Hi, I have had this damp patch on the kitchen wall (outside cavity wall) since February this year, it has grown in size very slowly. So far I have had a builder out who suggested its the missing mortar from the outside brickwork so he re pointed an area directly above and around it. I hoovered the bubbled paintwork off and drew a line around it but it continued to grow/bubble moving towards the window. I asked a 'handyman' to help and he said as the bath runs along the wall directly above that it could be the sealant, so I had it resealed about 2 months ago but it is still bubbling the paintwork each time I hoover it off. There are no stains or patches on the ceiling. Could anyone advise please what type of trades person would be able to assist or what type of damp this is. Many Thanks.
Hi dollyd Looks like there is some rubble bridging the cavity. Bricks need to be cut out on the outside, debris cleared and bricks replaced. This can be done very neatly using an arbotech saw and the original bricks can be mortared back. Some builders should be able to do this for you. Regards S
Thank you Stoneyboy, Would that be the case so high up on he wall? The patch is just a few inches from the ceiling? Would you get a plumber to check under bath/pipes etc first or just go straight for the builder? Thanks DollyD
