Why mid-October is the most important window cleaning of the year.
Posted October 19, 2026 · By Barrett Teeney
Mid-October has the best conditions of the year for window cleaning: cool but not cold, dry, low pollen, no bugs. The clean lasts five months because winter air doesn't carry dust.
Fall cottonwood fluff is more annoying than spring pollen because it sticks to everything fibrous — screens, weatherstripping, gutter inserts. Brush screens dry first; wet seed-fluff turns to glue.
Debris from gutters splashes onto windows on the next rain. If you clean gutters in fall, do it before windows.
Interior cleans look great in low-angle winter sun and through holiday lights. Mid-November booking is the move.
Seasonal residents leaving for the season: clean windows last after everything else. Final lockup, departure-ready glass means you walk into a fresh house in spring.
We book up two to three weeks out by mid-October. Spring is the same — call early.
