That dull, etched marble floor you’ve been scrubbing for years? It’s gleaming again. The shine you remember when you first fell in love with the house—that’s back.
No more avoiding certain angles of light that show every scratch. No more explaining to guests that “it used to look better.” Your marble floors look the way they were meant to look when they were installed a century ago.
And you didn’t have to rip out irreplaceable stone to get there. Most Port Washington North homeowners are quoted $15,000 to $30,000 for marble replacement. Professional marble floor restoration typically costs 60-80% less and takes days, not weeks. You keep the original craftsmanship that adds value to your home, and you get a result that lasts 10-15 years with proper care.
The difference isn’t just visual. It’s knowing you made the smarter choice—one that respects the history of your home while giving you a floor you’re actually proud to show off.
High Definition Marble Restoration Inc has been restoring historic floors throughout Nassau County since 1998. We’re owner-operated, which means the person who quotes your job is the same person overseeing the work.
Port Washington North’s Gold Coast heritage means many homes here feature original marble installations from the early 1900s. That’s our specialty. The worse the condition, the better we are at bringing it back. We’ve restored marble staircases, bathroom floors, and entryways that other contractors said needed full replacement.
We were featured in The New York Times for our restoration work, and we’ve maintained exclusive partnerships with high-end clients like the Garden City Hotel for over 16 years. That’s not because we’re the cheapest option. It’s because we understand how to work with antique stone—the installation methods, the mineral composition, the techniques that actually restore without causing further damage.
First, we assess the damage. Not all marble floors need the same level of work. Some need light polishing. Others require grinding to remove deep etching or lippage from settling. We’ll tell you upfront what your floor actually needs—not what makes us the most money.
If grinding is necessary, we start there using professional diamond abrasives. This removes the damaged layer and levels the surface. Then we move through progressive polishing stages, each one finer than the last, until we’ve rebuilt the shine from within the stone itself.
We’re not applying a topical coating that wears off in six months. We’re physically restoring the marble’s natural ability to reflect light. That’s why the results last years, not months.
Throughout the process, we mask and protect everything around the work area. Your home stays clean. Most marble floor polishing projects in Port Washington North take one to three days depending on square footage and damage severity. You’re not living in a construction zone for weeks.
When we’re done, your floor is sealed properly using products designed for the specific type of marble in your home. Because stone types vary—Carrara marble needs different treatment than Calacatta or Tennessee marble—and generic approaches cause problems down the road.

You get a full assessment before any work starts. We identify the type of marble, the installation method, and the specific damage patterns. This matters because 100-year-old floors in Port Washington North were often installed differently than modern stone, and restoration techniques need to account for that.
The restoration itself includes grinding if needed, multi-stage polishing, repair of any cracks or chips, and proper sealing. We also address common issues specific to Nassau County homes—hard water etching on bathroom marble floors, mineral deposits from Long Island’s water supply, and damage from acidic cleaners that previous owners may have used.
We work on marble staircases, entryway floors, bathroom floors, kitchen countertops, and any other marble surface that needs refinishing. We also handle granite, limestone, and terrazzo using the same careful approach. Our equipment includes professional-grade grinders, polishers, and steam cleaning systems that reach 356°F to sanitize while restoring.
What you won’t get: subcontractors. The owner oversees every project personally. You also won’t get surprise charges or upselling once we start. The quote we give you is the price you pay. And you won’t get a crew that damages your walls, trim, or adjacent flooring. We’ve been doing this for over two decades—we know how to protect your home while we work.
Most marble floor restoration projects in Port Washington North range from $3 to $12 per square foot depending on the condition and size of the area. A typical 200-square-foot entryway usually costs between $600 and $2,400 for complete restoration.
Compare that to replacement costs. New marble installation runs $15 to $40 per square foot once you factor in demolition, disposal, materials, and labor. That same 200-square-foot entryway could easily cost $5,000 to $10,000 to replace.
The cost difference becomes even more significant when you consider what you’re losing. Original marble in historic Port Washington North homes is often higher quality than what’s available today. You literally cannot buy that density and character in the current market. Restoration preserves that value while costing a fraction of replacement.
Most residential marble floor polishing projects take one to three days. A simple polish on marble that’s in decent shape might be done in a single day. More extensive restoration that requires grinding, repair work, and multi-stage polishing typically takes two to three days.
The timeline depends on square footage, damage severity, and whether we’re working around furniture. We’ll give you an accurate timeframe during the initial assessment. What we won’t do is drag out the job unnecessarily or leave your home in chaos for weeks.
For context, marble replacement projects often take two to four weeks once you account for demolition, disposal, ordering new stone, and installation. You’re living in a construction zone that entire time. Restoration gets you back to normal life much faster while delivering results that last 10-15 years with proper maintenance.
Yes. Acid etching is one of the most common types of damage we fix on marble floors throughout Nassau County. When acidic cleaners like vinegar or harsh bathroom products contact marble, they dissolve the calcium carbonate layer, leaving dull, rough patches that can’t be buffed out with DIY methods.
The damage happens at a microscopic level. The marble’s surface structure is compromised, which is why it looks cloudy and feels rough. Professional restoration removes that damaged layer through controlled grinding, then rebuilds the polish through progressive refinishing stages.
We see this frequently on bathroom marble floors in Port Washington North where homeowners used products that seemed safe but were actually destroying the stone over time. The good news is that etching damage, even severe etching, is almost always reversible with proper restoration techniques. The marble underneath is still sound—we just need to get down to it and restore the finish correctly.
Restoration is almost always the better choice for historic marble floors in Port Washington North, especially if the original stone isn’t cracked through or structurally compromised. Original marble from the early 1900s often has superior density and character compared to contemporary stone.
Replacement means losing that quality and the authentic character that makes Gold Coast-area homes valuable. You’re also dealing with the mess and expense of demolition, disposal, and installation. Most homeowners don’t realize how disruptive full replacement is until they’re living through it.
The only time replacement makes sense is if the marble is severely cracked, broken, or has been ground down so many times that there’s not enough material left to work with. That’s rare. In 25 years of restoration work, we’ve encountered very few floors that truly needed replacement. Most just needed someone who knew how to restore them properly instead of taking the easy route and recommending a tear-out.
Etching and dull spots require physical restoration, not cleaning. The marble’s surface has been chemically altered or mechanically worn down, so no amount of scrubbing or store-bought polish will fix it. You need to remove the damaged layer and rebuild the finish.
We start by identifying the depth of the damage. Light etching might only require honing and polishing. Deeper etching needs grinding first to level the surface and remove the compromised stone. Then we move through progressive polishing stages using finer and finer diamond abrasives until the marble’s natural shine is restored.
This isn’t a coating or topical treatment. We’re restoring the stone’s actual ability to reflect light by refining the surface at a microscopic level. That’s why professionally restored marble lasts 10-15 years instead of six months. The shine is coming from within the stone itself, not from a product sitting on top that wears away with foot traffic.
Yes. Marble staircases and bathroom floors are common restoration projects for us throughout Port Washington North. Both present specific challenges that require experience with historic installations.
Marble staircases often show wear patterns on the treads from decades of foot traffic. We restore each step individually, addressing lippage issues where settling has caused uneven surfaces between treads. Most staircase restorations take two to three days depending on the number of steps and damage severity.
Bathroom marble floors deal with different issues—hard water etching, soap scum buildup that’s been scrubbed in rather than removed, and damage from acidic cleaning products. Nassau County’s mineral-rich water is particularly hard on marble, leaving calcium and magnesium deposits that react with the stone if not addressed properly. We use professional steam cleaning at 356°F to remove buildup without harsh chemicals, then restore the marble’s finish using the same grinding and polishing process we use on floors.
