Your home’s siding is more than just a pretty face — it protects everything underneath from moisture, weather, and wear. But in our damp Pacific Northwest climate, it doesn’t take long for algae, mildew, and grime to settle in. Our soft washing process gently removes this buildup without damaging paint, wood, or other delicate surfaces. Whether your siding is vinyl, wood, fiber cement, or stucco, we tailor our method to clean it thoroughly and safely.

At Snohomish Pressure Washing, we treat each home with care, using eco-friendly cleaning solutions and low-pressure equipment that gets great results without harsh impact. We don’t just wash your house — we restore its appearance and extend its life.

Bigfoot-tough cleaning. Small town service.

Why clean your home’s exterior?

Even if your siding looks fine at a glance, buildup happens slowly — and the long-term effects can be costly. Soft washing is a safe, effective way to stay ahead of damage.

Protect Your Siding
Algae, mildew, and grime trap moisture and wear down your siding’s protective layer over time.

Boost Curb Appeal
A freshly cleaned home looks brighter, newer, and more welcoming — great for pride, photos, or prepping to sell.

Prevent Long-Term Issues
Soft washing helps prevent mold, staining, and premature surface breakdown that can lead to costly repairs.

Risks of not cleaning your siding

We get it. Taking care of a home is hard work — maybe letting it slide one more year wouldn’t be that big a deal…what’s the worst that could happen?

  • Moisture gets trapped in organic buildup, leading to mold growth and wood rot
  • Dirt and pollutants wear down paint, coatings, and finishes
  • Mold and mildew can spread to windows and soffits
  • Curb appeal drops, and so can property value

Residential services

Your home is one of your biggest investments, and keeping it clean helps protect that investment. We soft wash siding, trim, soffits, garage doors, and even second-story areas that most homeowners can’t safely reach. Whether you’re getting ready for spring, listing your home for sale, or just tired of looking at green streaks and dark smudges, we’ll help your home look refreshed and well cared for — all without risking damage to paint, landscaping, or windows.

Commercial services

Your storefront or commercial building is part of your brand, and first impressions matter. We offer soft washing for building facades, signage, entryways, and awnings, all using low-pressure methods that safely clean delicate materials. Whether you manage a retail space, a professional office, or a small multi-tenant complex, clean exteriors help create a more professional, welcoming experience for customers and tenants alike. We’ll even schedule service outside of business hours.

Frequently asked questions

Soft washing uses low-pressure water combined with specialized cleaning solutions to gently remove dirt, algae, mildew, and mold from your home’s siding. Pressure washing, by contrast, uses high-pressure water that can damage siding, strip paint, or force moisture behind panels. That’s why we use soft washing for most house exteriors — it’s safer, cleaner, and longer-lasting.
Not at all. Soft washing is designed specifically for delicate surfaces like painted siding, wood, and stucco. We adjust our pressure levels and cleaning solutions based on your home’s surface to ensure a thorough clean without any risk of damage. It’s safe, surface-friendly, and much gentler than DIY pressure washing.
For most homes in the Pacific Northwest, we recommend washing the exterior every 1–2 years. That’s enough to keep organic buildup under control and protect your siding from moisture-related damage. Homes in shaded, wooded, or high-traffic areas may benefit from more frequent cleanings.
We can safely clean virtually all siding types, including vinyl, painted wood, fiber cement (like HardiePlank), composite materials, stucco, and aluminum. Each material is evaluated before we begin, and we tailor our approach to ensure effective, safe results.
Yes, we use biodegradable, eco-friendly cleaning solutions that are effective on grime but safe around pets and landscaping when applied responsibly. We also rinse plants before and after cleaning and cover sensitive vegetation as needed to provide extra protection.
Nope! As long as we have access to the exterior water supply and all windows and doors are closed, you don’t need to be home during the service. We’ll confirm details with you ahead of time and keep you updated before, during, and after the job.
Most house washing jobs take between 2 to 4 hours, depending on the size of the home and the level of buildup. Larger homes, second-story work, or areas with heavy moss or mildew may take a bit longer, but we’ll give you a clear time estimate before we begin.
