Are You at Risk for Mold?

Mold. It can take over your property without you even knowing it. The key is to make sure you keep your unit or property maintained in a way that prohibits the growth of mold.

Molds need just 3 things to grow:

  1. Food: Mold "food" is considered anything that used to be alive; wood, cardboard, wool, silk, leather, etc.
  2. Temperate climate: The ideal range of temperature for mold growth is 68-86 degrees Fairenheit, the same range we typically like to keep our homes in.
  3. Water: A humidity factor of only about 60% or higher is likely to spur mold growth.

Since our homes normally contain a lot of potential mold "food," and are normally kept at temperatures which are conducive to mold growth, all that is missing is water.

Water is the most likely cause of damage to property across the nation.  It includes everything from: overflowing sinks, leaky or broken pipes/hoses, drain or sewer backups, or water from heavy rains or river/coastal flooding.  If water is in contact with any form of dirt the growth can occur even more quickly since dirt always includes organic materials (i.e. "mold food"). 

In any case, water damage must be remedied quickly and thoroughly or it will result in mold growth.  Completely drying the surface is very important since any excess moisture could spur mold.

Mold is often seen as obvious "growth" or even "discoloration" on materials like paper or wood.  Colors can range from white to orange and from green to brown and black, and it gives off the well-known "musty/moldy" smell.

According to the Center for Disease Control (CDC), "the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, coughing and wheezing in otherwise healthy people.  The IOM also found limited or suggestive evidence linking indoor mold exposure and respiratory illness in otherwise healthy children."

The CDC recommends that all molds found in the indoor environment be eliminated, adding, "Generally, it is not necessary to identify the species of mold growing in a residence, and the CDC does not recommend routine sampling for molds."  Since all molds have the potential to cause allergic or allergic-like symptoms in people, especially highly susceptible individuals, they should be eliminated whenever found.

There is no practical way to eliminate all of the mold spores in an indoor environment.  But there are many ways to help control moisture and mold growth in your home or property.

Mold Prevention Tips


  • Fix leaks in pipes and any damp area around tubs and sinks so mold spores don't have a growing environment.
  • If you rebuild or remodel, do so with water-resistant building materials, such as tile, stone, deep-sealed concrete, waterproof wallboard, water-resistant glues etc.
  • Prevent seepage of water from the outdoors into your house.  It's important to have rainwater from gutters or the roof drain away from the house.  The ground around the house needs to slope away to keep the basement and crawl space dry.
  • Ventilate any crawl space as much as possible to allow for thorough drying.


  • Reduce the moisture in the air with dehumidifiers, fans and open windows or air conditioners, especially in hot weather.  Do not use fans if mold may already exist; a fan will spread the mold spores.
  • Try to keep the humidity in your home below 40 percent.
  • In moisture-prone areas, consider easy-to-clean water-resistant floor coverings, such as vinyl or stone tile.
  • Reduce potential for condensation on cold surfaces by insulating.


  • If you discover mold, the first step is to find and eliminate the water source, as above.
  • Then, if it is a small area (less than about 10 square feet), and you feel comfortable, clean the mold with a detergent solution and thoroughly dry all materials.
  • If it is larger than 10 square feet, consider calling a professional mold remediation company.
