Rising damp is common in Australian homes and may cause these problems:  

  • brickwork fretting (wear)
  • timber rot
  • mould
  • rust in reo (concrete cancer)
  • render popping
  • paint bubbling
  • and more …

All of those problems are expensive to fix in terms of your time, stress and finances.

Rising damp is not only bad for your budget, it also has potentially serious health effects

What causes rising damp?

Masonry or brickwork, the outer skin of many brick veneer or full brick Australian homes, has an ability to draw moisture up from the ground, past the floor level and to the inside of the building, much like a straw, affecting the house.

In older buildings the damp proof course breaks down or perhaps was never installed, allowing moisture to be drawn up, carrying ground salts which is build up in the wall until render, paint, plaster or similar peel or bubble off.

By this stage it can be seen from inside the building that there is a problem.

This hydroscopic action is more powerful than any temporary mask, such as repainting, that you may put over the problem. Repainting may seem to work for a while, but it will eventually fail again!


What my building inspections reveal about rising damp

I inspect a lot of houses and I have come to realise over the years that many builders seem to think that rising damp is not much of a problem. However, what I have discovered is that when a wall affected by rising damp joins onto other walls during renovations, quite often the builder or home owner calls me in to investigate and it turns out that it is always the older walls, affected by rising damp, that are causing the problem.

How does damp proof coursing help?

Damp proof coursing makes the course (row of bricks) damp proof by placing a barrier when moisture is drawn up. The upward movement of moisture stops when it hits the barrier and tindependent building inspectors discover rising damp again - imagehe brickwork is not able to draw the moisture higher, so moisture exits the wall and is confined below living areas, preventing all the nasty conditions mentioned above.

Fixing rising damp can be expensive …
