Mould on Windows: Causes and Solutions

Mould is a variety of fungus that grows in wet, dark environments. Throughout winter, air-borne beads of water can come into contact with the cold, glass surface of your windows and settle. This provides mould spores with the environment they require to flourish. This is terrible news for your windows, and it isn’t helpful for your health, either.

Can Mould on Windows Make You Sick?
If mould is enabled to accumulate, it will certainly look pretty revolting– however does that always indicate it’s unclean, or perhaps dangerous?

For asthmatics and those suffering from allergic reactions, the response is a guaranteed yes. Mould reproduces by launching microscopic spores into the air. If there’s enough mould on your window sill from condensation, then you’ll have a problem.

Even for those people who aren’t impacted by asthma, direct exposure to mould can lead to irritation of the eyes, skin, and lungs. The effect of prolonged direct exposure to mould is even more extreme. For this reason, utilise a mask and gloves while you’re cleaning it up, and make sure that the area is well-ventilated. On that note, let’s look at how to clean up mould off window frames and sills.

How to Get Mould off uPVC Windows
Cleaning up uPVC requires a mild technique. An abrasive cleaner can permanently (and quite quickly) discolour the plastic.

Excellent outcomes can be achieved with a combination of water and vinegar, at a ratio of around 4:1. Load the solution into a spray can and douse the affected location prior to wiping dry. The acids present in the vinegar will break apart the mould, enabling it to be easily scrubbed away.

How to Get Mould off Timber Windows
Now let’s take a look at how to get rid of mould from wood window frames. Timber will respond to moisture a little differently to artificial materials. Rather than resting on the wood, those small water molecules will permeate in between the fibres– which is why regularly treating your wood windows is so crucial.

You’ll want a various cleansing service depending on whether your window is finished or incomplete. In the latter case, vinegar, baking soda, or a mix of home detergent and water will work. Unfinished wood may need a more caustic service, because the mould might have permeated into the grain. Rubbing alcohol is usually an excellent place to begin.

How to Get Mould off Aluminium Windows
Given that aluminium carries out heat better than lumber or uPVC, it will get chillier. This indicates more condensation, and as a result, more mould. However unlike uPVC, you can securely clean aluminium windows with bleach.

It’s easy to eliminate mould from aluminium window frames using a combination of bleach and water, at a ratio of around 1:10. Spray onto the afflicted location and await the bleach to disintegrate the mould prior to rinsing. When you’re done, dry the window quickly to prevent the mould from returning.
