Cost Factors for Home Rewiring Projects in Prineville Oregon

Rewiring a typical Prineville home costs somewhere between $3,500 and $12,000+, with most single-story homes in the 1,200–1,800 sq ft range landing around $6,000–$9,500 for a full rewire. The wide spread exists because the biggest cost drivers aren't the wire itself — it's access, wall type, and how much of the old system has to come out before new wiring goes in. On a place with a crawlspace and open attic, our crew moves fast. On a slab home with plaster walls near Downtown, the same job can take twice as long.

Home Age and Construction Type Drive the Bulk of the Cost

Crook County has a real mix of housing stock — older homes near Downtown Prineville with original knob-and-tube or cloth-insulated wiring from decades past, and newer builds out toward the edges of town with modern Romex already in place. The older the home, the more likely we're dealing with undersized circuits, no ground wire, and outdated panels that can't be reused. That means a rewire often turns into a combined project with an electrical panel upgrade, since running new 12-2 and 14-2 wire into a 60-amp or 100-amp panel that's already maxed out doesn't solve the underlying problem. Plaster-and-lath walls, common in older Prineville homes, also add labor because we have to cut and patch access points instead of just fishing wire through open stud bays like we can in newer drywall construction.

Square Footage and Layout Complexity

Cost scales with square footage, but not in a straight line. A single-story ranch with a simple rectangular footprint is the cheapest to rewire per square foot because access is easy and runs are short. Multi-story homes, additions built at different times, or homes with finished basements cost more because we're often fishing wire through finished ceilings and walls with no easy attic or crawlspace path. Expect these rough ranges based on layout:

• Single-story, open attic/crawlspace access: $3.50–$6/sq ft

• Multi-story or finished basement: $6–$9/sq ft

• Additions with mismatched framing or plaster: $8–$12/sq ft

Homes on the outskirts toward Powell Butte or Terrebonne often have detached shops or barns that get bundled into the same rewire quote, which changes the per-project total even though the per-square-foot rate stays similar.

Panel Capacity and Circuit Count

A rewire isn't just about swapping wire — it's about whether the panel can support the number of circuits a modern home actually needs. Older Prineville homes often have a single 100-amp panel feeding a kitchen, laundry, and whole house on far fewer circuits than current code would call for. If your panel is already full or corroded, budget for a panel upgrade alongside the rewire — trying to save money by skipping it usually just means a callback in a year or two when breakers start tripping under load. We also check every outlet and switch box during a rewire, and it's common to find deteriorated devices that need replacing anyway; see our outlet and switch repair work for what that typically involves.
