Pine pollen wave March-April is heavy in the Atlanta-metro suburbs; presoak rinse standard during the window.
The seasonal rhythm in Marietta runs on the broader Georgia pattern — water and weather behave at the state level even when the housing stock varies by city.
Late March through May is the pollen war. Schedule pollen-priority washes for late April once the worst of the pine wave has passed. Earlier than that and you are washing the same windows twice. The first thunderstorm of April usually triggers homeowner panic calls — that is your tell that the season has started.
June through August is the heat-load season. Start routes at 6 AM, finish by 1 PM. Afternoon thunderstorms make the second half of the day a coin-flip. Squeegee rubber wears faster in the heat — swap blades twice as often as you would in spring.
October and November are the best window-cleaning months in Georgia. Pollen is gone, humidity drops, dew is heavy but burns off by 9. This is when the property managers want their commercial accounts done.
December through February is residential touch-up season. The pollen film does not return until late March, so any wash done in this window holds. Hard freezes are rare enough that scheduling is mostly weather-dependent rather than calendar-dependent.
Yellow film coats south- and west-facing windows across the metro. Functionally a thin organic coating, not a deposit — handle wet, never scrape dry. A single normal wash plus a strip-and-go rinse handles it on most stock. Heavy applications may need two passes.
Lower-sash problem on any house with exposed red clay within ten feet of the foundation. Sets within a week if not addressed. Acid-soluble — vinegar 1:1 with water handles fresh stains, citric or oxalic for set stains.
