Soft washing a house in Wilmington, North Carolina typically costs between $325 and $750, with the average single-family home landing around $450 for the full exterior. Two-story homes, heavily mildewed siding, and add-ons like gutter brightening can push the price toward the upper end. Nick and Chris Corbelli have been cleaning homes across the Cape Fear region for years, and this is one of the most common questions they hear.
Around 70 percent of homes within a few miles of the Cape Fear River show some level of green or black mildew growth on their siding by year three after construction. That number climbs higher in shaded neighborhoods like Landfall and Porters Neck, where mature oaks keep the north walls damp for hours after every rain. Soft washing is the only cleaning method that safely kills that growth without driving water behind your siding.
What Does a Soft Wash Actually Include in Wilmington NC?
A soft wash is a complete exterior siding clean using low-pressure spray and a biodegradable cleaning solution that kills mildew, algae, and bacteria on contact. Unlike a quick rinse, the solution is dwelled on the siding for several minutes so it can break the bond between the organic growth and the surface, then rinsed gently with water.
A standard Window Cleaning Wizards soft wash for a Wilmington home includes:
All vinyl, Hardie-board, brick, or stucco siding from the foundation to the roofline
Soffits, fascia boards, and the exterior of the gutters
Window frames, shutters, and exterior trim
Porch ceilings and column wraps
A pre-rinse of all flower beds, shrubs, and grass to dilute any drift
A post-rinse of every plant once we are finished
We also move and cover any potted plants and patio furniture before we start, then put everything back exactly where we found it. That single habit accounts for a noticeable chunk of our five-star reviews from homeowners in Mayfaire and Forest Hills.
How Is Soft Washing Different from Pressure Washing?
This is where most quote confusion starts.
Pressure washing is the use of high-pressure water, often 2,000 to 4,000 PSI, to physically blast dirt off hard surfaces like driveways and concrete patios. Soft washing is the use of low-pressure spray, typically under 500 PSI, combined with a chemical solution that does the actual cleaning work.
Sodium hypochlorite solution is the active ingredient in nearly every professional soft wash mix in the industry. When properly diluted and applied with a mildewcide, a wetting agent, and a rinse aid, it kills mildew at the root without damaging paint, vinyl, or landscaping.
The difference matters for your wallet and your house.
Feature | Soft Wash | Pressure Wash |
Best for | Siding, roofs, soffits, painted surfaces | Driveways, concrete, brick walkways |
Pressure used | Under 500 PSI | 2,000 to 4,000 PSI |
Cleans mildew at the root | Yes | No, only blasts surface |
Average Wilmington cost | $325 to $750 | $200 to $500 |
Typical job length | 2 to 3 hours | 1 to 2 hours |
Risk to siding | Very low | High if used incorrectly |
If a quote uses the words "house pressure wash" for siding, ask a follow-up question. Spraying high pressure on vinyl or Hardie-board can force water behind the panels, peel paint, and void manufacturer warranties. We covered that in detail in our guide to why you should never pressure wash your vinyl siding.
What Factors Change the Final Price of a Soft Wash?
Five things move a Wilmington soft wash price up or down within the $325 to $750 range.
Square footage of siding. A 1,400-square-foot ranch in Pine Valley sits at the bottom of the range. A 3,800-square-foot two-story in Landfall or Autumn Hall sits at the top. For a deeper breakdown of how square footage drives price, see our guide to house washing cost in Wilmington NC.
Number of stories. Reaching second-story siding safely requires longer telescoping wands, more solution, and more setup time. Two-story homes typically run $150 to $250 more than a single-story home of similar footprint.
Severity of growth. Light pollen and dust rinse off easily. Heavy black mildew on north-facing walls, common after a wet spring like the one Wilmington just had, requires a stronger solution mix and a longer dwell time. Heavily soiled homes can add $75 to $150 to the price.
Siding material. Vinyl and Hardie-board are the easiest. Painted wood, stucco, and older brick require gentler solutions and more careful rinsing, which adds a small premium.
Add-on services. Most homeowners bundle their soft wash with at least one other service. The most common add-ons:
Gutter brightening (removing those dark vertical streaks): add $75 to $150
Driveway pressure wash: add $150 to $300
Concrete patio or pool deck: add $100 to $250
Window cleaning at the same visit: add $200 to $400
A Wilmington homeowner in Forest Hills called us last week for a soft wash plus driveway, and the bundled price was about $90 less than booking each service separately. Bundling almost always saves money because we are already on site with the truck, hoses, and crew. We break down the full bundle pricing in our complete exterior cleaning bundle cost guide.

Is Soft Washing Worth the Cost for Wilmington Homeowners?
Yes, for almost every homeowner in our service area, and the math is not close. According to Angi's 2026 pressure washing cost guide, a professional house wash typically pays for itself in protected siding life and recovered home value within the first three years.
Wilmington's climate is brutal on siding. Salt air drifts inland from Wrightsville Beach and Carolina Beach, sticking to walls and feeding mildew. Summer humidity sits in the 80 to 90 percent range for weeks. Spring pine pollen coats every surface in yellow dust that traps moisture against the siding underneath.
Untreated mildew does not stay cosmetic. It eats into paint and the soft outer layer of vinyl, eventually pitting the surface so deeply that no amount of cleaning will restore the original color. We have seen homes in Ogden where the homeowner waited eight years between cleanings and the only fix was full siding replacement at a cost of $14,000 to $22,000.
A $450 soft wash every 18 to 24 months is one of the cheapest forms of insurance you can buy on a Wilmington home. Many of our customers in Brunswick Forest schedule it as part of an annual exterior maintenance plan along with gutter cleaning and a window service.
How Often Should You Soft Wash a House in Wilmington?
Most Wilmington homes do well on an 18 to 24 month soft washing cycle. Homes shaded by mature trees, homes on wooded lots, and properties closer to the river or the marshes need it more often, sometimes annually.
Quick rule of thumb based on what we see across the Cape Fear region:
Sunny lot, full exposure, regular gutter cleaning: every 24 months
Average suburban lot in Mayfaire or Pine Valley: every 18 to 24 months
Heavily shaded lot in Landfall or Porters Neck: every 12 to 18 months
Waterfront or marsh-adjacent property: every 12 months
Last spring, we soft washed a two-story home on Bonaventure Drive in Marsh Oaks. The homeowner had not cleaned the exterior in nearly four years and the south wall was still in fair shape, but the north and east walls had black mildew creeping toward the eaves. After a single soft wash visit and a recommendation to switch to an 18-month rotation, those walls have stayed clean and there has been no need to repaint or replace any panels.
The cost of waiting is almost always higher than the cost of staying ahead. A timely soft wash protects your paint, your siding warranty, and the curb appearance of your home in front of every neighbor and every drive-by buyer who passes the house.
Frequently Asked Questions About Soft Washing Cost in Wilmington NC
Will soft washing damage my plants or grass?
No, when done by a professional. Our crew pre-rinses every flower bed, shrub, and grass area with fresh water before we mix the cleaning solution, then re-rinses everything after the wash. The solution is biodegradable and breaks down within hours, and the dilution at runoff is far below any level that would harm plants in Wilmington.
How long does a soft wash last?
A properly performed soft wash will keep mildew and algae off your siding for 18 to 24 months in the Wilmington climate. Homes in shaded areas like Landfall or homes near the Intracoastal Waterway may see new growth begin around 12 to 14 months and benefit from a slightly tighter cleaning schedule.
Can I soft wash my own house?
You can, but the chemistry, equipment, and personal protective gear required are significant. The solution must be diluted within a narrow window to be effective without damaging plants or paint, and a backpack pump or garden sprayer cannot deliver the rinse volume needed to flush the solution properly. Most DIY attempts either underclean (the mildew comes back in months) or overclean (paint and plants get damaged).
How long does a soft wash appointment take?
A typical single-story soft wash for a Wilmington home takes 2 to 3 hours from setup to cleanup. A larger two-story home or a job that includes gutter brightening and driveway washing can run 4 to 5 hours. We will give you a clear time window when we book and a courtesy call before we arrive.
