When I moved into my flat at the end of January I noticed that the front door (external to fresh air, not leading to corridor or anything) closed snugly but was fine. There was evidence that it had been planed down to fit at the opening edge. During the summer it appeared to "shrink back" so that by the Autumn there was a gap of nearly 1cm for wind to whistle through. During the last few weeks though (I think it started around the frosty days we had in the South East) the door has now swollen so much that it's really hard to open and shut. So much so that I can see a time when I won't be able to go out because I won't be able to shut the door behind me!
I don't want to plane any more off because drafts will get worse in the Autumn again. Any suggestions?
