The initial photographs document the garage laundry setup, the foil transition hose and wall connection, and a roof termination screen heavily packed with fibrous lint. Hygienic Air staged service air lines, accessed the roof termination, and removed the obstructing screen together with the captured lint. This directly addressed the photographed restriction and removed combustible buildup from the outlet. Later views show the termination without the trapping screen, with the metal damper and persistent staining visible. The photographs document the correction and the clearer accessible outlet without claiming measured airflow or confirming free damper movement.
