Driveways and flatwork

Why the surface cleaner pays for itself

Flatwork is where pressure is the tool. A wand cleans concrete in a 3-inch fan, leaving zebra stripes and eating your morning. A surface cleaner, the round wheeled head with two nozzles spinning under a shroud, cleans a 15 to 20 inch swath evenly and holds the nozzles at a fixed height, which is what prevents the striping. Operators report the same arithmetic: a driveway that takes three to four hours with a wand takes about 45 minutes with a surface cleaner on a 4 GPM machine. That tool is the entire difference between $50 an hour and $150 an hour on concrete.

Technique in five rules. Overlap each pass by about a quarter of the cleaner's width so no uncleaned ribbons survive between passes. Move at a steady walking pace; speed shows up as patchiness. Keep the cleaner flat on the surface, both wheels down. Work in a pattern, usually the long dimension of the slab, and do the edges and corners with the wand last, feathering to blend. Then post-treat: many operators apply a light SH or brightener mix after pressure cleaning to even out tone and lift the remaining gray, the step that separates a clean driveway from a driveway that photographs well.

Pricing concrete

Driveway pricing is per square foot, with a minimum. Survey data puts driveway cleaning at $0.25 to $0.35 per square foot and a typical total of $155 to $190 (HomeGuide); contractor guidance gives a wider $0.10 to $0.40 band (HomeGuide). Working operators report $0.15 to $0.19 per square foot in their market, discounting the concrete when it rides along with a house wash because you are already set up. Measure the slab (length times width, minus a bit for the garage apron you will also do), apply your rate, adjust for condition, and quote a number.

Walkways and patios price the same way and are natural add-ons: the customer watching you do the driveway is already sold on the result, and the setup cost to you is ten minutes. Pool decks and pavers are cousins of the same work, though pavers bring joint sand concerns (keep pressure off the sand lines or plan to re-sand) and sealed surfaces need a chemical-only approach.

Stain work: the referral machine

Flatwork is also where stain chemistry lives, and stain removal is the skill neighbors talk about. Rust stains (fertilizer, battery acid, well water) come off with dedicated rust remover, an acid-side product used strictly per label. Oil and grease spots get a degreaser, dwell, and a hot-water-grade rinse if you ever add a hot machine. Tire marks on a driveway apron respond to stronger alkaline cleaners. Two disciplines: never let acid-side and chlorine-side products mix in a bucket or on a wet surface, and always neutralize and rinse per label, because residue keeps working after you leave.

Quote stains as line items, not included freebies. "Driveway cleaning, $190; rust treatment on the walk, $45" is honest, profitable, and teaches the customer that chemistry is a skill with a price. Bundling still works: quote the package total out loud while pointing at each element.

One more flatwork habit with an outsized payoff: the drain check. Driveway rinse water heads for the street gutter and the storm drain, which is exactly what "Legal, insurance, and the water rules" says you cannot let happen unchecked. Dam the drain, vacuum or pump the pooled water to a sanitary outlet or the lawn, and keep the degreaser-laden water out of the storm system entirely.

That is the second of the four services. The craft section continues with the remaining two.
