That dull, etched marble you’re looking at right now doesn’t need to be ripped out. It needs someone who knows how to bring it back.
Most of the marble floors in Stony Brook homes—especially the ones in Gold Coast-era properties—were installed using techniques we don’t see anymore. The craftsmanship is there. The quality is there. What’s missing is the finish, and that’s fixable.
Restoration costs a fraction of replacement. We’re talking $5-15 per square foot versus $70-190 for new installation. Most jobs wrap in under two days. And when it’s done, you’re not just getting a clean floor—you’re getting the original surface back, with the depth and character that new marble can’t replicate.
If your marble has lost its shine, shows etching from cleaners, or has stains you can’t remove, you’re in the right place.
High Definition Marble Restoration Inc specializes in one thing: bringing old floors back to life. We’re not a cleaning company that dabbles in stone. We’re a restoration company that focuses on historic marble, terrazzo, and concrete.
The owner oversees every job personally. No subcontractors. No surprises. Just someone who’s spent over 25 years working on the exact type of floors you have in your Stony Brook home.
We were featured in the New York Times back in 2001 for our work on severely damaged historic floors. Our reputation is built on taking jobs other companies walk away from—and delivering results that make you wonder why you ever considered replacement.
First, we assess the condition. Not every floor needs the same approach. Some need honing to remove etching. Others just need polishing to bring back the gloss. We’ll tell you exactly what yours needs.
Next, we prep and protect the space. Floors get masked off. Surrounding areas stay clean. This isn’t a messy process when it’s done right.
Then comes the actual restoration. We use a multi-step diamond polishing process—starting with coarser grits to remove scratches and etching, then moving to finer grits to build the finish. For marble floor care and long-term protection, we apply a penetrating sealer that won’t yellow or peel.
The result is a surface that looks like it did when it was first installed. You’ll see the depth in the stone again. The reflectivity. The reason someone chose marble in the first place.

You get a full assessment before we start. We’ll walk the floor with you, point out what we’re seeing, and explain what needs to happen. No guessing. No upselling.
The restoration itself includes honing if there’s etching or deep scratching, polishing to your preferred finish level (from satin to high-gloss), and sealing with a premium product that actually protects the stone. We also handle marble repair for small chips or cracks, and we’ll re-grout or stabilize loose sections if needed.
In Stony Brook and throughout Nassau County, we see a lot of historic homes with original marble in entryways, bathrooms, and kitchens. These floors have survived a century—they just need proper care. We also offer concrete polishing for homeowners looking to restore or finish basement floors, garage floors, or modern concrete surfaces.
Every job ends with a walkthrough. We’ll show you what we did, explain how to maintain it, and make sure you’re clear on what not to use. Most generic cleaners will etch marble. We’ll tell you what’s safe.
Most residential marble restoration jobs are completed in less than two days. The timeline depends on square footage and the condition of the floor, but we’re not talking about a week-long disruption.
Day one usually involves honing and the initial polishing stages. Day two is finishing, sealing, and cleanup. Smaller areas like bathrooms can often be done in a single day.
We work efficiently because we’ve refined this process over 25 years. You’re not our testing ground. And because the owner is on-site managing the work, there’s no lag time between steps or waiting on subcontractors to show up.
Yes. Etching happens when acidic substances—like vinegar, wine, or most household cleaners—eat into the marble surface. It leaves dull spots that won’t buff out with regular cleaning.
We remove etching by honing the surface with diamond abrasives. This levels out the damaged area and removes the cloudy layer. Then we polish it back up to match the surrounding finish.
If your entire floor is dull, that’s usually from years of micro-scratching and improper cleaning. We address that with a full refinishing process. The marble itself is fine—it just needs the surface restored. This is one of the most common requests we get in older Stony Brook homes, and it’s completely fixable.
By a lot. Marble restoration typically runs $5-15 per square foot depending on condition. Replacement starts around $70 per square foot and can go past $190 when you factor in demo, disposal, new material, and installation.
You’re also keeping the original floor, which matters if you’re in a historic home. Buyers in Nassau and Suffolk Counties pay a premium for original details. Replacing marble with new material can actually hurt resale value if the rest of the home has period-appropriate features.
And there’s the time factor. Restoration takes a day or two. Replacement can take weeks when you account for ordering materials, scheduling demo, and installation. Most people don’t want their entryway or bathroom torn apart for that long.
Polishing is the final step in the process—it’s what creates the shine. Refinishing includes everything: honing to remove damage, polishing to build the finish, and sealing for protection.
If your floor is in decent shape but just looks dull, polishing might be enough. We use progressively finer diamond pads to bring up the gloss without removing much material.
If there’s etching, staining, or scratches, you need refinishing. That means starting with coarser abrasives to level the surface and remove the damaged layer, then working through the polishing stages. It’s more involved, but it’s the only way to actually fix a compromised surface. We’ll tell you which one your floor needs after we see it.
Yes. Bathrooms and kitchens are some of the most common areas we work in. They’re also where marble tends to take the most abuse—soap scum, hard water, spills, acidic cleaners.
Bathroom floor restoration usually involves dealing with etching around the vanity and shower, plus any staining from products that have been sitting on the stone. We’ll hone out the damage, re-polish, and seal it so water and soap don’t penetrate as easily.
Kitchens are trickier because of food and drink spills, but the process is the same. We’ve restored marble floors in Stony Brook kitchens that hadn’t been touched in decades. The stone holds up—it just needs someone who knows how to work with it. We also restore marble countertops, though floors are our primary focus.
Use a pH-neutral cleaner made for stone. That’s it. Most damage we see comes from people using the wrong products—anything acidic will etch marble, and anything abrasive will scratch it.
Wipe up spills quickly, especially anything acidic like wine, coffee, or citrus. The sealer we apply helps, but it’s not a force field. It buys you time, not immunity.
For daily cleaning, a damp microfiber mop with a stone-safe cleaner is all you need. Don’t use vinegar, bleach, or general-purpose cleaners. And skip the oil soaps—they leave residue that dulls the finish over time. We’ll give you specific product recommendations when we finish the job.
