Cornice Repair Explained for NYC Buildings
Cornice repair is the work of securing, repairing, and restoring the projecting cornice that crowns the top of a building’s facade. In New York City, a huge number of cornices on late nineteenth and early twentieth century buildings are made of galvanized sheet metal, formed and painted to look like carved stone, while others are stone, terra cotta, or occasionally wood. Because a cornice sticks out over the sidewalk at the very top of the building, it takes the worst of the weather, and when water gets in through its top or seams, the metal rusts, the supports inside weaken, and the whole cornice can start to sag or pull away from the wall. Good cornice repair fixes that support system, stops the water from getting in, and keeps the profile that gives the building its character.

Cornice Repair Permits, Landmarks, and Safety in NYC
Cornice work happens high above the sidewalk and often on landmarked buildings, so approvals and protection are part of the plan.

Cornice Repair FAQs
Many cornices on older NYC buildings are galvanized sheet metal, shaped and painted to look like stone. Others are carved stone, terra cotta, or on some older row houses, wood. The material decides how the cornice fails and how it should be repaired.
Often, yes. If the cornice itself is mostly sound, its supports can be rebuilt and it can be re-anchored to the wall. When large sections have rusted or rotted through, those sections are replaced with new pieces matched to the original profile.
It can be very dangerous. A cornice hangs over the sidewalk at the top of the building, so loose pieces can fall a long way. Loose cornices are often classified as Unsafe in FISP reports and need protection and repair right away. See our unsafe facade repair page.
On landmarked buildings, removal is generally not allowed without LPC approval, and a replica is usually expected. On other buildings, removal is possible but changes the look of the building and still requires proper finishing of the wall and any needed permits. In most cases, repair or replication preserves both safety and value.
It's a new cornice section made to match the original shape, often from metal, fiberglass, or glass fiber reinforced concrete. Replicas are lighter than stone and don't rust like old metal. On landmarked buildings, the material and design need LPC approval.
Keep it painted, keep the cap flashing on top sealed, and have its fasteners and supports checked regularly. Unlike masonry, sheet metal needs paint to protect it from rust.
Scaffolding and sidewalk sheds over the sidewalk need DOB permits, landmarked buildings need LPC approval, and larger changes such as removal or full replacement can need additional approvals. We confirm what your job needs before quoting.
