I'm renovating my 1970s house and discovered a lot of old knob-and-tube wiring. I'm worried about safety and insurance implications. Has anyone dealt with this? What should I prioritize?
Outdated Wiring Risks
Knob-and-tube is considered unsafe for modern loads. Replace it with NM‑B (Romex) or conduit. Most insurers require full replacement for coverage. Get a licensed electrician to inspect before you start any new circuits.
I swapped out the old wiring in my basement last year. Got a permit, had an inspection, and the insurer lowered my premium. Worth the effort!
