Types of Mold in Basement Ceiling
There are a variety of different types of mold that can be found growing on or in your basement ceiling. The three main types you will often see are white, black, and green molds.
White mold is a term most commonly used to describe a mold white in appearance or with a powdery-like texture. cladosporium, penicillium, and aspergillus are the 3 main types of mold found in this category.
White mold can often mean the spores of the mold have no pigment and that is usually decided by the type of material or surface that the mold is growing on.
It’s important to note however that these species can also be found black and green in color, once the spores mature and develop their pigmentation.
Black mold is considered to be the most toxic form of mold, because it can produce mycotoxins harmful to human health, and should therefore be dealt with immediately when discovered.
Stachybotrys chartarum is the technical name for black mold, and comes with a very distinct musty smell that is noticeable right away.
Bathrooms and Basment ceilings are the most common places this mold can be found due to condensation, and it’s often caused by:
- Excessive humidity or warm temperatures
- Poor insulation of your Basement
- Dampness/Liquid moisture
- Long periods of darkness
- Water leakage
Green mold is soft & fuzzy or even powdery in appearance, and may closely resemble something such as moss.
Cladosporium, Aspergillus, and Penicillium are the most common forms of green mold after maturing, which also hold the potential to be slightly different in color with blue-green hues, or even olive green.
These molds still hold the potential to provide mycotoxins and be harmful to your health, it’s important to take care of them as soon as possible on your Basement Ceiling!
Why is there Mold on my Basement Ceiling?
Mold can often be found growing on your basement ceiling for one of two reasons; too much humidity in the air, or too much liquid moisture in the structure of your basement.
How to Remove Basement Ceiling Mold
You can remove basement ceiling mold in just a few steps if done properly.
- Remove the source of moisture from the basement ceiling. If you’ve noticed a leak, or an increase in humidity in your basement, it is crucial to remove this moisture source as soon as you possibly can.
A dehumidifier can tackle an increase in humidity, as well as proper ventilation (an open window or running fan system).
Should you come across a leak from a pipe or other water source, patch it to prevent any further moisture from getting onto your ceiling.
If you are unable to provide patchwork yourself, you may want to consult a professional about having them seal the leak or water source for you.
- Remove all visible mold growth & material. If you have a ceiling that is easily replaceable and not load bearing, such as ceiling tiles, it can be replaced with new material and swapped out to get rid of the bulk of the mold in a smooth transition.
Be sure to wear proper eyewear, a mask, and gloves at the minimum to reduce your exposure to the mold when performing tasks.
- Manually clean moldy material that cannot be easily replaced. Mold can be killed off with certain substances like bleach or vinegar.
You can use a mixture of one part bleach to ten parts water as a cleanser to eliminate mold by covering the affected area thoroughly. Wipe or scrape away the mold after allowing the bleach solution to set in.
Put vinegar in a spray bottle and spray the mold affected area down. Allow the vinegar to sit on the mold for at least an hour. Wipe the area down clean with water afterwards, but ensure no moisture remains following the removal of the mold.
If after you have completed these steps and mold is still present, you may need to contact a professional in order to get it removed completely.
