Mold on Wood Floor

“Hardwood floors are among the most reliable and durable flooring materials available, but they must be properly maintained and cared for to last as long as possible. In the case of wooden floors, mold can develop after a long period of use, especially if they consist of organic materials.”


Mold on Wood Floor


To properly remediate Mold on Wood Floor, you need to identify it as soon as possible. Moldy wood floors can develop for various reasons, all of which might go unnoticed or unattended.

For instance, a slow water leak creates a wet environment perfect for mold growth. Mold is not uncommon on underwood floors over time. Likewise, spills can find their way under floorboards after repeatedly soaking into crevices. Lastly, poor ventilation can lead to mold growth.

As with all organic materials, wood floors are susceptible to mold growth and spread in humid, wet environments. As mold grows in wood flooring, it can harm home occupants’ health and the wood itself.

Replacement of moldy wood floors is certainly an option, but it does not always resolve the problem of mold infiltration. It would be best if you had a professional’s attention here.


How do we know if there is mold under wood floors?

If you suspect mold under your wood floors, you may have noticed several signs and indications. At this point, you can determine whether mold has grown under the floors and how widespread the mold is. Wood floors usually show specific signs of mold under them.


Musty smells or odors

Any musty smell or odor in your home could indicate mold has either grown or already established itself. During mold growth, certain gases can be present, easily contributing to stale, musty, and even rotten odors.


Existing water damage

The presence of visible water damage indicates the presence of mold. Leaving water damage unattended can make wooden floors feel spongy (an ideal breeding ground for mold). There is also a possibility of water damage based on water stains.


Under the floorboards

A mold remediation specialist knows what to look for under the floorboards, which may be the best place to find the most tangible signs of mold. The specialist can also assess the extent of mold contamination.


Is mold under wood floors dangerous?

If you have discovered mold beneath your wooden floors, you should know it takes work to cleanse. Surface mold is probably easy to clean, but killing the mold at the source is the key.

Detecting the full extent of mold infiltration is difficult simply because mold tends to hide. Hence, a full assessment by a mold remediation specialist is necessary. Mold growth indicates the presence of an outgrowth.

The growth could be problematic based on its scope, especially if it poses health risks to the home’s occupants. People allergic to mold (or mycotoxins) may experience sinus stuffiness, coughing or wheezing, skin irritation, eye irritation, or other symptoms resulting from mold spores (or mycotoxins) reaching the air.

Young and older adults may be at a greater risk of serious mold-related harm. This depends on the level of mold in the home and the duration of exposure. Although most mold species do not pose health risks to humans or pets, mold infestations should generally be removed. Professionals can eliminate pests.


How can we clean mold under wood floors?

When it comes to mold cleanup, doing it yourself is a good idea if you have surface mold. Furthermore, we need special protective gear and expertise, but the health risks are unjustifiable. Leave mold removal to an expert.

Performing a mold cleanup as a DIY project is just too complicated. Identifying how much mold is growing is the first step. The second step is determining whether water leaks, high humidity, or other factors cause dampness. As a third step, ensuring a thorough cleanup is essential.

In all mold cleanup cases, we should avoid DIY methods. The mold may return after the cleanup, so the cleaning will only have a short-term effect. Meanwhile, professionals know how to apply appropriate methods for removing mold and preventing recurrences.

Professionals are equipped with all the necessary equipment, expertise, and experience to ensure long-term success. By dealing with mold and mold spores, they can prevent cross-contamination between different parts of the home. Mold remediation needs to be completed correctly the first time.

Removing mold from wood floors is possible if it covers only a few square feet or less; otherwise, you should hire a professional mold remediation company. Typically, they have the products necessary for removing mold from large areas once it has spread.


Wear personal protective gear when removing mold.

Professionals wear proper safety equipment whenever mold remediation occurs to prevent health risks. The symptoms include sneezing, coughing, itchy and watery eyes, and breathing difficulties. If you wear eyeglasses, a breathing mask, gloves, and washable clothing during the cleaning process, you will remain safe from any harmful spores that may be released.


Choose the appropriate mold and mildew cleaner.

You must choose a cleanser for the remediation process so that the fungus is completely removed rather than just irritated. To remove surface mold, buy a chlorine bleach solution from your local hardware store with a 10:1 ratio of water to bleach.


How to clean surface mold from wood floors

Mold on surfaces is not difficult to remove, but it is important to ensure that all affected areas are cleaned thoroughly so that the fungus doesn’t return. After applying the cleaning solution, allow the bleach cleaner to sit on the damaged surface for 10 minutes. Throw away the old rag after you have removed the mold with it.


How to clean surface mold from wood floors.


To remove stubborn stains caused by mold, you can use a scrub brush with strong bristles. However, to prevent the finish from being ruined, avoid rubbing the cleaner into unaffected areas of the wood during the cleaning process.

Lastly, you must ensure that you rinse the solution properly before proceeding to the next step, as this will compromise the finish.


Best Way to Clean Deeply Penetrated Mold from Wood Floors

Water damage that went unnoticed or untreated for a long time is most likely to have caused mold to penetrate deep within wood floors. Calling a water damage restoration professional is necessary if you see any other water damage in your home or face another mold problem.


Determine how far the mold has penetrated.

Mold can penetrate deep within building materials, such as wood floors, without being visible. To see how far it has spread, use a screwdriver to press into the affected area.

If the wood below the floorboards is soft and spongy, a problem may exist, requiring the board’s replacement. Here are the steps to remove mold from wood floors.


Allow air to flow throughout the area.

Remove the moisture from the mold’s source as the first step to removing it. Set up a fan in the room or turn on your overhead fan or furnace to allow air to flow throughout the area, evaporating moisture. It would help if you only placed them slightly away from the mold to avoid irritating it even more. Run them for three to five hours.

  • To prevent future mold growth, remember to increase airflow.
  • After the area has completely dried, begin cleaning it.


Wear protection equipment during the process.

Since the fans blow air around, mold spores will spread to other areas. When you are not wearing eyewear or a breathing mask, these spores trigger allergies and breathing problems. Protect yourself properly. Additionally, you can ventilate the area by opening all windows and doors.


Remove the surface area of mold from the wood floor.

Sandpaper with a 100-grit rating should scrape away the surface mold after it has dried completely. Once the fungus has penetrated the wood, use 200-grit to scrape it away. Using a metal spackle blade, you can remove mold from the deepest areas of the house. After you have completed the project, use 200—or 250-grit sandpaper to smooth out the area.


Apply chlorine bleach to the affected area.

Spray the affected area with a chlorine/bleach solution in an 8:1 ratio as soon as it becomes smooth. Then, wipe up the cleaner with an old rag, removing any live mold that is still present. Even after cleaning all areas, mold can still be alive.

By removing the leftover mold spores, the cleaning solution will prevent future mold growth.


Cut out wood flooring affected by mold.

Wood flooring penetrated by mold affecting the baseboards is most likely not reversible. Using a utility knife will help you remove it. Cut carefully around the affected area and immediately dispose of the materials in a garbage bag.

When finished, throw away the bag. It will then be necessary to replace the floorboards.


Apply the finish to the wood flooring.

After removing damaged areas and installing new flooring, the wood finish must be the same as the original. It is best to use the lighter shade if you are still looking for an exact match because you can darken it later. An extra layer of protection is necessary with polyurethane.


Dispose of all tools and materials.

Please dispose of the old tools immediately. Bacteria and spores from the old flooring have contaminated them, and taking this step now will help you avoid mold later.

The new flooring will no longer be susceptible to mold growth. Additionally, allergic reactions and respiratory issues should no longer concern you and your family.


Vinegar removes mold from wood.

These steps will help you clean your hardwood floors of mold. Moreover, you can also remove mold from wood cabinets using this method.

Protect yourself from mold by wearing all the necessary protective equipment, such as gloves, goggles, masks, etc. Getting sick while cleaning mold off your hardwood floors would not be a good idea.


Vacuum the hardwood floor.

The vacuum machine should have a HEPA filter. After vacuuming, remove all loose spores from the affected area. Using a sealed plastic bag, dispose of the vacuum outside your home.


Time to get rid of mold

Over 80% of mold decomposes by distilled white vinegar. Make a spray bottle by mixing vinegar with warm water. After spraying the solution over the mold, let it sit for an hour. Dry the surface after cleaning it with a wet cloth.


Sand the floor only if need be

If the vinegar-water solution does not eliminate mold, sand the flooring.
