Why driveways in St Johns County get so dirty — and stay that way.
Northeast Florida's combination of red clay soil, heavy oak canopy, seasonal pollen, high humidity, and summer rain makes driveways some of the fastest-staining surfaces in the region. In communities like Julington Creek, Fruit Cove, Nocatee, and the master-planned neighborhoods of St Johns, it is common for a concrete driveway to go from fresh to stained within one or two rainy seasons.
The dark streaks you see are usually a combination of mold, mildew, algae, and embedded organic matter. Red clay staining from St Johns County soil gets pressed deeper with every vehicle pass. Oil spots and road film add another layer. Once the surface gets porous and stained, regular rain and a garden hose do almost nothing — you need a surface cleaner, the right detergent, and controlled pressure to actually lift the contamination out.
What driveway pressure washing covers.
A driveway cleaning with St Johns ProWash covers more than just the main apron. Most jobs include:
- Concrete driveway surface with surface cleaner attachment for even, streak-free results.
- Sidewalks and approach areas from the street to the front entry.
- Garage approach and pad around the garage door.
- Driveway borders, retaining edges, and transition strips.
- Driveways with red clay staining, mold, oil, or tire marks.
- Pavers and brick driveways that need low-pressure cleaning to protect joint sand.
Kolby uses a surface cleaner — a spinning, enclosed pressure head — rather than an open wand, which eliminates the striping and uneven lines that make DIY pressure washing look worse than before. The result is a flat, even clean across the entire slab.
Concrete cleaning vs. paver driveway cleaning — the method matters.
Concrete and paver driveways are cleaned differently. Concrete handles more direct pressure, so the surface cleaner can run at a higher PSI without risk. Paver driveways — especially travertine, brick, or interlocking concrete pavers — need a lower pressure setting to avoid displacing joint sand or damaging the surface texture.
For paver driveways that are heavily stained or have weed growth in the joints, cleaning is usually paired with re-sanding and sealing. That process restores the joint structure, locks out weeds, and protects the paver surface from the next season of Florida humidity and organic debris. You can learn more on the paver sealing page.
