Pressure washing quotes can vary wildly—sometimes by hundreds of dollars for the same job. Getting three or four estimates before hiring is standard practice, but knowing what to compare actually matters.
What Gets Included in a Pressure Washing Quote
A legitimate quote should break down more than just a flat fee. Look for line items like:
- Service type: soft washing (lower PSI, chemical-based, safer for delicate surfaces), standard pressure washing (2500–4000 PSI), or hot water washing
- Square footage or linear footage: for house siding, driveways, or deck cleaning
- Surface type: concrete, wood, vinyl, brick, or shingles—each requires different approaches and affects pricing
- Travel or mobilization fees: some companies charge $50–$150 if you're far from their service area
- Additional treatments: sealing after cleaning, moss prevention, or rust removal typically add $0.10–$0.30 per square foot
If a quote just says "$300 to clean your house," that's a red flag. You won't know what's actually included or why it differs from competitor quotes.
Typical Price Ranges to Expect
Residential pressure washing pricing varies by region and scope, but here are realistic baselines:
- House siding: $0.08–$0.20 per square foot (typically $400–$800 for a 2,000 sq ft home)
- Driveway: $0.10–$0.25 per square foot ($300–$600 for 2,000 sq ft)
- Deck cleaning: $0.15–$0.35 per square foot ($600–$1,200 for a 2,000 sq ft deck)
- Roof cleaning (soft wash): $0.15–$0.40 per square foot (higher due to safety equipment and chemical costs)
- One-time gutter cleaning: $150–$400 depending on home size
If a quote is 50% cheaper than others, ask why. It might indicate inexperience, outdated equipment, or they're underestimating the job scope.
Key Questions to Ask Each Company
Before comparing numbers, get clarity:
- What PSI and equipment will you use? Soft washing (under 1500 PSI) is necessary for wood, vinyl, and asphalt shingles. Higher pressure on these surfaces causes damage.
- Are chemicals included, or billed separately? Some companies quote labor only, then surprise you with chemical surcharges.
- What happens if I'm not satisfied? Will they re-do problem areas at no cost within 30 days?
- Do you carry liability insurance? Non-negotiable. A slip-and-fall on your property could cost you without coverage on their end.
- How soon can you start, and how long will the job take? This affects scheduling and gives you a reality check on whether they're rushing jobs.
How to Spot Unreliable Quotes
- Vague scope: "We'll clean your exterior for $500" without specifying what's included
- No written estimate: verbal quotes disappear if there's a dispute
- Payment upfront in full: reputable companies take 30–50% deposits, with the balance on completion
- No insurance mentioned: they're either uninsured or hiding it
- Pressure washing everything at 4000+ PSI: shows they don't understand surface-specific techniques
Making Your Comparison
Organize quotes in a simple table:
| Company | House Siding | Driveway | Deck | Soft Wash? | Insurance | Travel Fee | Timeline | |---------|--------------|----------|------|-----------|-----------|-----------|----------| | Company A | $450 | $350 | $600 | Yes | Yes | No | 2 weeks | | Company B | $320 | $280 | $500 | No | Yes | $75 | 1 week | | Company C | $400 | $400 | $750 | Yes | No | No | 3 weeks |
Side-by-side comparison makes trade-offs obvious. The cheapest option might skimp on soft washing for delicate surfaces; the most expensive might include unnecessary add-ons.
Don't Ignore Reviews and Credentials
Price alone doesn't tell the story. Cross-reference quotes with:
- Google reviews and Yelp ratings (look for consistency across 20+ reviews)
- Before/after photos specific to your surface type
- State licensing if required in your area
- How they handle warranty claims (mentioned in reviews)
Services like Mercoly let you compare multiple trusted pressure washing providers and their quotes in one place, streamlining this research.
Frequently Asked Questions
Q: Is it worth paying more for soft washing instead of regular pressure washing? Yes, if you have wood siding, vinyl, or asphalt shingles—soft washing protects these surfaces from damage and extends their lifespan by years.
Q: Can I negotiate a pressure washing quote? Sometimes, especially if you're bundling multiple services (siding + driveway + deck) or booking during their slower season (fall/winter in most regions).
Q: How often should I get pressure washing done? House siding every 2–3 years, driveways annually (or every other year), and roofs only as needed when moss/algae appears—don't let anyone convince you it's a yearly necessity.
