The three decks Tallahassee actually builds, and why each cleans differently
Walk the back yards of Betton Hills, Killearn Estates, and SouthWood and you will find that a "deck" is really three different surfaces with three different rules. The classic wood deck - pressure-treated pine or cedar, usually built over a raised frame - is the one that suffers most in this climate, because it sits under the oak canopy and stays damp for days after every rain. Composite decking, the gray-and-tan boards that went in on so many homes in the 2010s, does not rot or splinter but still grows a green algae film in the grooves and around the fasteners, and it is far easier to etch than a painter's finish. Then there is the paver patio, concrete or stone set in sand, which takes a firmer hand and carries its own joint-and-weed problem. Reading which of these is actually on your property before the pump runs is what separates a clean that lasts from one that turns a surface gray or strips a coating. We match the pressure and the chemistry to the board or the stone, because the one-size-fits-all wand approach is exactly how a wood deck gets gouged and a composite deck gets hazed.
Magnolia tannin and oak pollen are Tallahassee's deck enemies
The average Tallahassee deck does not get dirty - it gets stained by two local things at once. The live oaks and the big magnolias that shade Centerville, Old Bainbridge, and the canopy roads drip tannin, a brown organic dye that leaches out of the leaves and bark and sets into bare wood within a season, darkening it unevenly and staining a light cedar deck a permanent tea color. On top of that, the spring oak-and-pine pollen load turns every surface a yellow film in March and April, and once humidity grabs it the pollen decomposes into a sticky organic layer that feeds mildew. A deck that is under canopy through February and March can look substantially worse than one in an open yard, even if they were built the same year. This is why a straight power rinse never fixes a Tallahassee deck: the tannin is a dye that has soaked into the wood grain, not a film sitting on top, and it needs a brightening treatment that lifts the stain out of the surface rather than a blast of water that just wets it.
Soft-washing wood without raising the grain
The single most common deck mistake we correct is pressure-washing wood like it was a driveway. Point a high-pressure wand at a pine deck and you do not get a cleaner board - you get the soft grain furred and raised, splinters standing up where the water chewed into the wood, and the surface left rougher and dirtier-looking than before. Older pressure-treated pine, which is what most of the raised decks in Midtown and Indian Head Acres are built from, is the worst for this, because decades of North Florida sun and rain have already worn the surface. We clean wood decks with a soft-wash approach: a detergent solution that kills the algae and mildew at the surface is applied and given time to work, the tannin is lifted with a brightener, and the rinse pressure stays near what a garden hose delivers. The boards come out clean and uniform without the grain raised or the splinters standing up, and on a deck you walk barefoot that difference matters. If the deck is going to be resealed, the clean has to happen first and the wood has to dry completely before anything goes on it - that is the order that makes a sealer actually bond.
Paver patios, joints, and the weeds that live in them
Paver and stone patios are the other half of this job, and they ask for a firmer hand than wood but a careful one around the joints. The concrete and travertine patios common on newer SouthWood and Bradfordville homes collect a slick algae film that gets genuinely dangerous when wet, and the red-clay splash from the beds leaves a rust-orange band along the edges that pressure alone will not shift. Under the oak canopy the joints between the pavers stay damp, and that is exactly where moss roots and weeds germinate - a wand just drives the moss deeper into the sand. We clean paver patios with a flat surface cleaner for an even, stripe-free body, pre-treat the clay staining so it lifts rather than lightens, and then work the joints by hand, raking out the moss and weeds and rinsing the channels clean so the surface reads crisp rather than furry. Where a paver patio keeps losing its joint sand to our heavy rain, the honest follow-up is fresh polymeric sand and paver sealing once the surface is clean and dry, which is what actually keeps the weeds out and the color holding.
Screened decks and the film you cannot see from the house
Much of Tallahassee's outdoor living is screened - the lanais and screened decks off the backs of Killearn and Betton Hills homes where people actually spend the warm evenings. The screen framing and the deck beneath it are where the failure to clean shows up first, because the enclosure traps the humid air and holds it damp long after the open yard dries. The aluminum or vinyl framing dulls with a gray oxidation film, and the deck boards under the screen, protected from rain but not from humidity, grow a fine even coat of algae that looks like dirt from the house and reads clearly as neglect up close. We clean the deck beneath the screen with the same soft-wash method as the rest, then detail the framing so the whole space comes back at once. It is detail work, and it is the difference between a screened deck that looks clean from ten feet and one that actually reads clean underfoot.
When a deck clean lasts longest under the canopy
When you book a deck clean matters almost as much as how it is done, because the live oaks and magnolias that shade most Tallahassee lots shed for a long stretch each winter. The trees hold their leaves through December, then drop them steadily from around February into March, and that leaf drop is followed directly by the year's heaviest pollen. A deck washed in November is not far from being re-buried a few weeks later, when the new litter and tannin land on freshly cleaned boards. In practice we schedule most deck cleans in one of two bands: mid-winter, after the last of the fall debris has come down and before the spring shed picks up, or late spring once the oaks have dropped and pollen has settled. A clean hit in either band holds roughly a year on a shaded lot, and a deck that catches a few hours of afternoon sun stretches longer, since sunlight dries the boards and slows regrowth. If you want the whole exterior handled in one visit, we can pair the deck and patio clean with a house wash; and if you plan to reseal the boards, tell us up front so we schedule the clean to leave the wood fully dry and ready to take a sealer. For every surface we wash around the capital, from siding to driveways to roofs, you can see the complete list on the Tallahassee services page.
