4 Signs That You Need Mold Remediation

4 Signs That You Need Mold Remediation

The general rule is that when mold is visible, it is time to kill it and remove it. But mold isn’t always visible and so there are other criteria to strongly consider when it comes to mold remediation. Here are the four criteria to look for mold in your home.

1. A water event or occasional/frequent water intrusion

Has there been recent water intrusion? Water does not necessarily equal mold growth as spores have to already be present. But since mold spores are microscopic (2-10 microns), a water event is usually the trigger that causes mold to be seen or otherwise detected.

Note: Mold means moisture or humidity is, or has been present. Water does not necessarily mean mold growth is present.

2. Discoloration

Most molds cause the organic material the mold is consuming to change colors. Whether the food source for the mold is human food or drywall paper, if colonization is allowed for enough time, there will usually be a discoloration that will reveal a mold problem.

Most molds, when allowed to grow in abundance, are visibly seen in certain colors. Mold is not only black. Many species are visible in gray, white, brown, red and even some hues of pastel colors. Some molds look like dust, or fuzz, while others look like sand granules. Certain molds thrive on certain food sources, and they all require different moisture content or relative humidity in the ambient air.

Note: Water seeping through masonry sometimes causes a white crystalline, powder-like discoloration called “efflorescence”. This substance is made up of minerals and should not be confused with mold.

3. A musty odor

Is there a musty odor that prevails, or come and goes? Some molds are odorous when colonizing. Although some species do not cause odors, when a musty, moldy odor is combined with other criteria, one can conclude that mold is present. Even if mold is not visible, remediation may be necessary.

Note: Some individuals have a great sense of smell. Others may think that they do. Odor alone should not be the only criterion used to determine whether remediation is necessary. Some actively colonizing fungal species give off odors. Dead or dormant spores generally do not, but are just as detrimental to human health. Absence of odor does not mean that there is no mold and odor does not mean that it is caused from fungal growth. Do not rely solely on scent for detection.

4. Adverse human health effects

A good indication that there is “unacceptable fungal ecology” within a building envelope is that occupants feel health symptoms when spending extended periods of time in a certain space and feel much better when spending extended periods of time outside that space. If residents in a home or employees in a workplace experience congestion, allergy symptoms, headaches, fatigue or respiratory problems after each night’s sleep or after the end of each work day, this may be an indication of unhealthy air quality.

One environmental hazard to cause unhealthy air quality is a mold infestation. If one spends a week on vacation away from work and home and all symptoms disappear, perhaps the home, school or workplace has unacceptable fungal ecology or unhealthy indoor air quality

Mold exposure can lead to several health-related problems. With its natural ability to travel through the air, the inhalation of mold spores can create a variety of respiratory ailments. Common side effects include asthma, allergies, respiratory infections, sinus infections and skin rashes. In some cases, mold exposure can even be fatal.
