How To Remove Mold Under Hardwood Floors
Hardwood floors were once the most popular type of flooring used in North American Homes. As we got deeper into the 20th Century, carpets, tile, linoleum and other types of laminate flooring became increasingly popular.
Now in the 21st Century hardwood floors are enjoying a vigorous renaissance. To the point that a lot of people are tearing out old floor coverings to reveal the hardwood floors that have been waiting for them. Not to mention newer homes that had them installed from day one.
Of course, for all their beauty, the cracks, spaces, and underlayment of hardwood floors can be prone to trapping materials. This is especially true of older hardwood floors that might have minor bows or gaps greater than a millimeter between the boards. When water finds its way into the cracks or down to the underlayment of the hardwood floors it can turn into a prime breeding ground for indoor mold spores.
In a case where the mold problem is severe, and the hardwood flooring is badly damaged by water or mold infestation you might have to completely remove the hardwood floor before installing a new one. If you find yourself staring at a problem like this, you can use the following information to help guide you through the process of removing mold from under your hardwood floors.

How To Clean Mold On Wood Flooring
- about mold contamination on building floors and in floor coverings or floor materials
InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website.
This article offers advice on cleaning mold found on wood flooring, both when the flooring is already installed in a building and when wood flooring materials have not yet been installed in place.
We discuss the pros and cons of using fungicidal sealants and bleach on wood floor product surfaces including the under-side as a mold-resistance improver, and give sources and list types of those products.
We also discuss common errors made when cleaning wood surfaces, such as relying on bleach or performing expensive and unnecessary cleaning on cosmetic black mold on wood surfaces.
We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.
Answer: Physically Clean Moldy Wood Surfaces Dry The Wood Flooring Before Installation
Here we are discussing cleaning mold off of wood flooring products that have not yet been installed in a building. If your concern is with mold on the visible surfaces of wood flooring already installed in a building, or on the under-side of wood flooring or subflooring already installed in a building, the wood surface cleaning discussed here still applies, but you should also see HIDDEN MOLD in FLOOR / SUB-FLOOR. Also see MOLD CLEANUP – WOOD FRAMING & PLYWOOD where we describe methods for cleaning wood surfaces in general.
Without a mold lab test we don’t know from the moldy flooring question above if you are seeing mold or something else on soiled wood flooring, but it is reasonable to guess that a substance is mold based on its physical appearance , especially if the flooring has been exposed to water, wet conditions, or high humidity.
Except where major costs are at issue that would be effected by a determination of the type of material or mold present, or where there are other reasons to test for mold, in our opinion testing is not necessary for small mold cleanup jobs . For help in deciding if it is appropriate to test for mold, see Reasons to Test for or Identify Mold and see MOLD / ENVIRONMENTAL EXPERT, HIRE ?.
At right our moisture meter is measuring the moisture level of a different wood floor, showing that the moisture is in the danger zone for forming mold, rot, insect damage, and floorboard cupping.

How To Get Rid Of Mold On Walls
Many people first notice theyve got a mold problem when they see it growing on their walls. Check in the corners near the ceiling and floors in rooms with high moisture levels, such as kitchens, bathrooms, laundry rooms, and basements.
Youll need:
Scrubbing brush
Method:
Step 1: Make a solution of one part bleach to three parts water in the spray bottle.
Step 2: Saturate the mold and surrounding area on the wall.
Step 3: Let the solution soak into the mold for 10-15 minutes.
Step 4: Using the scrubbing brush, remove the mold and stains.
Step 5: Repeat as necessary to remove all the traces of mold and mildew.
Step 6: Make a 50/50 mixture of white vinegar and hydrogen peroxide in the second spray bottle.
Step 7: Spray the cleaned surface and allow it to absorb and air dry.
This method works because it addresses the visible mold, as well as the underlying roots that often go untreated. Surprisingly, vinegar and hydrogen peroxide are both more effective at killing mold roots than bleach. Because they work best on different types of mold, try to use them together to cover all the possible varieties of mold you might be dealing with.
Pro Tip: If you dont have hydrogen peroxide at hand, you can also clean mold with vinegar and baking soda instead.
Apply The Finish To The Wood Flooring
After all of the affected area has been completely removed and the new flooring has been installed, it will need a coat of wood finish that matches the original. If you cant find an exact match, use the lighter shade so you can darken it later. You can also add a coat of polyurethane finish for extra protection.

How Do You Know If You Have Subfloor Mold
This particular fungus can be difficult to spot, given its propensity for growing in dark, cramped spaces. Crawl spaces, in between walls, within insulation, and in the subfloor even if the contamination is out of sight, it can still affect your health.
Fungi release microscopic spores that drift through the air, or in the case of subfloor mold, up from the floor you walk on each day and into your lungs. Truly the only way to check for a spread in your subfloor is to tear up the flooring, with the help of a licensed professional of course, and visually inspect.
