While molds and mold spores are generally innocuous by nature, they pose a health hazard when these are found in large quantities and in damp and moist environments. If left unchecked for prolonged periods of time, these may cause allergies (such as asthma and skin irritation) and respiratory problems (such as nasal congestion and throat irritation). In some cases, neurological problems and death may result. To address this, RAS determines the source of the dampness and moisture. Solutions include non-intrusive and intrusive methods and recommending appropriate building materials.
