Why does mold grow on carpet?

In order to propagate, molds release tiny particles called spores. Spores of mold can be found almost anywhere, including within your home. Mold spores need moisture in order to germinate and thrive, so it’s not surprising to discover it in dark, damp places like a damp basement or a poorly ventilated bathroom. Carpets are ideal for harboring mold because they retain moisture so well.

The dense fibers and small nooks and crannies that make up the weave of a carpet hold moisture once it becomes wet (from a ceiling leak, a basement flood, a plumbing problem, high humidity, or simply because you cleaned the carpet but did not dry it completely). The carpet’s weave is often fastened to a backing. When the backing becomes wet or when moisture penetrates the backing, it can cause the carpet to become trapped beneath water. A wet carpet will remain wet unless it is actively worked to dry using fans, a hot air drier, or a dehumidifier. The growth of mold in a damp carpet will not take long.

It’s not uncommon for us to neglect the carpeting in some areas of our homes. There could be carpet hidden away in a closet or behind a piece of permanent furniture. If the carpet in one of these areas gets wet, it could be some time before you discover the problem, allowing mold to spread.

Why is carpet mold a serious problem?

One’s home’s air quality might be drastically diminished by mold growth. Those who are allergic to mold may experience health issues if they breathe in mold spores. According to the CDC, exposure to mold and mold spores can cause upper respiratory symptoms, exacerbated asthma symptoms, and eye discomfort in persons who are sensitive to mold. According to the results of a meta-analysis conducted by the World Health Organization (WHO), mold exposure is associated with respiratory symptoms and worsened asthma symptoms. For those who are sensitive to mold, breathing in mold spores can cause anaphylaxis. Carpet mold is especially dangerous because it can spread quickly through a room and is typically found in areas where children play.

Damage to buildings and other structures can also result from mold. You may notice a musty, mildewy stench throughout your home if mold is present. The surfaces they grow on are also harmed by mold’s presence. It’s possible that mold growing under a carpet could cause structural damage to the floor or baseboards.

What should I consider before I attempt to get mold out of my carpet?

These items are recommended for removal, disposal, and replacement in every mold remediation manual and resource.

“Moldy wall-to-wall carpet might be hard to clean well,” householders are warned by the California Department of Public Health. In the event that the carpet, backing, or padding is moldy or smells musty, it should be thrown away. You should only keep damp throw rugs if you can wash them properly and they don’t develop a musty odor after drying. If sewage or other polluted water was involved in the flooding that led to the mold, the carpet should be thrown out and replaced.

If you need to remove mold from your home or business, be sure you have the right protective gear. Cleaning up mold will release mold spores into the air and may require chemical cleansers with fumes, therefore it is important to use protective gear such gloves, goggles, and a respirator mask.
