Things You Will Need
The solutions are uncomplicated and can be completed with everyday household tools.
-
Inspect all the screws and hinges in your french doors. They tend to loosen over time and the solution may be as simple as tightening the screws to hold the doors correctly in the frame. Use a Phillips or flat-head screwdriver to adjust the screws. Whether you have french doors where one is stationary or both of them swing open, it is important to adjust both doors if necessary.
-
Check the door knobs and locks to ensure they are tight. If not, tighten them with a screwdriver. Hinges or knobs that are not tight enough causes sagging, thus making the french doors stick.
-
Enlarge the opening of your french doors by hammering a couple of nails into the door frame and the studs below them. This causes the frame to hold together more efficiently. Even adjusting the frame 1/16 inch may prevent the french doors from sticking. Determine where the door is sticking and hammer a 2-inch or 3-inch nail into that area and 6 to 12 inches above or below it to solve the problem.
-
Tape pieces of carbon or another type of paper that leaves a blue or black impression to the area of the french doors where you suspect they stick. Open and shut the doors a couple of times and sand down the areas with the markings by using a plane or sandpaper to smooth and adjust the surface.
