Why knob-and-tube wiring replacement comes up in Warwick
Pawtuxet Village and the older parts of Apponaug and Warwick Neck have homes from the late 1800s and early 1900s, and some still carry knob-and-tube wiring. Former summer cottages converted to year-round living often had wiring added a room at a time. Insulating over live knob-and-tube is not recommended, which matters in a coastal climate with cold winters.
Basements, crawl spaces and attics give the electrician routes for new cable. Permits come from the City of Warwick's building department, and Rhode Island Energy coordinates service work.

Knob-and-Tube Wiring Replacement in Warwick: questions
Do I need a permit for knob-and-tube wiring replacement in Warwick?
Usually, yes. Electrical permits come from the City of Warwick's building department. Rhode Island licenses electricians through the Board of Examiners of Electricians at the Department of Labor and Training. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Warwick?
If the work affects the meter or service, the electrician coordinates with Rhode Island Energy, 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.
