June through August is the production window. Long dry stretches, no canopy washoff, dust the only real factor. East of the Cascades, this is also when the irrigation-overspray etching season starts on Bend stock.
September through October is the smoke-watch season. Plan for one or two weeks of smoke residue work in any given year. October is also the last good month for high-pole work before the rain returns.
November through February is interior-only and emergency exterior work on the west side. Indoor commercial accounts (offices, hotels, retail) move to monthly or bi-monthly schedules. East of the Cascades, snow on the ground from December through February means residential exterior is mostly impossible.
