We have a 1940 Singer 47 W 70 Darning machine that we use for all of our repairs, Our repairs are all done the old fashion way. The typical repair time is usually 10 days from the time we receive the jeans and the cost ranges from $40-$60 depending on the amount of work needed. Please mail your jeans to the Repair Dept. at the address above. We only repair Jean Shop products, we do not work on other brands.
