However, some homes still have it, or may have a knob and tube wiring system that was incorrectly modified or rigged to work with a modern electrical system. Knob and tube wiring may contain asbestos insulation, but the only way to know is to have the material professionally tested.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Regulations require certified professionals for removals and disposal in compliance with local and federal guidelines, ensuring safety and legality.
