5 Signs of Mold Under Hardwood Floors

Floorboards that are discolored, distorted, or twisted are a clear sign that you have a mold issue. On hardwood flooring, mold frequently manifests as discoloration, staining, or a fuzzy-colored growth. Most often, a minor water incident in the house is followed by a mold infestation.

There are some critical signs of mold under hardwood floors. These include musty smell, color, and texture. If you notice any of these signs, you should contact a professional. In addition, you should have your floor professionally inspected to be sure. Fortunately, there are several easy ways to detect mold beneath your hardwood floors. Read on for helpful tips! Below are five of the most common signs of mold under hardwood floors.


Mold grows under wood floors and loves the lack of air circulation. You need to inspect the wood immediately if you find a spot with a moldy smell. If you can see the wood, you can test it with a flat screwdriver. If the wood is soft, there is a good chance of a mold problem under the floor. If you can’t identify the odor, contact a professional.

If you think there may be mold under your wood floors, there are many ways to treat it. First, you must measure the moisture content quantitatively to eliminate the mold. One way to do this is to purchase a hardwood floor moisture meter. These meters give you fast readings in %MC. You can then decide whether or not you need to have your floor replaced. However, if you do decide to repair yourself, you should take care to protect your wood floors.

To test for mold, you should use household bleach. Borax has antimicrobial properties and kills the spores of mold. Mix a tablespoon of borax with a cup of water. Apply the solution to the affected area using a damp cloth or sponge. If you see any raised or uneven texture on your wood, there is a high chance that you have a mold problem. A deep-seated mold may have penetrated the wood if you notice the raised texture. In this case, you’ll need a professional to remove the mold, and cutting and replacing the wood may not be possible.

Mold grows on wood that is repeatedly exposed to moisture. While mold does not cause illness, it can harm your health. People with allergies or sensitivities should always stay away from homes with mold growth. So, check your floors for signs of mold under hardwood floors today. And, if you notice any of these symptoms, call a professional immediately. You will be glad that you did!

Musty smell

There are several solutions to a musty smell under hardwood floors. The first option is to install an air purifier, which removes particles and spores that cause a musty smell. Unfortunately, it can take several days for the smell to disappear completely. If you’d rather not tear up your floorboards, an air purifier might not be the best option. In this case, you may have to replace them.

You can also try installing a dehumidifier to make your home less humid and inhospitable for mold growth. This method can be particularly effective when dealing with mold under floorboards. It’s also possible to use a bleach-and-water solution, which you can spray on the mold or scrub with a scrubbing brush. However, if you’re unsure of the exact cause of your musty smell, you can try a combination of these methods.

A mold-related smell under hardwood floors is another common cause of the problem. This mold produces volatile organic compounds (VOCs) that harm humans. They can cause serious health problems, including headaches, dizziness, and respiratory issues. People with weak immune systems and those with asthma are more susceptible. It would help to keep your floorboards clean to avoid the musty smell. However, you should be aware that cleaning the floors is only the first step.

A musty smell can signify more significant problems, and ignoring it could result in a lawsuit. If you’ve been experiencing the problem for some time, you should contact a mold remediation professional to help eliminate it. Sometimes, it is possible to clean the wood flooring without damaging it. A cleaning solution that includes the correct elements will destroy the bacteria responsible for the musty odor and prevent the buildup of spores.


You may be concerned about the mold’s musty smell and dark appearance if you have hardwood floors. While hardwood floors don’t provide the perfect breeding ground for mold, they can still grow there if conditions are right. Molds typically grow circular and produce an earthy, musty smell similar to the smell of decaying plants. In addition, different types of mold can appear in different colors, with black mold being the most harmful. This article will explain how to identify each color.

If you notice a red or black mold growing on your floors, there’s likely a moisture problem somewhere in your house. It would help if you got rid of it as soon as possible. The more severe the situation, the faster mold will grow. If you notice a moldy smell on your floors or your food, you’re probably dealing with Neurospora. But no matter what kind of mold you’ve found, it’s essential to identify its origin and identify it correctly.

It’s important to understand that the color of mold underneath hardwood floors varies from type to type. While some types are non-toxic, others can cause harmful reactions to humans. People with compromised immune systems and lung diseases should consult a professional for mold removal services. This is especially important for large areas of mold. And don’t forget to protect yourself and your home by wearing gloves and other protective gear. If you have any of these issues, you should consider hiring a mold remediation company.

It is important to note that mold grows in moist and humid conditions. Shower tiles are a prime example. They get saturated with steam daily, enabling mold to develop on them. This is a significant concern if you have hardwood floors, as it can trigger severe respiratory problems for people with asthma or allergies. Therefore, it’s a good idea to seek professional mold remediation if you have discovered mold under your hardwood floors. But beware: it can be challenging to remove, so it’s best to take immediate action to prevent further damage.


While cleaning up the mold yourself may be tempting, this is not an easy process. Even if you can clean up the surface mold, it is essential to kill it at its source. Mold is a tricky pest to detect because of its ability to hide. If you suspect that your wooden floors are infected with mold, it is recommended to contact a professional mold remediation service. For instance, mold can grow on your floors if moisture remains inside.

If you notice the signs of mold under your hardwood floors, the first step is to check for discoloration and fuzzy growths. Mold produces pigmented compounds that stain wood. If you notice these stains or raised textures, there is a good chance that the mold has taken hold. It may also appear as a fuzzy growth or a raised texture. In addition to color, it may be fuzzy, smooth, shiny, puffy, or any other texture.

Once you have detected the presence of mold, you need to replace the affected materials with new ones. To do this, you will need to visit your local home improvement store to purchase patching materials. In addition to patching the wood, you will need to apply a polyurethane finish to the wood. This will prevent further growth of mold and prevent it from spreading. If you’re dealing with a more significant infestation, you’ll need to obliterate the hardwood floor. Next, you’ll need a scraper to match the depth of the mold.

A musty smell is another sign of mold under hardwood floors. This smell resembles the rotting of organic matter and is often impossible to distinguish from dirt. If you notice these symptoms, you’re likely experiencing a mold outbreak under your floor. If the smell persists, a professional cleaning company can pull up the planks and check for any visible stains. In addition, you may also be able to use a particular device to detect the presence of mold by taking a sample of the air.


If you’ve recently found mold under your hardwood floors, you may be wondering how to get rid of it:

  1. Make sure you wear protective clothing when working with mold.
  2. Mix a solution of water and vinegar in a spray bottle. Spray the solution onto the affected area, and then wipe the area dry with a paper towel.
  3. Don’t walk on the moldy floor.

Walking on it may cause the mold to spread.

Another sign of a mold infestation is discolored floorboards. You may find fuzzy growth or discoloration. A simple flood event – such as a leaking sink, toilet, or overflowing tub – usually leads to an infestation. When the floorboards are discolored, you should inspect underneath the boards. A musty smell can also be an indicator of a mold infestation.

If the mold grows on the floor’s surface, it is usually easy to clean. If you notice an off-odor, it probably means you have mold on the wood. You should also notice if individual boards are pushing out from under the hardwood floor. They’ll also have an indentation down their length. This indentation will give them a “wavy” look. If the wood floor rises at the center, the area has a lot of elevated moisture.

While removing the mold from your floors may be time-consuming, you can prevent future outbreaks by following these tips. If you’ve discovered mold under hardwood floors, you’ll be able to minimize its impact on your home’s aesthetics. Using these tips, you can avoid future infestations and eliminate moderate to severe mold. So, how do you prevent mold on your floors?
