  • In homes dating back to the early 1900s up to the 1950s, knob and tube wiring was frequently used as the primary electrical setup. This approach utilizes ceramic knobs to secure wires and tubes, protecting them as they go through the home’s framework. With single-insulated wires for both hot and neutral lines, this system keeps them spaced apart rather than bundled together.

  • While this wiring method was groundbreaking at its inception, it lacks many critical safety features expected in modern electrical systems. Modern lifestyles place greater strain on electrical systems, making knob and tube wiring an outdated choice for homes with numerous electronics and appliances.

  • A significant concern with knob and tube systems is their lack of grounding, which greatly limits their compliance with contemporary safety standards. As the system continues to age, its insulation can deteriorate, raising the risk of electrical faults, shocks, or even catastrophic fires. Therefore, upgrading to modern wiring is essential for ensuring safety and efficiency in any home.

Why Replace Knob and Tube Wiring?

Aging electrical systems can pose significant risks to homeowners. Since knob and tube systems are not grounded, they cannot channel excess electricity away from appliances or fixtures, increasing the risk of shock or fire. A lack of grounding in older wiring setups can make homes more vulnerable to dangerous electrical faults.

Another issue is that insulation used in these systems becomes brittle with age, leading to exposure of bare wires. Many insurance companies also won't cover homes with knob and tube systems due to the increased fire hazard.

Common signs that replacement is needed include flickering lights, frequent breaker trips, discolored outlets, or burning odors near outlets and switches. If you’re noticing these symptoms, your wiring may no longer be safe.

  • Your knob and tube rewiring project will begin with a thorough inspection by one of our electricians. Our professionals assess the current system, identify areas of risk, and develop a comprehensive replacement plan. The existing wiring is then carefully removed, and modern, grounded wiring is installed in its place.

    Throughout the installation, we take care to follow local code requirements to ensure long-term safety and compliance. Once the new system is installed, we test all circuits to confirm proper function and safe operation.

    This type of replacement helps prevent electrical hazards, improves performance, and provides the capacity needed for modern appliances and electronics.
