Fixing Luxury Vinyl Plank (LVP) water damage usually requires drying the subfloor and replacing the warped or buckled planks. Because vinyl is waterproof, the planks themselves may only need replacing if they are physically damaged or warped, but the subfloor underneath requires immediate attention to prevent mold and rot.
"Good news! You can, in fact, replace damaged click luxury vinyl planks without needing to unclick your entire floor. However, the process does take some finesse and we recommend hiring a professional installer for the work."
The vinyl itself may resist moisture, but the surrounding components often do not. When water becomes trapped between the flooring and the subfloor, it has nowhere to evaporate. This trapped moisture can lead to a range of structural and environmental problems, including: Adhesive failure in glue-down installations.
Short answer: yes, mould can grow under vinyl flooring — but only when moisture gets trapped between the planks and the subfloor. Vinyl itself is non-porous, so the planks don't host mould.
LVP does have a water-resistant surface, but it is laid on top of the underlayment and subfloor, which can suffer from water damage. Water damage to vinyl plank flooring can cause the core material of the flooring to expand, resulting in warping, buckling, and even layer separation within the vinyl planks.
Look for: Permanent water stains and unsightly mold water damage markings on ceilings, walls and floors. Erosion of drywall, often causing it to be warped or changed in texture (TIP: newer water spots will feel firm to the touch, while older water damage will create a spongy, mushy feeling)
Make sure the floor is dry before attempting to replace or repair buckling on your vinyl floor. Cut out the damaged vinyl then pry it off the floor using a screwdriver. You can replace the damaged part or reuse the vinyl.
If your house smells musty, or you notice discoloration on your flooring, you may have mold under your vinyl flooring. Mold seldom remains hidden for long, so if you see mold creeping up from under your vinyl flooring–you're probably looking at a much bigger problem.
Luxury Vinyl Plank (LVP) flooring typically lasts 15 to 30 years, depending on the quality of the planks, the thickness of the wear layer, and foot traffic.
Early signs of mold exposure frequently mimic seasonal allergies. They include sneezing, a runny or stuffy nose, coughing, postnasal drip, and red, itchy, or watery eyes. Skin irritation or rashes may also occur, and mold can trigger or worsen asthma symptoms like wheezing and chest tightness.
A wet subfloor is not automatically ruined. Plywood or Oriented Strand Board (OSB) can handle exposure to water, provided it is dried out completely and retains its structural integrity. However, it must be replaced if it becomes soft, spongy, warped, or shows signs of rot.
Water can sit on the surface of Luxury Vinyl Plank (LVP) flooring for 24 to 48 hours or more without causing damage. However, because LVP features a click-lock installation, water can seep through the seams if left too long, causing mold, subfloor damage, or edge-peaking.
Yes, Dawn dishwashing soap can be used to clean luxury vinyl plank flooring. Just add a few drops to a bucket of warm water. This mixture is excellent for removing grease and grime, especially in kitchens. However, be cautious not to use too much soap, as it can leave a film that dulls the floor's shine.
Water trapped under a vinyl plank floor will rarely dry out on its own. Because vinyl is non-porous and the planks fit tightly together, airflow is completely blocked. This prevents evaporation, leading to trapped moisture that will quickly cause mold, mildew, subfloor rot, and foul odors.
In 2026, flooring trends revolve around warmth and natural textures, with cool, flat grays officially on their way out. The most popular colors include:
While it is possible to remove and reinstall vinyl plank flooring, there are challenges you may encounter: Damage During Removal: The edges of vinyl planks can be easily damaged during removal, especially with glue-down flooring. Damaged planks may need to be replaced rather than reinstalled.
Additionally, spraying a solution of equal parts vinegar and water or a diluted hydrogen peroxide solution into the air can help to kill airborne mold spores.
Symptoms of mold toxicity
Prolonged exposure to mold can lead to chronic health issues and exacerbate existing conditions due to long-term inflammation from constant immune system activation. Inflammation as a result of exposure to mold or mycotoxins can be an acute episode of illness or delayed over weeks to months.
Flushing mold (mycotoxins) out of your system requires a combination of removing the source of exposure, supporting the body's natural detoxification pathways (liver, kidneys, gut), and using binders to escort toxins out. Key strategies include hydration, eating anti-inflammatory foods, using supplements like activated charcoal or glutathione, and sweating.
The versatility of LVP, particularly in mimicking the look of authentic wood or stone, has made it a favored choice both for higher-end homes and more affordable ones. “I love LVP flooring that mimics wood or stone, especially the wide and long planks. And so do buyers.

Dawn dish soap does not kill mold, but it acts as an effective surfactant to lift and scrub visible mold away from non-porous surfaces. While it washes away the active growth and prevents airborne spores from releasing, you must use a disinfectant afterward to ensure the mold roots are destroyed.
Mold toxicity (or mycotoxin illness) occurs when you are exposed to mold spores that produce toxic byproducts. These symptoms can mimic other conditions and often range from mild respiratory irritation to severe neurological and immune responses.
Spray the affected area with the vinegar and let it sit for an hour to allow the vinegar to penetrate the surface and kill the mold at the root. Rinse the surface with warm water, spray again with vinegar, and allow to dry. -Hydrogen peroxide can remove mold.
