You have to charge something for your time. If it was a quick fix I would say don't charge, but they should be charged for a bathroom remodel. My DH is a mechanic and everyone wants him to fix their car for free. If he is going to spend the weekend fixing your car he needs to be paid for his time.

I used to be the family tech support and computer fixer, and I freaking hated it. There were times when a family member would drop of their virus ridden machines or crashed hard drives and ask me to either restore them or save their pictures, I literally spent hours and hours sometimes (unpaid). Now I just tell them that computers have become too complex and I haven't kept up with it, so I don't have to do it anymore. 4951
