What affects the price
- Size & surface area — the biggest driver; most jobs are priced from a per-square-foot rate.
- Condition — heavy algae, mildew, oil, or salt film needs more solution and dwell time.
- Access & height — second stories, steep roofs, and tight landscaping add labor.
- Method — soft washing (siding, roofs) uses cleaning solution and costs a bit more per foot than a plain concrete blast.
