Over a period of eight years from 1965, copper branch-circuit wiring was replaced by single-strand aluminum within the electrical systems in many homes - this was due to the rise in price of copper.
Despite being used for nearly a decade, the issues were not realized until later on until it was finally disused as a branch wiring material. When aluminum wiring is properly maintained, it is considered acceptable but it will not last as long as copper due to a few properties of the material itself.
Whenever a home has aluminum fixtures, connections, or switches, their danger increases over time and can create a fire hazard as the wiring overheats from poor connections.
Furthermore, home insurance policies can also be voided by the use of single-strand aluminum wiring which leaves the homeowner unprotected. Before making any drastic changes, it is often recommend talking to insurance agents about the use of aluminum wiring because, if it effects the policy, other solutions may be advisable.

I was contacted by my insurance company that I must replace my existing aluminum wiring within 30 days or my policy will be cancelled. I had my electrical box replaced in 2015. I have 37 outlets and 14 light switches throughout the single-story home. Can you please provide an estimate?
