Why knob-and-tube wiring replacement comes up in West Palm Beach
Some of West Palm Beach's 1920s homes in Northwood, Grandview Heights and Flamingo Park still have knob-and-tube wiring from the Florida land boom, hidden in attics and walls. Florida insurers often decline homes with active knob-and-tube. Thick masonry walls in Mediterranean Revival homes make routing new cable harder, so electricians use attics, crawl spaces and interior walls.
The historic districts review exterior changes. Permits come from the City of West Palm Beach's development services, and FPL coordinates any service change. Ask for the work to be documented for insurers, and for grounded outlets to be added in every room.

Knob-and-Tube Wiring Replacement in West Palm Beach: questions
Do I need a permit for knob-and-tube wiring replacement in West Palm Beach?
Usually, yes. Electrical permits inside city limits come from the City of West Palm Beach's development services; Palm Beach County handles unincorporated areas. Florida licenses electrical contractors through the Electrical Contractors' Licensing Board under DBPR. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in West Palm Beach?
If the work affects the meter or service, the electrician coordinates with Florida Power & Light (FPL), which owns the meter and service drop.
Is knob-and-tube wiring illegal?
Existing knob-and-tube is generally not illegal, but it cannot be extended, and many insurers and lenders treat it as a reason to replace.
Can knob-and-tube be insulated over?
It is not recommended, and many codes and insulation programs prohibit it, because the wiring relies on open air to cool.
How do I know if mine is still live?
An electrician can test it. Many homes have a mix of active and abandoned knob-and-tube.
How long does replacement take?
From a few days for a small home with good access to a few weeks for larger plaster-walled homes.
