John Tiedemann Inc

JTI is a family-owned company that has been dedicated to restoring historic buildings for over 70 years, spanning three generations. Our primary focus is on flat and ornamental plaster restoration. We are continually seeking innovative methods to improve our restoration and conservation techniques. At the same time, we take pride in our technological advancements, including our proprietary telescopic lifts, which allow us to repair damaged plaster without the need for intrusive and costly scaffolding. Now led by Ray Tiedemann, who has a deep-rooted background in the liturgical plastering and painting trade, working alongside his father and uncles, JTI has broadened its scope to include the preservation of national historic sites. Throughout this journey, we have assembled a talented team of designers, plasterers, painters, faux finishers, artisans, and fine artists. Each member brings a wealth of experience, skill, and passion to every project we undertake.
