Brick
Historic Concrete
Ceramic Tile
Decorative Plaster

Brick is so common a building material as to be easily overlooked in the survey of historic building materials, but it is so ubiquitous that to ignore it would be misleading. The following brick restoration and repair projects are representative of the issues we face when dealing with this widely used material.

With the commercial advent of modern day Portland cement, the use of concrete in construction blossomed and grew to large quantities by the early part of the 20th Century. The projects listed here provide a good sampling of historic concrete restoration, patching, and repair jobs.

Ceramic and marble tiles have been around for a long time, and their use in mosaic surfaces has always been an enjoyable challenge from a restoration viewpoint. With the advent and dispersal of porcelain technology, these durable materials became a regular component in historic structures.

Decorative plaster is a versatile medium that poses its own set of challenges but can yield highly decorative and enriched interior building surfaces. The decorative and ornamental plaster restoration projects shown here were the result of seismic upgrades and historic tax credit requirements..

Cast Stone
Terra Cotta
Mosaic Tile
Natural Stone Restoration

Cast Stone (sometimes labled 'PreCast') is the cost-effective substitute for hand-carved natural stone developed at the beginning of the 20th c. As Portland cement became more available towards the end of the 19th century, its use as an alternative decorative building material became more prevalent. Given California's major surviving buildings date from after 1900, there are multiple examples of cast stone restoration and repair projects.

Terra cotta, both glazed and unglazed, is a very common decorative building material, used widely from its commercial introduction in the late 19th century until today. Originally marketed as a cost-effective alternative to hand-cut natural stone, it has evolved into a medium all its own. The following terra cotta restoration projects involved the use of repair as well as complete terra cotta replacement to provide the finished results.

Ceramic and marble tiles have been around for a long time, and their use in mosaic surfaces has always been an enjoyable challenge from a restoration viewpoint. With the advent and dispersal of porcelain technology in the last two centuries, these useful and durable materials became a regular component of many historic structures. Ceramic tile and mosaic restoration projects vary widely.

Natural stone as an exterior building material is not as prevalent on the West Coast as it is in the Eastern States, only because the majority of our buildng cycles took place after the advent of Portland cement and ceramic building materials. However, there are enough instances of natural stone in the urban Western environment to address this material, especially in regards to interior surfaces.

Client Projects

Seismic Retrofitting of Historic Masonry
Since so many historic buildings in California failed to realize the architectural implications of earthquakes, many of our projects involve seismic retrofitting. This often requires careful selective removal of original masonry in order to allow for strengthening of the building's framework. Steel connections are introduced for structural stability. The following projects illustrate the demanding procedures involved in seismic upgrades, and the care needed to disassemble a masonry building and put it back together after retrofitting is complete.

Natural Stone Restoration, Repair, and Replacement
Natural stone as an exterior building material is not as prevalent on the West Coast as it is in the Eastern States, only because the majority of our buildng cycles took place after the advent of Portland cement and ceramic building materials. However, there are enough instances of natural stone in the urban Western environment to address this material, especially in regards to interior surfaces. The following stone restoration projects give some idea of how we have dealt with the medium in our restoration work.

Restoration and Repair of Historic Cast Stone and Decorative Trim
Cast Stone (sometimes labled 'PreCast') is the cost-effective substitute for hand-carved natural stone developed at the beginning of the 20th c. As Portland cement became more available towards the end of the 19th century, its use as an alternative decorative building material became more prevalent. Given California's major surviving buildings date from after 1900, it is no surprise that there are multiple examples of cast stone restoration and repair projects for our review.

Historic Concrete Restoration & Repair
With the commercial advent of modern day Portland cement, the use of concrete in construction blossomed and grew to large quantities by the early part of the 20th Century. The projects listed here provide a good sampling of historic concrete restoration, patching, and repair jobs, illustrating the use of concrete in historic buildings and facades.

Historic Masonry Cleaning Solutions
The cleaning of historic masonry is one of the most important aspects of a restoration project. Simple cleaning can make the difference in the overall impression of a project, regardless of any structural or sub-surface issues that may have been sucessfully resolved. This review of historic masonry cleaning covers the most common means and methods, including both chemical and mechanical techniques, some old and well-known, and some newer methods that are less familiar.

Historic Terra Cotta Restoration, Replacement and Repair
Terra cotta, both glazed and unglazed, is a very common decorative building material, used widely from its commercial introduction in the late 19th century until today. Originally marketed as a cost-effective alternative to hand-cut natural stone, it has evolved into a medium all its own. The following terra cotta restoration projects involved the use of repair as well as complete terra cotta replacement to provide the finished results. The restoration of terra cotta veneers often involves patching and repair of glazed decorative surfaces, using specialty patching mortars and coatings. Structural and surface damage can originate from moisture penetration behind the terra cotta units, so waterproofing and anchorage issues must be addressed as well.

Historic Brick Restoration
Brick is so common a building material as to be easily overlooked in the survey of historic building materials, but it is so ubiquitous that to ignore it would be misleading. The following brick restoration and repair projects are representative of the issues we face when dealing with this widely used material.

Tile and Mosaic Restoration of Historic Structures
Ceramic and marble tiles have been around for a long time, and their use in mosaic surfaces has always been an enjoyable challenge from a restoration viewpoint. With the advent and dispersal of porcelain technology in the last two centuries, these useful and durable materials became a regular component of many historic structures. The following ceramic tile and mosaic restoration projects give some indication of how varied these materials can be.

Restoring Historic Decorative Plaster Surfaces
Decorative plaster is a versatile medium that poses its own set of challenges but can yield highly decorative and enriched interior building surfaces. The decorative and ornamental plaster restoration projects shown here were the result of seismic upgrades and historic tax credit requirements regarding the amount of original material reinstalled.
