Pressure Washing

Property maintenance services that extend the life of your building

Here in the Pacific Northwest, the rainy weather causes unsightly moss, mildew, and algae growth, which can not only cause damage to siding and concrete, but can also become a slip hazard. Because of these concerns, it is important to have your property pressure washed at least once a year, or more frequently to address problem areas.

Seasonally pressure washing the buildup of dirt and grime on exterior surfaces not only improves your curb appeal; you can add years of life to your building siding, stairs, walkways, common areas, parking lots, trash enclosures, and more with our professional pressure washing services.

What We Pressure Wash

The pros at HOA Service ensure your property is pressure washed utilizing commercial pressure washing equipment and following an efficient process to safely and effectively remove the buildup of organic materials, foliage, and debris.

Different areas and materials need different techniques and consideration. Some common areas that benefit from pressure washing services include:

Building Siding & Exteriors

Your exterior building siding material determines the recommended frequency and type of washing needed. Some wood and vinyl siding require soft washing, while some benefit from pressure washing.

Garage Cleaning

Whether your property has a single parking facility or per-unit garages, we can get the job done. Our pros notice problem areas and give spots, stains, and debris attention to ensure your garage is clean and sanitary.


Wooden decks are especially susceptible to the buildup of organic material due to the porous nature of the wood. Pressure washing your decks seasonally can prevent slippery conditions, mold, and dry rot.

Roofs & Gutters

Pressure washing your roofs and gutters removes organic buildup and debris, which can add years to the life of your building. Depending on your roofing and gutter material, pressure washing may be recommended by our pros.


Over the years, the elements can wear down your concrete surfaces making inroads for the buildup of organic debris. These debris can further erode your concrete surfaces and should be pressure washed to maintain the integrity of your concrete.

Parking Lots

When your property’s first impression is the parking lot, you need a professional to make sure your common area parking areas, curbs, driveways, and paths are clean and safe for vehicles and pedestrians.   


Not only does seasonal pressure washing maintain the curb appeal of your property with sparkling sidewalks, walkways, and paths, but it also can prevent the slippery conditions caused by the buildup of organic debris.

Windows, Doors, & Trim

Pressure washing windows, doors, and trim can remove the buildup of debris on metal, glass, and wood areas which can prevent mold and dry rot. We can also pressure wash screens when removed from the window.

Stairs & Railings

Stairs and railings have many small areas where organic buildup can go unnoticed and lead to slippery conditions, mold, or even dry rot. Pressure washing the grime and debris from your stairs and rails can even prevent structural damage to these areas.


Here in Portland, Oregon we know about moss removal. Pressure washing your property’s curbs sidewalks, and other hard surfaces where moss grows, safely and non-chemically, can prevent slippery conditions and trip hazards.

Trash Enclosures

Trash enclosures can become unsanitary, unsightly, and hazardous if left unwashed for too long. Depending on the traffic at your property, we will recommend a frequency for routine pressure washing.


When graffiti occurs on surfaces that cannot be painted or exposed to harsh cleaners, pressure washing can be highly effective in removing the graffiti without damaging the surface material. 

How We Pressure Wash

For Pressure Washing service, we gather the information for the request such as specific areas and material types. Sometimes one of our supervisors will come to your property and measure the areas in your request. Once the materials our crew will be pressure washing have been examined, our experts will recommend either hard or soft pressure washing techniques to ensure the washing gently cleans without damaging the surface.

On the day of the service, our crews arrive at your property, place safety cones, and systematically pressure wash the areas in the scope of work. Our technicians take photos before and after worked performed, they remove all debris from the cleanup, and leave your property sparkling.

Once your service is complete, your account executive will reach out to you with details of the work performed and close the job for billing.

Hard Pressure Washing

When cleaning your property’s patios, decks, siding, walkways, and driveways, we use our self-contained hot and cold pressure washing system that allows for multiple technicians to pressure wash at once. This not only reduces the time it takes to complete the job, but also minimizes the use of chemicals.  

Soft Pressure Washing

Some siding, trim and fencing materials don’t stand up as well to hard pressure, or there may be recommendations from the manufacturer on how to treat the material. In these cases, we use soft pressure washing techniques, which gently clean the surface and then we rinse away any residue and debris.

Our Pressure Washing Process

You can rely on the pros at HOA Services to safely maintain the integrity of your building exterior by using only the recommended techniques for your property. Depending on the surfaces we are pressure washing, we will recommend hard or soft pressure washing techniques, or we can use a process that meets the manufacture’s specifications.

Hard Pressure Washing for Flatwork, Exposed Aggregate, Retaining Walls, Decks, Railings, Fascia etc:

  1. We pressure wash with our hot water trailer mounted pressure washer, taking care to avoid and document any areas blocked by personal property.
  2. We rinse areas to prevent lingering residue from any cleaning solutions
  3. We clean up all debris, remove it from the property, and dispose of it.


Soft Pressure Washing for Building Siding and Fences:

  1. We apply the manufacturer-specified cleaning solution to the vinyl siding using a chemical spray trailer.
  2. Using our trailer mounted pressure washer with an extended wand and extended scrub brush, we rinse and scrub vinyl siding, sometimes using low pressure depending on the material type and condition.
  3. We clean up all debris, remove it from the property, and dispose of it.
  4. Sometimes siding can become loose from cleaning due to its condition. We will repair issues like that.
  5. To avoid damage to siding heavy staining may not be able to be completely removed. We get the best result possible without adding the costs of replacing damaged materials.

Customer Reviews

Anson Whiting

They are all really cool people who are nice and easy going. If I didn’t like small things along my rebuild process, they fixed any issue I had. They put my cabinets and kitchen back together very, very well. I would use again for small things I have around the house.
