Damp and mould

Protect your home and health

Understanding the problem

Damp, mould, and condensation are common issues in UK homes. While they might seem similar, they have different causes and require different solutions.

Condensation

This is the most common type of damp. It occurs when warm, moist air cools on cold surfaces, such as windows or walls. Everyday activities like cooking, showering, and even breathing contribute to this moisture.

Over time, condensation can lead to mould growth, particularly in poorly ventilated areas.

Damp

Damp can occur due to various factors:

• penetrating damp - water seeps through cracks in walls or roofs
• traumatic damp - water damage from leaks or floods
• rising damp - moisture rises from the ground through walls and floors

Damp can cause significant damage to your home and pose health risks.

Mould

Mould thrives in damp conditions. It can grow on walls, ceilings, and other surfaces. Mould can cause respiratory problems, allergies, and other health issues.

By understanding these issues and taking preventative measures, you can protect your home and your health.

Health risks of damp and mould

Damp and mould can significantly impact your health, particularly your respiratory system. Common symptoms include:

• coughing
• wheezing
• shortness of breath

In severe cases, exposure can lead to:

• fungal infections such as aspergillosis
• exacerbation of existing conditions like asthma and COPD
• eye irritation
• skin conditions including eczema
• mental health issues like increased anxiety and stress due to living in poor conditions

People most at risk

Certain groups are more vulnerable to the health risks of damp and mould:

• people with pre-existing health conditions
• children
• elderly individuals
• pregnant women
• people with weakened immune systems

Identifying different types of damp

Understanding the type of damp in your home is crucial for effective treatment. Here's a breakdown of common types:

• condensation damp
  • cause: excessive moisture in the air, often due to poor ventilation or inadequate heating.
  • signs: water droplets on windows, mould growth, damp patches on walls.
• penetrating damp
  • cause: water entering the building through cracks or defects in the structure.
  • signs: damp patches on walls, particularly after rainfall, discoloured paint, and salt stains.
• rising damp
  • cause: water rising from the ground into walls due to a faulty damp-proof course.
  • signs: damp patches at the base of walls, peeling wallpaper, and salt stains.
• traumatic damp
  • cause: water damage from leaks or floods.
  • signs: isolated damp patches, often with a musty smell, and visible water damage.
