Commercial Window Cleaning in Portland
Professional interior and exterior window cleaning for Portland businesses. Streak-free clarity for storefronts, offices, and multi-story buildings. Because first impressions start at the window.
Why Professional Window Cleaning Matters
Dirty windows aren't just unsightly—they're costly. For retail businesses, grimy windows signal neglect and drive customers away. For offices, they reduce natural light by up to 40%, affecting employee mood and productivity. And for property managers, neglected windows degrade faster, requiring expensive replacement.
Portland's wet climate makes this even more critical. Rain doesn't clean windows—it leaves mineral deposits, dirt streaks, and that distinctive Pacific Northwest green tinge from algae and moss. DIY cleaning often makes it worse, leaving streaks that become painfully obvious when the sun finally comes out.
🏢 Professional Image
Clean windows signal attention to detail and professionalism. Dirty windows make even well-maintained businesses look neglected.
☀️ Natural Light
Dirty windows block 30-40% of natural light. Clean windows reduce lighting costs and improve employee wellness.
🛡️ Window Longevity
Mineral deposits, hard water stains, and oxidation etch glass permanently if left untreated. Regular cleaning extends window life by years.
Our Streak-Free Window Cleaning Process
We don't spray and wipe. Professional window cleaning requires the right technique, tools, and solutions to deliver crystal-clear, streak-free results that last.
Pre-Cleaning Inspection
Identify problem areas: hard water stains, paint overspray, construction residue, oxidation, or damaged seals. Determine which windows need special treatment beyond standard cleaning.
Frame & Sill Cleaning
Brush or vacuum window tracks, sills, and frames to remove debris, dead bugs, and dirt buildup. This prevents contamination when cleaning glass.
Professional Scrubbing
Apply professional-grade cleaning solution with scrubbing pad or T-bar applicator. Work solution into all edges and corners. For heavily soiled windows, use specialized cleaners for hard water stains or construction debris.
Squeegee Technique
Professional squeegee work in overlapping strokes from top to bottom. The right technique, pressure, and blade angle are what separate amateur streaks from professional clarity. We wipe the blade after every stroke.
Detail Edging
Microfiber towels to detail all edges, corners, and any remaining water. This final step is what eliminates streaks and water spots that appear after drying.
Final Inspection
Quality check from multiple angles and lighting conditions. We fix any missed spots or streaks before leaving.

Portland Window Cleaning Challenges
Portland's climate isn't just wet—it's uniquely challenging for window maintenance. Here's what we deal with that national chains don't understand:
🌧️ 160+ Days of Rain (It's Not Just Water)
Portland rain contains dissolved minerals, volcanic ash particles (from Mt. St. Helens and beyond), and organic matter. When it dries on windows, it leaves behind mineral deposits that etch glass over time. Simple water doesn't fix this— you need the right cleaning solutions and technique.
🍃 Algae, Moss & Mildew Growth
That green tinge on north-facing windows and shaded areas? Algae. Portland's mild, wet climate is perfect for organic growth on glass surfaces. Left untreated, it becomes harder to remove and can permanently stain certain window types. We use anti-algae treatments to slow regrowth.
🌲 Tree Sap & Pollen
Portland's abundant trees (Douglas fir, big leaf maple) drip sap onto windows, especially in spring. Tree pollen in May-June creates a yellow film. Both require specific cleaning agents—standard solutions just smear them around.
🦆 Bird Droppings (Especially Pigeons)
Downtown Portland and Pearl District buildings deal with constant pigeon activity. Bird droppings aren't just unsightly—they're acidic and etch glass permanently if not cleaned quickly. We handle this weekly for some clients.
☁️ Persistent Cloud Cover = Hard Water Spotting
Portland's lack of consistent sun means water spots don't dry evenly. They leave behind concentrated mineral deposits in unpredictable patterns. Professional squeegee technique and proper detailing are essential to prevent this.
How Often Should You Clean Commercial Windows?
Cleaning frequency depends on your business type, location, and how your windows are exposed to Portland's elements:
