Fresh, clean and healthy indoor air is important for your health since you can breathe easily and you will not be exposed to respiratory infections. However, a damp home is dangerous to your health and it can cause structural damage which can be costly to repair.

A damp home will always have a musty smell and will normally feel chilly due to the moist walls and floors. The home can become damp due to condensation when moisture in the home is not properly channeled to the outside. Rising damp is also a cause of a damp home especially for older houses.

How Rising Damp Takes Place

Rising damp is as a result of moisture which rises from the ground by passing through tiny openings found in brick walls or masonry. The water can rise up to over a meter up the wall and is easily absorbed by the plaster found in internal walls. The lower part of the wall will normally be cold and will have white powdery stains from salt deposits. Ground water contains dissolved salts which are left on the wall surface once the water evaporates. These salts absorb moisture from the air causing the wall to remain wet throughout.

What Causes Rising Damp?

You can know you have a rising damp problem once you notice staining on the lower part of your wall near the skirting board. Your floor boards and skirting boards will begin to rot and plastering may have fluffy salt deposits which come from the wall. Your walls may also have mold stains which normally appear as dark spots. Rising damp happens when the home does not have a damp proof course or if it has one that is not effective.

A damp proof course can become ineffective due to aging or if it was not properly installed. The damp proof course is made up of a water resistant membrane which is placed near the concrete floor on the internal wall or under a raised timber floor. This membrane prevents water from rising up the building.

Other Causes Of Rising Damp

If your DPC is in good condition and you are still experiencing rising damp, it is important to check the ground that is next to your external wall. It could be that the ground level next to the external wall has been raised above the level of the DPC thus enabling water to continue rising up the wall. It could also be that a driveway or stairway has been constructed outside the building and is soaking in water which then moves to the building.

The Role Of An Expert

The source of rising damp in a building can easily be misdiagnosed and you, therefore, need to call in an experienced expert. The expert will be able to identify the source of the rising damp and recommend a method that will immediately stop the moisture from rising up the building. The expert will confirm that the building has a DPC which is normally visible as a line at least six inches above the ground. He will ensure that the level of the ground next to the external wall is not above the DPC and if it is, action will be taken to lower this level.
