Pressure Washing Cost Statistics (2026)

What a house wash costs

The guides do not agree, and the gap is the first thing worth knowing. According to HomeAdvisor's 2026 cost guide (homeadvisor.com), professional pressure washing costs $311 on average, with most projects landing between $213 and $448. Thumbtack's pricing data (thumbtack.com), updated January 2026, puts the national range at $241 to $418. Fixr's 2025 guide (fixr.com) sits far higher, at $500 to $900 with a $700 average, because its baseline job is a full 2,000 square foot vinyl-sided house. Housecall Pro's 2026 pricing guide (housecallpro.com), written for contractors, lists house washing at $250 to $800. Stories matter more than square feet: HomeAdvisor prices a three-story house at up to $1,800.

What this means: the "average" you quote depends entirely on which guide you open. HomeAdvisor and Thumbtack describe a typical booked job; Fixr describes a whole-house wash. For a property owner budgeting exterior maintenance across many units, the story count and the siding material are what move the price in these guides.

Rates per square foot and per hour

Most companies quote by the square foot, and the published rates span a full order of magnitude. HomeAdvisor's 2026 guide gives $0.10 to $0.50 per square foot, or about $50 to $100 per hour. Thumbtack's data runs $0.08 to $0.47 per square foot, with hourly work at $75 to $90. Fixr's 2025 range is the highest at $0.30 to $0.80 per square foot, and it notes that heated power washing costs $0.35 to $0.70. Housecall Pro's 2026 guide splits the market: residential flatwork at $0.15 to $0.75 per square foot, commercial flatwork at $0.08 to $0.40. Three of the guides also state a minimum charge, because a crew still has to drive out, set up, and mix chemicals for a 200 square foot patio.

What this means: per-square-foot quotes are only comparable when the surface is the same. A $0.30 rate on a flat driveway and a $0.30 rate on second-story siding are different jobs with different risk. When a contractor's quote is below the minimums above, it is worth asking what is not included.

Cost by surface: driveway, deck, fence, roof, patio

Flat concrete is the cheapest surface to clean and roofs are the most expensive, and every guide agrees on the order even where the numbers differ. According to HomeAdvisor's 2026 driveway guide, a driveway costs $210 on average, with most homeowners paying $100 to $350. Fixr's 2025 guide puts a 600 square foot driveway at $180 to $240. Thumbtack's June 2026 driveway data is wider, $220 to $473, with jobs as low as $128 and as high as $844. Decks run $145 to $150 on average across Fixr and HomeAdvisor. Roofs cost the most: $296 to $625 per HomeAdvisor and $450 to $700 per Fixr, and soft washing a roof runs $0.30 to $0.75 per square foot. Angi's 2026 guides (angi.com) put a fence at $90 to $500 and a patio at $80 to $500.

What this means: the roof premium is not about square footage. It is about height, setup time, and the fact that roofs cannot take pressure at all (see the PSI group below), so the work is a chemical treatment, not a blast. For a manager documenting exterior condition, "roof was cleaned" and "roof was pressure washed" are very different entries, and ARMA's guidance makes the second one a red flag on an asphalt roof.

Commercial pricing and industry size

Pressure washing is a small, crowded industry. According to IBISWorld's public industry summary (ibisworld.com), US pressure washing services revenue is $1.2 billion in 2026, after growing only 0.6% a year from 2019 to 2024. The number of businesses grew much faster: 32,193 companies in 2024, up 5.2% in one year and 5.8% a year on average since 2019. Those companies employed 41,799 people, about 1.3 workers per business, and no company holds more than 5% of the market. On the commercial side, Housecall Pro's 2026 guide prices parking lots at $0.08 to $0.25 per square foot and a large facility wash at $2,000 to $10,000 or more. Invoice Fly's 2026 pricing guide (invoicefly.com), another software vendor, puts commercial jobs at $500 to $1,200 or more.

What this means: revenue flat, business count up 5.8% a year: the same pie is being cut into more slices. That is why so many pressure washing companies now publish local-SEO blogs and why the "average commercial job" numbers in those blogs vary so much. The section on unverified claims below traces two of the most repeated ones.

PSI limits and damage risk by surface

Pressure is where the cost of a cheap wash shows up later. Fixr's 2025 house washing guide (fixr.com) suggests 3,000 to 3,500 PSI for concrete, 2,500 to 3,000 for vinyl siding, 1,000 to 1,500 for wood, and only 500 to 1,500 for brick or masonry. HomeAdvisor's deck guide caps wood and composite decks at 1,300 PSI. Angi's fence guide caps softwood at 500 PSI. Simpson Cleaning (simpsoncleaning.com), a pressure washer manufacturer, says household jobs should not need more than 3,000 PSI. Roofs are the hard line: the Asphalt Roofing Manufacturers Association (asphaltroofing.org) says never to pressure wash an asphalt shingle roof at all, because it strips granules and shortens the roof's life. The safety data points the same way. Consumer Reports (consumerreports.org), citing the Consumer Product Safety Commission, reports 6,057 emergency room visits from pressure washer injuries in 2014.

What this means: the damage a wash causes is usually invisible on the day. Etched concrete, lifted wood grain, water forced behind vinyl siding, and roof granule loss all show up months later as an inspection finding, and by then the cause is hard to prove. Before-and-after photos of every washed surface, taken the same day, are the cheapest defense.

How often surfaces need washing

The published frequency guidance is thin, and what exists comes from the same cost guides. According to Angi's 2026 deck guide, most pros recommend pressure washing a wood deck at least once a year. HomeAdvisor's 2026 guides say a driveway without heavy wear needs washing once a year, and a roof needs cleaning only every two to five years. Nobody publishes a survey of how often owners actually do it.

What this means: annual is the default for wood and concrete, multi-year for roofs. For a portfolio, the question is less "how often" and more "which units": algae and mildew on siding grow fastest on shaded north walls and in humid climates, so the same schedule does not fit every property. Exterior photos from routine inspections are the cheapest way to decide which ones are due.

Water use and wash water rules

A pressure washer uses less water than the hose it replaces, but what comes off the surface is the regulated part. According to Hotsy (hotsy.com), a pressure washer manufacturer, a garden hose faucet flows about 8 gallons per minute while a pressure washer uses 2 to 3. Under EPA's NPDES stormwater program (epa.gov), any discharge to a storm drain that is not entirely stormwater is an illicit discharge, and Phase II municipalities must run a program to find and stop them. Cities write that into local code. The City of San Diego (sandiego.gov) makes polluted wash water discharge illegal under Municipal Code 43.0304, with penalties up to $10,000 per day per incident. It lets a mobile washer send up to 2,500 gallons a day to the sanitary sewer without a permit. King County, Washington (kingcounty.gov) requires collection whenever soap or chemicals touch pavement. The City of Los Angeles (lacity.org) bans non-stormwater discharge unless a permit or exemption applies, and San Diego County (sandiegocounty.gov) tells contractors not to wash at all in wind or rain.

What this means: the $10,000-a-day number lands on the property owner as well as the contractor: San Diego's flyer says the rules apply "regardless of whether the activity is conducted by the property owner, lessee, contractor, or other persons." A contractor who cannot say where the wash water is going is a liability line item, not a cheap quote.

Claims we could not verify

Three numbers keep reappearing in pressure washing company blogs. We traced each one to where it actually comes from, and none of them holds up as stated.
