How Long Will It Take to Pressure Wash Your Patio?


As a pressure washer aficionado, I get asked this question a lot: “How long will it take to pressure wash my patio?” The truth is, there’s no one-size-fits-all answer. Several factors influence the cleaning time. This guide will break down those factors and provide you with a realistic estimate for your patio project.

Key Points Covered in this Article:

Patio Size and Complexity: This is the biggest factor. A small, rectangular patio will take less time than a large, multi-tiered one with planters and furniture.

Surface Material: Different materials require varying cleaning intensity. Concrete cleans faster than stone or brick, which might require more delicate techniques.

Level of Grime: Heavily stained or neglected patios will take longer than those with light dirt build-up.

Your Pressure Washer’s Power: Higher PSI (pounds per square inch) machines can clean faster, but it’s crucial to choose the right tip and pressure for your patio surface to avoid damage.

Your Technique and Experience: A seasoned pressure washer wields the tool efficiently, minimizing wasted time.

Patio Size and Complexity

The size and layout of your patio significantly impact the time required to pressure wash it. Here’s how these elements come into play:

Small, Simple Patios

A small, straightforward patio (up to 200 square feet) can usually be pressure washed in 30 minutes to an hour. These spaces typically feature minimal obstacles, allowing for a quick and efficient cleaning process. For instance, a simple rectangular patio without any furniture or intricate designs can be cleaned swiftly with a high-powered pressure washer.

Large or Complex Patios

Larger patios, especially those over 500 square feet, will naturally take more time. If your patio has multiple tiers, built-in planters, or an irregular shape, expect to spend more time navigating and cleaning these areas. On average, a large or complex patio may take anywhere from 2 to 4 hours to clean thoroughly.

Obstacles and Furniture

The presence of furniture, planters, and other decorative elements can add to the cleaning time. Each item needs to be moved or cleaned around carefully, which can significantly slow down the process. Ensuring all obstacles are cleared before starting can help reduce the total time spent pressure washing.

Surface Material

The material of your patio plays a crucial role in determining how long it will take to pressure wash. Different surfaces have different levels of porosity and texture, affecting how easily they can be cleaned.

Concrete Patios

Concrete is one of the most straightforward surfaces to clean with a pressure washer. It’s durable and can withstand high pressure, allowing you to clean it quickly and effectively. A concrete patio typically takes less time to clean, averaging about 1 to 2 hours for a standard size.

Stone and Brick Patios

Stone and brick patios, while beautiful, can be more challenging to clean. These materials are often more porous and textured, requiring a gentler approach to avoid damage. Cleaning stone or brick can take 2 to 3 hours or more, depending on the level of dirt and staining.

Wooden Decks and Patios

Wood requires a delicate touch, as high pressure can damage the surface. Cleaning a wooden patio often takes longer, as you need to use lower pressure and potentially spend more time on areas with heavy grime. Expect to spend around 2 to 3 hours on a wooden patio, especially if it’s been neglected for a while.

Level of Grime

The condition of your patio is another significant factor. The more dirt, mold, algae, or stains present, the longer it will take to clean.

Light Dirt Build-Up

If you maintain your patio regularly, it may only have a light layer of dirt and debris. In this case, pressure washing can be relatively quick, often taking about an hour for a small to medium-sized patio.

Heavy Stains and Neglect

A patio that has been neglected or subjected to heavy use will require more time. Stubborn stains, mold, and algae can be challenging to remove and may require multiple passes with the pressure washer. For heavily stained patios, expect to spend anywhere from 2 to 4 hours, depending on the size and severity of the grime.

Your Pressure Washer’s Power

The specifications of your pressure washer, particularly its PSI (pounds per square inch) and GPM (gallons per minute), play a crucial role in determining how quickly you can clean your patio.

High PSI Machines

High PSI machines (3000 PSI and above) can clean surfaces much faster than lower PSI models. However, it’s essential to use the correct nozzle and pressure settings to avoid damaging your patio. With a high-powered machine, you can expect to clean a standard-sized concrete patio in about an hour.

Low to Medium PSI Machines

Machines with lower PSI (1500 to 2500 PSI) are more suitable for delicate surfaces like wood and stone. While they might take longer to clean tougher grime, they are less likely to cause damage. Using a medium-powered machine, cleaning a medium-sized patio can take around 2 to 3 hours.

Your Technique and Experience

The way you handle the pressure washer can significantly affect the time required to clean your patio. Experienced users tend to work more efficiently, making the most of their machine’s capabilities.

Efficient Techniques

Experienced pressure washers know the importance of maintaining a consistent distance from the surface and using a systematic approach to cover the entire area evenly. These techniques help avoid missed spots and reduce the need for multiple passes.


If you’re new to pressure washing, you might spend extra time adjusting settings, figuring out the best techniques, and re-cleaning missed areas. This learning curve can add an additional hour or two to the overall time required.

Tips for Prepping Your Patio for Pressure Washing

Proper preparation can save you time and ensure a more effective cleaning process. Here are some steps to take before you start pressure washing:

Clear the Area

Remove all furniture, planters, and other obstacles from your patio. This will give you a clear working space and prevent any damage to these items.

Sweep and Pre-Rinse

Sweep away loose debris and dirt from the patio surface. A quick pre-rinse with a garden hose can also help loosen up dirt and make the pressure washing process more efficient.

Protect Plants and Surroundings

Cover any plants or delicate landscaping near your patio to protect them from the high-pressure water and any cleaning solutions you might use. Tarps or plastic sheeting work well for this purpose.

Safety Precautions to Follow While Pressure Washing

Pressure washing can be hazardous if not done correctly. Here are some safety tips to ensure a safe and successful cleaning session:

Wear Protective Gear

Always wear safety goggles, gloves, and sturdy footwear to protect yourself from flying debris and high-pressure water.

Use the Right Nozzle

Select the appropriate nozzle for your surface. A narrow nozzle can deliver higher pressure but may damage delicate surfaces, while a wider nozzle is gentler but less effective on tough grime.

Be Mindful of Electrical Hazards

Avoid spraying water directly at electrical outlets, fixtures, or appliances. Water and electricity don’t mix, and this can lead to severe injury or damage.

Test the Pressure

Before starting, test the pressure on a small, inconspicuous area of your patio to ensure it won’t cause damage.

Resources for Renting or Purchasing a Pressure Washer

If you don’t own a pressure washer, there are plenty of options for renting or purchasing one.

Renting a Pressure Washer

Many home improvement stores offer pressure washer rentals. This can be a cost-effective option if you only need the machine for a one-time project. Rental fees typically range from $40 to $100 per day, depending on the machine’s power and features.

Purchasing a Pressure Washer

If you plan to use a pressure washer regularly, investing in one might be more economical. Prices for consumer-grade pressure washers range from $150 to $500, while professional-grade models can cost $500 to $1,500 or more.

Choosing the Right Model

When selecting a pressure washer, consider the types of surfaces you’ll be cleaning and how often you’ll use it. For occasional use on small patios, a medium-powered, consumer-grade model should suffice. For larger areas or frequent use, a higher-powered, professional-grade machine might be worth the investment.


By considering these factors, you’ll have a clearer understanding of the time commitment involved in pressure washing your patio. Patio size and complexity, surface material, level of grime, your pressure washer’s power, and your technique and experience all play significant roles in determining the time required. With proper preparation and technique, you’ll be well on your way to a sparkling clean outdoor space.

Pressure washing can transform your patio, making it look new again. Whether you do it yourself or hire a professional, knowing what to expect in terms of time and effort will help you plan and execute the task effectively. Happy cleaning!
