I've noticed thin cracks becoming visible on multiple door and window frames where the horizontal and vertical wood of the frames join (on the corners.)
It appears they were just painted over and they are all reappearing. I also noticed 2 of the doors have become harder to open/close in the last few weeks. Moved into the house in the summer and this began in the winter.
Could it be weather related?
We've discovered other evidence of shoddy work by the developers so I'm concerned this may be a sign of something much more serious.
