It was perfectly legal and compliant with the standards of the time. The catch: aluminum doesn&#8217;t age like copper. Over time, its connections can become a real hazard \u2014 and insurers know it. At <strong>Groupe Quenneville<\/strong>, we see this situation almost every week. Here&#8217;s the straight talk \u2014 no scaremongering, but nothing hidden.<\/p><\/div><\/section>\n<section class=\"section band\"><div class=\"wrap\"><div class=\"narrow center\"><span class=\"kicker\" style=\"color:var(--heat)\">The danger, explained<\/span><h2 style=\"margin:16px 0 18px;\">The problem isn&#8217;t the wire.<br>It&#8217;s its connections.<\/h2><p class=\"lead\" style=\"margin-bottom:8px;\">At connection points \u2014 outlets, switches, panel \u2014 three phenomena add up and create invisible hot spots.<\/p><\/div>\n<figure><img decoding=\"async\" src=\"https:\/\/groupequenneville.com\/wp-content\/uploads\/2026\/07\/illus-aluminium-mecanisme.png\" alt=\"The three phenomena behind aluminum wiring danger: expansion, oxidation and hot spot\"><figcaption>Groupe Quenneville illustration \u2014 how an aluminum connection fails.<\/figcaption><\/figure>\n<div class=\"narrow\"><p>The aluminum wire itself isn&#8217;t the culprit: it&#8217;s the <strong>junction<\/strong> that&#8217;s the problem. A connection loosened by expansion, then insulated by oxidation, develops electrical resistance. This resistance generates heat exactly where you can&#8217;t see it \u2014 behind a wall plate, in a junction box, at the panel.
