Patio Pressure Washing Cost (2026): Prices by Size and Material

A pressure washer strong enough to lift grease off concrete is also strong enough to blow the sand out from between your pavers. That is the whole patio problem in one sentence, and it is why the same 500 square feet can be a $200 job or a $400 job with a second visit attached.

Published rates run from about $0.10 to $0.50 per square foot. Angi puts a typical patio project between $80 and $500, averaging near $250. Homewyse starts around $0.39 to $0.49 per square foot under easy conditions.

That spread is not sloppiness on their part. A plain concrete slab with open access really is close to a square footage job. A paver patio with moss in the joints, a grill corner, furniture to move and a narrow side gate is not, and no per-square-foot figure will tell you which one you own.

If you want the rates for other surfaces side by side, the pressure washing cost per square foot guide has them.

2026 Patio Pressure Washing Cost at a Glance

Current published pricing sources show a fairly wide range for professional patio cleaning.

Angi reports approximately $0.10 to $0.50 per square foot for professional patio pressure washing. Homewyse’s January 2026 model starts at approximately $0.39 to $0.49 per square foot under basic, readily serviceable project conditions. Homewyse also lists $0.42 to $0.52 per square foot for basic concrete pressure washing, which provides another useful benchmark for concrete patios.

These figures should not simply be averaged together. Each source uses different assumptions about job size, labor, minimum charges, materials, preparation, and site conditions.

Published pricing sources use different assumptions. These ranges are comparison benchmarks, not guaranteed quotes for the same project.

The spread matters. At $0.10 per square foot, a 500-square-foot patio would imply only $50. At $0.50 per square foot, the same size would imply $250.

That does not necessarily mean one source is wrong. Smaller projects may encounter minimum service charges, while material, preparation, stains, furniture, access, and joint work can all change the amount of labor involved. Angi explicitly notes that its per-square-foot figures may not include project minimums or additional fees.

The useful question is not what the national rate is. It is what scope that rate assumes. At $0.10 per square foot a 500 foot patio implies $50, which no contractor is driving across town for. At $0.50 it implies $250. Both numbers are published, and the difference between them is everything this page is about.

Two patios of 500 square feet, two different jobs

Square footage tells you how large the patio is.

It does not tell you how difficult it is to clean.

Consider two hypothetical 500-square-foot patios.

Patio A: Simple Concrete Patio

• 500 sq. ft.
• Plain concrete
• Average dirt buildup
• Open rectangular layout
• Easy hose and equipment access
• No furniture
• No significant grease or rust staining

Using the WashNumbers baseline model:

500 × $0.40 = $200

Patio B: Complex Paver Patio

• 500 sq. ft.
• Concrete pavers
• Heavy organic buildup
• Moss and weeds around joints
• Outdoor furniture to move
• Grill-area grease staining
• Narrow backyard access
• Joint sand requiring protection and inspection

The floor area is still 500 square feet, but the actual cleaning scope is clearly larger.

That is why WashNumbers treats size, condition, access, and surface characteristics as separate variables instead of pretending square footage explains the entire job.

The joint sand problem

This is one of the most important differences between a paver patio and a solid concrete patio.

Joint sand helps fill and stabilize the spaces between pavers. Unilock advises protecting that sand during cleaning and says that if joints look low after pressure washing or heavy rinsing, clean sand should be swept back into the gaps after the patio dries.

Pressure washing can therefore create three different scenarios:

1. Joints remain intact

The patio is cleaned carefully and little or no joint material is lost.

This is closest to a normal cleaning-only job.

2. Some joint sand is displaced

The patio may still be successfully cleaned, but the joints need inspection and potentially additional sand.

3. Joint restoration is part of the project

This is a different scope from cleaning alone.

Techniseal’s restoration guidance even describes intentionally pressure washing pavers deeply enough to remove joint material before replacing it as part of a restoration process. That is not the same service as a basic maintenance wash.

For pricing purposes, homeowners should therefore ask whether a paver quote includes:

• surface cleaning only,
• replacement of displaced joint sand,
• complete re-sanding,
• polymeric sand,
• or sealing after cleaning.

Those services should not be assumed to be interchangeable.

How size and the minimum charge interact

To make size comparisons easier, WashNumbers uses a transparent planning model rather than presenting one published national average as a guaranteed market price.

For this page, the WashNumbers baseline patio model uses:

• Base rate: $0.40 per sq. ft.
• Modeled minimum charge: $100
• Average condition: 1.00×
• Normal access: 1.00×
• Planning range around the modeled result: ±20%

The $0.40 baseline is a modeling assumption selected within the current published patio pricing ranges. It is not presented as a measured national contractor average.

You can read how WashNumbers separates published pricing data from planning assumptions on our methodology page.

WashNumbers formula

Estimated price = max($100, square footage × $0.40 × condition factor × access factor)

For an average-condition patio with normal access:

WashNumbers planning model for an average-condition patio with normal access. These figures are modeling outputs, not contractor quotes or published market averages.

Planning ranges apply ±20% to the modeled result, with the $100 modeled minimum acting as the lower floor for small projects.

Why Small Patios Can Cost More per Square Foot

One useful result of modeling a minimum charge is that the effective cost per square foot increases sharply on very small jobs.

A contractor still has to travel to the property, unload equipment, connect water, prepare the area, perform the cleaning, pack up, and travel to the next job whether the patio is 100 square feet or 500 square feet.

Homewyse’s own patio model includes a balance of two hours of minimum labor, which supports the broader point that small exterior-cleaning jobs cannot always be priced by square footage alone.

Under the WashNumbers example above:

• 100 sq. ft. at the modeled $100 minimum = $1.00/sq. ft. effective
• 200 sq. ft. = $0.50/sq. ft.
• 500 sq. ft. = $0.40/sq. ft.
• 1,000 sq. ft. = $0.40/sq. ft.

This is why multiplying a small patio by the lowest online per-square-foot rate can produce an unrealistically low estimate.

Patio Pressure Washing Cost by Material

Material affects more than appearance. It can change cleaning technique, pressure selection, chemical use, time spent on stains, and the risk of disturbing joints or damaging the surface.

Angi currently lists approximately $130–$220 for concrete patios and $210–$250 for brick or paver patios in its material comparison. It also notes that brick and paver surfaces may require gentler cleaning than concrete.

These published project ranges do not prove that every paver patio costs more than every concrete patio. They do show why material needs to be part of the estimate.

Concrete Patio Pressure Washing Cost

Concrete patios are often among the simpler patio surfaces to estimate because they usually consist of a continuous slab without hundreds of sand-filled joints.

That does not mean every concrete patio is easy.

Oil or grease around grills, heavy algae, rust marks, paint, deep staining, poor drainage, or a deteriorated surface can all increase preparation and cleaning time. Angi specifically notes that preparation such as sweeping and applying degreaser can add labor to a patio-cleaning project.

For homeowners comparing similar concrete surfaces, our driveway pressure washing cost guide provides another useful reference for larger exterior concrete areas.

Paver Patio Pressure Washing Cost

Paver patios deserve separate treatment because the contractor is not cleaning only the visible face of each paver.

There is also a joint system between the units.

Unilock warns that incorrect pressure or nozzle settings can damage pavers or blow joint sand out of the joints. Its maintenance guidance recommends keeping the wand moving, using a fan spray, and directing the stream carefully to reduce sand loss.

If joint sand is removed, the cleaning job may create a second task: replacing it once the surface is dry.

That is an important reason a 500-square-foot paver patio should not automatically be treated as equivalent to 500 square feet of plain concrete.

Brick Patio Pressure Washing Cost

Brick patios also combine surface cleaning with joint considerations.

Angi currently places brick or paver patios above concrete in its published material examples and notes that these materials may require gentler techniques.

Older brick, deteriorating mortar, algae in joints, uneven sections, and heavy organic buildup can make the job more detailed than cleaning a flat concrete slab.

Natural Stone Patio Cleaning

Natural stone is too broad a category for one universal pressure setting or cleaning method.

Flagstone, limestone, slate, and other natural materials can react differently to chemicals, pressure, stains, weathering, and existing sealers.

For that reason, WashNumbers does not assign one invented material multiplier to every natural-stone patio. The appropriate cleaning process should be based on the actual stone and condition of the installation.

Dirty and awkward: the two multipliers

WashNumbers models surface condition separately from square footage.

For planning purposes, our current patio model uses:

• Light buildup: 0.90×
• Average buildup: 1.00×
• Heavy buildup: 1.15×

Condition Example for a 500 Sq. Ft. Patio

Heavy buildup may involve more dwell time, repeated passes, spot treatment, or additional preparation.

A small patio covered in algae or grease can therefore require more work than a larger patio with only loose dirt.

The patio may be behind the house even when the contractor’s vehicle is parked in front.

That distance matters.

WashNumbers currently models access as:

• Easy access: 0.95×
• Normal access: 1.00×
• Difficult access: 1.10×

Factors that can make access more difficult include:

• narrow side gates,
• stairs,
• long hose runs,
• equipment that must be carried manually,
• limited parking,
• enclosed courtyards,
• landscaping that restricts movement,
• or a water connection far from the work area.

Furniture, grease, drainage and edges

Furniture and Preparation

Outdoor furniture, planters, grills, rugs, toys, and decorative items may need to be moved before cleaning.

Homeowners can sometimes reduce preparation time by clearing the patio before the contractor arrives.

Grease and Oil Stains

A patio used for grilling may contain grease that does not respond like ordinary dirt.

Angi specifically identifies degreasing as an example of preparation that can add labor time.

Moss, Algae, and Organic Growth

Shaded or damp patios can accumulate organic growth, especially around joints and low-drainage areas.

Cleaning may involve treatment in addition to mechanical rinsing.

Drainage

The contractor needs somewhere for dirty water to move.

Low spots, poor drainage, nearby doors, pools, landscaping, or enclosed courtyards can complicate runoff management.

Edges, Steps, and Borders

A 500-square-foot rectangle is generally simpler than 500 square feet divided into multiple levels, steps, curved borders, retaining-wall edges, and narrow sections.

The measured floor area may be identical, but the amount of detail work is not.

The important question is therefore not simply, “What is the national price per square foot?” It is:

What scope of work does that rate assume?

A clean, open concrete slab may be close to a straightforward square-footage job. A paver patio with sand loss, algae between joints, furniture, grease stains, landscaping around every edge, and difficult hose access is not.

What counts as an add-on, and what does not

A basic patio washing quote should not automatically be assumed to include every restoration service.

Potential add-ons can include:

• degreasing or stain treatment,
• furniture moving,
• joint-sand replacement,
• complete paver re-sanding,
• polymeric sand installation,
• sealing,
• cleaning steps or adjoining walkways,
• or treatment of especially difficult stains.

Angi currently estimates patio sealing as an additional $180–$370, depending on material and patio size.

That figure is useful as a published reference, but sealing should be treated as a separate service rather than quietly included in a pressure-washing estimate.

How to measure your patio

For a rectangular patio:

Length × width = square footage

Example:

20 ft × 25 ft = 500 sq. ft.

For an L-shaped or irregular patio, divide it into smaller rectangles, calculate each section, and add them together.

Example:

• Main section: 20 × 20 = 400 sq. ft.
• Side section: 10 × 10 = 100 sq. ft.
• Total = 500 sq. ft.

Do not automatically include the square footage of a driveway, walkway, pool deck, wall, or steps unless those surfaces are actually being cleaned.

If you want to estimate an entire exterior-cleaning project instead of only the patio, use the WashNumbers Pressure Washing Cost Calculator.

Four patios, worked out in full

The following examples use the WashNumbers planning model, not contractor quotes.

Example 1: Small Concrete Patio

200 sq. ft. × $0.40 = $80

Because this falls below the modeled $100 minimum:

Planning estimate: $100

This shows why very small patios can have a high effective per-square-foot rate.

Example 2: 500 Sq. Ft. Average Patio

500 × $0.40 × 1.00 condition × 1.00 access = $200

Typical modeled estimate: $200
Planning range: $160–$240

Example 3: 500 Sq. Ft. Patio With Heavy Buildup and Difficult Access

500 × $0.40 × 1.15 × 1.10 = $253.00

Typical modeled estimate: about $253
Planning range: about $202–$304

This example demonstrates why two patios with the same square footage can produce meaningfully different estimates.

Example 4: 750 Sq. Ft. Light-Buildup Patio With Easy Access

750 × $0.40 × 0.90 × 0.95 = $256.50

Typical modeled estimate: about $257
Planning range: about $205–$308

These examples are intended for budgeting and comparison, not as substitutes for local contractor quotes.
