Driveway (2-car, 400-600 sq ft): $150-$250. Driveway (3-car or oversized): $250-$400. Red clay pre-treatment: add $50-$100. House exterior (soft wash, up to 2,000 sq ft): $250-$400. House exterior (2,000-3,500 sq ft): $400-$650. Two-story premium: add $100-$200. Patio or pool deck (200-400 sq ft): $100-$200. Wood deck (wash + brightener): $150-$300. Composite deck: $125-$250.

These are mid-2026 Columbia market rates based on actual service pricing, not national averages.

Most Columbia pressure washing companies offer bundle discounts when you combine multiple surfaces on one visit. A typical full-property bundle (driveway + house exterior + patio) saves 15-22% vs. booking each separately. Example: driveway ($200) + house ($400) + patio ($150) = $750 individual vs. $600-$650 bundled. Annual maintenance contracts save an additional 10-15% per visit. The savings come from reduced mobilization cost -- the crew is already on-site with equipment running. We price bundles transparently with line-item breakdowns so you can see exactly what each service costs individually and what you are saving.

Concrete (driveways, sidewalks, patios): $0.15-$0.35 per sq ft. These are the most straightforward jobs -- commercial surface cleaners produce streak-free results in a single pass. Vinyl siding (soft wash): $0.08-$0.15 per sq ft. Lower pressure, higher chemical cost. Brick: $0.10-$0.20 per sq ft. Requires careful pressure control to avoid mortar damage. Wood decks: $0.75-$1.50 per sq ft including brightener treatment. Composite decks: $0.60-$1.00 per sq ft with non-bleach cleaner. Roof shingles (soft wash only): $0.20-$0.35 per sq ft. Never pressure wash -- soft wash kills algae without loosening granules.

Surface area is the primary driver. Beyond that: staining severity (red clay, oil, heavy biological growth require pre-treatment that adds $50-$150), access difficulty (gates, tight spaces, second-story reach), surface material (soft wash chemicals for delicate surfaces cost more than water pressure alone), and property condition (first-time cleaning after years of neglect costs 30-50% more than annual maintenance). Shaded driveways and north-facing walls accumulate growth faster and take longer to clean. Lake Murray and river-adjacent properties have higher humidity and need more frequent service, which actually lowers per-visit cost through recurring contracts.

Storefronts and sidewalks: $0.08-$0.15 per sq ft. Parking lots: $0.05-$0.10 per sq ft. Dumpster pads (with degreaser): $75-$150 per pad. Building facades: $0.10-$0.20 per sq ft. Drive-throughs: $150-$300. Loading docks: $100-$250. HOA common areas: priced by contract (monthly or quarterly). Restaurants typically need monthly dumpster and grease pad cleaning at $75-$150 per visit. Regular commercial contracts run 15-20% less per visit than one-time calls. Most commercial work is scheduled during off-hours (before 7 AM or after close).

Winter (December-February) is the slowest season for pressure washing in Columbia, and many companies offer 10-15% discounts to fill the schedule. Concrete cleaning works fine in winter as long as temperatures are above 40 degrees. Spring (March-May) is peak season -- highest demand, longest wait times, full pricing. Summer is moderately busy. Fall (September-November) is a good value window -- moderate demand, reasonable pricing, and a pre-holiday property refresh. If flexibility matters more than timing, booking in January or February for a late-February appointment gets the best rate.

Renting a consumer pressure washer: $75-$150/day plus chemicals ($20-$40). Your time: 4-8 hours for a driveway and house. Total DIY cost: $100-$200 plus a full day's work. Professional cost for the same scope: $400-$700. The professional brings commercial equipment that cleans 3-5x faster, knows which surfaces need soft wash vs. pressure, carries insurance for accidental damage, and the result lasts longer because root-level biological growth is killed rather than just blasted off the surface. The real risk of DIY: using too much pressure on vinyl siding (drives water behind the cladding), too much pressure on wood decks (furs the grain, requires sanding), and no pre-treatment on biological growth (it grows back in 2-3 months instead of 12-18).
