How Often Should You Pressure Wash Your Driveway?

The short answer: most driveways need a full wash every 12–24 months. The long answer depends on four things — tree cover, traffic, drainage and whether the concrete was ever sealed. Here's exactly how we size it up on a quote visit.

The 2-minute driveway test

Walk to the middle of your driveway and look for these three signs. If you see two or more, you're overdue: dark tire-tracking lines that don't fade when wet, green or black tint in the textured areas and expansion joints, and oil or rust spots wider than a coin. Any one of them means a wash will make a dramatic difference.

What speeds up the grime

Shade is the biggest accelerator — north-facing drives under oaks or pines can moss over in a single damp season. Next comes traffic: a two-car household grinds in roughly twice the rubber of a single car. Poor drainage leaves standing water that feeds algae, and unsealed concrete absorbs oil like a sponge, turning small drips into permanent-looking shadows.

Our scheduling rule of thumb

Sunny, sealed, light-traffic driveway: every 24 months. Average suburban driveway: every 12–18 months. Shaded, unsealed or heavy-traffic: every 12 months, paired with a penetrating sealer every 3–5 years. Sealing after a deep clean is the closest thing to a pause button — oil beads on top instead of soaking in.

Between washes: the 10-minute habit

Blow leaves off monthly so tannins don't leach brown stains into the slab. Hose down fresh oil drips within a day or two — cat litter ground into the spot overnight absorbs most of it. And keep sprinklers aimed off the concrete; iron-rich well water paints rust arcs that are far harder to remove than to prevent.
