I have a victorian property which like most has joists that run into the walls and are supported on the wooden wall plate. This is however rotten! What is the best was to replace this? The joist ends are also rotten. Is it best to hack out the wall plate and attempt to install a dpc and brick it up and then use joist hangers? or is it best to put wood back in. It has solid walls and the bricks are very porous so the walls are damp throught the property. The back of the property has been rendered now and the sides and front will be sprayed with brick sealant so hopefully this will resolve this issue. Under the floor is quite damp there is good ventilation down there though. Any ideas an all of this?? The sleeper wall in the middle of the room seems ok as does the plate on here.
