Meet Your Castle Keepers

Locally Owned • Professionally Trained • Castle-Worthy Clean

At Castle Soft Wash, we believe every home should be treated like a castle—protected, maintained, and kept beautiful for years to come. We're a locally owned and family-operated business based in the Pacific Northwest, proudly serving our neighbors in Cowlitz County with honest service, eco-friendly methods, and high-quality results you can count on.

We specialize in soft washing, a gentle alternative to traditional pressure washing that safely cleans your home’s exterior without damage. Using low-pressure, high-volume equipment and biodegradable cleaning solutions, we remove moss, mold, mildew, algae, dirt, and debris from roofs, siding, gutters, concrete, decking, windows, and more. Soft washing doesn’t just make your home look better—it protects its structure and extends its lifespan.

 Common Questions, Royal Answers

  • In the rainy, moss-loving climate of the Pacific Northwest, buildup on your home isn’t just an eyesore—it’s a risk. Left untreated, it can lead to rot, staining, leaks, and costly repairs. Soft washing safely treats and removes these problems at the root, without the harsh pressure that can damage shingles, siding, and delicate surfaces.

  • Absolutely. In fact, soft washing is the preferred method for cleaning asphalt shingles and vinyl siding. Our system is designed to kill and lift organic buildup without stripping protective layers or forcing water under surfaces.

  • Yes, we connect to your outdoor water spigot to supply the water needed for soft washing. Our custom system is highly efficient and uses low pressure and high volume, meaning it cleans thoroughly without wasting water. Most services use about as much water as a garden hose running for a couple of hours.
    If you use a well or have special concerns, just let us know—we’re happy to work with your setup.

  • Most customers enjoy 12 to 24 months of clean surfaces, depending on your home’s exposure to shade, moisture, and nearby trees. Regular soft washing prevents buildup from returning and helps maintain the value and beauty of your home.

    For roofs, a full soft wash is typically needed every 2 to 3 years, or sooner if moss or algae return. Gutters should be cleaned at least once a year, ideally before the rainy season.

  • After a soft wash, you’ll notice an immediate improvement in appearance—black streaks, moss clumps, and discoloration will be gone or visibly reduced.
    If heavy moss was present, some residual browning or dying moss may remain for 1–2 weeks but will naturally wash away with rain or fall off as it dies.
    We treat the roof with a moss-killing solution that continues working over time and helps prevent regrowth. You’ll be left with a cleaner, healthier roof that’s protected from long-term damage.

  • Yes! We use biodegradable, eco-friendly cleaning solutions that are safe for your family and landscaping. Our bleach-based solution is carefully diluted enough to break down into harmless salt, which safely returns to the earth without harming the environment. To protect your plants and flowers during cleaning, we also cover them as needed to ensure they stay safe and healthy.

  • We do! We remove debris from inside your gutters and flush the downspouts to ensure proper drainage. Then we soft wash the exterior, removing black streaks and grime so your gutters work—and look—like new.

  • Yes! We offer streak-free window cleaning that restores clarity and shine to both your glass and frames. Whether you need a full house refresh or a seasonal touch-up, we’ve got your view covered.

  • Not necessarily. As long as we have access to the areas being cleaned and a working water source, we can take care of everything while you’re away. We’ll send photos and updates for peace of mind.

  • Pricing depends on the size of your home and the services needed. We offer free, no-obligation quotes and are happy to walk your property with you or provide a virtual estimate.

  • It’s easy!
