Knob and Tube Wiring Replacement Services

Knob and tube (K&T) wiring was the standard electrical wiring method used in homes built from the 1880s through the 1940s. While some older Cape Coral and Fort Myers area homes may still have remnants of this outdated wiring system, it presents significant safety concerns by modern standards. Project Pros connects homeowners with experienced electricians who specialize in complete knob and tube wiring replacement, bringing your home up to current electrical codes and eliminating fire risks.

Why Knob and Tube Wiring Is Dangerous

Knob and tube wiring was designed for the electrical loads of a century ago, typically just a few lights and a radio per room. Modern homes draw far more power for air conditioning, appliances, computers, and entertainment systems. K&T wiring lacks a ground conductor, making it incompatible with three-prong outlets and offering no protection against electrical shock. The rubber insulation on K&T wiring degrades over time, becoming brittle and cracking to expose bare copper conductors. When covered with blown-in insulation, as happened in many home renovations, K&T wiring can overheat and ignite the surrounding material.

The Replacement Process

Complete knob and tube replacement involves running new NM-B (Romex) cable throughout the affected areas of your home, installing new outlets and switches with grounding, connecting all new circuits to your electrical panel with proper breaker protection, and removing or abandoning the old K&T wiring. In some cases, a panel upgrade may be necessary to accommodate the additional circuits required by modern electrical code. Our electricians minimize wall and ceiling damage by using existing pathways and strategic access points.

Insurance and Real Estate Implications

Many insurance companies in Florida will not insure homes with active knob and tube wiring, or they charge significantly higher premiums. If you are buying or selling a home with K&T wiring, this can be a major obstacle. Replacing knob and tube wiring removes this barrier, often resulting in lower insurance premiums and increased property value. It also satisfies home inspection requirements and gives buyers confidence in the safety of the electrical system.
