Three kinds of example, each labeled honestly: documented public cleanups, our own project, and illustrative composites built from real patterns (not named people).
A documented extreme cleanup in which roughly a million pounds of accumulated material was removed from a single home, the far end of what a coordinated crew can bring back.
A half-century of accumulation cleared by a crew in four days, a working example of how fast an "impossible" space comes apart with a plan and enough hands.
Three offices, a server room swallowed by storage, a ham-radio loft, and cargo containers packed with high-end gear and paper from years of running a live show. Worked space by space, gear inventoried and protected, every room returned to duty.
A decommissioned server room where a decade of pulled hardware was stacked to the ceiling, racks, drives, PDUs, cable by the mile. Every drive wiped and logged, working gear resold, the rest to certified recycling. The room came back with airflow, labels, and an aisle you can walk.
A one-person electronics shop where "useful spares" filled every surface and both back rooms over fifteen years. A phased triage recovered the valuable parts into a labeled library, cleared two rooms, and got the bench usable again, without tossing the stock that paid the bills.
