Is knob and tube wiring illegal?

It is not illegal to have, but it cannot be extended under current code, it has no ground, and many insurers will not write or renew a policy on a home that still has active knob and tube.

Do I have to move out during a rewire?

Usually not. We phase the work so the house stays livable, keeping power on to the areas you are using while we rewire the rest.

Will you damage my plaster walls?

Some access is unavoidable, but we fish walls and use existing cavities wherever possible to keep openings small and in low-visibility locations.
