The short answer
Luxury vinyl plank is largely unaffected by water but is impermeable, so it traps moisture in the subfloor beneath and usually has to be lifted to dry that layer. Both are floating floors, which makes removal and reinstallation easier than glued systems.
Laminate: the core is the problem
When it absorbs water it swells, particularly at the edges and the locking profile, and that swelling is permanent.
Affected planks are generally removed. Occasionally a small number of planks can be replaced from an offcut, which is why keeping spares from an installation is worth doing.
LVP: the floor is fine, the subfloor is not
Vinyl plank is not damaged by water. It is also effectively impermeable, so water that gets beneath it, from a leak at the perimeter, or from below, has no path out.
That is why LVP is commonly lifted after a loss even though the planks themselves will be reinstalled. The lifting is to dry the subfloor.

The layer in between
Both systems usually sit on a foam or fibre underlayment, which absorbs and holds water and is generally removed instead of dried.
That layer is cheap to replace and impossible to verify in place, which makes the decision straightforward.
Why floating floors help
Neither system is glued down in most installations, which changes the economics of the whole loss.
- Planks can be lifted from a wall and reinstalled
- The subfloor can be dried properly rather than through the finish
- Undamaged planks are frequently reusable
- Removal does not damage the subfloor the way scraping adhesive does
- Reinstallation is faster than a glued or nailed system
Signs that water has reached it
Edge swelling and peaking at plank joints indicate laminate core damage. Movement, lifting or a change in how the floor sounds underfoot can indicate moisture beneath either system.
With LVP, the planks may look and feel entirely normal while the subfloor below is saturated.
Reinstalling too early
Putting a floating floor back over a subfloor that has not reached its drying goal traps the moisture again, with an impermeable layer on top in the case of LVP.
Confirm subfloor readings before reinstatement, and get them in writing.
A common choice in Vermont basements and rentals
Luxury vinyl plank has become a common choice in Greater Burlington basements and rental units precisely because it tolerates moisture, and that creates a specific trap: the flooring survives a basement water event perfectly while the subfloor or slab beneath it stays wet indefinitely.
In a basement over a slab, that combination is how a floor that looks fine sits over a slab that never dries. Where LVP is used below grade, checking the substrate after any water event matters more than inspecting the floor.
Laminate and LVP compared
The two floors fail in opposite ways.
| Feature | Laminate | LVP |
|---|---|---|
| Core | Wood-based, swells | Largely unaffected |
| Typical outcome | Affected planks removed | Often lifted to dry the subfloor |
| Main problem | Irreversible swelling | Traps moisture beneath |
| Reinstall | After subfloor is dry | After subfloor is dry |
Clear answers
Common questions
Is LVP damaged by water?
The planks themselves generally are not. The problem is that they are impermeable, so water beneath them cannot dry out, which is why they are usually lifted.
Does the underlayment need replacing?
Generally yes. Foam and fibre underlayments absorb and hold water and cannot be verified in place, so they are removed instead of dried.
Can I reuse the planks?
With LVP, commonly yes. With laminate, only planks that were not wetted. Floating installation makes lifting and reinstalling practical either way.
Can laminate flooring be saved?
Rarely. The core swells irreversibly once water reaches it and the planks do not recover. Some vinyl products fare better, but what is beneath them still has to be dried.
Water got under my LVP but the planks look fine. Is that a problem?
Yes. The plank being unaffected is exactly the issue. The water underneath has nowhere to go and nothing shows on the surface while it sits there.
