If a corner of your walls is turning black, this is a clear indication that there is moisture or mold present.

This is most likely the result of inadequate ventilation, water leaks, or condensation present in the area. This particular form of discolouration is frequently brought on by:

One of the most frequent types of fungus found inside, black mold (Stachybotrys) thrives in environments that are wet, dark, and humid.

accumulation of condensation, particularly in colder corners when warm air is coming into contact with chilly surfaces.

There are leaks that allow moisture to seep in, and they can come from the roof, the plumbing, or the outside walls.


What causes ceilings to become moldy, despite the fact that they were just erected

The following are the three primary factors that might cause ceilings to get moldy, even if they have been recently constructed:

In the beginning, the homeowner works with interior paint that does not contain an alkaline-resistant primer.

This primer is a white paint that is used as a base layer before the subsequent layer of color paint is applied.

One of the primary effects of the primer that is resistant to alkaline is that it prevents mold and moss from growing on the wall.

Second, the worker is still painting the ceiling surface, despite the fact that it has not yet dried. Because of this, the paint layer on the wall surface may be affected, which will result in a decreased ability to fight mold or moss.

Third, there is the potential of using interior paint of poor quality, which not only does not protect the surface of the wall but also contributes to the growth and development of mold by providing the conditions necessary for its growth.

How to proceed:


Take a look at the origin: Make sure there are no leaks or dampness.


Take measures to improve ventilation by installing exhaust fans, using dehumidifiers, or opening windows.


Get rid of the mold: Make use of vinegar, baking soda, or a cleaning designed specifically for mold, while wearing gloves and a mask.


Make repairs to the insulation: Walls that are not adequately insulated can act as a trap for cold air, which can lead to the accumulation of moisture.

Make a call to an expert: If it is widespread or continues to recur, it may be time to seek the assistance of a professional remediation service.
