Rising Damp

What is rising damp?

Rising damp is simply water from the ground that rises through the bricks of a wall. It is most often caused by a breakdown of an old damp proof course, or the lack of one altogether. It can happen on any wall (internal or external) that is build into the ground on a foundation.

How to spot rising damp

Rising damp will generally appear along the base of a wall and there are a number of signs to look out for including:

  • Damp or decayed skirting boards
  • Salt stained plaster
  • Discolouration and staining at the base of a wall
  • Peeling paint or wallpaper

How to treat Rising Damp

Rising damp is commonly misdiagnosed, so we will use a moisture meter to build up an accurate moisture profile of the wall as well as salt analysis if required. We combine this with our knowledge and experience to form an accurate diagnosis. 

Once the diagnosis is confirmed, we will use the most suitable modern suitable damp proof system to rectify the problem. One of the most common methods is to remove wall plaster (usually around 1.1m high), and inject a chemical damp proof course into the wall to form a damp proof course. We will then apply a specialist waterproof plastering system to protect the wall from further potential damage.

If you suspect that your property may be suffering from rising damp, contact us today and we’ll arrange to come out and take a look. 

Every property we look at we always take the approach “what would I do, if it was my home?”. If there are alternative options to carrying out the works, we will always make this clear to you. In 2018, we did not recommend works on over 20% of the surveys we carried out.
