During the winter months, damp and mould can be a problem for lots of us. Here is some information on this and how you can prevent it.


What is damp and mould?

Damp is caused by excess moisture in a home and can then lead onto mould and mildew appearing on your walls, windows frames, skirting boards, floors and furniture. This causes damage to the interior of a home.

It appears as lots of black dots, forming large clouds across the surfaces.


What types of damp and mould are there?

Condensation > this is probably the most common form of moisture in a home. This occurs when war, moist air comes into contact with cooler surfaces. Lack of adequate ventilation allied with modern occupancy lifestyles in terms of cooking, washing and bathing can lead to a build-up of excessive humidity and moisture within the property.

This is a problem because if left untreated, condensation can result in peeling decorations, unsightly mould growth and damage to fabrics and clothing, particularly in areas with little air circulation.

Penetrating damp > When moisture enters your home because of an external defect (for example a crack in a wall or missing roof tile).

Rising damp > Usually when a property’s Damp Proof Course (DPC) or membrane fails and moisture from the ground rises and damages plaster finishes and decoration.


How to reduce condensation in your home?

  • Control excess moisture by improving ventilation in your home, keep doors closed when cooking and bathing, don’t block air vents/trickle vents, try removing furniture from poorly ventilated external walls and wipe down surfaces when moisture forms.
  • Aim to produce less moisture by reducing sources of excess moisture (drying clothes indoors etc), ensure that tumble dryers are ventilated externally/in accordance with manufacturer’s recommendations and cover fish tanks: keep in mind house animals can produce moisture too!
  • Keep your home warm by increasing heating levels, using insulation and draught proofing (helps to keep your home warm and reduces fuel bills. 


How to prevent condensation-related mould (minor areas)?

  • Treat minor areas with an approved mould and mildew treatment.
  • Increase ventilation mechanically/naturally, particularly when cooking or bathing.
  • Reposition furniture where practical in affected areas.
  • Redecorate using a quality fungicidal paint to prevent mould spores from germinating once the mould has been treated. Strip any contaminated wallpaper – this is usually necessary.
