How does mould live and exist?
There is always a “food source” available for mould in the indoor environment. Mould feeds on many building materials such as wallpaper, paint, carpet, woods and other organic materials. You have probably seen mould growing on the tiles in your shower or on the ceiling. The mould is not feeding on the tile, but on the biofilm that is on the surface.
Mould is microscopic and can only be seen with the aid of a microscope until a large mass has accumulated.
First, moisture is required in order for the mould to germinate. After germination, the mould hyphae secrete digestive enzymes that break down organic materials. Moisture is necessary for the enzymes to be effective. Removing moisture is the most effective method for stopping mould growth.
When the equilibrium relative humidity (ERH) of a surface is above 70% some mould spores begin to germinate. Depending on the species of mould, germination can take place within 4 – 12 hours. After germination, it takes time for the mould to develop, create spores and begin to colonise. Once again, depending on the species, colonisation can occur in 1 – 2 days.
A Serious Health Risk
When mould grows in a wet or damp indoor environment, there is a chance that it may develop substantially in volume to cause damage to the building materials and your health. Whether or not someone will have an adverse reaction to mould exposure depends on many factors that include but are not limited to:
– The amount of moulds present
– The type of moulds present
– How long the exposure may take place
– How sensitive the individual may be to the exposure.
As mould spores are carried in their air, inhaling these may cause health issues. If people are allergen sensitive, health problems may become very serious. Symptoms may include running or blocked nose, irritation to the eyes and skin, wheezing or more severely lung infections.
Asthma sufferers must be cautious inhaling mould spores can result in asthma attacks.
As moulds feed on their food source, they produce a by product of digestion that results in a musty odour, Microbial Volatile Organic Compound (MVOC). When this smell/odour is present, mould has begun growing.
Mould can grow on virtually any substance, as long as moisture (or water), oxygen and an organic source are present.
Moisture control is the key to mould control. When water leaks inside of your house, it is essential to act promptly. Any initial water infiltration should be stopped and cleaned. An efficient water removal and drying, as well as a thorough cleaning of the damaged materials, will prevent mould growth.
Remediation includes both the identification and correction of the conditions that permitted mould growth.
The remediation plan includes:
– A plan to permanently correct the water or moisture problem
– The use of appropriate personal protective equipment
– The steps to carefully remove mouldy building materials which will also prevent further contamination
The remediation plan may vary greatly depending on the size and complexity of the job. It also may require revision if circumstances change or new faces are discovered.
Selecting the right contractor to handle mould remediation who has the training and knowledge in their field of expertise is critical for a successful removal. Making sure the company you choose is an expert in this field and highly trained is a must.
A reputable contractor such as Juvenaire will ensure that the appropriate steps have been undertaken to remove mould and prevent it from coming back.
