Paver Cleaning in
West Palm Beach, FL

On the western side of West Palm Beach, the single most common thing we are called to remove is not algae or grime — it is orange. Irrigation out there runs on well water, and well water in this part of the county carries dissolved iron. Every cycle, the sprinkler heads throw a fine mist across the driveway and walkway edges, the water evaporates, and the iron oxidizes into a rust stain that follows the exact arc of the spray pattern. Homeowners usually try a pressure washer first, then bleach, and neither does anything, because the stain is not sitting on the surface: it is a chemical bond in the top layer of the paver. Bleach can actually set it.

The treatment that does work is an oxalic-based rust remover, and it is a careful process rather than a quick one. We mask and pre-wet the landscaping, apply the product to the stained bands, let it dwell without letting it dry out, agitate with a bristle brush, then neutralize and rinse thoroughly so no residue is left behind to keep working on the paver. Heavy staining sometimes wants two passes. Once the surface is clean, the general wash follows: a biodegradable cleaning solution across the whole field so the treated bands do not sit as bright patches on a dirty driveway.

The part we always say out loud is that cleaning does not fix the cause. Unless the sprinkler heads that overspray onto hardscape are adjusted or a filter goes on the well line, the rust rebuilds within a season or two. Cleaning, then sealing — from $1.10/sq ft — buys a great deal of time by giving the iron a film to sit on instead of a porous surface to bond with, but the real fix costs about twenty dollars in sprinkler heads and a conversation with whoever maintains the irrigation.

The historic districts are the opposite problem. El Cid, Flamingo Park, and Old Northwood sit under protected live oaks and black olives, and that canopy drops tannins onto pavers year-round while holding enough shade that the surface stays damp through the morning. The result is a driveway that reads brown under the drip line and green along the shaded edges — tannin dye plus algae and mildew, two different problems that need two different products in the same visit. Nobody is removing the tree; the canopy is the reason those streets look the way they do, and in a district with design review the pavers are the element expected to adapt.

So we clean gently and often rather than aggressively and rarely. Soft wash pressure, an oxygenated biodegradable cleaner with real dwell time, hand agitation with a bristle brush along the darkest bands, and a controlled rinse that leaves the joint sand intact. On a hundred-year-old streetscape, blasting a surface clean at high pressure is how you scar the paver face and expose aggregate — the surface then holds dirt worse than it did before, and every subsequent clean has to work harder. Regular maintenance on a light touch beats an annual assault every time.

East of Olive, close to Flagler Drive, add the tide. King tides push brackish water onto low-lying hardscape in the fall, and the residue left behind is mineral, not organic — a fresh-water rinse after those events is the single most useful thing a waterfront owner can do between professional cleanings. When the wash is finished, we check the joints, re-sand anything the tides or the rinse have opened, and let you know honestly whether the surface is ready to seal or wants a full dry-out first. Sealing damp pavers in West Palm's humidity is how the white hazing you see on neighbors' driveways happened.
