Real deck cleaning prices for the Tallahassee area, plus why wood and composite decks under the canopy oaks need a gentle soft-wash instead of high pressure - and what pushes the number up or down.
A deck is one of the trickiest surfaces to clean on a Tallahassee home. Sitting in the shade of the live oaks, taking constant humidity, and catching every leaf and acorn that drops, wood and composite decks green up with algae and darken with mildew faster than almost anything else on the property. But a deck is not a driveway - clean it wrong and you gouge the boards. So the two questions we hear most are what it costs and how it can be done without wrecking the wood. Here is a straight answer to both.
For a standard residential deck, most jobs in neighborhoods like Killearn, Betton Hills, Southwood, and Midtown land in the 150 to 350 dollar range. A small ground-level platform sits at the low end; a large multi-level deck with rails, stairs, and a screened section climbs from there. Decks are usually quoted alongside the rest of the exterior, so cleaning one on the same visit as a house wash costs less than booking it on its own. These are ranges, not a quote - every deck is different - but they track with the figures in our broader Tallahassee pressure washing cost guide.
Three things set where a deck lands in that range. Size is the obvious one - we clean by the square foot, and railings, spindles, and stairs add surface and hand-work beyond the flat deck floor. The material matters just as much: a pressure-treated pine or cedar deck cleans differently from composite or Trex, and old, weathered wood needs a more careful touch than a newer surface. And the level of buildup is the third factor - a deck on a regular cleaning cycle rinses off fast, while one that has gone years under heavy oak canopy carries deep algae, gray weathering, and tannin staining that take more solution and more dwell time to lift.
This is the part homeowners most need to know before hiring anyone. Concrete can take real pressure; wood cannot. A high-pressure tip run across deck boards raises the grain, splinters the surface, gouges soft summer wood into a washboard texture, and blasts the finish right off - damage that is expensive or impossible to undo. Composite is not safe from it either; too much pressure can permanently mar the cap layer and void the warranty. The correct method is a low-pressure soft-wash: a professional cleaning solution dissolves the mildew, algae, and gray at the root, then a gentle rinse and light, controlled pressure carries it away without tearing up the boards. If a company shows up ready to point a turbo nozzle at your deck, that is a warning sign.
Tallahassee's deep shade gives decks their own set of stubborn marks. Green and black algae take over the shaded, north-facing sections first and grow back fastest. Fallen live-oak and magnolia leaves left sitting on damp boards leave brown tannin stains that soak into the wood and need a chemical treatment, not just a rinse. And any deck that stays perpetually damp under the canopy gets a slick film that is both ugly and a genuine slip hazard. A deck carrying several of these sits at the higher end of the range because it takes real spot work, not just a pass with the wand.
A wash removes the growth, gray, and staining and brings the wood back to a clean, even color; sealing or staining is a separate step that goes on afterward, once the deck is clean and fully dry, to lock in the color and slow the next round of buildup. On a wood deck a fresh seal makes a real difference - it sheds water, resists tannin and mildew, and stretches the interval between cleanings - but it is quoted on top of the cleaning, not baked into it. Composite decks do not get sealed. If you want the deck sealed or re-stained, plan for the wood to dry a day or two after cleaning first.
The fastest way to a firm price is a couple of photos or a quick look at the deck. From there we quote a flat rate with no hidden add-ons, so the number you approve is the number you pay. A deck and patio cleaning in Tallahassee is also cheaper bundled with a house washing on the same visit, since we are already set up on site.
