If you build a wall in the oceanfront, you will observe certain tidemarks after some time. The tidemarks show the maximum the ocean water has hit. When it comes to rising damp problem, it is the same scenario. The tide mark will indicate the level that the damp has gone upwards. Water especially from the ground has salts. When the water percolates through the walls upwards, the moisture content will evaporate leaving the salts. Salts will then appear as patches creating some visible evidence of rising damp. The tidemarks will tend to appear within the range of 1meter above the ground level.

Wallpapers peeling off

Wallpapers are held in position by the adhesives. If the adhesive gets compromised, then the wallpapers have no option but to come out helplessly. Rising damp can get to extreme levels climbing up higher than the expected 1 meter. If this happens, the wallpapers will start coming off initially from below until the top areas are affected.

Withering skirting boards

Ever wondered why skirting is necessary? Well, skirting helps to seal the house. The water from the ground will not be able to penetrate to the ground floor. However, that does not apply to all types of skirting. Where timber skirting is used for example, the purpose is more of aesthetics. That said, the timber boards down there may not be able to resist the damp environments. The end result is the timber decaying and easily crumbling not forgetting of mold growth. The paint on them will also come off.

Black mold

Mold is a general sign of all types of damp problems including severe penetrating damp. However, focus on where the molds are growing. This time, you need not focus on the ceiling or the cornice corners. The area just above the skirting and within the skirting boards themselves should tell you more. If you detect mold growth, then water must have crossed the border from the underground wall to the superstructure wall.

Salty plasters should also indicate raising damp. Make sure you act first if you detect any of these signs.
