Algae film, tire marks, and oil are removed by different means, and a single pass at high pressure handles only the first. In addition, roofs and painted siding get low-pressure soft washing with the right solution and the right dwell time. Pressure that is correct for a concrete driveway will strip paint, force water behind cladding, and void a siding warranty. Concrete and stone get calibrated pressure. Surface cleaning that leaves an even finish instead of the wand stripes that a cheap job leaves behind. That decision gets made surface by surface on your property, not from a truck.
Access shapes the rest: Portland means narrow inner-city lots where staging. Runoff control take more planning than the wash. All of it is scoped during the walkthrough before a number is written, which is why the quote is all-inclusive. What is quoted is what you pay.

A driveway does not fade evenly. The shaded side greys first, tire tracks stay darker, and the drip line under the eave grows a distinct black band. That pattern is the tell that you are looking at biological growth rather than accumulated dirt, and it explains why a garden hose never seems to fix it.
The other half of the problem is oil. Engine drip soaks into the pores of concrete, and a surface rinse floats the top layer while leaving the stain. Degreaser and dwell time pull it out, which is why a proper driveway cleaning is a two-stage job on any slab that has parked a car for more than a few years.
Stripes are the most common complaint about a cheap driveway job, and they are permanent in the sense that the only fix is cleaning the entire slab again to match. The prevention is a rotating surface cleaner, correct pressure for the concrete age, and consistent travel speed. It is unglamorous work and it is the whole difference in the result.
Sealing is a separate question. A clean slab can be sealed to slow regrowth, but sealing over a dirty or damp slab traps the problem underneath. If sealing is on your list, the cleaning comes first and the slab needs to dry.
The method follows the material, and getting that wrong is what leaves a driveway looking worse than before it was cleaned.
Staining matters as much as surface. Algae film, tire marks, oil and rust each need a different treatment, and a single pass at high pressure only addresses the first.
You can, and for a small patio it is reasonable. The limitation is equipment rather than skill: consumer machines run roughly 2,000 to 2,700 PSI through a single wand, and a wand cleans in arcs. That is where the striping comes from, and stripes are permanent until the whole slab is cleaned evenly. A rotary surface cleaner covers the full width at a constant distance, which is the difference you are actually paying for. The other one is what happens to paver joints afterwards, because rented machines do not come with replacement jointing sand.
A good share of driveways in this metro are asphalt rather than concrete, and the two do not take the same treatment. Asphalt is a flexible surface held together by bitumen, and the binder is what fails first.
If the driveway is sealcoated, say so when you call – sealer changes what can be used on it, and a wash that would be right on bare asphalt can strip a fresh coat.

A driveway is the one surface where a homeowner can usually judge the quote themselves, because the area is easy to measure and the method is not in question. What is worth asking is what happens at the edges: the apron where the drive meets the street, the strip against the garage door, and whether oil staining is being treated or simply rinsed around. Those three are where a cheap driveway quote is usually cheap.
