Window Washing
Interior and exterior window cleaning using pure water technology — streak-free results that last longer, with screen and track detailing included on every visit.
Professional Window Cleaning That Goes Beyond the Glass
Living in Portland means your windows are fighting a constant battle. Rain deposits mineral spots, spring pollen coats every surface in a yellow-green film, and road dust from nearby construction settles into a haze you barely notice — until your windows are cleaned and the difference is startling. Our technicians use deionized pure water systems that leave zero residue behind, which means your glass stays cleaner between visits compared to traditional soap-and-squeegee methods. We clean interior and exterior panes, pull and wash every screen, vacuum out window tracks, and detail sills. For upper-story windows, our water-fed poles reach up to three stories from the ground — no ladders leaning against your siding, no boots on your roof.
What Makes Our Window Washing Different
Technology, attention to detail, and a process designed for the Pacific Northwest climate.
Pure Water System
Deionized water contains zero dissolved minerals. It dries spotless without wiping, and windows resist new deposits longer than soap-cleaned glass.
Water-Fed Poles
Carbon fiber poles deliver pure water up to three stories high. No ladders against your home, no risk to your siding or landscaping.
Screen & Track Cleaning
Every screen is removed, scrubbed, and rinsed. Tracks are vacuumed and wiped clean so windows slide smoothly and seal properly.
Seal Failure Detection
We spot the early signs of double-pane seal failure — fogging between panes, moisture trails — and alert you before condensation causes permanent damage.
Interior & Exterior
Both sides of every accessible window are cleaned. Interior work is done with drop cloths and careful attention to your furnishings and floors.
Streak-Free Guarantee
If you find a streak or spot within 48 hours of our visit, we return and re-clean the affected windows at no additional cost.
How Our Window Cleaning Works
A systematic approach that covers glass, screens, tracks, and sills on every visit.
Walk-Through & Assessment
We count every window, note hard water staining, check for seal failures, and identify any areas requiring special attention before we begin.
Screen Removal & Cleaning
Screens are carefully removed, scrubbed with soft brushes, rinsed, and set aside to dry. This step alone dramatically improves the view through your windows.
Glass Cleaning — Inside & Out
Exterior panes are cleaned with pure water via poles or squeegees. Interior glass is hand-cleaned with microfiber and professional-grade solution. Tracks and sills are detailed.
Final Inspection & Screen Reinstall
Every pane is checked from multiple angles for streaks or spots. Screens are reinstalled, and we do a final walk-through with you to confirm satisfaction.
Why Portland Windows Get Dirty So Fast
Portland’s climate creates a unique cycle that keeps your windows perpetually coated. From October through June, rain deposits dissolved minerals onto the glass surface. As water evaporates, those minerals — primarily calcium and silica from our naturally hard water — are left behind as white spots and cloudy film. In spring, cottonwood and alder pollen blankets the city, sticking to damp glass and creating a gritty yellow-green layer. Through summer, construction dust from Portland’s ongoing development settles across exterior surfaces, and homes near I-5, I-84, or Powell Boulevard collect a fine road film that dulls the glass further.
The result is a compounding problem. Each layer bonds to the one beneath it, and within a few months, windows that were crystal clear become noticeably hazy. Most homeowners adapt to the gradual change without realizing how much natural light they are losing. After a professional cleaning, the difference in brightness inside the home is immediately obvious — rooms feel larger, paint colors look richer, and you actually see the view you are paying your mortgage for.
How Pure Water Technology Works
Traditional window cleaning relies on soapy water and a squeegee. The squeegee removes most of the water, but soap residue remains on the glass in a thin film. That film is slightly sticky, which means dirt and pollen adhere to it faster than they would to bare glass. Within a couple of weeks, windows cleaned this way already look dull. Our pure water system takes a fundamentally different approach:
- Multi-stage filtration — Tap water passes through sediment filters, carbon filters, and a deionization resin that strips out every dissolved mineral.
- Zero TDS output — The resulting water has zero total dissolved solids, meaning nothing is left behind when it evaporates on the glass.
- No soap needed — Pure water is an aggressive solvent on its own. It actively pulls dirt off the glass surface without chemical assistance.
- Longer-lasting clean — With no sticky residue, glass stays cleaner between visits. Most clients notice a measurable difference compared to their previous cleaning service.
- Safe for all frames — No soap means no chemical contact with wood, vinyl, or aluminum window frames. Pure water rinses clean and dries without a trace.
Clean Windows Improve More Than Just the View
Beyond aesthetics, there are practical reasons to keep your windows clean. Mineral deposits and grime reduce the amount of sunlight that passes through the glass, which means your home relies more on artificial lighting during the already-short daylight hours of a Portland winter. Clean glass transmits noticeably more natural light, which can reduce energy costs and improve mood during the gray months. Additionally, regular cleaning extends the lifespan of your windows by preventing mineral etching — permanent damage that occurs when hard water deposits are left on glass for extended periods. Etched glass cannot be restored; it must be replaced. Professional cleaning two to three times a year prevents etching and keeps your windows in top condition. Finally, clean windows contribute directly to curb appeal and home value, something worth considering in Portland’s active real estate market.
Window Washing FAQ
Answers to the questions Portland homeowners ask most about professional window cleaning.
How often should I have my windows professionally cleaned in Portland?
For most Portland homes, two to three times per year delivers the best balance between cost and clarity. We suggest scheduling after pollen season ends in late spring, once in late summer before fall rains begin, and optionally in early winter to remove accumulated mineral deposits from autumn storms.
Do you clean both the inside and outside of every window?
Yes. Our standard service covers both sides of every accessible window. Interior cleaning is done with drop cloths to protect your flooring and furniture. If you only need exterior cleaning — for example, between full-service visits — we offer that as a standalone option at a reduced rate.
What exactly is pure water cleaning?
Pure water cleaning uses water that has been filtered through a deionization system to remove all dissolved minerals. Because the water contains nothing but H2O, it evaporates without leaving spots or residue. It cleans more effectively than soap and keeps windows cleaner longer since there is no sticky film for dirt to adhere to.
Can you reach the windows on my upper floors without ladders?
In most cases, yes. Our carbon fiber water-fed poles extend to reach windows up to three stories from ground level. This eliminates the need for ladders, which means no risk of damage to your siding or landscaping and faster completion times. For certain configurations, we may use ladders, but ground-level cleaning is our default approach.
Are screens and tracks included in the service?
Every full-service window cleaning includes screen removal, hand scrubbing, and rinsing, plus track vacuuming and wipe-down. Dirty tracks hold moisture that can damage window frames over time, and clogged screens block airflow and filter out natural light. Cleaning them is essential, not an upsell.
Can you remove hard water stains from my windows?
Mild mineral deposits are removed during our standard cleaning process. Heavy buildup — the kind that feels rough when you run a finger across the glass — may require a specialized mineral removal treatment using fine polishing compounds. We assess the severity during our walk-through and quote accordingly if extra treatment is needed.
