Mold Prevention

Mold Prevention is all about taking steps to reduce the likelihood of mold. Before we discuss mold prevention, let's go over the mold differences between toxic and good mold.

Good Mold and Bad Mold

Good Mold

Not all mold is harmful to humans. Mold is a fungus that develops in the atmosphere when the conditions are right. There are lots of good molds that naturally develop and can be used to our advantage. These molds can actually be good for us! Mold is used in many different industries, two of the most common are the medical industry and the food industry.

If you’ve ever eaten a Mushroom, then you’ve eaten mold! Cheese is another example of mold in food. Blue Cheese is probably the most obvious, but most high-end cheeses get their unique taste from mold. This is done through a carefully monitored aging process in a controlled environment. Everything from temperature, moisture and lighting is taken into account. Please DO NOT grow mold on food yourself and eat it! It’s very dangerous! The food industry has to follow strict laws and guidelines in order to operate and they also have years of experience!

Bad Mold

Bad mold is commonly referred to as “Black Mold” by the general public. There are many different types of bad mold. Not all of them are “black” and just because it’s black in color doesn’t necessarily mean its toxic! Toxic mold can come in many different colors like white, yellow and green.

These toxic molds usually grow on organic building materials such as drywall and wood. Toxic mold can be deadly and professional help is always recommended when dealing mold. Mold Men of Pittsburgh uses state-of-the-art products to remediate toxic mold and touch it without containment suits and respirators.

Measuring Mold

Mold is measured by the number of spores that are present in a particular area.  This measurement is called parts per million, or (PPM). Mold Men of Pittsburgh offers detailed testing to measure the PPM. This gives us the information we need to properly diagnose (type of mold and its toxicity) and remove the mold.

Indoor Mold

There’s a difference between outdoor mold and indoor mold. Generally, mold should not be present indoors in high concentrations. Low levels of indoor, non-toxic mold can be natural and should not cause a problem. High levels of toxic mold spores can be an indicator that indoor atmospheric conditions are out of balance.

There are certain types of mold found indoors. These toxic molds thrive in dark and wet conditions with little to no air flow and are generally referred to as “wet molds.” Wet molds are problematic and unhealthy. Some of these wet molds can be highly toxic and dangerous at even low levels. Stachybotrus and Chaetomium are two examples of toxic wet molds. Other types of mold produce what’s called micro-toxins. These micro-toxins can be a problem for the structure of a building and to humans.

A Wet Feeding Source

  • Mold needs a water source in order to feed.
  • Mold needs a feeding source like drywall, wallboard, ceiling tile, unfinished wood, the backing material on carpets, or any product with a high consistency of paper.
  • Mold thrives in dark stagnant places with high levels of moisture.
  • Mold grows in concealed and confined places with high levels of moisture and low light conditions.
  • Building materials in these areas are a breeding ground for mold.
  • Some of the best places for mold to grow are behind walls, in attics and in basements.


Mold spores grow, feed and spread at a more rapid rate when the temperature is between 65°F and 100°F. The problem is that this range is normal for most indoor environments.

Indoor environments can be impacted by:

  • Inadequate ventilation and air flow
  • Poor insulation and not allowing a building to breathe
  • Low light or no light
  • Warm temperatures

When you couple all of these things together you get the perfect conditions for mold. If you want to take mold prevention steps now, ensure you have a dry space! Keeping certain areas in your home dry will prevent the mold from ever growing and save you money in the long run.
