Key Takeaways:

  • Mould Prevention Challenges in Winter Months: Damp, mould, and mildew intensify during colder months, posing health risks and affecting furniture and building structures. The airborne spores that cause mould flourish in damp and warm conditions.
  • Condensation and Mould Formation: Condensation, a key contributor to damp, occurs when warm, saturated air encounters colder surfaces inside the house. Winter activities like boiling kettles, hot baths, and limited ventilation create conditions ideal for condensation.
  • Initial Steps for Mould Prevention: Effective mould prevention starts with identifying affected areas in the property, including basements, window panes, and ceilings. The winter season, characterized by reduced ventilation, exacerbates the build-up of humid air, creating an environment conducive to mould infestations.

Ventilation is a key component to prevent mould on walls in your home. The routine activities you do in your home give rise to damp and mould problems.

as mould inhibitors for paints and mould-resistant drywall or sheetrock. The standard drywall contains gypsum plaster in between the paper layers, whereas the mould-resistant one is paperless, making it waterproof. You can use the moisture-resistant drywall in your laundry rooms, kitchen, and bathroom.

Keep indoor humidity levels in check

Use a moisture meter to measure the humidity levels in the house. The ideal reading is between 30 and 60 per cent as per EPA. Moreover, you can select the exact humidity level, especially the areas you feel are affected by the moisture meter.

If you see any signs of moisture or condensation on pipes, windows or walls, it will lead to mould and damp later on. So, dry such areas and get rid of the source of damp immediately.

Don’t let water accumulate around your building

Look for standing water or chronic damp that may be the reason behind the increasing indoor humidity and ideal conditions for mould to grow. If you don’t have a slope around your property, water may accumulate and enter the building. Moreover, check for damp around hot water tanks, freezers, sump pumps, basements, windows and doors, or see if you have any puddles. Apart from it, inspect crawl spaces for foundation leaks or groundwater damp.

Repair them timely. Besides, always keep an eye on any kind of water stains after the rain. Always wear rubber gloves to clean gutters. If you see any damage, repair it as quickly as possible to prevent mould from appearing on the walls.

Improve airflow in your house to prevent mould on walls

The air is unable to hold more moisture when its temperature decreases, according to EPA. The excess moisture in the air starts appearing on floors, windows and walls without good airflow in your building.

Therefore, increase the air circulation by opening windows, and doors, moving timber or other furniture away from walls, and opening the doors of cupboards that are in colder damp rooms. Fresh air reduces moisture and keeps mould away from your premises.

Check household plants for mould

Besides offering aesthetic beauty to the house, household plants give fresh air. However, they bring mould as well. The soil in plants is damp, and it makes ideal conditions for the mould to thrive and spread all over the house.

One of the quickest and most effective ways to deal with the issue is to add Taheebo tea to the water that you use for plants. It prevents the growth of mould in the soil. You can find this tea easily at your nearby local stores to remove mould from your plants.
