Electrical Wiring Repair in Portland, OR & the Metro Area

Chewed cable, burnt splices, open junctions, a previous owner's handiwork — the damaged section repaired, not the whole house, across Portland, Clackamas, Troutdale, and surrounding communities.

Electrical wiring repair is for damage on part of a circuit that you can see, or that has already been found: cable chewed by mice in an attic or crawlspace, a splice overheated until its insulation turned brittle, wires a previous owner taped together in a joist bay, a cable a drywall screw went through during a remodel. The rest of the house may be fine; the job is the damaged length.

We switch off the circuit, follow it from the panel, and find every damaged spot, not just the first. Damaged runs are replaced box to box with new cable. Any splice goes in a covered junction box that stays reachable, never buried in a wall — open splices from earlier amateur work included. Where a cable was cut behind a finished wall, we open the wall at the damage, not across the room, then test the circuit under load.

Wondering whether a previous owner's wiring was ever permitted? Look the address up on PortlandMaps: the permit history lists electrical permits back for decades. A finished basement, an attic bedroom or an added bathroom with no electrical permit on record is where we start looking for taped splices and cable run without protection.

Rats and mice are the most common reason we replace a short length of cable in Portland. Roof rats travel along attic framing and Norway rats live in crawlspaces, and both chew insulation off live wire. Multnomah County Vector Control answers rat questions and can advise on sealing entry points. Seal the house first, or the new cable is chewed next.
