So the front door (ancient timber one) is sticking a bit at the bottom, directly below the latch. Perfectly possible to open it without problem if you apply a bit of lift to the handle when you pull, but you know what SWMBO and kids are like.
Something Must Be Done.
I am very loathe to take a plane to it, as I'm sure it's a weather thing (has happened before) and the timber will shrink back again leaving too large a gap. (Have had this experience before and consequently the French windows spend all the winter with a large strip of duck tape down the middle due to the massive gap between the doors).
How is it best to handle a problem like this?
