4 signs your home needs rising damp treatment
Rising damp occurs when the masonry structure of a property has been left unprotected and a damp proof course has either not been installed or is defective. Without effective treatment, rising damp will continue to get worse.
There are several types of damp problem, so our damp proofing experts have put together a guide to help you spot the signs of rising damp in your home.
Signs of rising damp to look out for:
1) Distinctive damp patches
Rising damp starts at the floor or skirting board and rises upwards, leaving visible tide marks on both the exterior and interior wall. You may also see patches of mould and deposits of salt left behind by groundwater that has evaporated. Often, you will notice a musty or damp smell.
2) Damp patches are no more than 1.5m high
Rising damp is caused by groundwater travelling through the bricks and mortar of a property via capillary action as it seeks a means of evaporation. The damp will rise until no further evaporation is possible and gravity stops it from going any higher. This is typically when it reaches a height of 1.5m.
3) Damp is only affecting the ground floor
4) Damage to the affected area
Areas that are affected by damp may start to show signs of damage. This includes crumbling or rotting skirting boards, as well as blistering and peeling wallpaper.
How do you treat rising damp?
The first course of action is to remove the contaminated plaster before injecting a specialist damp proof course. This will create a tight, water-resistant protective band through the thickness and length of the wall. Once this is complete, the affected walls will need to be replastered using a cement render with salt-inhibiting and waterproofing additives.
