Can You Install LVP Over Existing Flooring? Tile, Linoleum, Vinyl and More

Going over the old floor saves demo time and money, and sometimes it's the smartest move. But it doesn't skip prep. It just moves it. Here's what each existing floor needs, how to check yours, and when to tear it out instead. Always read your product's installation instructions, since they list exactly what it can go over.

Can you install LVP over your existing floor? By floor type

These are general rules for floating click LVP. Glue-down LVP is pickier and usually needs a skim coat over tile, vinyl or wood so the adhesive bonds to a clean, smooth surface. See floating vs. glue-down LVP.

Can you install LVP over linoleum?

Yes, if the linoleum is a single layer, glued down everywhere, and flat. Walk the whole floor in socks and press on any seams. If you feel bubbles, soft spots or lifted edges, those spots need to be re-glued or cut out and patched with a cement-based floor patch. Linoleum itself is not cushioned, so it makes a good, firm base once it's sound.

The catch with old linoleum and sheet vinyl is what might be in it. See the asbestos section below before you scrape, sand or tear up any of it.

Can LVP be installed over tile?

Yes, and it's one of the most common requests we get. Tile is hard and stable, which LVP likes. Three things to check:

• Bond. Tap tiles with a screwdriver handle. A hollow sound means the tile has let go of the mortar. A few hollow tiles can be pulled and the holes filled. Lots of them means the floor is failing and should come out.
• Grout lines. Rigid-core LVP can span narrow grout lines. Many manufacturers say joints wider than about 1/4" or deeper than about 1/8" must be filled with a cement-based patch so they don't telegraph through or create soft spots under the locking joints. Thinner or flexible LVP may need every grout line filled. Check your product.
• Lippage and flatness. Tile edges that sit higher than the next tile have to be ground down. Then check the overall floor with a straightedge.

Can you put LVP over hardwood?

Usually, if the hardwood is nailed tight and flat. Cupped or crowned boards, loose boards and squeaks all need to be fixed first, since a floating floor won't hide them. Many installers run the new planks perpendicular to old strip flooring so the joints don't line up. If the hardwood is in good shape and worth saving, consider whether you really want to cover it. Floor refinishing isn't something we do, but it's worth a quote before you bury good oak.

Can LVP go over concrete?

Yes. Concrete is a great base if it's flat and dry. Test moisture first with a calcium chloride test (MVER) or in-situ RH probes (ASTM F2170), and compare to the limits in your product's instructions. Most floating LVP over concrete needs a 6 mil poly vapor barrier unless the plank's attached pad is rated as one. See LVP in basements and moisture.

Can you put LVP over carpet?

No. Not even low-pile commercial carpet. LVP needs a firm, flat base. On carpet the planks flex every time you step, and the locking joints break or separate. Carpet, pad, tack strip and staples all have to come out.

What you'll need

• 6 ft or 10 ft straightedge (or a long level) and a tape measure
• Screwdriver or small hammer for tap-testing tile
• Cement-based floor patch or embossing leveler and a flat trowel
• Floor scraper and shop vac
• Jamb saw (undercut saw) and a scrap plank with underlayment for a height guide
• Screws for loose hardwood or subfloor
• Moisture test kit for concrete
• Asbestos test kit or lab sample bag for older resilient floors
• Underlayment or vapor barrier as the LVP manufacturer specifies

How to prepare an existing floor for LVP: step by step

1. Identify the floor and count the layers. Pull a floor register or check at a doorway or threshold to see how many layers are already there. If there are already two or more, plan on tearing out.
2. Test for asbestos if the house is older. If you have sheet vinyl, linoleum or 9" x 9" tiles from before the 1980s, or black adhesive under any of it, get a sample tested by an accredited lab before you cut or scrape anything.
3. Check that it's solidly attached. Walk every inch. Tap tile. Press on vinyl seams. Listen for squeaks in wood. Fix or remove anything loose.
4. Check flatness. Lay the straightedge in several directions. Most LVP calls for about 3/16" in 10 ft, some 1/8" in 6 ft. Mark high spots for grinding and low spots for patch. More in what subfloor leveling is.
5. Fill grout lines and low spots. Trowel cement-based patch into wide or deep grout joints and dips, feathering it flush. Let it cure per the bag before installing.
6. Clean it. Scrape off old wax, paint drips and debris, then vacuum. Grit under a floating floor causes clicking and wear at the joints.
7. Measure height at every door and appliance. Lay a scrap of the new plank with its underlayment on the old floor and check the door swing, the dishwasher opening and the step to the next room.
8. Undercut door casings and jambs. Use the scrap plank as a guide and cut the casing with a jamb saw so the new floor slides under it. Trim doors that will rub.
9. Lay the underlayment or vapor barrier. Only what the manufacturer specifies. Don't add foam under a plank that has an attached pad unless the instructions allow it.
10. Install, leaving the expansion gap. Typically about 1/4" to 3/8" at walls and fixed objects. Don't pin the floor under cabinets or heavy built-ins. Step-by-step install in how to install LVP flooring.

How much height does LVP add, and what does it affect?

Most LVP plus underlayment adds somewhere around 1/4" to 3/8" (check your product's total thickness). That small number causes problems in specific spots:

• Doors. Interior doors may need trimming. Exterior doors and storm doors may need threshold work.
• Dishwasher. If the new floor runs into the dishwasher opening, the dishwasher may not fit back under the countertop or come out later for service. Measure the opening before you start. Often the fix is lowering the dishwasher legs or stopping the new floor at the front of the opening with a level shim behind.
• Refrigerator. Check clearance under upper cabinets or a built-in surround.
• Range and slide-in appliances. Make sure the top still lines up with the countertop.
• Toilets. The flange should sit on top of the finished floor. Raise it with a flange extender or spacer kit if needed.
• Transitions and stairs. A bigger step at the doorway to the next room, and an uneven first or last stair riser. See flooring transitions and uneven floor heights between rooms.

Asbestos in old vinyl, linoleum and black mastic

Many older resilient floors, including some sheet vinyl, linoleum backings and 9" x 9" floor tiles, along with the black "cutback" adhesive often found under them, can contain asbestos. This is common in homes built before the 1980s. Intact and undisturbed, it is generally considered low risk. Sanding, scraping, grinding or tearing it up is what can release fibers.

You have two options:

• Encapsulate. Leave it in place and cover it. A floating LVP floor over intact old flooring doesn't disturb it, which is one good reason to go over instead of tearing out. Don't grind or sand the old surface to flatten it. Use patch to fill low spots instead.
• Remove. If the floor has to come out, have it tested first. If it contains asbestos, removal should be done by a licensed abatement contractor following state rules. Requirements vary by state, so check with the state health or environmental agency in Connecticut, Massachusetts or Rhode Island.

In pre-1978 homes, also be careful pulling or cutting old painted baseboard and door casing. The paint may contain lead. Test it or have a certified pro handle it.

Common mistakes to avoid

• Going over carpet, cushioned vinyl or a floating floor.
• Skipping the flatness check because the old floor "looks fine."
• Leaving deep grout lines unfilled, which leads to clicking joints and visible lines.
• Forgetting the dishwasher until it won't go back in.
• Sanding or scraping old vinyl or black mastic without testing it.
• Stacking a second pad under a plank with an attached pad.
• Pinning the floating floor under cabinets, an island or heavy trim.

When to tear out instead

• The old floor is loose, cracked, hollow or damaged in more than a few spots.
• There are already two or more layers.
• The added height causes real trouble at exterior doors, cabinets or stairs.
• There's a moisture problem, soft subfloor or rot you need to see and fix.
• It's carpet or a floating floor.

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.

When to hire a pro

Call someone if the house is older and you aren't sure what the existing floor is, if the floor needs significant leveling, if there's tile with lots of hollow spots, or if the kitchen has tight appliance clearances. Those are the jobs where a mistake shows up months later. Our prep checklist covers what to do before any install.
