Scorched wiring in the garage needs an electrician's eyes before you close
What we found
Visible scorching — dark discoloration on the outer jacket — was observed on a Romex cable (a common type of plastic-jacketed household wiring) in the garage, behind the laundry equipment. The discoloration was more pronounced at the staple points where metal fasteners hold the cable against the wood framing.
Why it happens here
Romex cable carries electrical current between your panel and the devices on that circuit. The staples are there to keep the cable tidy and protected against physical damage. When resistance — the friction that electrical current experiences moving through a conductor — increases at any point along a wire, heat concentrates there. The staple locations are the spots where the discoloration is most visible, which is where the heat appears to have been greatest.
What it means for you
Scorching on a conductor is a sign that heat has been present at or inside that cable. Electrical arcing — a discharge of current through the air — and fire are recognized risks associated with overheated wiring, and a licensed electrician needs to determine how far the condition extends and what the right fix is.
What to do
Have a qualified, licensed electrician evaluate this wiring before your inspection contingency expires. They can assess the full extent of the condition and advise on the appropriate corrective work.
How common is this
Inspectors routinely examine visible wiring for signs of heat damage and report what they find. When scorching is present, an electrician's evaluation is a standard next step.
An electrician's assessment before closing gives you a clear picture of the scope and your options.
