Terrazzo cracks typically result from building settlement, substrate movement, or expansion joint failure. We repair cracks by routing them out, filling with color-matched epoxy resin mixed with matching aggregate chips, then grinding and polishing flush with the surrounding floor. The repair is virtually invisible and structurally sound.
When terrazzo chips lose aggregate, the exposed cement matrix deteriorates quickly. We patch damaged areas by carefully matching the original aggregate size, color, and density. The patched area is ground level with the existing floor and polished to match the surrounding finish.
Terrazzo can absorb stains from spills, cleaning chemicals, and years of foot traffic. Oil-based stains, rust, and organic discoloration require different treatment approaches. Professional deep cleaning and diamond honing remove surface-level staining, while deep stains may require poultice treatment before refinishing.
Years of foot traffic, improper cleaning products, and wax buildup turn terrazzo floors dull and hazy. The original shine is buried under layers of damage. Our diamond grinding and polishing process strips away the damaged surface and restores the natural luster of the aggregate and binder. No coatings or waxes are needed — the shine comes from the stone itself.
The brass, zinc, or aluminum divider strips in terrazzo floors can become loose, bent, or corroded over time. We repair or replace divider strips to restore the floor's structural integrity and visual pattern. Proper divider strip maintenance prevents crack propagation between terrazzo sections.
Every terrazzo restoration follows a systematic process tailored to the condition of the floor:
Terrazzo restoration costs depend on the floor's condition, size, and accessibility:
| Service | Cost Range |
|---|---|
| Basic cleaning and polishing | $3 – $8 per sq ft |
| Full grinding, honing, and polishing | $8 – $18 per sq ft |
| Crack and chip repair (per repair) | $250 – $750 |
| Full restoration (heavy damage) | $15 – $25 per sq ft |
In all cases, terrazzo restoration costs a fraction of replacement. Replacing terrazzo can run $25–$75 per square foot plus demolition and downtime. Restoration preserves the original floor — often a historically significant asset — at 50–70% less cost.
Terrazzo repair costs depend on the extent of damage. Individual crack or chip repairs run $250–$750 each. Full floor restoration with grinding and polishing ranges from $8–$18 per square foot. A typical 2,000 sq ft commercial lobby restoration runs $16,000–$36,000 — compared to $50,000–$150,000 for replacement.
Yes. Cracks are routed out, filled with color-matched epoxy resin mixed with matching aggregate chips, then ground flush and polished to match the surrounding floor. The repair is virtually invisible. We also address the underlying cause — whether settlement, substrate failure, or expansion joint issues — to prevent recurrence.
Timeline depends on floor size and condition. A 500 sq ft residential entry can be completed in 1–2 days. A 5,000 sq ft commercial lobby typically takes 5–10 days. For occupied buildings, we schedule work during nights and weekends to minimize disruption. The floor is typically walkable within hours of sealing.
Almost always yes. Terrazzo is one of the most durable flooring materials ever created — many floors from the 1920s–1960s are still structurally sound beneath decades of wax, dirt, and neglect. Professional restoration reveals the original beauty at a fraction of replacement cost. Terrazzo floors that look destroyed are often just 2–3 days of grinding away from looking new.
Yes. Traditional cement-based terrazzo (common in older buildings) and modern epoxy terrazzo require different grinding and polishing approaches. Our team has experience with both systems, as well as rustic and Venetian terrazzo styles. We assess the binder type during our initial inspection and tailor our process accordingly.
Terrazzo is most common in schools, hospitals, government buildings, churches, airports, courthouses, and mid-century commercial buildings. Many historic buildings in Washington DC, Virginia, and Maryland feature original terrazzo floors from the 1930s–1970s. Rose Restoration has restored terrazzo in schools, government facilities, hospitals, churches, and commercial lobbies across the DC metropolitan area.
