Hiring someone to blast years of grime off your driveway or siding sounds simple — until you get wildly different quotes and have no idea what's fair. Knowing how much does pressure washing cost before you pick up the phone puts you in a much stronger position. Here's exactly what drives the price and what you should expect to pay.
Average Pressure Washing Costs at a Glance
Most homeowners pay between $100 and $500 for a standard residential pressure washing job, though larger or more complex projects can push well past $1,000. Professionals typically charge in one of two ways:
- Per square foot: $0.10 – $0.50 per sq ft is common
- Flat rate per surface: driveway, deck, house exterior each priced separately
- Hourly rate: $50 – $150 per hour depending on your region and the contractor
A single-car driveway (around 400 sq ft) typically runs $80 – $200. A two-story home exterior might range from $300 – $800.
What You're Actually Paying For
Price isn't arbitrary. Contractors factor in several real costs:
- Labor: The biggest driver. Experienced techs charge more, but they also know how to avoid stripping paint or etching concrete.
- Equipment: Commercial-grade machines (3,000–4,000 PSI) cost far more to own and maintain than rental units.
- Cleaning agents: Soft washing — a low-pressure method paired with detergents — often costs slightly more but is safer for roofs, painted wood, and stucco.
- Travel and setup time: Remote locations or difficult-to-access areas add cost.
- Water usage: Some contractors factor in water costs, especially for large jobs.
Price by Surface Type
Different surfaces require different pressure levels, nozzles, and techniques — which affects pricing.
| Surface | Typical Cost Range | |---|---| | Driveway / concrete | $80 – $250 | | Deck or patio | $100 – $350 | | House siding (vinyl/brick) | $150 – $600 | | Roof (soft wash) | $300 – $700 | | Fence (wood or vinyl) | $100 – $300 | | Sidewalk / walkways | $50 – $150 |
Roofs almost always require soft washing rather than high-pressure blasting, which keeps shingles intact but uses more chemical treatment — hence the higher price tag.
Factors That Push the Price Up or Down
Size matters most. A 500 sq ft patio costs far less than a 2,000 sq ft wraparound deck. Always get quotes based on actual measurements, not estimates.
Condition of the surface. Heavy mold, oil stains, or years of buildup take longer to remove and may require multiple passes or specialty degreasers. Expect a surcharge of 10–25% for heavily soiled surfaces.
Accessibility. A single-story ranch is straightforward. A three-story home or a deck built over a slope requires longer hoses, scaffolding, or extra safety precautions — all of which cost more.
Region. Labor rates in the Northeast and West Coast run 20–40% higher than rural Midwest or Southern markets. Always benchmark quotes against local averages.
Season. Spring and early summer are peak season for pressure washing. Booking in fall or late winter can sometimes get you a 10–15% discount.
Soft Wash vs. Pressure Wash: Does It Affect Cost?
Yes, and it's worth understanding the difference before you hire anyone.
- Pressure washing uses high-pressure water (2,000–4,000 PSI) to physically blast away dirt. Best for concrete, brick, and stone.
- Soft washing uses lower pressure (under 500 PSI) combined with biodegradable cleaning solutions. Safer for roofs, wood siding, and painted surfaces.
Soft washing often costs 10–20% more due to the chemical solutions involved, but it's the right method for delicate surfaces. A contractor who offers only high-pressure washing for everything is a red flag.
How to Avoid Overpaying
Before hiring, run through this quick checklist:
- Get at least three written quotes that specify the surfaces, square footage, and method being used
- Ask whether the price includes cleaning agents and spot treatment for stains
- Verify they carry general liability insurance (minimum $1M coverage)
- Check reviews specifically mentioning the surface type you need cleaned
- Confirm they won't use high pressure on surfaces that require soft washing
Comparing quotes is easier than it used to be — Mercoly lets you find and compare trusted pressure washing providers in your area all in one place, so you're not hunting across five different apps.
Quick Summary
For most residential jobs, budget $150 – $500 and adjust based on surface type, square footage, and your local market. The lowest quote isn't always the best deal — inexperienced operators can etch concrete, damage siding, or void deck warranties.
Get your quotes, ask the right questions, and book a provider you can actually trust.
