Mold & Fungal Growth

Crawl Space Mold & Fungal Growth

Mold is everywhere. There is no need or ability to get rid of all mold in the world. Mold is a fungi that exists naturally. There are numerous different types and species and the kind of mold will determine the impact on your home and/or health. In order for mold to grow, it needs moisture, a nutrient or food source and a warm environment. Moisture is the main element required for mold growth. This can be in the form of water or just high humidity. Nutrients for mold are mainly materials made from plants, which include many building supplies. Food sources for mold can come from almost anywhere including wood products, dust and dirt. Mold generally grows above 32 degrees Fahrenheit and will grow faster as temperature rises to about 80 degrees Fahrenheit. In higher temperatures, the mold will continue to grow, but the rate of growth may slow. Without these factors, mold can remain present but dormant for many years. However, as soon as moisture is reintroduced the mold will begin to grow again.


Mold is not a new problem but there has been a heightened awareness to mold over the last decade. There have been changes to home design and building over the last few decades as homes have become more energy efficient and tighter. While that is great for reducing energy usage, it has created problems in indoor air quality. Indoor air pollutants including mold can no longer escape to the outside.

  • Mold may or may not be a health issue.
  • Mold should be removed from inside your home, attic, or crawlspace when found.
  • Mold should be seen as an indication of a problem - generally with water or moisture.
  • All molds are not the same. Some molds are called indicator species and require more available water to grow than other molds.
  • Some of these indicator species of molds are also more likely to be associated with health issues, particularly Aspergillus and Stachybotrys are often talked about.


How much is too much? There are no set standards for "acceptable mold levels." From a health standpoint, it will vary from person to person. Some people are highly allergic to even slight amounts of mold and others are not affected.  The exact correlation between adverse health effects and mold still needs more scientific study. It has been difficult to make a direct link between mold and a specific health claim.


Keep in mind again that mold is everywhere and cannot be eliminated completely. However, mold inside a home or crawlspace should ideally be similar in type and quantity to mold found naturally outside the home. Mold that is present will generally need to be remediated and then prevented.  If you have a real mold problem and/or you or someone in your home is highly sensitive to mold, contact a professional mold remediation company to determine the best course of action. Check references and licenses for mold expertise. If you attempt to remove small amounts of mold on your own, you need to take precautions to protect yourself and avoid spreading mold spores to other areas of the home. When investigating options for mold remediation, keep in mind that bringing in new chemicals can create new health problems from using hazardous substances. Remember that your home will never be mold-free.  Even after an expensive mold remediation, without eliminating further moisture in a crawlspace, the problem may still exist and mold could grow back again quickly.  A moisture control system can stabilize the moisture levels, but it cannot remove mold that is already present.
