While Luxury Vinyl Plank (LVP) is highly water-resistant and its core won't rot, a significant flood is still a major problem. The planks will usually survive, but water trapped beneath them creates a hidden breeding ground for mold that requires pulling up the floor to properly dry.
To get water out from under your vinyl plank flooring (LVP), you must stop the leak, remove standing water, and carefully pull up the affected planks so you can dry and disinfect the subfloor before mold takes hold.
Luxury Vinyl (LVP & LVT)
If you catch the issue early, you may be able to lift the affected planks, dry the area beneath, and reinstall them without long-term damage. However, if the water has been sitting for more than a day or has reached the subfloor, repairs become more complicated.
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.
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.
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.
Some Luxury Plank Flooring Is Waterproof
While it does well at avoiding damage from household spills or excess moisture from a shower, not all vinyl is entirely waterproof. If you clean up spilled water in a timely fashion, then it's unlikely there will be any visible damage.
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.
Yes. Both dry and wet Swiffer mops are safe to use on vinyl plank, as long as you're using cleaning pads that don't leave behind residue. Just avoid soaking the floor.
Dust, adhesive residue, and paper-backed underlayment can all feed mold under your floor. Add trapped moisture and a warm room, and mold can start forming fast. According to FEMA, mold can begin growing on damp surfaces in as little as 24 to 48 hours. That's why what happens before your vinyl goes down is so important.
While luxury vinyl flooring (LVP/LVT) is highly popular due to its waterproof nature and cost-effectiveness, it has notable drawbacks. Key disadvantages include susceptibility to dents and scratches, challenging joint failures on uneven subfloors, poor home resale value compared to natural hardwood, and environmental concerns regarding its PVC composition.
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)
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.
Luxury vinyl is typically water-resistant and sometimes even waterproof on the surface, but problems can arise if water gets underneath. If you catch the issue early, you may be able to lift the affected planks, dry the area beneath, and reinstall them without long-term damage.
The best months to buy flooring are late December through February and mid-May to early June. During winter, flooring stores clear out old inventory with deep discounts—often 15–30% off.
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.
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.
Yes, water can easily get under vinyl plank flooring. While the vinyl planks themselves are 100% waterproof and won't be ruined, water can seep between the seams, around unsealed perimeters, or along walls. Because vinyl acts as a vapor barrier, trapped water cannot evaporate, which risks damaging the subfloor and causing mold.
Installing 2,000 square feet of vinyl plank flooring takes about 3 to 7 days total. A professional crew of 2-3 installers can typically lay 400 to 1,000 square feet per day, but you must also factor in a 48-hour acclimation period and time for subfloor preparation.
The best mop for vinyl plank flooring is a microfiber flat mop (or a gentle spray mop). It cleans without scratching the wear layer and allows you to control moisture, preventing standing water from seeping into the joints and causing planks to swell or warp.
Avoid using harsh chemicals, excessive water, or abrasive tools on vinyl plank flooring, as these can strip the protective wear layer, dull the shine, or cause planks to warp.
The best cleaners for luxury vinyl plank (LVP) flooring are pH-neutral, ready-to-use formulas that dry without leaving a dull residue. Top-recommended commercial products include Bona Hard-Surface Floor Cleaner and Rejuvenate Luxury Vinyl Floor Cleaner.
Yes, Luxury Vinyl Plank (LVP) is used in luxury and high-end homes, but primarily for practicality rather than prestige.
