If you believe that you may have mould present in your home or business, it is important that you seek professional mould removal in Toronto as quickly as possible. Mould can grow on almost any surface as long as there is moisture and oxygen present. When mould grows, it produces small seeds known as spores. Although these spores are invisible to the naked eye, they continually float through the air. Whenever there is excess moisture present, the mould spores floating through the air continue to grow.
