House Washing in St. Augustine, FL
A house wash is not a pressure wash. Siding, stucco and painted timber are cleaned with low pressure and a cleaning solution that kills the organic growth — the pressure only rinses.

What actually causes the staining
The black and green film on a north-facing wall in St. Johns County is almost never dirt. It is mildew, algae and lichen feeding on moisture that never fully leaves. We are humid nearly year round, we sit on the water, and salt air holds damp against a wall long after the rain stops.
Blasting that with high pressure removes the top layer and leaves the roots. It comes back within a season, and on vinyl or stucco you risk driving water behind the surface. A soft wash treats the growth chemically, then rinses.
Surfaces and how each is handled
- Vinyl siding — soft wash only. High pressure forces water behind the panels and into the wall cavity.
- Stucco and painted stucco — soft wash. Stucco is porous; pressure opens hairline cracks and can lift paint.
- Fibre cement (Hardie) — soft wash. Durable, but the factory finish is not improved by being scoured.
- Brick and block — soft wash, with slightly more rinse pressure where mortar is sound.
- Painted timber — the gentlest setting. Older coastal paint chalks, and aggressive washing takes the paint with the mildew.
Questions
Worth asking before you book
Will it damage my paint or siding?
Not when the method matches the surface. The pressure at the wall is lower than a garden hose on a jet setting — the cleaning is chemical, not mechanical. Damage happens when someone brings a 3,000 PSI wand to vinyl or chalking paint.
Do you need access to my water?
Yes, an outside spigot is the normal setup. If the property has no working outside tap, say so when you call so it can be planned for.
What about my plants?
Beds and foundation planting get pre-wet before any solution goes on the wall, and rinsed again after. That is standard practice, not an extra.
