“I’ve spotted black mould in my bathroom! What do I do?”
This is a common concern among homeowners and a frequently asked question from our customers. Whilst many homeowners may be alarmed at the first signs of black mould in their bathroom, with proper ventilation, moisture control, and a bit of effort, it can be managed effectively.
Take a look at our practical tips to combat and prevent mould growth.
What is Black Mould?
Black mould is a type of fungus that flourishes in damp, humid areas like bathrooms. It often appears on cooler surfaces where steam condenses, such as painted walls, the grout between tiles, and window ledges. Ignoring mould can lead to more significant problems, so it’s crucial to address it promptly.
Why Are Bathrooms Prone to Black Mould?
Black mould can develop anywhere in the home, but the severity of the problem depends on the level of moisture and temperature. Mould tends to flourish in places where dampness lingers for more than six hours, which allows spores to begin germinating. This means bathrooms are ideal environments for black mould growth due to their high humidity levels caused by daily activities such as showering and bathing, and often poor ventilation which traps moisture in the room.
Without somewhere to go the moisture in the air condenses on cool surfaces, creating condensation on walls and ceilings where mould thrives. Black mould caused by condensation is a prevalent issue in UK properties. Fortunately, it is entirely preventable with minimal disruption.
How Do You Prevent Black Mould?
Here are three simple methods for avoiding the presence of black mould:
Reduce Bathroom Humidity
Ensure your bathroom fan is functional. Switch on the bathroom fan during, and then let it to continue to run for 15 mintues after showering or bathing. If your bathroom doesn’t have an operating fan, then if possible open a window while showering or bathing and then leave it open for a period of time afterwards. This will improve ventilation, and allow steam (mositure in the air) to escape.
Wipe Down Surfaces
After each shower or bath, wipe down surfaces to prevent dampness and mould growth. Wring out the cloth in the sink and avoid drying it on a radiator.
Keep the Bathroom Door Closed
Close the bathroom door. containing humid air prevents it from spreading to other areas of your home. Keeping the door closed until your bathroom is fully ventilated will help reduce overall humidity.
These simple steps can significantly reduce the chance of black mould. Professional assistance may be necessary for severe condensation issues, but lifestyle changes are a great first step.

How Do You Remove Black Mould from the Bathroom?
Preventing black mould is one aspect, but cleaning it is also essential if it has already formed. Unfortunately, simply cleaning visible mould from affected surfaces with a soap and a cloth may not be a long term solution to prevent further growth.
How to Clean Black Mould from Bathroom Ceilings and Walls
Chemical and sterilisation products are effective for removing black mould. There are many DIY anti-mould products such as anti-mould spray combined with anti-condensation paints that can remove existing mould and prevent future growth. Mould can leave behind stubborn stains on surfaces that not all products will remove, requiring specialist treatment or professional services to remove.
Addressing Underlying Causes of Mould and Condensation
While DIY solutions can effectively reduce black mould and prevent recurrent outbreaks in the short term, a long-term fix for persistent cases may require improving your home’s ventilation with mechanical systems such as Positive Input Ventilation (PIV).
What is a PIV unit?
PIV units work by gently ventilating your home with fresh, filtered air from outside, which is distributed throughout the house from a central location, such as a landing or hallway. This process helps to:
- Dilute Moisture-Laden Air: By introducing fresh air, PIV units help reduce the humidity levels in your home, which is crucial in preventing the growth of mould.
- Improve Air Quality: The constant flow of clean air helps to displace stale, damp air, leading to a healthier living environment.
- Control Condensation: By maintaining humidity levels around 55%, PIV units effectively minimise surface condensation, the main cause of mould growth.
Benefits of PIV Units:
- Healthier Environment: Lower humidity levels not only prevent mould but also reduce dust mite populations, improving conditions for asthma sufferers and enhancing overall indoor air quality.
- Cost-Effective: PIV units are energy-efficient, with annual running costs as low as £4.35. They also help reduce heating costs by keeping your home well-ventilated and less humid.
- Long-Term Solution: Unlike temporary fixes, PIV units offer a sustainable solution to mould and condensation problems, ensuring long-term protection for your home.
If you’re struggling with persistent black mould or condensation issues, consider installing a PIV unit.
