Our approach to Architectural Conservation combines science, craft, and advanced technology to carefully assess, analyze, and repair architectural material using sustainable practices. We combine assessment and treatment to preserve the original material and construction techniques. Our work is performed on-site or in our conservator’s labs.



HCG Object Conservation focuses on maintaining the integrity and authenticity of an object. We take a least possible intervention approach and use reversible techniques to support an object long-term conservation. Long-term preservation of important cultural objects is the goal of HTC conservators. Our approach may range from general observations to specific treatment applications and routine annual maintenance procedures.





Our Paper Conservation services include the stabilization and treatment of drawings, prints, architectural drawings, letters, and other documents on paper from various ages. HCG uses quality materials and techniques tailoring our conservation approach to the individual work.
