FAQs
Why would I need a whole-home rewire instead of partial repairs?
Homes in Harriman built before the 1980s often contain dated aluminum or knob-and-tube wiring that can overheat, trip breakers, or fail modern electrical code. A complete rewire replaces every branch circuit, receptacle, switch, and lighting run with modern copper conductors, grounded outlets, and AFCI/GFCI protection, eliminating hidden fire hazards and giving you the capacity to power today’s high-demand appliances and electronics safely.
How long does a typical whole-house rewire in Harriman take?
An average 1,500–2,000 sq ft residence usually takes 5–10 working days, depending on the home’s age, wall construction, and how much finished surface restoration is required. Larger or historic homes with plaster walls can take two to three weeks. We provide a detailed day-by-day schedule before work begins so you know exactly what to expect.
Do I have to move out while my house is being rewired?
Most clients stay in their homes. We rewire one zone at a time, maintaining temporary power to essential circuits such as the refrigerator and HVAC. However, there will be daily shutdowns of specific areas, and some dust and noise. If you work from home, have small children, or cannot tolerate daily disruptions, arranging temporary accommodations may be more comfortable.
What is the cost range for a whole-home rewire in Harriman?
Costs vary with square footage, number of circuits, accessibility, and service-panel upgrades. In Harriman, a full rewire generally ranges from $7 to $11 per square foot. A 1,800 sq ft home might run $13,000–$20,000, while larger or custom projects can exceed $25,000. After a free on-site assessment, we provide a fixed-price proposal that includes labor, materials, permits, drywall repair, and final inspection fees—no surprises.
What permits and inspections are required, and who handles them?
Roane County and the City of Harriman require an electrical permit for any whole-home rewire. Rough-in and final inspections by a certified electrical inspector are mandatory before walls can be closed and the utility can reconnect full service. Our licensed master electricians obtain all permits, coordinate the inspections, and supply you with the approved inspection reports for your records and homeowners-insurance documentation.
Can you add service-panel upgrades, EV chargers, or smart-home wiring during the rewire?
Yes. A whole-home rewire is the ideal time to future-proof your electrical system. We can upgrade your main service to 200 amps or higher, install sub-panels, run dedicated circuits for electric vehicle chargers, hot tubs, or workshop equipment, and pre-wire for Ethernet, security cameras, and whole-house audio. Bundling these upgrades with the rewire saves labor costs and avoids opening the walls a second time.
