Common tell-tale signs of rising damp:
Tide marks and damp staining.
Tide marks are caused by evaporation and salts from the ground.
You will normally notice them anywhere up to a 1 metre above the skirting board.
If you do not notice tide marks, another very common tell-tale sign is damp patches or staining.
Typically, these damp patches are yellowish or brownish in colour and similar to tide marks.
Look out for wallpaper coming off or peeling away from the wall. You will most likely notice it coming loose from where it meets the skirting board first with the corner of the wallpaper turned or curved up.
Decayed skirting boards.
As with many forms of dampness, rising damp has the potential to cause rot within timbers it comes into contact with.
Look out for skirting’s that are cracked, easily crumble or localised fungus growing on or creeping out of the side. Also, look out for damaged or flaky paint.
