As I type I have water dripping onto my kitchen window ledge from around the top edge of a uPVC window.
We thought we had resolved this problem having found a crack in the render, sealed it, and a crack in the mastic around the window and sealed that. Apparently not.
The render is not "blown" from the wall as far as I can tell (not hollow sounding when tapped).
There is a window directly above the one with the leak (on the floor above) and that has no problem.
The wall around the leaking window is damp/mouldy (been leaking for some time without being noticed too much I suspect and now got worse).
Can anyone advise me ...
a) What might be the cause
b) What sort of skill I should look for to come and help me identify and fix the problem (renderer, builder, bricky, etc)
Thanks in advance
