You’re looking at marble that’s lost its shine. Maybe it’s dull from decades of foot traffic, or scratched from furniture moves, or stained from Long Island’s hard water. The surface that once defined your home’s character now makes you wince every time you walk through the room.
Here’s what changes after restoration. The original depth and color come back—not a surface-level shine that fades in weeks, but the actual stone brought back to its natural state. Scratches disappear. Etching from acidic cleaners gets corrected. The finish becomes what it was when the floor was first installed, sometimes over a hundred years ago.
Most Centerport homeowners are surprised by two things. First, how much better the restored marble looks compared to what they thought was possible. Second, how much they save compared to replacement—typically 50-70% less, with the job done in a day or two instead of weeks of construction chaos.
Your floors don’t need to be ripped out. They need someone who knows how to work with old marble the right way.
High Definition Marble Restoration Inc specializes in the restoration work most contractors won’t touch. We’re talking about the 100-year-old floors in Centerport’s historic homes—the ones installed with techniques and materials you don’t see anymore.
We’re owner-operated, which means when you call, you’re talking directly to the person doing the work. No subcontractors. No middlemen who don’t understand the difference between modern marble and the stone in your 1920s foyer.
The New York Times featured our work back in 2001 specifically for historic restoration. Our first client, the Garden City Hotel, has used our services exclusively for over 16 years. We’ve built our reputation on a simple idea: the worse the condition, the better we can show you what real restoration expertise looks like.
Centerport’s older homes have marble that responds differently than modern stone. The installation methods were different. The materials were different. The wear patterns are different. You need someone local who understands how Long Island’s coastal environment and hard water affect these surfaces over decades.
We start with an assessment of what your marble actually needs. Not every floor requires the same approach—a bathroom floor with etching needs different treatment than an entryway with traffic wear. We identify the damage type, the marble variety, and the original finish level.
Next comes the restoration process itself. For most historic marble, we’re removing a microscopic layer of damaged stone using diamond abrasives in progressively finer grits. This eliminates scratches, etching, and stains at the source rather than covering them up. We’re not applying a coating—we’re revealing the actual stone underneath the damage.
The final step is honing and polishing to match the original finish. Some historic floors were installed with a honed (matte) finish, others with high polish. We restore to the authentic look, not just whatever’s easiest. The process typically takes one to two days depending on square footage.
You’ll need to stay off the floors during work and for a few hours after. We handle all the masking and cleanup—you won’t find dust in other rooms or damage to baseboards. When we’re done, you can walk on the floors immediately. No curing time, no waiting weeks to use your own home.

The restoration covers damage removal, surface leveling, and finish restoration. We’re addressing scratches, etching from acidic substances, dullness from wear, water stains, and lippage (where tiles have shifted and created uneven surfaces). If your marble has it, we fix it.
Centerport homes often have specific issues we see repeatedly. Hard water from Long Island’s aquifer leaves mineral deposits that etch into marble over time. Coastal humidity accelerates certain types of deterioration. Older homes sometimes have settlement issues that create cracks or separations in the marble. We’ve worked with all of it.
You also get guidance on proper marble floor care after restoration. Most damage happens because homeowners don’t know that common household cleaners destroy marble. We’ll tell you exactly what to use and what to avoid so your restored floors stay beautiful.
The work includes complete masking and protection of surrounding areas, professional-grade equipment that most cleaning companies don’t have access to, and direct owner involvement. You’re not getting a crew that does generic floor cleaning—you’re getting specialized historic restoration expertise.
For bathrooms, entryways, kitchens, or whole-floor restoration projects, the approach is the same: assess the actual condition, restore using appropriate methods for that specific marble type and age, and deliver results that last.
Restoration typically costs 50-70% less than replacement and takes a fraction of the time. New marble installation in the Long Island area runs $70-190 per square foot when you factor in materials, demolition, disposal, and installation. Most marble restoration runs $5-15 per square foot depending on condition and square footage.
Here’s what that looks like in real numbers. A 200-square-foot entryway would cost $14,000-38,000 to replace with new marble. Restoring that same floor typically runs $1,000-3,000. You save tens of thousands of dollars and avoid weeks of construction disruption.
The time difference matters too. Replacement means demolition, subfloor repair, new installation, grouting, sealing, and curing—easily 1-2 weeks where you can’t use that part of your home. Restoration is usually done in 1-2 days, and you can walk on the floors within hours of completion.
For historic Centerport homes, there’s another cost to consider. Original marble from the early 1900s has character and quality you can’t replicate with modern materials. Replacing it means losing that authentic historic value, which actually decreases your home’s appeal to buyers who specifically seek period details.
Yes. Deep scratches and etching are exactly what restoration is designed to fix. We’re not buffing the surface or applying a coating—we’re removing the damaged layer of stone and revealing undamaged marble underneath.
Etching happens when acidic substances (cleaners, wine, citrus, certain bathroom products) chemically react with marble and dissolve the surface. It looks like dull spots or watermarks. Deep scratches come from dragging furniture, dropped objects, or aggressive cleaning with the wrong tools. Both types of damage go into the stone itself, which is why surface treatments don’t work.
The restoration process uses diamond abrasives in progressively finer grits to remove damage at the stone level. We start with coarser grits to eliminate deep scratches and etching, then move through finer grits to smooth and refine the surface. The final polishing steps bring back the original shine and depth.
There’s a limit—if someone has ground through the entire thickness of the marble tile, we can’t restore what isn’t there. But in 26 years, we’ve rarely encountered damage that severe. Most scratching and etching, even when it looks terrible to you, only affects the top fraction of a millimeter. That’s well within what restoration can fix.
Properly restored and maintained marble can go 10-15 years before needing another full restoration. The longevity depends entirely on traffic levels and how you care for the floors after we’re done.
High-traffic areas like entryways will show wear faster than a master bathroom. If you have kids, dogs, or frequently host gatherings, you’ll see dulling sooner than someone living alone in a quiet household. But even in high-traffic scenarios, you’re looking at a decade-plus before needing major work again.
The key is proper maintenance. Use pH-neutral cleaners made specifically for marble—never vinegar, bleach, ammonia, or typical household cleaners. Put mats at entrances to catch grit that scratches marble. Clean up spills quickly, especially anything acidic. These simple steps dramatically extend the time between restorations.
Some Centerport homeowners opt for periodic maintenance polishing every few years. This is lighter work that addresses minor dulling before it becomes significant. Think of it like getting your car detailed versus getting bodywork done—regular maintenance prevents the need for major restoration as frequently.
We’ll walk you through exactly what your specific marble needs for care. Different marble types have different vulnerabilities, and historic installations sometimes have quirks that affect maintenance.
Polishing is the final step of restoration, but it’s not the same as full restoration. If your marble just needs shine brought back and has no scratches, etching, or stains, polishing alone might be enough. If there’s actual damage, you need restoration first.
Polishing uses very fine abrasives or polishing powders to create a reflective surface on marble that’s already smooth. It’s like waxing a car that has good paint—you’re enhancing what’s already there. This works for marble that’s dull from foot traffic but doesn’t have scratches or etching.
Full restoration includes damage removal before polishing. We’re grinding out scratches, removing etched areas, leveling uneven surfaces, and eliminating stains. Only after that damage is gone do we move to the polishing steps. It’s a complete process, not just a surface treatment.
Many cleaning companies offer “marble polishing” but don’t actually do restoration. They’ll buff your floors with polishing powder, which temporarily improves shine but does nothing for scratches or etching. Within weeks, the floors look bad again because the underlying damage is still there.
When you call, we’ll tell you honestly whether your floors need full restoration or just polishing. There’s no point in selling you more than you need. But if there’s damage, polishing alone won’t fix it—and companies that claim otherwise are setting you up for disappointment.
We restore bathroom floors, shower floors, entryways, kitchens, whole-floor projects—any marble surface that needs restoration. Bathroom floor restoration is actually one of our most common jobs in Centerport’s historic homes.
Bathrooms present specific challenges. The marble is constantly exposed to water, soap, shampoo, and cleaning products. Many of these are acidic and etch marble over time. You end up with dull spots, water stains, and etching around the toilet and shower. The confined space also makes restoration more technical—we need to protect fixtures, walls, and ensure proper ventilation.
Smaller areas like bathrooms don’t cost less per square foot (there’s a minimum to make the job viable), but the total cost is obviously lower than a 500-square-foot foyer. A typical bathroom floor restoration runs $400-800 depending on size and damage level.
The process is the same regardless of room size. We assess the damage, restore using appropriate methods for that marble type, and deliver a finish that matches the original installation. Bathroom or ballroom, the expertise required is identical.
Some homeowners start with a bathroom restoration to see our work before committing to larger areas. That’s fine. Others want everything done at once. Either way, we’re restoring the marble properly—not just making it look better temporarily.
Most store-bought marble cleaners either don’t work or actively damage your floors. The products that claim to restore shine are usually just coating the surface with polymers or wax. The ones that claim to remove stains often contain acids that etch marble worse than the original problem.
Marble is calcium carbonate. Anything acidic—vinegar, lemon, most bathroom cleaners, even some products labeled “marble cleaner”—chemically reacts with that calcium carbonate and dissolves the surface. You’re literally melting microscopic amounts of your floor every time you clean with the wrong product. Over years, this creates the dull, etched appearance that makes you think the marble is worn out.
The coating products are a different problem. They make marble look shiny temporarily by depositing a layer of polymer or wax on top. This wears off quickly in traffic areas, looks streaky, and traps dirt. Worse, when you eventually need real restoration, we have to remove all that coating buildup before we can work on the actual stone. It adds time and cost to the job.
What actually works for maintenance is pH-neutral cleaner made specifically for natural stone, used with a microfiber mop or cloth. No acids, no coatings, no miracle formulas. Just gentle cleaning that doesn’t damage the stone. We’ll recommend specific products after restoration—they’re not expensive, and they actually protect your investment instead of destroying it.
If your marble already has damage, no cleaning product will fix it. You need actual restoration to remove the damaged stone and reveal undamaged marble underneath. There’s no shortcut for that.
