A drive belt runs $6 to $14 in parts and about twenty minutes on the bench. A motor brush set is $10 to $20. A tension assembly rebuild on a sewing machine runs $35 to $60 depending on how far it has to come apart. We quote the part and the labor as two numbers, not one, so you know which one you are paying for.
Cheap parts break the same way every time, which is why we can quote most jobs before we even open the housing. What we cannot quote sight unseen is a motor that has been run dry or a gear that has stripped - those get an in-person look before any number goes out.
If a repair would cost more than a comparable new machine, we say so before you pay a diagnostic fee, not after.
