Do You Have White Mold In Your Crawl Space?

Identifying White Mold

White mold is a variant of fungi species. Its name is derived from its appearance as a white substance that can take on two different textures. White mold can either appear to be fuzzy in texture or light and powdery. The growth and spread of this fungus occur because of high moisture levels and low airflow.

This fungus is most often found in crawl spaces, which come into direct contact with the soil, rocks, and water beneath your home. The moisture that results from heavy rainfall, plumbing leaks, and poor dehumidification in conjunction with the low airflow of crawl spaces, serve as perfect breeding grounds for white mold.

White Mold vs Efflorescence: Understanding the Differences

Many people often confuse white mold with efflorescence. White mold is harder to eliminate than efflorescence and has much more serious implications. The difference between white mold and efflorescence is that the latter varies between white, brown, and yellow colors. Even if both substances look the same, unlike white mold, efflorescence has no odor and dissolves in water. However, if left untreated, it is common for efflorescence to develop into white mold–especially if it accumulates in areas like crawl spaces that serve as perfect breeding grounds.

Common Locations of White Mold in Crawl Spaces

White mold can be found in one of two places in your crawl space. The first and most common place you can find white mold is where the structure meets the soil. As rainfall and water gather in the soil and make it damp, mold can grow as humidity ensues after the rainfall.

Exposed soil is known to encourage the growth of white mold. Often, this is due to an incomplete or missing vapor barrier. The soil’s limited airflow and excess moisture increase humidity and allow for mold growth. White mold can also form on the floor joists of your crawl space under certain conditions.

Early Signs of White Mold in Crawl Spaces and Health Implications

Dampness and increased humidity levels in and around your crawl space indicate that white mold has begun to grow and spread there. Musty odors often spread in conjunction with the growth of white mold. This odor can cause mild to severe allergic reactions, including watery eyes, itchy skin, sneezing, coughing, shortness of breath, dizziness, headaches, runny nose, and in severe cases— asthma.

Another indicator of the presence of white mold in your crawl space includes climate changes around your home. White mold grows and spreads fast under the right circumstances. It is common for it to reach different parts of your home that are located near your crawl space. If you are experiencing any of the symptoms that come with exposure to this fungus, chances are it’s already growing in your household.

Inspect your crawl space for white mold and keep in mind the signs that may indicate its growth. These steps will help you to prevent it from spreading. It is especially important to detect the growth of white mold in its initial stages before it spreads. Doing so can prevent further damage to the structural integrity of your home as well as your physical health.

Techniques for Detecting White Mold in Your Home

Aside from visual inspection, the easiest way to detect white mold is through direct mold sampling. There are many different approaches to this practice, including tape lifts and swab/bulk samples. These are common methods that your local mold technician may perform, after which they will send samples to a laboratory for analysis.

When to Seek Professional Mold Remediation Services

White mold is known to cause mild to severe allergic reactions and health problems that can be as serious as an asthma diagnosis. It is best to seek the expertise of a specialist near you if you suspect that your crawl space has accumulated any white mold, or if you are experiencing symptoms. Not only can you nip these problems in the bud, but you can reap the benefits of crawl space repair and encapsulation.
