Concrete or asphalt surfaces. Oil stains need chemical treatment. Recommended: 3,000-4,000 PSI
High pressure OK on concrete. Watch for joint sand displacement.

How to Use This Pressure Washing Calculator
Step 1: Pick the surface you're cleaning. Different surfaces need different pressure and chemicals — this affects cost.
Step 2: Measure the area in square feet. For a driveway, length × width. For house siding, perimeter × wall height.
Step 3: Be honest about dirt level. Heavy moss or oil stains add 20-40% to the base price because of pre-treatment chemicals.
What Factors Affect Pressure Washing Cost?
Surface type
Concrete ($0.20-$0.40/sq ft) is cheapest — handles high pressure. Wood decks ($0.50-$1.00) cost more because low-pressure cleaning takes longer. Roofs ($0.50-$1.00) require soft wash and specialized chemicals.
Accessibility
Second-story siding, steep roofs, and fenced yards add 20-40% because of setup time and safety equipment. Most pros charge extra for ladder work.
Dirt level & stains
Light annual cleaning is cheapest. Heavy moss, oil stains, or rust require pre-treatment chemicals ($0.05-$0.15/sq ft extra) and dwell time (15-30 minutes before washing).
Chemicals & water reclamation
Bleach-based cleaners are standard for organic growth. Oil degreasers add cost. Some jurisdictions require water reclamation (especially California) — adds $50-$150 per job.
Bundling multiple surfaces
Most pros offer package deals: house + driveway + walkway for $400-$700 (vs $600-$900 separately). Always ask about bundling if you have multiple surfaces.
Pressure Washing Cost Breakdown
| Component | % of Total | What it covers |
|---|---|---|
| Labor (crew + travel) | 50-60% | Setup, application, cleanup. Most companies charge 1-2 hour minimum. |
| Equipment & fuel | 15-20% | Commercial washer depreciation, gas, maintenance, nozzles |
| Chemicals & cleaners | 15-25% | Bleach solution, detergents, degreasers, brighteners |
| Overhead & profit | 10-15% | Insurance (critical for roof work), marketing, contractor margin |

Pressure Washing Prices by Surface
| Surface | $/sq ft | Method |
|---|---|---|
| Concrete driveway / walkway | $0.2-$0.4 | 3,000-4,000 PSI |
| House siding (vinyl/stucco/brick) | $0.15-$0.35 | 500-1,500 PSI (soft wash) |
| Wood deck / patio | $0.5-$1 | 1,200-1,500 PSI |
| Wood or vinyl fence | $0.3-$0.6 | 1,200-2,000 PSI |
| Roof (asphalt shingle) | $0.5-$1 | 100-500 PSI (soft wash only) |
Roof cleaning MUST use soft wash (100-500 PSI) with bleach solution. High-pressure washing strips asphalt shingle granules and voids the manufacturer warranty. If a contractor offers to "pressure wash" your roof at high PSI, refuse — they will cause $5,000-$15,000 in premature roof failure.

The standard pricing approach: most contractors price by square foot for large jobs (1,000+ sq ft) and by flat rate for small jobs (minimum $100-$150). Bundling multiple surfaces saves the homeowner 20-30% because travel and setup costs are shared.
My pricing sheet: driveway $0.30/sq ft, house siding $0.25/sq ft, deck $0.75/sq ft, roof soft wash $0.75/sq ft. I add a $50 chemical surcharge for heavy moss or oil stain treatment. Most quotes take 10 minutes on-site with a measuring wheel.
The recurring revenue play: offer annual maintenance contracts at 70% of one-time price. Homeowners love the "set it and forget it" aspect, and you get predictable off-season income. About 40% of my customer base is on annual contracts.
Insurance is non-negotiable: pressure washing causes property damage more often than you'd think (broken windows, damaged siding, water intrusion). Carry minimum $1M general liability. Roof cleaning specifically requires a separate endorsement — many policies exclude roof work.
Frequently Asked Questions
How much does pressure washing cost per square foot?
Pressure washing costs $0.15-$1.00 per square foot depending on surface type. Concrete driveways are cheapest ($0.20-$0.40/sq ft). House siding runs $0.15-$0.35/sq ft (soft wash). Wood decks and roofs cost $0.50-$1.00/sq ft due to specialized low-pressure requirements. Most companies have a $100-$150 minimum service fee, so small jobs cost more per square foot.
How much does it cost to pressure wash a driveway?
A standard 2-car driveway (1,000 sq ft) costs $200-$400 to pressure wash. This includes pre-treatment for oil stains, high-pressure cleaning (3,000-4,000 PSI), and rinsing. Heavily stained driveways with 5+ years of neglect cost 20-40% more. Most contractors bundle driveway + walkway + porch for $300-$600 total.
How much does it cost to pressure wash a house?
Pressure washing a house exterior costs $200-$800 depending on size and siding material. A 1,500 sq ft single-story vinyl home runs $250-$450. A 2,500 sq ft two-story stucco home runs $500-$800. Siding cleaning must use low-pressure 'soft wash' (500-1,500 PSI) with chemical detergents — high pressure forces water behind siding and causes mold. Brick and stucco cost more than vinyl.
What's the difference between pressure washing and soft washing?
Pressure washing uses high-pressure water (1,500-4,000 PSI) to physically blast away dirt. Good for concrete, brick, and metal. Soft washing uses low-pressure water (100-500 PSI) combined with chemical solutions (bleach-based) to kill algae/mold and dissolve grime. Required for roofs, siding, and wood — high pressure on these surfaces causes permanent damage and voids warranties. Most pros offer both, choosing based on surface.
How often should I pressure wash my house?
Most homes benefit from pressure washing every 1-2 years. Homes in humid climates (Southeast US, Gulf Coast) need annual cleaning to control algae and mold. Dry climates (Southwest) can go 2-3 years between washes. Driveways and walkways need cleaning every 1-2 years or when oil stains appear. Roofs with visible black streaks (gloeocapsa magma algae) should be soft-washed immediately — the algae eats away at shingle granules.
Can I pressure wash my own house?
DIY pressure washing is possible for concrete surfaces (driveways, walkways) if you own or rent a gas-powered washer ($200-$500 rental for a weekend). But house siding and roofs should always be done by pros: (1) consumer-grade electric washers (1,500-2,000 PSI) are too weak for effective cleaning; (2) improper technique damages siding, etches wood, strips roof granules; (3) chemical handling requires training (bleach solutions can kill landscaping if not neutralized). For anything beyond concrete, hire a pro.
Is pressure washing a profitable business?
Pressure washing has some of the highest margins in home services — typically 60-80% gross margin. Overhead is low (equipment $2,000-$5,000 for pro setup, no storefront needed). Average job ticket is $300-$600, and an experienced tech can do 3-5 jobs per day. The challenge is seasonality (cold-climate businesses close November-March) and customer acquisition. Most successful pressure washing businesses use Google Business Profile + nextdoor + door hangers for leads.
