Rising damp occurs when excessive moisture from the bottom absorbs up into porous building materials such as natural stone, brick, globe, mortar and into the composition of the building. The moisture content evaporates from either face of the wall membrane, allowing more to be attracted from below. Rising wet is common in aged structures, but can also appear in newer structures if your damp-proof course has been damaged.

If you do not notice tide marks, another frequent let tale sign is damp areas or staining. usually, these wet patches are yellowish to dark brown in coloring and a lot like tide marks, you will observe them again up to 1 metre above the skirting mother board.
If you’ve seen wallpaper arriving off or peeling from the wall membrane there could be a damp issue. Usually the wallpaper begins approaching loose from the skirting panel first, and the part of the wallpaper may be curved up.
DECAYED SKIRTING BOARDS
Much like many varieties of dampness, rising wet has the potential to cause rot within timbers it makes contact with. Consider skirtings that are damaged, easily crumble or localised fungus growing on or creeping out of the side. Also, consider destroyed or flaky paint.
SALTS INSIDE THE PLASTER

When you have wallpaper on your wall surfaces, you may listen to a suspicious ‘crunching’ sound – this is the salts that contain been used from the bottom. Then when possible, go through the open surface of the brick or natural stone work. Check to see if there are any salts developing and whether the brick is in fact wet.
Additionally it is important to notice that rising wet only occurs on surface floor levels as it is moisture from the dirt that has been drawn up the walls and therefore causing the growing damp problem.
If your wet problem is on the first floor or above, you may simply just have a condensation problem or a penetrating wet issue.
