Mould spots in the house are bad for your health

Mould in the home can have major consequences for health. An air humidity value between 40% to 50% is beneficial for creating and maintaining a healthy living environment. High humidity has a negative influence on our airways and increases the risk of developing allergies and the growth of mould, Bacteria and transmission of viruses. When the air humidity is higher than 70%. House dust mite grows faster and humidity exceeding 80%. there is a greater chance of the growth of moulds and the release of toxic substances from building materials. Therefore, do not delay in calling in a damp control specialist to survey your property
