French doors will not close
French doors are a popular choice as a secondary entrance point invariably to a garden. As a result, they get lower usage, sometimes remaining unopened in the winter months but when spring comes issues with water ingress, material expansion and low maintenance can result in them becoming difficult to open or close. Issues with French doors tend to arise when one of the doors moves slightly which puts it out of true with the other causing both doors to become difficult to open. Isolating which door is the culprit is always a good starting point.
