JTI is a three-generation family-owned company that has specialized in restoring historic buildings for more than 50 years, with much of its work focused on flat and ornamental plaster.
While JTI continually pushes the envelope for new ways to improve restoration and conservation techniques, the company is also proud of its enduring technological developments such as its proprietary telescopic lifts that enable the repair of damaged plaster without the intrusive and expensive use of scaffolding.
Now headed by Ray Tiedemann, who grew up in the liturgical plastering and painting trade with his father and uncles, JTI has expanded its scope to include national historic site preservation work.
In the process, JTI has put together a talented staff of designers, plasterers, painters, faux finishers, artisans and fine artists who bring experience, skill and passion to every job we undertake.
