Why you should replace your home’s knob & tube electrical wiring

• It is not safe.

• Older houses, particularly those constructed prior to the 1950’s, used “knob and tube” wiring (also called K & T) and are considered electrical safety risks today.

• You will have trouble getting home insurance, unless you can produce a licensed electrician’s certificate of inspection confirming that all knob and tube has been replaced.

• Your property’s market value will be downgraded.

• You cannot insulate your home with knob and tube wiring.

Why is knob & tube wiring considered a safety hazard?

• Lack of a grounding conductor.

• Potential for shock, electrocution, sparks, fire, circuits blowing/over-heating, and damage to equipment and switches.

• Brittle and disintegrating insulation.

• Adding onto to this older system with modern wiring only increases these dangers.
