What Upstate homeowners actually pay to soft-wash their siding, plus the size, siding type, and algae severity that move the number up or down.
House washing is the job most Greenville homeowners book first - it is the single biggest surface on the property, and green algae and pollen film on the siding are impossible to miss from the street. So the first question is almost always the same: what does it cost? Here is a straight look at what Upstate homeowners actually pay to wash a house in 2026, and what pushes the number up or down.
For a standard single-story home, a full soft-wash house washing usually runs in the low-to-mid hundreds. Two-story homes and large footprints land higher because there is more square footage to cover and more reach and setup involved. Prices are driven by the size of the house and how heavy the buildup is - not a flat per-house rate - so a compact ranch in the West End costs noticeably less than a big two-story out in Five Forks. Most companies here, ours included, price the whole exterior wash as one flat, upfront number rather than by the hour.
Four things drive the price the most in the Upstate. First, size and stories: more wall area and a second story mean more time and more careful reach. Second, the siding material - vinyl and fiber cement wash quickly, while older brick, stucco, and painted wood need a gentler, more deliberate approach that takes longer. Third, how heavy the growth is: a home coated in years of green algae and black mildew takes more cleaning solution and more dwell time than one washed last spring. That is a big factor here, because north-facing walls and shaded, tree-covered lots around Easley and the foothills grow the thickest algae in the region. Fourth, access - steep lots, tight side yards, and heavy landscaping against the house all slow the job down.
If a quote is rock-bottom, it almost always means high pressure and no cleaning solution. Blasting siding with a pressure wand can crack aging vinyl, force water up behind the panels where it grows hidden mildew, and strip paint off wood and trim. It also does not actually kill the algae - it just knocks the surface film loose, so the green is back within weeks. A proper house washing in Greenville uses a low-pressure soft-wash with a professional cleaning solution that dissolves the algae, mildew, and pollen and kills it at the root, so the siding stays clean for a year or more instead of a month. You are paying for the growth to actually die and stay gone - and for your siding to survive the process. For more on why the method matters, see soft-wash vs pressure washing.
Because a big part of any job is showing up and setting up, the cheapest way to wash a house is rarely to book the siding on its own. Adding the driveway and concrete, a roof cleaning, or gutter brightening to the same visit spreads the trip cost across more surfaces, and the roof and siding both need the same soft-wash treatment anyway. Homeowners across Simpsonville and southern Greenville County tend to book the whole exterior once a year rather than piecemeal, which keeps the per-surface cost down. For how the other surfaces price out, see our Greenville pressure washing cost guide.
The fastest way to a real number is a couple of phone photos of the house - ideally the shadier, algae-heavy sides - plus a note on how many stories it is and what the siding is made of. That lets us size the job and quote a flat, upfront price with no surprises on the day.
