Do you have white stains on your external wall?

Do you see a whitewash type of stain on the outside wall of your house? This not only unattractive, but can also cause permanent damage to the house. Nobody wants this, so it is therefore important to take immediate action as soon as you see that there is a damp problem. White spots on the outside wall can have several causes and requires a permanent solution to prevent damage to the house.

What is that white stain on my external wall?

A white stain on an external wall happens when salts are pulled out of the bricks by moisture. This is therefore a damp problem in the wall. This can be caused by various types of damp, rising damp being one of the common reasons. Many people confuse this with a mould problem, but it is specifically a damp problem. Another problem which can cause white stains on the wall is limescale. This is when the lime runs out of the bricks to the outside wall of the house. This can sometimes be washed away by the rain, but it can also penetrate the outside wall. When this happens, there is a good chance that the stain on the external wall will get worse.
