What is Mould?
Mould is a type of fungus that grows in damp, warm environments. It reproduces through spores that can spread through the air and settle on surfaces. When these spores land on a surface that is damp or wet, they can grow into visible mould colonies.
Why Mould Grows on Sealant
Window sealant, typically made from materials like silicone or latex, is prone to mould growth because it can trap moisture, especially if it’s not properly applied or if the sealant has started to degrade. If your windows are not adequately sealed or if there’s persistent condensation, mould is likely to develop.
Identifying Mould on Window Sealant
Visual Signs of Mould
Mould can appear as black, green, or white patches on your sealant. It may also have a fuzzy or slimy texture. If you notice any discoloration or texture changes on your window sealant, it’s likely mould.
Health Symptoms Linked to Mould Exposure
Exposure to mould can lead to health problems like respiratory issues, allergies, and asthma exacerbation. Symptoms include coughing, sneezing, itchy eyes, and skin rashes. If anyone in your household is experiencing these symptoms, it’s essential to address the mould issue promptly.

Preparing the Area
Ventilating the Room
Before you start cleaning, ensure the room is well-ventilated. Open windows and use fans to increase airflow. This helps in dispersing mould spores and prevents them from spreading to other areas.
