🔧 The Challenge
The historic government building's original wood windows were deteriorating, causing energy loss, water intrusion, and failing to meet security requirements. Replacement was prohibited due to historic preservation rules, requiring expert restoration instead.
💡 Our Solution
Auxi partnered with historic preservation specialists to restore original windows using period-appropriate techniques while adding concealed weatherstripping, security film, and storm panels. All work was reviewed and approved by the State Historic Preservation Office.
✅ The Outcome
All 312 windows restored to original appearance with modern security and energy improvements. Building maintained National Register status. Energy costs reduced 22%. Zero water intrusion incidents.
