Removing Black Mold Stains On Hardwood Floors
You can tell that the dark stains on your wood flooring are due to mold growth and not pet urine through the differences in odor. While pet urine has a strong, ammonia smell, mold spores carry an earthy, musty smell. Mold can trigger various health issues and should be controlled as soon as its discovered. To get rid of black mold stains on your hardwood floor, follow the procedure detailed below:
- Remove the Hardwood Planks
Whenever you notice black mold stains on your wood floor surface, its highly likely that the problem started out from the subfloor. You should, therefore, start by uninstalling the hardwood planks to access the subfloor.
Start by removing the baseboard trim and transitional trims. Then, take out the hardwood planks one by one. This takes some elbow grease, especially of the planks that were nailed down to the subfloor. However, its important if you want to completely get rid of the mold problem.
- Clean the Subfloor using Vinegar Solution
Once you access the subfloor, the mold-infested sections will be easily noticeable. Before using vinegar, wear a pair of hand gloves, as prolonged exposure to this natural acid can trigger skin irritation. Mix a cupful of distilled white vinegar with a gallon of water inside a mop bucket. Then, stir the mixture.

Mold On The Underside Of Wood Flooring
One of the hardest issues to find and treat is when wood flooring mold problems are on the underside of the hardwood. Until you begin to notice musty odors or warping begins to show on the hardwood floor itself, you may not realize there is a problem. When moisture becomes trapped under a floor, the wood begins to slowly absorb it. As the boards absorb the water they expand and begin to warp. Hardwoods normally have moisture content levels of 10% or less. Once moisture content levels reach 18% or higher, there is a strong chance for mold to grow.
The only way to find a wood flooring mold problem that is under the hardwood is to physically look for it.

Watch out: often mold-stains penetrate rather deeply into wood materials. While the stain does not itself signify an increased risk of future mold re-growth, its appearance may be unacceptable. But deep stains can require removal of quite a bit of wood surface – something that can be a problem in wood flooring, and in particular if the flooring is a Vee-grooved pre-finished product.
