What is Rising Damp?
Rising damp is a building defect caused by ground moisture travelling upwards through porous masonry materials such as brick, mortar, and stone. This natural process, known as capillary action, allows water from the soil to rise through walls when there is no effective damp-proof course (DPC) in place — or when the DPC has deteriorated or been bridged over time.
This form of damp typically affects ground floor walls and can lead to long-term issues such as damaged plasterwork, staining, efflorescence (salt deposits), and even rot in timber floors or skirting boards. Rising damp is often misdiagnosed, making a professional rising damp survey essential for proper treatment.
It is especially common in older UK properties built before the early 20th century, many of which lack modern damp-proofing systems. However, modern homes can also be affected due to poor maintenance or structural changes that compromise the existing DPC.

What Causes Rising Damp?
Rising Damp is caused by water from the ground being drawn up through the permeable wall structure, also known as Capillary Action.
There are several factors contributing to rising damp; Absence or Damage to DPC which is common in older buildings. High groundwater levels in the area causing poor drainage, where water brings salts and minerals from the ground, the moisture then deposits these salts as it evaporates from the surface of the walls, leading to decorative spoiling. And poor property maintenance (cracks in walls, floors, or blocked drainage systems), allowing moisture to seep in.
