Signs It’s Time to Wash Your House

Your home’s exterior can collect dirt, algae, mildew, pollen, and other buildup long before it looks seriously dirty. If you notice any of these signs around your Bellevue home, it may be time for professional house washing.

Green Algae or Mildew Growth

Green patches, discoloration, and organic growth on your siding are common signs that moisture and environmental buildup are taking hold. Professional house washing can remove this buildup and help keep your exterior looking well-maintained.
Dark streaks and water stains beneath roof gutters

Dark Streaks and Surface Stains

Dark streaks and stains can develop across siding, particularly beneath gutters and around areas exposed to ongoing moisture. Removing these stains can restore a cleaner, brighter appearance to your home.
Spider webs and debris around exterior trim

Cobwebs and Buildup Around Trim

Eaves, trim, corners, and entryways can collect cobwebs, pollen, insect debris, and other buildup over time. These areas are easy to overlook but can make an otherwise clean home look neglected.

A Dull, Dirty Appearance

If your siding looks faded, dingy, or noticeably darker than it used to, accumulated dirt and environmental grime may be the cause. A professional house wash can refresh the exterior and restore its clean appearance.

What We Look for During a House Wash

At Johnny Tsunami, our trained crews do more than clean the visible surface. We assess the exterior as we work, looking for buildup, wear, and areas that may need additional attention.
  • Mildew, Algae, and Moss Buildup
    We look for organic growth along siding, shaded areas, and other moisture-prone surfaces so it can be properly treated and removed.
  • Warped or Damaged Siding
    We pay attention to signs of cracking, swelling, loose materials, or other visible siding issues before beginning the wash.
  • Grime Around Vents and Windows
    Dirt and buildup often collect around windows, vents, trim, and other detailed areas. We make sure these commonly overlooked spots receive proper attention.
  • Rust Marks and Water Stains
    Rust streaks and water stains around gutters, fixtures, and exterior features can stand out against otherwise clean siding. We identify these areas and determine the appropriate cleaning approach.
