Pressure Washing in St. Louis, MO: Siding, Decks, Drives Without Damage

Pressure washing in St. Louis, MO is the fastest way to refresh a tired exterior — green algae on the north side of a house, mildew on a shaded deck, oil stains on a driveway. The catch is that the wrong pressure on the wrong surface causes the damage you were trying to remove. Vinyl, wood, concrete, and stucco each need a different approach. Here's how we wash without harming the surface.

What we pressure wash

• Vinyl and aluminum siding (algae and grime)
• Wood decks and fences (mildew and gray weathering)
• Concrete driveways, walks, and patios (oil and stains)
• Fences and railings
• Stucco and masonry (low pressure only)

The right pressure per surface

Vinyl siding: medium pressure and a house-wash solution that kills the algae so it doesn't return in a month. Wood decks: low pressure and a wood-safe cleaner, because high pressure tears the soft spring growth and leaves splinters. Concrete: high pressure with a surface cleaner for even lines. Stucco and masonry: very low pressure, because high pressure drives water behind the surface and causes damage.

Soft wash vs. pressure wash

For siding, we often soft wash — apply a cleaning solution, let it work, and rinse at low pressure. It cleans better, lasts longer, and doesn't risk driving water under the siding the way high pressure can. We use true pressure washing where the surface can take it (concrete, some decks) and soft wash where it can't.

Deck cleaning and prep

A deck wash is usually step one of a refresh. We clean, let it dry, and the deck is ready for a new stain or sealer — or it's ready to leave bare if the wood is sound. We handle the fence and deck repair and staining too, so the whole refresh is one visit.
