Fungus is of two types. The single-celled ones are known as yeast and the multi-celled varieties are known as mould. Moulds are most popularly seen to grow on food items as they have intrinsic moisture within them. This moisture is food for the moulds and helps them grow ending up spoiling them. Besides food, moulds also grow on buildings if the structures have been attacked by moisture. Thus, monsoons form the peak season for growth of moulds on buildings.
On buildings, moulds grow both in widely visible areas, like damp areas on walls and roofs, as well as in hidden areas, like damp patches underneath carpets or behind wallpapers, and inside floor or ceiling tiles. Commonly, visible mould occurs both inside and outside a building. But, hidden mould normally occurs inside the building and is thus classified as indoor mould. Removing any mould growth is imperative and should be done by professional cleaners, especially if the mould growth has assumed significant proportions or may even remove them if growth has reached greater proportions and then carry out treatments so that the fungi or even dust contaminated with fungi may not enter into the unaffected areas. This entire procedure does not only clean existing fungi but also ensures that fungal growth does not relapse.
Removing small mould growths can be effectively done with simple detergent wipes over affected areas. This typically does not require professional intervention. The common professional methods of removing significant mould growth are Dry Brushing, used to remove fungi from solid wood surfaces, Dry Ice Blasting, used to remove mould from wood and cement and, Wet Vacuum, used to remove mould from wet surfaces. If none of these methods is effective, then the affected areas are removed altogether. Once this cleaning or removal processes are done, a High Efficiency Particulate Air vacuum or the HEPA vacuum is used to clean the surrounding air of all contaminated dust and debris. This prevents further contamination of unaffected areas. A reputed professional mould removal service is the best bet to remove mould with the most effective techniques.
There are specialised equipment and tools used for these types of professional removal of fungi. Moisture meters and humidity gauges are used to measure the level of moisture affecting the affected portion of the structure. Borescopes, that is, cameras attached to the end of flexible rods, are used to detect hidden growth of mould. Thermographic cameras use infrared thermal imaging to identify secondary sources of growth and helps in taking precautions against further contamination. Personal protective gear includes eye protectors, respirators, gloves and impervious suits.
