FAQs
Why would a Maynardville home need a complete electrical rewire?
Older wiring (aluminum, cloth-covered, or knob-and-tube), frequent breaker trips, flickering lights, or a lack of grounded outlets are common warning signs. A full rewire eliminates fire hazards, brings the system up to current NEC and Union County code, and provides enough capacity for today’s high-demand appliances and electronics.
What steps are involved in your whole-home rewiring process?
1) Initial inspection & load calculation to size the new service. 2) Permit application with the City of Maynardville/Union County. 3) Removal or bypass of existing circuits. 4) Rough-in: running new NM-B or MC cable, installing new breaker panel, bonding & grounding. 5) Mid-project inspection. 6) Trim-out: installing receptacles, switches, and fixtures. 7) Final code inspection and homeowner walk-through to confirm everything works and all drywall repairs are complete.
How long does a typical rewiring project take?
For an average 1,800–2,200 sq ft Maynardville home, expect 5–7 working days for rough-in and 1–2 days for trim-out and inspection. Larger or two-story homes, plaster walls, or custom lighting layouts can add a few extra days. We supply a detailed schedule before work starts.
Will I need to move out or be without power during the rewire?
Most clients stay in the home. We rewire in zones, shutting off only the circuits we’re working on, and set up temporary power for essentials like the refrigerator, HVAC, and Wi-Fi. There is usually a full-day outage when we replace the main service panel, which we schedule in advance.
Do I need permits and inspections for a full rewire?
Yes. Union County and the State of Tennessee require an electrical permit for any whole-home rewire. Our team files all paperwork, coordinates with the local inspector, and ensures the job passes rough-in and final inspections. This protects you, keeps insurance valid, and provides documented proof of compliance.
What does a whole-home rewire cost and what factors affect price?
In Maynardville, most rewires range from $7–$11 per finished square foot. Total cost depends on square footage, number of circuits, panel amperage (100 A vs 200 A), wall accessibility (drywall vs plaster/lathe), smart-home upgrades, and whether service entrance or meter bases need replacing.
