Cleaning scores high on invisibility rather than disgust. The work is unremarkable, the contracts renew quietly, and the customer is a property manager whose strongest desire is to never think about it again. Barriers to entry are low, which caps the score below the waste category, but reliability compounds: Winch's forty-year run is the longest in this database. Entries score 89 to 97.
The database Category
Commercial cleaning
Two documented owners bracket this category: Brian Winch, who has cleaned Calgary parking lots by hand since 1981 and reports $600,000 to $700,000 a year, and Joshua Brown, whose Nashville pressure washing company went from $5,000 in equipment to about $2 million a year. The product in both cases is the same: a commercial property that looks looked-after, every single morning.

Why it scores boring
Common questions
How profitable is a commercial cleaning business?
The two documented owners here: Winch reports $600,000 to $700,000 a year from litter cleanup started with roughly $250 in hand tools, and Brown reports about $2 million a year from a $5,000 pressure washing start. Margins run high because the inputs are labor, contracts, and consistency.
What exterior cleaning service has the best margins?
Per Joshua Brown: roof cleaning. Soft-wash chemistry, premium pricing, and the most reliable moat in home services, homeowners who want no part of a ladder. Striping and litter contracts win on a different axis: recurrence you can set a calendar by.
