Hi.I'm a young builder and dealing with a damp issue thats bigger than I have ever delt with before. I am currently working on a renovation for a family member.
The house has had roofing issues, no windows and broken guttering which has been rectified. All old lime plaster and rotted joists have been replaced but the bricks are still soaking wet,I still am yet to repoint the soft damaged mortar above damp course and have large amounts of salt deposit's over a 2 meter stretch underneath the floorboards below damp coures. I have come to the assumption that water was coming down from the leaking gutter,broken window and a leaking flatroof. My question is do I need to use anything on the brickwork to seal them after removing the salt. Also as this is a 9" brick wall with no cavity and is extremely uneven what's the best way of replacing the plaster? I was thinking of using a vapour barrier and stud wall. About 50mm off the brickwork. Would I also need to insulate this new cavity. Thanks for any advice.
