My insurance company says I have to remove all knob-and-tube. Do I?

Maybe. Some carriers require full removal; others accept abandonment in place if it's no longer energized. We document what's live, what's dead, and what's been replaced — and write the letter your underwriter actually wants.

Knob-&-Tube

Historic Remediation

Knob-and-tube, cloth wire, two-prong. Sorted, safely.

Frederick has a lot of houses older than the National Electric Code. We open walls only where we need to, abandon legacy circuits cleanly, and rewire one room at a time so you're not living in a job site for six weeks.

What that looks like on a real job.

Knob-and-tube, cloth-jacketed, & aluminum wiring assessment
Phased rewires (one floor or one room at a time)
GFCI / AFCI retrofit on legacy circuits where rewiring isn't feasible
Sensitive work in plaster-and-lath, brick, & post-and-beam
Insurance-letter documentation when underwriters ask for it
