Driveway and Concrete Cleaning in Oregon

A two-car driveway runs $150 to $250. Adding walkways and a patio takes it to $200 to $350, and a full hardscape package covering every hard surface on the property runs $300 to $500. Those are average Oregon market rates. We quote per property after a walkthrough and lock the figure in writing, with no trip fee inside the service area.

Because the crew used a wand instead of a rotating surface cleaner. A wand cleans in a narrow arc, so overlapping passes leave visible bands across the slab that show most in low winter sun. A surface cleaner covers a fixed circle at constant distance and produces an even finish. Stripes are permanent in the sense that the only fix is cleaning the whole slab properly.

Concrete takes 2,500 to 4,000 PSI, which is the highest pressure used anywhere on a property. Pavers and flagstone sit at the lower end because pressure blows out the joint sand. Stamped and decorative concrete needs lower pressure again to protect the sealer. Anything overhead or painted, by contrast, must drop below 500 PSI.

Usually, though it depends on age. Fresh oil lifts with a degreaser and hot detergent. Oil that has sat for years has penetrated the concrete rather than resting on it, so a significant improvement is realistic and complete removal often is not. We say which outcome to expect at the quote rather than after the work.

Once a year for most Oregon properties, and twice for north-facing slabs or driveways under tree cover. The wet season runs October to May here, which gives algae a nine-month growing window. That green film holds water on the surface and is what makes a driveway slippery rather than simply dirty.

Yes, and booking them together costs less than separately because it is one setup. Patios, walkways, steps, entryways, pavers and flagstone are all covered. Pavers use lower pressure to protect the joint sand, and we re-sand where the original joint has already washed out.

Yes. Commercial concrete cleaning covers parking areas, walkways, loading zones and dumpster pads, quoted against a written scope with area and frequency. Commercial flatwork needs run-off containment rather than a rinse to the kerb, because the volume is higher and Oregon DEQ regulates what enters the storm system.

Not at the correct pressure with the correct tool. Damage happens when a wand is held too close, which etches lines into the surface, or when pressure is used instead of pre-treatment to lift growth. Sound concrete handles 2,500 to 4,000 PSI from a surface cleaner without issue. Older or already spalling concrete gets lower pressure and a longer dwell instead.

Autumn, and it is the visit most people skip. Stripping the algae film off a driveway, walkways and steps before the rain returns is a safety job rather than a cosmetic one, because those surfaces stay wet from November until May. Spring is the second-best window and clears whatever built up over winter.

No. We clean concrete and refer sealing to a contractor in that trade, because sealing is a coating application rather than a cleaning service. Anyone offering both in the same visit is usually rushing one of them, and a sealer applied before the slab is fully dry traps moisture underneath.
