Sources of Moisture Above Ground Level

During our survey it is important to establish all sources of moisture within the building. This can come from a variety of sources, and will be covered within our Report/Quotation under Observations both externally and internally:

Condensation – Surface condensation occurs when the temperature of a material falls below the dew point. Where the air reaches a Relative Humidity of 100% it will allow water vapour to change to a liquid and free water will be deposited as condensation. It is important to note that Relative Humidity is a “Proportion” not an amount. The term Relative Humidity refers to the amount of water vapour in the air at any given temperature, expressed as a percentage of the maximum amount of water that can be resident at the same temperature.
