How Often Should You Pressure Wash a St. Louis-Area Driveway?

For a typical suburban driveway in places like O’Fallon or Ballwin, plan on cleaning about once a year or every other year. You’ll know it’s time when tire film, leaf tannins, or mildew make the concrete look permanently wet or blotchy.

• Trees overhang the drive (tannins and organic slime)
• Sprinklers leave white mineral spots
• Multiple daily vehicles track oil and rubber
• You’re prepping to seal the concrete

Concrete cleaning removes the staining you see. Sealing adds a protective layer that helps resist absorption of spills and makes the next clean easier. Many homeowners bundle both after a deep clean in spring or fall.

If the siding is due for house washing too, combining visits saves mobilization time and usually looks more cohesive from the curb — clean walls above a still-stained drive is a common “halfway done” look we help people avoid.
