How to remove mold from bathroom ceiling

Some things are inevitable in life and unfortunately, molds are one of those things. They can easily turn a beautiful home into a gross haunted house. Moisture and a temperature range of 60-80 degrees are all that molds need to grow and thrive. Bathroom ceilings are most prone to molds because of the high percentage of moisture present. When it comes to molds they have almost 100,000 types but the most common ones found in bathrooms are 5. And fortunately, they can be removed if you follow the steps given below.

But first, let us look at what are those 5 types of molds.

Bathroom mold types

Molds are categorized as allergenic, pathogenic, or toxigenic. Some fungi can be edible such as yeast and mushrooms however, molds are not amongst them and can be very dangerous for your health.

Molds are mainly divided into three categories:

  1. Allergenic: you can get eye irritation, asthma, or skin irritation
  2. Pathogenic: it is often difficult to look for this type of mold and can cause disease
  3. Toxigenic: can cause serious health conditions because of the substances they produce

These are the 5 common types of molds that you need to look out for in your bathroom:


What is Acremonium: This type of mold is typically found in areas of the bathroom where there is water damage. Fortunately, this type of mold is slow-spreading and hence can be easily and timely caught and removed. The color of this mold varies from shades of grey, orange, white, pink, and it begins as a little moist substance and gradually evolves as a powdery matter.

What to do: If you find acremonium in your bathroom ceiling then first of all you should wear a protective mask and gloves because it can be dangerous for your health. Make water and bleach solution to get rid of it. Make sure that the area is properly ventilated as spores from the mold may release in the air and cause health issues. Spray the solution on the mold and with the help of a soft brush scrub it clean.


What is Aspergillus: Aspergillus niger, Aspergillus flavus, and Aspergillus fumigatus are the usual varieties of aspergillus. They have a texture like cotton or wool and vary in colors from yellow-green to blue-green hues. You can get allergenic reactions from this kind of mold and if left untreated the effects can increase to serious health issues like Aspergillosis which is a kind of lung disease.

What to do: Apply a chemical or an antifungal treatment to get rid of it if you encounter aspergillus in your home or bathroom.


What is Aureobasidium: Most commonly found in bathrooms and kitchen aureobasidium varies in color from deep black to softer cream or pink hues. And it typically grows in the tile grout or caulking.

What to do: Be very careful and clean your house thoroughly and often if you want to prevent aureobasidium. And if they do grow never forget to wear gloves and a mask of good quality for maximum protection as the pores can react with your skin or through air passage go to your lungs.


What is chaetomium: This type of mold is typically hard to detect as it usually forms behind the walls under the wallpapers or carpets. Damp and humid conditions like that of a bathroom ceiling provide an ideal environment for the mold to grow. You can get both allergenic and pathogenic effects from chaetomium. Hay fever, asthma, and sinus issues are the most common signs that you may have chaetomium in your bathroom.

What to do: Call a mold removal expert immediately for an inspection and removal if you suspect the presence of the mold.


What is Penicillium: Blue-green, white, yellow, or pink hues, and powdery texture are the most visible signs of penicillium. It has a musty odor and grows where it finds moisture and bathrooms are its favorite thriving place. There is no doubt that penicillin has beneficial properties, however, penicillium can cause allergies, including hay fever and lung inflammation.

What to do: Mix together white vinegar, water, chlorine bleach in a bucket and put the solution in a spray bottle. Spray the solution on your ceilings, let it sit for 15-20 minutes, and with a hard brush scrub them.

What causes mold in bathroom ceiling

High humidity, surface structure, poor lighting, bad air circulation/ poor ventilation, or any fusion of these.

Bathrooms typically are the high humidity zones in the house hence more prone to molds. The water vapors from the steam rise up naturally and condense on the bathroom ceiling which traps moisture. Mold spores when rise with the warm air they come in contact with the moist ceiling surface and can start to reproduce.

Make sure that you reduce the humidity in your bathroom by having a proper ventilation system set up. Especially make sure to open windows and turn on the exhaust fan during and after taking a bath.

Molds also reproduce in dark areas and in shadowy places so make sure that your bathroom is well lit and all its corners receive adequate lighting.

How to prevent mold in bathroom ceiling

Mold is an all too frequent sight we get to see in our homes and is absolutely inevitable. Luckily there are prevention tips that will help you remove these fungi and keep it away from your precious home.

Humidity control

As discussed earlier molds build up and grow in areas that are humid and not properly ventilated. So you should at all times ensure that areas like bathrooms that are more prone to humidity are always properly ventilated and humidity levels are kept below 50%. You can do this by getting a dehumidifier and/or by using an air conditioner.

Repair any leaks

The most common way due to which molds build-up is seeping water because of leakage. You may not get concerned over a few drops of leaking water however keep in mind that the gradual build of moisture continuously in any part of your bathroom will cause the molds to grow. So before that happens get any leaking tap, roof, or pipe repaired.

Tidy out after flooding

If unfortunately any pipe in your bathroom has burst and your bathroom is flooded then you should try to get rid of the water within 48 hours. After you have cleared out the major portion of water from your bathroom make sure to take a dry towel and remove the remaining water. Also using fans to dry out the area quickly to avoid further damage.

Ventilate areas prone to water

Areas such as bathrooms need maximum ventilation because the steam from a hot bath can cause a lot of damage due to mold build-up. So always remember to turn on the exhaust fan when taking a shower until all the steam is gone.
