We have a very difficult wall with numerous damp issues. Threre numerous brown and grey wet spots showing in the house and paint and plaster gets cracked in places. There is also water dripping out of door frame and a window frame where water has gone into the cavity.
It's a cavity wall and there is some insulation material in it like fibre glass (there are lot of botched up jobs here). Nobody know how old this wall is - it may a 100 years old or a few decades.
This is what we have done so far:
- filled in all the tiny cracks in the render with some caul
- new chimney capping and flashing
- new roof
- new gable line (the roofer left some gaps there)
- ditch next to the house to guide the water away
- conservatory fitting to the house completely redone (that seems to be fixed now - no more water coming into the conservatory)
BUT when there is a strong storm there are still new damp patches on the inside wall of the house - mostly upstairs and water dripping from the door frame.
We have been told by the builder to cover the whole wall with something like dulux weathershield.
What are your opinions?
