It is of the utmost importance that suspected damp in walls be treated as quickly and as thoroughly as possible. Quite often condensation on the opposite side of the wall is responsible for the build-up of mould as well as a number of similar problems of a serious nature. Many of these damp problems can weaken or destroy the construction elements in your wall which will eventually lead to you having to replace some or all of these construction elements. Conditions such as mould and related spores are also unhealthy.
If you understand the causes of how damp happens then the treatment becomes quite simple and there are a number of products that allow you to treat damp and condensation yourself and also allow you to put preventative measures in place to combat future re-occurrences. Before any of this can take place however you need to fully understand all the possible causes of damp in walls and how to go about treating them effectively. A mistake that many home owners make is to simply treat the visible mould or paint over the damp area without knowing how to treat the root cause of the damp. This is not a good idea because if you fail to eliminate the root cause all you will end up doing is treating the symptoms over and over.
Condensation is one of the main causes of damp in walls. Condensation is a change of the moisture content in the air, moisture turns to water droplets, often on the external walls but it can also occur on the internal walls as well. The reason for this is usually that the air is warm and the wall is cold, similar to what happens to a cold glass bottle if it is sitting in warm air for a while. Most incidents of damp occur in basement areas or areas where the walls are typically colder than the surrounding air.
Other common causes of damp in walls is internal pipes that leak or in their own way cause condensation effects because most often pipes are also colder than the air around them and in this way internal pipes contribute to the damp in walls.
