Exterior Window Cleaning With a Streak-Free, Spot-Free Finish in Northern Virginia
Pollen film, hard-water spots, and screen grime steal more daylight than you think. Our pure-water pole system cleans exterior glass, frames, and screens to a spot-free finish — no ladders against your siding, no streaks at 4pm.
The Short Answer
Most Northern Virginia exterior window cleanings run $8–$15 per window — screens, sills, and tracks included, not extra. Pure-water (deionized) technology scrubs the glass and rinses to a spot-free dry with no detergent haze, and second or third stories are reached safely from the ground by water-fed pole. Written quote within 24–48 hours of a free walkthrough.
Windows pair naturally with house washing — the soft wash cleans the siding, the pure-water pass finishes the glass, and the whole face of the house is done in one visit at a bundled rate. Spring-after-pollen is the single best slot of the year.
What's Included
Every Job, Done the Right Way
Our window cleaning service covers everything the job actually needs — matched to your surfaces, never one-size-fits-all.
- Pure-water wash — deionized water dries spot-free — no squeegee marks, no haze.
- Frames & sills wiped — the full window, not just the glass.
- Screens washed — removed, cleaned, dried, and reinstalled.
- Tracks brushed & vacuumed — the grime channel most cleaners skip.
- Hard-water treatment — mineral-removal chemistry where sprinklers have etched spots.
- Ground-based reach — second and third stories via water-fed pole — no ladders on siding.
- Skylights & transoms — cleaned where pole-reachable.
- Storm & specialty glass — technique adjusted for older and delicate windows.
Timeline: a typical 25-window home takes about two hours. Best seasons: spring after pollen and the pre-holiday fall window.
Why Pure Water Beats a Squeegee
Water filtered to near-zero dissolved solids scrubs the glass through a soft-bristle pole brush, then rinses clean and dries without spotting — because there are no minerals left to dry onto the glass. No detergent film for dust to stick to, no ladder feet against your siding, and no streaks appearing when the afternoon sun hits.
What drives your price: window count and size (standard, bay, and palladian price differently), height and access, condition (first-time cleans with hard-water spotting take restoration passes), and screens — which we include rather than upsell. A typical 25-window colonial runs $200–$375 and takes about two hours.

Local Knowledge
What Northern Virginia Windows Actually Deal With
- Pollen film builds by the daySpring oak and pine pollen coats glass and screens in a yellow-green haze that cuts daylight noticeably before most owners realize it.
- Sprinkler overspray etches glassIrrigation water carries minerals that dry onto lower windows daily — left long enough, the spots etch and become permanent.
- Screens re-contaminate clean glassDirty screens wash their grime onto the glass with the first rain — which is why we always clean both.
- Humidity feeds frame mildewShaded sills and frames grow mildew film in NoVA summers; wiping frames is part of the job, not an extra.
- Storm windows trap hazeOlder homes across Arlington, Alexandria, and Falls Church often carry storm panes that fog with trapped film between the two glass surfaces — careful two-surface cleaning restores clarity without disturbing older frames.
- Spring and pre-holiday book fastestPost-pollen spring and the pre-Thanksgiving window are the two rushes — schedule ahead for those slots.

Questions
Window Cleaning — Common Questions
How much does exterior window cleaning cost in Northern Virginia?
Most homes land at $8–$15 per exterior window including screens and sills — a typical 25-window colonial runs $200–$375. Bundling with house washing saves on both. Quotes are written and line-item. Palladians, transoms, and true divided-light windows quote a touch higher for the detail time — the walkthrough counts every pane so the quote is exact.
What is pure-water window cleaning?
Water filtered to near-zero dissolved solids scrubs the glass via a soft-bristle pole brush, then rinses clean and dries without spots — no squeegee marks, no detergent film, and no ladders leaned against your siding. Because nothing dries onto the glass, results hold visibly longer than squeegee work — typically months of clarity even through pollen season’s tail.
Do you clean window screens too?
Yes — screens come off, get washed and dried, and go back on. Dirty screens re-contaminate clean glass with the first rain, so cleaning glass without screens is a waste of your money. Screen frames get wiped too, so the aluminum doesn’t shadow the fresh glass.
How often should exterior windows be cleaned?
Twice a year keeps Northern Virginia pollen and rain spotting in check — spring after pollen season and fall before the holidays are the most popular slots. Annual cleaning is the practical minimum. Homes that skip a year notice it most in the kitchen and family-room glass, where interior humidity meets exterior film.
Can you remove hard-water stains from glass?
Usually yes, with dedicated mineral-removal treatment. Long-etched stains from years of sprinkler overspray can become permanent, which we will tell you honestly at the walkthrough. Treating sprinkler-side windows early each season is the cheapest way to keep spotting from ever reaching the etching stage.
Do you clean interior windows too?
Our specialty is exterior glass, which takes the weather beating from pollen, rain spotting, and sprinkler overspray. For interiors we will happily point you to trusted partners — or clean accessible interior glass by arrangement on larger jobs. For larger jobs we sequence with house washing so detergent overspray never lands on finished glass.
Is window cleaning safe for older or specialty windows?
Yes — pure-water poles apply less stress than ladder-and-squeegee work, and we adjust technique for storm windows, leaded glass, and historic frames. Historic and leaded glass gets hand attention at reduced pressure — the pole system throttles down further than any ladder squeegee can.
