What Is Whole-Home Rewiring?
Whole-home rewiring is the process of replacing all electrical wiring, devices, and often the service panel in a home. It's typically required when a home's electrical system is outdated, unsafe, or unable to support modern electrical demands.
Common in Older LA Homes
Many LA homes built before 1970 have outdated wiring like knob-and-tube or aluminum branch circuits that pose safety risks.
Modern Electrical Demands
Today's homes use far more electricity than homes built even 30 years ago. EV chargers, AC units, and home offices strain old systems.
Fire Safety
Old wiring is a leading cause of residential fires. Rewiring brings your home up to current California Electrical Code.
Home Value
Updated electrical is a major selling point. Buyers and insurance companies favor homes with modern, code-compliant wiring.
6 Signs Your LA Home Needs Rewiring
Knob-and-Tube Wiring
If your home was built before 1950 and has never been fully rewired, you likely have knob-and-tube wiring. This is ungrounded and often unsafe by modern standards.
Aluminum Branch Wiring
Homes built 1965–1973 may have aluminum branch circuit wiring, which is now known to pose fire risks at connections. Special connectors and treatments are required.
Frequent Tripped Breakers
If your breakers trip regularly or fuses blow, your electrical system is overloaded. This is common in older homes with modern electrical demands.
Flickering or Dimming Lights
Persistent flickering or dimming when appliances turn on indicates wiring issues, undersized circuits, or loose connections.
Burning Smell or Scorched Outlets
Any burning smell, warm outlets, or scorch marks around outlets are serious warning signs requiring immediate electrician inspection.
Two-Prong Outlets (No Ground)
If your home still has ungrounded two-prong outlets, your wiring is outdated. Modern code requires grounded three-prong outlets throughout.
What to Expect During Whole-Home Rewiring
Licensed electrician inspects your home's wiring, panel, devices, and grounding. You'll receive a detailed report and scope of work.
Permits are pulled from LADBS. We coordinate utility shutoffs and plan the rewiring sequence to minimize disruption.
Walls may need to be opened to access wiring. We work room-by-room and can coordinate with drywall and paint contractors.
New wires, boxes, and circuits are installed. New circuits are added for high-demand areas like kitchens, EV charging, and home offices.
LADBS inspects the rough-in wiring before walls are closed. We schedule and attend this inspection.
Outlets, switches, light fixtures, and cover plates are installed once walls are closed and finished.
LADBS performs final inspection. We close out permits and provide documentation of the completed work.
