Aluminum wiring question

[Stevenfyeager]

Assuming the customer doesn’t want to spend the money to rewire the house, would you recommend replacing all the devices with AL rated ones or install the copper pigtails?
Thank you.

I would kill the main power and open every device box and tighten the screws.

The improved contact with the now-flattened wire will last another 40 to 50 years.
