Key Cost Factors for Window Cleaning EstimatesNumber of Windows & Panes: Most cleaners bill per pane, not per sash. For instance, a double-hung “window” has two sashes with two panes each—so that’s four panes to clean.Window Size & Style:A typical 24″×36″ pane might run $3–$8 each.Larger picture or sliding panes often cost $15–$25 apiece (more solution, more time).Specialty shapes like arches or transoms might be $20–$40 per pane.Height & Accessibility:Ground-floor work: base rate.One or two stories up: add $5–$10 per window for ladder time.Three stories-plus: professionals may need rope-access or lifts—$20–$50 extra per pane.Interior vs. Exterior:Exterior-only typically $3–$8 per pane.Adding interior glass and frame wipe can tack on 25–50% more, since it requires moving furniture and more careful handling.Window Condition:Light dust or pollen is charged at the standard rate.Stubborn stains (hard water, paint overspray, bird droppings) often cost an extra $5–$15 per pane for special treatment.Cleaning Frequency/Contract:One-off visits: highest per-visit fee.Quarterly or biannual: about 10–20% off each trip.Monthly or weekly: you might land a 20–30% discount.Geography:City dwellers often see 10–25% higher rates than rural customers because labor and insurance cost more in urban areas.Add-Ons:Screens: +$1–$3 each.Track & sill vacuuming: +$2–$5 per window.Tough hard-water stain removal (etching): +$10–$20 per pane.Side-by-Side: Typical Pricing Models Service TypePrice (per pane)What’s IncludedNotesExterior Only$3–$8Glass, basic frame wipeGood for regularly maintained homesInterior + Exterior$5–$12Both sides of glass, frame & track wipeRequires moving furniture insideHigh-Rise (3+ stories)$25–$50Exterior via ropes or liftsLicensed pros, higher risk workSpecialty Shapes (arches, etc.)$20–$40Custom detailing, careful handworkBay, bow, arched—more time-consumingHeavy-Soiling / Stain Removal$10–$20De-scaling solutions, extra scrubbingMay need more than one passQuarterly Contract (Exterior)10–20% offScheduled exterior cleaningLocked-in savings for regular serviceScreen & Track Add-On$1–$5Screen snatch, clean + track vacuumingOften bundled to save on extra tripsDIY Window Cleaning 101
If you want to tackle it yourself, gather:Cleaning Solution: Mixing one part white vinegar with two parts distilled water works great. Or grab a pro-grade window cleaner.Squeegee (10″–14″): Stainless-steel or rubber blade—choose a size that roughly matches your window width.Microfiber Cloths & Soft Scrubber: For a streak-free finish and gentle frame cleaning.Bucket & (Optional) Pure-Water Hose Attachment: Deionized or filtered water prevents mineral spots if you have calcium-rich tap water.Extension Pole & Safe Ladder: For upper-level windows, use a sturdy A-frame ladder with non-skid feet and consider an extendable pole so you don’t overreach.Step-by-StepDust Off: Wipe or brush away loose dirt, cobwebs, and bugs from frames and glass.Apply Cleaner: Mist on your vinegar solution or professional cleaner top-to-bottom. For really grimy panes, let it soak for 20–30 seconds.Scrub Gently: Use a soft scrubber in a circular motion to break up spots or pollen.Squeegee in Strokes: Starting at the top corner, pull straight across or down in one smooth stroke. After each pass, wipe the blade with a clean rag—overlap each stroke by 1–2 inches to avoid streak gaps.Catch the Drips: Keep a microfiber cloth or small towel on the sill to catch drips—wipe the sill afterwards so it doesn’t drip onto the floor.Frame & Track: Wipe down frames, sills, and tracks with a damp microfiber cloth and mild detergent. Dry everything thoroughly to avoid mold or rust.Final Check: Step back, scan for streaks or missed spots, and buff any blemishes with a dry cloth.DIY vs. Professional: Which Makes Sense?

For most homes, spring and fall (twice a year) hits the sweet spot. Dusty or coastal regions may need quarterly cleanings to keep salt or pollen from building up.Can I use vinegar on all window types? Standard glass is fine with vinegar. But if you have tinted or Low-E windows, check the manufacturer’s instructions—some coatings need a neutral-pH cleaner.Do I need special gear for second-story windows? A stable, approved ladder is a start. Many DIYers use water-fed extension poles, but if your home is three stories or more, hiring a pro with rope-access or lift equipment is safest.Why do prices vary so much by city? Labor, insurance, and overhead costs are higher in big urban centers (New York, Toronto, etc.), so you’ll pay 10–20% more than rural areas. Also, spring/fall call volumes spike rates.Is hiring a pro worth it? If you have many windows, high windows you can’t easily reach, or want guaranteed streak-free results, professionals often end up saving you time, frustration, and potential ladder-related injuries.Authoritative Links to ExploreInternational Window Cleaning Association (IWCA): Best practices, safety guidelines, and pro tips.
