Knob and Tube Wiring in Illinois Homes: Risks, Insurance and Replacement

Still have knob and tube or aluminum wiring? Learn the fire and insurance risks, how whole house rewiring works in Illinois, and what to expect on cost and timeline.

By the LED Electric team ยท Updated 2026-11-08

How to recognize it

Ceramic knobs and tubes in the basement or attic, two-prong outlets throughout, and cloth-covered wires are tell-tale signs.

Why insurers care

Knob and tube has no ground, degrades with heat, and is often buried under insulation โ€“ a fire risk. Many carriers decline or surcharge policies.

Aluminum wiring (1965โ€“1973)

Aluminum branch wiring expands and loosens at connections. It can be remediated with approved connectors or fully replaced.

What rewiring involves

We fish new grounded cable through walls, add AFCI/GFCI protection, and patch minimal openings. Most homes stay occupied during the work. Read more on whole house rewiring.
