The seasonal rhythm in Salem runs on the broader Oregon pattern — water and weather behave at the state level even when the housing stock varies by city.
March through May is the recovery wash season — the moss and algae buildup from the wet winter needs treatment, and most homeowner calls cluster here. Schedule moss-priority work for April once the worst of the atmospheric-river season has eased.
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.
The defining west-side Oregon substrate problem. North-facing windows under heavy canopy build a green-black film of mixed photosynthetic organisms that needs different chemistry than a normal wash. Sodium percarbonate or a quaternary ammonium prerinse, dwell five to ten minutes, then squeegee. Bleach is the wrong tool — it strips, but it lifts paint and stresses gasket rubber.
Anywhere with mature conifer canopy. The needle drop is mechanical and easy. The sap is a solvent-ladder problem — start with citrus, escalate only if needed.
