As most homeowners and business owners know, mould removal is no fun. Although mould grows outside and actually serves a purpose, mould inside the home only causes health concerns for you and your house. Essentially, the difference between whether mould grows in your home or not comes down to whether you have a moisture problem.
Humidity Causes Mould
If the weather’s been very humid for a few days in a row you might notice mould starting to grow in your home. When it rains for several days it’s especially common to see mould start to grow on walls, benches, and other surfaces because of the wet air.
If you live where humidity in the air is naturally high, like by the coast or another large body of water, then mould growth in your home can also be a recurring problem.
Also when moisture inside your house evaporates into the air it increases the humidity indoors. If your home isn’t well ventilated then the humidity will stay high for a long time.
Drying clothes indoors on clotheslines or stands is a common culprit when it comes to causes of indoor humidity problems. The household HVAC system can also create humidity troubles while it artificially heats or cools the air.
Sometimes people use humidifiers in their homes. But there are moulds that only need the humidity level to be higher than 55% to start growing. So if you need to use a humidifier in your home make sure to keep the humidity below 55%.
Not only does high humidity feed mould, but it means that puddles of water and damp materials in the home take longer to dry out. These wet surfaces can, in turn, create mould growth of their own.
Leaking Pipes Cause Mould
Water leaks from pipes are a common cause of mould growth. The worst leaks are the ones that go undetected because they are hidden out of view, like inside a wall. By the time you discover these leaks mould has usually started to grow already.
Leaks in Roof Cause Mould
Like some leaking pipes, a roof that leaks into the attic might not be discovered until it’s already lead to mould growth.
The best thing to do is to check the attic regularly for leaks and keep an eye on the ceiling below the attic. If you notice any signs of water damage on the ceiling or any mould that has grown through then you probably have a leaking roof.
Condensation Causes Mould
Cold surfaces can create condensation in your home. Condensation collects on cold metal pipes as well as on cold concrete floors, even if there is carpet over the top, and on walls. Places like these where condensation occurs are prime spots for mould growth.
Poor Ventilation Causes Mould
If your home is poorly ventilated it can create pockets of stagnant moist air that mould thrives in. Steam and water evaporating into the air create humidity inside which then needs to be circulated outdoors through windows to keep the moisture level balanced.
Poor ventilation also means wet surfaces dry out more slowly. Ventilation is especially important in rooms such as the bathroom and the kitchen where there is a lot of steam.
Wet Clothes Cause Mould
If you leave clothes wet for a long period of time in your house mould can grow on them as well as on other surfaces due to the moisture wet clothes release into your home.
Damp clothes left in a pile waiting to be washed for more than a day can lead to mould growth. Clothes left wet for over a day after being washed may also end up fostering mould.
Drying your clothes in a dryer instead of outside on the line releases a large amount of moisture into your home if the drier is not vented outside the house. Clothes drying inside on indoor clotheslines or racks will also create a build-up of moisture inside unless the room is well ventilated.

Flooding Causes Mould
It is almost inevitable that some mould problems will develop after your home has been affected by flooding. Obviously your house will be very wet for a long time during a flood, taking days or even weeks to dry out. Since mould only needs a suitable surface to be wet for 24 hours before it can grow this means there is a huge risk of mould growth.
Some dangerous toxic moulds require more extreme conditions than common moulds do, such as the toxic mould Stachybotrys chartarum which requires material to be very wet for several days to grow. A flood can create these conditions putting your home more at risk of being infected with dangerous toxic moulds.
Damp Basement Causes Mould
Basements often contain higher amounts of moisture or humidity than other rooms because they are usually not well ventilated. Basements are also often colder meaning more condensation occurs which leads to dampness and humidity.
Also, any water from leaks in your home will often end up running down to the basement since it is lower than all the other rooms. Not only is the mould more likely to grow in basements but because they are usually neglected mould growth may not be discovered until it is well set in.

Water at the House’s Foundation Causes Mould
Water building up in the yard and ground around the base of your house can cause frequent water problems for the foundation of your home.
If the ground around your home slopes towards the house rainwater will end up building up at the foundation. If this causes constant problems you might even need to do some landscaping to modify the slope of the ground so water drains away from the house. Alternatively, ditches and drains can be dug to channel water away from the home.
