Sounds like you need to drop the fender down closer to the tire. If there is room to drop it down you can buy either a straight or an angle bracket at your local hardware store and either extend or replace the current bracket. It depends on how the current bracket is attached to your fender.
I have also used nylon wire-ties to attach fenders on some bikes where the standard mounting methods won't work.
