A closer look at our recent restoration work at the historic Landmark Theatre in Syracuse, NY.

This album showcases the craftsmanship, detail, and care behind John Tiedemann Inc.’s work throughout this remarkable interior. From plaster restoration and decorative finishes to ornate architectural details, each image reflects the precision required to preserve spaces of this scale and significance.

Historic restoration is more than repairing what is damaged it is protecting the artistry, character, and legacy of a space so it can continue to be experienced for generations to come.

From plaster restoration to decorative finishes, this is what we do.

Inside the historic Woolworth Building, John Tiedemann Inc & HPCS. Preserve and relocate a remarkable coffered plaster ceiling originally from Mr. Woolworth’s private office. The ceiling was carefully dismantled piece by piece, restored, and reinstalled in the residence's entrance lobby, allowing this historic craftsmanship to continue being seen and appreciated for generations to come.

Our work is rooted in preservation, precision, and respect for the architectural details that make historic spaces unforgettable.
