Graciano Corporation has been restoring stone facades throughout New York City for generations. The city's neighborhoods are defined in large part by their stone buildings -- the brownstones of Park Slope, Brooklyn Heights, and Harlem; the limestone-clad apartment buildings of the Upper West and East Sides; the granite and marble civic structures of lower Manhattan; the sandstone row houses of Carroll Gardens and Cobble Hill. Each material type, each neighborhood, and each period of construction presents its own restoration challenges. Our team brings the material knowledge and hands-on experience required to address them correctly.
Brownstone and Pre-War Stone in NYC
New York City's brownstone row houses represent one of the most distinctive and beloved aspects of the city's built environment. The brownstone neighborhoods of Brooklyn -- Park Slope, Brooklyn Heights, Boerum Hill, Fort Greene, Carroll Gardens -- and Manhattan's Harlem and Hamilton Heights are among the most intact 19th-century residential streetscapes in the country. Brownstone itself, a soft New Jersey sandstone that was quarried and shipped to New York in vast quantities in the second half of the 19th century, is a relatively fragile material that requires careful handling. Aggressive cleaning methods, incompatible repair mortars, or inappropriate patching materials can cause damage that is worse than the original deterioration. Proper brownstone restoration requires understanding the material and the appropriate repair methods for its specific characteristics.
Landmark District Considerations
Large portions of the neighborhoods where brownstone and historic limestone buildings are concentrated are regulated by the NYC Landmarks Preservation Commission (LPC). Stone repair and restoration work on individually designated landmarks or buildings within historic districts must comply with LPC guidelines and may require permit approval before work can proceed. Graciano's team is familiar with LPC requirements for stone restoration and can coordinate the permitting process as part of the project scope.
