If you think that mildew and mold are the same thing, you’re almost right:
Mildew is a type of mold, but not all molds are mildew. The fungi thrive in moist environments, and they live on all kinds of surfaces, so they’re both housecleaning headaches.
While excessive mildew can cause health problems, it doesn’t have the toxic power of mold. Before you go after that splotch on the baseboard, you need to know the difference.
It is just plain mildew or something that needs attention from a mold remediation specialist?
You can answer that question with a little household bleach:
Just dab a few drops on the suspected area, and wait several minutes. If it becomes lighter, you’re dealing with mildew.
If it remains dark, you’re most likely dealing with mold (we’ll share some essential tips for DIY mold cleaning later on in the article).
Indoor Mildew Fungus
Ask a gardener about mildew, and you’ll get an accurate description of the fungus:
It’s a common problem on plants and vegetables, but mildew is a type of mold that can grow on any organic material inside your home. Paper, leather, wood, ceilings and floors are just a few of the surfaces that support this fungus.
These are the two most common types of mildew that you’ll find around the house:
1. Powdery Mildew
Identified by its white or gray color, this type of mold first appears as patterned splotches on surfaces, and it becomes yellow, black or brown as it grows.
2. Downy Mildew
Usually found on agricultural products, this mildew shows up in your home as a yellow surface-growing fungus that eventually turns brown.
The 4 Most Common Mold Types
According to CDC estimates, the number of mold species exceeds 10,000 and may be as high as 300,000.
The fuzzy or slimy growth is usually black or green, but its color can appear as shades of white mold, blue, gray, brown and yellow.
There are many warning signs of mold in your home; be sure to familiarize yourself with them.
Airborne mold spores are associated with a wide variety of health issues. Stachybotrys, also called toxic black mold, is especially dangerous, and we’ll cover it in more detail with a future post. Most household molds are one of these 4 types:
This mold is dark brown and has a wooly or down-like texture.
Alternaria is one of the few molds that can also thrive in environments with very little moisture like bedding, upholstery and insulation.
There are more than 30 species of this mold, and 22 are known to cause health problems.
Cladosporium is identified by its powdery appearance and black or olive green color.
You’ll find this mold growing on stale bread or old cheese, but it also takes hold in mattresses, carpets and even wallpaper.
The fuzzy green or blue fungus is used to produce penicillin and commonly produces a strong musty odor.
Of all the mold types, this slimy fungus is the most likely to threaten your family’s health. Toxic black mold gives off a noticeable musty smell and grows rapidly in areas that are constantly damp.
Important DIY Precautions
We outlined the seven steps for DIY mold cleanup projects in this post. If you’re thinking about taking on the job yourself, be sure to follow our recommended precautions.
DIY mold removal can have very negative effects on your health, so always be cautious.
Never attempt to do it yourself if:
- The area that’s affected covers more than 3 square feet.
- The material or surface is difficult to clean.
- You suffer from any type of respiratory problem.
Advantages of Professional Mold Inspection Services
Unlike ordinary mildew with its flat growing patterns, molds attach to materials with microscopic filaments that penetrate beneath surfaces. Its invasive growth quickly spreads through sheetrock and wood causing permanent damage to your home’s structure.
It’s hard to tackle mold with DIY remedies because the fungus grows in areas that you can’t see or access.
The safest way to determine the extent of a mold problem is to call in a company that handles inspections and mold testing here in Chicago, IL or your area.
A mold remediation contractor determines the type of mold in your home, its location throughout the house and the best course of action for addressing its source.
Professional mold removal services are often the safest way to eliminate this potentially dangerous problem.

Mildew is a type of mold. However, not all molds are mildew. Mold grows on and into porous, organic materials. Mildew lives on hard surfaces like bathroom tile. Mildew is powdery and lighter in color than other molds.
Mold is more invasive than mildew. It grows quickly in drywall, wood and carpet making it very difficult to remove. Mildew doesn’t penetrate surfaces, so it’s easier to eliminate.
Mildew exposure can cause the same symptoms as mold exposure. Both microorganisms spread as airborne spores, so both are easily inhaled. Mildew allergy symptoms include congestion, watery eyes and respiratory problems.
