Mold vs Mildew: What’s the difference?

Many people don’t know that there is actually a difference between mold and mildew. A fungi is a fungi right? Well, although that may be typically accurate, there are more then a million species in the mold families. All of which are different sources of organic compounds found in our every day environments.

Mold and mildew are types of fungi; typically, mold is black or green, and mildew is gray or white (but not always). Mold tends to grow on organic surfaces, whereas mildew is an issue on damp surfaces, like bathroom walls, basement walls, or fabrics. Mold grows in the form of multicellular filaments or hyphae, while mildew has flat growth. Mildew is often referred to as a kind of mold that is in one general area and isn’t growing or spreading. Mold can contaminate your indoor environment and spread rapidly though spores in the air.

Appearance & Identification:

Without a proper sample it is hard to determine the species of fungi you are dealing with and is best left to the professionals. Visual inspections of the fungi can vary and be hard to determine without proper examination.
Mildew: could be downy or powdery: Downy mildew starts as yellow spots that first become brighter in appearance and then the color changes to brown. Powdery mildew is whitish in color and that slowly turn yellowish brown and then black. This is why it is important to remember that not all black molds are a toxic black mold. Analysis is needed to determine this, and hiring a professional to take the samples so you don’t disrupt the surface and the spores is best.
Mold: has a fuzzy appearance and can be an orange, green, black, brown, pink or purple in color. Can be found in several shapes. Mold tends to grow and spread through out the damp surfaces and will find other damp or wet areas in the home. Mold can travel through the air and contaminate adjacent areas of your home from moving furniture, furnaces, air conditioners, fans and dehumidifiers. If your home has mold or mildew in it, it is best to get everything sampled before preparing the removal process.


To prevent mildew at home, keep all the areas moisture-free. There are mildew removers available at stores to eliminate mildew. To protect crops from mildew use mildew-resistant seeds, remove infested plants, avoid overhead heating.

To prevent mold in your home, you need to keep all the areas dry and moisture-free. Check the humidity levels inside the house and take measures to control it. Finish perishable food within 3-4 days.

Prolonged exposure to mold spores can cause health problems such as allergic reactions and respiratory problems, due to the toxins (mycotoxins) it produces.

Mildew can cause damage to crops and other plants it infests. Inhalation of mildew can cause coughing, headache, scratchy throat and lung problems. Mildew can also start growing in lungs and cause other serious health problems.

Calgary Indoor Air Quality Testing

Calgary Indoor Air Quality Testing
Managing Partner of Got Mold? Calgary, James Zolkavich, invites all residents of Calgary and surrounding areas to schedule their air quality tests. According to Zolkavich:
Any resident impacted by the summer floods or any type of water damage, should consider an air quality test because the air you breath will have a direct impact on your health. Air quality testing is very important if you have small children who have respiratory issues or suffer from asthma, which is now proven to be caused by bad air and in particular, mold. Poor air quality can also cause sinus issues and allergic reactions. Constant exposure to bad air will also lead to Chronic Inflammatory Response Syndrome, known as Sick Building Syndrome, which the World Health Organization states is directly caused by water damage.
Founder and President of Got Mold?, James C. Watson, based in Saskatoon, also recommends the following:
You should consider an air quality test If you smell an earthy, musty, mildew and even urine like odour. This smell is usually an indicator of Microbial Volatile Organic Compounds. MVOC’S are an indicator of active and past fungal (mold) growth and should not be treated lightly because this will have a negative impact on air quality as well.
