GMW has mechanics trained in techniques for historic preservation and restoration of period masonry structures, specifically pointing, also known as tuck pointing, and brick replacement or reconstruction. Our skilled brick masons can reproduce historic mortar joint finishes in durable original lime mortars. Whether stone, brick, terra cotta or even glass, we endeavor to introduce matching repairs into the structure which will disappear seamlessly into the original work. All our employees are charged with understanding materials and maintaining the highest standard of craftsmanship. Our high standards mean extended performance and more value for our clients. These standards are most critical for historic re-pointing, unit replacement and masonry reconstruction projects.

GMW  furnishes building stone restoration services to the field. Our services include replacement of damaged stone units with reproduction elements in the original historic material, whether brownstone, limestone, sandstone, granite marble or any other building stone, or fabrication of cast replications of original work, taken from molds developed from the existing elements. Where units are only partially damaged, we can introduce stone "dutchmen", partial replacements fabricated from the original stone and epoxied into place or patch the damaged area with stone patching material, cast or tooled into place. We use the ®Jahn stone patching system. Stone restoration requires a comprehensive mix of skills for stone replacement, stone patching and stone repair by craftsmen who understand the requirements of these historic materials.
