How Much Does It Cost to Pressure Wash a Deck in Savannah, GA?

Most deck cleaning jobs in the Savannah area run about 150 to 500 dollars, with a small single-level deck near the low end and a large or multi-level deck landing higher, especially when years of Lowcountry mildew have set into the boards. Deck washing is priced by size and material, and in Savannah's humidity and live-oak shade a deck is one of the surfaces that greens up fastest. Here is what actually moves the number.

What is the typical price range?

A compact ground-level deck off the back of a Southside home often cleans for around 150 to 250 dollars, while a larger wraparound or multi-level deck on a Pooler or Wilmington Island property, or an old heart-pine porch downtown, tends to run 300 to 500 dollars or more. Composite decking usually costs a little less than aged wood, because it does not need the same careful, board-by-board attention. A deck neglected for years under oak shade climbs toward the top of the band.

What drives the price in Savannah?

• Size and levels: square footage is the biggest factor, and stairs, railings, and multiple levels all add surface and hand-detail time.
• Material: aged wood must be soft washed carefully to avoid furring the grain; composite and newer pressure-treated boards clean faster.
• How much buildup: a deck coated in years of green algae and black mildew from the shade and humidity needs more solution and dwell time than one cleaned on a schedule.
• Railings and screens: spindle railings and any screened enclosure around the deck are slow, detailed work that adds to the total.

Why should a wood deck be soft washed, not blasted?

It is tempting to hit a gray, mildewed deck with high pressure and watch it turn light again, but that clean look is the machine tearing the soft surface off the wood. Blasting fuzzes the grain, gouges the boards, and can splinter the older heart-pine common on Savannah porches. The right method is a soft wash: a cleaning solution kills the algae and mildew at the root, then a low-pressure rinse carries it away without shredding the wood. It is the same gentle approach we use for deck and patio cleaning in Savannah, and it leaves the boards ready to seal.

Does staining or sealing cost extra?

Yes. Cleaning and sealing are two separate jobs. A wash removes the mildew, algae, and gray weathering; a stain or sealer applied afterward protects the wood and deepens the color, and it will not bond over a dirty deck, so the wash always comes first. Sealing is priced on its own because it uses different materials and needs the boards fully clean and dry. Many Savannah homeowners have the deck cleaned on its own to brighten it, then decide on a finish coat separately.

Frequently asked questions

How often should a deck be cleaned in Savannah? Most decks here do well with a wash every six to twelve months, since shade and humidity grow mildew fast, and shaded or screened decks near the marsh may want it sooner.

Will pressure washing ruin my wood deck? High pressure can, which is why aged wood is soft washed instead. Done at low pressure with the right solution, cleaning brightens the boards without harming them.

Can you clean a composite or Trex deck? Yes. Composite decking still grows mildew and collects pollen in the Lowcountry, and it cleans gently and quickly. Get an upfront quote for your Savannah deck and we will price it flat.
