Dampness can be a problem in any building, and it can be difficult to know how to treat it effectively. It can cause a range of health problems, including allergies, asthma and other respiratory issues.
The first step is to identify the source of the dampness. It could come from a number of places, such as a leaky roof, poor ventilation or rising groundwater. Once the source has been identified, it can be treated and the dampness eliminated.
The acceptable level of dampness in a building is 70% relative humidity (RH). This means that the air in the building contains 70% of the water it can hold at that temperature.
If the humidity level in your building is consistently above 70%, it is considered to be damp. This can be a problem, as it can lead to the growth of mold and mildew. Mold and mildew can cause a range of health problems, including allergies, asthma and other respiratory issues.
