Mould and mildew often develops undetected in living areas and we are only aware of a musty smell or dark spots on the affected areas, usually walls.
Mould needs high humidity to survive and some types are capable of reproducing above a relative humidity level of 65%. Householders should therefore try to maintain a relative room humidity of 50% at an air temperature of about 19°C.
Mould tends to develop in areas of high humidity. This includes “permanently wet” areas such as corners of the bath, shower curtains and permanent-elastic joints. The problem can also affect walls that are inadequately insulated and where low surface temperature levels can lead to increased surface humidity and to condensation. This is often associated with inadequate heat insulation.
Once mould becomes visible, it’s important to determine the reason for its growth and not to simply clean the mouldy spots. This only offers a temporary cosmetic solution. Today it is a well-known medical fact that exposure to black mould can cause respiratory problems, such as asthma. This was long not recognized but is an issue which is taken seriously nowadays. Another common reaction to mould exposure is skin irritation and redness
Some tips to prevent mould
Wet materials need to be dried quickly.
If not, mould will grow within approximately 2 days. People are prone to leaving wet materials lying around in or outside the house. These things are the most common places where mold can develop.
- Cleaning, desinfecting and drying surfaces prevents mould growth.
Surfaces like sinks or floors should are also favorite places for mold; more so if they are wet most of the time. Mould can grow faster than you think it can. These wet surfaces pose many hazards for the residents living there.
- Reduce moisture levels in the bathroom by running an exhaust fan during and after showers.
If you have noticed how foggy the bathroom looks like after a shower, realize that those are moist places and a likely place for mould to develop. Exhaust fans can help minimize the moisture level in the bathroom as well as the possibility of growing mould
- Fix plumbing leaks and seepage to prevent the buildup of moisture and prevent the growth of mould.
Leaks are caused by pipes that have disintegrated already. It is important to replace old pipes as soon as they show signs of being dilapidated. No matter how much you try to keep the house clean, there are still areas that you are neglecting. There will always be a possibility of the growth of mould.
- Store clothing dry and clean to prevent the growth of mould on clothes.
It is best to keep used clothes dry. Better yet, wet clothes should be hung to dry. Try to put them outside or in places where there is air circulating.
- Increase the flow of air within your home.
Moving furniture away from walls and opening closet doors to permit air circulation limits the growth of moulds.Confined spaces and dark areas should be kept ventilated. Open windows are preferable over fans and air conditioning. There should be a stable availability of fresh air coming inside the house to prevent mould.
