Why knob-and-tube wiring replacement comes up in Tulsa
Maple Ridge, Brady Heights, Swan Lake and Riverside hold many of Tulsa's homes from the oil boom of the 1910s and 1920s, and knob-and-tube wiring is still found in some of them, sometimes extended during later renovations. Large Maple Ridge homes may need floor-by-floor work to protect woodwork. Crawl spaces, basements and attics give the electrician routes for new cable.
Several of these neighborhoods are historic preservation districts. Permits come from the city's Development Services, and PSO coordinates any service change. Ask for the rewire documented for insurers.

Knob-and-Tube Wiring Replacement in Tulsa: questions
Do I need a permit for knob-and-tube wiring replacement in Tulsa?
Usually, yes. Electrical permits in Tulsa come from the city's Development Services; Broken Arrow and other suburbs issue their own. Oklahoma licenses electricians through the Construction Industries Board. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Tulsa?
If the work affects the meter or service, the electrician coordinates with Public Service Company of Oklahoma (PSO), 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.
