Mould Explained

Mould is a tiny microscopic organism that multiplies by releasing spores as it feeds on a combination of oxygen, moisture and the organic material it forms upon. Mould germinates in properties suffering from an excessive build up of moisture in the air.

Signs Of Mould Problems

Common places to find mould problems are walls, window sills, kitchen cupboards, curtains, clothes, shoes and behind furniture. Mould causes a musty damp smell, although occupants can become nose blind over time. While mould is growing it will appear shiny and slimy before changing to a black or dark green colour. When mould has dried out and died it will turn grey and powdery looking.

Window sills

Mould spores will gather on window frames. If condensation settles for a period of more than 6 hours mould spores start to breed. If you have a mould problem, you will find traces of mould in the silicon sealant.

What Causes Mould Growth?

There are two main reasons why mould starts to grow in a property:

Excessive moisture

Mould requires moisture over a period of time to germinate. The source of moisture is usually condensation caused by everyday living such as, breathing, cooking, showering, and drying clothes indoors. On rare occasions the excess water can come from a plumbing defect, leaking roof or a washing machine.

Poor ventilation

A property with poor air ventilation will always attract mould spores. If moisture is not allowed to escape the property will suffer from constant high humidity levels resulting in mould growth.

Why Is Mould A Problem?

Mould is unsightly to look at. Mould can affect your health, especially children and elderly people. Mould will attack your personal possessions such as clothes and shoes. It can also be an indicator to other problems such as condensation or property defects. Mould can aggravate existing health symptoms.

Mould And Dust Mites

Dust mites live in bedding, carpet, clothes and soft furnishings.  Dust mites thrive in humid moist mouldy conditions, the most common environment for the formation of mould. Many people are allergic to dust mite droppings.  The mite itself is normally allergy free.  Its droppings contain proteins which are the cause of the allergy

Mould And Health Problems

Inhaling or touching mould spores may cause an allergic reaction, such as sneezing, a runny nose, red eyes and skin rash. Mould spores are everywhere, mould spores are airborne  and are being constantly circulated throughout the indoor air. This is a serious problem for asthma sufferers.

Mould Removal Products

There are many mould removal products on the market. Unfortunately they do not target the route cause of the mould problem. Mould removal products i.e mould paint, mould bleach, antimicrobial products only temporarily clean the area. Even if surfaces look clean, the roots of the mould are airborne and remain, micro mould spores are not visible to the naked eye.

Using ineffective mould removers doesn’t just waste time and money, it allows a relatively minor mould problem to grow into a very serious problem. Reducing humidity levels and good ventilation is the only effective way to totally eradicate a mould infestation problem.
