Knob and Tube Wiring Replacement FAQs – Millbrae

Is knob and tube illegal?

Existing wiring is allowed in many areas, but it cannot be extended and insurers often refuse to cover it.

Can I insulate over it?

No. Covering knob and tube with insulation is a fire hazard and a code violation.

How do you minimize wall damage?

We fish new cable through existing paths and make small, patchable openings.

How quickly can an electrician get to my home in Millbrae?

Same-day service is available for most calls in Millbrae, and emergency dispatch typically arrives within 60 to 90 minutes.
