Do they repair sewing machines? And how much do they charge?

There's a sewing machine shop on Charleston between Arville and Valley View. They've been in that location since I was little, and I'm 51 now. Im almost positive they can help you. Good luck

Yes they have a repair person in store the cost varies depending on the model and what's wrong

I don't think so. You should look for a sewing and vac. shop. The usually repair. Cost varies
