High-profile failures—like the ceiling collapse at Apollo Theatre or a fallen rosette in Rose Main Reading Room—underscore the importance of maintaining plasterwork. Plaster has been used for centuries in both flat applications and ornate decoration, but it is inherently vulnerable to environmental and structural stress. Without proper care, it can crack, detach, or fail.

Effective plaster conservation begins with a thorough survey of both the plaster and the structure behind it. EverGreen’s plaster specialists often collaborate with structural engineers to diagnose causes and define targeted stabilization, conservation, and repair strategies. More in depth investigation, testing, and analysis of the exact plaster composition and historic finishes is commonly involved for replicating the visual and aesthetic properties of the original plaster and decorative art.

When preservation standards apply, interventions are kept minimal, prioritizing retention of original material and ongoing monitoring over invasive work. If elements are lost, they can be accurately recreated using historical documentation and material analysis to match original composition and finishes. Each project concludes with a detailed report and preservation plan outlining condition, risks, and recommended actions.
