Mould growing on walls on many occasions is caused by excessive moisture caused by condensation Warm air can hold more moisture than cold air. If air is warm enough to store a considerable amount of moisture and if the air is cooled below dewpoint, relative humidity exceeds 100% and condensation occurs.
Condensation can occur where moisture levels are too high. Water vapours from a source to an area of cold temperature. Temperatures in the building fabric are too low. Dampness in buildings will increase the humidity level within a basement and building contributing to condensation occurring. Condensation can cause mould growth in buildings and houses. Pro Team Group have solutions for stopping condensation.
