Knob and tube wiring was installed in Detroit residences from the late 1800s through the 1940s. While functional in its era, this ungrounded wiring system cannot support modern electrical loads and often causes insurance companies to deny home coverage.
Consumer Services Electric specializes in the identification, de-energization, and complete modern replacement of knob-and-tube wiring in historic Detroit residences.
Safe, Modern Wiring For Older Detroit Homes
Decommissioning antique porcelain knobs and rubber-sheathed wire with modern grounded circuits.
Knob and tube wiring relies on open-air dissipation to stay cool. Over decades, homeowners and insulation contractors have covered this wiring with fiberglass or blown-in cellulose, creating a fire hazard by trapping heat.
Additionally, knob-and-tube lacks a dedicated grounding conductor, exposing sensitive modern electronics and homeowners to severe shock risks. We trace every run, de-energize the antique system, and pull fresh copper NM-B cabling to all outlets, switches, and fixtures.

- Comprehensive tracing and verification of live knob-and-tube runs
- Removal or safe de-energization of obsolete porcelain tubes and loom
