Marble & Natural Stone Restoration
The change in your stone guides the work.
We look at the stone and finish, including earlier treatments. Edges and surrounding fixtures also shape the discussion about repair or finish work.

Read the condition
Look at the mark—and the surface around it.
A close-up can show the mark. A wider view shows the finish, location, edges, fixtures, and use that may change the work.
Etching and dullness
A pale, cloudy, or low-sheen area may be a change to the surface finish rather than dirt sitting on top.
Staining and discoloration
A darker or differently colored area may involve moisture, oil, pigment, residue, or another substance within or on the surface.
Chips, cracks, seams, and edges
Location, movement, missing material, earlier repair, and the surrounding finish affect the available repair path.
Know the difference
Etching and staining are not the same problem.
Etching
Acid reacts with acid-sensitive stone and changes the finish at the surface. The area may look pale, dull, or different in reflected light.
Staining
A substance changes the visible color within or beneath the surface. The mark may look darker, tinted, or uneven.
What the scope may include
The material and finish determine the work.
Cleaning and sealing
Cleaning addresses compatible surface soil and residue. Sealing may help manage absorption; it does not make every material stain-proof or stop marble from etching.
Honing, polishing, and finish restoration
Progressively refined abrasives may address wear or return a compatible honed or polished finish. The stone and condition determine the method.
Chip, crack, seam, and edge repair
A localized repair can improve a damaged detail. Color, movement, fill, edge shape, lighting, and viewing angle affect what remains visible.
Counters, vanities, floors, stairs, and architectural stone
The written scope must account for access, fixtures, adjoining materials, occupied rooms, and how the surface is used.
From the Restoration team
Jesus Alvarez explains etching, resurfacing, and sealing.
Jesus demonstrates how an untreated marble surface reacts to acid and explains why existing etching, resurfacing, and sealing are separate questions.

[00:02.420] [Jesus Alvarez] My name is Jesus Alvarez. I work with Fox
[00:04.540] Marble. Pretty much anything stone care
[00:05.960] related, any damage you have on your natural stone, that's where we come in.
[00:09.760] We're just going to do a little demonstration
[00:10.720] here on what lemon does to an untreated surface.
[00:15.760] Go ahead and pour some on here. A bit more on this one here.
[00:20.480] On black surfaces, when you do get an etch mark, it shows really white,
[00:24.680] so it's really an eyesore. You'll be able to
[00:27.200] tell how the coating actually protects it.
[00:29.740] Even now, you can kind of see it starting to dissolve the calcium
[00:32.620] in the marble itself. You see the bubbling on here as well.
[00:38.120] If your stone has already shown etch marks,
[00:40.940] stains, scratches, things like that,
[00:42.480] we will send our crew out there, make sure
[00:44.280] everything's protected, then they do a wet sanding.
[00:47.380] Diamond pads resurface everything. That's
[00:50.400] the only way to get rid of the etch marks,
[00:51.780] by actually re-sanding everything and
[00:53.960] then reapplying a sealer of your choice.
[00:56.640] For me, the main recommendation for white marbles is always a
[00:59.140] coating. People mainly, they really like the white marbles.
[01:02.420] Sometimes they're a little bit scared of having that in their
[01:04.620] kitchen because people didn’t really like the maintenance behind it.
[01:07.220] As soon as you pretty much drop anything, it
[01:09.800] leaves a mark. With impregnating sealers,
[01:11.860] it gives you a little bit of time to wipe up, but
[01:14.460] if you leave it long enough, it will leave a mark.
[01:17.020] With the coatings, you don't have to worry about that.
[01:19.420] You spill something, you could leave it there overnight,
[01:22.340] come back the next day, wipe it off, and you have zero damage to the marble.
[01:27.420] One issue we used to see was people wanting limestone
[01:30.400] outdoors, outdoor barbecues, things like that,
[01:34.680] but same thing, it’s too porous, to where people didn’t want to deal
[01:37.660] with that maintenance of etch marks, stains, and things like that.
[01:40.960] Now there's a coating specifically designed for outdoors,
[01:43.940] UV resistant, that can be applied on vertical surfaces.
[01:46.960] It gives you the same peace of mind. You can leave something
[01:50.180] overnight, come back, wipe it off, and live with it.
[01:53.960] We've had a lot of success, like I said,
[01:55.960] mainly in commercial, high-traffic areas.
[01:59.200] You could give us a call. We'll go out there, resurface it, keep it
[02:02.240] maintained, maybe even do a yearly contract to keep it maintained,
[02:06.520] because with natural stone, you want to keep up with the maintenance before
[02:09.660] it's too late. Natural stone is beautiful. You want to maintain that.
Visual alternative
[00:00] The Fox Marble logo appears over a house exterior. Jesus Alvarez sits beside a pale kitchen counter. Spoken captions are also printed on the original video.
[00:09] Jesus stands at the counter with a pale stone surface and a small dark green veined sample. He squeezes lemon onto both, then points out the affected areas.
[00:35] A close-up shows a pale, foamy-looking patch on the dark green sample. The view moves to marks on the pale counter, which Jesus points toward. The remaining footage returns to him seated beside the counter.
[02:13] The closing card shows the Fox Marble logo and the words, Excellence from the Ground Up.
Material fit, preparation and care requirements are assessed for your particular surface.
A closer look

Two documented views of the same stair surface. Every existing surface needs its own assessment.
Marble care, in our clients’ words.
“Fox Marble did a spectacular job wet sanding and sealing my Carrara Marble kitchen countertops. They also fixed several chips, and the price was reasonable.”
“Al from Fox Marble did a wonderful, professional job sanding and repolishing with premium sealer our Carrara marble island.”
“We had a great experience with your company. Renee was punctual, professional and really educated us in the process. Our marble countertop has never looked so good! Your scheduler was a great communicator”
Questions worth answering
Before Fox recommends the work.
What is the difference between an etch mark and a stain?
Etching changes the stone’s surface finish and is often most visible in reflected light. A stain changes the visible color within or beneath the surface. Photos help, but the stone may need inspection before the condition is confirmed.
Does sealing prevent marble from etching?
Ordinary penetrating sealers are generally intended to help manage absorption. They do not stop the acid reaction that causes marble and other acid-sensitive stone to etch. MORE® AntiEtch™ is a separate, product-specific protection path.
Can you repair localized stone damage?
We can assess localized stone damage and discuss available repair options. The material and any missing pieces affect the repair. Movement and edge shape can limit the options. Previous repairs and your visual expectations are part of the assessment.
When does stone need honing or polishing?
Wear and scratches can affect the finish. Etching or inconsistent sheen may also be a reason to consider honing or polishing. The existing finish and condition determine whether localized or broader work is appropriate.
How often should natural stone be sealed?
There is no reliable universal schedule. The decision depends on porosity and the sealer used. Your use and cleaning routine can change what the surface needs. Location and prior treatments also affect the decision. The surface should be evaluated instead of resealed only because time has passed.
What photos should I send?
Include one close-up in natural light, one photo showing how the mark reflects light, and one wider view of the surface in its room.
