Black Mould Around the Home

The most significant contributor to black mould is excess moisture caused by everyday living and poor ventilation. As we continue to install heat retaining insulation and new types of double and triple glazing that may not have trickle vents, we remove the natural ventilation required to allow our homes to ‘breathe’.

Black mould can occur anywhere around the home but the extent of the problem can vary depending on the amount of moisture and tempetature.

If you are concerned about black mould on your walls, ceiling, around your windows or in the bathroom or kitchen, here is our handy guide on what you need to know and how to treat against about black mould.

Why do I have Black Mould in my Home?

If you spot black mould in your home, the first step is not to worry. Black mould is a common property problem that can be caused by;

1. Excess moisture through condensation

Everyday activities from bathing, drying clothes, washing even breathing contribute to the natural humidity, creating a build up of water vapour.

If water vapour is not able to escape, it will land on cool surfaces i.e. walls or windows which can cause walls and windows to feel wet to the touch. On windows, you will be able to physically see the dew (water droplets and vapour) but on walls, they will feel damp to the touch. It is this moist environment that black mould needs to germinate.

2. High levels of humidity and poor ventilation

With excess moisture in the atmosphere, water vapour needs somewhere to escape or seeks cool surfaces to land on. Partly down to the typical British weather, we don’t open our windows or ventilate our homes enough to allow the damp air to escape. Modern double glazing and insulation technology acts as a barrier and prevents humidity from escaping.

3. Other damp related issues

Black mould can be a strong indicator of other underlying damp problems such as penetrating damp, allowing black mould to germinate and grow on the surface of the wall. If other damp related issues are the cause, the sign of mould will be combined with other signs of damp such as localised damp patches, peeling paint or wallpaper.

What is causing Black Mould to Grow?

Black Mould On Walls

Black mould on walls is a common problem that occurs in properties due to excess moisture from condensation, poor ventilation, flood damage, water ingress or a combination of problems. It is essential to assess and identify the root of the problem before repairs begin.

Black Mould Behind Furniture

You may be surprised one day to discover black mould growing on the wall, behind a chest drawers or bedroom cupboard. It is very common to find mould growth behind furniture in rooms with poor ventilation. Improve the ventilation by ensuring furniture is not push up against the wall and keeping the room at a constant temperature.

Black Mould on the Ceiling

Mould can easily develop on any surface with the right moisture content and exposure to black mould spores. On ceilings, mould can develop from underlying damp issue such as penetrating damp if the mould is localised to one area or where a panel of insulation is missing. Identify the source of the moisture from the roof/floor above is the first step towards treatment.

Black Mould around Windows

Black mould around windows can be a sign of an underlying cold bridging issue, especially if you notice the tell-tale sign of water vapour on the window. Improving the ventilation in the property and reducing the excess moisture in your property will improve the situation.

Black Mould in the Kitchen and Bathroom

Daily activities, such as washing and cooking, can cause condensation to build when there is insufficient ventilation allowing black mould to grow. Improving the ventilation and reducing the excess moisture in the air, you should begin to see an improvement.
