Why Rewire?

Does Your Home Need Rewiring in Los Angeles?

"According to Amy, founder of AMY Electric and Licensed C-10 electrical contractor with 15+ years of experience: 'I've opened up panels in 1920s LA bungalows with original wiring that's literally crumbling. That's not something to wait on — if you have knob-and-tube or cloth-wrapped wiring, it's not a matter of if it will fail, but when. NFPA data shows that 30% of home electrical fires originate in wiring older than 40 years.'"

Many Los Angeles homes built before 1970 still operate on outdated electrical systems never designed for modern loads. If you're experiencing any of these warning signs, your home may need a full or partial rewire.

🔌

Knob-and-Tube Wiring

Found in pre-1940s LA homes. Uninsulated, easily damaged, and a fire hazard — most insurance companies won't insure homes with active knob-and-tube wiring.

🔧

Aluminum Branch Wiring

Common in 1960s–70s homes. Aluminum connections expand and contract differently than copper, leading to loose connections and fire risk. We remediate with approved connectors.

💡

Cloth-Wrapped Wiring

Rubber and cloth insulation dries out and cracks over time, leaving bare wire exposed. A common fire risk in 1940s–60s LA homes.

🔄

2-Prong (Ungrounded) Outlets

Unsafe for modern electronics. Rewiring brings grounded 3-prong outlets to every room, meeting current NEC and LA code requirements.

⚡

Frequent Breaker Trips

An outdated system can't handle modern loads (kitchen appliances, home office, entertainment, EV charging). Rewiring eliminates persistent tripping.

🏗️

Major Renovation

Opening up walls for a kitchen or bath remodel is the ideal time to rewire. We coordinate with your GC for maximum efficiency.

The Rewiring Process

How Does the Whole-Home Rewiring Process Work in Los Angeles?

Free Consultation & Scope

We inspect your home's existing wiring, panel, and outlets. We identify which circuits need replacement and provide a detailed written estimate.

Permit & Planning

We file for the electrical permit with LADBS. For a full rewire, we coordinate the inspection phases: rough-in, trim, and final sign-off.

Rough-In Wiring

New cables pulled through walls (fishing from attic or crawlspace). Old wiring disconnected and removed where accessible. Boxes installed for every outlet, switch, and fixture.

Rough-In Inspection

LADBS inspector reviews the wiring before walls are closed. This ensures everything meets code before drywall goes up.

Trim & Finish

Outlets, switches, and fixtures installed and wired. Panel connections completed. Everything tested circuit by circuit.

Final Inspection & Sign-Off

Final LADBS inspection, permit closed, and your home's electrical system is safe for decades to come.

FAQ

Rewiring FAQ

How do I know if my LA home needs rewiring? ▾

There are several clear signs that your Los Angeles home may need partial or complete rewiring. The most obvious indicators include: frequent breaker tripping or blown fuses, flickering or dimming lights that affect multiple rooms, outlets that are warm to the touch or discolored from heat, a persistent burning smell near outlets or switches, outlets that work intermittently or only when you jiggle the plug, visible signs of wiring deterioration such as frayed fabric insulation (common in pre-1950s knob-and-tube wiring), or a panel that has no remaining empty slots and uses older, obsolete breakers like Federal Pacific or Zinsco. If your home was built before 1970, the original wiring may have cloth or rubber insulation that becomes brittle and cracks with age, creating short circuit and fire risks — this was common wiring practice through the 1960s. Los Angeles homes with knob-and-tube wiring, early aluminum wiring (1965-1973), or cloth-insulated wiring are all strong candidates for a professional rewiring evaluation. We offer free on-site inspections to assess your home's wiring condition.

Can I stay in my home during a rewire? ▾

Yes — in most cases, you can remain in your home during a whole-home rewiring project, though there will be periods without power to portions of the house as work progresses on different sections. We plan the rewiring work in phases — typically one room or one circuit at a time — to minimize disruption and keep essential circuits powered throughout most of the project. We coordinate with you to identify the circuits that must remain live at all times, such as refrigeration, medical equipment, home office equipment, and critical lighting for safety. Most whole-home rewiring projects for typical Los Angeles homes take 5 to 10 days to complete, and we schedule the work so that only the rooms being actively rewired are without power at any given time. There will be some dust and drywall patching involved, as we need to access wiring that runs inside walls, but we take care to minimize damage and seal off work areas from the rest of the home. We recommend adding whole-home rewiring to a home renovation project for maximum efficiency.

Do I need to cut into my walls for rewiring? ▾

In most cases, yes — some wall and ceiling access is required to run new wiring through your home. However, the extent of wall cutting depends on your home's construction type and whether you have accessible attic or crawlspace above and below the living areas. For single-story homes with an accessible attic, we can run new wiring from above and minimize wall access to only the vertical sections where outlets and switches are located. For homes with basements or crawlspaces, we can run wiring from below. For homes on concrete slabs and multi-story homes with finished ceilings between floors, more wall and ceiling access is typically required. We keep wall damage to a minimum by using techniques like fishing wires through existing wall cavities, using existing conduit paths where available, and carefully cutting only the access holes needed at each outlet and switch location. We patch all access holes as part of the rewiring project, leaving your walls ready for painting.

Does insurance cover knob-and-tube wiring? ▾

Many insurance companies in Los Angeles will not write new policies or renew existing policies for homes with active knob-and-tube wiring (K&T), as it is considered a high-risk electrical system by the insurance industry. Knob-and-tube wiring lacks a ground wire, uses insulation that becomes brittle and cracks with age, was not designed for modern electrical loads, and is often found in deteriorated condition in older homes. Some insurers may require proof that the knob-and-tube wiring is in good condition and has been inspected by a licensed electrician, but most will require it to be replaced entirely for new policy issuance. Even if your current insurer has not made an issue of your knob-and-tube wiring, any future claim related to an electrical problem could be denied if the insurer determines the knob-and-tube wiring contributed to the loss. The safest and most cost-effective approach is to have knob-and-tube wiring replaced as part of a whole-home rewiring project, which also brings your home's electrical system up to modern safety standards.

How long does a full home rewire take? ▾

A complete whole-home rewiring project for a typical single-family Los Angeles home (1,500 to 2,500 square feet) takes 5 to 10 working days, depending on the size and complexity of the home, the accessibility of the wiring paths, and whether the home will be occupied during the work. Smaller homes under 1,200 square feet with good attic and crawlspace access can often be completed in 3 to 5 days. Larger homes over 3,000 square feet or homes with complex construction (multi-story, finished basements, concrete slab foundations, or historic construction) typically take 7 to 14 days. The timeline also depends on the extent of wall patching required afterward and whether patching is included in the project scope. We provide a detailed timeline during your free on-site evaluation based on your home's specific configuration and the scope of the rewiring project. Most homeowners find the temporary inconvenience well worth the long-term safety and reliability benefits.

How much does whole-home rewiring cost in Los Angeles? ▾

Whole-home rewiring in Los Angeles typically costs $8,000 to $18,000 for a standard single-family home, depending on home size, number of circuits, accessibility (attic vs crawlspace vs slab), and finish restoration. Smaller homes with open attic access start lower; larger or multi-story homes with finished ceilings run higher. Partial rewires targeting specific circuits (knob-and-tube removal, aluminum remediation) start lower and can be phased. Every job gets a written itemized estimate after a free on-site evaluation — call (818) 302-5614.

Do I need a permit to rewire my home in Los Angeles? ▾

Yes — whole-home rewiring in Los Angeles requires an electrical permit from LADBS, with inspections at rough-in, trim, and final sign-off. We handle the entire process: filing the permit, coordinating each inspection phase, scheduling around your occupancy, and closing the permit at final. Unpermitted rewiring can void insurance coverage and create sale complications, so every rewire we do is fully permitted and documented.
