Don’t Ignore the Spore: How Algae and Mould Can Affect Your Windows

Windows are a fragile yet effective barrier between the outside and our indoor comfort. We expect them to get dirty and accumulate all kinds of environmental debris. Dust and pollen are easy to remove using standard tools and supplies. However, suspicious green or coloured growths should raise the alarm as they might indicate mould or algae.

In this post, we take a look at everything you need to know about mould and algae around your house and how to fight these hazards.

What’s the Difference Between Algae and Mould?

Mould and algae are different organisms, and the methods to remove them similarly differ.

Algae are similar to plants as they use chlorophyll to process sunlight. This gives them the characteristic green colour you might notice on damper areas of your home. They can also thrive on windows that are out of direct sunlight, making them dirty-looking and affecting the framing, especially with timber windows.

Mould is a fungus that multiplies through spores and is airborne like algae. Unlike the latter, mould can cause health problems and will likely spread inside your home. Mould is more dangerous than algae and more stubborn.

The Dangers of Mould

Once exposed regularly to mould, you might find that your health starts to get affected. Mould can produce irritant and sometimes toxic substances that emanate in the air, causing issues like breathing problems, skin rashes, allergies, and even intoxication. Mould, especially black mould, can trigger asthma attacks, strong allergic reactions, and other health problems.

What Causes Algae and Mould to Grow on Windows?

Windows are one of the areas most prone to mould or algae because of the constantly fluctuating temperatures and high moisture. Sometimes, condensation occurs, which creates a favourable environment for these organisms.

Some of the most common places for mould and algae growth include:

• Windowsills: because of the moisture and dust trapped in the crevices on the sill, you can get mould or algae growing here.
• Caulking: algae feeds on lime and other minerals and might thrive around your windows.
• Between glass panes: if dust gets trapped between the panes of double-glazed windows, it can create an ideal environment for mould or algae to grow.

Ridding Your Windows of Algae and Mould

The best way to keep your windows algae and mould-free is to prevent them. One way of doing this is to ensure your home has proper insulation, ventilation, and heating. It is also crucial to clean your windows properly. Pressure washing can also be an efficient way of removing mould and algae.
