What causes it
Early-1900s homes used ungrounded knob-and-tube wiring, often degraded or unsafely modified over the decades.
What we check
We look for visible knob-and-tube in basements and attics, insulation contact, and amateur splices into modern circuits.
Why it matters
Aged knob-and-tube and insulation contact are fire and insurance issues frequently found in pre-1900 Hastings homes.
