Fabricators Who Read the Stone Before They Cut It
Gunny Stone Repair & Installations does granite countertop repair, seam repair and blending, and countertop installation across San Antonio. The crew works on 3cm and 2cm slabs alike, matching veining and color before any epoxy fill goes near a seam.
San Antonio's housing stock runs the gamut, from older homes with original granite that's cracked or shifted at the seam to new-build kitchens getting quartz for the first time. Andre and the team have worked both ends of that spectrum, whether it's a misaligned seam that needs epoxy color matching to disappear or a full remodel that starts with digital templating and ends with a polished reveal on a waterfall edge. Homeowners searching for a fix after another contractor said a crack or a sink cutout couldn't be repaired tend to find their way here, and that's become part of the reputation locally, sometimes shorthanded as just calling Gunny Stone. That word-of-mouth comes from showing up when quoted, measuring twice before a bridge saw ever touches the slab, and cleaning up the site like the job never happened. Cooktop rough-in changes, undermount sink cutouts, marble restoration on older vanities, it's all treated with the same attention: check the substrate, confirm the mohs hardness of the material, then cut once. San Antonio, New Braunfels, and the surrounding Hill Country suburbs all fall inside the service area, and every job gets the same eye for seam blending whether it's a small chip repair or a full kitchen remodel's worth of stonework. Quotes are given upfront and the crew sticks to them, because a fair estimate only means something if the final invoice matches it.

Granite Countertop Repair
Gunny Stone Repair & Installations blends hairline cracks into aging granite slabs across San Antonio, matching color and vein pattern so the repair disappears into the stone. Many older San Antonio homes still run 3cm slabs from decades-old builds, and these thin fractures widen with heat and settling if left alone. We stabilize the stone before it spreads.
-
Quartz Countertop Repair
Gunny Stone Repair & Installations repairs chipped and cracked quartz countertops across San Antonio using color-matched resin fills that disappear into the slab's pattern. Engineered stone is non-porous and dense, so seam epoxy color matching has to be dialed in by eye before it cures. San Antonio kitchens with quartz islands and waterfall edges get the same close attention.
-
Marble Repair & Restoration
Gunny Stone Repair & Installations restores dulled, acid-etched marble in San Antonio kitchens and baths, removing water rings, wine etches, and cloudy spots without replacing the slab.

Common questions
What areas do you serve?
Gunny Stone works throughout San Antonio and out to New Braunfels, Schertz, Cibolo, Universal City, Converse, Live Oak, Boerne, Helotes, Leon Valley, Alamo Heights, and Seguin. If your address falls between those towns, call and ask, most nearby streets are covered.
How soon can you schedule a repair or installation?
Andre and the crew run appointments Monday through Friday from 8am to 7pm and Saturday 9am to 3pm. Simple crack or chip repairs often get booked within the week. Full fabrication and installation jobs need a template visit first, then typically a short lead time to cut the stone.
Do you handle emergency repairs, like a cracked sink cutout or broken cooktop rough-in?
Yes, within the same-day or next-day window when scheduling allows. A cracked seam near a sink or an undersized cooktop rough-in can turn into a bigger problem fast, so call and explain the situation. Gunny Stone prioritizes jobs that affect daily kitchen use.
What payment methods do you accept?
Gunny Stone accepts cash, check, and standard card payment for both repair and fabrication work.
Can you really make a crack repair invisible?
On granite and most quartz, color-matched epoxy fill and careful polishing can make a crack repair very hard to spot once cured, especially on stone with heavier veining or pattern to work with. Solid-color quartz and light marble show repairs a bit more. Andre will tell you honestly what result to expect before starting.
Do I need to replace my whole countertop, or can it be repaired?
Most cracks, chips, and separated seams can be repaired without replacing the slab, which saves money and downtime in the kitchen. Replacement makes sense if the stone has multiple structural cracks, heavy pitting, or you're changing layouts during a remodel. A quick in-person look tells you which route makes sense.
How long does a countertop installation take from template to finish?
Templating and rough-in measurements happen first, then the slab is fabricated off-site (cut, edged, and any cutouts for sinks or cooktops made) before install day. Simple installs finish in a single day once the stone is ready. Kitchen remodels with backsplash and multiple cutouts take a bit longer to sequence.
Do you seal granite and marble countertops?
Yes. Sealing protects porous stone like granite and especially marble from staining and etching, and it's worth doing on a regular schedule depending on how the stone is used. Gunny Stone can seal as a standalone service or fold it into any repair or fabrication job.
