How to Remove and Prevent Bathroom Ceiling Mould Effectively

Why Does Mould Build Up in Bathrooms?
Let’s face it—mould in the bathroom is something most of us have dealt with at some point. It usually shows up on the ceiling, around windows, and especially near silicone seals in showers, baths, and sinks. Why? Bathrooms are full of steam, heat, and moisture—the perfect environment for mould to grow, especially when there’s not enough ventilation.
What Is Mould, Exactly?
Mould is a type of fungus that thrives in damp, poorly ventilated spaces. It can look like dark spots, patches, or streaks—most commonly black, grey, or green. It’s not just unpleasant to look at, it can also trigger allergies, irritate skin, and make your bathroom feel unclean.
How to Remove Bathroom Ceiling Mould
If you've spotted mould on your bathroom ceiling, it's important to act fast. Here’s a simple, effective way to tackle it:
What You’ll Need
Protective gloves
Safety goggles (optional, but a good idea)
Mask or face covering
Mould remover spray or a mix of white vinegar & water
A sponge or soft cloth
Ladder or step stool if needed
Step-by-Step Cleaning
Ventilate the room – Open windows and turn on the fan if you have one.
Apply your mould remover – Spray directly onto the mouldy areas and let it sit for 10–15 minutes.
Scrub gently – Use a sponge or cloth to wipe away the mould. Be gentle to avoid damaging paint or plaster.
Rinse and dry – Wipe down with a clean, damp cloth. Then dry the area fully with a towel.
How to Prevent Mould Coming Back
Once mould is gone, keeping it away is key. Here’s how you can stop it from coming back:
Improve Ventilation
Keep a window open during and after showers, or install an extractor fan if you don’t already have one.
Use a Dehumidifier
If your bathroom is particularly damp, a small dehumidifier can reduce moisture and discourage mould growth.
Regularly Clean Silicone Seals
Mould loves to grow in cracked or worn silicone. That’s where we come in.
When to Reseal Your Bathroom with Fresh Silicone
Old, mouldy, or cracked silicone around your bath, shower, sink, or tiles can make mould worse. It traps water, loses its seal, and creates the perfect place for mould to hide.
Signs You Need a Reseal:
Dark mould stains that won’t clean off
Cracked, split or peeling silicone
Water escaping from shower or bath edges
Damp or musty smells

FAQs About Bathroom Mould
Is black mould in the bathroom dangerous?
In small amounts, mould is more of an irritant than a health hazard. But if it keeps coming back or starts to spread, it’s best to remove it and fix the cause.
Can I paint over mould on the ceiling?
Not really. Paint won’t stop mould from growing—it’ll just cover it up for a while. Always remove mould first and make sure the surface is dry before repainting.
What’s the best silicone to use in a bathroom?
Always choose anti-mould sanitary-grade silicone. This is the type we use at Neatly Done—specially designed for bathrooms and wet areas.
