SumZero performs a detailed electrical assessment, safely removes outdated wiring, and installs modern grounded circuits that meet current safety codes. Clear communication ensures homeowners understand the upgrade process.

How do I know if my home has knob and tube wiring

Signs of knob and tube wiring include ceramic knobs in the attic or basement, two-prong outlets, or ungrounded circuits. A licensed electrician can confirm the presence and condition of the system.

Why do insurance companies flag knob and tube wiring

Insurance companies often flag knob and tube wiring because of increased fire risk and outdated safety standards. Many insurers require replacement before issuing or renewing coverage.

Can knob and tube wiring handle modern appliances

Knob and tube systems were not built to support today’s high electrical demand from appliances, electronics, and HVAC systems. Overloading circuits can cause overheating and potential failure.

Should knob and tube wiring be replaced or repaired

In most cases, replacement is recommended because repairs do not add grounding or modern safety features. Upgrading improves safety, reliability, and compatibility with today’s electrical needs.

What is knob and tube wiring

Knob and tube wiring is an older electrical system commonly installed in homes built before the 1950s. It uses ceramic knobs and tubes to route wires through walls and ceilings, but it lacks modern grounding and insulation protections.

Is knob and tube wiring dangerous

Knob and tube wiring can pose safety risks because it was not designed for modern electrical loads and lacks grounding. Over time, insulation breakdown and modifications can increase fire hazards.
