💩 Why it's ugly
The job lives in ceiling cavities, mechanical rooms, old ductwork, and documentation folders with names like final_final_revised. It is not glamorous. It is barely visible on purpose.
💰 Why it prints money
Hospitals, schools, hotels, and commercial buildings need periodic life-safety inspections. Compliance deadlines, deficiency reports, and repeat testing schedules make demand recurring and less price-sensitive than ordinary maintenance.
