Remove and Replace Your Moldy Carpet

Updated April 1, 2024 . AmFam Team

Excess moisture can cause many issues in your home, mold included. And where your carpet is concerned, mold can be evasive — hiding in the fibers and sending spores into the air you breathe without you noticing. Not to worry, as there are many ways to stop mold in its tracks and prevent it from coming back.

How to Get Mold Out of Carpet

If you want to try getting rid of the mold yourself before calling in a professional, you’ll need to follow a few essential steps.

Gear up for mold removal

Goggles, a respirator and rubber gloves are the bare minimum equipment, since mold spores can cause moderate to severe irritation to your eyes and lungs. You’ll also want to wear clothes you don’t mind being ruined, especially if the mold is particularly widespread.

Remove moisture

Whether it’s a leak, flooding or a spill, removing the source of the moisture that’s feeding the mold growth needs to happen before you can clean up the mold itself. You can use materials like cat litter, talc-free baby powder and baking soda to soak up any liquid. Leave it on the spot overnight, the vacuum it up in the morning.

In some cases, this may be enough to stop mold in its tracks. Removing the source of moisture and drying the area out can cause many small mold colonies to die off. But if there is standing water, you may need a wet-dry vacuum to remove it and consider these tips to keep your home free of water damage.

Be thorough

Peel up a piece of the carpet where you suspect the mold is growing. If the mold has gone all the way through to the backing, it may be too far gone to do this yourself. If not, you can start soaking the section.

How to Stop Mold Growth: What Kills Mold on Carpet

There are a few different solutions you can use to kill off mold colonies. You’ll first need to perform a base cleaning, which is best done with a rented carpet cleaner. You can also hire a professional carpet cleaning service to get that job done. After the base clean is dry, consider one of the following steps:

White vinegar

A common home remedy is to use white vinegar, which you can apply directly to common household without diluting it.

Bleach

You can also use bleach diluted in water, but only use this method if you don’t mind your carpet being bleached out. It may also damage the fibers of your carpet, causing bald spots where you’ve cleaned.

How to kill carpet mold with vinegar or bleach

  • Spray an even layer of cleaning solution over the moldy spot, then let it sit for at least an hour
  • After that, give it a good scrub while wearing your respirator
  • You can let this dry overnight; blow dry it or — if the carpet is easily removable — you can hang it outside in direct sunlight
  • Sunlight can kill mold outright, but it’s best to combine that method with a cleaner to remove the mold with certainty

Using antifungal sprays

There are industrial antifungal sprays you can use, but they can be potent and damaging to the carpet. If you think you need something that strong, you probably need to call a professional.

HEPA vacuums

Vacuuming up the area after it’s dry is important, but your regular vacuum might not cut it. Experts suggest renting a HEPA vacuum to suck up any remaining spores and prevent them from dispersing into the air.

What If There’s a Lot of Mold?

A room full of mold is not a task for one person. But even a 10-square-foot patch of mold is something you should call a professional to handle. If the mold has spread past the carpet and into the padding, insulation or floorboards, it’s also time to get some help.

Mold remediation professionals are usually educated in the different types of mold and how to get rid of them, so make sure to choose someone with a lot of experience. You’ll also have to remove the carpet entirely and replace it with new, clean carpet after the mold is destroyed.

This could be true even if there isn’t a ton of mold — if you have extensive water damage, warped floorboards beneath your carpet can cause structural trouble and need to be dealt with by removing the carpet.

Mold Prevention Tips

Once you’ve removed the mold in your home, you’ll want to keep the humidity level low in your home, around or below 50 percent. There are many options to consider that can help maintain low humidity in your home such as installing a dehumidifier or running your bathroom fan when you use the shower. And if you live in a swampy or tropical environment, consider leaving your windows closed to keep the moisture out. With so many ways to maintain a decent humidity in your home you’ll be able to find out what works best for your house.

Does Homeowners Insurance Cover Mold Remediation?

Mold growth caused by lack of proper maintenance or an aging home is generally not covered by homeowners insurance. You should be aware that issues caused by improper home maintenance aren’t usually covered, either. So be sure to review your homeowners policy if you think you might be covered for a mold-related event.

Keeping mold out of your carpets is an active process that involves vigilance and regular home maintenance. Now that you have the tools and know-how to stop mold growth in its tracks, you can continue protecting your home and everything in it.

If you’re unsure whether or not a covered event that caused water damage will also cover mold removal, speak with your American Family Insurance agent.
