💧 Pressure Washing Cost Calculator
Exterior house washing removes mold, mildew, algae, and dirt from siding — vinyl, wood, brick, and stucco. Most pros use soft wash (low-pressure + surfactant) to avoid damage. Typical 2,000 sq ft house runs $300–$600. Two-story homes cost 20–40% more. Optional add-ons: gutter brightening, window cleaning, and driveway included pricing.
How Much Does Pressure Washing Cost?
Pressure washing costs depend heavily on the surface type, square footage, condition, and whether you need specialty services like soft wash, hot water, or post-wash sealing. As a rule of thumb: $150–$400 for a driveway, $200–$600 for house washing, and $100–$300 for a deck. Commercial jobs start at $150–$300 minimums and scale by square footage.
The industry spans two overlapping categories: pressure washing (high-PSI mechanical cleaning) and soft washing (low-PSI chemical cleaning). Knowing which method your surface needs is the difference between clean results and a damaged surface — stucco and vinyl siding almost always need soft wash; concrete driveways and brick can handle high pressure.
Cost by Surface Type
| Surface | Price Range | Typical Job | Method |
|---|---|---|---|
| Vinyl siding (house) | $0.15–$0.35/sq ft | $300–$550 (2,000 sq ft) | Soft wash |
| Brick / stucco house | $0.20–$0.50/sq ft | $350–$700 (2,000 sq ft) | Soft wash / low PSI |
| Concrete driveway | $0.10–$0.20/sq ft | $100–$180 (500 sq ft) | Surface cleaner |
| Pavers / stamped concrete | $0.15–$0.25/sq ft | $150–$250 (500 sq ft) | Low-medium PSI |
| Wood deck | $0.25–$0.75/sq ft | $100–$250 (300 sq ft) | Low PSI + brightener |
| Composite deck | $0.20–$0.50/sq ft | $80–$200 (300 sq ft) | Soft wash |
| Wood fence | $1.50–$3.00/linear ft | $225–$450 (150 LF) | Low PSI |
| Vinyl fence | $1.00–$2.50/linear ft | $150–$375 (150 LF) | Soft wash |
| Commercial parking lot | $0.05–$0.15/sq ft | $500–$1,500 (10,000 sq ft) | Surface cleaner |
Budget vs. Standard vs. Premium
| Tier | Who Does This | Equipment | Price vs. Standard | Best For |
|---|---|---|---|---|
| Budget | Solo operator, Craigslist find | Consumer pressure washer (1,600–2,000 PSI) | 30–40% less | Concrete, fence rinse — low risk surfaces |

| Premium | PWNA certified, manufacturer warranty | Hot water unit, reclaim system, truck-mount | 30–50% more | Commercial, restoration, stucco/EIFS, wood prep |
What Factors Drive Pressure Washing Cost?
1. Surface Type and Material
Vinyl siding is easy — low PSI, soft wash chemical, done in a few hours. Stucco is risky — high pressure blows out texture and causes costly repairs. Wood decking requires a precise touch: too much pressure raises grain, too little leaves mildew behind. Surface type determines method, chemical choice, and time — all cost inputs.
2. Square Footage and Stories
Most pressure washing is priced per square foot with a minimum charge. A second-story addition typically adds 20–30% because it requires extension wands, ladders, or lifts. Third-story work may require scaffolding, adding $300–$800 to the job. For house washing, use exterior wall square footage (perimeter × height), not floor plan square footage.
3. Surface Condition
Light maintenance cleaning (annual service) is the cheapest — surfaces respond quickly to standard surfactants and rinse clean. Heavy algae, oxidation, or oil staining requires dwell time, multiple passes, specialty chemicals, and sometimes hand-scrubbing. Plan for 25–50% higher cost when the surface has been neglected for 3+ years.
4. Soft Wash vs. Pressure Wash
Soft washing (50–100 PSI + sodium hypochlorite or surfactant blend) actually kills mold and algae at the root — pressure washing at high PSI just blasts the surface staining off temporarily. Soft-washed houses stay clean 2–4x longer. For vinyl siding, stucco, wood, and roof surfaces, always use soft wash. Cost is similar but the dwell time and chemical cost slightly increase the price.
5. Add-Ons: Gutter Brightening, Windows, Sealing
Gutter brightening removes the black tiger stripes (oxidized aluminum and tannins) from the face of gutters — a 10-minute add-on that costs $75–$150 and transforms curb appeal. Window cleaning bundles add $60–$150 depending on count. Post-wash driveway or deck sealing adds $0.50–$1.50/sq ft but extends the clean 2–3x and prevents re-staining.
DIY vs. Professional Pressure Washing
A quality consumer pressure washer runs $200–$400 to buy. A rental is $50–$100/day. So DIY driveway washing makes financial sense for a single property owner. But house washing is where homeowners make expensive mistakes: too much pressure strips paint, forces water behind siding (leading to rot and mold), and breaks window seals. Professional pressure washers carry liability insurance for a reason — a $500 cleaning job can turn into a $5,000 siding repair if done wrong.
DIY is reasonable for: concrete driveways, sidewalks, fences, patios, and vehicles. Always hire a pro for: house washing, stucco, painted wood siding, composite decking, and anything over a single story.
Pressure Washing Before Painting or Staining
Painting contractors require a clean surface — most specs call for pressure washing within 48–72 hours of painting. The cost of washing before exterior painting is typically rolled into the painting quote or runs $150–$350 as a standalone. For decks being stained, washing is mandatory: stain won't penetrate a surface coated with mildew and UV-damaged gray wood cells. A good wash plus brightener (oxalic acid treatment) opens the wood grain for maximum stain absorption.
Frequency: How Often Should You Pressure Wash?
Most exteriors benefit from annual or biannual pressure washing — spring (after winter dirt and road salt) and fall (after leaf tannin and summer algae growth). Driveways in wet climates may need washing every 6–12 months. Wood decks typically need washing every 1–2 years if sealed, every year if unsealed. A regular maintenance schedule prevents the heavy staining that requires more expensive deep-clean treatments.

Frequently Asked Questions
House pressure washing (soft wash for most siding types) typically costs $0.15–$0.35/sq ft for vinyl and $0.20–$0.55/sq ft for brick or stucco. A standard 2,000 sq ft home runs $300–$600 professionally. Two-story homes add 20–30% due to additional equipment and safety requirements. Low-rise commercial buildings run $0.10–$0.25/sq ft. Most pros use soft wash (low PSI + surfactant) rather than high-pressure spray to avoid water intrusion and surface damage — the chemical does the heavy cleaning, the water rinses it off.
Pressure washing uses high PSI (2,000–4,000+) water force to blast away dirt mechanically — ideal for concrete, brick, and stone. Soft washing uses low PSI (50–200) combined with cleaning chemicals (typically sodium hypochlorite + surfactant) that kill mold, algae, and mildew at the root. Soft wash results last 2–4x longer because the organism is actually killed, not just blasted off the surface. Vinyl siding, stucco, painted wood, and roofs should always use soft wash; high pressure on these surfaces causes water intrusion and surface damage. Many homeowners don't realize they hired a pressure washer when they needed a soft wash — this is the most common cause of siding damage from cleaning.
Concrete driveway pressure washing runs $0.08–$0.20/sq ft, with most residential driveways (400–600 sq ft) costing $75–$200. A surface cleaner attachment produces consistent results vs. wand-only washing. Oil stain pretreatment adds $50–$100. Post-wash concrete sealing adds $0.50–$1.00/sq ft but extends the clean 2–3x and blocks future oil penetration. For a 500 sq ft driveway, sealing costs an additional $250–$500 but protects your concrete and keeps it looking cleaner for much longer.
Deck washing costs $0.25–$0.75/sq ft for wood decks and $0.20–$0.50/sq ft for composite. A typical 300 sq ft deck runs $100–$250 for washing alone. When paired with staining or sealing ($1–$3/sq ft additional), most contractors offer bundled discounts. Always wash with the grain on wood decks — cross-grain pressure raises fibers and damages the surface. After washing, allow 2–3 days of drying time before applying stain or sealer. A deck brightener (oxalic acid wash) after pressure washing opens the wood grain for maximum stain absorption and can dramatically improve results.
Yes, always. Painting over dirty or mildewed siding is a common cause of premature paint failure — the paint bonds to the grime instead of the surface and peels within 1–3 years. Most paint manufacturer specifications require washing within 48–72 hours of painting. Pressure washing before exterior paint typically runs $150–$350 and is often included in painting contractor quotes. For decks being stained, washing is mandatory — stain won't penetrate gray, UV-damaged wood effectively. The washing step costs very little relative to the paint job and is one of the highest-ROI preparations you can do.
Annual washing is ideal for most homes — spring (post-winter road salt and grime) and fall (post-algae season) are the peak times. Homes in humid climates with heavy tree cover may need washing twice yearly. Driveways and concrete surfaces typically need washing every 1–2 years. Wood decks need washing every 1–2 years if sealed, annually if unsealed. Regular maintenance prevents the heavy staining that requires expensive remediation treatments, stronger chemicals, or even replacement. If you're maintaining a clean home exterior, the job gets faster and cheaper each time — if you wait 3–5 years between cleanings, the cost doubles due to the extra work needed.
Gutter brightening removes the black tiger stripes (called "zebra striping") that form on the outside face of aluminum gutters — caused by oxidized aluminum reacting with tannins and pollutants. Standard pressure washing won't remove these; they require a chemical treatment (alkaline cleaner or oxidation remover) applied and agitated by hand. Cost: $75–$150 as an add-on to house washing. The result dramatically improves curb appeal and is one of the best value add-ons in exterior cleaning — gutters often look new afterward and it's a small fraction of what you'd pay to replace them.
Commercial pressure washing runs $0.05–$0.20/sq ft for parking lots and flatwork, with minimums of $150–$300. A 10,000 sq ft parking lot runs $500–$1,500 depending on condition and reclaim requirements. Hot water units (required for grease and fleet washing) add 15–25% to the rate. Many cities require wastewater reclaim systems for commercial lots — budget $150–$300 extra if required. Contract pricing (quarterly or monthly) typically saves 10–15% vs. one-time service and keeps surfaces in better condition year-round.
