Certified Window Repair Technician (NGA) The NGA exam demands you diagnose real-world window failures—from thermal seal breakdown to frame rot—and execute repairs under time constraints. You’ll troubleshoot glazing compound adhesion problems, replace weatherstripping correctly, and demonstrate proper caulking techniques. This isn’t theoretical; evaluators watch your actual technique on materials you’ll encounter on job sites daily.
