Jefferson Market Library

The Jefferson Market Branch of the New York Public Library was designed by Frederick Clark Withers and Calvert Vaux and completed in 1877.

Thaw was convicted of the murder of Stanford White at the courthouse. More recently, Joan Berkowitz specified D/2 for exterior stone and masonry cleaning in 2010.

Old San Juan

The city walls of San Juan, Puerto Rico are a part of the San Juan World Heritage Site. The walls were begun in the 1630s with construction continuing for the next 150 years. They average 42 feet in height and are also about 42 feet thick at their base. The National Park Service began cleaning the walls with D/2 Biological Solution more than 8 years ago.  The current project includes two distinct sections of the wall known as the Santa Elena and the San Augustin. Together they extend 2,600 feet. The Atlanta office of architects Lord Aeck Sargent have been retained by the NPS to write the cleaning specifications.

Pope-Leighey House

In 1939 journalist Loren Pope and his wife Charlotte Pope commissioned Frank Lloyd Wright to design a new home. The design followed Wright's Usonian principles and was completed in 1941. The "Usonian" house was developed by Wright as a means of providing affordable housing for people of moderate means. Wright employed wood cladding as an affordable and easily workable material into his design. After almost a century, the wood cladding needed some help. That's where D/2 came to the rescue. D/2 is often used to control biological growth on wood subject to moisture and was used here to remove bio growth without harming the sensative historic fabric of this Wright gem.
