Ventilation is the process of supplying and removing air by natural or mechanical means to and from any space. Ventilation creates a positive flow of air that allows the dwelling to “breathe” which helps prevent moisture build-up all year round. The air inside a room should be circulated with the air outside.

When people or animals are present, ventilation is especially necessary to remove carbon dioxide and renew the oxygen used. It also aids in the removal of stale odours caused by smoking, painting and cooking, etc. A lack of ventilation can lead to many health problems especially those who suffer from allergies, asthma, sinusitis, and breathing disorders.

Generally in the Winter months there is a significant rise in ventilation problems. These problems are caused by the use of constant heating devices where the windows are kept closed to keep the cold air out. Of course we are going to keep our windows closed in winter. But when condensation occurs and their is a lack of air circulation, it creates the perfect growth conditions for mould and mildew.

Signs of mould and mildew will be found on many items such as windows, leather items, furniture, articles of clothing and bedding, reading materials, bathrooms and artifacts. Within a couple of colder months, some of these items will be destroyed with the attack of such fungus. Mould and mildew lead to musty odours, allergies, smelly basements, ruined textiles, damaged artifacts and reading material. These signs all indicate to a lack of ventilation.
