Luxury vinyl plank is the most forgiving floor most families will ever own. A tipped water bowl means nothing to it, it cleans with a damp mop, and there is no finish to wear through. So when one starts peaking in August, ticking underfoot or opening at the joints, people assume they got a bad batch of plank.
Usually they did not. Nearly every vinyl floor problem we are called out to in Forney, Terrell, Rockwall and around Kaufman County traces back to one of three things: the floor was pinned, the slab under it was not flat, or the room is asking more of vinyl than vinyl gives. Here is how to read the symptoms.
First, make sure it is vinyl
Laminate and vinyl plank look alike once they are down, and they fail differently. Two checks:
- Tap it. Laminate rings slightly hollow and bright. Vinyl answers with a duller, softer sound.
- Look at a cut edge where a floor register exposes one. Laminate shows a brown compressed fiber core. Vinyl shows a uniform gray or off-white composite.
If it is laminate and the edges are raised along the seams, that is almost always water at a seam. A fiberboard edge that swells does not go back down, so those planks get replaced. Laminate does not move seasonally the way wood does, so if it is lifting without water involved, it has usually been pinned, which is the next section. Laminate floor problems covers laminate in full. The rest of this post is about vinyl.
Peaking in summer: the floor was pinned
Peaking is two planks pushing up against each other at a joint so the seam rises into a ridge. It usually shows up in the middle of a room, and usually in the heat of summer.
A floating vinyl floor is not fastened to the slab. It moves as a single sheet, expanding when the room gets warm. To allow that, it needs a gap at every wall, door jamb, toe kick, hearth and pipe, hidden behind trim rather than eliminated. When that gap is missing, or something heavy is sitting on the floor, the field has nowhere to go and buckles up at the weakest joint.
The usual culprits:
- Plank run under a kitchen cabinet run or an island. A bank of cabinets carrying a stone countertop pins the floor down, and the planks peak out in the open floor a season later. A floating rigid core floor should stop short of cabinets and islands, with the toe kick covering the edge.
- Trim or door jambs pressed tight against the plank, with no gap left.
- A very long open run with no break. Floating fields have limits on how far they can run, which is one of the places glue-down earns its keep.
When planks peak in the middle of a room in August, it is almost never a defective product. It is a floor that was given nowhere to go. The fix starts with finding where it is pinned and freeing it. Kitchen flooring on a North Texas slab covers the cabinet question in detail.
Springy, ticking or opening joints: the slab is not flat
A rigid core plank is four to six millimeters thick, and it bridges nothing. Lay a floating floor over a dip and it reproduces the dip. In the hollow the plank is unsupported, so it feels springy and ticks when weight crosses it. Within a year or two, the locking joints over that spot work loose and open.
Manufacturers publish a flatness tolerance, commonly three sixteenths of an inch over ten feet, and it is a condition of the warranty. On the Blackland clay under these houses, the ground swells and shrinks with the seasons, and slabs crown and dip with it. A fifteen-year-old house in Terrell can sit well outside that tolerance and still look level to the eye.
The prep that prevents it is grinding high spots down and filling low spots with patch, or pouring self-leveling underlayment where a whole room is out, before the plank goes down. Skipped prep rarely shows on handover day. It shows up around the twelve-month mark.
A hard bump or a worn stripe: something under the floor
Two symptoms point straight at what was left on the slab.
- A small, hard bump you can feel underfoot, often in a room that used to be carpeted. That is frequently a staple from the old carpet pad that was never pulled. It telegraphs through the plank and can eventually wear a hole in it from below.
- A stripe worn through the print down a walkway. That points to a high spot under the floor that every footstep grinds against.
Both come down to removal and prep. Floor removal and demolition explains why that step is worth doing slowly.
Fading by the window
This one is the plank, and it is the complaint we hear most about vinyl in this part of Texas. The wood image is a printed layer under a clear wear layer, and hard afternoon sun through a west-facing window lightens it over years. You notice it most when a rug that shaded part of the floor gets moved.
Solar screens, low-E glass or a shade drawn during the worst hours slow it down. Direct sun also heats the plank enough to move it, which feeds back into peaking. SPC, the dense stone-plastic core, is much more stable in a hot room. WPC, the foamed core, expands more and is a poor choice behind south-facing glass.
Scratches, gouges and dents
- Scratches. The clear wear layer on top, measured in mils, is what takes abrasion. A scratch that gets through it is permanent, because there is nothing below it but the printed image. A heavier wear layer is the prevention. Vinyl flooring maintenance covers the day-to-day side.
- Dents. WPC is softer and quieter underfoot but dents more readily under concentrated weight. SPC shrugs off a refrigerator foot or a piano leg.
- Gouges. One plank can be replaced without redoing the floor. On a glued floor the damaged plank is cut free and reset in fresh adhesive. On a floating floor it is unlocked back from the nearest wall, or cut out and replaced with a glued-in board. Keep a carton of leftovers, because dye lots shift over time.
Water under the floor
The plank is waterproof. The installation is water resistant. Spills, mopping, a messy dog and a bathroom floor are all fine indefinitely. A supply line that lets go overnight is different: water runs to the perimeter gap and sits on the slab under a floating floor. It has to come up so the slab can dry. Vinyl survives that far better than laminate or wood does.
The hollow tap
Some things are just what the product is. In a large open room, a floating vinyl floor can sound like what it is: a hollow tap under a hard heel. A glue-down plank sounds more solid, which is one reason it suits long open runs.
