Limestone, slate, onyx, terrazzo, soapstone, flagstone. Each one needs different diamond pads, different chemicals, and a different finish target. We work all of them, in your home, on the original installation. No two stones are polished the same way, and we know which is which. Serving Laguna Beach, Crystal Cove, Irvine, and the rest of Orange County.

Not every natural stone polishing project needs the same finish. Here's how the common options compare so you can pick the right one for your space.
Marble Polish Full diamond progression to 3000 grit on Carrara, Calacatta, and other true marbles. Mirror finish that matches factory polish. Available as part of multi-stone restorations when marble appears alongside other stones in the same home.
Granite Polish Diamond polish with a final granite-specific compound pass. Restores wet-look depth on granite floors and counters that have gone matte from wear. Harder stone than marble, so it holds the polish longer.
Limestone Hone Light diamond progression to 400 or 600 grit for a soft satin matte. Limestone won't hold a high polish, so a hone is the best long-term finish. We seal with a high-absorption impregnator since limestone is porous.
Travertine Polish Hole-fill with color-matched epoxy followed by full diamond polish. Available alongside marble or limestone polishing when multiple stones are present in the same home. Indoor and outdoor finishes both supported.
Slate Cleaning + Enhance Deep enzymatic clean to pull dirt out of the natural cleft, followed by a penetrating color enhancer that deepens the natural blacks, blues, and greens. Topical sealer for protection. We do not grind slate.
Onyx Polish Hand-polished with ultra-fine diamonds and cerium oxide compound. Light passes only since onyx is brittle. Brings out the translucent depth of backlit onyx walls and bar tops. Smaller projects, treated like fine cabinetry.
What working with us actually looks like
We confirm what you actually have. Many homeowners are told 'marble' and it's limestone, or 'granite' and it's quartzite. The wrong assumption means the wrong diamonds and the wrong sealer. We test with a few drops of water, a scratch test in a hidden corner, and visual inspection of the grain.
A 1x1 or 2x2 test area in a low-visibility spot shows you the achievable finish. Some stones polish to a high gloss, some only hone, some require enhancement instead of polish. The test removes the guesswork before we commit to the whole floor.
Diamond progression calibrated to the stone's hardness and porosity. Limestone gets a softer touch than marble. Onyx gets hand-polishing on the edges. Terrazzo gets a densifier between grits. Slate gets cleaned and enhanced, not ground. We don't use a generic process.
Porous stones (limestone, sandstone, flagstone) get an impregnating sealer rated for high absorption. Dense stones (quartzite, soapstone) get a lighter penetrating sealer or, for soapstone, mineral oil only. We tell you which to use for refresh coats and how often.

Limestone is softer and more porous than marble. The same diamond pad that polishes marble to a mirror will burn limestone or expose voids in it. We use a finer-grit progression with less aggressive abrasive, stop at a satin hone instead of full polish, and use a higher-absorption sealer. Limestone also etches faster than marble, so a hone is more forgiving long-term than a polish.
Not in the way most people mean. Slate has a natural cleft texture that gives it character, and grinding it smooth destroys that. What we do for slate is a deep enzymatic clean to pull dirt and old wax out of the cleft, then color enhancement with a penetrating enhancer like Aqua Mix Enhancer Pro to deepen the natural blacks, blues, and greens. Then a topical sealer for protection. The result looks freshly installed.
Restore it almost always. Vintage terrazzo from the 1950s and 1960s is irreplaceable. The marble chip aggregate, the original color matrix, and the patina take 70 years to develop. We grind, densify, and polish to expose fresh aggregate and bring back the original gloss. Repair costs run a fraction of replacement, and you keep the character of the home.
Slow and by hand. Onyx is brittle and translucent, so we use light passes with ultra-fine diamonds (mostly 800, 1500, 3000) and finish with cerium oxide compound. Edges are hand-polished with rubber-backed pads. We never use heavy machines on onyx. Most onyx jobs are smaller, like a feature wall or a bar top, and we treat them more like fine cabinetry than flooring.
Soapstone is soft enough to scratch with a fingernail and doesn't need sealer. We polish lightly with very fine pads if there are deep scratches, then apply mineral oil to deepen the color. The oil refreshes every few weeks for the first year, then less often as the stone naturally develops a patina. Soapstone is the most low-maintenance stone we work with.
Send us a few photos and we'll usually identify it from the grain pattern, color, and surface character. If we can't tell from photos, we identify on site with a hardness test and a drop of dilute acid in a hidden corner. The acid bubbles on calcium carbonate (marble, limestone, travertine, onyx) and does nothing on silica-based stones (granite, quartzite, slate). Five-minute test.
Most surface dullness and traffic wear comes out with the polishing pass. Deep stains from oil, rust, or organic material need a poultice applied first, which sits 24 to 48 hours and pulls the stain up out of the pores. We add poultice work to the quote when we see staining at the walk.
