Mould is a ubiquitous presence in our environment, both indoors and outdoors. It plays a critical role in the natural decomposition of organic matter, but its presence inside homes can lead to various issues. Mould spores are microscopic and travel through the air, making it easy for them to find their way into your home. When these spores land on surfaces with moisture, they begin to grow and multiply, forming colonies that we recognize as mould. Common types of indoor mould include Cladosporium, Penicillium, and Aspergillus, but the most notorious is Stachybotrys chartarum, often referred to as black mould.

The impact of mould extends beyond unpleasant odours and unsightly patches. Mould exposure can trigger a range of health problems, particularly for individuals with allergies, asthma, or compromised immune systems. Symptoms of mould exposure can include:

  • Respiratory issues such as coughing, wheezing, and shortness of breath.
  • Skin irritation and rashes.
  • Eye irritation, including redness, itching, and blurred vision.
  • Nasal congestion and sinus problems.
  • Headaches and fatigue.

In severe cases, prolonged exposure to certain types of mould, such as black mould, can lead to more serious health complications. It’s crucial to address mould issues promptly to protect your health and well-being. Furthermore, mould can cause significant damage to your property. It feeds on organic materials, gradually breaking them down. This can result in:

  • Damage to walls, ceilings, and floors.
  • Decay of wooden structures.
  • Destruction of fabrics, carpets, and upholstery.
  • Compromised structural integrity of your home.

Mould growth can also decrease the value of your property and lead to costly repairs if left unaddressed. Therefore, understanding the fundamentals of mould, its health implications, and its potential to damage property is the first step in effective mould management. By recognizing the signs of mould and taking proactive measures, you can maintain a healthy and safe living environment for yourself and your family.
