Terrazzo Floor Restoration & Polishing in Miami
Terrazzo doesn't wear out — it gets buried. Under decades of janitorial wax, under a sealer that ambered, under carpet glued down in the 1980s. Strip that away, repair the damage, and progressively polish the stone underneath, and the original floor comes back. A properly installed terrazzo floor is built to last the life of the building — commonly 75 to 100 years (National Terrazzo & Mosaic Association).

What terrazzo restoration covers
From a single lobby to a whole building. Each piece links to the service behind it.
Progressive diamond steps that erase scratch haze and rebuild depth and reflection — no coating involved.
Details Buildup & coating removalDecades of wax, sealer, or carpet adhesive stripped off to expose the original terrazzo underneath.
Details Chip & crack repairDamage filled and colour-matched to the existing aggregate so the finished surface reads continuous.
Details Sealing & protectionPenetrating sealer closes the pores so the restored surface resists staining and cleans easily.
Details Floor assessmentAn honest read on what you have and whether restoration is the right call — before any money is spent.
Details Maintenance polishingA scheduled shine program that keeps a restored floor restored instead of letting it slide back.
DetailsMost floors get replaced. Terrazzo gets refinished.
That's the whole economic argument, and it's why a replacement quote and a restoration quote are usually not close. Terrazzo is a solid, ground composite — not a thin wear layer that can be used up. Restoration removes a whisker of the surface to reveal fresh terrazzo beneath, which is why the same floor can be renewed again and again across a century of service.
A properly installed terrazzo floor is built to last the life of the building — commonly 75 to 100 years, needing only chip repairs, occasional resealing, and routine maintenance.
National Terrazzo & Mosaic AssociationThe other advantage is what happens after. Because the shine is the polished stone rather than a topical coating, it doesn't peel, yellow, or need re-coating on a cycle — so the long-run maintenance curve bends the opposite way from a waxed floor. Our guide to whether a 30-year-old terrazzo floor can really be saved covers how to identify what you have before you call anyone.
How terrazzo restoration actually works
Six defined steps. The order matters — polishing a floor that still has adhesive on it accomplishes nothing but wasting diamonds.
| Step | Target | What happens |
|---|---|---|
| 1 · Assess | Before anything | Identify the floor, check topping thickness, test a small area, and confirm restoration is worth doing. |
| 2 · Strip the buildup | Wax, sealer, adhesive | Remove decades of topical finish and carpet glue to expose the actual terrazzo. |
| 3 · Grind & hone | Coarse to medium grit | Flatten, remove deep scratching, and level the surface across the field. |
| 4 · Repair | Chips, cracks, holes | Fill and colour-match to the existing aggregate so repairs disappear into the pattern. |
| 5 · Polish | Fine to finish grit | Successive diamond passes rebuild clarity and reflection — the shine is the stone itself. |
| 6 · Seal | Penetrating sealer | Close the pores against staining and hand the floor back easier to maintain than it was. |
Floors that only need the finishing work run through marble & stone polishing; heavier grinding and adhesive removal go through floor deep restoration, and a restored floor stays restored on a scheduled shine program.
South Florida is sitting on hidden terrazzo.
Mid-century and MiMo-era buildings across Miami-Dade and Broward were poured with terrazzo as standard, and an enormous share of it is still there — under carpet glued down decades ago, or dulled by years of janitorial wax. In roughly half the older buildings we walk, the "old tile floor" an owner wants to replace turns out to be original terrazzo waiting to be uncovered.
If you want to check before calling anyone: look for no grout lines and irregular stone chips in a pattern that never repeats. Then find a spot the original floor was never covered — inside a utility closet, under a raised counter, behind a built-in. That's what your floor looked like when it was new.
Found aggregate under a carpet corner? Stop pulling. Adhesive removal is the delicate step, and enthusiastic scraping is one of the few ways to genuinely damage a terrazzo surface.
Terrazzo restoration across Miami-Dade & Broward
We restore terrazzo throughout South Florida — lobbies and corridors in Miami and Aventura, institutional and municipal floors in Hialeah and Coral Gables, and buildings up through Fort Lauderdale and Broward.
What building owners ask us.
Can old terrazzo be restored?
Almost always. The dullness is rarely worn-out stone — it is usually decades of wax, coating, or carpet adhesive sitting on top of a floor that is structurally fine. Because terrazzo is a solid ground composite rather than a thin surface layer, restoration works by removing a whisker of the surface to reveal fresh terrazzo underneath, which is why it can be renewed repeatedly. A properly installed terrazzo floor is built to last the life of the building — commonly 75 to 100 years, per the National Terrazzo & Mosaic Association.
How much does terrazzo floor restoration cost?
It is priced by square footage and condition — how much buildup has to come off, how many chips or cracks need repair, and the level of polish you want. It is almost always a fraction of the cost of tearing out and replacing the floor, which is the main reason restoration wins. We quote a written number after a walkthrough that measures the actual floor and tests a small area first.
What is the difference between terrazzo polishing and terrazzo restoration?
Polishing is the finishing work on a floor that is already sound — progressive diamond passes that rebuild clarity and reflection. Restoration is the full process: stripping buildup or adhesive, grinding and honing, repairing chips and cracks, then polishing and sealing. A floor that has only lost its shine needs polishing. A floor that has been carpeted, waxed for decades, or damaged needs restoration.
Can terrazzo that was covered with carpet be saved?
Yes, and it is one of the most dramatic reveals in floor work. Carpet adhesive hides terrazzo, it does not destroy it. The adhesive removal is the delicate part and is where DIY attempts cause real damage — aggressive scraping can gouge the surface. If you find aggregate under a carpet corner, stop pulling and get an assessment.
How long does restored terrazzo stay looking good?
With entry matting and routine maintenance, one to three years between polish cycles depending on traffic — and a scheduled maintenance program keeps it there indefinitely. Because the shine is the polished stone rather than a topical coating, it will not peel or yellow. The one thing to avoid afterward is putting wax back on it, which recreates the exact problem that took decades to undo.
When is terrazzo not worth restoring?
A small number of floors are past it — where the terrazzo topping has been ground too thin across many previous refinishes, or where structural movement has caused widespread cracking that repair cannot reconcile. That is what the assessment is for. In the large majority of cases the answer is the happy one, and we will tell you plainly if yours is the exception.
