A professional power washing service typically takes 1 to 4 hours, depending on the size of the property, the type of surfaces being cleaned, the level of buildup, and whether the contractor is using pressure washing or soft washing techniques. Commercial properties or multi-service packages may take longer. Contractors listed in the PowerWashing.com Directory often provide accurate time estimates in advance because they use high-efficiency equipment and proven workflow systems.
Here is the complete breakdown of what affects service time.
⭐ 1. Average Service Time by Project Type
✔ House Washing (Soft Wash)
1.5–3 hours
Most residential homes fall into this range depending on square footage, height, and organic growth levels.
✔ Roof Cleaning
2–4 hours
Soft washing requires dwell time for detergents to fully break down algae and lichen.
✔ Driveway & Concrete Cleaning
45 minutes – 2 hours
Concrete varies based on oil stains, tire marks, and surface area.
✔ Patio, Pool Deck, & Walkway Cleaning
1–2 hours
Pool areas and textured surfaces require more detailed rinsing.

⭐ 2. Factors That Impact How Long a Service Takes
