For your PROTECTION, get an INSPECTION! 🕵️♂️
Sometimes the biggest electrical hazards are hiding in the attic!
During this inspection, we discovered energized knob-and-tube wiring, identified using a non-contact voltage tester.
Knob-and-tube wiring was commonly installed in homes from the 1880s through the 1940s and was largely phased out in new residential construction by the 1950s.
While this wiring method was acceptable during its time, aging insulation, improper modifications, and the absence of equipment grounding can present serious electrical safety concerns.
What makes this discovery particularly concerning is the presence of attic insulation and combustible materials near the wiring. Active knob-and-tube wiring should not be covered with thermal insulation, as it can interfere with heat dissipation and increase the risk of overheating and fire.
We recommend evaluation by a licensed electrician to determine the condition of the wiring and appropriate corrective measures.
Just because the lights still work doesn't mean the electrical system is safe!
