What is mold?

Ever walked into your basement only to be greeted by some displeasing grey patches on some part of the walls? Of course, you would wonder how they got there since they weren’t there a day before, or maybe they were, and you just took notice. 

So what exactly is this unwanted slimy, fuzzy patch? Well, molds!

Mold is a living organism, and they make up a part of the kingdom of fungi. They are microbes or fungi that grow in the form of hyphae. The growth of these hyphae results in a stained, hairy, or misty appearance. 

Also, Mold feeds on organic matter, which explains its presence on surfaces like woods and drywalls. 

These microorganisms can be found outdoors and indoors. Although, they are usually not a problem, when left unchecked, can result in the following:

  • Damage to buildings.
  • Stained walls.
  • Rotten woods
  • Triggered attacks in allergic individuals.

How does mold get into a basement?

Moisture is the primary factor that causes molds in basement areas. Other reasons include

  • Leaks and cracks in foundations.
  • Precipitation.
  • Leaks in walls, roofs, and pipes.
  • Poor ventilation.
  • Wet clothing in basements.

Easy ways to identify a mole in a basement

Trying to locate a mold in a finished basement can be tasking because molds can hide behind finished surfaces and even drywalls. Here are tips to help you out.

Earthy smell

The first culprit to identifying a mole in the basement is its smell.  Mold produces compounds known as microbial volatile organic compounds. These compounds usually have an unpleasant smell and are often tied to the musty odor of molds. So, if any area has a musty or earthy smell, that’s a sign that there may be some molds present there. 

Colour

Molds appear as fuzzy patches with yellow tints. Discoloration on your walls may also be indicating a mole problem.

Use a bleach

To test for molds in your basement, dab some drops of beach on the dark or misty area. If the area lightens after a few minutes, that’s a clear indicator that you have mold. However, if the area remains dark, then it’s just dirt.

Moreover, look out for areas that may have been exposed to a lot of water.
