During the winter months, many properties suffer from damp and mould growth due to condensation. Ugly black patches and a musty smell are usually the first signs. Whilst there are things that landlords can do to help with the causes, like provide central heating systems and effective guttering, tenants have a responsibility in this area too, so please read on.
Causes and signs of condensation
Air can hold moisture - the warmer the air, the more moisture it can hold. If moist air is cooled by contact with cold surfaces, such as walls, windows or mirrors, the moisture condenses into water droplets (known as condensation). Mould often occurs because of this condensation and is normally only a problem during cold weather. It appears as pinpoint black spots, usually on the side surfaces of external walls, in corners and in poorly ventilated spaces.
Where does mould occur?Everyday things like cooking, washing, bathing and even breathing create moisture which is released into the air.
Because of the high moisture levels in bathrooms and kitchens these are probably the most common areas affected. North-facing rooms, places with poor ventilation, like cellars, or basements and the rear/sides of cupboards or wardrobes can suffer too.
It’s not just a problem confined to older properties either. According to the National House-building Council, the materials used to build a house take a long time to dry out properly and as a result, brand new homes can also be affected.
How to reduce/prevent condensation
How to get rid of mould
The areas around showers and baths need particular care to avoid a mouldy takeover. Methods of mould removal will vary depending on the location of the stain.
To eradicate mould on tile grout, use a toothbrush dipped in bleach, or for a natural remedy, try diluted vinegar. A paste made from water and baking soda also works well. Leave to soak for 15 minutes then scrub like mad. Don’t forget to rinse well afterwards. For a shop-bought solution, try Dettol Mould & Mildew Remover which is designed to remove even ingrained mildew.
Stained sealant around the shower or bath can be tricky to get rid of. If bleach doesn’t shift it, the only solution might be to cut it out with a Stanley knife and apply new sealant.
Mould on shower curtainsTreat mildew stains on shower curtains with a weak solution of bleach and water mixed up in a plastic bottle. Spray it on, then wipe off. Or after a bath, add soda crystals to the water and try soaking the curtain overnight for a more eco-friendly option without the pungent fumes! If you don’t have soda crystals, use biological washing powder. Scrub any pesky bits of mould stuck in the hem or seams with a nail brush.
Mould on walls and ceilingsTackle mould on walls, window frames and ceilings with Polycell 3in1 Mould Killer. Spray the affected area well, then wipe away the mould with a cloth or sponge. Its powerful fungicide kills existing mould and discourages regrowth. The treated area can be repainted or papered once dry.
