Your marble floors don’t need to be ripped out. Most damage you’re seeing—etching from acidic cleaners, dullness from years of wear, water stains from Long Island’s notoriously hard water—can be reversed through professional marble restoration.
You get the original beauty back without the mess, cost, or weeks of construction that come with replacement. Most restoration projects wrap up in one to three days, and you’re looking at $1 to $3 per square foot instead of $6 to $20 for new stone, plus all the demolition and disposal fees.
The result is a floor that looks like it did when your home was built, with a finish that’s protected and built to last. No shortcuts. No temporary fixes. Just expert marble floor polishing and refinishing that brings the character of your historic Locust Valley home back to the surface.
High Definition Marble Restoration Inc has spent over 25 years working on Nassau and Suffolk County’s most challenging floors. We’re not a cleaning service. We’re a marble restoration company that specializes in the kind of historic, pre-World War II marble that defines homes in Locust Valley.
The owner oversees every project personally. That means you’re getting 35 years of refined expertise on your floor, not a crew that’s learning as they go. We’ve been featured in the New York Times for our work, and the Garden City Hotel has trusted us exclusively for over 16 years.
Locust Valley’s homes aren’t just old—they’re part of Long Island’s Gold Coast legacy, with estates dating back to the early 1900s. We understand what it takes to restore marble from that era, and we treat every floor like it’s our own.
We start with a free on-site assessment where we evaluate the damage, identify the type of marble, and give you transparent pricing before any work begins. No surprises. No upselling once we’re there.
The restoration itself uses water-based methods that keep 99% of the work dust-free. We mask off surrounding areas to protect your home, then begin the process of removing etching, stains, and surface damage using techniques developed over decades. For historic floors, this often means working with materials and finishes that aren’t made anymore—something most contractors don’t know how to handle.
Once the surface is restored, we polish and seal the marble to bring back its original luster and protect it from future damage. The space stays clean throughout, and we don’t leave until everything is pristine. Most jobs are done in one to three days, and you’re left with a floor that looks like it was just installed—not replaced.

You’re getting a complete marble floor restoration that addresses etching, staining, scratches, dullness, and water damage. We handle everything from bathroom floor restoration to grand entrance halls with 100-year-old Carrara marble.
Our process includes surface repair, honing to remove imperfections, polishing to restore shine, and sealing to protect against future damage. We also offer marble refinishing for floors that have lost their finish over time, and we’ve recently added concrete restoration and polishing for clients looking to modernize certain spaces while keeping the historic character intact elsewhere.
Locust Valley’s homes face unique challenges. The median construction year here is between 1945 and 1948, meaning many floors are original to the home. Long Island’s hard water creates mineral buildup that standard cleaning can’t touch. Acidic household cleaners—even something as common as vinegar or certain toilet bowl cleaners—can etch marble on contact, and the damage is immediate.
We’ve seen it all, and we know how to fix it. Every project comes with a comprehensive warranty that protects your investment long-term, and because the owner is directly involved, you’re getting accountability from start to finish.
Marble floor restoration typically costs $1 to $3 per square foot, while replacing the same floor runs $6 to $20 per square foot for materials alone. That doesn’t include demolition, disposal fees, potential plumbing or structural modifications, or the weeks of construction disruption.
For a 200-square-foot entryway, you’re looking at $200 to $600 for restoration versus $1,200 to $4,000-plus for replacement. The math gets even more dramatic on larger spaces. Restoration also preserves the original marble, which matters if you’re in a historic Locust Valley home where authenticity and character are part of the property’s value.
Most homeowners don’t realize how much can be saved through professional marble repair and refinishing. Unless the marble is structurally compromised—cracked through the slab or missing large sections—restoration is almost always the smarter financial and aesthetic choice.
Yes. Acidic damage is one of the most common problems we fix, and it’s also one of the most misunderstood. When acidic cleaners like vinegar, toilet bowl cleaners, or even some “natural” products touch marble, they cause a chemical reaction that etches the surface. It’s not a stain—it’s actual damage to the stone.
The good news is that etching can be removed through professional honing and polishing. We carefully remove the damaged layer, smooth the surface, and restore the original finish. DIY methods and store-bought products usually make it worse because they’re either too abrasive or not abrasive enough, and they don’t address the underlying issue.
If your marble looks dull, cloudy, or has ring marks where cleaners were used, that’s etching. It’s fixable, and it doesn’t require replacement. We’ve restored floors with decades of acidic damage, and the results look like the damage never happened.
Most marble floor restoration projects are completed in one to three days, depending on the size of the space and the extent of the damage. A standard bathroom floor might take a day. A large entryway or living area with significant etching and staining could take two to three days.
The process itself is efficient because we’re not tearing anything out or waiting for new materials to arrive. We work on-site using water-based methods that keep dust to a minimum, and we don’t leave until the job is done right. You’re not dealing with weeks of construction or contractors coming and going.
For historic floors—especially those over 100 years old—we may take a bit more time to ensure we’re preserving the original character while bringing the surface back to life. But even then, you’re talking days, not weeks. And because the owner oversees every project, there’s no waiting around for approvals or dealing with miscommunication between crews.
We specialize in historic marble, which means we’re equipped to handle the types of stone and finishes that were used in early 20th-century construction. That includes Carrara, Calacatta, Crema Marfil, Emperador, and other classic marbles that were popular in Gold Coast estates and pre-WWII homes throughout Locust Valley.
Historic marble is different from modern installations. The stone itself may have different mineral compositions depending on when and where it was quarried, and the finishing techniques used decades ago aren’t the same as what’s done today. That requires specialized knowledge—not just standard cleaning or surface-level polishing.
We’ve worked on marble floors, staircases, entryways, and bathroom floors in homes dating back over a century. The worse the condition, the better the transformation. If your marble has been neglected, covered up, or damaged over the years, we can bring it back. We also don’t work with porcelain, so if you’ve got real marble, you’re in the right place.
No. Professional marble restoration is designed to preserve the stone, not damage it. We use techniques that have been refined over 35 years to remove surface damage without compromising the integrity of the marble itself.
The risk of damage comes from DIY attempts or hiring contractors who don’t specialize in marble. Abrasive pads, harsh chemicals, and improper polishing methods can scratch the surface, strip protective layers, or create uneven finishes that make the problem worse. We’ve fixed plenty of floors where a well-meaning homeowner or general contractor tried to “buff it out” and ended up causing more harm.
Our process is controlled, methodical, and tailored to the specific type of marble and the condition it’s in. We’re not guessing. We’re applying decades of hands-on experience to bring your floor back to life the right way. And because we’re owner-operated, the person making decisions on your floor is the same person who’s built a reputation on getting it right.
Yes. If your marble floor is in decent shape but has lost its shine or looks dull from years of foot traffic, marble polishing services can bring back the luster without a full restoration. Polishing is less intensive than honing and refinishing, and it’s a cost-effective way to maintain floors that don’t have significant damage.
We assess the condition during the free quote and recommend the level of work that actually makes sense for your floor. If polishing is enough, we’ll tell you. If you need more extensive marble floor care—like honing to remove etching or sealing to protect against future damage—we’ll explain why and what the difference will be.
Floor marble polishing typically takes less time than full restoration, and the results are immediate. You’ll see the shine come back, and the surface will feel smoother underfoot. For Locust Valley homeowners who want to maintain their marble rather than wait until it needs major repair, regular polishing is a smart investment that extends the life of the floor and keeps it looking sharp.
