LVP Problems Homeowners Complain About, and Which Ones Are Installation Mistakes

Luxury vinyl plank is a practical, good-looking floor that handles everyday life well when it's installed and cared for properly. Search for LVP problems and you'll find the same complaints again and again: gaps between planks, buckling, dents, fading, and water trouble on a floor sold as waterproof. Many of them trace back to a handful of things that are easy to understand and easy to prevent. Here's what's behind each one, so you know what to ask before the first plank goes down.

One thing to know up front: many LVP products are floating floors. The planks lock together and aren't attached to the subfloor, so they're designed to move a little as temperatures change. Others are glued down. Either way, requirements differ from one manufacturer to the next, so the numbers below are examples. The installation guide for the specific plank you choose is the rule.

Gaps Between Planks

This is the most common complaint, and it's usually about movement. Shaw's installation guide for its floating plank says improper acclimation or temperature control can make the floor expand or contract and cause gapping. The fix is on the front end: the guide calls for acclimating the planks for 48 hours in the room where they'll be installed and keeping the room between 65°F and 85°F. Other manufacturers' guides we reviewed give the same 48 hours and similar temperatures.

Movement also gets restricted by things on top of the floor. Shaw says cabinets and fixed objects must not be installed on top of a floating floor, and another manufacturer, Cali, notes that furniture over 500 pounds can restrict the natural movement of a floated floor. Shaw's guide says slight gaps can be tapped closed, but a gap that keeps coming back is worth a look at what's going on underneath.

Buckling and Peaking

When a floating floor has nowhere to expand, it can lift. That's why manufacturers specify an expansion gap at the walls. The guides we reviewed call for roughly 5/16 to 1/2 inch, depending on the product, and one adds that baseboards must not be fitted too tightly and that nothing should be nailed through the flooring. The gap is hidden by trim, so it's an installation detail you can't see afterward, which is a good reason to ask about it up front.

Heat is the other factor. Several manufacturers warn that long periods of direct sunlight can cause the planks to expand, and recommend curtains or blinds during peak sun hours. Chesapeake also lists solar window film. If you have a sunny room with big windows or a sliding door, plan for that.

Bumps, Ridges, and Uneven Spots

Planks follow the floor underneath them, which is why manufacturers set flatness limits. Several guides allow no more than 3/16 inch of variation over 10 feet. Flooret's guide says a gradual, consistent slope is fine, but unexpected rises and valleys cause problems. The fix happens before installation: high spots are sanded or ground down, and low spots are filled with a patching or self-leveling compound. Flooret is explicit that underlayment isn't a correction tool, so the subfloor itself needs to be right first.

Dents and Scratches

This one is about daily life more than installation, and LVP handles it well with a few habits. Manufacturers recommend felt-tipped, non-staining protectors under furniture legs, at least 1 inch across, and soft casters at least 2 inches wide on rolling furniture. Heavy pieces should be lifted or moved with dollies or glides instead of dragged. For light surface scratches, some manufacturers sell a scratch concealer made for LVP, and Cali's guide says a plank scratched through to the decorative layer can be replaced rather than the whole floor.

Fading, Discoloration, and Rug Damage

Shaw says prolonged direct sunlight can discolor the planks. Window coverings or film handle most of it. Rugs matter too: Cali's care guide says not to use rugs with solid rubber or vinyl backings because they may damage the finish, and recommends breathable rugs on a mesh or grid underlay.

“It's Waterproof, So Why Is There Water Damage?”

Waterproof planks are great for spills, kitchens, and bathrooms, and they shrug off everyday messes. The confusion is about what waterproof covers. A Cleanfax article on the topic points out that the warranties it looked at refer to water on the surface, and exclude water coming from underneath or flowing over the edge. It also notes, citing a restoration expert, that seams and joints can let water seep beneath the surface, especially in floating installations. So the plank may be fine while the subfloor or adhesive isn't.

That's why moisture is checked before installation. On concrete, a relative humidity test is the usual method, and the limits vary a lot by manufacturer: one guide we reviewed allows a maximum of 55% and another 85%. An article from a moisture-meter company says concrete dries from the surface down, so a slab that seems dry on top may hold substantial moisture below, and warns against assuming waterproof flooring makes testing unnecessary. If your home has a crawl space, Shaw's guide calls for 6-mil polyethylene covering all the exposed earth, with ventilation. In bathrooms and other wet areas, it calls for caulking the perimeter with silicone.

Day to day, Cali's care guide says to soak up spills right away and never to use a steam mop or wet-mop, since standing water may cause permanent damage even on waterproof planks.

So Which Ones Are Installation Mistakes?

The manufacturers' installation guides put these on the installer's checklist: acclimating the planks and controlling room temperature, leaving the expansion gap at the walls and not pinning the floor with trim or cabinets, checking the subfloor for flatness, and testing for moisture before installing.

These come down to how the floor is used and cared for: furniture pads and casters, sun control, rug choice, and keeping standing water off the floor.

This one is mostly about expectations: what “waterproof” does and doesn't cover.

Products differ, too, so read the warranty and installation guide for the specific plank you pick before you buy.

Questions to Ask Before Your LVP Is Installed

How will the subfloor be checked for flatness and moisture, and what happens if it doesn't pass? How long will the planks acclimate, and at what room temperature? What expansion gap will be left, and how will the trim be installed so the floor can still move? Are cabinets or an island going on top of the floor? Which manufacturer's installation guide is being followed? An installer who can answer these easily is usually one who's done the prep work many times.

What We Look At on a Free Estimate

When we look at a space for LVP, we start with what's underneath: whether the subfloor is concrete or wood, whether it's flat, and whether there are signs of moisture. We ask about sun exposure, cabinets, and heavy furniture, since those affect how the floor needs to be installed. If the subfloor needs work first, we'll tell you plainly and explain why.

Our Recommendation

If you like LVP, buy it with confidence. It's a good floor. Put as much thought into who installs it and how the subfloor is prepared as you do into the color. Ask the questions above, follow the manufacturer's guide for care, and protect the floor from sun and heavy loads. We're happy to talk it through on a free estimate.
