🪟 Historic Wood Window & Architectural Door Restoration

Original old-growth wood windows can last centuries when properly restored. Repair weight-and-pulley sashes and meet historic commission standards.

Why Authentic Methods Matter

Historic windows were crafted from dense, rot-resistant old-growth timber that is virtually impossible to replace with modern fast-grown lumber. Vinyl replacement windows typically fail within 10 to 15 years, cannot be repaired, and degrade the architectural character and appraisal value of historic homes. Furthermore, the Philadelphia Historical Commission and regional preservation districts strictly prohibit unapproved replacement inserts. Specialized window restorers rebuild original sash joinery, replace broken cords and chains, re-glaze glass with linseed oil putty, and integrate custom wood storm windows for modern thermal efficiency.

Standard Preservation Methods

  • Complete sash removal, paint stripping, and epoxy wood consolidation (Abatron)
  • Restoration of weight-and-pulley counterbalance systems, bronze chains, and sash cords
  • Traditional linseed oil glazing putty and preservation of wavy cylinder / historic glass
  • Custom-built exterior or interior wood storm windows for energy efficiency without aesthetic loss
