Knob and Tube wiring was the original method of wiring homes built up to around 1930. Although it was a sufficient means to wire a home, that doesn’t mean that 100 years later it is still in proper working condition. The rubber insulation can turn brittle and break leaving exposed wiring in your walls, basement, or attic space. Covering K&T wiring with insulation can cause the wires to overheat and possibly melt as well. Homes originally wired in K&T lacked the electrical demand that we need to run a typical home today. If you live in a home with K&T wiring, please call for an electrical assessment.
