A deck in Cork isn't just an outdoor living space — it's a structure that has to survive Gulf humidity, salt-tinged air if you're anywhere near the intracoastal, afternoon thunderstorms that roll in almost daily through summer, and the occasional direct hit from a tropical system. We build and repair decks with all of that in mind from the first design conversation, not as an afterthought once the framing is up. Whether your lot sits closer to the water or further inland toward the older neighborhoods, the fasteners, footings, and board selection we recommend account for what our specific stretch of Florida actually does to a wood or composite structure year-round.
We are Alpine Exteriors, FL license RB29003900. Deck work is one piece of a broader exterior construction practice, and we approach it the same way we approach roofing or siding: build it right the first time so you're not calling someone back out in three years.
This is the first real fork in the road for almost every deck project, and the right answer depends on your budget, how much upkeep you want to do, and how long you plan to stay in the house.
Modern capped composite boards (the kind with a fused polymer shell around a wood-plastic core) are built to resist moisture absorption, which matters a lot in a climate where the air itself carries humidity most of the year. They don't need staining or sealing, they resist the mildew bloom that shows up on wood decking in shaded, humid corners of a yard, and they hold their color better under intense Florida UV than most people expect once they've seen a few seasons pass. The tradeoff is upfront cost — composite runs higher per square foot than pressure-treated lumber — and the material does get hot underfoot in direct summer sun, something to think about if your deck faces west or south with no shade structure.
Pressure-treated pine is still the most affordable option and, done correctly with proper flashing and fastening, performs well. Cedar and tropical hardwoods like ipe cost more but resist rot and insects better than treated pine. The catch in our climate is maintenance: wood decking here needs sealing on a real schedule — we tell homeowners every 1-2 years depending on sun and moisture exposure — or you'll see graying, splitting, and eventually soft spots at fastener locations. Skipped maintenance is the single biggest reason we get called out to repair wood decks that are otherwise structurally young.
| Factor | Composite | Wood (Treated Pine) |
|---|---|---|
| Upfront cost | Higher | Lower |
| Maintenance | Occasional wash | Sealing every 1-2 years |
| Humidity/moisture resistance | High | Moderate, maintenance-dependent |
| Surface heat in direct sun | Can run hot | Cooler underfoot |
| Expected lifespan (properly built) | 25-30+ years | 15-20 years with upkeep |
Most deck failures we're called to look at in this area aren't a bad board here or there — they're fastener corrosion or a framing detail that let water sit where it shouldn't. A few things we build into every deck regardless of decking material:
Deck construction in Florida almost always requires a building permit once you're above a certain height or attached to the structure, and it should go through a wind-load review given our storm exposure. We handle the permitting process as part of the project — pulling the permit, scheduling inspections, and building to the version of the Florida Building Code that's currently in effect for our wind zone. Skipping the permit step might save a little time upfront, but it creates real problems at resale, since unpermitted structural work is exactly the kind of thing a home inspector flags and a buyer's lender can require corrected before closing.
A deck design conversation in this climate is different than it would be somewhere with a shorter outdoor season. A few things worth thinking through before we finalize a layout:
Given how much of the year is warm here, orientation matters. A west-facing deck with no shade structure will see brutal late-afternoon sun most of the year. Pergolas, shade sails, or simply positioning the deck to take advantage of existing tree cover can make the difference between a space you use daily and one that sits empty from May through September.
Florida's heavy summer rain means water has to have somewhere to go. We grade and, where needed, install drainage systems underneath raised decks so the space below doesn't turn into standing water after every afternoon storm — important both for the deck's own longevity and for anything you plan to store or use underneath it.
Railing height and baluster spacing are code-driven, not optional, once your deck surface is a certain height off grade. We build to code as a floor, then work with you on railing style — cable, aluminum, composite, or traditional wood baluster — based on the look you want and the maintenance you're willing to take on.
Not every deck call is new construction. We inspect existing decks for the things that actually matter structurally: soft or spongy decking (usually moisture intrusion), rust streaking at fastener heads (a sign of fastener corrosion, not just cosmetic), ledger board separation from the house, and post-to-footing connections that have shifted. Sometimes a deck needs new decking boards on a sound frame. Sometimes the frame itself is compromised and a rebuild is the honest recommendation — we'll tell you which one it is rather than selling you the bigger job by default.
A deck attaches directly to your home's structure and sits exposed to the same weather that tests a roof or a wall system. We don't treat it as a separate, lower-stakes category of work. The same attention we put into flashing details on a siding job or fastener patterns on a roof carries over to how we frame and finish a deck — because in this climate, the details are what separate a deck that's still solid in fifteen years from one that's soft underfoot in five.

Permitting timelines vary by scope, but once a permit is issued, most residential deck builds take one to three weeks depending on size and material. We build the permit and inspection schedule into your project timeline upfront so there aren't surprises.
Ask to see their license and proof of insurance, ask specifically what fastener and flashing materials they use (not just the decking brand), and ask how they handle the permitting and inspection process. A contractor who can answer fastener and framing questions in detail, not just decking color options, is usually the one who understands how decks fail in Florida.
No — composite boards vary in how they're capped, how they handle moisture at cut ends, and how their warranties are structured. We can walk you through the options that hold up well in Gulf Coast humidity versus ones better suited to drier climates.
It depends on height and attachment — many low, freestanding platform decks fall under different permit thresholds than a raised deck attached to the house. We check the specifics for your project against current Florida Building Code requirements before we start.
Yes — we use corrosion-resistant structural hardware and proper hurricane tie connections at posts and beams regardless of whether we're building in composite or wood, since wind uplift and humidity are constants here, not occasional concerns.
