Project planning note
Review the selected options, site condition, material assumptions, and tool needs before buying supplies. This calculator is meant for rough DIY planning, not a professional quote.
Surface safety note
Concrete can usually tolerate more pressure, but weak or cracked areas can still be damaged. Start with lower pressure, keep the nozzle moving, and avoid spraying into outlets, panels, lights, vents, open gaps, or door thresholds.

Basic DIY checklist
- Clear loose items, furniture, planters, and trip hazards from the work area.

- Test pressure and spray pattern in an inconspicuous area before washing the full surface.
- Work in steady overlapping passes and keep the nozzle moving to avoid streaks or damage.
- Apply cleaner according to label directions, then rinse thoroughly.
- Let the surface dry fully before placing furniture back or planning any staining, sealing, or repairs.
When to call a pro
- Too much pressure can gouge wood, etch concrete, damage composite decking, remove joint sand, or force water into gaps.
- Keep water away from outlets, electrical panels, exterior lights, open doors, vents, and wall gaps.
- Call a pro for heavy mold remediation, paint stripping, high-reach work, roofs, siding near electrical hazards, or fragile surfaces.
