| Cost factor | Why it matters |
|---|---|
| Extent of build-up | Fresh droppings are quicker to clear than thick, dried layers built up over years |
| Height and access | Roofs, ledges and gutters need access equipment |
| Type of droppings | Pigeon, gull and bat guano each carry different hazards |
| Surface | Delicate or heritage stone and brick need gentler methods |
| Disposal | Hazardous waste disposal is part of a compliant clean |
| Site | Public or occupied buildings may need out-of-hours work |
