how to stop rising damp in your home

Rising damp is a common issue in many homes, particularly in older buildings. It occurs when moisture from the ground travels up through the walls, causing damage to the structure and creating cracks, damp patches and a musty environment.

It can cause a lot of problems to your property, not to mention your health. But fortunately, there are effective ways to combat rising damp.

Here's a comprehensive guide on how to stop rising damp in your home.

Identify the rising damp

Identifying rising damp in your home is important for proper treatment. Here are the key signs to look for:

  • Visible mould: Mould on lower parts of your walls suggests excessive moisture.
  • Tide marks on walls: Look for watermarks that appear up to a metre above the floor on your walls.
  • Peeling wallpaper: If your wallpaper is coming off or looks bubbly, it might be due to dampness.
  • Damp patches: Noticeable wet spots on your walls, especially after rain, are a sign of rising damp.
  • Musty smell: A persistent damp, mouldy smell in your home often indicates rising damp.
  • Rotting wood: Check skirting boards and floorboards for decay or fungal growth.
  • Crumbling plaster: If the wall plaster is flaking off or has white, salty deposits, it might be damp.

If you notice any of these symptoms, it's time to take action. So, how do you stop rising damp?

How to stop rising damp

Improving drainage and ventilation

One of the first steps in combating rising damp is to improve the drainage and ventilation around your property. Ensure that your gutters and downspouts are clear and functioning properly. Good ventilation, especially in basements and crawl spaces, is also very important as it helps to reduce the amount of moisture in the air.

Repairs and waterproofing

Fixing cracks or openings in your home's foundation is essential to stop moisture from getting in, which helps prevent rising damp. It's important to seal these gaps quickly, as they are common ways for moisture to enter your home.

Additionally, putting a waterproof layer on your exterior walls adds more protection against dampness. This combination of sealing the foundation and waterproofing the walls is a key step in keeping your home dry and safe.

Installing a damp-proof course

A damp-proof course (DPC) is a protective barrier in the walls of a building, often made from materials like slate, plastic or bitumen, designed to stop dampness from rising up through the walls.

If you live in an older home that doesn't have a DPC (damp-proof course) or it's damaged, consider installing a new one or fixing it. It is really effective in helping protect your home from rising damp and related issues.
