Brownstone, Limestone & Granite Repairs
Preserving NYC’s Architectural Strength and Beauty
New York City’s architecture is defined by its stone façades—from historic brownstone row houses in Brooklyn to limestone-clad landmark structures and granite commercial buildings in Manhattan. These natural stones, while durable, are constantly exposed to weather cycles, pollution, and water infiltration, leading to cracks, spalling, erosion, and staining over time.
At MGR Restoration, we specialize in brownstone, limestone, and granite repairs that restore both aesthetic beauty and structural performance, ensuring compliance with NYC codes and preserving the city’s architectural heritage.

Understanding Stone Deterioration and Why Repairs Are Essential
Each stone type presents unique challenges that require specialized repair techniques:
- Brownstone – Known for its warm, earthy tones, brownstone is highly porous. Over
time, water infiltration causes surface flaking (spalling), cracks, and deep erosion,
weakening both appearance and strength. - Limestone – A softer stone that weathers quickly in NYC’s harsh climate. Acid rain,
pollutants, and freeze-thaw cycles often lead to surface loss, pitting, and discoloration. - Granite – Hard and durable, but susceptible to staining, cracking, and joint failure. Once damaged, repairs require precise cutting and material matching.
If left untreated, these issues can escalate into structural instability, water leaks, and Local Law 11 violations. Timely repairs not only protect safety but also extend the life of the building envelope and preserve architectural character.
