Restoration masons are stone specialists. They prepare mortars, cut out and fill joints, reset copings, and clean stone surfaces. They can drill, grout, and pin fractured stones. They work with brick, stone, and terra cotta blocks in ashlar, rubble, and brickwork. Specialized restoration masons may restore damaged chimneys and foundations in heritage buildings or repair crumbling monuments.
Brick and stone masons construct and repair structures. They may work on walls, arches, paving, floors, fireplaces, chimneys, and smokestacks. Masons can specialize in high-temperature materials, such as fire brick, which are used for industrial furnaces, retorts, and boilers.
Refractory masons protect structures from high heat by installing special refractory bricks, castables, blankets, plastics, or ceramic coatings to furnaces and kilns. They must be skilled at laying refractory bricks, installing castables, and removing old refractory masonry. This is a specialty trade for those who are certified as brick and stone masons.
