Do you have a door that sticks? It won't open or close easily? Want to remove and re-hang it? Repair or replace it? Today, in part I of doors, we'll deal with doors that stick with surefire quick fixes. The problem most likely is just plain old wear and tear, so start by tightening up any loose hinge screws. Do so by hand, rather than with a power drill, so that you don't over-tighten, strip screw holes or chew up the soft screw heads. If one is already stripped, or won't tighten up, try using a longer screw. If that fails, rebuild the screw hole by inserting toothpicks dipped in glue, and driving the original screw in again when it dries. If the door still rubs or sticks, tighten some more with longer screws --.to draw the hinge and jamb in. Extra screws driven through the jamb help, too, on one or both sides. They help open things up. Countersink screw heads, then fill and paint. Tomorrow, in part II, we'll deal with removing and re-hanging. For more tips, visit our Web site at Onthehouse.com.
