Concrete looks tough, but it's porous. Left alone, driveways, sidewalks, patios, and garage floors in West Columbia collect algae, red clay staining, oil drips, tire marks, and the greenish-black film that shows up fast in our humid summers. Driveway and concrete cleaning uses hot or cold water pressure washing, sometimes paired with surface cleaners (those spinning wand attachments) and degreasers, to strip that buildup back to the original slab color without gouging or etching the surface.
We're tracking 11 businesses in West Columbia that offer this work. Quality varies more than people expect. A rushed job with too much pressure at a bad angle can leave stripe marks, chew up the surface, or blow out mortar joints between pavers. A good crew adjusts pressure and nozzle choice for the surface, pre-treats oil stains and organic growth, uses a surface cleaner for even coverage on large slabs, and rinses and directs runoff away from grass and flower beds.
Before hiring, ask what PSI and equipment they use on concrete, whether they use hot water (better for grease and oil), how they handle staining and pitting, and if they carry insurance in case of property damage. Get a clear answer on turnaround time and whether they seal the concrete afterward, since sealing extends how long the clean lasts.
Our ranked guide to West Columbia pressure washers scores providers on the factors above, and our methodology page lays out exactly how we weigh and verify them.
