Why graffiti sits outside a routine inclusion
Routine work is defined by predictability. A task belongs there because it recurs at a known rate and takes a known amount of time. Graffiti does neither. A building may go months without an incident and then receive a large piece across a render wall overnight, and no realistic time allowance in a routine visit covers both of those situations. Forcing it into the routine list means either paying for capacity that is rarely used or having the response fail when it is actually needed.
The other reason is technical. Removal depends entirely on the substrate and the medium. Marker on glass is straightforward. Aerosol on unsealed render is often not removable at all without leaving a shadow, and the genuine remedy is repainting. A scope that promises graffiti removal without qualifying the surface is promising an outcome that some walls cannot physically deliver, and that promise will eventually be tested.
