Mid-March through May is the ice-dam-residue and spring-pollen window. Heaviest call volume of the year by a significant margin. May surge driven additionally by opening-the-cabin work in lake country. Booking pressure runs two to three weeks deep within a week or two of the first real thaw.
June through August is the production window. Lake-fly hatches affect lakefront work for several weeks. Storm activity occasionally disrupts schedules but does not generally shut down the work the way the winter does.
September through early November is the leaf-and-debris season but otherwise a clean production window. First hard frost typically ends the residential exterior season in late October or early November.
Late November through March is interior-only for residential and most light-commercial work. Indoor commercial accounts continue on regular schedules; commercial interior work is the backbone of off-season revenue. Maybe four to six usable exterior cleaning days in the whole stretch; some years none.
Six-to-seven-month exterior weather without intervention on lakefront cabin stock produces moss, algae, and lichen layers on north-facing exposures under heavy canopy. Sodium percarbonate prerinse with longer dwell. Quaternary ammonium pre-treatment on the heaviest cases.
