What's the actual difference between a deck and a screened lanai, and does it change how it's built?

A deck is an open, unenclosed structure, while a lanai adds a screen enclosure on top of a deck or slab. The framing and footing requirements for the deck portion are largely the same either way, but adding a screen enclosure brings its own permit and wind-load requirements for the enclosure structure itself. If you're weighing both options, it's worth deciding early since it affects the footing layout and post placement.

What should I actually check before hiring someone to build a deck in St. Petersburg?

Confirm they're licensed to do contracting work in Florida and carry liability insurance, and ask whether they pull their own permits with the city rather than having you do it. Ask to see how they detail the ledger board attachment and flashing specifically, since that's the connection most likely to cause problems later if it's done poorly. A contractor who can explain their process clearly, without hand-waving, is usually a good sign.

Should I go with composite decking like Trex or TimberTech, or stick with wood?

Composite costs more upfront but needs far less maintenance and holds up longer under our UV exposure and humidity, while wood is cheaper initially but requires regular sealing to avoid graying and moisture damage. Tropical hardwoods split the difference — higher cost, very durable, moderate upkeep. The right choice depends on your budget and how much maintenance you actually want to do over the deck's lifespan.

Why does the type of fastener and hardware matter so much on a Florida deck?

Standard fasteners and joist hangers can corrode within a few years in our salt air and humidity, which weakens connections long before the wood or decking itself fails. We use stainless steel or hot-dip galvanized hardware rated for coastal exposure throughout the structure, including at the ledger, posts, and joist hangers. It costs more than uncoated hardware, but it's the difference between a deck that stays structurally sound and one that develops hidden weak points.

Does Crescent Lake's tree canopy affect how a deck should be built or maintained?

Yes — heavy shade from mature trees keeps deck surfaces damp longer after rain, which increases the risk of mildew and, for wood decking, rot if the boards aren't properly spaced for airflow and drainage. We account for that in the framing layout and board spacing, and homeowners under heavy canopy should expect to clean leaf debris from the deck surface more often than an open, sunny lot would require.

Custom Decks in Crescent Lake, St. Petersburg | St. Petersburg Siding Company

Decks Built for Crescent Lake, Not Just Any Yard

Crescent Lake is one of St. Petersburg's older, established neighborhoods — mature tree canopy, a mix of bungalow and mid-century homes, and lots that were laid out decades before anyone was thinking about hurricane wind ratings or composite decking. A lot of the outdoor living space on these properties is original to the house or was added piecemeal over the years, which means when a homeowner here calls about a custom deck, we're usually not just building a platform — we're figuring out how it ties into an older home's framing, drainage, and exterior finish.

We're a siding and exteriors contractor based in Pinellas County, and decks are part of that same conversation. A deck that's bolted into the side of your house is a penetration into your home's exterior envelope, and how that connection is flashed and sealed matters just as much as how the deck itself is framed. That's the lens we build through — not just "will this deck hold weight," but "will this deck protect the house it's attached to."

What Florida's Climate Actually Does to a Deck

St. Petersburg decks take a beating that decks in most of the country never see. It's not one thing — it's four things happening at once, year-round.

Sun and UV

Florida gets some of the most intense, most consistent UV exposure in the continental U.S. On an uncovered deck, that means wood fibers break down and gray out faster than the manufacturer's brochure suggests, and even "fade-resistant" composite boards will lose some color depth over the years. UV is also what dries out and cracks sealants and finishes long before the structure itself is a problem.

Wind-Driven Rain and Humidity

Afternoon storms here don't just fall straight down — wind-driven rain gets pushed sideways into ledger connections, under railings, and into any gap that isn't properly flashed or gapped for drainage. Combine that with our humidity and you get a structure that's almost never fully dry, which is exactly the condition that causes rot in wood framing and corrosion in hardware that isn't rated for it.

Hurricane-Force Wind

Pinellas County sits in a high-wind design zone, and a deck is a lateral and uplift load on your house whether it's attached or freestanding. Railings, guardrail posts, and the ledger connection all need to be engineered to resist wind forces, not just gravity loads — a deck that would pass inspection in a low-wind-zone state can fail here.

Salt Air

St. Petersburg sits between the bay and the Gulf, and salt-laden air travels further inland than most people expect. It accelerates corrosion in fasteners, joist hangers, and railing hardware that isn't specified for coastal exposure — this is one of the most common reasons we see decks develop rust streaks and loosening hardware years before the wood itself is a problem.

Permits, Wind Load, and Inspections in St. Petersburg

Custom decks in the City of St. Petersburg require a building permit, and that's not paperwork for its own sake — it's what forces a design to actually account for our wind zone, soil conditions, and attachment method instead of guessing. A code-compliant deck package generally covers:

Engineered or code-prescriptive framing sized for the deck's span, height, and use
Footing depth and bearing sized for local soil conditions, not just a "dig a hole and pour" approach
A properly through-bolted (not just lag-screwed) ledger connection with flashing that sheds water away from the house's wall assembly
Guardrails and stair railings meeting current height and baluster-spacing requirements
Hardware — joist hangers, post bases, hurricane ties — rated for the load path and corrosion exposure

Inspections typically happen at the footing stage and again at final, and a Pinellas County-based crew that pulls permits in this jurisdiction regularly knows what the inspectors are actually looking for on each pass, which keeps a project from stalling out waiting on a re-inspection.

Choosing Deck Materials for a Coastal Florida Climate

There's no single "best" decking material — it's a trade-off between upfront cost, ongoing maintenance, and how the surface behaves in our sun and humidity. Here's how the common options actually compare in this climate.

Material	Upfront Cost	Maintenance	Sun & Heat Behavior	Realistic Lifespan Here
Pressure-treated pine	Lowest	Needs re-sealing every 1-2 years to resist UV graying and moisture	Can get hot underfoot; prone to splintering as it ages	10-15 years with consistent upkeep
Capped composite (e.g. Trex, TimberTech)	Mid to high	Low — periodic washing, no sealing or staining	Darker colors run hotter underfoot in direct sun; fade is slow but not zero	25+ years, backed by manufacturer warranty
Tropical hardwood (e.g. ipe)	Highest	Moderate — oiling recommended to maintain color, though it will gray naturally if skipped	Very stable, dense, holds up well to sun and moisture	25-40 years with reasonable care

We install all three. Where we push back is on cutting corners in the framing or fasteners to make a composite deck cheaper — the surface material is only as good as what's holding it up, and in this climate, undersized or non-rated hardware is the actual weak point far more often than the decking itself.

Design Choices That Make Sense in a Neighborhood Like Crescent Lake

A few things come up repeatedly on Crescent Lake properties that are worth planning for up front:

Tree Canopy and Drainage

Mature oak canopy is one of the best things about this neighborhood, and it also means more leaf litter and shade landing on your deck. Shade reduces UV stress on the boards, but it also means the deck surface stays damp longer after rain. We space and gap boards for airflow and drainage specifically because a shaded deck that can't dry out is more prone to mildew and, in wood, rot.

Matching an Older Home's Character

Many homes in this part of St. Petersburg have a distinct architectural character — deep eaves, particular trim details, established landscaping. Railing style, post spacing, and skirting can either blend into that or fight it, and we design to match rather than default to whatever's easiest to build.

Tying Into the Exterior Envelope

Because we do siding work as our core trade, we pay particular attention to what happens where the deck ledger meets the house — proper flashing integration with your existing siding or wall covering is what keeps that connection from becoming a hidden moisture path into your wall framing over time.

How We Build a Deck to Last in This Climate

Our process is the same discipline we bring to siding, applied to decks:

Site evaluation — we look at drainage, sun exposure, soil, and how the deck will attach to your existing structure before we design anything.
Design and engineering — permit-ready drawings sized for St. Petersburg's wind and load requirements, not a generic template.
Material walkthrough — an honest conversation about wood versus composite versus hardwood for your budget and how much upkeep you actually want to do.
Permitting — we handle the submission and inspection scheduling with the city.
Construction — footings to spec, a properly flashed and through-bolted ledger, and stainless steel or hot-dip galvanized fasteners and hardware throughout to handle salt air and humidity.
Final walkthrough — we cover what maintenance the specific material you chose actually needs, in plain terms.

Maintaining a Deck in Pinellas County's Climate

Whatever material you choose, a little regular attention goes a long way here. A practical maintenance checklist:

Sweep leaf litter and debris out from between boards regularly, especially under tree canopy
Check railing posts and stair connections for looseness once or twice a year
Look for rust streaking at fastener heads — an early sign hardware isn't holding up to salt exposure
Re-seal or oil wood decking on the schedule the product actually calls for, not "when it looks bad"
Wash composite and hardwood decking periodically to prevent mildew buildup in shaded, humid spots
Inspect the ledger board area at the house wall annually for any signs of water staining or soft wood

Why a Crew That Already Works This Neighborhood Matters

Older homes in established neighborhoods like Crescent Lake often have quirks — framing that's not perfectly square, siding materials that are no longer commonly stocked, lots with mature trees that constrain access and staging. A crew that's already worked houses like yours in this part of St. Petersburg isn't guessing at those problems for the first time on your project. We also know the rhythm of building here: scheduling exterior work around Florida's wet season and hurricane season, and working efficiently with the city's permitting and inspection process because we do it regularly, not occasionally.
