Exterior Window Cleaning
Serving Tigard, OR
48-Hour Streak-Free Guarantee
Streaks after service? We come back and re-clean at no cost.
Portland's wet climate leaves mineral deposits and a gray film on exterior glass over time. We dissolve it with the right chemistry — not just water.
We handle multi-story homes safely with proper equipment. You stay on the ground while we take care of every pane.
Spring in the Portland metro is rough on windows. We clear every pane and inspect screens that trap pollen and push it inside.
Mineral buildup permanently etches glass if left too long. Seasonal exterior cleaning protects your windows for years.
Tigard sits between Portland and Lake Oswego with a mix of established and newer residential neighborhoods. Mature landscaping and proximity to the Tualatin Valley means heavier pollen in spring and consistent grime buildup through the rainy season.
Tigard's mature neighborhoods and Tualatin Valley position mean consistent pollen, moss, and grime buildup. We're one of the most active window washing services in the area.
"Quick to respond, fair price, and the windows look amazing. They cleaned the screens too — I wasn't expecting that. Will definitely use Cascade again."
Exterior glass often has heavier buildup — mineral deposits, oxidation, tree sap. It requires stronger solutions, more time, and sometimes ladder or pole work.
We use professional extension poles and proper ladder equipment. All work is fully insured and done safely regardless of height.
Rain by itself won't re-dirty clean glass. Minerals in standing water cause the film — once properly cleaned, light rain simply runs off clean glass.
Yes — we cover all of Tigard including Bull Mountain, Metzger, Summerfield, King City, and the Washington Square corridor.
Absolutely. Fall is the ideal time to pressure wash before heavy winter rain sets in. We clear moss, algae, and stains so your driveway stays cleaner through wet months.
