The length of a power washing service depends on several factors, including the size of the property, the type of surface being cleaned, the level of dirt or organic growth, and whether soft washing or high-pressure cleaning is required. While every job is unique, professionals follow predictable time ranges based on years of industry experience.
Contractors found through the PowerWashing.com Directory follow standardized processes that ensure efficiency without sacrificing cleaning quality or safety.
⭐ 1. Residential Cleaning Time Estimates
Below are average timeframes for common residential services:
House Washing (Soft Wash)
1–3 hours, depending on:
Smaller homes with light buildup may be completed in under an hour, while larger two-story homes with heavy organic growth require more dwell time and careful rinsing.
Driveway or Concrete Cleaning
45 minutes – 2 hours
Variables include:
High-efficiency surface cleaners significantly cut the job duration and improve consistency.
Roof Soft Washing
1.5–3 hours
Roof cleaning takes longer due to:
Because roofs must be soft washed (never pressure washed), technicians take extra care to protect shingles, gutters, and landscaping.
Deck or Fence Washing
1–2.5 hours
Factors include:
Wood cleaning requires slower, controlled movements, which adds to the time.
⭐ 2. Commercial Cleaning Time Estimates
Commercial jobs vary widely, but here are typical ranges:
Storefront Cleaning
30 minutes – 1.5 hours
Quick, high-visibility work focusing on windows, signage, sidewalks, and entrances.
Restaurant & Drive-Thru Cleaning
1–3 hours
Grease, oil, and heavy foot traffic require more prep, hotter water, and degreasers.
Parking Lot / Parking Garage
2–8+ hours
Large flatwork areas require multiple surface cleaners, hot water systems, and sometimes nighttime scheduling.
Multi-Story Building Washing
Half-day to multi-day projects
Lift equipment, rope access, and safety protocols extend the timeline.
⭐ 3. Industrial Cleaning Time Estimates
Industrial environments typically involve:
Industrial Degreasing
2–6 hours, depending on severity.
Warehouse Cleaning
2 hours – full day, based on square footage.
Fleet Washing
5–20 minutes per vehicle, scaled up depending on fleet size.
⭐ 4. Factors That Influence Cleaning Time
Professionals assess these variables before giving an estimate:
Surface size
More square footage = more time.
Level of buildup
Mildew, moss, oxidation, and grease require longer dwell times.
Access & obstacles
Fencing, landscaping, furniture, and elevation impact workflow.
Equipment used
A pro using 8 GPM hot water rigs works far faster than a 2–3 GPM homeowner machine.
Chemistry
Proper detergents reduce pressure requirements and speed up the job.
Rinse time
Rinsing is often 50% of the service, especially for soft washing.
⭐ 5. Final Takeaway
Most residential jobs take 1–3 hours, while commercial and industrial work ranges from short-duration storefront cleanings to multi-day building or garage projects.
