How much does pressure washing cost? There is no single price, because nobody is selling the same job twice. A shaded two-story house with a long driveway and a mildewed fence is a very different afternoon from a one-story slab home with a short, sunny drive. What you can know in advance is the published range for each surface and the handful of things that push a job toward the top or bottom of it.
This guide pulls those published ranges into one table, explains how pressure washing companies charge, and shows what to tell a company so its number reflects your actual property.
Read this before the numbers. Every figure below is a third-party published range from the publisher named beside it. None of them is a price from Houston Power Washing Pro, which is a free phone line and does not quote, or from any company the line connects you with. The company you talk to sets its own price. The figures were checked in October 2026 as shown on each publisher's page, and publishers update them, so follow the links in Sources for the current version.
Published pressure washing prices by surface
Angi publishes a Houston page, so its local figures are listed where they exist. HomeAdvisor and Forbes Home figures are national.
| Surface or job | Published figure | Publisher and scope |
|---|---|---|
| Most residential pressure washing projects | $213 to $448 for most projects; about $0.10 to $0.50 per sq ft; minimum charge of about $100 | HomeAdvisor, national (page labelled 2025 data) |
| Whole house exterior, Houston | Average $266; range $175 to $380; $0.09 to $0.45 per sq ft | Angi, Houston page |
| Whole house exterior, national | Average about $400; range $200 to $1,250; about $1 per linear ft (one story), $1.50 (two story), $2.25 (three story) | Forbes Home, national |
| Siding only, Houston | $125 to $1,200 | Angi, Houston page |
| Driveway | $75 to $225 (Houston); $0.30 to $0.55 per sq ft (national) | Angi, Houston page; HomeAdvisor, national |
| Patios, walks and pool decks | $75 to $175 for a patio (Houston); $0.20 to $0.40 per sq ft for outdoor concrete (national) | Angi, Houston page; HomeAdvisor, national |
| Wood deck | $75 to $225 (Houston); $0.30 to $0.35 per sq ft (national) | Angi, Houston page; HomeAdvisor, national |
| Fence | $125 to $250 (Houston) | Angi, Houston page |
| Roof | $0.50 to $1 per sq ft to pressure or power wash a roof | HomeAdvisor, national (see the roof cleaning cost guide for more) |
Two things stand out. First, the Houston page sits below the national figures: Angi's Houston average for a house wash ($266) is lower than its national average ($312). Second, the publishers do not agree with each other, partly because they define a "house" differently and partly because they collect prices in different ways. Treat the table as a sense of scale, not a target.
How do pressure washing companies charge?
When you compare prices, it helps to know which yardstick a company used. You will usually see one of these.
Per square foot
The usual method for flat areas: driveways, walks, patios and pool decks. The company measures length times width and applies its rate. Bigger slabs often get a lower rate per foot because setup time is spread over more area.
Per linear foot
Common for siding, fences and gutters, where height matters more than area. Forbes Home's published figures rise from one story to three because higher walls take longer and need more care.
By the hour
Used for jobs that are hard to measure, like a cluttered back patio, an outdoor kitchen or a mix of small areas. Ask for an estimate of hours up front so the final bill does not surprise you.
Flat price per surface, plus a minimum
Many companies simply look at the job and name a price for each surface. Most also have a minimum charge, which HomeAdvisor puts at about $100 nationally, to cover travel and setup on small jobs.
Pressure washing cost per square foot, worked through
If a company prices your driveway by area, you can sanity check the number yourself. Measure the length and width in feet and multiply. A slab 20 feet wide and 30 feet long is 600 square feet. Applying HomeAdvisor's published national driveway range of $0.30 to $0.55 per square foot to that slab gives roughly $180 to $330. That is arithmetic on a national figure, not a quote, and it leaves out a minimum charge, stain treatment and anything else on the property.
The useful part is the measurement. A company that hears "about 600 square feet of driveway plus a 40 foot front walk" can give you a far tighter number than one that hears "a normal driveway."
What moves the price
The publishers above name the same short list of factors. Here is what each one means on a Houston property.
- Size Square footage of flat areas, and for the house, how many stories and how many linear feet of wall. A second story usually means ladders or extension equipment and more time.
- Surface Concrete takes pressure well and goes quickly. Siding, stucco, painted wood and roofing need soft washing, which uses low pressure and a cleaning solution, and takes longer to do properly.
- How dirty it is Light dust rinses off. Thick green mildew on a shaded wall, black growth under a tree, oil drips and orange rust rings each need their own pre-treatment.
- Access Narrow side gates, steep lots, no outside water tap, or a pool and plants hugging the wall all add setup and care.
- Plants and runoff Wetting down beds before and after, covering delicate plants and keeping wash water out of the street drain take extra time on every job.
- Property type Commercial work can involve after-hours scheduling, water recovery and, under Texas rules, sales tax on nonresidential cleaning. Ask the company to explain its invoice.
Why Houston homes tend to need more treatment
Going by the current National Weather Service climate normals for Bush Intercontinental, a typical year in Houston brings close to 52 inches of rain. Combine that with the damp mornings the region is known for and walls, roofs and fences in shade stay wet long enough for mildew and algae to settle in. That growth is the reason so many Houston jobs need a soft wash solution and not just water, and the solution and extra care are part of what you pay for.
It also explains why two neighbors can get different prices for houses of the same size. The one under a big oak, with the north wall facing the fence line, simply has more to remove.
Where a low price usually comes from
A quote far below the others is not automatically a bad deal, but it is worth one more question. The usual explanations are that it covers fewer surfaces than you thought, it leaves out stain treatment, or it assumes high pressure everywhere. High pressure on siding or shingles is faster and cheaper for the company, and it is also how granules get stripped off roofs and water gets forced behind siding. Ask which method will be used on each surface before comparing totals. The guide to getting a pressure washing quote walks through what a written quote should list.
Getting a real price for your property
Published ranges get you in the right neighborhood. The actual number comes from a company that knows your property. Calling (832) 662-4107 is free: an automated assistant answers at any hour, asks what needs cleaning and roughly how big it is, and puts your call through to a separately owned pressure washing business in your part of town. That business may ask for photos or come out to look, then gives you its own price.
- List every surface. House, driveway, walk, patio, fence, roof. Leaving one out is the most common reason a price changes later.
- Give rough sizes. Driveway length and width, number of stories, fence length. Your closing papers or property tax record often show the home's square footage.
- Describe the dirt. Green and slimy, black streaks, oil spots or orange rust. Each one points the company toward a different treatment.
- Mention any deadline. An HOA letter or a listing date helps the company plan.
How this line works: Houston Power Washing Pro is a free phone line, not a pressure washing company. It connects you with an independent local pressure washing company, which inspects, quotes, does the work and is paid by you directly. Houston Power Washing Pro never charges callers. It may be paid a referral fee by the companies it connects callers with. How it works.
Services these prices cover
Residential Pressure Washing
Driveways, walks, patios, pool decks and other hard surfaces around a Houston home, matched with a company that sizes the pressure to the surface.
House Washing and Soft Washing
Low-pressure soft washing for brick, fiber cement, vinyl and stucco, so green mildew and black streaks come off without forcing water behind the siding.
Driveway and Sidewalk Cleaning
Concrete driveways, front walks and curb strips cleaned with surface cleaners, plus treatment for tire marks, mildew and the dark band along the lawn edge.
Fence Cleaning
Gray, mildewed wood fences brought back without furring the boards, plus vinyl and wrought iron fences.
Pressure washing prices around Houston
The line takes calls across greater Houston. Lot size and tree cover change prices more than the city name does: wide driveways and fenced yards are common in Katy and Pearland, while heavily wooded lots in The Woodlands tend to mean more mildew on siding and roofs. Stubborn drips and rings are covered in oil and rust stain removal, and the roof cleaning cost guide covers roofs in detail.
