Hi all, I have a persimmon house that was built in 2002. I have recently had water ingress into one of my bedrooms. The bedroom is built against an outside wall and is part of the original house. The leak looks to have been caused by the external skin bricks being porous and potentially cavity trays not being fitted.
My builder needs to complete some investigation work on whether cavity trays are fitted, but my question is this: Were cavity trays a building regulation requirement in 2002 for rooms that abut an external wall? I’m trying to find this out so I can take potential legal action against the builder if the cavity trays have been omitted.
Any help/advice would be greatly appreciated.
