TopStone Granite repairs chipped, cracked, pitted and stained granite countertops for Baltimore homeowners and businesses. We fix edge chips beside sinks and dishwashers, cracks across sink rails, open seams and dark oil spots, then polish and seal the area so it blends back into the slab.
Granite is hard, but it is also brittle and full of mixed crystals, which makes it easy to chip and tricky to color match. As a fabricator with 15+ years in stone and 650+ jobs completed, we know how granite is cut, rodded, seamed and polished, which is exactly what you need to know to put it back together.
We repair granite we installed and granite we did not, in kitchens, baths and bars across Baltimore and the surrounding area. TopStone Granite is licensed and insured under MHIC #145977.
Most granite damage can be repaired with the countertop in place, in one visit. Our granite countertop repair work covers:
Rounded edges like a full or half bullnose are the hardest to rebuild because the curve has to be shaped by hand after the fill cures. Done right, the profile runs through the repair without a flat spot. For an overview of repairs on every stone, visit our countertop repair hub.
Granite fails in predictable places. Knowing where it breaks, and why, tells us whether a repair is cosmetic or a warning sign.
The front edge by the sink takes hits from pots, heavy dishes and faucet sprayers. Over a dishwasher, the opening door can knock the underside of the edge. These chips are usually small and fill well, especially on darker granites.
The narrow strips of stone in front of and behind a sink or cooktop are the weakest parts of any granite top. Good fabricators reinforce them with steel or fiberglass rods set into the underside, and tops that skipped that step are the ones that crack. Leaning on the sink edge or a cabinet that settles can finish the job.
Run a fingernail across the line. A fissure is a natural seam in the crystal structure and your nail will glide over it, while a crack usually catches.
Look at the edge and, if you can, the underside from inside the cabinet, because a crack often shows through and a fissure rarely does. Our article on a crack in a granite countertop covers this in more detail.
Coarse-grained granites can lose small flakes of mica or feldspar, leaving pits that collect crumbs. Pits are a natural trait, not a defect, but they can be filled with clear or tinted resin so the surface feels smooth again.
Cooking oil darkens granite in a blotch that does not wipe off. Water marks around faucets often come from minerals or a worn seal. We lift oil stains with a poultice that draws the oil back out of the stone, then reseal the spot.
A good granite repair is about preparation and color, not just glue. These are the three stages that decide whether a fill lasts and disappears.
Cooking oil, soap film and moisture inside the chip stop resin from bonding. We clean the area with a solvent and let it dry fully before any fill goes in. Skipping this is why many repair kit fills turn cloudy or pop out.
Granite is a mix of crystals in several colors, so we tint the fill to the dominant background color and sometimes add fine specks to break up the patch. Epoxy is used for cracks and larger fills, while fast-setting acrylic adhesives suit small chips. The color is matched on site, against your stone, in your light.
The fill is left slightly proud of the surface and allowed to harden. We shave it flush with a razor blade, then polish through progressively finer diamond pads until the gloss matches the surrounding granite. A matte spot is a giveaway, so sheen matters as much as color.
Granite seam repair is one of the most common calls on older tops. Seams open or develop a height difference, called lippage, when the original epoxy breaks down, the cabinets settle, or the seam was never set level in the first place.
To repair a seam, we cut out the failed filler and clean both edges back to sound stone. The pieces are pulled tight and level with a seam setter, a vacuum-cup clamp that grips both sides, and the joint is refilled with color-matched epoxy. Any remaining lippage is ground flush and re-polished.
If a seam keeps opening, the cabinet underneath is usually moving, and that has to be shimmed or fixed first. You can read about how seams are planned on a new top on our seam matching page. Seams that open right at the sink often go together with a failing sink mount, which our undermount sink repair page covers.
We would rather tell you a repair will not work than take your money for one that fails. Replacement, of that piece or the whole run, is usually the smarter choice in these cases.
When you do replace, matching a 15-year-old granite to a new slab is hard, so it is often a whole-kitchen decision. Our granite countertops page covers choosing a new stone.
We price each granite repair after seeing the damage, in photos or in person. These are the factors that drive it.

Usually not. Most cracks in granite countertops are cosmetic and stay stable once they are filled. A crack is a structural concern when one side has dropped, the crack keeps growing, or the cabinet underneath has shifted, and in that case the support needs fixing first.
It depends on the size of the chip, where it is on the edge, and how hard your granite is to color match. Fixing several chips in one visit lowers the cost per chip. Email photos to info@topstonegranite.com and we can tell you what the repair involves.
Yes, for the repaired area at least. Cleaning and polishing during the repair strips any existing sealer around the spot, so we reseal it to keep oil and water out. If the rest of the top fails a water test, our stone sealing service covers the full surface.
Yes. We remove the old filler, pull the pieces level with a seam setter, and refill the joint with color-matched epoxy. If the cabinet below is moving, we point that out so the seam does not open again.
Email photos of the chip, crack or seam to info@topstonegranite.com, or call to set up a visit. We will tell you how well the repair should blend before we start.
