Knob and Tube Rewiring

Many older homes—especially those built before the 1950s—still rely on knob and tube wiring, one of the earliest types of electrical systems. While it was innovative in its time, knob and tube wiring cannot safely handle the electrical demands of modern living and often poses significant safety risks.

Why Replace Knob and Tube Wiring?

  • Safety Risks – With age, insulation deteriorates, leaving wires exposed and prone to overheating or sparking.

  • Limited Capacity – These systems were never designed for today’s appliances, electronics, and HVAC systems.

  • Insurance Issues – Many insurers will not cover homes with active knob and tube wiring.

  • Code Compliance – Modern codes require grounded, higher-capacity wiring for safe operation.

Benefits of a Rewire

Replacing knob and tube wiring with a modern system ensures your home is safe, efficient, and insurable. It also increases resale value, eliminates frequent electrical issues, and gives you the peace of mind that your electrical system can support today’s technology.

Professional Installation Matters

Knob and tube rewiring is a specialized job that requires a licensed electrician. The process involves carefully removing old wiring, upgrading circuits, and ensuring the system meets modern code requirements—all while minimizing disruption to your home.
