How to Remove Mould: A Complete Guide to a Healthier Home

Mould isn’t just an eyesore—it’s a problem that can affect your health, your home, and your overall quality of life. Left untreated, mould can trigger respiratory issues, allergies, and even infections. Beyond health risks, mould can damage walls, fabrics, furniture, and soft furnishings. That’s why mould removal should be at the top of your home improvement checklist if you notice it starting to spread.

In this guide, we’ll explore how to safely tackle mould in different areas of your home, from walls to bathroom grout, and share essential mould prevention tips to keep it from coming back.

Staying Safe During Mould Removal

Before tackling any mould, make sure you protect yourself. Even small amounts of mould release spores into the air, which can aggravate your lungs.

• Wear protective gear: Always use a mask that covers your nose and mouth, long rubber gloves, and eye protection when handling mould sprays, bleach, or vinegar.

• Ventilate the room: Keep windows open to improve airflow, but close doors to stop spores spreading through the rest of your home.

• Know your limits: This guide is intended for small patches of mould (less than one square metre). If you’re facing widespread mould across multiple rooms, it’s time to call in a professional.

Removing Mould from Walls

Walls are one of the most common places for mould to appear, particularly in damp or poorly ventilated rooms. If your walls are made from plasterboard, be aware that mould can penetrate deep into the material. In severe cases, you may need to replace affected sections.

1. Using Mould Sprays

Specialist mould sprays are widely available and designed to kill spores effectively. Always follow the manufacturer’s instructions, and don’t forget your protective equipment.

2. Bleach Solution

If you don’t have mould spray on hand, bleach is a strong alternative. Mix one part bleach with four parts water, gently scrub the affected area, then wipe clean with fresh water and dry thoroughly.

3. White Vinegar

For a natural solution, mix equal parts vinegar and water in a spray bottle. Spray the mould, leave it for an hour, then wipe with a damp cloth. Vinegar is especially useful in spaces where you’d prefer not to use harsher chemicals, such as children’s bedrooms or kitchens.

Removing Bathroom Mould from Sealant & Grout

Bathrooms are hotspots for mould thanks to constant moisture. Bathroom mould commonly forms around sealant and grout lines, making it tricky to clean.

• Try specialist bathroom mould cleaners designed for tiles and grout.

• For stubborn mould, consider re-grouting or replacing the sealant entirely.

• Once clean, keep your bathroom well-ventilated by using extractor fans or opening windows after showers.

Removing Mould from Fabric

Mould doesn’t just affect hard surfaces—clothes, curtains, and soft furnishings are also at risk.

1. Fill a bucket with water and add 1–2 cups of white vinegar.

2. Soak fabrics for at least an hour.

3. Gently scrub the mould with a toothbrush while wearing protective gloves.

4. Wash items on a regular cycle, adding extra vinegar if stains are heavy.

5. Dry fabrics outside in fresh air for best results.

Avoid using bleach on fabric as it can ruin colours.

Removing Mould from Furniture

Wooden furniture can also become a breeding ground for mould, especially if it’s kept against damp walls.

1. Move the furniture outside to stop spores spreading indoors.

2. Vacuum the surface carefully, then clean the vacuum filter.

3. Mix washing-up liquid with warm water, spray the area, and scrub with a soft brush. Dry with a towel.

4. If needed, apply a vinegar and water solution, leave for an hour, then wipe clean.

5. If mould persists, sanding and refinishing may be necessary.

Mould Prevention: Stopping Mould Before It Starts

Effective mould removal is only half the battle—mould prevention is just as important for long-term results. Here are some simple home improvement steps to keep your home mould-free:

• Control humidity: Use dehumidifiers in damp rooms and ensure proper ventilation in kitchens and bathrooms.

• Fix leaks quickly: Leaky pipes, roofs, or windows can lead to persistent dampness that mould loves.

• Improve airflow: Keep furniture a few inches away from walls to allow circulation.

• Use anti-mould paint: Once your walls are clean and dry, repaint with an anti-mould paint to create a protective barrier.

Final Thoughts

Mould removal might feel like a daunting task, but with the right approach and safety precautions, you can restore your home and protect your health. From using mould sprays on walls to soaking fabrics in vinegar, the right method depends on the material you’re treating. Remember, consistent mould prevention practices such as ventilation and moisture control are key to ensuring your home stays mould-free.

If the mould problem in your home is extensive or keeps returning, don’t hesitate to contact a professional for advice. After all, investing in mould prevention is one of the most effective home improvement steps you can take to safeguard both your living space and your wellbeing.
