Hillsboro homeowners trust Cascade for clean results, on-time service, and a streak-free guarantee that means what it says.
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.
We assess every exterior window — height, accessibility, stain level, hard water deposits. You get an exact scope and price before we touch anything.
Problem areas get pre-treated. Then we wash and squeegee every pane using professional technique — top to bottom, edge to edge, no misses.
Every exterior frame and sill is wiped. We walk the job (or send you photos) before we leave. If anything's off, we fix it on the spot.
Hillsboro is Washington County's largest city with neighborhoods ranging from older downtown homes to newer tech-corridor suburbs. Agricultural surroundings produce some of the highest seasonal pollen and dust levels in the entire metro area.

"I'd been looking for a reliable window cleaner in Hillsboro for years. Cascade finally delivered. On time, great work, fair price."
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 — all of Hillsboro including Tanasbourne, Orenco, AmberGlen, South Hillsboro, Quatama, and the downtown core.
Hillsboro's proximity to agricultural land means higher seasonal pollen and dust than central Portland. Homes near fields may need quarterly cleaning.
