Is it hard to sell a house with aluminum wiring?

Selling a house with aluminum wiring is harder than selling one with copper, but thousands of them sell every year. The wiring itself is legal. The friction comes from insurers and inspectors.

Many insurance companies surcharge or decline homes with 1960s and 70s branch-circuit aluminum, and buyers hear that during escrow. Home inspectors flag it by default.

Two fixes carry most of the weight. AlumiConn or COPALUM pigtail repairs at every device satisfy most insurers for far less than a rewire. A letter from a licensed electrician documenting the remediation calms buyers down.

Whether it is worth buying or keeping such a house usually comes down to that repair math, not the metal.

Sizing the copper replacements starts with the copper to aluminum wire conversion calculator, which shows the equivalent gauge for every circuit.
