Deep grout cleaning, regrouting, grout color restoration and grout repair for NYC restaurants, retail stores, offices, and homes. Make stained, cracked grout look new again.
From stained restaurant floors to cracked bathroom grout — we restore grout to like-new condition.
High-pressure steam and professional cleaning agents dissolve grease, food residue, mold, and years of buildup. Used by NYC restaurants and commercial kitchens.
Shower regrouting and full tile regrouting — we remove deteriorated grout and install fresh grout. Eliminates cracked, crumbling, and missing grout lines that cause water infiltration.
Professional grout color sealing restores faded, discolored grout to a uniform color and seals it in one step. Looks like new grout without removing and replacing it.
Penetrating sealer applied after cleaning or regrouting. Protects against future staining, moisture absorption, and mold growth.
Repair cracked, missing, or damaged grout in specific areas. Matched to existing grout color for seamless repair.
Upgrade to commercial-grade epoxy grout — virtually stain-proof, chemical-resistant, and rated for heavy commercial use.
Stained, black, cracked grout is costing you customers and health inspection points. We restore it — on your schedule, nights and weekends.
Under the NYC Health Code, floors — and the materials used to repair them — in food prep, storage, warewashing, walk-in and restroom areas must be hard, smooth, durable, non-absorbent and easily cleanable, and kept free of cracks, holes and gaps at floor-and-wall junctions and around plumbing. Open, crumbling or missing grout is exactly the condition that fails that standard. We regrout NYC commercial kitchens so the floor holds up to inspection — working overnight so you never lose a service.
Quarry tile is the NYC kitchen standard and it holds up for decades — the grout is what fails first. We cut out deteriorated joints and regrout with epoxy grout, which is non-absorbent, chemical-resistant and stands up to daily degreasing and hot washdown.
Prep areas, bars, dish stations, walk-ins and restrooms often use subway, hex or mosaic tile with far more grout line per square foot — which means far more places for grease and moisture to get in. We regrout all of it, walls included.
The floor-to-wall junction and the gaps around floor drains and plumbing penetrations are where inspectors look hardest. We seal coved bases, drain surrounds and pipe penetrations so there are no unintended openings left behind.
We start after last service and hand the kitchen back before morning prep. Fully insured, COI issued to your landlord or property manager before we set foot on site — standard for Manhattan buildings.
Re-inspection coming up, or a violation to correct? Call (332) 277-0990 — we walk the kitchen, tell you what will and won’t pass, and schedule around your service.
Faded, patchy or permanently stained grout doesn’t always need replacing. Grout color sealing restores a uniform color and seals the grout in a single application — at a fraction of the cost and mess of full regrouting.
A pigmented sealer is bonded into the grout line, giving every joint one consistent color and forming a protective barrier against water, grease and staining. It works on floors, showers, backsplashes and commercial kitchens.
Regrouting removes and replaces the grout — the right call when grout is cracked, crumbling or missing. Grout color sealing is for grout that is structurally sound but discolored. We tell you honestly which one your tile actually needs.
We match your existing grout color, or change it entirely — light grout darkened to hide traffic staining is one of the most requested jobs in NYC apartments and restaurants.
A properly applied grout color seal typically holds for several years in a residential bathroom and is re-applied more often in high-traffic commercial floors. Cleaning gets easier immediately — sealed grout resists absorbing spills.
Most grout color sealing jobs are completed in a single visit with no demolition and no dust. We work residential bathrooms and kitchens across Brooklyn, Manhattan, Queens, the Bronx and Staten Island, and schedule restaurant and retail floors overnight so you never lose a service day.
We inspect all grout lines, identify problem areas: staining, cracks, missing grout, mold.

"Sani Building Corp restored the grout in our Brooklyn restaurant — floors, bathroom, and kitchen entry. The floor grout was black from years of grease. After their deep clean and regrouting, it looks like a brand new floor. They worked overnight and we were open for breakfast."
"They regrouted all the bathroom tile in our Sephora-style beauty store. The grout lines were so stained they looked terrible. Now the bathroom looks spotless and matches our store's aesthetic. Weekend work, no disruption."
"Had them clean and seal all the bathroom tile grout in our Brooklyn apartment. The grout went from dark grey to bright white in one visit. Easy process, showed up on time, and the result lasted much longer than I expected."
