Graciano Corporation provides specialized Guastavino tile repair and restoration services for New York City's extraordinary inventory of historic tile-vault structures. New York is home to some of the finest examples of Guastavino vaulting in the world -- spaces that are among the most recognized and visited in the country. Restoring these systems requires a combination of deep technical knowledge of Guastavino construction principles, careful material matching, and sensitivity to the architectural character that makes these spaces irreplaceable.
Guastavino Vaulting in New York City
The Guastavino company was extraordinarily prolific in New York City from the 1880s through the 1940s, and the city contains a remarkable concentration of their work. The Oyster Bar Restaurant at Grand Central Terminal is perhaps the most widely visited Guastavino interior in the world -- a vast vaulted ceiling of cream-colored tile that defines the character of the space. Ellis Island's Great Hall and Registry Room feature some of the largest Guastavino vaulted ceilings in the United States, recently restored as part of major preservation work on the island. The Cathedral of St. John the Divine, the undercroft and nave spaces of which incorporate extensive Guastavino tile systems, represents some of the most ambitious vaulting of the period. The Queensboro Bridge includes vaulted tile spaces in its anchorage structures. Dozens of subway stations, municipal buildings, libraries, hospitals, and academic buildings throughout the five boroughs incorporate Guastavino work at various scales.
What Makes Guastavino Systems Distinct
Guastavino tile vaults are structural -- the thin clay tiles carry loads through compression across the vault geometry, not through the bending resistance of individual elements. This means that repairs must be understood and executed in terms of the structural behavior of the system, not just the surface appearance. The mortar joint condition, the continuity of the tile laminations, and the connection between the tile system and its supporting structure all affect the structural performance of the vault. Using inappropriate repair materials -- modern Portland cement mortars, for example -- can introduce incompatible stiffness and moisture behavior that causes further damage to surrounding historic material.
Common Guastavino Deterioration Conditions
- Cracked or fractured tile units
- Loose or delaminating sections, identified by hollow sound on tapping
- Deteriorated mortar joints between tile units or layers
- Moisture staining, efflorescence, or biological growth
- Previous repairs using incompatible materials
- Joint and transition failures at connections to supporting structure
- Loss of glazed surface finish on ornamental units
