Mid-March through May is the heaviest booking pressure of the year. Pollen wave drives the residential surge. April through early May is the peak production rate for Indianapolis residential.
June through August is the production window. Mild July-August humidity squeeze. Storm activity occasional but does not generally shut down work.
September through early November is the cleanest production stretch. Agricultural-drift residue from harvest activity peaks late September through October.
Late November through February is mostly interior-only for residential and light-commercial work. Northwest Indiana sees more lake-effect-snow disruption than central Indiana. Commercial interior work is the off-season backbone.
Wet-only handling. Peak mid-April. Pollen lifts cleanly with water plus light alkaline soap; do not scrape.
