- PossibleShed frame settling or racking out of squareSheds on unlevel ground can shift slightly, throwing off door alignment.
- PossibleSwollen wood door or frame from moistureWood shed doors can swell in humid conditions similar to house doors.
What to do
- For sliding doors, check if rollers have come off the track and reseat them, cleaning the track of debris.
- For swing doors, tighten all hinge screws, and if holes are stripped, fill with wood filler and re-drill.
- Check that the shed is sitting level; a significant lean can be improved with shims under the low corner.
- For wood doors swollen shut, sand the sticking edges lightly once conditions are dry.
- Lubricate tracks and hinges with a dry lubricant once mechanical adjustments are made.
- For a persistently out-of-square frame, add a diagonal brace to the shed's frame to stabilize it.
Tools and parts
- Screwdriver or drill
- Level
- Sandpaper (if wood swollen)
