Awning Washing and Cleaning

Awning Washing and Cleaning in Seattle

SkySWC provides professional awning washing and cleaning for commercial and residential properties throughout Seattle. Awnings take the full force of Seattle's year-round weather — rain, pollution deposits, bird droppings, mold, and algae staining accumulate quickly on both fabric and metal awning surfaces.
A dirty awning is often the first thing customers see before entering your business. Regular professional cleaning maintains your storefront's appearance, extends awning lifespan, and protects the investment you have made in commercial signage and exterior branding.

Awning Materials We Clean

Fabric Awnings

Canvas, Sunbrella, acrylic, and vinyl-coated fabric awnings require low-pressure washing with cleaning solutions specifically formulated for fabric — avoiding high pressure that damages fibers, bleaches color, or compromises water-repellent coatings. We use soft washing techniques that remove biological growth, staining, and environmental deposits while preserving fabric integrity and water resistance.

Metal and Aluminum Awnings

Metal awnings accumulate oxidation, pollution deposits, bird droppings, and biological staining that standard cleaning cannot address. We clean aluminum, steel, and copper awning structures using appropriate techniques for the metal type, removing oxidation and staining without damaging protective coatings or painted finishes.

Polycarbonate and Acrylic Panels

Clear and translucent awning panels accumulate algae, mineral deposits, and haze that block light transmission and diminish appearance. We clean polycarbonate and acrylic panels using solutions that remove staining without scratching or hazing the material surface.

What Seattle Weather Does to Awnings

Seattle's combination of persistent rain, atmospheric pollution from vehicle traffic and industry, nearby saltwater environment, and mild temperatures that support year-round biological growth creates uniquely challenging conditions for awning maintenance:

  • Mold and mildew — constant moisture creates ideal conditions for biological growth on any porous awning surface
  • Green algae streaking — algae spores transported by rain and wind colonize awning surfaces rapidly in Seattle's climate
  • Black streaking — Gloeocapsa Magma bacterial staining is visible on light-colored awnings throughout the region
  • Tannin staining — overhanging trees deposit tannin-rich water that causes permanent-appearing brown staining on fabric surfaces
  • Salt haze — marine air affects properties within several miles of Puget Sound, depositing a haze on all exterior surfaces

How Often Should Awnings Be Cleaned in Seattle?

Most Seattle commercial awnings benefit from professional cleaning at least twice per year — once in spring following the rainy season and once in fall before it begins. Restaurant and hospitality awnings with grease and cooking deposits may require quarterly cleaning. Light-colored fabric awnings in high-traffic areas often show soiling quickly and benefit from more frequent service.
Regular scheduled cleaning is significantly more effective and less costly than infrequent deep cleaning — biological growth and staining that is addressed before it becomes established is far easier to remove.

FAQ

Can you clean awnings without removing them from the building?

In most cases, yes. We clean awnings in place using appropriate equipment and techniques for the awning type and soiling level. Removal is generally only necessary for severe restoration situations or awnings that require repair before cleaning can proceed effectively.

Will awning cleaning restore faded colors?

Professional cleaning restores the appearance of fabric awnings by removing the biological growth and dirt overlay that dulls color. Genuinely faded or UV-bleached fabric cannot be restored by cleaning — color degradation from UV exposure is permanent. We can assess your awning's condition and provide an honest evaluation of what cleaning can achieve.

Do you clean awnings on multi-story buildings?

Yes. SkySWC's aerial lift and rope access capability allows us to clean awnings at any height on commercial buildings. We are fully insured for high-access work and can coordinate with your property management team for access and scheduling.
