Terrazzo Grinding, Polishing & Sealing Services

Terrazzo restoration in Chicago brings back the floors that made the city's mid-century buildings, schools and vintage apartment lobbies famous. Terrazzo floor restoration in Chicago starts by stripping decades of wax and topical coatings, then grinding with metal-bond diamonds to remove scratches, stains and unevenness and expose fresh marble chips. Terrazzo polishing in Chicago continues through progressively finer resin diamonds until the floor reaches a satin or high-gloss finish with real depth. Terrazzo cleaning in Chicago is then simple: neutral cleaner and periodic maintenance instead of endless waxing. We repair cracks, holes and divider-strip damage before polishing and finish with a penetrating sealer.

Commercial & Residential Terrazzo Restoration

Building owners and property managers use our terrazzo restoration in Chicago for lobbies, corridors, stairwells, schools, churches and municipal buildings where a high-gloss finish signals a well-kept property and eliminates the cost of stripping and waxing. Commercial terrazzo floor restoration in Chicago is scheduled overnight or in phases so entrances stay open. Homeowners bring us vintage terrazzo in condos, bungalow foyers, sunrooms and bathrooms that has been hidden under carpet or dulled by years of wax. Terrazzo polishing in Chicago homes is done wet and dust-free. Every project is quoted from photos or a site visit, with a written scope and a maintenance plan.

Common questions about terrazzo restoration

Can you bring old terrazzo back to a high-gloss shine?

Yes. Terrazzo is essentially marble chips in a cement or epoxy matrix, so it polishes the way marble does. Grinding removes the worn surface and old coatings, and diamond polishing builds a genuine high-gloss finish from the stone itself rather than a wax layer that dulls within months.

Do you repair cracks and holes in terrazzo floors?

Yes. Cracks are stabilized and filled, holes and divots are patched with matching aggregate and matrix, and missing chips are replaced before the floor is ground so repairs blend in. Damaged or lifting brass divider strips are re-set. Repairs are part of every terrazzo floor restoration in Chicago we perform.

How often should terrazzo be professionally restored?

A properly ground and polished terrazzo floor typically holds its finish for many years with neutral cleaning. Busy commercial lobbies benefit from a light re-polish every one to three years, while residential floors go far longer. Terrazzo cleaning in Chicago with the right products avoids the need for frequent full restoration.

Can old terrazzo under carpet or tile be restored?

Almost always. Once the covering and adhesive are removed we grind the floor flat, fill cracks and divots with color-matched material, then hone and polish it back to a reflective finish. Vintage terrazzo often looks better than new.

How do you repair cracks in terrazzo?

Cracks are cleaned out, filled with a tinted epoxy or cement fill that matches the surrounding matrix and aggregate, and ground flush before the floor is polished. Structural cracks may be pinned first to keep them from reopening.

Is polished terrazzo slippery?

A properly diamond-polished terrazzo floor without topical wax meets standard slip-resistance guidelines when dry. We can also apply an anti-slip treatment in entries and commercial lobbies if requested.
