Service Overview
What's included
Knob-and-tube wiring was the standard in homes built before 1940. While functional when installed, this open-air wiring system is now considered a serious fire hazard. Insulation added over the wires causes overheating, and the lack of ground wire creates shock risks. Many insurance companies now refuse to insure homes with active knob-and-tube wiring, or charge significantly higher premiums. Banks may also decline mortgages for homes with this outdated system. Our knob-and-tube replacement service removes all active K&T wiring and replaces it with modern, grounded Romex. We carefully trace each circuit, ensuring no live K&T remains hidden in walls or attics. The result is a safe, insurable, and code-compliant electrical system.

Knob-and-Tube Replacement FAQ
Common questions about knob-and-tube wiring replacement in St. Louis.
Is knob-and-tube wiring dangerous?+
Yes. While K&T was safe when installed, modern usage patterns and added insulation create fire hazards. The wires were designed to dissipate heat in open air—covering them with insulation causes overheating.
Will my insurance drop me if I have K&T?+
Many insurers won't write policies for homes with active K&T, or charge 20-30% higher premiums. Some require K&T removal within 30-60 days of policy inception.
Can I just remove the K&T myself?+
No. K&T removal requires a licensed electrician and permit. The work must be inspected to verify all active K&T has been removed and proper connections made.
Do you remove the old knobs and tubes?+
We remove all accessible K&T components. Some may remain in inaccessible wall cavities, but all circuits will be de-energized and cut at both ends.
