Nine ways to reduce mould growth in your apartment

While some homes have been deemed unliveable due to the extent of mould growth being present in apartments, it can be found in most buildings – whether it’s growing under the kitchen sink, on your bathroom tiles, in shaded and wet areas of the building, or in the cupboards.

Mould usually grows in damp areas, such as the basements, kitchens, and bathrooms. Unless you have a major water defect that is causing the mould, minor mould issues can usually be prevented by keeping your home dry and ventilated.

Here’s our PICA Group top tips to reduce mould growth:

1. Open the windows

Ensure windows are open for ventilation in your apartment, even in cold weather, your windows should still be open even if it’s just by a fraction.

2. Replacing your plants

Mould often grows in the soil of household plants. If you’d like to reduce the amount of mould in your home you could replace your real plants with false plants and flowers.


3. Use of dehumidifiers

If you don’t have air conditioning, you could use a dehumidifier instead. They can be purchased from appliance stores or online.

4. Using air-conditioning

Air-conditioning can be costly to install but relatively cheap to run. As well as regulating temperature, it can help in reducing mould growth by keeping the home dry through a dehumidifier function.


5. Dry laundry outside when possible

Hanging wet clothes inside can increase the moisture in the room by nearly 30% which in turn encourages mould growth in your apartment. When possible it’s better to dry wet washing outside, in a tumble dryer, or in a well-ventilated indoor space away from bedrooms and living areas.

Moisture absorbers are crystals are exposed to air, they absorb excess moisture and gradually dissolve into a saltwater solution. They are great to soak up excess moisture in cupboards and wardrobes and can keep your clothes protected.

7. Using fans

Keep the fan running for at least 5-10 minutes after you have finished your bath or shower. Enquire about the possibility to duct or vent appliances that cause moisture such as your kitchen exhaust.

8. Monitor humidity indoors

Indoor humidity should be kept between 30 and 60 percent. You can measure humidity with a moisture meter purchased from your local hardware store.

9. Dry wet areas immediately

Mould can’t grow without moisture, so tackle wet areas right away. Hang up bath mats to dry, fix leaky taps, don’t leave washing in the machine or water in buckets. Use a squeegee to clean away excess water after every bath or shower. Also, use an eco-friendly after-shower tile spray at least every second day. When scouring your bathroom, don’t just surface clean tiles, but take the time to scrub the grout in between as well.
