Why knob-and-tube wiring replacement comes up in Pensacola
North Hill, Pensacola's large historic district, holds homes built during the lumber boom of the late 1800s and early 1900s, and some still have knob-and-tube wiring in attics and crawl spaces. Humidity and termites are hard on old insulation, and Florida insurers often decline homes with active knob-and-tube. Raised foundations give the electrician a crawl space route for new cable.
North Hill's preservation board reviews visible exterior changes. Permits come from the City of Pensacola's inspection services, and FPL coordinates any service change. Ask for the work to be documented for insurers.

Knob-and-Tube Wiring Replacement in Pensacola: questions
Do I need a permit for knob-and-tube wiring replacement in Pensacola?
Usually, yes. Inside city limits, electrical permits come from the City of Pensacola's inspection services; unincorporated Escambia County has its own. Florida licenses electrical contractors through the Department of Business and Professional Regulation. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Pensacola?
If the work affects the meter or service, the electrician coordinates with Florida Power & Light (FPL, formerly Gulf Power), 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.
