Mold consists of microscopic fungi that generally develop on putrescible or dusty surfaces when there is a presence of water, however small. When it becomes visible, mold appears in our homes as black, white or colored spots on materials such as wood, plasterboard, fabrics and wherever dust accumulates.

The whole thing is usually accompanied by a typical odor associated with the presence of excessive moisture. Depending on its type and magnitude, it is common knowledge that the appearance of mold inside our homes and other buildings can result in occupant health hazards.

For mold to develop on them, the affected elements must be in contact with water for a sufficiently long period. The causes of this presence of water can be numerous: a water infiltration coming from the outside, a leakage of water somewhere inside, the formation of condensation, displacement by capillarity, etc.

Although only the microbial analysis of a sample taken from a contaminated surface can confirm the presence of the mold and its toxicity, any visible traces or odors should be considered important and be treated immediately. If the area affected is small, it is recommended to thoroughly clean the affected areas with soapy water to remove the traces. Avoid the situation from recurring by ensuring that you always keep the area dry and well ventilated.

Since mold can be caused by a variety of problems, if mold is present in your home or even if you only suspect it, it is strongly recommended that you consult one of our experts to determine the magnitude of the situation, its actual causes and the corrective work and decontamination interventions needed.
