Black Mildew vs Black Mold l Top 5 Differences

There are few things a homeowner likes to see less than that cloudy, fuzzy blackness of mold. However, not everything that looks that way is actually black mold. What your house might have is black mildew.

They sound pretty similar and they’re not only alike in name.

But what is the difference? How can you be sure your walls are covered with one or the other? Don’t worry, we have the answers you’re looking for.

We’re going to settle this – black mildew vs black mold – what separates them and how you can differentiate between the two.

Let’s get right to it!

Black Mildew And Black Mold – The Similarities

Before we explain the differences between black mildew and black mold, we want to explain why these two terms are being used interchangeably so often.

First and foremost, both mold and mildew belong to the family of fungi.

Furthermore, they both need a similar environment to grow and thrive: moist. As far as temperature goes, most types of mold and mildew can appear at different temperatures, while some require higher ones.

Both mildew and mold thrive on similar materials, primarily those containing cellulose, such as paper, drywall, and wood. However, they are not limited to these materials and can grow on various other surfaces under the right conditions.

Lastly, they both have a strong, unpleasant smell. However, those familiar with the smell of black mold could find a slight difference between the two.

Black Mildew Vs Black Mold – The Differences

For the layman, these two types of fungi occupy the same spot, they mean the same thing. However, if you think you’ve got one in your home, it’s important to identify which, because health risks and treatment for each differs.

1. Appearance

Black mildew is typically flat with a dusty appearance. It needs moisture more than mold does, which is why it’s mildew that’s found in showers most often. 

Mold, on the other hand, is fuzzy and raised, with a pronounced texture.

2. Growth Pattern

What’s more, the way they grow is also different.

Mildew starts out in a few dots which then spread outward, and remains on the surface, while mold is much more aggressive in the way it grows – inward and upward, causing it to progressively eat at walls and ceilings.

3. Smell

As we’ve mentioned previously, they both have a strong smell to them, but you can tell them apart.

Mildew has a distinct, strong, musty smell, while mold is more pungent to the nose.

4. Health Effects

Mildew, much like mold, can cause some respiratory issues, such as coughing fits, but they are generally mild and benign.

On the other hand, the impact of black mold can be more severe, causing more or less intense allergic reactions, as it’s more aggressive and pervasive.

5. Treatment

Mildew is much easier to clean and get rid of yourself, while mold typically requires professional help to be gone entirely.

If you do opt to exterminate mold yourself, you will need to take more precautions and protective measures, and you’ll need more equipment and time.
