Can old knob-and-tube components remain after rewiring?
Yes. Visible old components can remain after circuits are abandoned, so appearance alone does not tell you whether they are active.
Can I insulate around knob-and-tube wiring?
Rhode Island's Weatherization Assistance Program guidance places restrictions on insulating walls and attics where active knob-and-tube is present. Private work still needs a property-specific evaluation under applicable requirements.
Do I need a permit in Providence?
Providence states that its Electrical Division oversees electrical alterations, repairs and replacement through permits and inspections required by law. The exact permit requirements depend on the project.
Can you quote removal from a photo?
Photos can help identify visible conditions, but a reliable project price may require determining what wiring is active and how extensive the affected circuits are.
