The Hidden Dangers of Luxury Vinyl Plank on Top of Wood Floors
Installing luxury vinyl plank on top of wood floors is one of the most damaging mistakes we see in modern home renovations. Homeowners often choose this route to save time on demolition, assuming that covering the old floor is a harmless shortcut.
However, as the photo reveals, this decision often leads to catastrophic failure. If you are thinking about laying LVP over existing hardwood, you need to understand the science behind the rot.

Why Luxury Vinyl Plank on Top of Wood Floors Fails
To understand the failure, you must look at physics. As noted by the National Wood Flooring Association, wood is hygroscopic—it needs to breathe.
Modern LVP is designed to be waterproof and often includes a rubber backing. When you layer this impermeable material over organic wood, you effectively seal the subfloor. This creates a “suction cup” effect, trapping rising moisture between the layers.
Health Hazards & Structural Decay
The moisture trapped by the vinyl creates a stagnant micro-climate. This dark, damp environment is the perfect breeding ground for mold and bacteria. The EPA warns that hidden mold behind building materials poses serious health risks.
Structurally, the wood begins to rot, swell, and buckle. You may eventually hear crunching sounds or feel soft spots. These are clear signs it is time to replace your flooring immediately to prevent damage to your home’s joists.
The Solution: Removal, Not Cover-Up
The only safe way to upgrade your floors is to remove the old hardwood first. Putting luxury vinyl plank on top of wood floors might save a few hundred dollars today, but it often costs thousands in remediation later.
Don’t risk your home’s health. Ensure your investment lasts by using professional removal solutions to start with a clean, dry, and solid foundation.
