Hi I need some help please
About a month ago I asked for some advice on why I was getting water marks on my plasterboard above bifold door (not huge amounts).
I was advised on this forum to check the cavity tray and it hasn’t been installed on this south facing wall but a dpc was used above lintel. I’ve asked some cavity trays to be fitted only to find when I’ve got up on ladder on one side of the tray at the back there is a considerable gap 5-7cm where the back bit almost rests on the Inner brick. Builder says this should be ok as my wall isn’t straight so bit of a gap at the back my concern is before it’s all Bricked back up would this allow water to penetrate through inner leaf ..
He’s suggested trying to bridge that gap from the top of cavity tray with some kind of easy lead so it adheres to wall?
Any suggestions would be good as he’s back tmrw.
Also pls advise things I need to look out for with cavity tray
As I don’t really want to open up the bricks again
Thanks
