Window Installation Inspections — Flow State Drones
Verifying the condition of windows, frames, seals, and surrounding masonry at height has traditionally required expensive scaffolding or cherry pickers. Drone inspection removes that cost entirely. Our high-resolution cameras capture close-up aerial footage of every window and glazing element across all elevations — identifying installation defects, sealant failure, cracked or misted glazing units, damaged frames, and water ingress points. All inspection reports include annotated photographs and clear written observations, formatted for homeowners, installers, property managers, and insurers.
