“We hired Rose Restoration to "clean up" a marble tile foyer area. Never having had marble flooring before, we had lots of questions. Justin was very knowledgeable and explained everything very patiently — honed vs polished finish, hairline cracks and what to do about them, sealer and continuing maintenance.”

Project: Carrara marble floor restoration in a historic Georgetown row home — diamond honing and re-polishing of approximately 380 square feet of foyer, hallway, and powder room Carrara that had accumulated 15 years of foot traffic wear, scratches, and lippage at tile transitions. 3-day restoration; whole-home stone refinish completed without removing any tile.
The project at a glance
- Location: Georgetown, Washington DC
- Stone: Carrara marble, 12×24 polished tiles laid in 2010
- Surface: Foyer (90 sf), main hallway (210 sf), powder room (40 sf), entry vestibule (40 sf)
- Age of installation: 15 years
- Damage: Generalized dulling, 30+ visible scratches, lippage at 12 tile transitions, dirt embedded in grout, two cracked tiles near the entry
- Project span: 3 days
- Crew: 3 technicians (1 senior + 2 mid-level)
The damage we found
The homeowner had purchased the row home two years earlier and finally decided the floors needed serious attention before hosting a holiday gathering. Fifteen years of urban Georgetown foot traffic had left visible damage:
- Generalized surface dulling: The original polish was almost completely gone in the highest-traffic lanes — the foyer center, the hallway path, and around the powder room threshold. The remaining polish around tile edges and corners made the wear pattern especially visible.
- Scratches: Most scratches were superficial — gravel and grit dragged in from the brick sidewalks Georgetown is known for. A few deeper scratches likely came from furniture moves over the years.
- Lippage at tile transitions: Twelve tile-to-tile transitions had developed visible height differences (roughly 1-2 mm). This is common when a building settles unevenly — Georgetown row homes are old, and the substrate moves over decades.
- Embedded grout dirt: The original light-grey grout had darkened to nearly black in the foot-traffic lanes from accumulated dirt, mop water, and shoe polish residue.
- Cracked tiles: Two tiles near the entry had cracked — one from a dropped object, one from substrate stress at the transition between vestibule and foyer.
The restoration process
- Site protection. Stair runners removed, antique furniture relocated to one bedroom, plastic walls erected at the kitchen and main staircase to contain dust and slurry. The homeowner’s two cats were boarded for the duration.
- Crack repair. The two cracked tiles were addressed first with color-matched epoxy filler and re-polished after curing. The repairs are visible only on close inspection — typical for Carrara crack repair on patterned stone.
- Lippage flattening. Started with 50-grit metal-bond diamond pads to flatten the worst tile-to-tile lippage. This is the most aggressive step but also the most transformative — the entire floor reads as one continuous surface afterward.
- Diamond honing — coarse to medium. Progressed through 100, 200, and 400 grit resin-bond pads to remove the metal-bond scratches and the original surface damage simultaneously.
- Diamond honing — fine. Refining passes at 800, 1500, and 3000 grit. By the end of the 3000 pass, the surface had a satin appearance.
- Polishing. Final polishing with chemical polishing compound applied via weighted polishing machine. Carrara polish takes patience — the white-grey background has lower light reflectivity than Calacatta, so the polish is more about clarity than mirror brightness.
- Grout deep clean and re-color. Existing grout cleaned with alkaline grout cleaner and high-pressure extraction, then re-colored with a penetrating grout colorant in the original light grey.
- Sealing. Premium impregnating sealer applied across the entire restored area. Carrara is more porous than Calacatta and benefits significantly from sealing — especially in entry areas where deicing salt residue gets tracked in during winter.
The outcome
By the end of the 3-day project, the entire ground floor read as new construction:
- Generalized dulling fully restored — uniform polish from foyer through the entire hallway
- All visible scratches removed
- Lippage eliminated; no more catching of cleaning equipment or tripping hazards
- Grout returned to its original light-grey color
- Cracked tiles repaired and re-polished — invisible from standing height
- Entire surface sealed against future foot-traffic damage
The homeowner hosted the holiday gathering ten days later and the floors were the talking point of the evening. She has us back annually for a maintenance polish on the entry foyer only (the highest-wear zone) — the hallway and powder room have held up beautifully without intervention.
Why this project matters for similar Carrara installations
Three takeaways for homeowners with older Carrara floors:
- Carrara dulls faster than Calacatta in foot-traffic areas. The grey-veined background is more porous and softer. If you have Carrara in a high-traffic foyer or hallway, expect to need restoration every 6-10 years.
- Lippage flattening is what makes a 15-year-old floor look new. Even more than the polish itself, removing the height differences between tiles is what transforms the visual impression. Without lippage flattening, the floor still reads as worn even after polishing.
- Don’t replace cracked tiles unless you have to. Color-matched epoxy repair on Carrara is excellent — the variegated pattern hides the repair. Replacement tiles from the original lot are usually impossible to find for a 15-year-old install.
Cost range for similar projects
- Carrara floor restoration (200-400 sf): $2,800–$5,500
- Lippage flattening surcharge (when tile transitions are uneven): $400–$900 added to base
- Crack repair (per tile): $150–$300
- Grout deep clean and re-color (per project): $400–$800
This particular project (380 sf with lippage and 2 crack repairs) came in at the upper end of the typical range.

Frequently asked questions
Can a Carrara floor that looks this worn really be restored, or do I need to replace it?
Almost always restored. Even badly worn 15-20 year-old Carrara floors respond well to diamond honing as long as the structural condition is sound. Replacement is only required when there is significant substrate failure or majority tile damage.
Do you have to remove the tile to fix the lippage?
No. Diamond honing flattens lippage in place. The amount of stone removed from the high tile is microscopic — typically less than 1mm — well within the depth of the original tile.
How long can I expect the restored floor to last before needing service again?
For a Georgetown foyer with normal foot traffic, expect 6-10 years before the polish dulls visibly again. Hallways and powder rooms typically hold up 10-15 years. We recommend annual sealer refresh in the entry zones.
Will the grout color match the rest of my home’s grout?
The re-colored grout will look very close to the original color. We can also tone it darker or lighter to match adjacent areas if needed.
What about the cracked tiles — will the repairs be visible?
From standing height, the repairs are invisible to a normal observer. From very close inspection (kneeling, looking at floor level), the repairs are subtly visible — typical for any color-matched stone crack repair.
How much disruption should I expect during the 3 days?
Significant. We seal off the work area with plastic walls, which means restricted access to parts of your home. We provide an end-of-day staging plan so you can use bedrooms and bathrooms without crossing the work zones. Most clients stay in the home; some prefer to stay elsewhere for the duration.
