How do I stop my door from sticking in the winter?
Open and close the door over the sandpaper several times to remove material from the door’s bottom edge. Try lubricant. Determine where the door is sticking and lubricate the area so it slides easier. Rubbing soap or wax on the sticking area will often help.
