Concrete Cleaning in Brunswick, GA: Sidewalks, Steps, Porches and Walkways

The flatwork on a typical Glynn County property adds up fast. A front walk from the street to the door. Two or three steps and a landing. A porch slab. The apron where the garage floor meets the drive. A back patio slab. A stretch of curb and gutter pan along the street. On a small commercial exterior, it's the sidewalk out front, the entry landing and the pad by the back door.

All of that is this job.

The driveway isn't. The poured concrete, pavers, brick or exposed aggregate that makes up the actual drive gets quoted and cleaned as its own job, with its own page. That's a scope line—a two-car drive is a different amount of surface and a different amount of time than a front walk and three steps.

A pool deck isn't this job either, even when it's plain poured concrete. Anything around pool water runs under a separate water-protection protocol, and screened lanais and pool cages come with it—a different job with its own scope.

Our truck starts at 1136 Autumns Wood Cir on the north side of Brunswick, off the Golden Isles Parkway. Flatwork in town, out toward Sterling, in Dock Junction and Country Club Estates, and across the Torras Causeway on the islands—all on the regular route.

Concrete is one of the few surfaces on a house that can take real pressure. It gets it.

Before any water touches the field, the concrete is pre-treated with a cleaning solution and given dwell time—and that step matters more than the pressure does. Algae has roots into the pores of the concrete. A water-only spray takes off the top layer of green while leaving what's underneath alive to grow straight back. Pre-treatment kills it at the root, which is why a pre-treated slab holds its clean longer than one that was only blasted with water.

Then the field gets run with a rotary surface cleaner: a shrouded head with bars that spin underneath it, so the water hits the slab at a consistent distance and a consistent speed across the whole surface. That's what produces an even finish from one edge to the other.

A wand held in a hand can't do that. The tip sits closer in some passes than others, the operator's arc slows at the end of each sweep, and the result is pale stripes and arcs baked into the concrete that show up worse once it dries. Those wand stripes don't come out. The only fix is cleaning the whole slab again, evenly.

The wand still has a job here, just a narrow one—edges the surface cleaner can't reach, expansion joints, corners where the slab meets a wall or a step riser, individual stains that need direct attention. Field work is the surface cleaner. Detail work is the wand.

Same method as a driveway, just applied to smaller and more awkward pieces of flatwork—which is why a stack of steps takes longer per square foot than an open patio slab does.

Here's what a pre-treated, surface-cleaned slab actually looks like afterward.

Green algae comes out. Black mildew comes out. Leaf tannin staining from the oaks comes out. Pollen film, mud splash, general dirt—all of it comes out. On most walks, steps and porch slabs in this county, that's the entire problem, and the concrete goes back to the color it was poured in.

Some things aren't dirt, though, and they behave differently.

Orange rust from well-fed irrigation is everywhere in coastal Georgia, and it doesn't respond to pressure at all—you can run a surface cleaner over a rust stain until the concrete is wet through and the orange is still sitting there. Rust needs a rust remover made for concrete, applied by hand to the stain. Fresh rust generally comes out. Rust that's been feeding on the same spot for years may only fade.

Oil is the same kind of problem. An oil stain by a garage door has soaked down into the pores, so a degreaser and hand work lift what's in the top of the slab. A deep, old stain often leaves a ghost.

Etching works differently. Where minerals or a harsh chemical have eaten into the surface of the concrete, the concrete itself is a different texture there—and no amount of cleaning changes texture.

We tell customers which of those they have before the job starts. If your walk is green, you're getting a clean walk. If your apron has an old oil stain in it, you're getting a much better apron with a shadow where the stain was—and it's better to hear that at the quote than to pay and be surprised.

Three boundaries, stated plainly.

The driveway surface itself is a separate job, quoted separately, with its own page. It's usually the largest single piece of flatwork on a property, and it's priced that way.

A pool deck, screened lanai or pool cage is also separate, even when the deck is plain poured concrete. Work around pool water runs under its own water-protection protocol, its own job, its own page.

We don't seal concrete or pavers. Not as an add-on, not at all.
