Types of Wiring That Need Replacement
Knob-and-Tube Wiring
Found in homes built before 1940. Uses individual hot and neutral conductors through ceramic knobs. No ground wire. Fire hazard. Many insurers won't cover homes with active K&T wiring.
Aluminum Wiring
Used in homes built 1965–1973. Prone to loose connections at outlets and switches, causing overheating and fire risk. Requires special COPALUM or AlumiConn connectors at every connection point.
Ungrounded Romex (2-Wire)
Found in homes built 1940–1960. Has insulated conductors but no equipment ground. Limits outlet types and creates safety hazards for modern electronics and appliances.
Undersized Wiring
Older homes with 14-gauge or undersized wiring on 20A circuits. Can't handle modern electrical loads, causing overheating and fire risk.
What to Expect During Whole-Home Rewiring
We inspect your entire electrical system, document existing wiring types, and develop a rewiring plan with you.
Whole-home rewiring requires an LADBS permit. We handle all paperwork and schedule the inspection timeline.
We access walls through attic, crawl space, or small openings in drywall. Minimal patching required when done by experienced electricians.
All circuits are run with modern 12-gauge or 10-gauge Romex with proper grounding. New outlets, switches, and junction boxes installed.
Old fuse boxes or undersized panels are replaced with modern 200A breaker panels during the rewiring process.
Every circuit is tested for proper grounding, GFCI/AFCI protection, and load capacity. City inspector verifies code compliance.
Signs Your Home Needs Rewiring
Burning Smell
A burning or hot plastic smell from outlets, switches, or your panel is an immediate safety concern. Stop using the circuit and call an electrician.
Flickering Lights
Lights that flicker or dim when appliances cycle on indicate inadequate wiring capacity or loose connections.
Two-Prong Outlets
Ungrounded two-prong outlets throughout the home signal outdated wiring that can't support modern electrical needs.
Frequent Breaker Trips
If breakers trip regularly under normal household loads, your wiring may be undersized or deteriorated.
Insurance Requirements
Many homeowner insurance companies require rewiring of homes with knob-and-tube or aluminum wiring as a condition of coverage.
Home Purchase
If you're buying a home with outdated wiring, rewiring before moving in avoids costly surprises and ensures code compliance.
How Long Does Rewiring Take?
| Home Size | Typical Timeline |
|---|---|
| Under 1,000 sq ft | 3–5 days |
| 1,000 – 1,500 sq ft | 5–7 days |
| 1,500 – 2,000 sq ft | 7–10 days |
| 2,000+ sq ft | 10–14 days |
You will likely need to vacate for 2–5 days during the most invasive phase. Your electrician will provide a specific timeline for your home.
