Expert Tips for Safely Pressure Washing Your Patio or Deck

Pressure washing is an effective way to clean and restore the look of your patio or deck. However, it’s important to approach this task with caution to avoid damaging the surface or injuring yourself. In this how-to guide, we will provide you with expert tips on how to safely pressure wash your patio or deck.

Preparing for Pressure Washing

Before you begin pressure washing your patio or deck, it’s essential to take some preparatory steps to ensure a smooth and safe cleaning process.

Clear the Area: Remove any furniture, plants, or objects that may obstruct the cleaning process. This will not only make pressure washing easier but also prevent potential damage to your belongings.

Sweep and Rinse: Start by sweeping away loose dirt and debris from the surface of your patio or deck. Then, give it a thorough rinse with a garden hose. This step helps remove surface dirt and ensures better results when pressure washing.

Protect Surrounding Areas: Cover nearby plants, electrical outlets, light fixtures, and other sensitive areas with plastic sheets or tarps. This will prevent them from getting damaged by the high-pressure water stream.

Choosing the Right Pressure Washer

Selecting the right pressure washer is crucial for achieving optimal results without causing any harm to your patio or deck material.

Consider Water Pressure: Different surfaces require different levels of water pressure for effective cleaning. For example, concrete can withstand higher pressures compared to softer materials like wood. Make sure you choose a pressure washer with adjustable settings so that you can customize it according to your needs.

Use the Right Nozzle Tip: Pressure washers come with different nozzle tips that produce varying spray patterns (e.g., fan-shaped spray). For most patios and decks, a wide-angle tip (around 25-40 degrees) is suitable as it provides adequate coverage without risking damage to the surface.

Test the Pressure: Before you start pressure washing, conduct a small test on an inconspicuous area of your patio or deck. This will help you determine if the pressure is suitable for your surface and allow you to make any necessary adjustments before proceeding.

Pressure Washing Techniques

Now that you have prepared and selected the right equipment, let’s dive into the actual pressure washing techniques.

Maintain a Safe Distance: Keep a distance of around 12-18 inches between the nozzle and the surface you are cleaning. This distance helps prevent accidental damage caused by too much pressure or getting too close to delicate materials.

Start with Low Pressure: Begin pressure washing with low pressure, especially if you are cleaning a wooden deck. Increase the pressure gradually only if necessary. High-pressure water streams can gouge or splinter wood, so it’s best to err on the side of caution.

Work in Sections: Divide your patio or deck into manageable sections and clean one section at a time. This approach ensures thorough cleaning and allows you to maintain control over the process.

Post-Cleaning Maintenance

After pressure washing your patio or deck, there are some important post-cleaning steps to follow for proper maintenance.

Allow Proper Drying Time: Give your patio or deck ample time to dry completely before using it again or applying any sealants or finishes. Moisture trapped within the material can lead to mold growth and other issues if not addressed promptly.

Inspect for Damage: Carefully inspect your patio or deck for any signs of damage after pressure washing. Look for loose boards, cracks, or splintered wood that may need repair before further use.

Apply Protective Coating (if needed): Depending on the material of your patio or deck, consider applying a protective coating like sealant or stain after pressure washing. This will help enhance its longevity and keep it looking great for years to come.


Pressure washing your patio or deck can be a rewarding task if done safely and correctly. By following the expert tips provided in this how-to guide, you can achieve outstanding results without causing any harm to the surface or yourself. Remember to prepare adequately, choose the right equipment, employ proper techniques, and perform post-cleaning maintenance for a pristine outdoor space that you can enjoy for years.
