Does Your O'Fallon Home Need Rewiring?

Much of O'Fallon was built during St. Charles County's rapid growth from 1990 to 2015. As one of Missouri's fastest-growing cities, O'Fallon has a high concentration of newer homes with growing electrical loads from EVs and home additions. Key signs your O'Fallon home may need rewiring include: two-prong ungrounded outlets throughout, aluminum branch wiring, knob-and-tube wiring, frequent breaker trips, burning smells, or a home that hasn't been rewired in 40+ years.

Aluminum Wiring Remediation in O'Fallon

Homes built in O'Fallon between 1965 and 1982 may have aluminum branch wiring, which is a fire hazard at outlet and switch connections. The safest long-term fix is rewiring with copper. A shorter-term option is COPALUM crimping at all termination points — we do both and will recommend the right approach for your home.

Knob-and-Tube Wiring Replacement in O'Fallon

Knob-and-tube wiring — found in many older O'Fallon homes — lacks a ground wire, is incompatible with modern insulation, and is rejected by most insurance companies. We replace it completely with modern grounded copper wiring, to code, with all required St. Charles County permits.
