Pressure Washing Cost Guide for Charleston Homeowners

Quick answer

Most Charleston homeowners pay $300-700 for a full-house exterior soft wash, $150-400 for driveways and walkways, and $400-800 for roof soft washing. Exact price depends on home size (square footage of exterior surface), height (single vs. two-story), surface type, and severity of growth. A whole-property package typically lands at $600-1,200. Quotes should be itemized by surface and provided in writing before any work begins.

What drives the price up?

Five factors affect what you pay:

• Home square footage - more siding to clean = higher cost
• Height - two-story and three-story homes need taller equipment
• Surface type - stucco and brick take longer than vinyl
• Growth severity - heavy black mildew or moss takes more solution and dwell time
• Access - fenced yards, steep grades, tight gates slow the job

What does a typical full-property quote look like?

For an average 2,000 sq ft single-story home in the Lowcountry region:

• House soft wash (siding, soffits, eaves): $350-500
• Driveway pressure wash: $150-250
• Front walkway + porch: $80-150
• Back patio: $100-200
• Bundle total: $680-1,100

How can you tell if a quote is fair?

Three signs you’re getting a fair quote:

• It’s itemized by surface, not a flat lump sum
• It specifies soft wash vs. pressure wash by surface
• It’s written, not verbal

Frequently asked questions

Why are some quotes much cheaper than others?

Cheap quotes often skip the cleaning solution and just rinse with high pressure. The result looks clean for a week, then growth returns. Real soft washing requires solution, dwell time, and rinse - that’s reflected in the price.

Are pressure washing services tax-deductible?

For homeowners, no - personal expense. For rental property owners, exterior maintenance is deductible as a repair. For commercial properties, fully deductible.

Do you offer recurring service plans?

Many contractors offer twice-yearly maintenance plans at 10-20% off single visits. Worth asking.
