wiring spliced with copper | High-resistance joints |
| No GFCI/AFCI protection in kitchens & bedrooms | Code non-compliance |
| Burnt smell near outlets | Insulation breakdown |
| Outlets spark when you plug in devices | Internal arcing |
| You’re planning a major remodel or electrical panel upgrade in Los Angeles | Best time to run new cable |
Safety tip: If your home still uses 60-amp service, combine rewiring with a panel upgrade for maximum value.
Key Cost Drivers
- 1. Wall Access – Open-stud remodel vs. finished plaster can double labor. If you’re hoping to keep drywall damage minimal, our guide on how to rewire a house without opening the walls shows the “surgical” methods we use in Los Angeles homes to fish new cables with postcard-sized openings instead of demo lines.
- Service Upgrade Required? – Adding a 200-amp panel adds.
- Low-Voltage Wiring Bundles
- Permit & Inspection
- Finishes – Patching lath-and-plaster walls is labor-intensive.
Our Rewiring Process (Clean, Documented, Inspection-Ready)
- Assessment & Load Check – Map circuits, evaluate panel capacity, identify safety/code gaps.
- Permit & Planning – Scope, circuit map, device counts, arc-fault/GFCI strategy, and schedule.
- Rough-In – New homeruns, AFCI/GFCI protection, grounding/bonding corrections, box sizing, and labeling.
- 4. Device & Trim – TR outlets/switches, updated plates, neat panel schedules; torque to spec. If you’re curious what safe, code-clean fixture work looks like at the room level, our How to Wire a Light guide walks through a typical light-circuit upgrade with the same safety rules we use on full rewires.
- Testing – Polarity, continuity, GFCI/AFCI trip-tests, insulation checks, and load verification.
- Inspection & Final – AHJ walkthrough; deliver photo log + permit close-out.

Timelines & Pricing
Timelines & Pricing (Scope-Dependent)
Small room-by-room rewiring often completes in a few days; whole-home projects vary by square footage, access, and finish work. Final pricing depends on device counts, AFCI/GFCI, panel capacity upgrades, and patch/paint scope. We provide a written, permit-ready estimate after assessment.

Choosing the Right Materials & Add-Ons
Copper vs. Aluminum
We commonly recommend copper branch-circuit wiring for residential rewiring because it is durable, familiar to inspectors,
and suitable for modern household loads when sized correctly.
Most rewires also refresh worn-out receptacles and add new ones where you actually need them. If you’d like to understand what goes into safe outlet terminations, spacing, and GFCI/AFCI protection, our electrical outlet wiring in Los Angeles guide breaks it down step by step.
Aluminum & Knob-and-Tube: What We Do
We evaluate aluminum branch circuits for heat-related failures and use listed remediation (e.g., AlumiConn/COPALUM) or full rewiring as appropriate. For knob-and-tube, we replace brittle runs, add grounding, and bring outlets to modern safety (AFCI/GFCI where required), keeping finishes neat.
Code & Safety Essentials
- AFCI & GFCI: Bedrooms/living areas commonly require AFCI; kitchens, bathrooms, garages, outdoor and laundry areas need GFCI (local adoption applies).
- Tamper-Resistant Outlets: Use TR receptacles in dwelling areas for child safety.
- Grounding & Bonding: Correct equipment grounding and bonding (water/gas, metal raceways) are verified and upgraded where needed.
- Labeling & Torque: Breakers/neutral/ground bars are labeled, and all terminations are torqued to manufacturer spec.
- Box Fill & Cable Protection: Boxes sized per box-fill rules; cables protected at entries and along framing.
Want a bigger-picture look at how all this wiring work ties into whole-home protection? Our electrical home safety in Los Angeles guide walks through what a proper safety inspection covers, DIY pre-checks you can do safely, and how rewiring fits into a long-term plan to reduce risk—not just pass inspection once.
Permits & Local Rules
In the City of Los Angeles (LADBS) and LA County, electrical work typically requires a permit and final inspection. Straightforward residential rewiring often goes through express/online permitting, while larger scope (service changes, multi-unit, structural impacts) may need plan review. We confirm your Authority Having Jurisdiction (AHJ), pull the permit, and schedule inspection before energizing.
Share photos of your panel, sample outlets, attic wiring, or problem areas, and Farashi Electric will help you decide
whether you need targeted rewiring, partial rewiring, or a full-home rewire.
