Cloth-Covered and Ungrounded Wiring
- What it looks like
- Wires wrapped in fabric instead of plastic, often seen in the attic or basement. Very old knob and tube wiring runs on white ceramic posts.
- Why it matters
- The cloth and rubber dry out and crack with age. Most of this wiring has no ground wire, which is what protects you from shocks.
- What we do
- We check its condition and replace the worst runs first, or rewire the house in stages.
