Do Not Postpone a Complete Knob and Tube Wiring Removal

Windward Electric is a certified electrical contractor dedicated to helping homeowners increase the safety of their houses. We can provide knob and tube wiring removal and a full electrical upgrade.

While almost obsolete today, knob and tube wiring, also  known as K&T wiring, still shows up in homes built from about 1880 to 1950. Wires run around and through ceramic knobs and tubes. Professional electrical service contractors, insurance companies, and realtors typically recommend that owners of older houses undergo knob and tube wiring removal and have their home completely rewired.

K&T wiring was developed during a time when homeowners had few electrical appliances, and there was still little knowledge of the dangers of electrical surges. You will recognize the K&T wiring by a porcelain knob installed on the outer wall of the house. The electricity is transported throughout the house by wiring encased in a tube. This system was popular because it was cheap to install. But, at the present, it is a major liability for the safety of your home. While knob and tube wiring was not inherently dangerous when first constructed, today safety concerns arise from the system's age, proximity to housing insulation, and any incorrect modifications made over time. Therefore, you’ll want to take care of knob and tube wiring replacement, as soon as possible.

The Most Significant Knob and Tube Wiring Dangers

The many knob and tube wiring dangers you and your family are exposed to make this effort to replace them necessary. Here are the key problems with this electrical wiring system:

  • It does not have a ground wire to dissipate overloaded circuits into the ground
  • Insulation around the tube will cause it to overheat, as it was designed to remain exposed to the air 
  • The tube is made of natural rubber or asphalt-soaked cotton and suffers significant wear and tear over time
  • The knob and tube wiring network is not adequate for modern electricity consumption.

As you may imagine, knob and tube wiring removal and a full electrical wiring upgrade typically represents a significant home improvement project. The cost to update knob and tube wiring ranges in the thousands of dollars and having your electrical system replaced may alter your daily routine for a few weeks, but the investment now will ensure your safety for years to come. 

Practical Advice for Knob and Tube Wiring Replacement

Since it is a major upgrade for your home, knob and tube wiring removal should be scheduled as part of a larger-scale home remodeling project if possible. Even the hidden parts of the walls will become exposed as insulation is stripped down for replacement.

Removal is recommended when installing attic insulation, selling, buying or remodeling. In fact, many insulation contractors won't insulate your home until any existing knob and tube (K&T) wiring is removed. 

If you live in an older home that has undergone some modernization, you may still have knob and tube wiring in less accessible areas, such as the attic, crawl rooms, and under-the-stair cupboards. A certified electrician will identify all these spots and recommend the best approach for knob and tube wiring replacement.
