What does pressure washing cost in Corvallis?
Before you ask for a number, it is worth reading what actually moves an Oregon quote.
Pressure washing in Corvallis starts at $299, and each property is priced on its square footage, stories, surface and access rather than from a per-square-foot or hourly chart. A driveway takes 1 to 2 hours on site, a two-story house wash 3 to 4, and the written quote is the invoice.
A flat-lot rambler and a hillside two-story are not the same job. Here is what we clean, and roughly how long each takes.
- Driveway and concrete cleaning 1 to 2 hours
- Sidewalks and walkways About 1 hour
- Patio cleaning 1 to 2 hours
- House washing, single story 2 to 3 hours
- House washing, two story 3 to 4 hours
- House washing, large or complex 4 to 5 hours
- Roof treatment, composition shingle 3 to 5 hours
- Roof treatment, cedar shake 4 to 6 hours
- Gutter cleaning 1 to 2 hours
- Deck cleaning 2 to 3 hours
- Fence cleaning 2 to 3 hours
- Complete exterior package 1 to 2 days
Every quote is written and itemized before work begins, and the price on the quote is the price on the invoice. Send the address through the form and the itemized number comes back within 24 hours.
Why Corvallis homes need cleaning more often
Corvallis averages about 43 inches of rain across roughly 157 days. December alone brings 7 to 8 inches, and surfaces stay damp from October through May.
That moisture feeds moss, algae, and mildew, so exterior cleaning matters more here than it does in drier parts of the state.
The damage runs deeper than looks. Moss holds water against roofing and lifts shingle edges. Algae turns concrete slick well before it looks dirty. And mildew penetrates siding if it sits through two wet seasons.
Because treatments need dry surfaces to bond, the useful window runs late May through September. Work booked inside it costs the same and lasts longer. That said, we take emergency and pre-sale jobs year-round.
What changes a Corvallis pressure washing quote
Every exterior cleaning company in Corvallis tells you to schedule an estimate. But here is what that estimate measures. That way you can work out roughly where your property lands before anyone visits.
Cost drivers, line by line
| Component | What we use | Why it matters here |
|---|---|---|
| Square footage | The single largest factor | It drives time on site, and time is what you pay for |
| Number of stories | A second story adds more than its area | Ladder work and extension gear slow the safe pace on every elevation |
| Years since the last clean | Adds most on a first visit | Three Corvallis winters takes two passes; annual upkeep takes one |
| Surface type | Stamped concrete and cedar cost more | Reduced pressure means slower work, and sealed surfaces need gentler chemistry |
| Access | Gates, slopes, and long carries add time | Hillside lots off Witham Hill are the common Corvallis case |
| Water source | A working outdoor spigot at decent pressure | No supply means we haul water, and that changes the job |
| Tree canopy | Heavy canopy adds gutter and roof work | Witham Hill, College Hill, and Avery Park carry the most debris |
| Bundling services | Cuts the cost per service | One setup across several surfaces beats separate visits through the year |
| Multiple properties | Cuts the cost per address | We quote them together instead of pricing each as an unrelated job |
| When you book | Late May to September is efficient | Shoulder-season work takes longer, and the result does not hold as well |
How booking works in Corvallis
-
First, send the address
Tell us the Corvallis address, plus the address and which surfaces need attention. Two minutes on the form, no phone call, and nobody walks your property before you have a number.
-
Then a written quote, inside 24 hours
Your itemized quote arrives by email, broken out by surface, square footage and story height, valid for 30 days.
-
Once you approve it, we schedule
Pressure is matched to each surface before anything is switched on, and we tell you which setting goes on your siding and why that number.
-
Finally, the quote is the invoice
Chris does the work himself, so the person who quoted it is the person on site. Payment is due on completion, with every surface walked with you in daylight.
Can pressure washing water go into a Corvallis storm drain?
Not if it carries pollutants. The City of Corvallis treats water carrying fertilizer, pesticides, oil, antifreeze, pet waste or paint into a storm drain as an illicit discharge, and Municipal Code Section 4.04 makes dumping waste into a storm drain illegal.
Clean rinse water is the simple case. Degreaser, detergent and moss treatment are collected on site rather than sent down the curb, and the written quote states that.
The city's stormwater pollution prevention team leads with education but will use its legal authority on violators, and it runs a 24-hour hotline for reports. Where the water goes is worth asking any company before the work starts, not after.
The Corvallis rental calendar
ZIP 97331 is the OSU campus. As a result, a large share of local housing turns over on the academic lease cycle instead of the seasonal one. If you own rentals here, this is your year.
Book the summer work
Leases end and units empty out. The dry window opens at the same time. Because the calendar is still open, this is the cheapest and most flexible point to schedule.
Turnover cleaning
Units sit empty and access is unrestricted. Surfaces dry fast enough for treatments to bond. So exterior work finishes before the September rush.
The crunch
Move-in week. Most trades in town are booked, and the first fall rains usually arrive mid-September. Work still gets done. But you get less choice of date and more weather risk.
Gutters, before the rain
Leaf drop finishes. Gutters cleared now prevent the overflow and fascia problems that become tenant complaints in December.
Maintenance and planning
Too wet for most exterior work to last. The useful job here is therefore walking the portfolio and booking next summer while the calendar is open.
Concrete is the easy part
Almost any machine will move dirt off a concrete driveway. The skill in this trade is in everything that is not concrete.
Vinyl siding needs soft washing under 500 PSI, because high pressure forces water behind the panels. We never pressure wash composition roofs at all. It strips the granules that shield the shingle from UV.
Stamped concrete loses its sealer above roughly 2,000 PSI. Cedar raises grain and never recovers. A generalist with one setting therefore leaves you a clean driveway and damage that surfaces months later.
Ask any Corvallis contractor one question before you hire. What pressure will you use on my siding, and why that number? If the answer is vague, they have not decided yet.
Rental properties in Corvallis
Corvallis is a university town, and ZIP 97331 is the campus itself. So the rental market runs differently from owner-occupied housing. Turnover is scheduled, not seasonal. Owners hold several properties. And many of them do not live nearby.
Because of that, we schedule turnover cleaning around the August and September lease cycle. Units sit empty and access is straightforward. Multi-property owners get one itemized quote covering every address.
We photograph every job before and after. That matters when the person approving the invoice never walked the property.
Common rental work here: driveways and walkways between tenancies, house washing on the two to three year cycle most landlords budget for, gutters before the October rains, and decks where units have outdoor space.

Corvallis neighborhoods we serve
Witham Hill
Elevated west-side lots under heavy Douglas fir. North-facing siding holds moisture longest. These homes therefore want house washing every year rather than every other.
Timberhill
Newer north Corvallis subdivisions, mostly vinyl and fiber cement. We soft wash these under 500 PSI, because high pressure forces water behind the panels.
College Hill
Older housing near campus with mature trees and many rentals. Gutter loading runs heavy through October. And turnover cleaning peaks in late summer.
South Corvallis
The Willamette keeps humidity up and stretches the damp season. As a result, older concrete here shows the deepest organic staining in the city.
Country Club and Central
Larger established properties and historic homes. Brick, painted wood, and original trim need a gentle-pressure look before we start.
Avery Park and Job's Addition
River-adjacent, older housing, heavy canopy. Roof and gutter work dominates here.
Northwest Corvallis and Bald Hill
Newer construction on sloped lots. Runoff concentrates on driveways and lower walkways. That means concrete needs cleaning more often than it does on flat lots.

Common questions
Pressure washing in Corvallis starts at $299. We quote each one individually, because square footage, story height, surface condition, and access move the number more than a published chart can.
A single-story rambler with a short driveway and a two-story with cedar siding are not the same job. Send your address through the form. We return an itemized written quote within 24 hours, valid 30 days, and the quote price is the invoice price.
We cover every Corvallis neighborhood across ZIP codes 97330, 97331, 97333, and 97339. That includes Witham Hill, Timberhill, College Hill, South Corvallis, Country Club, Central Corvallis, Avery Park, Job's Addition, Northwest Corvallis, and Bald Hill. Philomath sits 6 miles west at the same rates.
We charge no travel surcharge anywhere in Benton County. And we do not zone price between neighborhoods. A hillside lot off Witham Hill and a flat lot in Timberhill are therefore priced on the work, not the address.
Most Corvallis homes need house washing once a year and gutter cleaning twice. Driveways benefit from annual cleaning. And properties under heavy canopy often need more.
Corvallis sits at the high end of Oregon's maintenance frequency, because of the 43 inches of rain and the long damp season. Homes in Witham Hill, College Hill, and Avery Park sit under dense canopy. That puts them on three clearings a year rather than two.
North-facing surfaces colonize with moss fastest, because they stay shaded. Newer properties in Timberhill manage fine on an annual cycle.
Not at full pressure. Vinyl, fiber cement, stucco, cedar, and painted wood all need soft washing under 500 PSI with cleaning solution instead of high-pressure water.
High pressure on vinyl forces water behind the panels. On cedar it raises the grain and strips finish. And on stucco it removes surface material outright.
High pressure between 2,500 and 4,000 PSI belongs on concrete, brick, and stone. Siding gets soft washing. Any company using one setting across a whole property is doing it wrong.
Square footage is only the starting point. A second story adds more than its area because ladder work slows every elevation, and surface type, access and years since the last clean all move the number.
On time alone, a single-story house wash takes 2 to 3 hours and a two-story 3 to 4. Work starts at $299, and the itemized written quote comes back within 24 hours.
Not for cleaning alone. The Oregon Construction Contractors Board lists power and pressure washing for the purpose of cleaning siding, sidewalks and similar surfaces among the work that does not require a license.
Oregon law generally requires a license for construction work that improves real property, so ask for a CCB number if a quote goes beyond cleaning.
No. We complete most Corvallis jobs without the owner present. That is why we photograph every job before and after.
We need access to an outdoor water spigot and to any gated areas. For rentals and absentee owners this is the normal arrangement. The photographs and the itemized invoice are your record of what we did.
Yes. But book it early. Corvallis turnover clusters into late August and September, and trades across town fill up that month.
Rental work booked in May or June for July execution gets better weather, better scheduling, and better pricing. Multi-property owners receive one written quote covering every address.
Most single services run one to four hours. A driveway or patio usually takes one to two hours. House washing runs two to four depending on stories. And a complete exterior package runs one to two days.
The written quote states the expected duration for your property. Anything running longer than a day is therefore scheduled with you in advance, rather than discovered halfway through.

Photos help, but we do not require them. For multiple properties, list every address and one quote covers them all.
One heats the water and one does not, which is the whole of the technical difference. On its own that distinction does not move a Corvallis quote.
What moves the number is on this page already: area, story height, surface type and access. A second-story elevation reached from a ladder costs more than the same square footage at ground level whatever the water temperature, and a surface that must be soft washed is priced by dwell time rather than by machine. Ask any contractor to put the method for each surface in writing, which is what an itemized quote is for.
