What areas of concrete does a Ripon cleaning cover?
Driveways, front walkways, entries, patio slabs and garage floors — each treated with pressure and chemistry matched to its exposure.
Driveways get the most traffic and the most staining: tire marks, oil drips, and the fine gray film that settles from Highway 99 and Jack Tone Road corridor traffic. These are pre-treated with a degreaser before the surface cleaner pass so oil doesn't just spread across clean concrete.
Walkways and entries near Downtown Ripon's tree-lined lots often sit in shade longer, which lets green algae and black mildew take hold in the pores of the concrete. Patio slabs and garage floors get checked for sealer or stain before cleaning, since a sealed patio needs lower pressure to avoid stripping the coating.
Every job includes edging along garden beds and expansion joints, where soil and grass clippings build a dark line that a straight surface-cleaner pass skips over.
Why does concrete in Ripon get dirty so fast?
Almond and walnut orchard dust, harvest-season shaking, and hard well-water irrigation all deposit residue that ordinary rain doesn't rinse away.
Ripon's orchards kick up heavy dust during August and September shaking, and that fine grit settles into concrete pores across the whole property, not just near the trees. Add mid-February to early-March almond bloom pollen, which is tannin-rich and stains lighter-colored concrete a dull yellow-brown where it collects in low spots.
Sprinklers and drip lines running on well water leave a chalky white-to-orange mineral haze along driveway edges and walkway borders, and winter Tule fog keeps shaded concrete damp long enough for algae to take root before the next dry stretch arrives.
Will pressure washing damage stamped or colored concrete?
Only if the pressure and tip are wrong — stamped and stained concrete need lower pressure and a wider fan than plain broom-finish slabs.
Stamped concrete carries color in a thin surface layer, often under a sealer, and a narrow high-pressure tip can haze the sealer or streak the color unevenly. We identify sealed or decorative concrete during the walk-through and adjust pressure and detergent accordingly.
Plain broom-finish driveways and garage slabs can take higher pressure since there's no coating to protect, which is why we always confirm the finish type before setting up equipment.
Flatwork in Ripon prices at $0.30 per square foot, so a 1,000-square-foot driveway-and-walkway package lands near $300.
Exterior Prime professionals clean Ripon concrete at 3,500 PSI behind a 20-inch surface cleaner, covering about 1,200 square feet per hour across 95366.
Tule fog keeps Ripon slabs damp from November through February, which is why most Ripon driveways need one wash every 12–18 months.
