Mould is found in 1 in 4 UK residential properties and is classed as a category 1 health hazard. Black mould is the term which is assigned to a specific type of toxic mould known as ‘Stachybotrys chartarum’.
People far too often leave mould and think it is not a risk or can be easily wiped off. Mould should be thought of as being like a head of Broccoli. A wipe or household spray can take the top off or discolour it, but the roots will still be in wall and it will come back. Mould in residential properties is caused by lots of factors:
- The main cause is man-made issues. This includes lack of ventilation, condensation caused by cooking, showers etc, drying clothes on radiators, drying clothes on radiators
- Mould grows more prevalently in damp and cold conditions, so in the UK, November to May are extremely prevalent
- The warmer it is the more moisture that can be held, however, when moist air comes into contact with either colder air or a cold surface, it is unable to retain the same amount of moisture and the water is released to form condensation – you will often see this on a bathroom mirror if you don’t open a window while having a show
- The average family can produce up to 15 litres of water vapour in a day through normal activities
- Older properties often have more issues due to older insultation which tends to not retain heat as well
- Another key factor is that homes are now better insulated with double glazing etc which can lead to the though of a house being a contained box
