How to Prevent Mould Growing on Wooden Window Frames

Plastic and metal window frames have become more and more popular recently, but for those who want a traditional, warm look, there's really no better choice than classic wood frames.

It's not just their aesthetic appeal that makes wooden frames a great choice, though. They also give your home excellent insulation, and they're strong and durable. With all these benefits, it's no surprise that wooden window frames have managed to retain plenty of popularity.

There's one drawback some people face with their wooden frames, however: mould. It shouldn't put you off having real wood, though. Just follow these tips and keep your frames clean and free from mildew and mould.

Get rid of any existing mould

Before you begin preventing the growth of mould, you'll need to make sure there's none already on your window frames. Look closely, as it's not always obvious, especially on dark surfaces.

Give the windows and frames a good clean using a soft cloth and a 50/50 bleach and hot water solution. When you've finished, let the frames dry out completely.

Reduce moisture

If there's moisture, there's a good chance there will be mould. All sorts of fungal growths need water to grow, and getting rid of this water can stop them in their tracks.

Windows are prone to condensation, and wooden frames are porous, leading to potentially serious problems with damp. It's easy to keep them dry, however.

Keep your windows open whenever the weather allows; this will keep air circulating and prevent condensation building up. You should also make sure your home is at a comfortable, warm temperature – but not too hot, as this increases condensation and encourages mould growth.

If you're struggling to keep the frames dry, place a small dehumidifier on each windowsill to absorb moisture from the air.

Treat the wood

When you paint or varnish your window frames, choose a product with anti-mould properties. These are widely available, and highly effective. Remember to reapply the coating periodically as it wears away.

Although this will give you a good deal of protection against mould, don't assume it will always stop it completely. You should still put effort into maintaining a dry area to help inhibit growth.

Keep an eye on the timber

Inspect your window frames every now and again for signs of mould, damage, or wear. Any small cracks can increase your chances of mould growing, as they provide damp pockets that are difficult to dry out.

If you spot mould beginning to grow, tackle it quickly with bleach and water and you should be able to stop it getting any worse.
