Aluminum branch wiring fails at its connections, not along the wire. Over the decades the metal expands, contracts and loosens under screw terminals. The signs are a warm cover plate, a flickering light or a faint burnt smell at an outlet. In Villanova, we open the boxes, remake each joint with connectors rated for aluminum and replace any scorched device. A full rewire is rare.
The panel is the other 1961 leftover. Federal Pacific and Zinsco breakers can fail to trip, so we replace those panels instead of repairing them. A healthy 100-amp panel might stay, unless you want a Level 2 EV charger or a heat pump. Then 200 amps makes more sense.
Storms matter here too. The remnants of Hurricane Ida cut power and flooded parts of Delaware County in September 2021. A standby generator with an automatic transfer switch keeps a Villanova house running through the next long outage, and as a certified Generac dealer, we size, install and service them.
Our electricians work for Thomas Edison Electric directly, never as subcontractors, and each one leaves from home with a stocked TEE van. The written quote comes first. If we arrive late, the dispatch fee is on us.
