If your home or property was built before 1950, it may contain knob-and-tube wiring, an outdated electrical system never designed to handle the demands of modern electrical appliances, technology and home renovations.

Our licensed, professional electricians can quickly assess and repair your electrical issues to ensure your home is safe, code-compliant and will maintain its market value. 

Knob-n-Tube wiring is easy to spot. Porcelain knobs support the wires and ceramic tubes protect the wiring through the wooden framing. 

Knob-n-tube wiring, an electrical system installed primarily between the 1880s and 1940s. In some cases, even into the 1950s. While innovative for its time, knob-and-tube wiring is now considered outdated and potentially hazardous, especially when used in modern homes with significantly higher electrical demands.

Signs your home wiring, electrical system is outdated, unsafe and potentially hazardous.

Age, DiY Modifications, Modern Electrical Demands Matter

Knob-n-tube wiring was designed for the electrical demands of another era. Modern homes typically have substantially more electrical equipment, appliances, electronics and dedicated circuits.

Potential concerns with an older wiring system can include:

• Deteriorated wire insulation
• Improper modifications, extensions
• Lack of grounding on older circuits
• Overloaded circuits
• Inadequate electrical capacity
• Previous DiY electrical work
• Renovations completed without updating underlying wiring

Simply having knob-n-tube wiring alone does not tell you everything about the condition or safety of an electrical system.
