Not sure if this is the right forum but will ask anyway. We have damp climbing the walls in our kitchen doorway. Seems to be a recent development and is likely to be due to the sealant at the bottom and corner of the UPVC door perishing.
IF this is the case I'm assuming I can just reseal with something but not sure what I should use as if it rains whatever I use is going to struggle to cure in the first place.
Any ideas?
