We’re Portland’s Residential Window Specialists — Not a Handyman Add-On Service
We clean windows. Not gutters as the main business with windows tacked on, not a 15-service janitorial company where glass is one line item. Every technician is trained specifically on glass, frame, and track work — squeegee technique, proper solution mixing, and edge detailing — because that specialization is what actually produces a streak-free result on Portland’s older, multi-pane housing stock.
Two home types dominate our Portland service calls:
- Older, multi-pane homes (pre-1930s inner neighborhoods): French panes, storm windows, and original wood frames — more surface area and more joints where grime and moss collect, and more care needed not to damage original glass or trim.
- Modern homes with larger single-pane windows: Faster to clean per window, but often taller and harder to access safely without proper ladder or water-fed pole equipment.
Each type needs a different approach on pricing, timing, and technique — that’s why we assess by home, not by a flat per-window rate alone.
Who we help:
- Homeowners who haven’t had windows professionally cleaned in over a year and are seeing spotting, film, or moss
- Time-poor households who know the job needs doing but don’t have a free Saturday and a ladder
- Owners of historic or multi-level homes uneasy about doing upper-story windows themselves
- Homeowners prepping for a home sale who need curb appeal and natural light maximized for listing photos
- Anyone tired of streaky results from spray-and-wipe glass cleaners
Why Portland Homes Need Window Cleaning More Often Than You’d Think
Portland’s climate makes window grime seasonal and cumulative, not a one-time mess.
- October–May (Rainy Season): Roughly 100+ days of measurable rainfall — but it’s light, repeated drizzle, not hard rinse-off rain. Each cycle redeposits a fresh film of dust and grit rather than washing it away.
- February–April (Pollen Season Ramp-Up): Waxy tree pollen clings to glass, worse on tree-lined streets like Alameda and Laurelhurst, leaving a yellow-green haze.
- Late Summer–Early Fall (Wildfire Ash Risk): Alkaline wildfire ash can damage glass porosity if left sitting on the surface — a newer, genuinely protective reason to clean before it settles in.
- Winter (Condensation Season): Cold, wet weather drives interior condensation on older single- and double-pane windows, promoting mold at the sash and stressing seals over time.
We’ve seen it firsthand: skipping a season doesn’t just mean dirtier glass — mineral spotting left too long etches permanently into the surface, and grime trapped at a seal accelerates the kind of wood rot and seal failure that turns a $150 cleaning into a $200–$500 per-window replacement.

Our Proven 6-Step Residential Window Cleaning Process
1. Quick Phone or Photo Quote (2–5 minutes)
Tell us your home’s approximate window count or send a few photos — we’ll give you a real price range before we schedule, not a vague “contact us.”
2. Frame & Track Pre-Clean
Before glass work starts, frames and tracks get wiped down with a gentle soap solution so loose dirt doesn’t drag onto the glass later.
3. Glass Agitation
A microfiber scrubber loaded with a dish-soap solution (the actual professional standard, not spray-and-wipe chemical cleaners) lifts film and lubricates the surface — this step alone is why professional results outperform DIY spray bottles.
4. Squeegee Detailing
A sharp, properly angled blade clears each pane in overlapping passes, always working toward the wet edge to prevent water lines — on larger windows, done with a continuous “fanning” motion for a streak-free finish edge to edge.
5. Edge & Sill Detailing
A lint-free microfiber towel dries the narrow strip along the frame the squeegee can’t reach, and sills get a final wipe-down.
6. Final Inspection & Optional Protective Sealant
Every window gets a second look before we call it done. An optional hydrophobic sealant is available to slow how fast Portland’s climate reloads grime over the following months.

The Homes Themselves: Why Portland’s Housing Stock Changes the Job
The climate section above explains when Portland windows get dirty. But how they need to be cleaned depends on the house itself — and Portland’s housing stock is unusually varied. A cleaner who treats every home the same is missing half the job.
Pre-1940 wood windows (Laurelhurst, Irvington, Alameda). These neighborhoods are full of original wood sashes. Old paint always fails first at the edges, and once bare wood is exposed it drinks in moisture. Cleaning these windows isn’t just about the glass — the frames need a gentler touch, and anyone who attacks a 1925 wood sash the same way they’d hit a vinyl slider is asking for paint damage.
Mid-century aluminum sliders (Montavilla, St. Johns). Aluminum frames oxidize into a chalky residue that streaks the glass every time it rains. And the tracks on these windows are often the worst part of the whole job — decades of grit packed into narrow channels that haven’t moved freely in years.
Newer vinyl and fiberglass (Pearl District condos, recent builds). Easier to clean, but the seals on budget vinyl units vary wildly in quality. A careful cleaner checks for early seal stress instead of just squeegeeing past it — catching a failing seal early is worth more than the cleaning itself.
The shade problem. Portland’s west-side slopes and north-facing windows can go weeks without direct sun in winter. Add the Douglas fir canopy — needles and sap raining down year-round, packing into tracks and holding moisture against sills — and shaded windows stay damp enough for algae to take hold on the glass itself, not just the frames.
The takeaway: the window type, the exposure, and the tree cover change what the job actually requires. That’s why the first thing we do on a new home is look at the windows before we touch them — not after.
The Neglect Timeline: What Happens When Windows Go Too Long
Skipping a season doesn’t just mean dirtier glass. Here’s what actually happens inside that grime, stage by stage:
Months 1–3: the film. Dust and pollen settle into a light haze. Purely cosmetic — a careful DIY wipe still handles it fine at this point.
Months 4–8: the bond. Portland’s waxy spring pollen doesn’t rinse off in the rain; it bonds to the glass. Sprinkler overspray starts leaving mineral spots. Tracks collect enough grit that sashes begin to drag. A simple wipe won’t cut it anymore.
Year 1–2: the etching begins. Hard-water spots left through a full rain cycle start etching into the glass surface — and etching is permanent. Screens clogged with pollen and fir needles choke off airflow and light. This is the point where the job stops being “cleaning” and starts needing professional treatment.
Year 2 and beyond: the repair zone. Moisture trapped at the seals stresses them; wood sills begin to soften. What would have been routine maintenance becomes restoration work — or replacement.
The pattern never changes: the longer you wait, the more the job shifts from cleaning to repairing. Twice-a-year service isn’t upselling — it’s the cheapest way to keep your windows in the “cleaning” category.
More Residential Questions, Answered
Is professional window cleaning worth it, or should I just do it myself?
For ground-floor, easily reached windows, DIY is perfectly fine. A professional earns their keep in three situations: second-story and hard-to-reach glass (ladder safety is no joke), the detail work most homeowners skip (tracks, sills, screens), and spotting early problems like seal failure or etching before they turn expensive. If your home has any of those three, it’s worth it.
Why do window cleaning quotes vary so much?
Because “window cleaning” means different things to different companies. A low quote often means glass-only — no screens, no tracks, no sills. A higher quote usually covers the full detail job plus trained, insured technicians. When comparing quotes, ask exactly what’s included: the cheapest glass-only wipe and a full interior/exterior detail are not the same service.
How long will my windows stay clean after a professional cleaning?
In Portland, exterior glass typically holds 4–6 months — the rain cycle and pollen season set the pace. Interior glass stays clean much longer, often a year or more. Homes under heavy fir canopy or near busy roads will see the exterior haze return sooner.
Do I need to be home during the cleaning?
Not necessarily. Exterior-only cleanings don’t require you to be home at all, as long as we can reach outdoor spigots and gates are unlocked. For interior work, someone needs to let us in — but you don’t need to follow us from room to room.
Do I need to move furniture or take down blinds first?
Just clear the sills — move plants, frames, and small items off the window sills before we arrive. We handle blinds and curtains carefully ourselves; you don’t need to take anything down. If a heavy piece of furniture blocks a window, we’ll work around it.
What if my window screens are stuck or painted shut?
Extremely common in Portland’s older homes. We’ll try to remove screens gently, but we will not force a painted-shut screen and risk cracking the frame — we’ll clean it in place instead and tell you what we found. Forcing it is how frames get broken.
What happens if it rains the day after my cleaning?
Nothing bad. Professional cleaning already wets the glass with soap solution and squeegees it dry — rain doesn’t undo that. Here’s the difference that matters: rain hitting clean glass sheets off; rain hitting dirty glass leaves spots. That’s the whole story.
