Terrazzo Floor Restoration in Washington, DC
Family owned since · projects completed · Diamond grinding, polishing & sealing.
Washington, DC has more terrazzo underfoot than almost any city in the country. It's in the lobbies of Federal buildings and Dupont Circle apartment houses, in the vestibules of Georgetown and Capitol Hill rowhomes, and in the corridors of schools, hospitals, and hotels across the District. When it's cared for, terrazzo is the most durable decorative floor ever made. When it's neglected, it goes dull, gray, and stained — and most owners assume it's beyond saving. It almost never is.
Purcell's Flooring restores terrazzo across DC — grinding out decades of wear, repairing cracks and missing aggregate, and polishing the surface back to a mirror finish. Whether you have a small original vestibule in a historic rowhome or 20,000 square feet of commercial lobby, the process is the same craft at different scale. Every project starts with a free on-site consultation: we look at your actual floor, test a small area where appropriate, and give you an honest, itemized number.
Cost of Terrazzo Restoration in Washington, DC
Terrazzo restoration pricing depends on the floor's condition, the level of finish you want, square footage, and how much crack or aggregate repair is needed. Below are typical Washington, DC ranges. Every quote is free, on-site, and itemized — no surprises.
| Service | Typical Cost | Notes |
|---|---|---|
| Hone & Polish (no grinding) | $3.00 – $6.00 / sq ft | Best for floors that are sound but dull. Restores sheen and clarity without removing material. |
| Full Diamond Grind, Polish & Seal | $5.00 – $12.00 / sq ft | Complete restoration — flattens, removes deep wear and stains, exposes fresh aggregate, polishes and seals. Most common for neglected floors. |
| Crack & Chip Repair | From $20 / linear ft | Color-matched epoxy or cementitious fill with re-grind to blend. Quoted per area after inspection. |
| Penetrating Sealer / Impregnator | $0.75 – $1.50 / sq ft add-on | Protects against staining in entries, kitchens, and high-traffic commercial areas. |
| Commercial / Large-Area (5,000+ sq ft) | $4.00 – $8.00 / sq ft | Lobbies, schools, hotels, hospitals. Lower per-sq-ft rate at scale; can be phased or done after hours. |
Ranges include materials and standard labor. Heavy staining, extensive crack repair, removing old coatings or epoxy overlays, and matching original aggregate can add to the total. Get your exact number with a free on-site consultation.
The terrazzo restoration process
Terrazzo is a composite of marble, granite, glass, or other aggregate set in a cement or epoxy matrix, then ground and polished flat. Restoring it is a mechanical process — there's no "mop-on shine" shortcut that lasts. Done correctly, the result holds up for decades; done with the wrong abrasives or in too few steps, the floor hazes over within months. Our crew follows a documented multi-step process on every job, from a Kalorama rowhouse entry to a downtown DC office lobby.
- Free on-site consultation: assess the matrix type, aggregate, cracks, prior coatings, and finish goal
- Deep clean and strip any old wax, acrylic, or topical coatings hiding the stone
- Crack, chip, and spall repair with color-matched fill, plus aggregate replacement where needed
- Progressive diamond grinding — coarse to fine — to flatten the surface and remove wear
- Honing through successively finer grits to develop clarity and depth
- Polishing to your chosen sheen, from a soft satin honed look to a full reflective gloss
- Penetrating sealer / impregnator to resist staining without a plastic film
- Final walk-through and care instructions to protect your investment
Terrazzo's biggest advantage is that the decorative aggregate runs through the full thickness of the topping. That's why a floor can be ground and re-polished many times across its life — and why an original 1920s terrazzo vestibule in a DC rowhome can look brand new again a century later. The National Terrazzo & Mosaic Association documents terrazzo systems that have remained in service for 75+ years with periodic restoration.
Restoration, repair, refinishing & sealing
"Terrazzo restoration," "refinishing," "repair," and "polishing" often describe parts of the same job. Here's what each typically means so you know what you're paying for.
Terrazzo restoration & refinishing
The full process above — grinding, honing, and polishing a worn or dull floor back to a fresh finish. This is what most DC homeowners and property managers mean when they search for "terrazzo floor restoration" or "terrazzo refinishing." It's the right call when the surface is gray, scratched, etched, or has lost its shine.
Terrazzo repair
Targeted fixes for cracks, chips, spalls, and missing aggregate — often after settlement, water intrusion, or a removed wall or fixture. We color-match the matrix and aggregate so repairs blend into the field, then grind the patch flush. Repairs are frequently combined with a full refinish so the whole floor reads as one surface again. If moisture is the underlying cause, see our water-damaged floor repair service.
Terrazzo sealing
Terrazzo is porous, especially older cement-matrix floors. A penetrating impregnating sealer soaks in and resists oil and water staining without leaving a slippery topical film. We recommend sealing after every restoration and periodic re-sealing in high-traffic entries — exactly the kind of practice the Natural Stone Institute recommends for natural-stone-aggregate surfaces.
Marble & natural stone restoration
The same diamond grinding and polishing craft restores marble thresholds, treads, and stone floors common in DC's older buildings. If you have marble or other natural stone alongside your terrazzo, we can restore both in one visit.
Commercial & historic terrazzo in Washington, DC
DC is a terrazzo town because of its building stock. Mid-century institutional construction used terrazzo heavily for its durability, and the District's historic rowhomes used decorative terrazzo and mosaic in entries and vestibules. That means our work splits between two worlds.
Commercial & institutional: hotel lobbies, office buildings, schools, hospitals, museums, transit and government facilities. These floors take enormous foot traffic and need restoration that's scheduled around operations — phased by section, done overnight, or completed over a weekend so the space reopens on time. We're , and we coordinate with facility managers and GCs on access, dust control, and cure times.
Historic & residential: original terrazzo and mosaic vestibules and entry halls in Georgetown, Capitol Hill, Dupont Circle, and Logan Circle rowhomes. These restorations are about preserving original material, not replacing it. For homes in historic districts, the DC Preservation League's homeowner guides are a useful starting point on what's expected when working on protected properties — and preserving original terrazzo is almost always viewed favorably.

Frequently asked questions
How much does terrazzo floor restoration cost in Washington, DC?
Full diamond grinding, polishing, and sealing typically runs $5–$12 per square foot in DC; a lighter hone-and-polish runs $3–$6. Crack and aggregate repair is quoted per area. Large commercial floors price toward the lower end per square foot because of scale. Every consultation and quote is free and itemized.
Can dull, stained, or cracked terrazzo really be restored?
Almost always, yes. Because the aggregate runs through the full thickness of the topping, terrazzo can be ground and re-polished many times. Decades of dullness, etching, staining, and cracks can be ground out, repaired, and polished back to a mirror finish — which is why century-old DC terrazzo is still in service today. Replacement is rarely necessary.
How long does a terrazzo restoration take?
A residential vestibule or entry hall is often a one-day job. A typical commercial lobby runs two to four days depending on square footage, repair scope, and finish level. Large institutional floors are scheduled in phases or after hours so your space keeps operating. We give you a firm timeline at the free on-site consultation.
Do you seal terrazzo after restoring it?
Yes — we finish every restoration with a penetrating impregnating sealer that resists oil and water staining without a slippery topical film. In high-traffic entries and commercial spaces we recommend periodic re-sealing, which we can handle on a maintenance schedule.
