House Washing Services in Seattle and Kitsap County, WA

Rain, moisture, and tree cover are part of life in the Pacific Northwest. Unfortunately, they also create the perfect storm for the buildup of green streaks on the siding, moss on the roof, and grime in all the hard-to-reach spots. Such a buildup looks ugly, eats away at paint, shortens the life of surfaces, and makes your home look neglected.

Homeowners across Kitsap County and Seattle, WA, trust Johnny Tsunami. We use soft washing techniques that protect your siding while removing every trace of dirt, mildew, and stains. Our biodegradable cleaners break down the mess, and our team brings years of local experience.

Your home deserves a better appearance. Let our professionals make it look new again.

Exterior Cleaning for Every Home

No matter what your home is made of, vinyl, wood, brick, Hardie board, or stucco, we’ve got the experience and the proper method to clean it safely. For new builds or 30-year-old family homes, we treat each surface with the care it deserves using chemistry that works and techniques that protect.

Restore Your Home's Beauty

Our siding wash doesn’t rely on pressure. We use purpose-built soft wash solutions that break down grime, algae, and mildew right at the root. This brightens your home’s exterior without damage, giving it that clean, polished look, like a refresh that adds years of life without lifting a paintbrush.

Results That Last

We don’t cut corners or crank up the pressure. Instead, we use biodegradable cleaners and low-pressure techniques tailored for each surface. It’s the safest approach for your siding, garden, paint, and roof.

Why House Washing Matters

Your Siding Faces a Lot More Than Rain
In the Pacific Northwest, homes constantly battle mold, algae, mildew, and grime, especially on shaded walls and north-facing surfaces. Over time, this buildup does more than make your house look dull. It slowly eats away at the very materials that protect your home.

If you leave it untreated, dirty siding can:

  • Trap moisture behind panels and seams
  • Cause paint to peel, fade, or chip early
  • Weaken wood, fiber cement, or stucco finishes
  • Create a breeding ground for pests and rot

Our soft wash siding service is built for long-term protection and eliminates the root of mold and algae without damaging your exterior.

Our 4-Step Professional House Washing Process

Extend your home’s life and restore its beauty with a precise soft wash method that removes algae, mold, and grime without damaging delicate surfaces.

Thorough Pre-Inspection

Before we touch a hose, we inspect every wall, trim, and corner to pinpoint buildup, stains, and vulnerabilities. This lets us customize our approach based on your home's specific materials and exposure.

Biodegradable Prep & Breakdown

We rinse away debris and apply a house-safe solution that targets organic growth like algae and mildew. It begins loosening grime while protecting paint, siding, and surrounding landscaping.

Safe & Powerful Soft Wash

Using low-pressure, high-efficiency tools, we rinse away years of buildup without risking your paint, wood, or siding. No streaks. No harsh blasts. Just a smooth, even clean that lasts.

Final Detail & Quality Check

We recheck every section, rinse away leftover residue, and walk the property with you if desired. Your siding shines, your trim pops, and your exterior looks refreshed, top to bottom.

Real Results, Happy Customers

See how our professional house washing has brightened homes and boosted curb appeal for families and businesses across the Pacific Northwest.

Signs It’s Time to Wash Your House

When your home’s exterior starts sending distress signals, it’s time to act. If any of the signs below sound familiar, your house is likely under attack from algae or mildew.

What We Look for During a House Wash

At Johnny Tsunami, we inspect your house with a trained eye to catch early signs of damage, grime, and wear. While on-site, our experts check for:
  • Mildew, Algae, and Moss Buildup
    We spot green or black growths that cling to siding and break down paint over time, and remove them before they cause costly damage.
  • Warped or Damaged Siding
    We inspect wood and Hardie board surfaces for swelling, cracks, or moisture pockets that signal hidden trouble. A professional wash can expose issues before they worsen.
  • Grime Trapped Around Vents and Windows
    These problem spots often collect unseen dirt and mold. We clean and inspect them to help keep your home healthier and looking sharp.
  • Rust Marks and Water Stains
    We catch and treat unsightly rust lines under gutters or fixtures. These are easy to miss, but we make sure they aren’t ignored.
