Signs Of Mold Growth On Your Carpet

The mold starts germinating on a wet carpet after around 2 days, the spores will spread between 3 to 12 days, and you will notice visible signs after about three weeks. You have to be alert for signs of mold growth in problem areas like the basement, kitchen, or bathroom. You can usually detect mold presence before it becomes too severe.



The smell is a typical characteristic of this fungus. If you notice a musty or damp odor, then chances are there’s mold nearby.



The mold appearance is evident after 21 days, but sometimes you can catch it early. Pink, brown, orange, purple, and black spots mean there’s a mold colony nearby.


Why Does Mold Grow On Carpets?

Your home carpet is usually the recipient of leaks from pipes or appliances. This floor piece has tight fibers where moisture can get stuck.

Mold thrives in moisture, so a damp carpet is a perfect place for spores to grow. Rugs are also difficult to dry when they’re left indoors, so the fungi can multiply.

Homeowners usually take their carpets for granted; they may even forget they have one lying around in the basement. Not addressing the mold can lead to significant problems in the long run.


Risk Factors Of Mold At Home

Mold looks unpleasant, but besides that, it can cause health problems for your loved ones. Some mold types may not pose a threat, but others, especially black mold, are dangerous. Their spores have mycotoxins which can cause severe respiratory problems to members of the house.

People can also develop allergy and asthma symptoms when they inhale mold spores. These conditions might also be underlying symptoms of a more severe mold illness.

The smell also gives an unpleasant aroma to your home. It can turn away guests and even the family who live there.

Constantly monitor the high-risk areas, especially your basement. Once you spot any water damage, you should clean it up before mold forms. Here are tips for how to clean a water damaged carpet.


Step-By-Step Process On Removing Mold From A Carpet

Once you’ve discovered the mold source, you need to clean it up. Usually, porous materials like drywall and gypsum are hard to clean, so it’s better to throw these out if they get contaminated by mold.

Carpets damaged by flood water are also unsalvageable, and they should be thrown out. You should do this because the sewage water brought by floods has too many contaminants. Always wear the proper safety gear when you’re cleaning mold to keep yourself safe.


Step #1. Ventilate the area

Make sure the windows in the room are open but keep the doors closed so the spores don’t reach the other parts of the house. You can use an electric fan to keep the wind flowing freely. You must do this to prevent the spores from settling on other surfaces.


Step #2. Brush off the visible mold

Rub a stiff brush over your carpet so the mold will come off. Put the pieces in a bag, then discard them. You can also use a HEPA vacuum to help clean up the debris.


Step #3. Scrub the area with cleaners

Now you can give your carpet a deep clean to kill all the remaining spores. You can buy cleaning agents or make a D.I.Y. version using the materials you have at home.

You can use dish soap, baking soda, vinegar, or essential oils. Just avoid bleach as this can damage your carpet. Check out this guide for moldy carpet cleaning agents.


Step #4. Let everything dry

Now that the spores are gone, you need to let your carpet dry thoroughly. You could leave it outside under the sun or use electric fans to let it dry faster.


How To Prevent Mold On Carpets

Now you’ve cleaned off the mold, how do you prevent it from growing back?


1. Keep the carpet clean

Mold thrives in humid and dirty environments, so you must keep your carpet in good condition. Try vacuuming it weekly to remove dust and dirt.


2. Monitor the humidity

Try placing a dehumidifier in your problem areas. Keep the humidity below 65% for healthy surroundings.


3. Avoid high temperatures

Mold also loves high-temperature areas, so try to keep your basement, kitchen, and bathroom cool. Portable air conditioners are an excellent investment because it keeps the air cool and dry.


4. Use synthetic carpet materials

That wool carpet may be tempting, but these organic materials are more sensitive to mold growth. Try choosing an olefin or nylon carpet to save yourself from mold problems.



Keeping safe from mold is essential; that’s why you should monitor its growth around the house. You can keep the home safe when you answer, “how long does it take for mold to grow in wet carpet.” You can be more cautious about water damage and take care of your home’s problem areas.
