- Are there any warning signs of mould to look for in my commercial facility?
- What is that smell?
- How does mould spread?
If there are dark spots on your ceiling, floors or walls, this is a sure sign of mould growth. Musty odours and mildew are often also signs that mould may be growing in your property. Respiratory and allergy symptoms such as coughing, sneezing, trouble breathing and wheezing are a common indicator of mould growth as well. High humidity levels in your building that result in condensation on glass and metal surfaces are also a warning sign of mould.
Usually, if it smells like mould, it is mould. Mould or mildew odours are due to the presence of fungi in the air, inside pipes or walls, or hidden in other parts of your commercial property. Mould is thicker than mildew, so if the smell is particularly strong, that’s a clue that it’s mould and you need to act fast to prevent further growth.
For moulds to grow and reproduce, they need a damp environment and an organic food source, such as cellulose, which is found in many building materials such as wood, drywall, ceiling tiles, and other household materials such as carpeting and fabrics. Mould can also grow in the HVAC system, roof, foundation, and other areas where the environment encourages mould growth.
