GE clothes washer belt change price

Whatever service rates are for the area. Here they're about $45-50/hr. I'd expect metro areas to perhaps be at least 50% higher.

Are you asking "how much labor to charge"? Or what to charge him for the belt.

If the landlord owns it, you're doing it for the landlord and it would be appropriate to expect a reasonable labor. It's $75 per hour here with a typical one-hour minimum. But you don't have a typical service company's overhead -- taxes, Soc. Sec., sick leave, vacations, insurance, etc., etc. $40 bucks would be more than fair barring any complications.

If your friend owns it, and he/she's a close friend, I'd have to ask why you charge anything other than the part cost? It's not that difficult a repair job anyway.

Just curious as heck : )

If it's for a friend, I'd have him buy the part and wouldn't charge him for my time. If you're going to take his money you have to be ready to do a professional job, including being willing to guarantee your work and make return visits if something goes wrong -- for example, if the belt broke because of some other problem you hadn't spotted, etc.
