Clark County’s wet winters leave concrete slick with moss, algae, and the black film that builds up in shaded spots. Pressure washing strips it off driveways, sidewalks, patios, and walkways so they look clean and stop being slippery. We handle homes and commercial properties across Vancouver, Camas, Washougal, Battle Ground, Ridgefield, and the rest of Clark County.
We match the pressure to the surface. Concrete gets full pressure, while wood decks and fences get a lower setting so the grain isn’t torn up. Siding and roofs never get high pressure. They’re soft washed instead, so look at our house washing and soft wash roof cleaning pages for those. Every job starts with a free estimate.


Concrete here spends most of the year damp. Moss grows into the joints, algae turns patios and walkways green, and shaded slabs get slick enough to be a real fall risk by November. The before-and-after on this page is a typical Vancouver backyard patio. Nothing was wrong with the concrete underneath, it had just disappeared under a few seasons of growth.
Pressure washing takes the growth off at the surface and pulls it out of the joints and cracks, where it holds water and slowly breaks the concrete down. Unlike painting or sealing, it doesn’t need a dry stretch. We clean concrete through the fall and winter, which is exactly when moss-covered steps and walkways get dangerous. A yearly cleaning keeps them safe to walk on and stops the growth from coming back thicker every spring.
Most of our pressure washing is concrete: driveways, sidewalks, patios, walkways, and front steps. We also clean pavers and the concrete around pools, garages, and commercial entrances. The patio in the photo had algae built up under a gazebo, where the shade kept it wet year-round. It came back to clean concrete in one visit.
We use a surface cleaner for the flat work. It’s a spinning head that cleans evenly, so you don’t end up with the stripes and wand marks a pressure washer leaves when it’s run by hand. Pavers get the same treatment, with a lighter touch on the joints so the sand between them stays put. If we’re already out for your roof or gutters, adding the driveway and walkways to the same visit is the easiest way to get it done.

Awesome roof cleaning company! My husband and I were having a party and wanted to try to get our deck awning cleaned in time for the party. Jessa and Zach worked together to squeeze us in and Zach did a fantastic job! Both were friendly and professional every step of the way, and we will definitely utilize their services again!Posted on Google![]()

Clark County Roof Cleaning is excellent on their cleaning service. They were on schedule from the beginning of the scheduling of estimate to service confirmation, and project executions. The coordination and communication from Jessa of the office were so precise without any confusion. I had soft washing for moss removal and power wash for my driveway. Ian of the company did an excellent job for me. I have been very pleased and satisfied with their services from the beginning to the Job completion, and would recommend Clark County Cleaning to anyone who needs the service. I rate Clark County Roof Cleaning service 5 out of 5.Posted on Google![]()
