Have a look at our blog to find out some of the main causes of mould in the UK, and why it often occurs.

What are some of the health risks associated with mould?

Mould can affect your health in many ways, from causing allergic reactions to respiratory issues. This happens through inhalation into your body or simply just by touching spores in the area.

This fungi growth causes risks to human health by generating toxic matter, irritants and allergens. People with pre-existing conditions such as asthma, or those with a weakened immune system, should be particularly careful around mould.

Condensation will form mainly in warm spots of the home, including bathrooms and kitchens. It is good to have a cleaning routine in place that includes wiping down surfaces and windows.

Mould frequently grows on window ledges, walls and corners of rooms. In winter, the chances of encountering it are much higher due to the cold weather conditions.

To stop mould from developing, it is recommended to dry clothes outdoors where possible, open the window when cooking, and have the heating on regularly.

During the remediation, our mould experts will be able to identify the source of the growth provide tips to avoid mould in the future.

Lack of ventilation

This is another leading cause as to why mould develops in properties around the UK. If you have a broken extractor fan, or don’t open the window while carrying out activities such as cooking or showering, then your chances of encountering mould growth increase.

Fresh air will be prevented from circulating around the room, and will react with moisture in the atmosphere to develop mould. Unfortunately for us, our homes provide the perfect environment for this fungi to grow.

Methods for preventing mould from lack of ventilation are very similar to those for condensation, including making sure that your extractor fan is in working order.

You should be particularly careful in the summer months, when humidity and heat are on the rise.

Leaking roof

A leaking roof can be stressful to deal with, whether it be from heavy rainfall or a hole in your structure. Contaminated water that comes into your house can be detrimental to your health – it is best to call in the professionals to see to this.

From this leakage, two kinds of mould can occur:

  • Systemic mould
  • Limited mould

If not dealt with, the mould and damage from the leaking can cause harm to your property. This includes threatening the infrastructure of the building to having a negative impact on your health and that of your loved ones.

Professional mould remediation experts will be able to get to the root cause of the issue, determine what kind of growth is causing the growth, and treat the problem. They can also provide advice on how to prevent the mould from coming back.


Additionally, mould can result following instances of flooding. It doesn't take long to develop either in the right surroundings, sometimes taking as little as 24-48 hours.

Flooding should be approached with caution. Similar to leakages, the amount of contaminants present in the water could be numerous, including sewage and dirt from outside environments.

Our experts not only provide effective mould removal services, but also flood damage cleaning. They will help restore your home to a safe environment, but you should not enter your home unless it has been declared safe to do so by the local authorities.

High humidity

Ideally, the humidity in your home should be between 30-50%. Anything above this and the property will become more susceptible to mould growth.

Like with condensation, opening windows will help to regulate the humidity within your home and allow air to circulate at regular intervals.

Increased humidity is more common in locations close in proximity to large expanses of water, but can be controlled with the right prevention methods.
