EXPOSED
This catch-all covers specialty cleaning work — chimney sweeping, duct and vent cleaning, pressure washing, high-rise window and exterior work, post-construction and biohazard cleanup — performed by hand in cramped, dirty, variable spaces that no current robot navigates. Language AI touches almost none of it; the exposure here is scheduling, quoting, and dispatch getting absorbed by software, plus commercial floor-scrubbing robots nibbling at the flat-open-space end. The score is middling not because the labor is automatable but because there is no license, no signature, and little client relationship protecting the wage.
Tasks largely resist digitisation. Sweeping a flue by feel, snaking a brush through offset ducts, rigging a swing stage for a 30-story glass face, or scraping cured grout and mortar off post-construction floors are all irregular-geometry hand tasks with no two jobs alike — an 18 rather than 20 only because route scheduling, quoting square footage, and the flat-open-warehouse floor scrubbing at the margins are already going to software and ride-on autoscrubbers.
Hands-on in uncontrolled environments. The work is ladders, roofs, crawlspaces, confined-space entries, pressure washers at 3,000+ psi, and respirators against creosote, mold, and bloodborne pathogens — uncontrolled environments in every sense, docked one point only because a slice of the category is interior mid-rise window work on solid footing.
No licence, no signature requirement. No state licence gates the trade; a CSIA chimney sweep certification or an IICRC or OSHA 10 card helps you win bids and satisfy an insurer, but nothing stops an uncertified crew from underbidding you tomorrow — the 4 is those voluntary credentials, not legal protection.
Some relationship component. Repeat chimney and dryer-vent customers call the sweep they trust inside their house annually and homeowners do ask for the same pressure-washing crew, but commercial and GC work is awarded on the low bid to whoever the property manager's system dispatches, which caps this at 8 instead of the low teens.
Executes defined procedures on defined inputs. Calls like whether a flue liner is cracked enough to condemn or which chemical to use on a stained façade are real but bounded by manufacturer specs, NFPA 211, and a supervisor's sign-off on the scope — you flag the problem, the customer or the GC decides, which is a 6 rather than discretionary authority.
