The average cost to pressure wash a deck ranges from $100 to $250, but most homeowners pay around $150. The amount you pay depends on the deck size, condition, material, and whether or not you DIY the job.

To hire the pros for a large, wrap-around deck with major grime build-up, you could pay upward of $500 or more. However, this is money well spent to keep your deck free of unsightly mold and mildew that can lead to premature deck repairs and a shorter lifespan. A clean deck also polishes up your alfresco dining experience, so you don’t have to be afraid to invite the neighbors around.

Next Steps: Finalize Your Project With a Pro
Be prepared to discuss your home size, number of floors, and home layout with your pro.

Mention what materials you have on or around your home that you want pressure washed.

Ask your pro if they use cleaners and ensure they’re safe for use around plants and pets, if applicable.

Discuss any add-on services you want, like soft washing for your roof, concrete sealing, or gutter cleaning.

Pressure Washing a Deck Cost Factors
Your final bill for pressure washing your deck depends on various factors. Here's a breakdown of what to budget for to stop you from spraying away more money than you expect.

Size
The cost to pressure wash a deck yourself is usually the same, no matter the size, but square footage plays a big part in the bottom line when you hire a local pressure washer. Tricky-to-access wrap-around decks can make the job more of a challenge, so sometimes the shape of your deck also plays a part in the pressure washing cost.

Size (Square Feet)	Average Cost
300	$100
700	$200–$300
1,000	$300–$400
Labor
While some contractors charge an hourly rate for pressure washing a deck—typically between $50 to $100 per hour, more commonly, they charge a base fee up to a specific size and then charge per square foot from there. Alternatively, they might have set prices for certain deck size ranges.

Your contractor might quote your $100 for a deck up to 300 square feet and then add a further $0.30 to $0.40 per square foot for anything over that.

Deck Condition
Have you been spilling BBQ grease all over your deck surface or letting a build-up of tricky-to-remove mold and mildew grow over a few years? Your contractor will likely up their bill to account for the extra time, effort, and deck-specific detergents required. And, if the deck has significant weathering, loose boards, or damaged areas, the contractor might also factor in the extra care needed to avoid making these issues worse during the cleaning process, potentially recommending repairs before or after pressure washing.

Deck Material

Some decking materials, like aluminum, are more capable of handling hard pressure washing than softer wood or composite decking. In that case, you might make savings because it’s quicker and easier to pressure wash a metal deck.

Material	Average Cost per 300 Sq. Ft.	Additional Details
Metal	$100	This is a tough, non-porous surface, the professionals can blast away without worrying about lifting the top layer or damaging the integrity of the decking.
Composite	$100–$150	Composite decking isn’t as durable as metal, but it can withstand pressure washing better than porous wood. It’s also less likely to suffer from mold and mildew build-up, so it might not need such a deep clean.
Wood	$100–$200	Your contractor might suggest soft washing rather than high-power pressure washing for more delicate, porous wooden decks. They will use a lower-pressure nozzle and deck detergents to lift the dirt gently.

How Often Should You Pressure Wash Your Deck?
Most pressure washing pros recommend pressure washing your wood deck at least once a year to remove dirt, mildew, and algae buildup. Depending on how often you use your deck, you might find that twice a year suits your needs better.

Spring is a good time to pressure wash your deck because it allows you to wash away any grime or mold that might have appeared during the damp winter season. However, pressure washing the deck in the fall means you can wash away greasy spills rather than letting them soak further in over the winter.

Why You Should Hire a Power Washing Pro
Power washing might seem simple, but using the wrong pressure or nozzle can damage wood fibers, leave streaks, or push water into seams where it can cause long-term rot. A local pressure washing pro can thoroughly clean your deck without harming the structure or aesthetics.

Here’s why it’s ideal to hire a pressure washing company
Here’s why you should hire a pressure washing pro to keep your deck clean and in good shape:

A pressure washing pro knows how to select the optimal pressure settings for your specific deck material.

They use cleaners that remove dirt and mildew without damaging deck finishes.

A pro can spot areas of rot or damage that may need repair, which can maintain the safety and prolong the life of your deck.

Power washing experts possess the skill and experience to clean evenly, avoiding streaks or visible lines.

They can prepare the surface for staining or sealing if needed, and they often provide those services as well.

If you want to DIY pressure washing
While you can power wash your own deck if you have extensive experience and the equipment, hiring a pro means you’ll get the best results. If you leave the job to a pro, you can still help with some of the prep or finishing steps:

Move furniture, grills, planters, and other items off the deck before your pro arrives.

Sweep the deck before the official cleaning begins.

After the work is done, you may stain, seal, or apply protective coatings if it’s a task you’re comfortable with. Otherwise, leave it to a qualified deck staining company near you.

Tips to Reduce Cost While Pressure Washing a Deck

How Often Should You Pressure Wash A Pool Deck?

An outdoor pool is a great gathering place during the summer months for relaxing, time with friends, and enjoying the sunshine. Keeping the pool deck clean not only makes the pool more visually appealing but will keep those using the pool safe from slips and health concerns. The average homeowner doesn’t have the expertise to pressure wash a pool deck, so hiring a professional to clean the surrounding area will ensure the job gets done quickly and efficiently. Here are some insights on how often you should pressure wash a pool deck for longevity.

Why Pressure Wash Your Pool Deck?
There are many reasons you should consider regular pressure washing around your home or business, but cleaning a pool deck can keep everyone safer while enjoying the water. Dirt, grime, mildew, pool chemicals, and sand can all build up on a pool deck. Not only does this cause the space to look messy but it can lead to damage to the deck material, increase the risk of slips, and spread infections.

Pressure washing will help remove stubborn debris and staining. The high-pressure stream of water can blast away any dark stains or mildew and return the pool deck to pristine condition. When pressure washing the pool deck, you ensure that you remove anything that could lead to concerns in the future.

Factors Influencing How Often Pressure Washing Should Occur
Depending on where you live and the use of your pool, your cleaning timeline could vary. Here are some factors to consider before scheduling recurring pressure washing services.

Location And Climate
Pools that are located in humid climates should be cleaned every 3-4 months. Humid climates are at higher risk of mold and algae growth, especially on concrete or pavers around a pool.

For dryer climates with dust and sand, a bi-annual pressure wash appointment will be enough to maintain the pool deck. If you are unsure how your location impacts your pool deck, ask a local pressure washer for advice.

Material Of The Pool Deck

Different materials will hold up better in certain conditions than others. For example, concrete holds up well against humidity, snow, and hail. Wood is more prone to warping and fading in the intense sun. Depending on the material of your pool deck, you may not be able to have it pressure-washed as frequently. Wood decks must be treated before they can be pressure washed and should only have this intense cleaning every 6-12 months.

Pool Usage
A pool deck with heavy foot traffic can benefit from a pressure wash at the beginning and end of the summer season. A year-round pool should have a quarterly cleaning schedule in order to avoid build-up. When determining how often to pressure wash a pool deck, consider the pool usage as well as your climate to determine what would be best.

Visible Stains
When you notice dark spots or visible stains, your deck can be pressure washed. Unsightly stains are not fun to look at and can make the pool less enjoyable. Washing these away immediately will provide a safer and better experience for all. Especially if mildew or mold has started to form, making the surface slippery, pressure washing is worthwhile.

Surrounding Vegetation
More frequent cleanings could be needed if you have falling leaves, twigs, or other debris. Removing sand, sludge, or landscaping debris quickly will protect the health of the pool and the longevity of a pool deck.

Seasonal Cleaning
Spring cleaning is a popular term that often signals a deep cleaning of forgotten areas around a home. Pressure washing after a long winter season can help reduce the likelihood of stains or algae growth on your pool deck.

You should also consider pressure washing your pool deck before the fall weather hits. During the summer, the pool has seen lots of foot traffic, harsh sun, and lots of chemicals. Pressure washing will help prepare it for the winter season and provide a clean slate for any winterization techniques.

How To Maintain The Deck Between Pressure Washings

The process of pressure washing is a great method for keeping pool decks clean, however, other maintenance techniques can also enhance the longevity of the pool deck. Sweeping, spraying with a garden hose, scrubbing the pool interior, sealing, and cleaning spills are all ways to keep your pool deck in good condition. No matter the season, these small tasks can help maintain the pristine clean received during pressure washing.
