Charlottesville sits in a humid pocket of Central Virginia with heavy spring pollen and plenty of shade trees. That combination feeds algae, mildew, and a dull film on siding faster than drier climates. Most homes here look better with a professional wash every one to three years — not because you're doing something wrong, but because the climate works against curb appeal.
Soft wash vs pressure wash
For house siding, soft washing is usually the right method: low pressure plus cleaners that kill organic growth. High-pressure washing is better for concrete driveways and some hardscape. If a quote only talks about "blasting" the house, ask about soft wash — especially on vinyl, fiber cement, or painted wood.
Signs it's time
Book a wash when you notice:
- Green or black streaks on the north side
- Pollen film that rinsing with a hose won't lift
- Slippery mildew on steps or a deck
- Gutters overflowing because debris sat too long (clean those too)
Local timing tip
Late spring after the heaviest pollen drop, or early fall before leaves pack the gutters, are popular windows in Charlottesville and Albemarle. Wooded lots in Crozet, Earlysville, and Ivy often need the shorter end of the 1–3 year range.
