Not sure whether or not you have it in the house? Want to know how to tell if you have mold? If so, be sure to read the rest of the post.

What Is Mold? 

Mold is a type of fungus that is present almost everywhere. For example, it can grow around windows, roofs, or pipes—anywhere where there’s a lot of moisture.

Appearance-wise, they may appear white, black, orange, or purple. At the end of the day, it depends on the species.

How to Tell If You Have Mold: 5 Things to Look For 

Think your house might have a mold problem? Here are a few signs to look for.

1. Water Leaks 

Is there a water leak somewhere in the house? If so, there’s a high chance that there will be mold. After all, they thrive in wet environments.

Watch out for bulging walls or cracks in the wallpaper—those are signs that there may be mold under the surface.

2. Strange Odors 

Mold is often associated with a musty, earthy odor. If anything, it’s similar to what you’d smell after opening an old book; it’s definitely noticeable.

If you notice anything like that, call a professional. Chances are, there is mold present.

3. Health Problems 

Exposure to mold can affect your health in various ways. For example, it can cause sneezing, coughing, or skin irritations. In some cases, it can also trigger asthma.

Given that, it’s important to get your house treated right away if you experience any of the above symptoms. Consider spending more time outdoors as you prepare

4. Visible Mold Growth 

Visible mold growth is a telltale sign that there’s a problem. Even if the patch is small, you want to take immediate action. The longer you wait, the more it will spread.

Depending on the type of mold, it may appear as clusters of small spots or furry growths.

5. Condensation 

Mold tends to grow where condensation builds up and collects. For example, it can grow on glass windows and pipes. If that’s the case, you’ll want to get the humidity level under control—the excess moisture will only feed the mold spores.
