Craftwork Training Center Provides TLC for Historic Wood Windows!

Whether you’re an owner, contractor, craftsman, architect, or someone who simply loves old windows, join us for a 4-day workshop to rehabilitate vintage wood windows. Instead of giving up on your old windows, practice hands-on restoration techniques with nationally recognized preservationist Duffy Hoffman.

  • Take a wood window sash through the restoration process–from start to finish.
  • Map and number windows prior to removal.
  • Disassemble, stabilize, and reassemble window units.
  • Repair or replace window chains or ropes.
  • Restore, spice, or replace deteriorated and missing members.
  • Review paint-stripping materials and methods and routine maintenance.
  • Use a duty-specific steam box to safely remove old paint and glaze.
  • Reglaze windows and replace broken or damaged glass.
  • Brush up on painting and refinishing tools, techniques, and materials.
  • Incorporate lead-safe work practices (RRP certification included).

To ensure an exceptional learning experience, the class size is limited. Book Workshop JOYN-01 (July 24-27, 2017) online today at or call 215-536-1776 to register by phone.
