One area of significant concern with older home inspection is the wiring. During the period between 1930 and 1950, when household demands for electricity were much lower, most home wiring included a type of wiring called knob and tube. Today’s homes use much more current to run all of the newer appliances families require to live a comfortable lifestyle. In older homes with this type of wiring fires are much more of a risk.
A simple trip to the basement of your house can reveal if you have this type of current system. If you see white knobs attached to the joists with wires running through them, chances are this is knob and tube wiring. The knobs acted as insulators from objects while the ceramic tubing provided the support for wires as they travel through floor joists.
Older home inspection today requires catching this type of wiring system with recommendations of complete replacement in order to avoid costly or life threatening fires. This includes replacement of not only the fuses but the wires as well. Simply put, If you upgrade the panel, then replace the wiring as well.
An important side note is that a lot of insurance companies will not write or renew policies where there is existing knob and tube wiring. Nothing can be more frustrating than finding out your proud real estate purchase will not be covered prior to closing.
Rather than hoping your house passes inspection, make sure your professional older home inspection includes the wiring system and recommendations for replacement before it causes undue headache.
