Atlanta Mold Removal: Sources Of Mold In Your Home


If you want to stop a mold infestation from taking hold in your home, it’s usually a good idea to know where mold comes from in the first place so that you can take preventative measures after Atlanta mold removal is done doing their work.

In this guide, we’re going to look at some of the most common reasons why mold may have decided to take root in a house.


Mold Spores

First, it’s important to understand where mold comes from. As a fungus, mold spreads using spores, much like mushrooms. These spores are prolific and they are present worldwide, so it can be extremely difficult to prevent the spores themselves from taking hold, but you can create an environment that they don’t like.

Most commonly, spores get into a house through air movement, as mold spores are light enough to float on the air. In rare cases, you may run into mold that has spread through the introduction of contaminated materials to a house, such as bringing in wood that already had mold on it, or tracking in dirt that was infested with mold.



You’ve likely heard about how moisture is one of the most attractive things to mold. Like any other kind of life on earth, water is required to keep mold alive, and mold typically requires relatively high humidity. However, mold works slowly, so short periods of high humidity aren’t suitable for it.

If you have a part of your house that’s humid for an extended period of time, then it’s pretty likely that mold will find its way there sooner or later. You don’t even need standing water to get mold to start growing, as enough humidity in the air may end up being enough for it to grow and thrive off of.


Lack of Sunlight

Mold grows in darkness because direct sunlight is deadly to it. The UV rays that you’ll find in sunlight will break apart mold’s cells, much like gamma radiation will do to a human being. This is typically why mold only grows in dark places in nature, like on the underside of rocks and fallen trees.

While indoor lighting isn’t quite as damaging to mold, mold has evolved to avoid light altogether, so you’re likely to find it in darker parts of your home. While there are light bulbs that emulate the sun’s light, it’s pretty unfeasible to keep every part of your home lit at all times.


Food for the Mold

The mold also needs something to feed off of and grow, and this is where the organic materials that go into building a house come into the equation. In most cases, mold will feed off of the wood that is present in your building’s supports and walls.

However, mold doesn’t necessarily need to feed on wood to survive. Mold can even survive off of insulation and the gypsum that is used to make drywall. Mold can also eat away at clothing and luggage and even residue on tile surfaces.
