over the summer... i paid a certified electrician to pig tail all of my aluminum wiring outlets into copper... then, i had him replace my breaker box which is known to cause fires aka federal pacific electric... cost: 3k... after seeing him do it... and he even taught me how to do it thereafter he charged me but... it didn't seem too hard... btw, does anyone need a un-certified diy electrician...? i could potentially give you a new breaker box and pigtail aluminum wires into copper... but if your house should go up in flames... i ain't responsible... cost: will work for beer... lol!
