Flooring Over Existing Tile vs. Tearing It Out in a Florida Home

Almost every home we walk into around The Villages and Wildwood has tile somewhere — often wall to wall through the entry, kitchen, baths and hallways, set straight onto the slab sometime in the last thirty years. When homeowners are ready for something new, the first question is usually some version of: can you just go over it?

Sometimes, yes. Going over sound tile is a real option, and we do it. But the thing that decides it is almost never how the tile looks. It's whether the tile is still bonded to the slab, and how much height the room can afford to give up.

Start by Tapping the Floor

Walk the room and tap the tile with your knuckle or a coin. Most of it will sound solid and dull. Some of it may sound hollow, like there's air under it.

That hollow sound means the thinset has released from the slab in that spot. The tile is still held in place by its grout and its neighbors, but it isn't attached anymore. Anything installed on top of a loose tile moves when that tile moves, and a floating floor will flex and click over that void every single time someone walks across it.

A few hollow tiles in a corner can be pulled and reset. Hollow sounds scattered across a whole room mean the floor is coming out. That's not a judgment call about the old tile — it's about having something solid to build on.

The Other Half of It: Height

This is the part homeowners rarely think about, and in Central Florida it's usually what makes the decision for us.

Leaving the tile and adding a new floor on top raises the finished floor. That new height has to go somewhere, and in a Florida home there are specific places it runs out of room:

• The slider to the lanai. Most of these homes have a deliberate step down at the slider so blowing rain runs out instead of in. Raising the interior floor shrinks that step. We won't trade a dry threshold for saved demo work.
• Exterior and garage doors. Doors can be trimmed, but a threshold that's already tight on a slab-on-grade house doesn't have much to give.
• Bathrooms. A toilet flange and a shower curb are set to one floor height. Raise the floor and the flange needs an extender and the curb has to be looked at.
• Cabinets and appliances. A dishwasher sits in a fixed opening. Raise the floor under it and it may not come back out for service.

If a plan works everywhere except the lanai slider, we'll often tear out there and go over the tile in the interior rooms. Two approaches in one house is normal.

When Going Over the Tile Works Well

Rigid-core luxury vinyl plank is the material that makes this possible most often. It floats rather than bonding to what's underneath, it's dimensionally stable through Florida's humidity swings, and it tolerates a hard, flat base like bonded tile very well.

The best candidates are large-format tile with narrow grout joints, flat and fully bonded. The joints are shallow enough that the plank doesn't notice them, and nothing has to be ground off the slab.

There's a quiet advantage too: a bonded tile floor and its thinset are themselves a slow path for moisture. Leaving that intact means we aren't opening up bare slab in a climate where the water table sits close. We still test the slab either way, but an undisturbed tile floor is a reasonable starting point.

When We Take It Out Instead

Wide or deep grout joints are the common dealbreaker, especially on older small-format tile. A thin plank bridging a wide joint has nothing supporting it right there, and over a season of foot traffic that's where you feel the give.

Lippage — tile edges sitting at different heights — is the same problem. A floating floor telegraphs it, and a tile floor can't be flattened the way a slab can.

Nail-down hardwood isn't an option over tile at all. If that's the floor you want, the tile comes out.

A crack running through the tile in a straight line usually means the slab moved underneath. That gets looked at properly before anything new goes down.

And if the room is part of a shower or bath remodel, the tile is coming up anyway, so going over it saves nothing.

What Tear-Out Actually Means

We'd rather you hear this from us than discover it on day two. Removing tile that's well bonded to a slab is the loudest, dustiest part of any flooring job. It also doesn't end when the tile is gone: the thinset ridges left behind have to be ground down, and a slab that's been under tile for decades is rarely as flat as the tile made it look. Some of these floors need leveling compound before a new plank or tile floor goes down.

None of that is a reason to avoid tear-out when the floor needs it. It's a reason to know which path you're on before the work starts.

Settle These Before Install Day

• Where does the new floor have to meet the lanai slider, the front door and the garage step?
• Did the tile sound hollow anywhere when you tapped it?
• Are grout joints narrow and flush, or wide and worn down?
• Is a bathroom or shower part of the project?
• Do you want nail-down hardwood, or is a floating floor fine?

Most of these we can answer standing in your house in twenty minutes.
