A 1920s Pasadena home-purchase inspection uncovered active knob-and-tube wiring blocking the buyer’s insurance approval. Our electrician traced the K&T runs, fished modern Romex to the original device boxes without cutting into the plaster, and installed grounded, AFCI/GFCI-protected receptacles. The home passed insurance re-inspection. This is the kind of job we handle regularly in Pasadena’s historic neighborhoods.

Insurance Requirements for Older Homes
Many insurance carriers require knob-and-tube wiring to be replaced, or won’t write a new policy until it is. We provide a detailed C-10 safety audit, megohm insulation resistance testing, active K&T removal, and an official completion certificate your insurance broker can use directly.
Our Replacement Process
We inspect and trace the existing K&T runs throughout the home, fish modern, grounded wiring to the original device boxes without cutting into plaster wherever possible, install AFCI/GFCI-protected receptacles and confirm everything passes inspection, and provide a completion certificate for your insurance broker.
