Historic Brick, Stone, & Terra Cotta

When it comes to historic brick and stone masonry, the mortar utilized is equally important to the integrity of the structure. Our team will test and analyze the mortar used as well as the cause of the deterioration in the stone, terra cotta, or brick, and educate the customer of these causes and determine solutions. Historic materials, specifically mortar and brick from pre 1930 are vastly different than modern materials and necessitate specific knowledge to repair correctly and not cause greater deterioration.

Historic Coatings

Many historic structures feature historic coatings. These range from lead paint, oil paint, mineral coatings, thermoseal and/or modern paints. While some coatings can be historically appropriate for the building, sometimes they are the main reason for deterioration and need to be remediated.

Historic Hardscapes

When it comes to historic stonework and masonry details, appropriate restoration methods and materials can make the difference between a seamless repair and one that stands out more than the original deterioration. Our team properly utilizes many methods of patching and repairing historic stones which brings the uniqueness of the structure’s details back to its prime.

Historic Plaster

While the techniques for historic plaster application are remembered by few, our team of artisans ensures the techniques live on well into the future, by having mastered and utilizing the three-coat lime plaster that was used almost exclusively until the end of the 19th century. This technique is unmatched in its historical appropriateness, strength and durability, and is incredibly fire and acoustic resistant.

Cemeteries & Monuments

By restoring cemeteries and monuments, our team takes on the role protecting and paying homage to the past as these monuments are a remembrance of a person, place, or significant event in history. Our team utilizes appropriate and accepted technologies and methods to clean and restore these memorials so that they may live on for decades to come.

Investigative Probes

A large part of working with historic structures is uncovering past repairs along with original construction methods and materials. This is typically undertaken utilizing “investigative probes” which are essentially researched locations in a building that are cut out, investigated, and documented thoroughly with material samples retrieved to be analyzed and catalogued.

Graffiti Removal

Graffiti is a common nuisance affecting historic buildings everywhere. Unfortunately, the graffiti itself can be less damaging than the actions taken to remove it. To prevent unnecessary damage, correct procedure must be followed in order to remove graffiti appropriately and safely.
