Deck Cleaning Naples FL —
Wood & Composite Decks
Most Naples outdoor floors are pavers, but raised and waterfront homes often have wood or composite decks that grow mold fast in our humidity. We clean them with low pressure and the right cleaner for each material, and quote online.

Wood and composite decks show up on stilt homes in flood zones, older cottages near the beach, homes on Marco Island and the Isles of Capri, and second-floor balconies on raised builds. They also show up around hot tubs and outdoor kitchens. They are less common than pavers here, so a lot of crews treat them like concrete. That is how decks get damaged.
Our climate keeps decks damp. Morning dew, summer rain and shade from screen enclosures or palms let green algae and black mildew settle into the wood grain and the textured surface of composite boards. The growth turns slick quickly. On a raised deck with stairs, that is a fall risk.
Pressure-treated pine is soft. Too much pressure lifts the fibers and leaves a fuzzy, splintered surface that soaks up the next round of dirt even faster. Composite boards can show permanent wand marks, and many composite makers warn against high pressure in their care guides.
Salt air adds a fine film to decks within a few blocks of the Gulf and on canal homes. Rusty fasteners and metal furniture leave dark stains in the wood. Tannins bleed out of the boards and turn gray-brown after rain. Each of these needs its own cleaner.

Tell us when you book. We will clean and brighten the wood so it is ready, and let you know how many dry days it needs before your stain or sealer goes on.

For wood, we apply an oxygen-based wood cleaner (sodium percarbonate) that lifts graying, dirt and mildew without the harsh bleaching that chlorine causes on bare wood. After dwell time we rinse with low pressure, moving with the grain using a wide fan tip.
We follow wood cleaning with an oxalic acid brightener. It neutralizes the cleaner, lifts tannin and iron stains, and brings back the board color. Wood that has been brightened takes stain more evenly.
Composite gets a gentler routine. We use a mild soft wash solution to kill mold in the embossed grain, scrub with soft brushes, and rinse at low pressure. We also clear the gaps between boards, where leaves and dirt hold moisture and feed mold from underneath.
On any deck we check for loose boards, popped screws and soft spots while we work, and point them out to you. We do not do carpentry, but you will know what needs attention.
| Deck Material | Common Problem | Cleaner | Pressure |
|---|---|---|---|
| Pressure-treated pine | Gray weathering, mildew | Oxygen cleaner + oxalic brightener | Low, fan tip |
| Cedar or tropical hardwood | Tannin bleed, dark water spots | Oxygen cleaner + brightener | Very low |
| Capped composite | Mold in the grain, pollen film | Mild soft wash + brush | Low |
| Older uncapped composite | Deep mold spots, fading | Soft wash, longer dwell | Low |
| Painted or stained wood | Peeling, mildew on coating | Mild detergent | Low; no stripping |
Raised living decks
Homes built above flood elevation often have wide decks and long stairs. We clean treads carefully and keep runoff off the parking area below.
Canal and bay homes
Salt film and bird droppings build up fast. We keep chemical use low near the water and rinse thoroughly.
Second-floor wood decks
We protect the siding and windows below and work from the deck surface with low-pressure equipment.
Hot tubs and outdoor grills
Grease from grills and body oils around spas need a degreaser before the mold treatment.
Decks vary a lot in size, height, stairs and material, so we quote each one. Many owners pair deck cleaning with a house wash or lanai cleaning in the same visit.
Railings, spindles and stair stringers are part of the deck price. They hold mildew in the corners, so we brush them by hand.
Identify the material
We confirm whether the boards are wood, capped composite or older composite and check for existing stain or paint.
Clear and protect
Furniture comes off, plants below are wetted, and we cover outlets and light fixtures near the deck.
Apply the right cleaner
Oxygen cleaner for wood, mild soft wash for composite, degreaser first on grill and spa areas.
Brush and low-pressure rinse
We scrub corners, rails and gaps, then rinse along the grain with a wide fan tip.
Brighten wood
Wood decks get an oxalic brightener to even out color and remove tannin and rust marks.
Walk-through
We point out any loose boards or fasteners and leave a written record of what was cleaned and how.
