Pressure Washing Cost in Columbia, SC — What to Expect (2026)

Several things move the price up or down on a pressure washing job. Surface type matters: concrete driveways are priced differently than wood decks, vinyl siding, or brick. Size is the biggest driver — more square footage means more time and water. Condition is the third factor. A driveway with years of oil stains, mold, or algae buildup takes longer to clean than one that just needs a seasonal wash. In Columbia's humid climate, mold and algae grow faster than in drier regions, so buildup can accumulate faster between cleanings.

Driveways (concrete): $150–$300 for a standard two-car. Decks and patios: $200–$400 depending on size and material — wood requires lower pressure and different techniques than composite. House exteriors: $250–$500 for a single-story home, more for two-story. Gutters (exterior face): $75–$150 when added to a house wash. Sidewalks and walkways: $50–$150. These are Columbia metro rates. Some contractors price by square foot; others by flat rate per job. Either approach is valid as long as you know what's included.

High-pressure washing works well on hard surfaces: concrete, brick, and pavers. We use it on driveways, walkways, and patios. Soft washing — lower pressure with cleaning solution — is the right method for roofs, painted siding, wood, and anything that could be damaged by high PSI. The cost is similar, but the chemistry is different. If a contractor wants to high-pressure wash your roof or painted wood siding, that's a red flag — those surfaces need soft washing.
