How To Prevent Mould Around Your Windows This Winter

With the winter months fast approaching, it is essential to be proactive in keeping your home dry and mould-free. Mould can grow anywhere with high humidity and little air circulation, including around windows. This blog post will provide you with a few tips on preventing mould from growing near your windows this winter.

Ventilation and Light Preventing Mould

Ensure that the area around your windows is well ventilated. This means having fans near open spaces and opening your windows on warmer days to let in some fresh air. 

Keeping window blinds closed may also help prevent mould from growing by blocking out sunlight, encouraging mould growth. 

Staying on Top of Mould Growth by Cleaning 

Clean surfaces regularly with an antibacterial spray or solution, particularly if they feel wet or humid when touched. As mentioned earlier, moisture encourages mould spores, so regular cleaning will reduce these spores and reduce the risk of mould. 

Be mindful of what is stored around windows; avoid stacking things up near windows or against walls that may obstruct airflow, as this can encourage dampness and increase humidity levels too much (i.e., by running a clothes dryer next to an open window during winter months). If possible, keep any surfaces around windows clear of clutter to allow for maximum airflow.

Keep Condensation Low to Prevent Mould

Suppose you do not have a fan or are unable to keep your windows open for whatever reason. In that case, it’s essential to be mindful of any condensation forming around your windows during colder months, as this will increase the likelihood of mould developing due to high humidity levels. 

Ensure you are regularly airing your house. Windows accumulate moisture which can lead to mould if not appropriately ventilated, so they must dry out thoroughly after washing or rain before closing them for the night (overnight dew accumulation may also contribute to window condensation). 

Finally, when airing laundry during the winter season, never leave wet clothes hanging on a line near open windows. This may encourage condensation formation, leading to mould growth if left unattended for too long.

Extractor Fans Can Help Prevent Mould

Consider investing in an extractor fan if you cannot keep your windows open or have issues with condensation forming. Extractor fans can help ventilate moist air from areas most likely to accumulate it, such as near bathroom and kitchen windows. This will reduce humidity levels in these spaces, which reduces the chance of mould growth due to the build-up of moisture in warmer weather conditions. 

If you do not have an extractor fan installed at home right now, consider adding one during the winter months. This period tends to be when kitchens and bathrooms are used more frequently than other rooms, so they require increased ventilation compared to other times of the year.

Window Frame Upkeep

Ensure that window frames are in good condition, with any crevices or gaps filled in to prevent leaks and moisture from getting inside. If there is already mould around your windows, clean it off as soon as possible using an antibacterial solution so you limit its spread. 

Mould can damage windows and be an ugly eyesore and health hazard (especially for those with existing breathing problems like asthma). Prevention is better than cure in this case, and keeping an eye on your windows during the winter months when mould is likely to form is the best way to stop it in its tracks.
