The best time to wash a house in Louisville is late spring, after tree pollen fades in May, with early fall as the runner up. The reasoning is pure Louisville, and it comes down to three local forces that set the washing calendar here.
Louisville regularly ranks among the worst allergy cities in America, and the tree pollen season that causes it runs from February into early June with a peak in March and April. Oak, maple, hickory, and birch coat every outdoor surface in that yellow green film. Wash a house at the peak and the film starts settling back the next morning. Wash in late May or June and the house stays clean into summer. If you only wash once a year, that window is the one to take.
The first Saturday in May fills thousands of Louisville patios and porches with guests, and the six weeks before it are the busiest stretch of the year for every washing crew in the metro. If the house needs to look right for Derby company, book by late March. The homeowners who call in April hear the same thing everywhere, and it is not what they want to hear.
Washing works best when daytime temperatures hold between 40 and 75 degrees. Below 40, cleaning solutions slow down and surfaces can ice. Well above 75 in direct sun, solution flash dries on siding and streaks. That makes April through June and September through October the sweet spots, though plenty of Louisville winter days clear the bar just fine.
Louisville sits in a river basin that traps humidity, and that dampness feeds the algae that greens up shaded siding. In this climate a wash is not a once a decade event. Homes under heavy tree cover in the Highlands or Anchorage do best with a spring wash and a fall touch up, and open sunny subdivisions can often stretch to a single annual visit.
