Historic Marble
Marble floors, staircases, fireplaces, wainscoting, and architectural elements in buildings from the 18th through mid-20th century. We restore historic marble using diamond techniques that preserve original profiles, edges, and surface character. We do not over-polish or modernize historic finishes — we return them to their intended appearance. Marble services →
Historic Terrazzo
Mid-century terrazzo floors in schools, government buildings, post offices, courthouses, and public buildings. We strip accumulated wax layers, repair cracks with lab-matched aggregate and resin, and restore the diamond polish that these floors originally had. Terrazzo services →
Historic Masonry
Brick and stone facades, chimneys, arches, columns, steps, and walls in historic buildings. Historic masonry requires lime-based mortar — not Portland cement — because the softer mortar is compatible with the softer historic brick. Portland cement repointing on historic brick is one of the most common and destructive mistakes in building maintenance. Masonry services →
Historic Limestone and Sandstone
Facades, decorative elements, window surrounds, cornices, and columns. These soft stones require gentle cleaning methods and breathable sealers. We never use high-pressure washing or acid cleaning on historic limestone. Facade cleaning →
Historic Metal
Bronze plaques, brass railings, copper elements, and decorative metalwork. We restore historic metal finishes to their original appearance — polished, patinated, or lacquered as appropriate to the period and the building. Metal services →
