Your marble floors look like new again. Not “better than they were”—actually restored to the way they looked when your house was built.
That means no more dull spots where water sat too long. No more etching from cleaners you didn’t know were too harsh. No more embarrassment when guests walk through your entryway or bathroom.
Most jobs finish in one to two days. You’re not living in a construction zone for weeks. Showers are usable the next day. Kitchen backsplashes get done in a single day. And when we’re finished, your floors don’t just look good—they’re protected against the same damage that brought us here in the first place.
Well-maintained original marble can increase your property value by three to five percent. Buyers pay more for authentic restored features. They can tell the difference between original craftsmanship and modern replacement, and they’re willing to pay for it.
High Definition Marble Restoration Inc specializes in historic floor restoration across Nassau County. We’re owner-operated, which means the person who quotes your job is the same person overseeing the work. No subcontractors. No handoffs.
We’ve spent over 25 years working on the exact type of homes you see throughout Plainedge—properties built in the 1940s through 1960s with original marble installations. These floors were installed using techniques that don’t exist anymore, and they require someone who understands how those materials behave.
The New York Times featured our work back in 2001. We’ve restored marble across Long Island, from century-old floors in historic homes to damaged surfaces that other companies said needed full replacement. The worse the floor, the better we are at bringing it back.
First, we assess the damage. Marble gets ruined in predictable ways—etching from acidic cleaners, hard water buildup (extremely common in Nassau County), scratches from grit, and dullness from years of wear. We identify what’s happening with your specific floors.
Then we use a diamond restoration process. This isn’t a topical fix. We mechanically remove the damaged surface using diamond pads that grind down the stone and expose fresh material underneath. No harsh chemicals. No coatings that peel off in six months. Just the actual stone, brought back to a mirror-like shine.
After polishing, we seal the surface. This protects against future buildup and gives you time to clean spills before they etch. We also walk you through what products to avoid—because the biggest mistake people make is going back to the same cleaners that caused the damage in the first place.
You get transparent pricing before we start. You know what you’re paying upfront. And we mask and protect everything during the work, so your home stays clean throughout the process.

You get a full evaluation of your marble’s condition and a clear explanation of what’s causing the damage. We don’t upsell services you don’t need. If your floors can be restored, we’ll tell you. If they’re beyond repair, we’ll tell you that too.
The restoration itself includes diamond grinding to remove surface damage, progressive polishing to bring out the stone’s natural shine, and professional sealing to protect the finish. We handle bathroom floors, kitchen backsplashes, entryways, and any other marble surface in your home.
Plainedge homes—especially those built between 1940 and 1969—often have original marble that’s never been properly maintained. Hard water from local sources leaves white crusty deposits. Standard household cleaners contain acids that etch the surface. And most cleaning companies make things worse by using harsh abrasives that strip away the stone.
We also offer concrete restoration and polishing, a newer service for homeowners looking to refinish basement floors or garage surfaces. Same process, different material. And we don’t touch porcelain—we stick to what we know.
Most marble restoration projects take one to two days depending on the size and condition of the floors. A standard bathroom floor usually gets done in a day. Larger spaces like entryways or multiple rooms might stretch into a second day.
Showers are usable the next day after we finish. Kitchen backsplashes get completed in a single day. We’re not talking about week-long projects that disrupt your entire household.
The timeline depends on how damaged the marble is and how much surface area we’re covering. During your free quote, we’ll give you an exact timeframe based on your specific floors. No surprises.
Yes. Etching and water damage are exactly what we specialize in. Etching happens when acidic cleaners eat into the marble’s surface, leaving dull spots that won’t shine no matter how much you clean. Water damage—especially common in Nassau County due to mineral-heavy local water—leaves white crusty buildups that look permanent.
Both problems get fixed through our diamond restoration process. We grind down past the damaged layer and expose fresh stone underneath. This isn’t a coating or a topical treatment. We’re removing the actual damaged material and bringing out new surface.
The worse the damage, the more grinding we do. But unless the marble is cracked all the way through or structurally compromised, we can usually bring it back. We’ve restored 100-year-old floors that looked completely ruined.
Almost always, yes. Replacement means ripping out the old marble, disposing of it, buying new material, and paying for installation. You’re looking at significant costs and a much longer timeline.
Restoration costs a fraction of that and finishes faster. Plus, you keep your original floors—which matters if you have historic marble that can’t be replicated with modern materials.
Original marble also adds value to your home in ways new marble doesn’t. Buyers pay a premium for authentic period features. When you restore instead of replace, you’re maintaining the character and craftsmanship that makes Plainedge homes special. Once original floors are gone, they’re gone forever.
Going back to the same cleaning products that caused the damage in the first place. Vinegar-based cleaners, citrus cleaners, and most standard bathroom cleaners contain acids that etch marble. They’re marketed as “natural” or “tough on grime,” but they destroy stone.
After we restore your floors, we walk you through exactly what to use and what to avoid. You need pH-neutral cleaners specifically made for natural stone. Anything else will etch the surface again, and you’ll be right back where you started.
The second mistake is ignoring spills. Even water can cause problems if it sits long enough, especially in Nassau County where mineral content is high. Wipe up spills quickly, and your restored marble will stay beautiful for years.
We specialize in marble restoration, but we also handle other natural stone surfaces like travertine, limestone, and terrazzo. Each material has different mineral compositions and requires slightly different techniques, but the core process is the same—diamond grinding, polishing, and sealing.
We also offer concrete restoration and polishing, which is a newer service we’ve added for homeowners looking to refinish basement or garage floors. Same mechanical process, just applied to a different material.
What we don’t do is porcelain. Porcelain requires completely different tools and methods, and we’d rather stick to what we know than try to be everything to everyone. If your floors are natural stone or concrete, we can help. If they’re porcelain, we’ll point you toward someone who specializes in that.
Because the person who quotes your job is the same person overseeing the work. You’re not dealing with a sales rep who hands your project off to a subcontractor who may or may not know what they’re doing.
Owner-operated means direct accountability. If something isn’t right, you’re talking to the person who can actually fix it. There’s no chain of communication, no finger-pointing, no “that’s not my department.”
It also means we treat every project like it’s our own. We’ve been doing this since 1998, and our reputation is built on the quality of every single job. We’re not running a high-volume operation where speed matters more than results. We’re focused on doing the work right, and that only happens when the owner is involved from start to finish.
