Can You Install LVP Over Existing Flooring? Tile, Vinyl, Hardwood and Carpet

Often, yes. LVP can usually go over a hard, flat, solidly attached floor like tile, sheet vinyl or hardwood. It should never go over carpet. The real questions are whether the old floor is flat enough, whether it's stuck down tight, and whether the added height causes problems at doors, appliances and the next room.

Always check the manufacturer's installation instructions for your specific product. They spell out what it can go over and how flat the surface has to be.

Over each type of floor

• Carpet. No. Carpet and pad have to come out. LVP needs a firm surface, and the locking joints will fail on something soft.
• Ceramic or porcelain tile. Often yes, if the tile is well bonded with no cracked or hollow tiles. Deep grout lines may need to be filled so they don't show through or create soft spots.
• Sheet vinyl or vinyl tile. Often yes, if it's a single layer, fully glued, and not cushioned. Thick, spongy cushioned vinyl is usually a no.
• Hardwood. Often yes, if it's nailed down tight, flat, and not cupped or squeaking badly. Loose boards get fastened first.
• Laminate or another floating floor. Generally no. Floating over floating adds movement and bounce. The old one comes out.

The height problem

Every layer you leave adds height. That shows up in places people don't expect:

• Doors that now rub and need to be trimmed
• A dishwasher that won't slide back out from under the counter
• A bigger step up at the transition to the next room
• Toilet flanges that end up too low in a bathroom
• The first and last stair treads if the floor runs to a staircase

None of these are deal breakers, but they need a plan before the first box is opened. See our post on transitions for how height differences get handled between rooms.

Why flatness matters more than the old material

Rigid-core LVP bridges small imperfections, but it doesn't bend to follow a dip. If the old floor has humps or valleys, the new floor will have hollow spots and joints that click or separate over time. Going over an old floor doesn't skip prep. It just moves it. More on that in what subfloor leveling is.

A warning about old vinyl and adhesive

Some older vinyl flooring and the adhesive under it can contain asbestos. If you have old sheet vinyl or 9-inch tiles in an older house and don't know what they are, don't sand, scrape or tear them up until you know. Covering them in place is one reason people choose to go over the old floor. Have it tested if there's any question.

When tearing out is the better call

• The old floor is loose, cracked or damaged
• There are already two or more layers
• Height would cause real trouble at doors, cabinets or stairs
• There's a moisture issue or damage underneath you need to see

Tear-out costs more up front, but it's the only way to know what's under there. In a lot of older homes around Killingly and Thompson, the floor you see isn't the first one.

What we check

At the free walkthrough we look at what's there now, check it for flatness and movement, and measure door clearances and appliance heights. Then we tell you plainly whether we'd go over it or take it out, and why. Your written fixed-price quote spells out which one we're doing.
