Most Columbia, SC homeowners pay $275–$650 for a professional soft-wash house cleaning — siding, trim, and soffits. Smaller single-story homes with light buildup land toward the lower end of that range; two-story homes, larger square footage, and heavy algae or mildew coverage push toward the upper end and sometimes beyond it. These figures reflect the typical Columbia, SC market as of 2026, not a quote from any single company.

What Drives the Price
Siding Material
Vinyl siding is the most common material in the Columbia area and is generally straightforward to soft-wash. Painted wood, stucco, and brick each require different solution strength and dwell time — stucco and older painted trim need a gentler touch to avoid stripping paint or driving water behind the surface.
Stories and Square Footage
A single-story, 1,500-square-foot home takes less time and less solution than a 3,000-square-foot two-story home. Two-story homes also require extension equipment and more careful technique to reach the upper elevation safely.
Algae, Mildew, and Pollen Buildup
This is the variable most specific to the Midlands. Columbia's humid subtropical climate keeps north-facing and shaded walls damp for long stretches, which is exactly what black and green algae (commonly Gloeocapsa magma) needs to establish itself. A home that hasn't been washed in three-plus years, or one shaded by heavy oak or pine canopy, typically needs more solution and a longer dwell time than a home on a regular schedule.
Accessibility
Fenced yards, locked gates, landscaping crowding the foundation, and limited spigot access can all add time to a job.
Why Soft Wash Costs What It Does — And Why It Should
Soft washing costs a little more in cleaning solution than simply blasting siding with a pressure washer, but it's the method that actually kills algae and mildew at the root instead of just knocking the visible growth loose. Pressure washing removes what you can see; soft washing keeps it from coming right back within weeks. A quote noticeably cheaper than the ranges above is worth a second look — it often means high-pressure blasting on siding, which risks forcing water behind panels and stripping paint. See the full comparison in Soft Wash vs. Pressure Wash.
Signs You're Being Quoted the Wrong Method
- A quote that doesn't mention "soft wash" anywhere for siding
- A price based only on a flat per-square-foot rate with no mention of algae/mildew severity
- No plant or landscaping protection step included
- A deposit required before any work has been seen
Red Clay, Pollen, and Why Columbia Homes Need This More Often
Two things are specific to the Midlands and worth planning around: spring pine and oak pollen coats siding, screens, and driveways in a yellow-green film almost overnight, and Columbia's red clay soil splashes and stains lower siding during heavy rain. Neither is dangerous, but both build up fast in a climate this humid — which is why most local homes need attention more often than the same home would in a drier region.

Frequently Asked Questions
How much does house washing cost in Columbia, SC?
For most single-family homes in the Columbia, SC market, a professional soft-wash house cleaning typically runs $275–$650. Smaller single-story homes with light buildup land toward the lower end; two-story homes, larger square footage, or heavy algae/mildew coverage push toward the upper end and beyond. These are typical Columbia-market ranges — call or text (803) 717-3217 for a firm, no-deposit quote on your specific home.
Why does house washing cost more than a driveway of similar size?
Siding is soft-washed — chemistry at roughly garden-hose pressure, applied to kill algae and mildew at the root — while a driveway is pressure-washed with a surface cleaner. Soft-wash solution, dwell time, and the extra care required around windows, outlets, and landscaping generally make it a more involved job per square foot than flatwork.
How long do house washing results last in Columbia, SC?
House washing typically holds up 12–18 months before algae or mildew becomes visible again. Heavily shaded, north-facing walls under oak or pine canopy are always first to regrow, and anything within sight of open water — Lake Murray, for example — tends to regrow faster than the same wall a mile inland.
Does bundling house washing with a driveway clean save money?
Yes. Washing the full exterior plus the driveway and walkways in one visit is almost always cheaper per surface than booking them separately, since setup and travel time are shared. Expect roughly $100–$300 added to the house-washing price for a driveway bundle, rather than paying for a fully separate driveway visit.
