Jeff Weiler & Associates has been engaged in pipe organ restoration, maintenance, voicing, and tonal finishing since 1983. The workshop, overlooking the Chicago River at 329 West 18th Street in Chicago’s South Loop district, is itself steeped in history having formerly served as a warehouse for the venerable department store, Carson, Pirie, Scott & Co. Using techniques often associated with the conservation of historic artifacts, five skilled artisans work to return voice and function to organ pipes and components. It would not be unusual to find us engaged in restoring a low-pressure mechanical action organ while at the same time the upper lips of a high-pressure Diaphonic Diapason are being releathered in another area of the workshop.
