Old, active knob-and-tube electrical wiring was discovered in this attic that had been unprofessionally spliced with modern electrical wiring and was in direct contact with framing elements in the attic, clear safety issues. My client was under the impression that all wiring in this home had been updated; truth be told, it simply was not. I recommended further evaluation and repair by a qualified electrician. If you have knob-and-tube wiring, consider upgrading to modern wiring. At a minimum, don’t splice into it and keep it clear and free from contacting anything as it can overheat. Do not insulate attics or crawl spaces that have knob-and-tube wiring. This was discovered at a recent home inspection in Oak Harbor on Whidbey Island.
