Polished concrete floors in Miami

Grinding and polishing the slab inside the house, usually after the tile comes up

Polished concrete looks great in photos, and some owners still end up regretting it: the floor is very hard on feet, knees and hips, a concrete house can get loud and echoey, and the slab under your tile may not look like the photos at all. Know all three before the tile comes up. Call (786) 686-1048 and we'll connect you with an independent concrete polishing contractor serving your part of Miami-Dade. Ask them to grind a test patch so you see your own slab, explain what patches and cracks will show, and say whether you're getting a real polish or a grind and seal.

Know this going in

  • "Polishing does not hide an old garage floor, it exposes it."Old patches, cracks and plumbing cuts stay visible.
  • "Concrete dust EVERYWHERE."Ask how they contain dust and protect the rest of the house.
  • "Save some money and just seal the floors."Grind and seal costs less, but scratches and wears faster.

What people ran into

"Sent us a bill for $2,955 to cover the additional prep work"

The tile came up in patches and left a cratered surface, and the price went up. Nobody knows what a slab looks like until the floor covering is off, so ask how extra prep is priced before work starts, per square foot, in writing.

"They didn't cover anything like they said they would"

Grinding a slab inside a lived-in house makes dust. One couple came home to dust everywhere and the toilets still off. Ask about dust extraction, plastic walls, who removes and resets the toilets and baseboards, and what "clean" means at the end.

"The dog is leaving marks on a 2 months old polished floor"

A true polish is the concrete itself, ground and densified. Marks that show up fast often mean a topical coating was put on top. Find out which one you're paying for.

The honest downsides

"Very hard on the feet, hips and back"

A concrete floor doesn't give. People who stand a lot at home, or have sore joints, notice it, and rooms with hard floors and bare walls get loud. Rugs where you stand and sit, and soft furnishings, help. If that's a deal-breaker, polished concrete may not be the right floor, and that's worth knowing now.

Eleven of the 102 stories we read were about this, tied for the most common complaint.

"Most of them are cowboys"

Polishing takes heavy grinders and a sequence of finer and finer diamonds. Ask how many passes, what grits, whether they densify the slab, and to see a floor they did a year or more ago.

Another eleven were about a crew that didn't really know polishing.

"Concrete dust EVERYWHERE"

Ask about the grinder's vacuum, plastic barriers, and what they'll move, remove and put back. Get it in the scope.

And eleven more were about the mess left behind.

What polishing costs

No Florida prices turned up in our research, so we won't post a Miami number as fact. One poster summed up the general split as "$6 to $9 a foot for a true polish and $3 to $6 for grind and seal", from outside Florida. Your contractor quotes after a test grind.

What moves the number: tile, glue and thinset removal, filling cracks and patches, how glossy you want it, densifier and guard, and how much furniture and fixtures have to move.

Telling a good polisher from a cowboy

  • A test patch so you see your slab before you commit.
  • A written price for extra prep if the slab is worse than expected.
  • Polish or grind and seal, named clearly on the quote.
  • Dust control and what gets moved and reset.
  • A finished floor you can go and stand on.

Miami homes: tile, terrazzo and slabs

A lot of South Florida homes from the 1950s to the 1970s have terrazzo under the tile or carpet, and many others have a plain slab with years of patches. A test patch tells you which you have; terrazzo usually means restoring the terrazzo rather than polishing concrete. Kitchen tile often runs under the cabinets, so the floor may stop at the cabinet line. Plumbing trenches cut during old remodels show as lines in the finished floor.

Miami's warmth works in polished concrete's favor: a cool, hard floor feels better here than in a cold climate. The noise and the hardness underfoot don't change.

Polished concrete questions

Are there hidden costs involved with polished concrete floors?

The common one is extra prep after the tile comes up: glue, thinset, deep patches and cracks. Get that priced per square foot in the quote, so it isn't a surprise.

Can cracks in polished concrete be repaired so they don't show?

They can be filled and polished over, but the repair usually still shows a little. Many people treat cracks as part of the look.

Should we save some money and just seal the floors, or have them polished?

Grind and seal costs less up front but the coating scratches and needs redoing. A true polish costs more and wears better. With pets or heavy use, the polish usually wins.

Is polished concrete a good idea in a house?

It's durable, easy to clean and suits Miami's heat. It's also hard underfoot and can make rooms loud. If either matters a lot to you, plan rugs, or choose another floor.
