Knob and Tube Wiring Replacement FAQs – Alamo

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.

Are your electricians in Alamo local?

Yes. Our technicians are dispatched locally in and around Alamo, so you get faster service from electricians who know the area.
