Mould comes in a variety of colours and genus depending upon the growing conditions and the food source. Mould is a natural part of the environment; only when the concentrations get high (above normal outdoor levels) do you need to be concerned. Numerous building materials and finishes provide an excellent source of food. Add moisture and warm temperatures…voila, mould!
Spore + water + food source + temperature + time
Here are brief descriptions of several common moulds you might find in your home or business. You can find more detailed information from many other sources, but not all agree on their health concerns. Also contact Advanced Remediation Solutions about black mould removal in Edmonton.
