Hi @Rennie, welcome to the Mr Damp platform!
Thank you for sharing your image and bringing attention to the issue of water ingress. Your update is spot on – water ingress can indeed lead to dry rot and damp plaster, which can be a real headache for homeowners.

Your image is quite informative and shows the extent of the water damage. It’s essential to address this problem as soon as possible to prevent further damage and potential health risks from mould growth.

We are always open to offering advice on any issues you may have also!

Welcome and have a great day
Mr Damp

Your 100% right Rennie, I find that external defects are a major cause of internal damp and timber issues rather than the problem always being diagnosed as rising damp. 👍
