Pressure Washing House Cost: Per-Square-Foot vs. Hourly Pricing

Pressure washing has three different ways to price the same job — per square foot, hourly, or flat rate — and customers comparing quotes often don't realize they're looking at three different pricing models instead of three different prices for the same work.

How much does it cost to pressure wash a house?

The average cost to pressure wash a house is $170-$360, with most homeowners spending around $265, though the full range runs $100-$715 depending on size, surface type, and accessibility. For a 2,000 sq ft home specifically, expect $300-$600 for professional service.

Which pricing model should you actually quote?

Per-square-foot pricing runs $0.15-$0.75, which works well for larger, uniform siding jobs where square footage is easy to measure from photos or a listing. Hourly pricing runs $50-$200/hour, with $130-$160/hour most common — this fits jobs with heavy variability, like extensive mildew staining or multiple surface types (siding, deck, driveway) in one visit, where square footage alone doesn't capture the labor. Most pros settle on a flat rate derived from one of these two models rather than quoting either raw number directly to the customer.

What actually moves the price within that range?

House size is the obvious factor, but dirt level and accessibility matter just as much — a two-story home with landscaping blocking parts of the foundation, or heavy mold/algae staining that needs a stronger detergent pass, both add real time versus a straightforward single-story wash. Surface type matters too: vinyl siding, brick, and stucco all react differently to pressure and cleaning solution, which affects both time and equipment settings.

Does location change what you should charge?

Urban areas typically support pricing 15-20% higher than rural locations, driven by higher operating costs and stronger demand. If you're expanding service into a new area or comparing your rates against a competitor, check whether they're quoting from a genuinely different cost structure before matching their number.

Quote pressure washing jobs from photos

A few photos of the house — siding material, visible staining, and square footage from a listing — are usually enough to place a job in the right pricing tier before a truck rolls out. Fast Snap Pro turns those photos into a priced estimate using your own per-square-foot or hourly rates, so the number you send matches the job you'll actually do.
