Andy deGruchy is the owner of LimeWorks.us, the nation’s leading manufacturer and distributor of “green” historic preservation and sustainable building mortars, plasters and paints based on lime and not Portland cement. His lime-based materials are used for durable, appropriate, time-tested historic masonry restoration campaigns. Due to the correlation between a lower embodied energy in production to final recycling of the limes, Andy also distributes these exceptional life-cycle materials for sustainable building systems which yield substantial CO2 credits.

In 1979, Andy received a full scholarship for a three-year program to study and practice masonry from the nation’s oldest private, post secondary, free trade school, (Then named) The Williamson Free School of Mechanical Trades, (Now called) Williamson College of the Trades in Media, PA. founded in 1888. He received their “Key” award for the advancement of its founding ideals. He maintains a few specialty crews which have operated through the past 34 years as deGruchy Masonry Restoration. deGruchy has restored hundreds of historic buildings in the Delaware and Lehigh Valleys of Pennsylvania. Andy holds lectures and training workshops on the subject of historic masonry restoration and sustainable building. Andy is active in promoting volunteerism to educate about and protect our American Institution which includes our natural and built environments. He finds that working to preserve our cultural resources as they are found and interpreted through regional vintage architecture, including our nation’s historical burial grounds, is his life’s work and his best area of service to the conservation industry.
LimeWorks.us was started out of necessity to better serve the historic buildings that our sister company deGruchy Masonry Restoration has been commissioned to restore. In 1999 LimeWorks.us started to import Natural Hydraulic Lime products from St. Astier, France. St. Astier has been quarrying the same deposit of limestone for more than 165 years. Our import makes this lime more readily available for use on buildings in the United States such as St. Patrick’s Cathedral, New York and the Rotunda Dome at the University of Viriginia. Our company has grown to supply associated tools, training,and qualified consultation to effectively raise the bar in historic preservation and sustainable building.
