As the winter months approach in the UK, colder temperatures and increased rainfall can make properties more vulnerable to issues like damp and mould. These problems can affect not only the structure of your home but also the health and well-being of the occupants. To help you prepare for the winter season, we’ve outlined what causes damp and mould, how to spot them, and how to prevent damp and mould from affecting your property.

What Causes Damp and Mould?

Damp and mould are often the result of excess moisture in a building. This can occur for several reasons, including:

• Condensation: The most common cause of damp, especially during the colder months. When warm, moist air comes into contact with cold surfaces like windows or walls, condensation forms, leading to dampness and eventually mould.
• Penetrating Damp: This happens when water enters your property from the outside, often due to faulty roofs, walls, or windows.
• Rising Damp: Groundwater can seep up through your building’s foundations, particularly if your property lacks a proper damp-proof course.

How to Spot Damp and Mould

Before you can figure out how to prevent damp and mould in your home, it’s important to recognise the early signs of damp and mould to prevent serious damage. Look out for:

• Black or green mould patches on walls, ceilings, or around windows.
• Musty smells, which indicate the presence of moisture.
• Peeling wallpaper or paint.
• Cold or damp walls.
• Condensation on windows, especially in the mornings.

How to Prevent Damp and Mould

Preventing damp and mould is all about managing moisture and ensuring your property is well-maintained and ventilated. As a result, it in essential that you keep on top of your property year-round.

Here are some of the best ways to get your home ready for winter and avoid these common problems:

1. Ventilate Your Home

Good ventilation is key to reducing condensation. Make sure to:

• Open windows daily to allow fresh air to circulate, even during colder months
• Use extractor fans in kitchens and bathrooms during and after cooking or showering
• Avoid drying clothes indoors, or ventilate the room well if you do
• Keep furniture slightly away from external walls to allow airflow and reduce condensation

2. Use a Dehumidifier

A dehumidifier can help reduce excess moisture in the air, particularly in rooms that tend to trap humidity, such as basements or bedrooms. This is particularly useful in colder months when opening windows is less feasible.

3. Keep Your Home Warm

Maintaining a consistent temperature throughout your property can help prevent condensation from forming. To keep a regular temperature in your house, you should consider:

• Setting your heating to a steady, moderate level throughout the day to keep your home warm.
• Insulating your home by sealing any draughts around doors and windows and considering double glazing if you don’t have it already.

4. Fix Leaks and Maintain Your Property

Penetrating damp is often caused by external factors like leaky roofs or faulty gutters. This can be prevented by regular property maintenance, such as:

• Check your roof for leaks and ensure there are no broken or missing tiles.
• Clear gutters and downpipes of any debris to prevent blockages that could lead to water seeping into the walls.
• Inspect your windows and doors for gaps or cracks, and seal them up as necessary.

5. Dry Clothes Outside or Use a Tumble Dryer

Drying clothes indoors can significantly increase humidity levels, leading to condensation and damp. If you can, try one of the following alternatives:

• Dry clothes outside or use a tumble dryer that vents moisture outside.
• If drying indoors is necessary, do so in a well-ventilated room and leave windows open.

6. Treat Existing Damp and Mould

If you already have damp or mould in your property, it’s important to deal with it promptly to prevent it from worsening:

• Clean mould off surfaces with a mould removal spray or a homemade solution of water and vinegar. Wear gloves and a mask to avoid inhaling spores.
• Address the cause of the damp, whether it’s poor ventilation, a leak, or rising damp, and take the appropriate steps to fix it.

Preparing Your Property for Winter

Winter brings harsher weather conditions that can exacerbate damp and mould issues. By taking the necessary steps now, you can protect your property from damage and ensure a healthy living environment.

Follow this 3-step guide on how to prevent damp and mould in your property:

• Inspect your property for signs of potential water ingress, such as cracks in walls or broken roof tiles.
• Service your heating system to ensure it’s ready for the colder months, helping to keep your home warm and dry.
• Ensure your insulation is adequate to help maintain a consistent temperature and prevent condensation.
