Rising damp is what you’d expect from the description: moisture rising up brick or masonry walls from the ground.  Your wall can act a bit like a sponge when this happens. The sign you need to look out for is a stain that looks like a tidemark on your wall, usually lower down. If you see this tide mark and sometimes salt deposits on the wall, you might have a rising damp problem that needs taking care of. Our Qualified surveyor will carry out an in-depth survey to find the cause of the problem and recommend any treatments required in a detailed report .
