When we added the bilco door to the basement/crawl space to the camp, I had to make a door to fit. I used double thickness 1x6 pine and made a double Z door design. I stained the door, but apparently it wasn't enough to stop it from swelling in time of high moisture in the basement (early spring and recently because of the rain and increased moisture in the basement). My question is, would I be improving the situation by removing the door, bring it to a dry environment, trim it, then paint it with an oil based paint? I really didn't want to get into a custom metal door cost. Looking for any suggestions.
