Final pricing depends on square footage, story height, surface condition, and access. Every quote is written and itemized before work begins, and the price on the quote is the price on the invoice. What changes your price, and what we never charge extra for.
Pressure washing and the year-round work
Roofline and seasonal work
Pressure washing every Lake Oswego, Oregon neighborhood
Lake Oswego is not one cleaning problem. Canopy, elevation, water proximity, and the age of the siding change what a property needs and how it gets quoted.
First Addition and Old Town
Lake Oswego's oldest housing stock, including individually recognized historic properties. Original painted wood siding, ornamental trim, and single-pane windows in original frames. Gentle pressure and hand detailing throughout.
Mountain Park
Planned community in the hills with a high share of townhomes and condos. Shared walls and HOA common areas mean scheduling and a certificate of insurance matter as much as the cleaning.
Forest Highlands and Country Club
Mature Douglas fir canopy over established homes. The heaviest roof and gutter loading in the city, and north-facing walls hold moss longest. Usually a three-times-yearly gutter cycle rather than two.
Lake Grove and Lake Forest
West of Oswego Lake near I-5, older developments mixed into newer construction. Wide variety of siding ages on one street, so method is set per property rather than per neighborhood.
Palisades and Hallinan Heights
South of the lake, hilly, heavy tree cover. Sloped lots concentrate runoff onto driveways and lower walkways, which need concrete cleaning more often than flat-lot properties.
Westlake and Westridge
Western edge near Kruse Way. Newer construction with more vinyl and fiber cement siding, which means soft washing under 500 PSI. High pressure forces water behind the panels.
Uplands and Waluga
Northern Lake Oswego between Boones Ferry and the Country Club corridor. Established homes, mixed surfaces, mature landscaping. Complete exterior packages are common.
Blue Heron, Lakewood and Evergreen
Waterfront and near-water properties around Lakewood Bay and the canals. Constant ambient humidity keeps surfaces damp past the point where inland lots dry out, and algae returns fastest here.
McVey-South Shore and Glenmorrie
South shore and out toward Marylhurst near the Willamette. Larger private lots, long driveways, significant hardscape. Access and drive length affect the quote more than square footage does.
Bryant, Childs and Rosewood
South end toward Rivergrove. Mixed housing ages on larger lots with outbuildings, fencing, and detached garages that get forgotten until the house is clean and they are not.
Oak Creek, Skylands and Holly Orchard
Established residential with dense canopy and older concrete. Deep organic staining on driveways is typical and comes out with a surface cleaner rather than more pressure.
Foothills and the Willamette riverfront
Riverfront exposure, mixed residential and commercial. Humidity and river fog extend the damp season on the east side of the city.
Correct pressure for every surface
This is the reference we work to on every property. It is published because most damage in this trade comes from one setting being used everywhere, and because you should be able to check what anyone is about to do to your house.
Surfaces that must never see high pressure
| Surface | Method | Pressure | Why it matters |
|---|---|---|---|
| Vinyl siding | Soft wash | Under 500 PSI | Pressure forces water behind panels |
| Fiber cement (HardiePlank) | Soft wash | Under 500 PSI | Pressure drives water into board edges and seams |
| Stucco and EIFS | Soft wash | Under 500 PSI | Pressure removes surface material permanently |
| Painted wood siding | Soft wash | Under 500 PSI | Pressure strips paint and raises the grain beneath |
| Cedar shingle or shake siding | Soft wash | Under 500 PSI | Pressure raises grain, strips finish, shortens service life |
| Composition shingle roof | Chemical only, never pressure | Under 100 PSI rinse | Pressure strips the granules that shield shingles from UV |
| Cedar shake roof | Chemical only, never pressure | Under 100 PSI rinse | Same fiber damage, and a far higher repair cost |
| Windows and glass | Soft wash or hand detail | Under 500 PSI | Pressure at the seals drives water into the frame |
| Vinyl or aluminum fencing | Soft wash | Under 500 PSI | Same failure mode as vinyl siding |
| Gutter exteriors | Soft wash | Under 500 PSI | Pressure dents aluminum and drives water behind the fascia |
Surfaces that tolerate pressure, and how much
| Surface | Method | Pressure | Why it matters |
|---|---|---|---|
| Modern brick, Portland cement mortar | Pressure | 1,500 to 2,500 PSI | Tolerates moderate pressure when the mortar is sound |
| Historic brick, lime mortar | Low pressure, assess mortar first | Under 800 PSI | Lime mortar is softer than the brick and washes out of joints |
| Concrete driveway and walkway | Pressure with surface cleaner | 2,500 to 4,000 PSI | A surface cleaner gives an even result; a wand leaves stripes |
| Stamped or decorative concrete | Reduced pressure | 1,200 to 2,000 PSI | Full pressure removes the sealer and dulls the color |
| Paver patio | Pressure, then re-sand | 1,500 to 2,500 PSI | Cleaning removes joint sand; it must be replaced afterward |
| Natural stone | Reduced pressure | 800 to 1,500 PSI | Softer stone erodes and the damage is permanent |
| Wood deck | Reduced pressure, with the grain | 500 to 1,200 PSI | Across the grain or too close leaves permanent wand marks |
| Composite deck, Trex and similar | Reduced pressure, fan tip | Under 1,500 PSI | Most composite warranties specify a pressure ceiling |
If a contractor cannot tell you which setting they will use on your siding before they start, they have not decided yet.
Soft washing and pressure washing in Lake Oswego, Oregon are not the same thing
The most expensive mistake in this trade is using one pressure setting across a whole property. It is also the most common, because it is faster and the damage does not show up on the day.
Pressure washing uses high-pressure water, typically 2,500 to 4,000 PSI, so the force itself does the cleaning. That is correct for concrete, sound brick, and stone, though for little else.
Soft washing uses low pressure under 500 PSI with a cleaning solution that kills organic growth at the root, and the water only rinses. That is correct for every type of siding, every roof, windows, fencing, and anything painted or coated. It also lasts longer, because pressure removes what you can see while the solution removes what would otherwise regrow.
Getting it wrong is expensive, and the bill arrives late. High pressure on vinyl forces water behind the panels and into the wall. Similarly, on a composition roof it strips the granules that protect the shingle and takes years off its life. On stucco, meanwhile, it removes surface material permanently. None of these are visible the day the crew leaves. All of them cost more than the cleaning did.
Almost every property needs both methods, because almost every property has both kinds of surface. So the reference above is what we actually work to.
Why Lake Oswego properties need cleaning every year
The Portland metro receives roughly 44 inches of rain a year across about 155 days, with December and January the wettest months. Lake Oswego sits under heavy Douglas fir and big leaf maple canopy, and the city is built across hills and around a lake, both of which hold moisture.
Consequently moss, algae, and mildew grow faster here than almost anywhere else in the country. Surfaces stay damp from October through May, and shade blocks the UV that would otherwise slow algae growth, so north-facing walls and roof planes under canopy stay biologically active nearly year-round.
Notably, the damage is structural rather than cosmetic. Moss holds water against roofing and lifts shingle edges until water gets underneath. Algae on concrete likewise becomes a genuine slip hazard well before it looks bad enough to notice. Mildew penetrates siding if it sits through more than one wet season, and past that point cleaning reveals the staining rather than removing it.
Finally, the reliable dry window runs late May through September. Treatments bond properly only when surfaces dry fully between application and rain, so work scheduled inside that window costs the same and lasts materially longer.

Why people hire Chris
The owner does the work
Chris founded Westview Services in 2022 and still runs the jobs himself rather than dispatching crews. The person who quotes your property is the person who cleans it, which is why the quote and the result match.
Pricing in writing, before anyone arrives
We itemize every quote and send it before work begins. No mid-job upsells, no scope creep, no invoice that lands higher than the number you approved.
Method matched to the surface
Vinyl, fiber cement, cedar, stucco, brick, and stamped concrete each need different pressure and chemistry, so one setting cannot serve them all. Using one setting across a whole property is the most common way a cheap wash turns into a repair bill.
No cold calls, ever
Quotes come by email and stay there. You decide on your own schedule, without someone following up three times to close you.
The guarantee
If any surface is not cleaned to your standard, Chris returns within seven days and makes it right at no cost. That applies to every job, in every city we serve, with no form to file and no argument about it.

When to schedule pressure washing in Lake Oswego, Oregon
Oregon gives you a narrow window for most exterior work. Scheduling inside it costs the same and lasts longer.
Windows and holiday lights
Glass is at its dirtiest after a dry summer, and clear windows matter most heading into the darkest months. Holiday lights go up in the same stretch of weeks, before the weather turns. Booked together, that is one visit instead of two.
Gutters, before the heavy rain
Leaf drop finishes and the rain starts. Gutters cleared now prevent the overflow and foundation problems that show up in December.
Light takedown and a second gutter clear
Takedown is already included in every holiday lighting price. It is also the natural time to clear whatever the autumn left behind.
Pressure washing and roof moss
This is the only reliable dry window in Oregon. Treatments bond properly and last longer when surfaces dry fully between application and rain.
Common questions
Projects start at $299. Every property is quoted individually, because square footage, story height, surface type, and access change the price more than any published chart can account for.
For example, a 900-square-foot single-story rambler and a two-story home with cedar siding and a steep roofline are not the same job. Pricing them alike would mean overcharging one and losing money on the other. Send the address through the form and an itemized written quote comes back within 24 hours, valid 30 days.
Westview Services works from Lake Oswego across the Portland metro, including West Linn, Tualatin, Tigard, SW Portland, Beaverton, Oregon City, and Milwaukie. Pricing is likewise the same in every metro city, with no travel surcharge.
In the southern Willamette Valley, Westview serves Corvallis, Albany, and Eugene, plus Philomath and Springfield. Window cleaning and holiday light installation are additionally available in Eugene.
No, not at full pressure. Instead, vinyl, fiber cement, stucco, cedar, and painted wood all need soft washing under 500 PSI with cleaning solution rather than high-pressure water.
High pressure on vinyl forces water behind the panels. On cedar, similarly, it raises the grain and strips the finish. On stucco it removes surface material. High pressure between 2,500 and 4,000 PSI therefore belongs on concrete, brick, and stone. Any company using one pressure setting for the whole property is doing it wrong.
Once a year for house washing and pressure washing, and twice a year for gutter cleaning, is right for most Oregon properties. Windows, meanwhile, benefit from two to three cleanings a year.
Oregon's long wet season and heavy tree canopy push maintenance frequency above the national norm. North-facing surfaces colonize with moss fastest, since they stay shaded and damp. Properties under mature canopy often need gutters cleared three times a year rather than two.
Late May through September for pressure washing and roof treatments, because that is the only stretch when surfaces dry fast enough for treatments to bond properly.
Windows and holiday lights, by contrast, are best done in September and October. Gutters are best done in late October after leaf drop, and again in January. Work scheduled inside the right window costs the same and lasts longer.
Westview Services works from Lake Oswego itself, so every neighborhood in the city is a short drive: First Addition, Old Town, Mountain Park, Forest Highlands, Lake Grove, Lake Forest, Palisades, Hallinan Heights, Westlake, Westridge, Uplands, Waluga, Blue Heron, Lakewood, Evergreen, McVey-South Shore, Glenmorrie, Bryant, Childs, Rosewood, Oak Creek, Skylands, Holly Orchard, and Foothills.
Beyond the city the same pricing applies across West Linn, Tualatin, Tigard, Portland, Beaverton, and Oregon City, and in the Willamette Valley in Corvallis, Albany, and Eugene. There is no travel surcharge in any of them.
Pressure washing uses high-pressure water, typically 2,500 to 4,000 PSI, so the force itself does the cleaning. Soft washing uses low pressure under 500 PSI with a cleaning solution that kills organic growth at the root, and the water only rinses.
Pressure washing is correct for concrete, sound brick, and stone. Soft washing is correct for all siding, all roofing, windows, fencing, and anything painted or coated. Most properties need both, which is why a company that uses one setting everywhere is doing it wrong.
No. Roofs are never pressure washed. Composition shingle and cedar shake roofs are treated chemically and rinsed at under 100 PSI.
Pressure strips the mineral granules that protect asphalt shingles from UV, which takes years off the roof and cannot be reversed. Any company offering to pressure wash your roof is offering to damage it. Correct roof moss treatment kills the moss at the root, so it does not regrow from roots left behind.
Not when the pressure matches the surface. Poured concrete handles 2,500 to 4,000 PSI with a surface cleaner. Stamped or decorative concrete needs 1,200 to 2,000 PSI, because full pressure removes the sealer and dulls the color.
Pavers clean at 1,500 to 2,500 PSI, but cleaning removes the joint sand and it has to be replaced afterward. Any company that cleans pavers and does not re-sand has left the job half done. Natural stone is softer and runs at 800 to 1,500 PSI.
Yes. Certificate of insurance is available on request, which Mountain Park and the other Lake Oswego HOA communities generally require on file before work begins.
Multi-property owners and managers receive a single itemized quote covering every address rather than separate estimates. Every job is documented with before and after photographs, which matters when the person approving the invoice has not walked the property.
No. There is no deposit for standard residential work, and payment is due on completion after you have walked the property and confirmed you are satisfied.
Larger custom projects and commercial contracts can be structured with progress payments if that suits you better. Certificate of insurance is available on request for HOAs, property managers, and commercial clients.
Chris returns within seven days and makes it right at no charge. That applies to every job in every city we serve.
There is no claim form and no argument about whether it qualifies. If a surface is not cleaned to your standard, say so and it gets redone.
