What Wilmington homeowners pay to clean a deck, porch, or patio, why wood and composite price differently, and how coastal humidity drives the cost.
Most residential deck and patio cleanings in the Wilmington area fall in the range of roughly 150 to 450 dollars, with a small wood deck at the low end and a large screened porch, pool deck, and paver patio cleaned together landing higher. A deck is one of the more affordable surfaces to have cleaned, but the number moves with the material, the size, and how much coastal mildew has taken hold. Here is an honest look at what you can expect.
A compact pressure-treated wood deck on a Castle Hayne ranch sits at the low end. A large multi-level deck, a wide brick-paver patio, or a screened porch on a Leland or Landfall home lands higher simply because there is more surface, more railing, and more detail work. Decks that have gone years without cleaning, with a thick green film in the grain, take more time and product and climb above the typical band.
You will sometimes see rock-bottom quotes from crews planning to run a high-pressure wand across the boards. On a Wilmington deck that is a false savings. High pressure furs the wood grain, gouges soft cedar and pine, and blows the joint sand out of a paver patio, so a cleaning becomes a repair or a re-sanding bill. The correct method is a low-pressure soft wash: a cleaning solution kills the mildew and algae at the root, then a gentle rinse lifts it away without ever raising the grain.

No. Cleaning and sealing are two separate jobs. A wash removes the dirt, mildew, and gray weathering; sealing or staining a wood deck afterward protects the boards from Cape Fear sun and moisture and slows the return of growth. Sealing is priced on its own because it uses different materials and needs the wood fully clean and dry first, but a clean deck is exactly what a good stain needs to bond, so many owners book the wash first and the seal a few dry days later.
The biggest saving is to clean before the growth gets severe, since a lightly soiled deck needs far less product than one neglected for years. Bundling the deck with a house wash or driveway in one visit almost always earns a better combined rate, and it means the whole exterior matches when the crew leaves. Because coastal humidity and shade feed mildew year-round here, a regular gentle clean beats an occasional heavy one.
Because so much depends on material, size, and buildup, the surest way to know your exact cost is a quick look or a few photos, which lets us give upfront, flat pricing before any work begins. Get a quote across all of our Wilmington pressure washing services.
Will cleaning damage or splinter my wood deck? Not when done right. We soft wash wood at low pressure with a cleaning solution rather than blasting it, so the grain is never raised or furred and the boards come out clean and even.
Can you clean a composite or screened porch too? Yes. Composite decking and screen enclosures are cleaned with the same gentle soft-wash approach, which clears mildew from the boards, screens, and ceiling without tearing the spline.
How often should a deck be cleaned in Wilmington? Most decks and porches here benefit from a wash every six to twelve months, since shade and coastal humidity grow mildew faster than almost any other part of the property.
