Your carpet provides the perfect environment for mold to grow, as it contains organic fibers that can hold on to water for an extended period of time. Mold and mildew growth can be a serious health concern and can aggravate respiratory conditions that you may have, such as asthma. However, it can be hard to initially determine if your carpet has begun to grow mold, which means that you should know what signs to look for to determine when you should call a carpet cleaning specialist for your carpeting.

Odd Smells

Mold will usually give off an earthy or musty smell, so if you notice any strange smells in carpeted rooms, you may want to inspect your carpet for signs of mold growth. If the smell gets worse the closer you get to the carpet, even if you can't see any physical mold growing on the fibers, you should likely look into have your carpet professionally cleaned or replaced.


In a similar vein to the above point, if you notice that your allergies or other respiratory conditions have suddenly gotten worse, especially if it is the off season, you may have mold in the carpeting of your home. See if your conditions get worse after staying in rooms that have carpeted floors for a short period of time when compared to staying in rooms without carpeting. If this is the case, you should contact a mold remediation specialist as soon as you can.


This is easier to spot for light colored carpets, but any sort of strange discoloration, especially black or dark green, can indicate mold and mildew growth. If you notice a musty smell, as described in the point above, you should visually inspect your carpet for any signs of organic growth on your carpet.

Damp Spots

A clear indication that you may have mold growth occurring within your carpet (or at least are at high risk of mold growing in the future) is if you notice damp spots on your carpet. While damp spots can be caused by a number of different factors, from leaking pipes near your carpets to simple spills of drinks and liquids, they can provide the perfect conditions for mold to begin to grow. If you notice damp spots on your carpet, you should inspect your carpet for signs of mold growth, and then dry out the area using fans or a dehumidifier. Additionally, you should look in the surrounding area for the source of the moisture in order to fix it and proactively prevent future mold growth.
