That will depend on the type of spring in question. Torsion springs tend to be more expensive, but because extension springs always come in pairs, when one is repaired or replaced, the other one will probably also need to be handled similarly. The average cost of spring repair is usually somewhere between a hundred to three hundred dollars including the labor, which depends on the kind of spring (oil tempered, galvanized, etc) and the amount of work involved.
