Dealing with Damp & Condensation in your Home

During the colder months, damp and condensation can become a problem in many homes. Left untreated, they can lead to health issues, damage to furniture and belongings, and the development of black mould. Below, we outline the causes, effects, and solutions to help you manage and prevent these issues effectively.

What Causes Condensation?

Condensation occurs when warm, moist air comes into contact with cold surfaces, such as windows or external walls. This creates water droplets, which can lead to mould growth if not addressed. Everyday activities like cooking, showering, and drying clothes indoors contribute to moisture in the air.

 

Did You Know?

  • A family of four can add up to 40 litres of moisture to the air weekly just by breathing.
  • Activities like bathing and cooking add an additional 15-20 litres of moisture per week.

How to Spot Damp Issues

 

Rising Damp: Often seen as a tide mark on walls caused by failed damp-proofing

 

 

 

Penetrating Damp: Caused by water entering from outside, leading to blotchy patches, crumbling plaster, and puddles.

 

 

 

Condensation: Common in areas like windows, bathrooms, and kitchens, resulting in black mould and damp smells.

 

If you suspect damp in your property, seek advice to address the cause and find a suitable solution.

Tips to Reduce Condensation and Damp

Ventilation:

  • Open windows or trickle vents for 10 minutes daily to allow airflow.
  • Use extractor fans in kitchens and bathrooms.

Heating:

  • Maintain room temperatures above 17°C to reduce condensation on walls and windows.

Insulation:

  • Insulate walls and ceilings to warm surfaces and reduce moisture build-up.

Moisture Control:

  • Avoid drying clothes on radiators; use a drying rack near an open window.
  • Cover pans when cooking and avoid overfilling kettles.
  • Regularly wipe windows and walls to remove condensation.

Room-Specific Tips

Living Room:

  • Lay thick carpets and use heavy curtains for warmth.
  • Ensure furniture is not blocking ventilation.

Kitchen:

  • Use lids on pots when cooking.
  • Keep doors closed to contain steam.

Bathroom:

  • Take shorter, cooler showers.
  • Open windows or use extractor fans during and after use.

Decorating:

  • Use mould-resistant paint and fungicidal wallpaper paste in areas prone to damp.

What to Do if You Find Mould

Clean affected areas with a fungicidal wash, following manufacturer instructions. Special paints can delay mould reappearance, but it’s vital to address the root cause of condensation.
