A moldy carpet can make your home smell bad and even cause health problems. If you think your carpet might have mold growing in it, there are a few things you can do to find out for sure. If you do find mold, try to clean or replace your carpet as quickly as possible before it spreads. Carpets can provide the ideal environment for mold to grow in. If your carpets get damp and stay damp for longer periods, mold can set in. The problem here, though, is that it’s usually in the underlying layers. You may not even see it.

Mold grows abundantly in areas where humidity is high. Plumbing leaks that deposit small amounts of water on or under carpet provide a fertile growing medium for mold and mildew. Mold and mildew are unsightly but even more importantly are dangerous to your health. The spores can become airborne which makes them easy to breathe; they can cause allergic reactions or even trigger asthma attacks. Other molds simply settle on surfaces and grow in colonies. Determining whether there is mold in the carpet is fairly easy.

How to detect mold in the carpet?

Carpet has many amazing qualities – it\’s soft, keeps the floor warm, makes your home look great, and filters the majority of allergens out of the air. Unfortunately, it is also prone to growing mold.

But how do you know when your carpet actually has mold?

Mold can grow quickly in damp places, and once it gains a foothold in your home, you have to put in a lot of work to remove it. It can sometimes be hard to tell whether you have mold because it often grows underneath the carpet. Regular inspection is the only way to rule out carpet mold. Five signs that indicate the presence of carpet mold are listed below.

1. Musty odor: A musty odor is one of the top signs of mold. If you spend most of your time at home, then you may not notice this odor. However, anyone who visits your home will likely smell it. If anyone comments on the odor, then this is something that you will need to take note of.
2. Unexplained allergies: Carpet mold has been shown to cause breathing problems, allergies, bronchitis, and asthma. If you or anyone in your household has those issues, then you will need to inspect your carpet for mold. However, not everyone who is exposed to mold will have a problem.
3. Damp carpet: Any carpet that remains wet for more than a day is likely to grow mold. If you notice that your carpet is frequently damp, then the source of the leak may be under the carpet. Basements are where mold is most commonly found, but even accidentally spilling a drink on the carpet can lead to mold. Either way, you will need to dry the water up as soon as possible.
4. Positive results from a mold testing kit: One of the most reliable methods of confirming the presence of mold growth in your carpets is by using a mold-testing kit. These kits work by testing the airflow across the carpet. If there are any mold spores in your carpet, then they will land on the testing kit and multiply to give you clear results.

How to get mold out of the carpet?

If you have mold in your house, it is vital to remove it as soon as possible. Mold spores may cause serious health problems. On hard surfaces like metal or concrete, scrubbing it with a cleaning solution will get rid of the mold.

But if mold shows up on your carpet or rug, removing the mold will not be as easy.

Why does mold grow on carpets?

Mold is a fungus that spreads by releasing spores. Mold spores are everywhere, including in your house. To grow and develop into the mold, the spores need moisture, which is why you often find mold in damp places like a wet basement or a poorly ventilated bathroom. Mold grows well on carpets because they are great at trapping moisture.

Once a carpet gets wet (because of a ceiling leak, a basement flood, a plumbing problem, high humidity, or simply because you cleaned the carpet but did not dry it completely), moisture gets trapped in the dense fibers and tiny nooks and crannies that make up the weave of the carpet.

Most carpets also have a backing that the weave is attached to. If the backing gets wet, or if moisture gets under the backing, the backing can trap the moisture under the carpet. Unless you actively work to dry a wet carpet using fans, a hot air drier, or a dehumidifier, a wet carpet will stay wet. And it will not take long for a wet carpet to form mold.

How to get mold out of the carpet?

1. Ventilate and isolate the area properly. The goal is to prevent mold spores from spreading throughout other parts of the house, but still, keep the area well-ventilated. Close doors or use plastic sheeting to block off some areas, and use fans to blow air out an open window or door that leads outside. It is more important to keep the area well-ventilated than it is to isolate the area, especially when using cleaning chemicals.
2. Use a stiff brush to remove as much visible mold as possible. Sweep the mold into a bag and discard it. You can use a vacuum with a HEPA filter for this, but there is a chance that mold spores will reside in or on the vacuum and spread to the rest of your house the next time you use the vacuum. A non-HEPA vacuum might not properly contain mold spores.
3. Scrub the affected area thoroughly with cleaner. Bleach is not necessary or recommended. Some types of mold produce chemical compounds known as mycotoxins. Removing the mold and mold spores will help remove this concern as well.
4. Allow the carpet to dry completely.
5. Use a HEPA vacuum on the carpet again to remove as many spores as possible.

Once mold gets into the carpet, it may be difficult to remove. If replacing the carpet is not an option, a thorough cleaning that prevents mold from spreading elsewhere in your house could solve the problem.

Keep your carpets dry, and dry them out quickly if they get wet, to prevent mold from forming in the first place.
