01. The "Creep" Effect
SUBJECT: ALUMINUM WIRING (1965-1973)
Copper shortages in the Vietnam era forced builders to use single-strand aluminum. The physics are fatal: Aluminum expands and contracts 30% more than copper.
Over time, this movement loosens the connection screws. This gap creates a high-resistance arc (mini-lightning) that reaches 5,000°F. It is not a matter of if it will fail, but when.
THE FIX: We use the AlumiConn / COPALUM method to permanently bond copper "pigtails" to the ends, stopping the expansion cycle without tearing down walls.
02. The Insulation Decay
SUBJECT: CLOTH / KNOB & TUBE (Pre-1960)
Before plastic (PVC), wires were wrapped in rubberized cloth. After 70 years in a hot attic, that cloth becomes brittle.
Simple vibrations—like walking on the floor above or a door slamming—can cause the insulation to flake off completely, leaving bare live wires exposed against dry wooden studs. This is an immediate fire hazard that insurance companies will often refuse to cover.
03. The Missing Pathway
SUBJECT: UNGROUNDED OUTLETS
If you have 2-prong outlets, your home lacks a "Grounding Conductor."
Without a ground, a power surge has nowhere to go but into your sensitive electronics—or through your body if you touch a metal appliance. Surge protectors are functionally useless on ungrounded circuits.
