When you need a rewire

Four reasons Portland homes end up needing a rewire.

The metro's housing stock is older than most. Pre-1940 craftsman bungalows on the east side, mid-century tract homes outer SE and west of 217. Each era has a wiring style that didn't age well.

  • You have knob-and-tube wiring

    Common in pre-1940 Portland craftsman homes. K&T isn't inherently dangerous, but it can't be insulated around, can't be modified safely without re-wiring, and many insurers won't cover homes that still have active K&T circuits.

  • You have aluminum branch wiring

    Common in 1965–1973 builds. Aluminum branch wiring connections loosen over time and become a fire risk at terminations. We replace it or remediate it (CO/ALR devices, AlumiConn connectors) depending on the situation.

  • Outlets are warm or scorched

    A warm outlet means a loose connection generating heat. A scorched outlet means it was on its way to being a fire. Either one needs immediate inspection and re-wiring at that point — usually further than just the visible damage.

  • Renovation, addition, or ADU

    Full or partial rewires often come up during a kitchen remodel, basement finish, attic conversion, or ADU build. Easier to do during the open-walls phase than after the drywall goes up.

Smell something burning, see scorched outlets, or notice repeatedly tripping breakers? Shut the affected circuits off at the panel and call us. Old wiring failures can cascade into fires fast.

How it works

Our rewiring process — four steps from assessment to inspector sign-off.

  1. 01

    In-home assessment

    We walk every accessible junction, identify what's K&T versus modern Romex, check terminations at the panel, and write you a real scope — not a one-line estimate.

  2. 02

    Scope + permit

    Full rewire, partial rewire, or selective remediation. Permits pulled with the AHJ (BDS, Multnomah, Clackamas, Washington). We tell you up front what walls have to come open and what stays.

  3. 03

    Pull, terminate, label

    New runs pulled cleanly. Boxes leveled and flush. Every circuit labeled in the panel and at the device. Drywall cuts kept as tight as the work allows.

  4. 04

    Inspection + drywall plan

    City or county inspector signs off the rough-in (if walls are open) or the finished work. You get the paperwork. We coordinate the drywall repair plan if it isn't part of a larger remodel.

Old Portland homes, modern code

We've been in enough pre-1940 attics to know what we're looking at.

Inner SE craftsman attics, SW Hills basement junction boxes, outer SE post-war slabs — every Portland-metro housing era has its own wiring quirks. We don't bid blind, and we don't leave the house in worse shape than we found it. Drywall cuts stay tight; circuits get labeled; the panel finally makes sense to read.

  • Knob-and-tube remediation and full replacement
  • Aluminum branch wiring remediation (CO/ALR, AlumiConn)
  • Partial rewires during kitchen or basement remodels
  • Insurance documentation on completed work

Wiring & rewiring questions, answered.

  • Full rewires on pre-1940 Portland homes typically run $15,000–$35,000 depending on square footage, accessibility, and how much knob-and-tube is still active. Partial rewires (kitchen, basement, single floor) are smaller projects — typically $3,500–$12,000. We quote flat-rate after the in-home assessment.
