Aluminium wiring is very common in homes built in the 1960's- 1980's.  At the time, it was considered to be efficient, durable, and cheap, making it ideal for wiring homes. As time passed, however, problems with the installation of the wire arose, posing serious risks to homeowners. These risks include deterioration of wires, arcing, overheating, as well as expansion and contraction of the wiring. Aluminum wire is no longer permitted in homes because of its hazardous characteristics. An aluminum electrical system is assumed to have a life of 25 - 30 years. At this age problems are very likely to occur. Please call McNatt Electric for any electrical repairs you may need.
