Why Mould on Ceilings Is a Red Flag
Mould on your ceiling isn’t just ugly, it’s a warning sign. Whether it appears in your bathroom, bedroom, or living room, mould indicates excess moisture, poor ventilation, or underlying water damage.
Mould exposure can cause serious health issues, including:
-
Allergies
-
Asthma
-
Breathing difficulties
-
Skin irritation
If you’re a tenant and mould has appeared due to your landlord’s failure to fix structural issues, you may be eligible to start a housing disrepair claim. But first, let’s look at how to remove it properly and safely.
What Causes Mould on Ceilings?
Understanding what’s behind the mould helps you fix the problem permanently. Common causes include:
-
Condensation: Especially in poorly ventilated bathrooms or kitchens
-
Leaking roof or pipework: Water damage that seeps into the ceilings
-
Rising damp: Moisture travelling up from walls into ceiling corners
-
Steam and humidity: Frequent in bathrooms without extractor fans
If the mould keeps returning, the issue is likely structural, and your landlord may be responsible for fixing it.
How to Get Rid of Mould on Ceilings – Step-by-Step
Step 1: Protect Yourself and the Room
Before cleaning:
-
Wear gloves, goggles, and a face mask
-
Open windows for ventilation
-
Cover furniture and floors with plastic sheets
Mould spores can be hazardous—don’t take risks.
Step 2: Choose a Safe Cleaning Solution
Here are your options:
-
White vinegar: A natural antifungal
-
Hydrogen peroxide (3%): Kills spores and sanitises
-
Commercial mould removers: Specifically formulated for ceilings
-
Baking soda and water: A safe option for mild cases
-
Bleach solution: Use only in well-ventilated rooms (1 part bleach to 3 parts water)
Avoid mixing cleaning products, and always test on a small area first.
Step 3: Apply and Let It Soak
-
Use a spray bottle or sponge to apply your solution
-
Let it sit for 15 to 30 minutes to kill the mould
-
Avoid scrubbing immediately, as it may release spores
Step 4: Scrub the Mould Away
Once the solution has soaked in:
-
Use a non-abrasive sponge or cloth
-
Gently scrub until the stain lifts
-
Repeat if necessary for stubborn patches
Step 5: Dry the Area Thoroughly
Use a fan or dehumidifier to dry the ceiling completely. This helps stop mould from returning.
If paint or plaster has been damaged, consider repainting with mould-resistant ceiling paint once the area is fully dry.
What Not to Do
-
Don’t just paint over mould – it will come back
