Mould: How it Occurs and What You Can Do To Prevent It


A common complaint among both homeowners and tenants alike is the unsightly (and potentially dangerous) growth of mould.   Common no matter the season, it’s to be expected in a country with as much annual rainfall as Britain, but armed with a little knowledge and a few simple techniques you can ensure your property or rental property is mould-free.

Mould: How it occurs

Mould spores are released as a result of mould growth and, though invisible, they are always in the air, acting at best as an annoying allergen, at worst as a potentially large mould growth problem in your home.    The mould spores require a moist, warm environment in which to grow and thrive, so it’s no surprise the most common place you find mould is in the bathroom.  The steam from a hot shower, the arrant puddles of water left on the floor, are all conducive to mould growth.

Unfortunately, mould can also be a sign of an issue bigger than simple condensation, such as a leaking or burst pipe, rain water seeping in from the roof, rising damp caused by ineffective damp-course, etc.  If you suspect one of these issues to be the culprit, it may be best to call in a plumber to make sure the matter is resolved at the source.

How to Prevent Mould Growth

Moisture is simply an unavoidable by-product of living:  steam from the shower, heat from cooking, washing clothes, and even just simply breathing all generate condensation which, in turn, can be conducive to mould growth.  The key to minimising the effects of condensation lies in properly ventilating your home.  Extractor fans in the bathroom and kitchen can often go a long way towards removing excess moisture from the air, as can opening a window after a bath or shower to allow the room to ventilate properly.  Though it can seem like an undesirable option, especially in the winter months, leaving a window open for just a little while in order to stabilise the fluctuation from cold to hot can do wonders for preventing the further spread of mould.

How to Treat Existing Mould

Mould is fairly easy to treat with any bleach-based or fungicidal product.  For the bathroom tiles, walls, and sealant around the tub and sink, bleach is a good option for getting rid of the growth.  There are also many fungicidal products on the market which are completely safe to use providing the manufacturer’s instructions are followed, and these can be used to wipe down walls or shampoo carpets.  Distilled Vinegar and Baking Soda are both good alternatives if you are not keen on chemical based cleaners. Vinegar is a mild acid which can kill a high percentage of mould species and Baking Soda is a mild abrasive which can kill mould spores and absorb moisture to help keep mould away.

Lettings and Mould

Mould is no easy problem for either tenants or landlords in the Seaford lettings market and often has more to do with how property is lived in rather than the property itself.  Both parties can take cautionary steps to prevent mould growth from becoming a problem, such as the installation of extractor fans by the landlord, and steps to ensure reduced condensation on the part of the tenant. Its recommended to keep an open, positive dialogue between tenant and landlord, and working together to tackle the issue from both sides, rather than pointing fingers.

    • Molds are found everywhere inside and outside, and can grow on almost any substance when moisture is present. Molds reproduce by spores, which can be carried by air currents. When these spores land on a moist surface that is suitable for life, they begin to grow. Mold is normally found indoors at levels that do not affect most healthy individuals.

    • Mold seeks MOISTURE, WARMTH, and FOOD, and
      all three conditions are necessary for it to grow. Mold is most likely to
      find a place to grow in a bathroom, basement or kitchen, but it can grow in
      other rooms if conditions are favorable. The climate where you live and the
      living habits in your household can affect the ability of mold to grow.

    • Black mould removal is a relatively easy task that should only take around 30 minutes to complete if you have the right materials. Black mould removal kits can be purchased from the Wise Condensation Shop that will give you everything that you need to remove black mould. However, black mould removal is only an interim solution and unless you solve the damp or condensation issue causing the black mould, it will eventually return.

    • Mold spores can thrive and reproduce in wet or damp parts of your home: areas that have had flooding or where leakage has occurred in roofs, pipes, or walls, or areas around house plants, especially ones that sometimes are over-watered. In just 48 hours, a moist environment combined with room-temperature conditions and an organic food source can lead to mold growth.
