Leeds Clark Inc. believes inspection of the historic windows and its materials is vital in developing a historic window restoration/replication plan. Condition assessment of the historic windows helps the architect and building owner/s establish needs, offer realistic solutions and specifications, then develop a plan and budget to determine feasibility of the proposed historic window restoration/replication project. Leeds Clark, Inc. has completed hundreds of historic window restoration/replication projects across the country throughout 40+ years in business. Learning from each and every historic window restoration/replication project, Tom Clark and his company have developed and tested a  historic window restoration methodology based on material type: wood, steel, galvanized & hollow metal.

Following the Secretary of the Interior's "Standards for Rehabilitation", Leeds Clark, Inc. has developed a turn-key historic window restoration/replication service based on tested and proven methodologies and restoration products. Tom Clark and his company have worked close over the years with the National Park Service on historic window preservation and restoration techniques.  On a couple of occasions, Tom Clark has met with John H. Myers, author of Preservation Brief 9,  to discuss the proper restoration and replication techniques of historic wood and steel windows.
