Pressure Washing Cost Calculator

Leave any surface blank to exclude it · Enter two or more surfaces to see the bundle discount · For the house, enter your home's total square footage — pros commonly price house washing by home size

Roofs, painted surfaces, stucco, and wood need soft washing, not high pressure · Most companies enforce a service minimum, so a small job can cost more per square foot than a large one · Bundling several surfaces in one visit typically saves money

Estimates based on 2026 US average pricing from Angi, HomeGuide, Invoice Fly, and UseCalcPro. Actual costs vary by region, surface material, and how dirty the surfaces are. Always get 3 quotes from licensed, insured pressure washing companies.

Understanding the Calculator Inputs

Pressure washing is priced surface by surface, because each material needs a different method, different chemicals, and carries a different level of risk. A concrete driveway can take a lot of pressure and gets cleaned quickly. A roof can't take high pressure at all and is slower, more careful work. This calculator prices each surface at its own rate, then combines them the way a real multi-surface quote works.

Surface Type — The Biggest Price Driver

Concrete flatwork (driveways, sidewalks, patios) is the cheapest per square foot. House siding sits in the middle. Wood decks and fences cost more per square foot because they need a gentler approach. Roofs cost the most per square foot because they require soft washing with a cleaning solution and carry real fall risk.

Dirt Level, Access, and Region

Heavy buildup — oil stains, black algae streaks, rust, or years of mold — needs stronger cleaners, longer dwell times, and sometimes more than one pass, which adds roughly 25–50% to the price. Second-story walls and steep roofs need ladder or lift work. High-cost metro areas run meaningfully above the national average.

3 Real-World Pressure Washing Examples

Example 1 — Driveway Only (600 sq ft)

A homeowner wants just the concrete driveway cleaned, light staining, national average pricing.

Real-world note: This is why small jobs look expensive per square foot. Most companies won't send a crew for less than a set minimum, so a 600 sq ft driveway effectively costs at least $150 no matter how the math works out. If you have other surfaces that need cleaning, adding them to the same visit spreads that minimum across more work.

Example 2 — House Plus Driveway Bundle (Two-Story, 2,000 sq ft Home)

A two-story 2,000 sq ft home gets a full exterior wash plus the 600 sq ft driveway in one appointment, light dirt, national average pricing.

Real-world note: Booking several surfaces in one visit typically saves 15–25% compared with booking each separately, since the crew sets up once. When you're collecting quotes, ask each company for a bundled price rather than pricing each surface on its own.

Example 3 — Roof Soft Wash (2,000 sq ft Roof, Two-Story Home)

A roof with moss and algae streaking on a two-story home needs a soft wash, routine condition, national average pricing.

Real-world note: Roof cleaning is priced higher per square foot because it must be done with a soft wash method rather than high pressure, and because of the safety risk. Heavy algae buildup can add another 25–50%. If your roof is already near the end of its life, see our Roof Replacement Cost Calculator before paying to clean it.

Pressure Washing vs. Power Washing vs. Soft Washing

These three terms get used interchangeably, but they're different methods with different costs, and using the wrong one on the wrong surface is how damage happens.

Additional Cost Factors

Hidden Costs Most Estimates Miss

1. The Service Minimum

Most companies enforce a minimum of roughly $150–$200 regardless of how small the area is. A single small patio or walkway will almost always cost more than the per-square-foot math suggests.

2. Heavy Soil Surcharge

A quote based on a quick look at a lightly dirty surface can grow once the crew finds oil stains, rust, or thick algae. Ask whether the quote assumes routine dirt and what the surcharge would be if the surface turns out worse.

3. Add-On Services

Gutter cleaning, gutter brightening, and window washing are frequently offered as add-ons at the time of booking. Gutter work is often priced per linear foot, so it's worth deciding in advance whether you want it rather than agreeing on the spot.

4. Height and Access

Second-story walls, elevated decks, and steep roof pitches take more setup time and involve real safety risk, and that shows up as a surcharge. Confirm whether your quote already assumes the height of your home.

5. Sealing, Staining, or Painting Afterward

Cleaning is usually the first step, not the last. Concrete often gets sealed afterward, and wood decks and fences are typically stained. Those are separate projects with their own costs — see our Driveway Sealcoating Cost Calculator and Fence Staining Cost Calculator for that next step.

Common Estimation Mistakes

Using High Pressure on Everything

As covered above, high pressure is right for concrete and wrong for roofs, painted surfaces, stucco, and most wood. Damage from a bad wash can cost more to repair than the wash itself, so verify the method before work starts.

Choosing the Lowest Quote Without Checking Insurance

An inexperienced operator can damage siding, window seals, or a roof. Confirm the company carries liability insurance before hiring, especially for house and roof work.

Comparing Quotes Built on Different Measurements

One company may price house washing by your home's square footage while another prices by measured wall area. Ask what each quote is based on, and compare total prices rather than per-square-foot rates.

Booking Each Surface Separately

Because the crew sets up once, bundling several surfaces in one visit typically saves 15–25%. Booking a driveway one month and the house another means paying the service minimum twice.

Treating a Roof Like a Driveway

Attempting to pressure wash a roof, or hiring someone who does, can strip protective granules from shingles and shorten the roof's life. Roofs should only ever be soft washed.

How the Calculator Works

Total = Σ(Area × Surface Rate × Condition × Access) × Bundle Discount × Regional Multiplier, raised to the service minimum if lower

Each surface you enter is multiplied by its own per-square-foot rate range. Heavy staining multiplies the result by 1.25–1.5. Two-story and steep-roof access multiply the house and roof lines by 1.25 and 1.5 respectively; those access multipliers are planning estimates, since pricing sources describe height as a surcharge without a fixed percentage. When two or more surfaces are included, a bundle discount reduces the subtotal by 25% at the low end and 15% at the high end. The regional multiplier then scales the total (0.9 for lower-cost regions, 1.3 for high-cost metros). Finally, if the result falls below a typical $150–$200 service minimum, it's raised to that minimum.

Factors That Affect Your Actual Cost

Surface Material

Vinyl, brick, stucco, fiber cement, and painted wood siding all tolerate different pressure levels and cleaners. If you're considering replacing your siding instead of cleaning it, see our Siding Cost Calculator.

Shade, Humidity, and Tree Cover

Shaded, humid properties grow algae and mildew faster, which means dirtier surfaces and more frequent cleaning. Heavy buildup pushes a job into the higher-cost category.

Regional Labor Rates

High-cost metro areas run 20–40% above the national average, while much of the South and Midwest runs below it. See the regional patterns on our Patio Cost Calculator for similar variance.

Planning Around Other Projects

Pressure washing is often step one before painting, staining, or sealing. If you're preparing for a fresh coat of paint, see our Exterior House Painting Cost Calculator, and for measuring your surfaces accurately, use our Square Footage Calculator.
