Whole-House Rewiring in St. Louis

Whole-House Rewiring Services

St. Louis has some of the oldest housing stock in the Midwest, and thousands of homes across the metro still have wiring that's decades — or even a century — past its intended lifespan. Knob-and-tube wiring from the early 1900s, aluminum wiring from the 1960s-70s, and early Romex from the 1940s-50s all present safety risks that grow worse with age. We specialize in rewiring older St. Louis homes safely and efficiently.

Aluminum Wiring Remediation

Tens of thousands of St. Louis homes — particularly in Florissant, Hazelwood, Ferguson, Ballwin, and other areas that saw heavy development in the 1960s and early 70s — were wired with aluminum. The wiring itself isn't the problem; it's the connections. Where aluminum meets copper at outlets, switches, and the panel, the metals expand at different rates with heat cycles. Over time, connections loosen, oxidize, and can arc — starting fires inside your walls.

We install purple COPALUM crimp connectors or AlumiConn lugs at every connection point in your home. This is a proven, code-compliant fix that eliminates the hazard without the cost and disruption of pulling every wire in your house. For homes with extensive aluminum wiring damage or where a full rewire makes more economic sense, we do that too.

Knob-and-Tube Wiring Replacement

Knob-and-tube wiring is found throughout South City, Tower Grove, Kirkwood, Webster Groves, and other neighborhoods with pre-1950 housing. This wiring runs through ceramic knobs and tubes in your walls and attic. The insulation deteriorates over decades, and the system was never designed for grounded circuits or modern electrical loads. Many insurance companies won't cover homes with active knob-and-tube, and it's a red flag in any home inspection.

We carefully remove old knob-and-tube wiring and replace it with modern NM-B (Romex) cable, adding proper grounding throughout. We work through plaster walls and around original woodwork with care, minimizing patching and disruption.

When Does a Home Need Full Rewiring?

• Knob-and-tube or cloth-insulated wiring anywhere in the home
• Aluminum wiring with evidence of overheating at connections
• Insurance company requiring wiring upgrades for coverage
• Home inspector flagging wiring during a sale
• Frequent tripping, flickering, or burning smells with no panel issue
• Planning a major renovation where walls will be opened anyway
• Two-prong outlets throughout with no ground wire available

Our Rewiring Process

We start with a thorough assessment of your home's existing wiring. We map every circuit, identify all problem areas, and provide a detailed estimate. During the rewire, we work room by room to minimize disruption — you don't need to move out. We install new wiring, grounded outlets, proper junction boxes, and connect everything to a new or upgraded panel. All work is permitted and inspected.
