Knob and tube wiring was once the gold standard for electrical systems, but over time it has proven to be outdated and dangerous. As a homeowner, it's important to understand the risks of knob and tube wiring and why it's best to fully replace it.

A Brief History of Knob and Tube Wiring

Knob and tube wiring was commonly installed in homes built prior to 1930. It features insulated wires that are run through ceramic knobs attached to framing studs, and through porcelain tubes through walls and ceilings.

At the time, knob and tube was an excellent system - the thick rubber insulation minimized fire risk. It was perfectly adequate for the limited number of electrical devices found in early 20th century homes.

By the 1950s and 60s however, knob and tube began to pose risks as electricity needs increased. Yet many homes today still rely on antiquated and dangerous knob and tube systems.

Why Knob and Tube Wiring Must Be Fully Replaced

Is it Worth the Investment?

Consider that a wiring fire can cost tens or hundreds of thousands in repairs. And remember, money can’t replace lost memories or ancestral possessions damaged in a fire.

Finally, the security of knowing your home's electrical system is completely modern and safe is priceless.
