How Much Does Pressure Washing Cost? Complete Pricing Guide
Pressure washing is one of the highest-impact home maintenance services you can invest in. A few hours of professional work can make your driveway, siding, deck, and walkways look brand new — boosting curb appeal, preventing long-term damage, and adding real value to your property.
But how much should you actually pay? Pressure washing pricing varies significantly based on the surface, the size of the job, the cleaning method, and your location in Oregon. This guide breaks down costs for every common residential and commercial pressure washing project.

Pricing by Surface Type
Driveway Pressure Washing: $100 - $300
| Driveway Size | Cost |
|---|---|
| Single car (~200 sq ft) | $75 - $150 |
| Double car (~400 sq ft) | $100 - $200 |
| Triple car (~600 sq ft) | $150 - $300 |
| Extra-long driveway | $200 - $400 |
Driveways are the most commonly pressure washed surface. Concrete driveways in Oregon develop moss, algae, and oil stains due to our wet climate. Most contractors charge $0.15 to $0.40 per square foot for driveway washing.
Add-ons:
- Sealing after washing: $0.15 - $0.30/sq ft additional
- Oil stain pre-treatment: $25 - $50 per stain
- Moss treatment application: $50 - $100
House Siding: $200 - $600
| Home Size | Siding Cost |
|---|---|
| Small (under 1,500 sq ft) | $200 - $350 |
| Medium (1,500 - 2,500 sq ft) | $300 - $500 |
| Large (2,500+ sq ft) | $450 - $700 |
| Multi-story surcharge | +$50 - $150 |
Most siding requires soft washing (low pressure with cleaning solution) rather than high-pressure washing, which can damage vinyl and wood siding. Oregon homes are particularly prone to algae and mildew growth on north-facing walls.
Deck and Patio: $100 - $350
| Surface | Cost |
|---|---|
| Wood deck (300 sq ft) | $100 - $250 |
| Concrete patio (300 sq ft) | $75 - $200 |
| Composite deck (300 sq ft) | $100 - $250 |
| Stone patio (300 sq ft) | $125 - $300 |
| Staining after wash (wood) | $2 - $4/sq ft additional |
Oregon decks take a beating from rain, moss, and UV exposure. Pressure washing followed by staining or sealing extends deck life by years.
Fence: $150 - $400
| Fence Type | Per Linear Foot | 150 ft Fence |
|---|---|---|
| Wood | $1.00 - $2.00 | $150 - $300 |
| Vinyl | $0.75 - $1.50 | $112 - $225 |
| Metal / Wrought Iron | $1.00 - $2.50 | $150 - $375 |
Roof Cleaning: $300 - $700
Roof cleaning in Oregon almost always uses soft washing (low pressure, chemical treatment) rather than high-pressure washing, which damages shingles.
| Roof Size | Cost |
|---|---|
| Small (under 1,500 sq ft) | $250 - $400 |
| Medium (1,500 - 2,500 sq ft) | $350 - $550 |
| Large (2,500+ sq ft) | $500 - $700 |
| Moss treatment application | $100 - $200 additional |
Oregon moss growth is a major roof concern. Untreated moss retains moisture, lifts shingles, and accelerates roof deterioration.
Pricing Models: How Contractors Charge
| Model | Rate | Best For |
|---|---|---|
| Per square foot | $0.10 - $0.50/sq ft | Large, measurable surfaces |
| Per project (flat rate) | $100 - $1,000+ | Defined scope of work |
| Hourly | $50 - $100/hour | Complex or variable jobs |
| Package deal | 10-20% discount | Multiple surfaces, whole-house |
Whole-house packages offer the best value. Most Oregon pressure washing companies offer a bundled rate for driveway + siding + walkways + deck that saves 15% to 25% over individual pricing.
Factors That Affect Price
Surface material. Delicate surfaces (wood, vinyl, painted surfaces) require low pressure and specialized solutions, which can increase time and cost.
Level of contamination. A driveway that is been neglected for 5 years costs more than annual maintenance washing. Heavy moss, algae, or staining requires pre-treatment and additional passes.
Accessibility. Multi-story homes, steep driveways, and properties with limited water access may incur surcharges.
Water source. Most contractors bring their own water supply or connect to your outdoor spigot. Properties without accessible water may incur a water delivery fee.
Oregon climate factor. Our wet climate means more organic growth (moss, algae, mildew) than most of the country. This makes pressure washing more labor-intensive in Oregon but also more necessary and effective.
When to Pressure Wash in Oregon
| Season | Ideal For | Notes |
|---|---|---|
| Spring (Mar-May) | Whole house, driveways, decks | Best time — remove winter buildup before summer |
| Summer (Jun-Aug) | All surfaces | Peak season, book early |
| Fall (Sep-Oct) | Gutters, walkways, driveways | Prep before rainy season |
| Winter (Nov-Feb) | Not recommended | Rain, cold, slow drying |
Recommended frequency:
- Driveways and walkways: Annually
- House siding: Every 1-2 years
- Decks: Annually (with stain/seal every 2-3 years)
- Roof: Every 2-3 years (moss treatment annually)

DIY vs. Professional Pressure Washing
| Factor | DIY | Professional |
|---|---|---|
| Equipment cost | $150-400 (purchase) or $50-100/day (rental) | Included |
| Risk of damage | High (wrong pressure ruins surfaces) | Low (trained operators) |
| Time investment | 4-8 hours for a house | 2-4 hours |
| Results quality | Variable | Consistent |
| Safety | Risk with ladders, electrical, slips | Insured and trained |
DIY pressure washing is tempting but risky. Using too much pressure on siding, decking, or roofing causes irreversible damage. Professional operators know the correct PSI, nozzle distance, and chemical ratios for each surface.
Commercial Pressure Washing Costs
| Property Type | Cost | Frequency |
|---|---|---|
| Storefront (sidewalk + entrance) | $100 - $300 | Monthly to quarterly |
| Parking lot (per 1,000 sq ft) | $100 - $200 | Quarterly |
| Building exterior | $500 - $2,000 | Annually |
| Dumpster pad | $75 - $150 | Monthly |
| Drive-through lane | $150 - $300 | Monthly |
