How Much Does It Cost to Pressure Wash a House in Portland, Oregon? [2026 Data]

The average cost for pressure washing a house in Portland, Oregon, is between $265 and $601, or $433 on average. Your actual cost as a homeowner will depend on the size of your home, the condition of the exterior, and the type of materials being cleaned.

Pressure Washing Cost Factors 

Common factors that affect the cost for pressure washing a house in Portland, Oregon, include the total square footage of the home’s exterior, the number of stories, and the type of materials being cleaned. The same applies if a patio or other exterior surface is being cleaned instead of the home itself, such as pressure washing a deck or a perimeter fence.

Cost to Pressure Wash a House per Square Foot

Pressure washing costs $0.10 to $0.60 per square foot, depending on what part of your property you’re cleaning. Flat, easily accessible surfaces like driveways and patios take less effort and therefore cost less.

Note that pressure washing only a small area means that a technician will spend very little time at your home, but they still have to pay for gas, insurance, and all other overhead costs. For this reason, pressure washing costs less per square foot when you give a professional more to do. So, take some time to look around your property and think about everything that could use some spiffing up.

Cost to Pressure Wash by Project Type

You might not always intend to pressure wash your actual house. Several other areas on your property could benefit from a thorough pressure wash job, including your driveway, patio, and fence.

Here’s the average pressure washing cost for different parts of your property:

Pressure Washing Cost by Number of Stories

The cost to pressure wash your home also depends on the number of stories. If your home is two or three stories, the professional will need a ladder, scissor lift, or bucket truck to complete your project—any of which can increase your costs.

Here’s how much you’ll pay to pressure wash your home based on the number of stories:

Cost to Pressure Wash by Material

Your house’s materials can also influence the overall cost of pressure washing. This is because certain materials require special cleaning techniques, which may take longer (and cost more in labor).

Here’s how pressure washing costs are influenced by house material:

Pressure Washing vs. Power Washing Cost

Though pressure washing and power washing are often used interchangeably, they differ in method and cost. The table below outlines the key differences:

How Often Should You Pressure Wash Your House?

You should pressure wash your home once per year, and the best time to pressure wash is between March and November in most areas. These months rarely have temperatures that dip too low, so the risks of freezing water and cold temps damaging the machines is low. That said, demand is higher in the spring and summer, so you could experience longer wait times for a professional to come (and possibly higher costs).

Here’s how often you should pressure wash different areas of your home:

Pressure Washing Pro Costs

We recommend hiring an experienced professional to clean your home’s exterior because DIY mistakes can lead to personal injury and property damage. Here’s what to know about budgeting for the job.

Labor

Hiring a pressure washing pro in Portland will cost you anywhere between $250 and $565, with an average cost of $405. Keep in mind that a more experienced contractor will charge on the higher end of that range than those who are just getting started in the business. 

Taxes

Oregon is one of just a few states that do not levy a general sales tax, so the sticker price of your pressure washing job is the final price.

Tipping

While it’s not required, you might consider tipping between 5% and 20% for a job well done.

Does Pressure Washing Your House Increase Home Value?

Pressure washing your house can boost your home’s curb appeal, which will be helpful if you’re listing your home for sale in Portland. Wet weather often results in a buildup of dirt, mold, and mildew on a home’s exterior, so pressure washing can make it more attractive for potential buyers.

However, the task itself won’t increase your home’s value as much as, say, a bath remodel can. Still, pressure washing can be well worth the cost, whether it results in a faster home sale or simply increased enjoyment of your home if you’re settling down.
