Masonry Restoration

Masonry restoration is the art of bringing an existing masonry structure back to its original condition and/or form. The primary techniques utilized in masonry restoration are chemical cleaning, rebuilding, replacement and/or tuckpointing. Restoration includes projects such as tuckpointing a chimney to restoring the entire terra cotta façade on a hundred-year-old building.

Cleaning

The process of chemical cleaning involves removing stains and pollutants from the surface of brick, granite or stone masonry. Specially formulated chemicals are sprayed and brushed onto the masonry surface. The chemicals are then rinsed off with high-pressure water.

Rebuilding

Rebuilding in masonry restoration is the process of taking down an existing section of masonry and rebuilding the structure utilizing either new or salvaged materials. The decision to incorporate either new or existing materials is based on the integrity of the old materials.

Replacement

Replacement in masonry restoration is a process by which cracked, broken and/or spalled masonry is removed and replaced with a masonry unit matched in color and texture to the original masonry unit being replaced.

Repairing

The process of repairing a mortar joint in a masonry wall is called “tuckpointing.” Tuckpointing consist of grinding out mortar joints to a depth of approx. ¾” using electrical grinders and hand chisels. Once removed the mortar joints are brushed and rinsed clean and two compacted layers of Type N mortar applied. The mortar joints are then tooled to match the existing mortar joints on the structure.
