carpet mold

Mold growth in any space either in a commercial or residential space can be a major problem for anyone. Once it is spotted, it can be removed in an effective and easy manner. The major problem with mold growth is its ability to spread unnoticed all through your building. This can cause widespread damage and lead to health issues for residents of the building, it may even take weeks to months before the mold becomes noticeable. Let’s take a quick look at the likely causes that leads to mold growth beneath carpets.


The Carpet and Rug Institute (www.carpet-rug.org) stated that anything can turn to mold as long as there is a food source and adequate moisture that enhances its growth.

In the home, carpets, area rugs and wall to wall carpeting are the major areas that have the highest risk for growth of mold spores. For molds to grow it needs oxygen, moisture vapor, a surface that it would grow on and a food source. Mold spores occur naturally in the air, so when they land on a damp spot in the building which has dust for them to feed on, it subsequently leads to growth of molds.

When you notice mildew and mold beneath your carpet, this shows that there is an increased amount of moisture under the carpet. One of most common cause(s) of this in prevailing structures is vapor or moisture seeping into the concrete subfloor from the subsoil outside.

This occurs when there is fluctuation in the water table when the vapor barrier in the structure is compromised or the building does not have a vapor barrier in place in the first instance.

On the other hand, the problem of increased amount of moisture in the building can be caused by installing sprinklers a little too close to the building, the implication of this is that water infiltrates the building’s foundation and subsequently seeps into the concrete subfloor.

In summary, when moisture seeps into the concrete subfloor, it would rise up through the concrete and the moisture gets stuck beneath the carpets which have backings that are impermeable.

The vapor does not have any avenue to evaporate and escape, and when there is a change in temperature, the moisture condenses into liquids giving the needed moisture that leads to the growth of mold spores.

Just because you cannot see the molds or they aren’t visible on the carpets surface doesn’t imply that molds are not in action. The amazing part of mold growth is that it only becomes prominent on the surface of the carpet when it is already in its advanced stages.

So when you notice a discoloration or odor in your carpets, or the carpet is wet or water damaged from standing water, seeps from the concrete subfloor or flooding, be careful as these are the conditions that are most suitable for mold and mildew growth.

One tip to avoid a lot of moisture on your carpet is to hire a local carpet cleaning service that doesn’t use gallons of water in their process. This means you should avoid steam cleaning and carpet shampooers.

Instead, choose Arevalo Bros Chem-Dry in Chicago. We use 80% less water than steam cleaning and extract almost all of the moisture we use for cleaning carpet. This leads to drier carpet and eliminates the chance for mold growth.
