Fish-cabled K&T replacement that preserves plaster and period detail — a Westside Victorian specialty.
A knob-and-tube rewire replaces the live knob-and-tube circuits in your house with new grounded wiring, fished through the walls you already have rather than opened out of them. The plaster, the crown, the picture rail, and the cased openings stay where they are.
Knob-and-tube is the wiring method used in American houses from roughly the 1880s into the 1940s. Two separate conductors — one hot, one neutral — run through open air, held on ceramic knobs along the framing and passed through ceramic tubes where they cross a joist or a stud. No sheathing. No equipment ground. The insulation is rubber or cloth, and after a century it is brittle where it has not already gone. It was careful work for its era. What it never anticipated was blown-in attic insulation packed around runs that were designed to shed heat into open air, decades of renovation splices made by whoever was handy, and a household that runs a microwave, a hair dryer, and a space heater at once.
Most of these houses are not entirely knob-and-tube. Decades of partial upgrades leave a mix, so the first real job is telling live knob-and-tube from abandoned knob-and-tube, and both from the cloth-insulated cable somebody ran alongside them in the 1950s. The live runs are what we replace. Genuinely dead historical runs can stay where they are — pulling them out of a finished plaster wall does damage for no gain — and we write down what stayed, what came out, and why. That record is the thing an underwriter or a buyer's inspector asks for later, and it is worth more than a verbal assurance that the house has been done.
Fish-cabled means the new wire travels through cavities that already exist: down stud bays from the attic, up from the crawlspace, often along the same paths the original installers used. Access holes happen only where framing blocks a run. In a Victorian that matters more than it does in a tract house, because lath and plaster does not patch the way drywall does, and the period detail that makes the house worth keeping is exactly what a gut-and-rock approach destroys. We keep the access holes minimal, document every one, and hand the patch list to your plaster or finish contractor. Wall repair itself is not our scope, and we say that before you sign anything. When it is done, every circuit has an equipment ground, so three-prong outlets are legitimate instead of an adapter over a two-prong hole. GFCI and AFCI protection goes in where current California code calls for it, and hardwired smoke and carbon-monoxide detectors go in per code. The panel stays a separate question — houses of this vintage often still have a fuse panel or a small service, and if yours does, that is its own project on its own line. Rewiring an occupied, finished, plaster-walled house is a different craft from wiring a job site, and it is the craft this company is built around.
A tech walks the attic, basement, and crawlspace, identifies which knob-and-tube is still live, checks the panel and service, and writes up what is actually in the house. Many of these homes carry three wiring generations. Written report and a real quote, no obligation.
We map circuits to rooms and set the order of work so you keep power and a usable kitchen throughout. The permit goes in with the County for unincorporated addresses, or with the city in Santa Cruz, Capitola, Scotts Valley, or Watsonville.
New cable goes in through existing cavities and live knob-and-tube comes out of service as each area finishes. Access holes only where framing blocks a run, each one photographed. Progress inspections at the milestones the building department requires.
Final sign-off, every circuit labeled at the panel, the smoke and carbon monoxide detector network verified, the patch list handed to your finish contractor, and the documentation package delivered — permit number, inspection sign-off, and the written record of what was replaced and what was left.
Rewires are the most house-specific work we do, and a Victorian is the most house-specific version of that. The quote is real only after a tech has been in the attic and under the floor, seen the framing and the access, and worked out how much of the knob-and-tube is actually still live. Quotes are free and phased so the numbers stay legible — the rewire and any panel work always appear as separate lines. The factors below are what genuinely move the number.
“Sunrise Electrical rewired our house, replacing the old knob-and-tube wiring with seamless, safe, and up-to-code wiring at a very reasonable price. They were incredibly efficient, worked cleanly, and addressed all our questions and concerns with care. We can't recommend them highly enough!”

We'd rather you get the right outcome than the Sunrise outcome. Some of this points away from us on purpose.
Look for a CSLB-licensed C-10 contractor and verify at cslb.ca.gov. Ask specifically for references from occupied pre-1950 rewires, and ask how they plan to get new cable through the walls. You want to hear about fishing paths, where access holes would land, and who handles the patch list — that is the difference between a rewire your plaster survives and one it does not. The work should always include a permit and a building-department inspection.
