My windowsill is getting damp on one side of the window, the window fitters knocked a hole in the reveal to get a better look and concluded the uPVC frame isn't leaking.
I have an endoscopic camera which I've been able to shove up there and find out that the rain water is getting on to the DPC and dripping on to the small bit of sill that protrudes in to the wall.
On the outside I think a small piece of DPC can be seen in the top corner of the window, but as it's wet and windy I can't get a proper look.
Could that be causing the issue?
