Pressure Washing
in Portland, OR
Driveways, Patios, Walkways & Fences
Driveway gone green and slick? Black grime on the patio, algae on the walkway? A wet Portland winter leaves every hard surface coated. We pressure wash concrete, asphalt, pavers, and fences with surface cleaners and eco-friendly detergents, and where high pressure would cause damage, like siding or roofs, we soft wash instead. The right method for each surface, never one machine for everything.

Why Portland's Hard Surfaces Turn Green — and Which Ones We Pressure Wash
Eight months of rain and shade grow moss, algae, and mildew on any surface that stays damp: concrete driveways, paver patios, retaining walls, wood fences, and walkways that turn into a slip hazard by January. Left alone, the growth holds moisture, stains permanently, and makes surfaces genuinely dangerous when wet.
The mistake most homeowners (and some inexperienced businesses) make is using one pressure setting for everything:
- Hard surfaces: concrete, asphalt, pavers, and stone get true pressure washing with a surface-cleaning machine after a detergent soak. Even, thorough, no wand stripes.
- Delicate surfaces: siding, painted wood, and windows get soft washing instead: low pressure plus a detergent that does the work.
- Roofs never get pressure washed, by us or anyone. High pressure strips shingle granules and can void your roofing warranty. Roofs get our soft wash roof cleaning only.
If you’re not sure which your job needs, send photos, and we’ll tell you in the estimate.

What Pressure Washing Costs in Portland
Most Portland pressure washing jobs run $300 to $600+, typically a driveway plus walkways and a patio. Your exact price depends on:
- Total square footage

- How much buildup has to come off
- Whether you add moss/algae inhibitor after cleaning
You’ll get an exact, itemized quote before we schedule anything, usually the same day. Send your address and a couple of photos; we measure the surfaces on Google Earth and email a complete cost breakdown.

Our 4-Step Pressure Washing Process
Every job follows the same documented process
We move furniture away from work areas and cover ponds, pools, and hot tubs before any washing starts
We clear loose moss and debris from the work area, then apply an environmentally friendly detergent that softens and breaks up the buildup before any pressure touches the surface.
Driveways, walkways, and patios get the surface-cleaning machine with pressure set for the material — an even, stripe-free clean. Decks and fences get a detergent soak and a handheld wand at the right pressure. Everything is rinsed clean.
We sweep and blow down the surrounding areas, apply moss/algae inhibitor where it's useful, and do a final walk-around before we leave.

Portland Pressure Washing Questions, Answered
Most jobs run $300–$600+ depending on square footage, surface type, and buildup. A typical driveway-plus-walkways job sits in the middle of that range. You get a free itemized quote, usually same-day, from Google Earth and your photos.
Power washing uses heated water; pressure washing uses ambient-temperature water at pressure. For most residential concrete in Portland, detergent plus a surface cleaner does the work without needing heat — the method matters more than the name.
For concrete, asphalt, pavers, and most stone — yes, at the correct pressure. Siding, painted wood, and windows should be soft washed instead, and roofs should never be pressure washed at all. We match the method to the material on every job.
No — and you shouldn’t let anyone. High pressure strips protective granules from shingles and can void your roofing warranty. For roofs we use a low-pressure soft wash; see our roof cleaning service.
In Portland’s damp climate, once a year keeps moss and algae from establishing — especially on shaded concrete. Adding inhibitor after cleaning stretches the time between visits.
Commercial surface cleaners wash evenly (no wand stripes), detergents do the heavy lifting at safe pressures, and the job that eats your whole weekend takes us a few hours — with cleanup included and a satisfaction guarantee behind it.
Yes — we can apply a moss/algae inhibitor to cleaned surfaces, backed by our 1-year moss-protection guarantee. For long-term stain protection on concrete, ask about sealing.
No. We need exterior access, a working spigot, cars moved off the surfaces being cleaned, and closed windows. We text you 30 minutes before arrival.
