Reason #1: Fire Prevention
Knob & Tube's 100-year old  insulation has deteriorated over time. It lacks a grounding conductor and was never designed for modern electrical loads, increasing the risk of overheating and electrical fires.

Many insurance carriers either refuse to insure homes with active Knob & Tube wiring or charge significantly higher premiums. Some require full replacement before issuing or renewing a policy.
Inability to Insulate Your Home
Knob & Tube wiring relies on open air to dissipate heat. Modern insulation placed around it can trap heat and create unsafe conditions, limiting energy-efficiency by .
Reduced Home Resale Value
Buyers and home inspectors often flag Knob & Tube as a major concern. Its presence can delay sales, reduce offers, or require costly credits at closing.
‍Limited Electrical Capacity
Knob & Tube systems built in the early 1900's were not designed for today’s appliances, electronics, and EV chargers. Homes with K&T experience overloaded circuits and inadequate power.
