I am getting ready to gut my master bath. My house was built in 1972 and has Aluminium wiring. I am wondering if I should rewire that branch with copper while I have everything open. I have done some basic wiring in the past, adding switches and outlets to a branch, but never added a new circuit and run wire. Is this something i can tackle myself? I will be doing all the renovations myself and would prefer not to have to hire someone to do this if I can run it myself.
