Across America, there are literally thousands of historic buildings with ornate plaster ceilings of enormous cultural and aesthetic value.
John Tiedemann Incorporated (JTI) and Historic Plaster Conservation Services (HPCS) have invented and developed a range of specialized tools and methods for the conservation of these important and delicate plaster structures.
Using a combination of traditional and innovative systems and tools, our talented staff of designers, plasterers, painters, faux finishers, artisans and fine artists bring decades of experience, skill and passion to every job we undertake.
