Step-by-step Guidelines on How to Get Rid of Mold Under Flooring

Step 1: Identifying the Type of Mold

Before you begin the cleaning process, it’s essential to determine what type of mold you’re dealing with. There are various types of mold that can grow under flooring, and some are more dangerous than others.

The most common types found in households include Aspergillus, Cladosporium, Penicillium, and Stachybotrys (also known as black mold). Identifying the type of mold you have will help you take appropriate measures for removal and prevent future growth.

Step 2: Wear Protective Gear

Mold can cause severe health issues if inhaled or touched, so it’s crucial to wear protective gear throughout the entire cleaning process. This includes gloves, a mask or respirator, safety glasses, and disposable overalls. Covering your skin will protect you from coming into direct contact with the mold spores.

Step 3: Contain the Area

To prevent the spread of mold spores to other parts of your home, it’s important to contain the affected area. Close off all doors and windows leading to the room where you’ll be removing the mold, and cover any vents or ductwork to stop the spores from spreading through your HVAC system.

Step 4: Remove the Affected Flooring

If you have carpeting or rugs, it’s best to remove them entirely. For hard flooring such as tile or hardwood, you may need to lift a few pieces to check for mold growth underneath. In severe cases, you may need to remove some or all of the flooring material. While removing the flooring, be careful not to disturb any mold colonies as this can cause the spores to spread.

Step 5: Scrub and Disinfect

Use a mixture of warm water and detergent to scrub the affected area thoroughly. This will help to remove any visible mold growth on the surface. Once done, disinfect the area with a commercial mold cleaner or a DIY solution of bleach and water. Make sure to follow the instructions on the product carefully and use it in a well-ventilated area.

Step 6: Dry the Area

After cleaning and disinfecting, make sure to dry the area completely. Use fans or dehumidifiers to speed up the process as mold thrives in damp conditions. Drying the area will also help to prevent future mold growth. Make sure to monitor the humidity levels in your home regularly and maintain them below 50% to prevent mold growth.

Step 7: Dispose of Contaminated Materials

All materials used in the cleaning process, such as rags, sponges, and protective gear, should be disposed of properly to prevent further contamination. Seal them in a plastic bag and dispose of them in an outdoor trash bin. Before removing your protective gear, make sure to wash them thoroughly and disinfect them.

Step 8: Get Professional Help

In cases of severe mold infestation or if you have health concerns, it’s best to seek professional help. A certified mold remediation specialist will have the necessary equipment and expertise to safely remove the mold and prevent future growth.

Following these steps will help you get rid of mold under flooring effectively. However, it’s essential to address any moisture issues and take preventative measures to prevent future growth. Don’t ignore signs of mold and act quickly to protect your home and family from harmful effects of mold.
