Most of the time, people ask us what they should do about the black mould problem in their bathroom. Many people fear seeing the first sign of black mould, but this problem can be easily remedied. In the UK, it is estimated that over 1 million homes have a problem with damp and mould.

Mould is a common problem primarily generated in the bathroom, which causes a foul smell and affects your lungs while inhaling. Mould is caused by poor ventilation in the bathroom, so the air and moisture generated by the hot water cannot escape, settling on walls and ceilings and forming black mould. This is a widespread problem in homes in the UK and can be cured with minimal disruption

What is black mould?

Black mould is a fungus that grows inside your house in humid and damp environments. It appears mostly in black, which is why it is known as black mould, and often grows on ceilings, walls, and other surfaces. It is also dangerous to health due to the presence of mycotoxins, which can cause respiratory problems, allergies, and other health problems.

According to a study by the World Health Organization, exposure to mould indoors can cause respiratory symptoms, allergies, and asthma.

When the mould is disturbed during cleaning, these toxins are released into the air and can enter your respiratory system through inhalation. The presence of black mould in a home can reduce its value by up to 30%, according to a study by the University of Connecticut.

Therefore, it is essential to treat this problem as soon as possible before it spreads further and causes health problems. Professional help may be necessary to remove the mould and prevent it from recurring.

What causes black mould in the bathroom?

The presence of excess moisture and humidity often leads to black mould in the bathroom. The bathroom is a prime location for black mould growth due to poor ventilation, high humidity, and other factors. Some of the leading causes of black mould development in the bathroom include:

Poor ventilation

When there is poor ventilation in a room, the air and moisture generated by daily activities, such as cooking, showering, and washing, cannot escape. This can cause humidity levels to rise, creating an environment that is ideal for black mould to grow.


Leaky pipes, taps, or shower heads can cause water to accumulate in the bathroom, creating a damp environment for mould growth.

Moisture-rich surfaces

Porous materials, such as shower curtains, rugs, and towels, can trap moisture and promote mould growth if not regularly washed and dried.

Poor cleaning habits

If the bathroom is not cleaned on a daily basis, mould spores can accumulate and grow on damp surfaces.

Lack of natural light

Mould thrives in dark environments, and bathrooms without windows or natural light can encourage mould growth.

Addressing these underlying causes is crucial to prevent black mould growth in the bathroom. Regularly cleaning and drying surfaces, improving ventilation, repairing leaks, and using a dehumidifier or fan can help prevent and avoid mould growth in the bathroom. If you notice mould growth, it is important to address it promptly to prevent it from spreading and potentially causing health problems.

What are the solutions for black mould?

The most effective solution for black mould is to prevent it from growing in the first place by controlling moisture and humidity levels in your home or workplace. If you do discover black mould growth, there are several steps you can take to deal with it, including:

Identify the source of moisture

Black Mould thrives in damp environments, so the first step is to find the source of moisture and fix any leaks or water damage.

Use protective gear

If you decide to clean the Mould, wear protective gear, such as gloves, goggles, and a respirator, to avoid inhaling or touching the Mould.

Clean the affected area

Use bleach and water or a commercial mould cleaner to scrub the affected area thoroughly. Be sure to let the area dry entirely afterwards.

Discard heavily contaminated materials

If the Mould has spread to porous materials, such as carpets or drywall, it may be necessary to discard them and replace them with new materials.

Improve ventilation

Improving ventilation and air circulation in the affected area can help decrease humidity and stop mould growth.

Hire a professional

In some cases, hiring a professional mould remediation company may be necessary to remove the Mould and ensure it doesn’t return. It’s vital to take black Mould seriously and address it promptly to protect your health and prevent it from spreading.
