Frame and hardware
Inspect profiles, connection points, base plates, braces, fasteners, and visible corrosion or deformation. Verify that the component set matches one identifiable system and that no improvised parts are carrying structural roles.
PVC, walls, and doors
Review cleaning condition, repairs, brittleness, staining, seam quality, panel dimensions, fastening details, clear sections, hard walls, and door interfaces. Confirm whether replacement panels can be supplied to the same dimensions and attachment method.
