Intermediate Historic Wood Window Preservation & Repair



Canceled: Due to COVID-19, this course has been canceled, but will likely be offered in 2021.

Intermediate Preservation for Historic Wood Windows touches on much of the same material introduced in the Beginner Preservation for Wood Windows workshop, but with the addition of more intensive repair techniques and a greater emphasis on hands-on and shop skills. Trainees can still expect to learn building science foundations for preserving wood windows, documentation, reglazing, and finish options, but will spend a greater amount of time focusing on lead safety, joinery, dutchman repairs, and fabrication of rails, stiles, and muntins.

Working on site in the Historic Preservation Training Center’s shop in Frederick, Maryland, trainees will have the opportunity to work alongside HPTC craftspeople and learn from their extensive expertise working on window projects throughout the United States. Prior experience with historic wood window preservation is a prerequisite for this workshop.
