Rope descent work

Definition

High-rise cleaning done on suspended rope, which needs certified anchors and trained crews.

Why It Matters

It pays several times ground-level rates and fences out most competitors, which is why a book carrying it holds its price. It also carries the risk. Anchorages have to be certified, the workers have to be trained and the training documented, and one lapse ends the insurance that lets a crew onto the roof. Ask to see the anchor certifications and the training records before valuing that revenue at all.
