Maintaining the pristine look of your deck is essential for both aesthetics and longevity. One effective method to achieve this is through power washing. This process can remove dirt, grime, mold, and algae, ensuring your deck remains attractive and safe. In this article, we’ll delve into the costs associated with power washing a deck, factors affecting these costs, comparisons between power washing and pressure washing, professional versus DIY approaches, and additional services like staining and sealing.
Average Cost of Power Washing a Deck
The average cost to power wash a deck is around $150. However, this cost can vary significantly, typically ranging between $90 and $770. This wide range is influenced by several factors, which we’ll discuss in detail.
Factors Affecting Cost
Deck Size
The size of your deck is one of the primary determinants of the power washing cost. Larger decks require more time, effort, and resources to clean thoroughly. Most professionals charge by the square foot, with the average cost being about $2 per square foot.
Material
The material of your deck also plays a crucial role in determining the cost. Different materials require different approaches:
- Wood: Wood decks are common and often require more gentle cleaning methods to avoid damage. This can slightly increase the cost.
- Aluminum: Aluminum decks are more durable and can withstand a more vigorous cleaning, potentially reducing the cost.
- Additional Repairs or Projects
Sometimes, decks require minor repairs or additional projects before or after power washing. This could include:
- Repairing damaged boards: Replacing or repairing damaged boards can add to the overall cost.
- Sanding: In some cases, sanding might be necessary after power washing to smooth out rough spots or prepare the deck for staining.
- Staining and Sealing: After power washing, many homeowners opt to stain and seal their decks to protect them from future damage. This is an additional cost but can be well worth it for the longevity and appearance of the deck.
Comparison with Pressure Washing
It’s essential to understand the difference between power washing and pressure washing, as these terms are often used interchangeably but involve different techniques.
Power Washing
Power washing uses heated water to clean surfaces. The combination of high pressure and hot water is effective in removing tough stains, mold, and mildew. It’s particularly useful for:
- Grease and oil stains: The heat can break down these substances more effectively than cold water.
- Killing bacteria and mold: The heat can kill bacteria and mold spores, preventing regrowth.
However, the heat can also cause damage to certain materials, particularly wood, if not used correctly.
Pressure Washing
Pressure washing, on the other hand, uses cold water at high pressure to clean surfaces. It’s suitable for:
Surface dirt and grime: Effective at removing surface-level dirt without the need for heat.
Delicate materials: Safer for use on materials that might be damaged by the heat of power washing.
While pressure washing is generally safer for most materials, it may not be as effective on tough stains or mold as power washing.

When to Use Each Method
Power Washing: Ideal for tough stains, grease, and areas with significant mold or mildew growth.
Pressure Washing: Suitable for regular maintenance and cleaning of surfaces that could be damaged by heat.
Risks Associated with Both Methods
Both power washing and pressure washing come with risks, particularly if not done correctly:
Damage to surfaces: High pressure can damage wood, paint, and other materials.
Injury risk: The high pressure can cause serious injuries if not handled properly.
Professional vs. DIY
Given the potential risks and the need for proper technique, it’s often recommended to leave power washing and pressure washing to professionals. Here’s why:
Professional Services
Expertise and experience: Professionals know the right techniques and pressures to use for different materials.
Proper equipment: Professionals have access to commercial-grade equipment that is more effective and safer.
Time-saving: Hiring a professional can save you significant time and effort.
DIY Approach
For homeowners who want to tackle the project themselves, here are some tips:
Choose the right equipment: Rent or purchase a power washer or pressure washer suitable for your deck material.
Use the correct pressure settings: Start with a lower pressure and gradually increase it to avoid damage.
Test a small area first: Test on an inconspicuous area to ensure the pressure and technique are appropriate.
Wear protective gear: Safety goggles, gloves, and sturdy footwear can prevent injuries.
Follow manufacturer instructions: Always read and follow the instructions provided with the equipment.
Cost Per Square Foot
As mentioned, most decks cost about $2 per square foot to power wash. This means that a 300-square-foot deck would typically cost around $600. However, this price can fluctuate based on the factors previously discussed.
Additional Services
In addition to power washing, homeowners often consider other services to enhance and protect their decks:
Staining
Staining a deck after power washing can help protect the wood and enhance its appearance. The cost of staining varies depending on the type of stain used and the size of the deck. On average, staining can cost between $300 and $1,300.
Sealing
Sealing is another crucial step to protect your deck from moisture and weather damage. The cost of sealing a deck is similar to staining, ranging from $300 to $1,300, depending on the deck size and sealant used.
Combined Packages
Many professional services offer combined packages that include power washing, staining, and sealing at a discounted rate. This can be a cost-effective way to ensure your deck is thoroughly cleaned and protected.
Conclusion
Power washing is an effective way to maintain your deck, but it comes with various costs and considerations. The average cost to power wash a deck is around $150, with prices ranging from $90 to $770 depending on factors like deck size, material, and additional repairs. Understanding the differences between power washing and pressure washing can help you choose the right method for your needs.
While it’s often best to leave this task to professionals, homeowners who opt for a DIY approach should take proper precautions and follow best practices to avoid damage and injury. Additionally, considering staining and sealing after power washing can further protect and enhance your deck, adding to its longevity and beauty.
Maintaining your deck through regular cleaning and protective measures ensures it remains a valuable and attractive part of your home for years to come.
