Damp Proofing Question

Green mould

I have a built in wardrobe in my bedroom against an outside wall. I have no lining in my wardrobe and recently I've noticed green mould on a lot of my clothes and shoes and the wall feels wet at times. Can anyone advise me the best thing here?

Hi there
you are suffering from condensation in this instance where its a wardrobe I would use a thermal board on the exterior walls dot and dab method to make them warmer and ventilate the room better ,also keep your bathroom and kitchen doors closed when in use and leave a window slightly open if there is no extractors fans.

Condensation accounts for approximately 70% of reported domestic damp.

Condensation can commonly be attributed to a lack of balance between heating and ventilation resulting in a rise in relative humidity. Air can hold more water vapour when warm than when cold. When warm air is cooled, such as when the heating system is switched off at night, it will deposit the water that it can no longer retain as condensation on a cold surface.

A similar effect that can be demonstrated by breathing onto a mirror or other cool surfaces. In its less serious form, condensation may “steam up” windows and mirrors.

In more severe cases, it can be absorbed by surface wall finishes and underlying plaster causing dampness although the underlying brickwork or masonry will normally be of a lower moisture content. It may cause mildew on fabrics and leather and, in extreme cases, can cause walls to be visibly wet. It is frequently accompanied by mould growth, of which the most common is “black spot” – a mould which appears first as small soot-like spots, and which can join up and cause large black areas. Condensation may occur at any height on almost any cool surface.

Condensation damp permits fungal growth. Materials such as wood, paper, wallboard, ceiling tiles, furnishing fabrics and even masonry and plaster can provide nutrients sufficient for mould growth providing the controlling factor is present i.e. the availability of sufficient moisture.
