Concrete & Driveway Cleaning

Concrete driveways and walkways grow algae and moss in shaded areas, and they accumulate oil drips, tire rubber, and dirt. Moss makes concrete slippery and holds moisture that accelerates freeze-thaw cracking. Oil stains don't just look bad — they penetrate porous concrete and spread over time. AWP Exterior Cleaning pressure-washes concrete at 3,000–4,000 PSI using a surface cleaner attachment.

Surface cleaners have rotating nozzles under a shroud, which prevents streaking and controls overspray. The result is even cleaning without the tiger-striping that happens when you use a wand alone. Oil stains get pre-treated with degreaser and hot water when available. Old oil stains that have soaked deep into concrete may lighten but won't disappear completely — concrete is porous, and oil migrates below the surface. Fresh stains come out; year-old stains don't.

The crew rinses landscaping and covers plants near the work area. Runoff from concrete cleaning contains dirt, oils, and cleaning agents, so it's directed toward storm drains or gravel areas, not onto lawns or garden beds. Most residential driveways across Greater Clark County take 1–2 hours depending on size and staining. Patios and walkways add time based on square footage. Heavily stained or textured concrete takes longer than smooth, lightly soiled surfaces.

AWP provides before-and-after photos for every job, and if you're not satisfied with the results, let them know within 48 hours — they'll come back at no charge. Payment is due on completion unless invoicing has been arranged.
