How Much Does Pressure Washing Cost in South Carolina? 2026 Rates From the Upstate to the Lowcountry

A lot of South Carolina homeowners do not schedule a wash because the house looks dirty. They schedule it because a letter arrived from the HOA. Coastal communities in Hilton Head, Mount Pleasant, Bluffton, and Myrtle Beach routinely enforce exterior cleanliness covenants, and a green north wall is the fastest way to get a violation notice.

The going rate in 2026 is $250 to $600 for a house wash, $125 to $325 for a driveway, and $600 to $1,200 for a full property package covering siding, concrete, and gutters. Charleston and Beaufort County pricing sits 10 to 20 percent above the Upstate for the same square footage.

Frequency is the part that separates South Carolina from most of the country. Inland homes need cleaning every 18 to 24 months. Within a few miles of salt water, a year is the realistic interval, and shaded elevations sometimes need attention twice a year.

HOA Covenants Set the Schedule on the Coast

Most planned communities in Beaufort, Horry, and Charleston counties include maintenance language in their covenants requiring exteriors to be kept free of mildew and discoloration. Enforcement varies, but in the larger managed communities it is routine, and letters go out after the spring and fall property inspections.

The practical result is that coastal South Carolina homeowners tend to run an annual contract rather than calling when things look bad. Annual service agreements price 10 to 20 percent below one-off visits because the company can route several houses in a neighborhood on the same day.

If you own a rental or a second home on the coast, that scheduled approach also protects your rental listing photos and keeps you clear of the violation process while you are out of state. Ask the management company what their inspection months are and book two weeks ahead of them.

What Companies Charge, Region by Region

Pricing follows population density and travel time more than anything else. A crew working a tight route in Mount Pleasant covers six houses in a day. A crew driving out to a property outside Walterboro covers two.

House washing on a single-story ranch of 1,200 to 1,600 square feet runs $200 to $375. Two-story homes of 2,400 to 3,200 square feet run $375 to $650. Raised coastal homes on pilings, common from Edisto down through Hilton Head, add $75 to $200 because the crew has to clean the underside framing and the stair systems.

Concrete is priced per square foot at $0.12 to $0.30. A standard driveway of 600 square feet lands at $125 to $250 as a standalone job, less when bundled. Tabby concrete and exposed aggregate need lower pressure and cost slightly more per foot.

The Lowcountry Premium

Salt aerosol is the reason coastal jobs cost more. It settles on every surface, holds moisture, and gives mildew a permanent foothold. Contractors compensate with stronger solutions, longer dwell times, and a more thorough freshwater rinse, and all of that is labor.

Historic Charleston properties are their own market. Old stucco over brick, lime mortar, and original wood siding tolerate almost no pressure, and cleaning them is hand work with soft brushes and mild solutions. Expect $600 to $1,500 for a single historic facade, and expect the company to say no if they are not experienced with it.

Upstate and Midlands Pricing

Greenville, Spartanburg, Anderson, and Columbia sit in the lower half of the state's range. The same 2,500 square foot two-story that costs $600 in Mount Pleasant often costs $425 in Greer.

The dirt is different too. Upstate homes deal with red clay splash on foundations and lower siding, pine pollen, and shade-driven algae rather than salt. Clay staining on concrete needs an oxalic acid treatment, which adds $75 to $200 to a driveway job.

Surfaces That Need a Light Touch

South Carolina builders have used a lot of stucco and synthetic stucco over the past 30 years, particularly in coastal and Midlands subdivisions. Pressure on EIFS cracks the finish coat and drives water into the foam behind it, and the repair costs far more than the wash. These surfaces get soft washed at low pressure or they get damaged.

Fiber cement siding is the other big one. It holds up well to soft washing but the butt joints and the bottom edge take water intrusion badly under a concentrated stream. Painted wood on older homes in Camden, Aiken, and downtown Columbia will lose paint in sheets under a 3,000 PSI tip.

Soft washing solves all three. It runs at roughly 100 to 500 PSI with a diluted sodium hypochlorite mix and a surfactant, killing the organism at the root rather than blasting the top layer off. Cleaned that way, siding stays clean noticeably longer.

The tradeoff is landscaping. South Carolina foundation plantings are dense, and camellias, azaleas, and ferns burn quickly if the crew does not pre-wet the beds, tarp what it can, and rinse afterward. Ask exactly how they handle that during the estimate.

Roof Cleaning and Gutter Brightening

Those dark streaks running down asphalt shingles are algae, and in South Carolina's humidity they appear within six to eight years of a new roof. Soft washing a 2,000 square foot roof runs $450 to $1,000.

High pressure on shingles strips granules and voids the manufacturer's warranty. Any company that offers to pressure wash a shingle roof should be removed from your list on that basis alone.

Gutters are usually a separate line item. The black vertical striping on the outside face is oxidized aluminum combined with road film, and it needs a dedicated brightening product and hand agitation. Budget $1.00 to $2.50 per linear foot.

How to Vet a South Carolina Contractor

South Carolina does not license pressure washing as its own trade, so the entry cost is a trailer and a machine. Insurance is your real screen. Ask for a certificate of general liability at $1,000,000 or more sent directly from the agency, plus proof of workers' compensation if the company has employees.

Get the scope in writing with each surface priced separately. "Wash the house" is not a scope. Naming all four elevations, the soffits, the gutter faces, the front walk, and the driveway square footage is.

Ask three specific questions: what pressure will you use on my siding, how do you protect the plantings, and do you rinse the windows afterward. Contractors who answer all three without hesitating tend to be the ones whose reviews do not mention streaks and dead shrubs.

Pulling several bids on identical scope is how outliers become obvious. Our listings of pressure washing companies working across South Carolina are organized by city, and our other South Carolina home service cost guides apply the same comparison method to roofing and gutters.

Best Time of Year to Book

South Carolina's mild winters mean soft washing runs nearly year round, and January and February are the cheapest months to buy it. Crews are slow, routes are short, and discounts of 10 to 15 percent are common.

Late spring, after oak and pine pollen finish in early May, is the most popular window. Book it three to four weeks ahead because that is when everyone else is calling.

Avoid washing during the height of a Lowcountry August if you can. Solutions dry on hot surfaces before they can work, and crews either start at dawn or produce mediocre results. Reputable companies will tell you that themselves.

Hurricane season adds one more consideration. After a storm passes through Charleston or Georgetown, the salt and organic debris deposited on siding is worth removing sooner rather than letting it sit through the fall.

Questions South Carolina Homeowners Ask

How often should I pressure wash my house in South Carolina?

Once a year within a few miles of the coast, and every 18 to 24 months inland. Shaded north-facing walls under live oaks often need attention on a shorter cycle than the rest of the house.

Will a soft wash remove the green growth for good?

It kills what is there, and the surface usually stays clean for 12 to 24 months depending on shade and humidity. Nothing prevents regrowth permanently in this climate, though some companies offer a treated finish rinse that extends the interval by a few months.

Can pressure washing damage stucco?

Yes, and it is a common expensive mistake in coastal subdivisions. Synthetic stucco takes water behind the finish coat under pressure, so stucco and EIFS should be soft washed at low pressure only.

Is it safe to clean a roof with algae streaks?

It is when done as a low-pressure chemical soft wash. That is the method the asphalt shingle industry endorses, and it costs $450 to $1,000 on a typical South Carolina roof.

Does my HOA have to approve the contractor?

Usually not, though some managed communities on Hilton Head and Kiawah require vendors to carry specific insurance limits and register before working on site. Check the vendor rules before scheduling to avoid a crew getting turned away at the gate.
