Mould in the House: Causes, Consequences and Solutions

Mould in the house is more common than you think, and it can significantly affect our lives. Not only do the black or green patches on walls look unhygienic, but mould in the house can also be harmful to our health. How does it actually arise, what are the risks and, most importantly, what can you do to prevent mould in the house? This article provides an overview of everything you need to know about mould in the house.

What Is Mould?

Mould consists of tiny organisms that grow from spores. These spores are always floating in the air and are harmless on their own, but when they find a damp, warm spot, they can settle and multiply. This leads to the mould patches we see on walls, ceilings or sometimes even on furniture. Mould thrives particularly well in dark and damp environments – think of bathrooms, basements or kitchens.

Mould often occurs in the house when there is poor insulation or in older buildings, where it can be more difficult to maintain a stable humidity level. Source: Milieu Centraal

The Dangers of Mould

Mould in the house can not only be unsightly; it also carries health risks. The spores released by mould can cause respiratory problems and lead to symptoms such as coughing, sneezing and breathing difficulties. People with asthma, allergies or a weakened immune system are particularly at risk. For them, mould can even cause serious respiratory problems. With prolonged exposure, even people without existing health issues can develop complaints. Source: Longfonds Mould in the house is not only harmful to health, but also to the home itself. Mould patches can damage plasterboard and wooden surfaces, leading to permanent damage. Removing this damage can be costly, especially when it involves structural parts of a building, such as load-bearing walls or ceilings. Maintenance costs can therefore quickly add up if mould in the house is not tackled early. Source: Gezondheidsraad

How to Recognise Mould?

Mould in the house is usually recognised by dark spots on the wall, ceiling or in the corner of a room. It is often black, green or brown in colour, and sometimes you can feel or smell it. Mould often has a musty, earthy smell. It is important to be vigilant, especially in rooms that are damp. Sometimes mould is hidden behind furniture or in cracks in the wall, making it harder to notice. Regular checks and quick action are therefore essential to prevent the mould from spreading.

Fighting Mould in the House

Removing mould in the house sometimes requires special products. Small mould spots can often best be tackled yourself with cleaning vinegar or a special mould remover. Spray the surface, let it soak in and scrub the mould away with a brush. Always make sure to wear gloves and a face mask to protect yourself from the spores. For larger mould problems, it is often wise to call in a professional. These people have the right equipment and expertise to thoroughly remove mould, especially if it has become deeply embedded in walls or ceilings. After removing the mould, it is important to take measures to prevent new mould in the house. Regular ventilation, good insulation and immediately repairing leaks are essential to combat moisture problems. By acting preventively, you can ensure that mould has less chance to develop again.

Preventing Mould: Tips and Tricks

Preventing mould is often easier than removing it. Here are some tips to prevent mould in the house:

• Ventilate daily: Ensure moist air can escape by opening windows, especially after showering or cooking.
• Heat your home evenly: Try to minimise temperature differences, as cold walls attract moisture more quickly.
• Use a moisture meter: This allows you to monitor the humidity in your home and prevent it from getting too high. Ideally, the humidity should be between 40% and 60%.
• Check for leaks: Regular maintenance and quick repair of small leaks can prevent mould problems.

Ventilation is crucial for a healthy indoor climate. When moist air cannot escape, it is trapped in the home, which stimulates mould growth. Source: Rijkswaterstaat

Conclusion

Mould in the house can pose a serious threat to both the health of the residents and the home itself. By being vigilant and taking preventive measures, you can significantly reduce the chance of mould. If you do experience mould, it is important to act quickly and remove the mould as soon as possible. Remember that mould can only grow if it gets the chance – keep your home dry and well-ventilated, and the chance of mould will decrease.
