Luxury Vinyl Plank in Missouri: Costs, Wear Layers and Movement
Vinyl plank is the most forgiving floor you can put over a substrate that is still settling, because it is not attached to it — and in much of Missouri that is the whole argument.
What it costs
Installed luxury vinyl plank runs about $2 to $12 per square foot in Missouri. The bottom of that band is a thin floating plank with a six-mil wear layer over foam underlay; the top is a rigid-core plank with a twenty-mil wear layer, attached acoustic backing and matching stair-nose profiles. They sit beside each other in the showroom and they are not the same product.
An estimate, not a quote. These are planning ranges for Missouri, not a quote. What you actually pay depends on your rooms, your subfloor and the material you choose.
Why it suits ground that moves
A floating floor is a raft. It is not glued or nailed to the substrate, so when the substrate moves a little the floor does not have to. That is precisely the opposite of a bonded assembly like tile, which has to accommodate every millimeter the substrate does and cracks when it cannot. In a newer Missouri house on graded clay fill — Blue Springs, Lee’s Summit, O’Fallon — that difference is worth more than any feature on the box.
The trade-off is flatness. A floating floor bridges small defects and telegraphs large ones, so a dip becomes a hollow spot you hear underfoot every time you cross it. Measure with a ten-foot straightedge and budget for leveling compound if it fails.
The wear layer is the number
Not thickness, not the picture on the box — the wear layer, in mils. Six mil is a rental-turnover floor. Twelve to twenty mil is a floor someone lives on. The price gap between them is much smaller than the difference in how often you replace it.
Glue-down vinyl is a different product
Glue-down LVT is bonded, so it behaves like tile in this respect rather than like a floating plank: it follows the substrate. It has its uses — heavy commercial traffic, very large rooms, over in-floor heating — but it gives up the one property that makes vinyl plank attractive here.
Common questions
Is it really waterproof?
The plank is. The assembly is not necessarily: water that gets through the joints still reaches the subfloor and sits there. It handles spills and mopping without complaint, which is what most people mean.
Can it go over my existing floor?
Often, if the existing floor is sound and flat and the height at doorways still works. Over old tile the grout lines need filling first or they telegraph through.
Does it need an expansion gap?
Yes — a floating floor has to be able to move as a sheet. A gap held under the baseboard, not caulked solid, is what lets it.
