Whole-Home Rewiring in Twin Falls, ID
Plenty of homes across Twin Falls and the Magic Valley are running on wiring installed before modern electrical demand existed — back when a house had a handful of circuits and the biggest load was a refrigerator. Today’s homes run central air, electric dryers, home offices, EV chargers, and dozens of always-on devices, all through wires that were never designed for it. A whole-home rewire replaces that aging, undersized, or unsafe wiring with a modern system built for how you actually live.
Twin Falls Electrician performs complete and partial home rewiring for houses across Twin Falls, Kimberly, Jerome, Buhl, Filer, and the surrounding Magic Valley. Every rewire starts with a thorough assessment and an exact, upfront price. Call (208) 423-0044 for a free on-site evaluation.
Signs Your Home Needs Rewiring
Most homeowners don’t think about their wiring until something goes wrong — but the warning signs are usually there first. Call us for an assessment if you notice any of these:
- Aluminum branch wiring: Common in homes built between the mid-1960s and mid-1970s, aluminum wiring expands and contracts at connections, which loosens terminations over time and creates overheating and fire risk at outlets and switches.
- Knob-and-tube wiring: Found in the area’s oldest farmhouses and early-1900s homes. It has no ground wire, the insulation is decades past its lifespan, and it’s often been buried under attic insulation — a combination insurers hate.
- Cloth-insulated or brittle wiring: If the insulation crumbles when touched, the wire is done. This is common in mid-century homes across the valley.
- Frequent breaker trips or blowing fuses: A circuit that trips regularly is telling you it’s overloaded — and if the panel is old, the breaker itself may not be protecting you properly.
- Burning smells, scorch marks, or warm outlets: These are urgent. Cut power to the affected circuit and call us — this is emergency territory.
- Two-prong outlets throughout the house: No ground means no safe path for fault current, and it means your wiring predates modern safety standards by decades.
- Flickering or dimming lights: Occasional dimming when a big appliance kicks on can be normal; frequent or worsening flickering points to loose connections or undersized wiring.
Our Whole-Home Rewiring Process
A rewire is a bigger project than most electrical work, so we run it like one — planned, phased, and communicated clearly from day one:
1. Assessment and plan. We inspect your panel, attic, crawlspace, and a sample of outlets and fixtures to map what’s there. Then we design the new system: circuit layout, outlet and switch locations, dedicated appliance circuits, and any upgrades you want folded in (recessed lighting, USB outlets, smart switches).
2. Permits. We pull the required electrical permits with the local authority having jurisdiction and schedule inspections at the rough-in and final stages.
3. Phased room-by-room work. We rewire in sections so you’re never without power to the whole house longer than necessary. Old wiring comes out, new cable goes in — fished through walls and ceilings wherever possible to minimize drywall damage.
4. Panel and devices. The new wiring terminates in your panel — upgraded first if needed (see below) — and we install new receptacles, switches, and cover plates throughout.
5. Inspection and testing. After the final electrical inspection passes, we test every circuit, outlet, and GFCI/AFCI device, then walk the whole house with you.
Rewiring and Panel Upgrades Go Together
It rarely makes sense to run brand-new wiring into a 60-amp fuse box. Most rewires pair naturally with a panel upgrade to 200 amps, giving the new wiring a modern, code-compliant home with room for today’s loads and tomorrow’s additions — EV chargers, hot tubs, workshops. We evaluate your panel during the assessment and quote the rewire and panel as one coordinated project, which costs less than doing them separately.
What Affects the Cost of a Rewire
Every house is different, which is why we price rewires on-site rather than over the phone. The main cost drivers:
- Home size and layout: More square footage and more rooms mean more circuits, more devices, and more labor.
- Accessibility: An open attic and accessible crawlspace make fishing wire straightforward; finished basements, flat roofs, and plaster walls add labor.
- Panel condition: If the panel needs replacement or a service upgrade, that’s part of the project scope.
- Wall and ceiling finishes: Drywall patches are quick; plaster and textured finishes take more restoration.
- Add-ons: Many homeowners use a rewire to add recessed lighting, extra outlets, dedicated home-office circuits, or hardwired smoke and CO detectors — smart to do while the walls are open.
You’ll get an exact written price before we start, and it won’t change unless the scope changes at your request.
Rewiring Older Magic Valley Homes
We rewire a lot of farmhouses and mid-century homes across Twin Falls County, Jerome County, and Gooding County — houses built when 60-amp service and a fuse box were standard issue. The pattern is familiar: an original panel that’s been “upgraded” with bigger fuses than the wiring can handle, splices buried in walls without junction boxes, and decades of DIY additions layered on top. Our residential electricians have seen it all, and we bring these homes up to current code without gutting them — fishing new wire through existing walls and ceilings keeps the disruption (and the drywall repair) to a minimum.
If you’re not sure whether your home needs a full rewire or targeted repairs, start with electrical troubleshooting or a safety inspection. Sometimes the right answer is a panel upgrade and a few new dedicated circuits — we’ll tell you honestly which one your house needs.
Frequently Asked Questions
How long does a whole-home rewire take?
Most single-family homes take several days to two weeks depending on size, accessibility, and scope. We give you a firm schedule with the quote and phase the work so you keep power to the parts of the house we’re not actively working on.
Do I have to move out during a rewire?
Usually not. We work room by room and restore power to finished sections each day. You’ll have some disruption — furniture moved, attic access open — but most families stay in the home throughout.
Will you have to cut holes in my walls?
Some, yes — but far fewer than you’d expect. We fish most new wiring through attics, crawlspaces, and existing wall cavities. Openings are kept small, and we patch drywall as part of the job.
Does a rewire include a new electrical panel?
It should, if your panel is undersized or outdated — and most panels in rewire-age homes are. We assess the panel during the estimate and include the panel upgrade in the project when it’s needed.
Can you add outlets, lighting, or circuits during the rewire?
That’s the best time to do it. While walls are open, adding recessed lights, extra outlets, USB receptacles, or dedicated circuits costs far less than doing it as a separate project later.
