Unmasking Rising Damp: A Comprehensive Guide to Identification, Impact, and Intervention
Understanding Rising Damp
Rising damp is a common issue that plagues many properties in the UK. It is a condition caused by ground water moving up through a wall or floor. Most houses have a barrier installed at the base of the wall (damp-proof course) to prevent this, but these can fail, or, in older properties, may not even exist.
Rising damp can be a serious problem, leading to structural damage and health issues for the occupants. It can cause the decay of timber floors and skirting boards, damage to plaster and paint, and encourage the growth of mould.
Identifying Rising Damp
Identifying rising damp can be tricky as it often gets confused with other types of dampness like condensation or penetrating damp. However, there are certain signs that can indicate the presence of rising damp in your property.
The most common signs include damp or wet patches appearing on walls, usually up to 1 metre above the skirting board. Other signs include wallpaper peeling away, a damp musty smell, discolouration and staining of wall coverings, and the appearance of a white, powdery substance on your walls.
Active Vs. Historic Rising Damp
It’s important to distinguish between active and historic rising damp. Active rising damp is currently happening and causing ongoing damage to the property. Historic rising damp, on the other hand, has occurred in the past but is no longer active.
Active rising damp will continue to cause damage until it is treated. Historic rising damp, while it may have caused damage that needs repairing, is not currently causing further harm.
Properties Most Affected by Rising Damp
Rising damp is more common in older properties, particularly those built before the 20th century when damp-proof courses were not commonly used. However, it can also affect newer properties if the damp-proof course has been bridged or is faulty.
Properties located in areas with high groundwater levels or those built with certain types of brick or stone that are more porous can also be more susceptible to rising damp.
Dealing with Rising Damp
The first step in dealing with rising damp is to confirm its presence. This can be done through a professional damp survey. Once confirmed, the best course of action is to seek professional help to treat it.
Treatment for rising damp usually involves removing the affected plaster, installing a new damp-proof course and then replastering and redecorating the wall. In some cases, it may be necessary to replace decayed timber floors.
Preventing Rising Damp
Prevention is always better than cure. Ensuring your property has a functioning damp-proof course is the best way to prevent rising damp. Regular maintenance checks can also help catch any potential issues early before they become a major problem.
