How much does it cost to pressure wash a deck?

The cost to pressure wash a deck will vary based on different factors, but the average price ranges from $0.30 to $0.40 per sq. ft. So, a 500 sq. ft. deck would cost around $150-$200.

What about per square foot?

The average cost is about $0.30 to $0.40 per sq. ft. This range includes materials and labor. However, note that there are still several factors you must consider that we’ll discuss later. 

What about per hour?

Professionals bill $50 to $150 per hour; however, it’s more common to charge by sq. ft.

What about by material type?

The cost to pressure wash a deck heavily relies on the material, which is around $150 to $220. 

There are three types of deck materials with their corresponding price range per sq. ft. and per 500 sq. ft. below.

Note that wood and composite decks are typically more costly because they are made of fragile materials that require extra care.

How about a wash and stain?

Since pressure washing ranges from $0.30 to $0.40 per sq. ft. and staining typically costs $2 to $5 per sq. ft., a 1,000 sq. ft. deck will cost around $2,300 to $5,400. An estimate for staining usually includes light sanding and sealing application.

Factors that affect cost

The overall cost varies based on several aspects. Let’s learn what those factors are:


The deck material significantly affects the cost of a project because not all types can tolerate intense pressure, thus, requiring more time, effort, and additional tools to work around.


The condition of your deck plays a big part too. For example, a light layer of debris and years of grime are two very different cots.

The location also dictates the quote since many deck cleaning professionals might have to travel further to and from the job. To minimize this cost, be sure to shop locally!


Size is also one of the main contributing factors to the cost. Big decks take longer to clean – no surprise there.

Frequently asked questions

Here are some common questions about pressure washing decks.

How long does it take to pressure wash a deck?

A 500 sq. ft. deck can be cleaned in about two to three hours, depending on the condition of the job and other things like obstructions or deck details.

Should I pressure wash my deck before staining?

Definitely! We want to point out that pressure washing is a prerequisite for staining because it makes the stain adhere to the surface better. This is an absolute must.

What PSI do I need to pressure wash a deck?

There are four types of deck materials:

  • Softwood: 500 to 600 PSI
  • Hardwood: 1,300 PSI
  • Aluminum: 1,800 PSI
  • Composite: 1,500 PSI

Do I need to use soap to pressure wash a deck?

It depends on the type of buildup on the surface. If your deck has an incredible amount of oil, grease, or dirt, it is best to apply a solution.


Decks may be one of the best functional spaces to enjoy downtime. But no one wants to sit on a dirty deck. 

If this seems like a daunting task, hire a professional.
