If you’ve experienced a flood or a spill, you may be wondering how long it will take for mold to grow in your carpeting.

Typically, mold growth in carpets begins 24 to 48 hours after they get wet. You should seek to dry your carpet in that time or call in the professionals to do it for you.

Already have mold on your carpet? Here are a few types of mold that might have started growing on your wet carpet and what you can do to prevent the problem next time.

Kinds of Mold that Grow Wet Carpets


There are many types of mold spores in your home, waiting to get the right conditions to grow. While several of these types could grow in your carpet, some favor the requirements of wet carpeting in particular. Plus, a number of those molds are more harmful than others, capable of provoking allergic responses or irritating your lungs and eyes. Here are some o the carpet molds you should know:

  • Alternaria: Alternaria is also an allergenic mold that could bother your lungs. It spreads particularly quickly and must be removed quickly to prevent spread.
  • Chaetomium: This mold is allergenic, and certain breeds of it can also lead to skin and nail infections. It usually generates a odor when growing in your home.
  • Tichoderma: Tichoderma prefers to grow in wet carpets and other fabric surfaces. Some strains of it are non-toxic and just unsightly. Others are more dangerous and create toxins. As tichoderma is resistant to antifungal and heat remedies, any carpeting it’s growing on has to be removed.
  • Fusarium: This is just another toxigenic mold that will prefer carpets. It’s also conducive to cold conditions, so you may find it in your basement or growing in your home during winter.
  • Stachybotrys: Stachybotrys is the so-called “black mold.” While the mold is rare, it’s dangerous and creates toxins. While infants have died from exposure to large quantities of the mold, cases of”sick building syndrome” from this mold are somewhat controversial.


Trying to spot your mold by color and texture often doesn’t function, as most molds have dozens of variants. Just a mold professional can identify the type of mold you’ve got and tell you just how to remediate it best.
