Act quickly to protect your health and home
Even an innocent water spill can lead to mold forming under laminate flooring.
If your floors smell musty, that may be a sign that mold is lurking.
Hiring a professional mold remediation specialist is usually the safest path forward.
Sometimes, the biggest problems in our homes are the ones we can’t see. While your laminate flooring may look picture-perfect at first glance, mold may be lurking below the layers of flooring. Keep reading to learn how mold under laminate flooring forms, how to avoid it, and how to remove it.
Mold can develop under laminate flooring due to moisture or water exposure. Laminate flooring is made of layers of wood-based materials that are compressed together. If moisture seeps through the seams or edges of the laminate planks, it can get trapped underneath the flooring. Once moisture is trapped, it creates a conducive environment for mold growth. Mold can also form under other floor types, like hardwood floors.
Several factors can contribute to moisture accumulation under laminate flooring:
Water spills: Spills that aren't cleaned up promptly can seep into the seams, and cause mold growth.
High humidity: High-humidity levels can create moisture, especially in areas like basements or bathrooms, where proper ventilation might be lacking.
Leaks: Leaks from pipes, appliances, or the roof can introduce significant amounts of water beneath the flooring.
Poor installation: Improper installation that doesn't include a moisture barrier, or uses low-quality underlayment, can allow moisture to seep in.
Flooding: If the area experiences flooding or significant water damage, moisture can get trapped under the laminate flooring, even if it appears dry on the surface.
Inadequate subfloor preparation: If the subfloor is not properly prepared or leveled, it can create uneven areas where water can collect.
If you can smell the odor and you can’t see it, usually that is a sign of something more serious. Mold can hide behind your walls and floors and will require a professional mold remediation company to run indoor air quality tests.
To prevent mold growth under laminate flooring, it's essential to maintain a dry environment and take precautions during installation:
Use a moisture barrier: Install a moisture barrier or underlayment specifically designed to prevent moisture from seeping into the flooring material.
Proper installation: Ensure that the laminate flooring is installed correctly, with tight seams and no gaps where water can penetrate.
Regular inspection: Periodically check for signs of water damage or moisture accumulation, especially in areas prone to water exposure.
Prompt cleaning: Clean up spills immediately to prevent water from seeping into the flooring.
Maintain proper ventilation: Ensure good ventilation in areas like bathrooms, kitchens, and basements to reduce humidity levels.
Address leaks: Address any leaks in the plumbing, roofing, or appliances promptly to prevent water from seeping into the flooring.
Detecting mold under laminate flooring can be challenging because it often grows in concealed spaces where it's not visible to the naked eye. However, there are some signs of mold under laminate flooring you can look out for:
Musty odor: Mold has a distinct musty smell. If you notice a persistent musty odor in a room, it could be a sign of mold growth beneath the flooring.
Discoloration or stains: Look for any discoloration, warping, or stains on the surface of the laminate flooring. Water damage caused by mold growth can lead to changes in the appearance of the flooring material.
Peeling or bubbling: If the laminate flooring starts to peel, bubble, or lift up in certain areas, it could be due to moisture accumulation, potentially caused by mold growth.
Visible mold: In some cases, mold might grow at the edges of the laminate flooring, making it visible. Check the perimeter of the flooring for any signs of mold growth.
Allergies or health symptoms: Prolonged exposure to mold can cause allergic reactions or other health issues. If occupants of the space experience unexplained allergies or health symptoms, it could be due to mold growth.
Subfloor inspection: If you have access to the subfloor (in basements or crawl spaces), inspect it for signs of moisture, water damage, or mold growth. Mold on the subfloor might indicate the possibility of mold beneath the laminate flooring.
Professional inspection: You may be wondering, do I need a mold inspection? If you suspect mold but can't confirm its presence, consider hiring a professional mold inspector. They have the tools and expertise to detect mold in hidden spaces and can provide a comprehensive assessment. Ask for quotes from a few local specialists to get a better idea of mold inspection costs and mold remediation costs.
Removing mold under laminate flooring is a complex process that often requires professional intervention, especially if the affected area is extensive. Mold removal involves safety precautions and proper handling to prevent the spread of mold spores. Here are nine steps you can follow for removing mold under laminate flooring:
Wear protective gear, including gloves, goggles, and a mask, to avoid direct contact with mold spores and protect yourself from inhaling them.
Seal off the affected area from the rest of the house. Use plastic sheeting and duct tape to create a containment barrier, isolating the moldy area to prevent the spread of mold spores.
Carefully remove the affected laminate flooring. Use a utility knife to cut through the flooring and remove it in sections. Dispose of the contaminated flooring properly.
Check the subfloor for mold growth and moisture damage. If the subfloor is affected, it might need to be cleaned or replaced. Consult with professionals if the subfloor requires extensive repairs.
Thoroughly clean the subfloor and surrounding areas with a mold cleaner or a mixture of water and mild detergent. Use a scrub brush to remove mold from the surface. After cleaning, apply a mold disinfectant to kill any remaining mold spores.
Ensure the subfloor and surrounding areas are completely dry. Use dehumidifiers and fans to speed up the drying process. Proper ventilation is essential to prevent moisture buildup.
If the subfloor is severely damaged by mold, it may need to be repaired or replaced. Consult with professionals for this task, as improper subfloor installation can lead to future mold problems.
Install a moisture barrier or underlayment before laying new flooring. Ensure proper ventilation and address any water leaks or moisture issues promptly.
If the mold infestation is extensive or if you're unsure about the extent of the damage, it's best to hire mold remediation professionals. They have the expertise and equipment to handle mold removal safely and effectively.
Remember that mold can be harmful to your health, so if you suspect its presence, it's essential to address the issue promptly. If you find mold or significant water damage, it's advisable to consult with mold inspection professionals near you who can safely detect the mold in your home and make a plan for remediation.
