Mould is commonplace in the home so it’s no surprise that many homeowners ask: how do I stop mould in my built-in wardrobe?

Your closet can be filled with everything, from your everyday essentials to your glamorous gowns. But, one thing you never want to find in your wardrobe is mould.

The mildew in fitted wardrobes is usually caused by two main factors: condensation and damp clothing. We have put together this guide to help you keep your closet dry and ventilated so that you never have to deal with this awful wet rot.

What is mould and why is it a problem in built-in wardrobes?

Mould is a type of fungus that is produced in humid and damp conditions. Built-in wardrobes are more susceptible to it as they can contain warm air, moisture from semi-dry clothes and material for the fungus to feed on such as wood, carpet and fabric.

Unfortunately, mildew will continue to develop in a closet until it is removed. As it multiplies, mould can become a health hazard, so great care is needed when getting rid of it.

In severe cases of damp, your fitted wardrobes would need to be pulled out entirely so that the walls can be treated before a new built-in wardrobe is installed.

Apart from structural damage, the fungus can ruin all the clothes that it comes into contact with. Since garments are either on top of or next to each other in a closet, it is easy for the mould to spread to your entire collection.

How to identify mould and what are the symptoms?

The most obvious sign of mould in your bespoke built-in wardrobe will be its visible presence. If you begin to see green, black or white fungus growing on your walls, floors, carpets or on clothing, then you definitely have a problem.

Unfortunately, not all mould is visible, or it may be growing in areas that are hidden. The following are further signs that you can look out for if you suspect the presence of this wet rot in your room.

An unmistakable and unpleasant odour that is musty, earthy, or cheesy.
Increased relative humidity levels in the closet.
The walls inside the wardrobe feel cold to the touch.
The walls or closet ceiling have noticeable spots that look different from the surrounding surface.
You or your family members begin to experience unexplained health issues such as allergic reactions, respiratory issues, and headaches.

Upon identifying any of these signs, we recommend calling professionals who will run air tests to confirm the presence of the fungus and work to identify the source.

The best ways to prevent mould from growing in your wardrobe

Mould needs moisture to grow, so getting rid of dampness stops it from multiplying in your wardrobe. As such, it’s best to keep the humidity in your wardrobe below 60%. An easy solution for this is to install a humidifier. This will regulate moisture in the air ensuring it never accumulates to unwanted levels.

It may not always be easy to identify the source of the dampness in your wardrobe. As a starting point, check for possible leaky pipes. Chances are your closet has bathroom or kitchen pipes running through its walls and these could be faulty.

Leaky roofs and gutters are also common culprits, as are leaking attics. Once you identify a leak, seal off any cracks and openings that allow moisture into your closet.

Lastly, empty your wardrobe regularly and use a fungicide to kill off any developing mildew. Always remember to check for safety precautions when using any chemicals.

How to clean up mould if it's already present?

Mould can be toxic, so we recommend calling professionals to get rid of it. However, if you have a small affected area that you feel you can manage on your own, please attend to it while wearing a mask, gloves and protective goggles.

To begin, wash all mildew-stained clothes with detergent and dry them thoroughly in the sun. Toss any items that are beyond saving.

As for the fitted wardrobe, empty it out and spray the entire closet with white vinegar. Let it sit for half an hour before you proceed to scrub the walls with detergent and thoroughly vacuum and clean the floor.

Once all the cleaning is done, leave a fan to run for 24hrs in the closet. This is a crucial step that will ensure that no moisture is left behind from the cleaning. Repeat this process weekly for a month to eliminate all traces of the fungus.

Here are some effective tips to prevent mould growth or controlling its growth:

Keep It Clean: Regularly clean your wardrobe, removing any dust or debris that may attract moisture and mold spores. Wipe down shelves, hangers, and walls with a mild detergent or vinegar solution to discourage mold growth. It is also a good habit to regularly clean your wardrobe with a mould spray, as it is easily available these days.
Declutter and Organize: A cluttered wardrobe can impede airflow, leading to trapped moisture. Organise your clothes and accessories to ensure proper ventilation and make it easier to spot and address any potential mold issues.

Invest in Moisture Absorbers: Silica gel packets, dehumidifiers, or moisture-absorbing charcoal bags can help reduce excess humidity inside the wardrobe, inhibiting mold growth.
Use Desiccants: Desiccants are substances that absorb moisture. Placing items like chalk, baking soda, or uncooked rice in small containers within your wardrobe can help keep the air dry.
Install Wardrobe Ventilation: Consider installing small vents or ventilation systems to allow better airflow and prevent the accumulation of moisture in the wardrobe.
Check for Leaks: Regularly inspect your home, including the area around the wardrobe, for any leaks or water damage. Addressing these issues promptly will help prevent mold from finding a foothold.
Use Mold-Resistant Materials: When renovating or purchasing new wardrobes, opt for materials that are resistant to mold growth, such as cedar or moisture-resistant laminates.
Don't Store Damp Clothes: Avoid putting wet or damp clothes directly into the wardrobe. Ensure they are thoroughly dry before storing them to prevent moisture buildup.
Leave the Doors Open Occasionally: If the wardrobe is prone to humidity, leave the doors open for some time each day to allow for air circulation and prevent moisture buildup.

Summing Up

Keeping your wardrobe dry and well-ventilated will prevent the build-up of mould. If you, unfortunately, already have a mildew problem, attend to it immediately, preferably with the help of professionals. If left untreated, mould will cause damage to your clothes, your wardrobe and ultimately, your health.

So the best strategy is to stay alert and address the problem at the first sign, particularly in the winter months.
