Driveway Cleaning in Portland, OR
A mossy, oil-stained driveway is one of the most common things we see in Portland — and one of the most satisfying transformations after a good pressure wash.
Driveway Cleaning in Portland's Climate
If your driveway has been sitting through a Portland winter, chances are it's showing it. Concrete stays wet for months at a time here, which is perfect for moss and algae to get established. Add in oil drips from parked cars, tire marks, leaf tannin stains, and general environmental grime, and most Portland driveways look noticeably worse than they should.
The moss issue in particular is worth taking seriously. Green moss on a concrete driveway is genuinely slippery when wet — which in Portland means it's slippery for most of the year. It's also a symptom of a surface that's holding moisture, which over time can work into cracks and accelerate deterioration.
Our driveway cleaning service uses commercial pressure washing equipment with targeted pre-treatment for oil and organic stains. The difference is usually dramatic — driveways that looked permanently discolored often come back to near-original appearance after a thorough clean. We serve homeowners throughout Portland, Tigard, Beaverton, and the surrounding metro area. Check our pricing page for starting rates.

Our Driveway Cleaning Process
Pre-Treat Stains
Oil, rust, and stubborn organic stains are pre-treated with targeted degreasers or cleaners to break them down before any pressure is applied.
Edge & Detail Work
We start at the edges, expansion joints, and any cracks before moving to the main surface. These areas collect the most debris and moss.
Surface Wash
Working in overlapping passes with commercial-grade equipment, we clean the entire driveway surface at appropriate pressure for the material (concrete vs. pavers vs. asphalt).
Rinse & Check
After the main wash, we rinse everything down and check for any remaining spots that need a second pass. We don't consider a job done until the surface is consistently clean.
Cleanup
All debris, water, and cleaning product is directed to appropriate drainage. We leave your driveway clean — and your yard the same as we found it.

Can you actually remove oil stains from a concrete driveway?
Often yes, significantly. Fresh oil stains respond better than old ones. We pre-treat with a commercial degreaser before pressure washing, which breaks down the oil in the concrete pores. Very old or deeply soaked stains may lighten considerably but not fully disappear. We'll give you an honest assessment upfront.
Why do Portland driveways get so mossy?
Moss grows wherever it finds moisture, shade, and organic material to anchor into. Portland's concrete driveways stay damp for much of the year, and porous concrete is a great host for moss spores. Driveways under tree canopy or on north-facing properties are especially prone. Once established, moss is slippery and makes the surface look neglected.
Will you damage my pavers or concrete?
No, when done properly. We adjust pressure based on the surface material — concrete handles higher pressure than pavers or stamped concrete. Older or damaged surfaces are assessed before we start, and we keep the nozzle moving to prevent etching. If there's something we're concerned about, we tell you before we start.
How long will a clean driveway stay clean in Portland?
In a full-sun location with good drainage, a cleaned driveway often looks great for 18–24 months before significant moss or algae returns. In shaded or damp areas, regrowth happens faster. An annual or biannual cleaning is the most practical maintenance schedule for most Portland homeowners.
