Having been subject to tightened legislation and ambitious government targets aiming to improve health and protect the environment, indoor air quality within domestic dwellings is a topic that is at the forefront of the minds of property developers and house buyers alike. While there are a host of elements that can impair the air quality inside a home, this article will focus on mould and excess moisture. In doing so, we will highlight the importance of tackling mould, offering up tips on how to prevent mould and reduce moisture in your projects.
For many homeowners, the primary motivation behind tackling mould is that it appears unsightly and unhygienic. The build-up of mould behind silicone seals can quickly spoil the look of a new and flawless bathroom. That being said, aesthetics are always of secondary importance in cases where there is a risk to the health and well-being of building occupants. According to the NHS, “Moulds produce allergens (substances that can cause an allergic reaction), irritants and, sometimes, toxic substances. Inhaling or touching mould spores may cause an allergic reaction, such as sneezing, a runny nose, red eyes and skin rash. Moulds can also cause asthma attacks.” What’s more, WebMD highlights that the effects of mould are not limited to allergy sufferers, explaining, “Whether or not you're allergic to moulds, mould exposure can irritate your eyes, skin, nose, throat, and lungs”, although the same article does list children, the elderly, the immune-compromised, and sufferers of chronic lung disease as being particularly at-risk.
Many of the solutions by which to combat mould formation are best planned and implemented during the building construction phase, and therefore it is essential that you as a house builder take measures to ensure that your projects provide a healthy living environment for future occupants and comply with legislation regarding ventilation and airflow in residential dwellings.
Mould is a type of fungus consisting of small organisms that are found almost everywhere. Mould can be black, white, orange, green, or purple. It thrives in moist and warm conditions and reproduces by releasing miniscule, lightweight spores that travel in the air and can be easily inhaled. In small quantities mould spores are generally harmless, but if allowed to grow the number of spores released is multiplied, resulting in health implications for home occupants. Moulds can grow on almost any home surface but are most commonly found on surfaces in damp rooms, such as bathrooms, kitchens, utility rooms, and basements.
Put simply, mould is caused by excess moisture. This may be as a result of leaking pipes, rising damp, or rain seeping in via damaged roofs or window frames. However, arguably one of the main causes of mould in domestic dwellings is condensation. This occurs when warm air comes into contact with cold surfaces in poorly ventilated rooms with a high level of humidity.
Measures to avoid mould can be divided into two categories: measures that can be taken by you, the house builder, during the design and construction phases, and those that can be performed on a regular basis by building occupants.
You should now be aware of the fact that mould is a significant problem that cannot be ignored. That said, you should also be better equipped to deal with mould and to advise your customers regarding practices to be adopted in order to prevent and eliminate mould.
