Mould in carpets is not just unsightly; it poses real health risks and can be a silent destroyer of your indoor environment. Did you know that following water damage, mould can start to form in as little as 24-48 hours​​? This statistic underscores the urgency of addressing moisture issues promptly to prevent mould growth. 

Furthermore, experts recommend seeking professional help if the mouldy area is larger than 3 square feet, highlighting the risks associated with larger infestations​​.

But how can you effectively remove mould from your carpets? Are there preventative measures that can ensure your place remains mould-free? Our blog will dive into these questions, offering clear, concise guidance and actionable tips for tackling mould head-on. From identifying early signs of mould to understanding the best removal techniques.

How Does Mould Grow on Carpets?

Mould grows on carpets when three key conditions are met: moisture, warmth, and organic material. Carpets provide an ideal environment for mould because they can trap moisture easily and offer a rich source of organic material for mould to feed on. Here’s how the process typically unfolds:

  • Moisture: The primary catalyst for mould growth in carpets is moisture. This can come from spills, humidity, leaks, or condensation. When carpets remain wet or damp for more than 24 hours, it creates a perfect breeding ground for mould spores to settle and grow.
  • Warmth: Mould thrives in warm temperatures, typically between 77°F and 86°F (25°C and 30°C). However, mould can grow in a range of temperatures, as long as other conditions (like moisture) are present.
  • Organic Material: Carpets are made from organic materials such as wool, or they can accumulate organic matter like skin cells, food particles, and dust. These materials serve as food for mould spores, allowing them to grow and spread.
  • Mould Spores: Mould spores are always present in the air, waiting for the right conditions to land and grow. Once they find a moist, warm spot on a carpet, they can start to colonise.

Preventing mould growth on carpets involves controlling these factors, especially moisture. Regular cleaning, immediate drying of wet areas, and maintaining an environment unfavourable to mould growth (through ventilation and humidity control) are essential steps to prevent mould on carpets.


How to Remove Mould From Carpets

Removing mould from carpets requires a careful approach to prevent spreading spores and to safeguard your health. Here are detailed steps to effectively remove mould from your carpets:

  1. Safety First

Before you start, protect yourself by wearing an N-95 respirator mask, gloves, and goggles. This will help prevent inhaling mould spores or getting them on your skin.

  1. Ventilate the Area

Open windows and doors to ensure good airflow in the room. This helps reduce the concentration of mould spores in the air while you work.

  1. Vacuum the Affected Area

Use a vacuum with a HEPA filter to prevent mould spores from escaping back into the air. Vacuum the mouldy area of the carpet thoroughly to remove loose spores. Dispose of the vacuum bag or clean the vacuum canister outside immediately after.

  1. Prepare a Cleaning Solution

Mix a mould-killing solution. A common mixture is one part white vinegar to two parts water. For more severe mould, you may use a solution of 1 cup bleach in 1 gallon of water, but be cautious as bleach can discolour carpets.

  1. Apply the Solution

Using a spray bottle, apply the solution directly to the mouldy area. Be careful not to oversaturate the carpet, as excess moisture can worsen the mould problem.

  1. Let It Sit

Allow the solution to sit on the mouldy area for at least 15 minutes. This gives it time to penetrate and kill the mould at its roots.

  1. Blot the Area

After the solution has had time to work, use a clean, damp cloth to blot the treated area. Avoid scrubbing, as this can spread mould spores.

  1. Dry the Carpet Thoroughly

Use fans, dehumidifiers, or open windows to dry the carpet completely. It’s crucial to remove all moisture to prevent mould from returning.

  1. Dispose of Materials Safely

Any cloths or materials used to clean mould should be placed in a sealed plastic bag before being disposed of, to prevent spreading spores.

  1. Check the Area

After cleaning, keep an eye on the area for signs of mould returning. If the mould persists, consider consulting a professional cleaner for deep cleaning or carpet replacement if necessary.

Remember, if the mouldy area is larger than 3 square feet, it’s advisable to seek professional help, as larger mould infestations can pose a significant health risk and may require specialised equipment and techniques to remove safely.

How to Prevent Moulds

Preventing mould in carpets is crucial for maintaining a healthy indoor environment. Follow these steps to minimise the risk of mould growth:

  1. Control Humidity

Keep indoor humidity levels below 60% using dehumidifiers or air conditioners. This reduces the moisture in the air, making it less conducive for mould growth.

  1. Improve Ventilation

Ensure adequate airflow in your indoor area by opening windows when weather permits and using exhaust fans in high-moisture areas like bathrooms and kitchens.

  1. Address Spills Immediately

Any liquid spills on carpets should be cleaned up promptly. Use a dry cloth to blot the moisture and a fan or dehumidifier to dry the area thoroughly.

  1. Use Carpet Underlay

Consider installing moisture-resistant padding under your carpets. This can prevent moisture from reaching the carpet from the subfloor.

  1. Regular Carpet Cleaning

Vacuum carpets at least once a week with a HEPA filter vacuum to remove dust and potential mould spores. Schedule professional carpet cleaning annually or as needed for deep cleaning.

  1. Inspect for Leaks

Regularly check your place for leaks or water damage, especially in areas prone to moisture. Fix leaks immediately to prevent water from soaking into carpets.

  1. Avoid Carpet in High-Moisture Areas

If possible, choose flooring options other than carpet in areas that are likely to be moist, such as bathrooms, kitchens, and basements.

  1. Use Rugs and Mats

Place rugs or mats in high-traffic areas and near entrances to reduce the amount of water and dirt tracked onto carpets. These are easier to clean and dry than wall-to-wall carpeting.

  1. Sunlight Exposure

Whenever possible, allow sunlight into your rooms. Sunlight is a natural mould inhibitor and can help keep your carpets dry and mould-free.

  1. Monitor Indoor Plants

While indoor plants can improve air quality, overwatering can increase indoor humidity levels. Ensure plants have good drainage and are not contributing to excess moisture in your place.

By following these preventative measures, you can significantly reduce the risk of mould growth on your carpets, ensuring a healthier living environment.

Importance of Getting Professional Cleaning Services

While DIY methods can be effective for minor mould spots, there are times when calling in a professional carpet cleaner is the best course of action. Here’s why:

1. Severe Infestations: When mould has spread extensively, penetrated deep into the carpet fibres, or affected the carpet backing, professional intervention is essential.

2. Health Concerns: Those with allergies, asthma, compromised immune systems, or respiratory sensitivities might be more vulnerable to the effects of mould exposure. Professionals have the equipment and expertise to safely remove mould and minimise health risks.

3. Specialised Equipment and Products: Carpet cleaning companies have access to powerful hot water extraction machines, commercial-grade mould removal solutions, and industrial-strength drying equipment. This ensures the deepest possible clean and thorough moisture removal.

4. Mould Spore Containment: Professionals follow rigorous procedures to prevent mould spores from spreading during the cleaning process. This includes using negative air pressure machines, air filters, and specialised cleaning techniques.

5. Underlying Moisture Issues: Experienced commercial cleaners can often identify and help address the source of the moisture problem, preventing future mould growth.

When to Consider Professional Carpet Cleaning:

  • Large areas of mould infestation
  • Mould growth recurring after DIY cleaning attempts
  • Health concerns or sensitivities
  • Lingering musty odours
  • If you’re unsure of the severity of the mould problem

Remember: Prevention is always better than dealing with remediation. By maintaining low humidity levels, addressing moisture issues quickly, and regularly cleaning your carpets, you’ll significantly decrease the chance of requiring professional mould removal services.
