Masonry repair is a major part of building restoration. It includes pointing, brick and parapet reconstruction, and may also include specially-designed anchors for brick, color matching of brick, and staining of stones.

When a building's façade is exposed to weather, the freeze and thaw cycle can have a detrimental impact on the masonry of a building—both brick and block. AM&G Waterproofing expertise addresses the problems that may arise, including the reconstruction of parapets, the removal and resetting of coping stones, the modification and restoration of deteriorated structural steel, waterproofing of lentils and window jams, the replacement of deteriorated window sills, and the installation of face-mounted or through-wall flashings on parapet walls—all of which requires masonary expertise.

For our repointing work, AM&G uses tools that are equipped with vacuums to minimize the dust. We also do façade brick replacement, and clear waterproofing repellent application.

At AM&G both large and small jobs get the same attention to detail our customers have come to expect.

AT&T Plaza, 33 Thomas Street
AM&G takes particular pride in our stone restoration. In over two decades of experience in New York City, we've encountered and restored pre-cast concrete, terracotta, GFRC (Fiberglass), limestone, marble, granite, and more.  Each of these materials requires a different type of treatment and approach.

AM&G has a long list of suppliers with whom we've worked for many years, and who supply us with high quality materials. Some of the elements and trim pieces we restore are quoins, cornices, urns, scrolls, stone bases, gargoyles, and window jams — the architectural features of a building that gives it definition and character. High quality is essential when it comes to these architectural elements because they are often the most noticible aspect of a building. We make sure they stand out properly, the way the architect originally intended.

The anchoring systems for stones can be very elaborate; the stone must stay in place. AM&G can fabricate anchoring systems and shapes necessary for all types of stones.  Like New York's buildings, each stone and system is unique, and we understand the engineering issues involved in all aspects of custom stonework.

Stone Glossary:

Terracotta is a durable and waterproof ceramic material made from baked clay. Its reddish-brown color comes from the natural iron content in clay. Terracotta is used in everything from bricks and shingles, to decorative elements and ornament on buildings. It's been a preferred material since ancient times by cultures around the world.

Precast Concrete
Unlike sidewalks or floors which are poured in place, precast concrete has been cast into form before being used in position. Precast concrete can be used to form many architectural features, from walls and panels, to pipes, tunnels and safety barriers. Precast concrete is extremely strong and requires minimal maintenance.

GFRC stand for Glass Fiber Reinforced Concrete, and as the name implies, is a cementitious mixture reinforced with glass fibers, as well as high-performance polymers and other additives. GFRC is a superior construction material in that it offers a natural stone appearance, while being extremely strong, light, and moldable. GFRC can be formed into almost any shape—ornamental or structural. Significantly lighter than concrete, GFRC is used often in architectural detail and ornament.

Granite is a type of rock formed from molten rock which has been cooled over millennia. A coarse-grained, crystalline igneous rock, granite has a rough, crusty surface and a rich coloration that varies depending on the percentages of different minerals in the particular granite. As a construction material, granite is used in many ways, from rough-hewn blocks, to highly polished, decorative tiles and surfaces.

Marble is what is known as a "metamorphic rock". It is mostly limestone rock that has undergone a chemical change from pressure or heat. Long considered an elegant and desirable material, it is is characterized by streaks or veins of color, and an ability to take to a highly polished finish. The color in marble is due to chemical impurities from a variety of minerals, and marble itself comes in a wide range of colors.

Limestone is derived from sedimentary rocks made, for the most part, from the mineral calcite in leftover marine organisms deposited on the floors of evaporated seas and lakes. Limestone has been a very popular building material in North America and Europe for centuries, and is the primary source of lime for cements. Limestone is particularly vulnerable to acid rain and weather conditions.
