Deck cleaning on the Grand Strand typically runs $150-$400. What drives the price, how size and decking material change it, and when sealing is worth adding.
Pressure washing a deck in Myrtle Beach typically costs $150 to $400 for a standard residential deck, which works out to roughly $0.75 to $2.00 per square foot. A small 200-square-foot deck usually lands near the bottom of that range, while a large multi-level deck with railings, stairs, and a screened section can run $400 to $600. Adding a stain or sealer afterward is a separate job that generally doubles the total.
Square footage sets the starting number, but the Grand Strand adds its own variables. The things that move a quote most:
Rough ranges for a typical Myrtle Beach deck, cleaning only:
Most quotes on the Strand are flat-priced after a look at the deck rather than billed by the hour, so you know the number before anyone starts.
It changes the method more than the price, though method drives time. Pressure-treated pine, the most common decking on Grand Strand homes, is soft and takes a controlled low-pressure clean so the grain does not fuzz up. Composite boards clean easily but need low pressure to avoid marring the cap. Older hardwood and painted decks want the gentlest approach of all. On any of these, a soft wash that lets a cleaning solution break down the mildew works better than force, because the humidity here drives growth into the wood rather than leaving it sitting on top.
If the deck is bare wood, sealing is what makes the cleaning last. Coastal sun and salt are hard on exposed boards, and a sealer applied after the deck dries fully, typically two or three days, keeps water and UV out of the grain. Expect sealing to cost roughly what the cleaning did, sometimes more on a large deck. Composite decking does not need it. If your budget only covers one thing this year, clean it, because sealing over trapped mildew locks the problem in.
You can, and it is where a lot of decks get damaged. A rented machine at full pressure will carve visible lines into pine, splinter the surface, and leave stripes you cannot sand out easily. If you do it yourself, use the widest tip, keep the wand well back and moving, and test in a corner first. The honest tradeoff: a rental runs $50 to $90 for a day, so on a small deck you are saving perhaps a hundred dollars against the risk of permanently marking the boards.

How often should a deck be washed on the Grand Strand? Once a year suits most decks here. The humidity and shade keep mildew working year-round, and an annual wash before the season means the space is ready when you actually want to sit on it.
Will pressure washing strip my deck's stain? It can, and sometimes that is the point. A worn stain will lift unevenly under cleaning, so if yours is failing, plan on a re-stain afterward rather than expecting the old finish to survive.
How long does a deck cleaning take? Most single-level decks are done in one to three hours. Add time for heavy railings or a screened porch. You can use the deck once it dries, though sealing means waiting a couple of days first. For a flat price on yours, see our Myrtle Beach pressure washing services.
