How the job goes
Comprehensive Assessment
We thoroughly inspect your existing wiring, identifying knob-and-tube, aluminum, or degraded wiring. We assess panel condition, map existing circuits, and evaluate access points through attic, basement, and wall cavities.
Rewire Planning
We design the new circuit layout, plan wire routing to minimize wall damage, and identify where strategic access openings will be needed. You'll know exactly where we need to cut and what the finished result looks like.
Detailed Quote
You receive a comprehensive quote covering the new panel, all wiring, devices, labor, and permits. We itemize the work so you understand exactly what's included. Drywall patching can be included or handled separately.
Permit & Preparation
We pull the electrical permit and prepare the home for rewiring. Furniture is moved or covered in work areas, and we establish our staging area for materials and tools.
New Wiring Installation
Working room by room, we run new copper wiring from the panel location through attic, basement, and wall cavities to every outlet, switch, and fixture location. We use strategic access openings to minimize damage.
Whole-Home Rewiring questions from St. Charles
Do you handle the permit for whole-home rewiring in St. Charles?
Yes. We pull the permit with the office that has jurisdiction at your address, St. Charles County or the City of St. Charles, and schedule the inspection. The permit is included in our quote.
Who is the utility for St. Charles homes?
St. Charles is served by Ameren Missouri or Cuivre River Electric Cooperative, depending on your address. When the work needs the power disconnected or a meter changed, we coordinate it with the utility for you.
Which parts of St. Charles do you serve?
All of St. Charles (63301, 63302, 63303, 63304) and the surrounding area, including St. Peters, Cottleville, Weldon Spring, St. Louis County.
How long does a whole-home rewire take?
Most homes take 3-7 days depending on size, access, and complexity. We work room by room to minimize disruption.
Will you have to cut into my walls?
Some drywall work is usually necessary, but we minimize openings using attics, basements, and strategic access points. We can patch or coordinate with your contractor.
Is knob-and-tube wiring dangerous?
It's not inherently dangerous when intact, but it lacks grounding, can't handle modern loads, is often degraded, and insurance companies frequently require replacement.
What about aluminum wiring?
Aluminum branch wiring from 1965-1973 homes has connection issues. We remediate with a CPSC-recognized method: AlumiConn connectors, COPALUM crimps, or a full copper rewire, with a permit and passed inspection on every job.
