Pressure Wash the Grime Off

Our Pressure Washing Services can remove Moss, Algae, & Grime on Walkways & Siding

Pressure Washing Moss and Algae in Portland, OR

You want to refresh your home by removing the moss, algae, and grime that’s on your walkways, steps, siding, decks, fences, retaining walls, driveways, and gutter exteriors. We want to make life easier for you.

Sure, you could go to a big box, buy a cheap pressure washer, come home, spend all day cleaning your driveway, or whatever else it is you feel you can safely clean (without, say, damaging your siding or decking by using the wrong pressure or the wrong tip), and then store and maintain that pressure washer indefinitely until it breaks down. A better idea is to just call us and let us make it easy for you. Our pressure washing experts will give your home the clean and attractive look it deserves. We take pride in our quality work, and we can’t wait to help you make your home shine.

We use professional-grade 3500 psi, 4 gallons per minute equipment, as well as professional circular scrubbers, to clean your dirty, slippery, algae or moss-covered surfaces, quickly and efficiently. We bring our own hoses and know what pre-cleaners and tips to use to get you the best result in the most efficient manner. We can also use environmentally friendly cleaners to help your process along. We use just the right pressure to remove dirt and debris from the surface and protect your home from potential damage. Every project is unique, which is why we tailor our services to meet your needs.

We offer a 100% Satisfaction Guarantee

At Action Northwest we believe in doing a great job, every time. That’s why we stand behind our 100% Satisfaction Guarantee. That’s right, if you’re not happy, we’ll make it right free of charge. No worries. No hassles.

How to Get it Clean?

Pressure Washing: Concrete or Brick Flat Work and Retaining Walls, Exterior Gutters

For safety and a fresh look, we will pressure wash concrete or brick walkways, steps, patios, driveways, and retaining walls, as well as exterior gutters. Portland’s wet, mild weather often encourages algae, grime, and moss to accumulate where you walk. Putting up a sign that says “Slippery When Wet” won’t really help. But our pressure washing will!

Green Clean and Gentle Wash: Wood or Vinyl Decks and Fences

Are your wood fences or decks turning green, black, or gray from algae and mold? Are your vinyl fences turning green or black? We clean fences and decks, too. Our proprietary Gentle Wash process is a soft wash that cleans the grime off vinyl decks and fences, and for cedar wood gets a deep clean in a non-damaging way. Our proprietary Green Clean process thoroughly cleans wood fences and decks and is environmentally friendly. Both of these processes leave wood ready to re-stain.

House Washing

House Washing Is The Gentle Alternative To Pressure Washing Your Siding

House washing is a great alternative to Pressure Washing  Your Exterior Siding in Portland, Oregon

Take a look at the outside of your home: does your siding have green, black, or gray areas of algae, mildew, or mold on it, especially on the north side? If so, it’s time to get it cleaned off. We use a proprietary soft wash process, where we apply a cleaner and then a low-pressure rinse to clean the siding, removing dirt, algae, mold, and mildew. We can do the entire house or just the side that needs cleaning. Mold and mildew may stain some siding, and the stains won’t come out, but we can remove what is causing the stains and prevent them from getting worse. We can wash wood siding, cedar siding, Hardiplank, and vinyl siding. If you are getting ready to paint, this process works great. We also have solutions for fireplace exteriors of stone or brick chimneys.

Does the black stuff damaged siding? From a structural standpoint, the damage is usually minimal, but it will deteriorate organic (wood) siding and stain the synthetic siding. Keeping the black stuff cleaned off will make your home look well-maintained, increasing its eventual resale value, plus it just feels nice to drive up to a clean-looking home. Since it’s unsightly your HOA may even require you to do so. Keeping your home looking well-maintained may help keep your home insurance rates from going up.


Taking care of your home the right way every time, with a 100% Satisfaction Guarantee. Since 2004 we’ve been specializing in happy clients. Experience, training, safety compliance, and accountability, assure your work is done to the highest professional standards, every time.
