The problem of sticky doors and windows often develops when mobile homes have settled unevenly. Before you try repairs, verify both longitudinal and lateral leveling of your home with a carpenter’s level (page 20). Make any necessary adjustments in the blocking.
Inspect the doors again. Leveling may have corrected some of the problems or it may have created new ones. Open and close all the doors several times. For those which do not close easily, hunt for the cause of the sticking. First try lubricating the hinges; an aerosol will do, with silicone lubricant.
Then look for bent hinges. You can either remove them and try to hammer them straight, or use the old hinge as a template to help you buy new ones.
Stress on the hinges may have stripped the wood that holds the screws. Fill the holes with small pieces of wood such as kitchen matches. Better yet, fill the holes with wood putty. Then reseat the hinge screws.
If you find no fault with hinges, inspect the door itself. You may be able to cure rubs at the top of the door by prying downward with a piece of wood, a hammer, or a broom handle. This warps the hinges, but sometimes that saves a lot of time in sanding. You can use a similar ploy to fix some cases of faulty alignment. Slide something firm but soft (like a man’s wallet) between door and frame near the top or bottom hinge. Try to close the door. Don’t force it shut completely, only enough to spring the hinge. To close a gap on the hinge side of the door, tap the open edge with a hammer.
Beyond these quick-repair hints, the job becomes a carpenter’s problem. With metal doors, rehanging a misaligned door involves shimming up under the hinges. Again, you’d probably do well to hire an expert rather than trying to do this yourself. If you leave the fault go, however, it only grows worse and eventually may ruin the door frame.
