Graciano Corporation has been cleaning masonry facades in New York City for decades. The city's dense urban environment deposits soot, grime, biological growth, and atmospheric pollutants on building exteriors at a rate that dramatically affects building appearance and, over time, can contribute to material deterioration. Our masonry cleaning services are tailored to the substrate, the soiling conditions, and any applicable landmark or historic preservation requirements.
NYC Masonry Cleaning Challenges
New York City buildings present a range of cleaning challenges that require genuine expertise. Decades of urban pollution have deposited heavy carbon soot and particulate matter on limestone, granite, brownstone, brick, and terra cotta surfaces throughout Manhattan, Brooklyn, and the Bronx. Pre-war buildings in particular can have a century or more of accumulated grime that must be addressed carefully -- aggressive cleaning methods that are safe for modern concrete can cause severe, irreversible damage to soft limestone and historic brick. Understanding material composition and soiling type is the prerequisite for selecting the right cleaning approach.

Historic and Landmark Considerations
New York City has the most extensive landmark preservation program in the United States. Thousands of individual buildings and dozens of historic districts are regulated by the Landmarks Preservation Commission (LPC). For buildings within landmark districts -- including large areas of Brooklyn Heights, the Upper West Side, Harlem, Chelsea, and many more neighborhoods -- cleaning methods must be compatible with LPC guidelines and may require permit approval. Graciano's team is experienced in the requirements of landmark cleaning projects and coordinates with the LPC process as needed.
