Sorry if this is an obvious question.
Can anyone tell me why the dry lined plaster in our house so frequently cracks beneath the edge of the windows?
At first I thought it may be relating to the heat changes or something over time; however, we've recently had a room stripped down, new plasterboard put in and it's been re-skimmed, and three weeks later, it's cracked just beneath the edge of the window.
The cracks are barely visible, and don't seem to get any worse over time - they just crack and stay cracked.
