When we have heavy driving rains it causes the front door to expand and we're unable to close or lock the door until it has dried out and contracted. There is no veranda so the rain hits straight onto the front door.

How can I prevent this?

  • Would you consider mounting some sort of roof (there are simple aluminum sheet kits out there) over the doorway? Jul 21 '16 at 14:40

I am going to guess that you have a wood door causing the problem. If you have checked the original installation and frame alignment and feel that cannot be changed, then the only real solution is to plane it down so it closes properly when damp or humid. You can install extra or new weatherstripping to assure it has a good airtight seal,especially in dryer times when it may shrink a bit.

    Don't forget to seal the edges after planing. Jul 21 '16 at 13:22

    For that matter, seal the entire door, front, back, and edges. Jul 21 '16 at 14:39
  • A marine grade spar urethane such as the type used on wooden boats will go a long way to help protect your door from the elements. Make sure to have a liberal amount of finish applied to all 6 sides of the door. If the door binds at the bottom, a good way to fix that is to trim the bottom of the door, and install a bottom weatherstrip. This will allow the door to expand and contract without leaving a gap.

I would install an awning or porch roof extension out 3 feet from the building wall line to protect the door.

They even make fabric type awnings that can roll up against the wall during nice weather times.


You might consider replacing the wooden door with a fiberglass one. Metal would avoid the swelling issue, but likely suffer from rust/oxidation due to the wet environment.

  1. Cover the entry with a roof, awning, etc.
  2. Wait until the door is dry and seal it with many layers of Tung oil, shellac, Varathane, or even a high quality paint (epoxy? or oil based paint)
  3. If the door opens inward, add an exterior water resistant door like a conventional screen door but which has windows in areas where the water strikes.
