Driveway Cleaning
in Charleston, SC

Driveway cleaning in Charleston typically runs $150 to $400 depending on size, condition, and stain severity. A standard single-car driveway with light mildew runs $150 to $200. A two-car driveway with moderate green and a few oil drips runs $200 to $300. Long shared driveways, three-car widths, or driveways with serious oil staining and curbside aprons run $300 to $400. Bundling with house washing or roof soft washing on the same visit saves $50 to $100 because equipment mobilization is shared.

Annually is the baseline for inland Charleston driveways. Coastal homes within five miles of the Atlantic (Sullivan's Island, Isle of Palms, Folly Beach, Kiawah, Seabrook, Daniel Island) need twice-yearly cleaning because salt and humidity drive faster mildew growth. Driveways under heavy live oak canopy on Johns Island or in Old Mount Pleasant typically need cleaning every 9 to 12 months. If you can see any green tint, dark parallel streaks, or distinct shadows under the parking spots, you're overdue.

Yes, if it's done wrong. Hand-held wand cleaning at 3,500 to 4,000 PSI on a narrow tip etches visible stripes into the concrete that won't come out without resurfacing. The fix is to use a dedicated surface cleaner (a shrouded spinner bar with two calibrated nozzles) that maintains consistent pressure across the whole driveway. We never wand-wash a driveway. We use a surface cleaner first, then detail the edges and joints with a wand at lower pressure. Done correctly, professional cleaning is completely safe for residential concrete.

Not for 12 to 18 months when we do it right, because the cleaning solution kills the algae and mildew at the root, not just on the surface. A pure pressure-only rinse without chemistry just removes what's visible; the spores are still there and regrow within 6 to 8 weeks. Our process applies a biodegradable cleaning solution (chlorine-based for mildew, oxygenated for tannin), gives it dwell time to penetrate the porous surface and kill the organism, and then rinses everything clean. That's why a real driveway cleaning lasts a year, not a month.

Yes, both. Stamped concrete and exposed aggregate need lower pressure than smooth poured concrete because the textured surface is more vulnerable to chipping and scrubbing damage. We adjust our surface cleaner spinner bar pressure down for these surfaces and use a 40-degree tip on the wand for edge detailing.

Yes, both, with adjusted technique. Asphalt cleaning uses lower pressure (around 1,500 PSI) and a wider tip to lift dirt and stains without damaging the binder. Brick and concrete paver driveways need careful technique because high pressure blows out the polymeric sand between the joints, so we use a dedicated paver-cleaning approach with the surface cleaner set at low pressure and a paver-safe cleaning solution. After cleaning paver driveways we recommend re-sanding the joints to maintain stability; we coordinate that with you during the visit.

A standard single-car driveway takes 45 to 90 minutes including setup, surface cleaner pass, edge detailing, and final rinse. Two-car driveways run 90 minutes to 2 hours. Larger or heavily stained driveways can take 2 to 3 hours. Bundling with adjacent surfaces (sidewalks, walkways, the front porch) typically adds 30 to 60 minutes per surface. We schedule driveway cleanings as half-day windows so we never rush the dwell time on stains. That's the part that determines whether the result holds for a year or three months.

Yes. Annual maintenance plans are the most common arrangement for our regular driveway clients. We track each property's cleaning date and proactively reach out when the next visit is due. Maintenance-plan clients get priority scheduling, locked-in pricing, and a 10 to 15 percent discount versus one-off pricing. Most clients on annual plans schedule the cleaning ahead of HOA covenant inspection windows in Daniel Island and Mount Pleasant, ahead of pre-listing photoshoots if they're selling, or ahead of the spring entertaining season for personal use.
