Who we are

Professional Home Exterior Soft Washing Services in Lake Oswego, OR

Lake Oswego homeowners expect quality service, and exterior cleaning is no exception.

NW Softwash brings over 1,500+ five-star Google reviews, licensed technicians, and a straightforward process that gets your home clean and keeps it that way.

We serve Lake Oswego with soft washing, roof cleaning, gutter cleaning, concrete cleaning, and window cleaning, all backed by written guarantees and a 30-minute quote response. Square footage pricing, no subcontractors, no surprises.

Lake Oswego winters are wet and overcast, with concentrated rainfall from November through March and December humidity regularly above 80 percent. The mature tree canopy throughout Hallinan, Palisades, and Lake Grove creates shaded conditions where moss and algae establish fast. Driveways, gutters, and siding take the same hit. Routine professional cleaning is the most cost-effective way to stay ahead of it.

Services

Exterior Cleaning Services We Offer in Lake Oswego, OR

Roof Cleaning

Roof Cleaning in Lake Oswego, OR

Soft wash roof cleaning removes moss, algae, and lichen using low-pressure application and an EPA-approved treatment that kills biological growth at the root. Lake Oswego’s dense tree coverage and persistent winter moisture let moss take hold fast and spread through a single wet season unchecked. High-pressure washing is not the answer. It strips granules, causes surface damage, and can void manufacturer warranties in one visit.

Every NW Softwash technician holds an Oregon State Department of Agriculture pesticide applicator license, a legal requirement for moss treatment that not every company bothers to carry. Roof cleaning is backed by a 1-Year Green-Free Roof Guarantee. Most Lake Oswego homes need professional service every 3 to 5 years, with heavily treed or lakeside properties often landing closer to 3.

House Soft Washing

House Soft Washing in Lake Oswego, OR

House soft washing clears algae, mold, and grime from siding without the surface risks of pressure washing. Lake Oswego’s shaded lots and long wet seasons mean siding discoloration builds steadily until it is hard to ignore. Our low-pressure system treats vinyl, Hardie board, stucco, brick, and wood with a biodegradable solution that breaks down growth at the biological level rather than rinsing the surface.

Backed by a 1-Year Green-Free Guarantee. Most Lake Oswego homeowners schedule a house wash every one to two years to stay ahead of the wet season.

Gutter Cleaning

Gutter Cleaning in Lake Oswego, OR

Gutter cleaning protects your foundation, fascia, and landscaping from overflow damage that builds fast in a city with concentrated winter rainfall. Lake Oswego’s mature trees shed heavy debris through fall and winter, and gutters that cannot clear that volume back up quickly. Our service clears every trough and flushes all downspouts to restore full drainage.

Every gutter cleaning includes our 14-Day No-Clog Guarantee. If anything backs up after we leave, we come back at no charge.

Driveway and Concrete Cleaning

Driveway and Concrete Cleaning in Lake Oswego, OR

Concrete cleaning restores driveways, patios, sidewalks, and pavers that accumulate moss, organic staining, and surface grime through Lake Oswego’s wet winters. Our service combines professional surface pressure washing with a biodegradable treatment that targets growth at the root. A surface-only wash removes the visible layer. Our treatment addresses what drives regrowth, so the results hold through the following season rather than reverting within weeks.

Window Cleaning

Window Cleaning in Lake Oswego, OR

Professional window cleaning removes hard water deposits, pollen, dirt, and grime from glass, frames, and screens in a single visit. Our pure water filtration system delivers a streak-free, spot-free finish without chemical residue. Exterior window and screen cleaning available. Lake Oswego’s wet winters deposit hard water build-up quickly, and clean windows make a noticeable difference in natural light and curb appeal on a property worth maintaining.

Had my gutters cleaned. It rained a few days later and I noticed a clogged down pipe. I emailed with a video. Two days later they came out and fixed the problem no questions asked. Always friendly and courteous. Thank you for your professionalism!!!

 Trustindex verifies that the original source of the review is Google. Excellent communication and scheduling throughout the entire process. Both Ford and Isiah were professional, customer-focused, informative, and highly knowledgeable about the roof cleaning service and what to expect afterward. They took the time to explain that while the moss has been successfully treated and is now dead, it will remain on the roof until it naturally loosens and falls away. After the first few rains, the remaining moss will begin to disappear on its own. I highly recommend this company based on the quality of their work, their attention to detail, and the exceptional care and service provided by their employees.

He restored both to looking brand new again. Isaiah also inspected our entire roof and attended to small areas of moss that he found as covered by our roof cleaning warranty.
