How to Bid and Price Pressure Washing Jobs: Per Square Foot Rates, Formulas, and Free Calculator
The #1 mistake pressure washing contractors make is undercharging. Here's how to price every job profitably using data-driven rates, proven formulas, and real-world examples.
Why Pricing Matters More Than Any Other Skill
You can own the best equipment, run the cleanest results, and still go broke if your pricing is wrong. According to industry surveys, over 60% of pressure washing businesses that fail in their first two years cite "undercharging" as a primary factor.
The problem isn't that contractors don't work hard. It's that they guess at prices, match whatever the cheapest competitor charges, or feel guilty about asking for what the work is actually worth. This guide replaces guesswork with formulas.
The core formula: Price = (Square Footage x Rate Per Sq Ft) + Difficulty Adjustments + Minimum Job Floor. Every section below builds on this.
Know Your Costs First
Before you can set a profitable price, you need to know what each job actually costs you. Most contractors underestimate this by 30-50%, which means they're losing money on jobs they think are profitable.
Cost Breakdown Per Hour of Work:
- Equipment depreciation: $5-15/hour (pressure washer, surface cleaner, hoses, trailer)
- Chemicals & detergents: $5-20 per job (sodium hypochlorite, surfactants, downstream injectors)
- Insurance: $150-400/month (general liability + commercial auto)
- Fuel & vehicle: $10-25 per job (diesel/gas for truck and equipment)
- Labor: $20-50/hour (your time or employee wages + workers comp)
- Marketing & overhead: $5-15/hour (website, ads, software, phone)
Add these up for your operation. A typical solo operator runs $35-65 per hour in total costs. A two-person crew runs $55-90 per hour. Your prices must exceed this to make any profit. If you're just starting a pressure washing business, tracking these costs from day one will save you from months of unprofitable work.
Four Pricing Models for Pressure Washing
1. Per Square Foot Pricing (Industry Standard)
The most accurate and widely used method. Measure the area, multiply by your rate, and you have a bid. This model scales fairly — bigger jobs earn more, and you can quote consistently.
Formula: Total Price = Square Footage × Rate Per Sq Ft
Example: 2,000 sq ft driveway × $0.20/sq ft = $400
2. Flat Rate Per Surface
Set fixed prices for common jobs. Works well for standard residential work where you know the average size. Examples: "Driveways start at $150" or "Standard house wash $250-450."
3. Hourly Rate ($50-100/hr)
Charge by the hour for unpredictable jobs like graffiti removal, heavy grease cleaning, or restoration work. Most contractors target $50-100 per hour depending on their market. Higher rates ($75-100+) are typical in metro areas and for commercial work.
4. Per Project (Complex Jobs)
For large or multi-surface jobs, combine per-square-foot pricing for each surface into a single project bid. This is common for whole-property packages, commercial buildings, and HOA contracts.
Per Square Foot Rates by Surface Type (2026)
These rates reflect national averages. Adjust up 10-30% in high cost-of-living areas and down 10-20% in rural markets.
Residential Surfaces
| Surface Type | Rate / Sq Ft | Typical Job Size | Typical Price |
|---|---|---|---|
| Driveway (concrete) | $0.15-$0.25 | 600-1,200 sq ft | $150-$300 |
| Sidewalk / walkway | $0.15-$0.25 | 200-500 sq ft | $50-$125 |
| House siding (vinyl/wood) | $0.15-$0.40 | 1,500-3,000 sq ft | $250-$600 |
| Deck / patio (wood) | $0.25-$0.50 | 200-600 sq ft | $100-$300 |
| Fence (wood/vinyl) | $0.25-$0.50 | 500-1,500 sq ft | $150-$400 |
| Roof (soft wash) | $0.30-$0.75 | 1,500-3,000 sq ft | $350-$700 |
| Patio (stamped concrete) | $0.20-$0.35 | 200-600 sq ft | $75-$200 |
Commercial Surfaces
| Surface Type | Rate / Sq Ft | Notes |
|---|---|---|
| Parking lot / garage | $0.10-$0.25 | Volume pricing; reclaim water may be required |
| Storefront / building exterior | $0.15-$0.35 | Height premiums for multi-story |
| Drive-through lanes | $0.15-$0.30 | Grease treatment adds 20-30% |
| Dumpster pads | $0.30-$0.60 | Heavy degreaser required; typically $75-$150 each |
| Concrete sidewalks (commercial) | $0.10-$0.20 | Large area discounts common |
The 1% Rule for Whole-House Washes
A popular rule of thumb in the pressure washing industry: charge roughly 1% of the home's value for a full exterior house wash (siding, driveway, sidewalks, and patio).
1% Rule Examples:
$200,000 home
$2,000
$300,000 home
$3,000
$400,000 home
$4,000
$500,000 home
$5,000
This rule works best for full-service packages. Individual surface pricing (per square foot) is more accurate for single-service jobs.
The 1% rule is a quick sanity check, not a formula. If your per-square-foot calculation comes out significantly lower than 1% of the home value, you may be leaving money on the table. If it's significantly higher, double-check your measurements and rates.
How to Estimate Job Size Accurately
Your bid is only as good as your measurements. A 20% error in square footage means a 20% error in your price — and that comes straight out of your profit.
Method 1: Walk the Property
Bring a measuring wheel or laser measure to every estimate. Walk each surface, record dimensions, and calculate square footage on the spot. This is the most accurate method but takes 15-30 minutes per property and requires a site visit.
Method 2: Satellite Measurement (Fastest)
Use satellite imagery to measure surfaces remotely — no site visit needed. This is how top-earning contractors bid more jobs in less time.
Measure From Your Phone with CrewNest
CrewNest's Satellite Measurement Tool lets you measure any property from your phone or computer. Enter an address, trace surfaces on the satellite image, and get instant square footage. Then our built-in calculators automatically generate a price based on your rates.
- • Measure driveways, roofs, siding, and decks in under 2 minutes
- • No site visit required for initial estimates
- • Auto-calculate prices using your saved per-square-foot rates
- • Generate professional estimates and send directly to customers
Method 3: Estimate from Property Data
Use county tax records or Zillow to find home square footage, then apply multipliers. A 2,000 sq ft home typically has about 1,500-2,500 sq ft of exterior siding, a 500-800 sq ft driveway, and 200-400 sq ft of walkways. This is the least accurate method but works for quick phone quotes.
Step-by-Step Bidding Example
Let's walk through a real bid for a 2,500 sq ft home:
Sample Bid: 2,500 Sq Ft Ranch Home
| Service | Sq Ft | Rate | Subtotal |
|---|---|---|---|
| House wash (vinyl siding) | 2,000 sq ft | $0.25/sq ft | $500 |
| Driveway (concrete) | 800 sq ft | $0.20/sq ft | $160 |
| Front walkway | 200 sq ft | $0.20/sq ft | $40 |
| Back patio | 300 sq ft | $0.25/sq ft | $75 |
| Total Bid | $775 | ||
At $775 for roughly 2.5-3 hours of work, that's approximately $260-310/hour in gross revenue — well above the $35-65/hour cost threshold.
Adjusting for Difficulty Factors
Not all square footage is equal. A second-story house wash takes longer and carries more risk than a single-story. Heavy stains need more chemicals and dwell time. Your pricing should reflect this.
Difficulty Multipliers:
- 2nd story siding or gutters: Add 25-50% (ladder work, safety risk, slower pace)
- 3rd story or higher: Add 50-100% (lift rental may be required)
- Heavy oil, rust, or paint stains: Add 15-30% (extra chemicals and dwell time)
- Soft wash chemical treatment: Add 20-40% (SH, surfactant, and application time)
- Difficult access: Add 10-20% (tight gates, long hose runs, steep slopes)
- Water reclamation required: Add 15-25% (commercial/environmental compliance)
- After-hours or weekend work: Add 15-25%
Example: A 2,000 sq ft house wash at $0.25/sq ft = $500 base. Add 35% for two-story work = $675. Add another 20% for heavy algae requiring soft wash = $810.
Setting a Minimum Job Charge
Every job has a fixed cost regardless of size: driving to the property, setting up equipment, mixing chemicals, and packing up. This takes 30-45 minutes minimum, which means small jobs can be unprofitable if priced purely by square footage.
Recommended Minimum Charges:
Solo operator
$150-$200
Two-person crew
$200-$250
Commercial jobs
$250-$350
Soft wash jobs
$250-$400
If your per-square-foot calculation comes in below your minimum, charge the minimum. Never show up for less than it costs you to operate for an hour.
Creating Professional Estimates That Win Jobs
A professional estimate doesn't just list a price — it sells the value of your work. Customers are comparing your bid to others, and the one that looks most professional and detailed often wins, even at a higher price.
What to Include in Every Estimate:
- Itemized services: List each surface, its square footage, and the price
- Scope of work: What you'll clean, what chemicals you'll use, and what results to expect
- Before/after expectations: Set realistic expectations about stain removal
- Timeline: How long the job will take and when you can schedule it
- Payment terms: When payment is due, accepted methods, deposit requirements
- Warranty or guarantee: "Satisfaction guaranteed" or "30-day re-clean guarantee"
CrewNest's estimate and invoicing tools let you generate professional, itemized proposals directly from your phone. Measure with satellite imagery, apply your rates, and send a branded estimate in minutes — not hours.
10 Pricing Mistakes That Kill Profit Margins
- 1. Not knowing your costs: If you don't know your hourly cost, you can't know if you're profitable. Track everything.
- 2. Matching the lowest competitor: The cheapest guy is usually the one going out of business. Compete on quality and professionalism.
- 3. Guessing square footage: Eyeballing a driveway as "about 500 sq ft" when it's actually 900 sq ft costs you 80% of the job's profit. Measure everything.
- 4. Forgetting drive time: A 30-minute drive each way adds an hour of unbillable time. Factor transit into your pricing or route jobs geographically.
- 5. No minimum job charge: A $75 driveway wash that takes 30 minutes of setup/teardown and 15 minutes of driving is a money loser.
- 6. Ignoring difficulty factors: Pricing a two-story house the same as a ranch is giving away 25-50% of your labor.
- 7. Undercharging for chemicals: Soft wash jobs use $15-40 in chemicals. If you're not pricing that in, it comes out of your profit.
- 8. Not raising prices annually: Your insurance, fuel, and chemical costs go up every year. Your prices should too — 3-5% annually minimum.
- 9. Giving quotes over the phone without measuring: Phone quotes are almost always too low because customers underestimate their property size.
- 10. Not tracking job profitability: If you don't know which jobs make money and which don't, you can't improve.
How Equipment Affects Your Pricing
Better equipment means faster work, which means higher effective hourly rates. A contractor with a 4 GPM machine and a 20-inch surface cleaner can clean a driveway in half the time of someone with a 2.5 GPM residential unit.
Equipment vs. Efficiency:
- 2.5-3 GPM residential unit: ~400 sq ft/hour on concrete
- 4 GPM prosumer unit: ~700 sq ft/hour on concrete
- 5.5-8 GPM commercial unit: ~1,200+ sq ft/hour on concrete
Investing in commercial-grade equipment raises your cost basis but dramatically increases throughput — meaning you can charge competitive rates while earning more per hour.
