North Redington Beach sits on one of the narrowest strips of land in Pinellas County — a thin ribbon of sand between the Gulf of Mexico and Boca Ciega Bay, with Gulf Boulevard running the length of it. Homes here take a beating that most inland Florida houses never see: salt aerosol carried on the onshore breeze, near-constant humidity, intense UV, and the wind-driven rain that comes with every named storm that tracks anywhere near Tampa Bay. That combination is hard on building materials, and it's the reason Alpine Exteriors (FL license RB29003900) installs only James Hardie fiber cement siding — never vinyl, never LP SmartSide, never any other engineered wood product. Vinyl softens and warps in sustained coastal heat and can crack in wind-driven debris; engineered wood products rely on resin binders that break down faster in salt-laden humidity. Fiber cement doesn't have those weaknesses, and James Hardie is the manufacturer we trust to back it with a real product warranty in this climate.
This page focuses on the two Hardie siding formats you'll actually choose between on a project here — HardiePlank lap siding and HardiePanel vertical siding — plus the trim and finish decisions that go with each. If you're still deciding whether fiber cement is right for your home in general, this isn't that page; this is the one for homeowners who already know they want Hardie and need to understand panel versus plank.
Both are James Hardie fiber cement, both are rated for our climate zone, and both hold paint or factory finish the same way. But they're engineered for different jobs, and using the wrong one in the wrong spot is a common mistake we see when we're asked to fix or extend siding that another contractor started.
| Factor | HardiePlank (Lap) | HardiePanel (Vertical) |
|---|---|---|
| Orientation | Horizontal boards, each course overlapping the one below | Vertical sheets, typically 4 ft. wide by 8, 9, or 10 ft. tall |
| Classic look | Traditional clapboard, the siding most people picture on a Florida cottage | Board-and-batten or clean modern flat panel |
| Typical use here | Primary siding for the whole house | Accent walls, gable ends, garage faces, porch skirting, mixed-material facades |
| Water shedding | Built-in overlap sheds water course by course | Relies on correct joint treatment, battens, and flashing since there's no natural overlap |
| Install labor | More linear feet of fastening and course alignment | Fewer seams, but each seam and joint needs careful detailing |
HardiePlank is the workhorse. It comes in a range of exposures (the amount of board visible course to course) and edge profiles — smooth or cedar-textured, square-edge or beaded — so we can match anything from a 1950s Florida beach bungalow to a newer elevated build. Most of the older homes on the island were originally sided in wood lap, and HardiePlank is the closest match in profile while being dramatically more resistant to the moisture and pest problems that wood siding eventually runs into this close to the water.
We use HardiePlank as the field siding on the large flat wall areas — the bulk of the house. On barrier island lots, that often means working around narrow side-yard setbacks with limited scaffolding room, tight clearances to neighboring homes, and elevated foundations that change how the bottom course meets the ground. All of that affects the install plan more than it affects the product choice, which is why we walk the site before quoting rather than pricing off a photo.
HardiePanel is the sheet product, installed vertically with battens over the joints (true board-and-batten) or, less often here, with flush-taped and finished seams for a smooth modern look. It's not usually the right choice to cover an entire house in this area — most buyers want the horizontal lap look for the full elevation — but it does specific jobs very well.
Because panel siding has far fewer horizontal laps than plank, correct joint and batten detailing matters more, not less — a poorly flashed panel seam is a direct path for wind-driven rain to reach the wall sheathing. This is a case where the product is simple but the installation isn't, and it's where a lot of the cost difference in workmanship shows up over time.
Trim is the part of a siding job people notice least and regret most when it's done poorly. We use HardieTrim boards — matched fiber cement, not wood or PVC — for:
Matching trim thickness and profile to the siding isn't just cosmetic — mismatched trim creates ledges and gaps where water sits instead of running off, which is exactly the kind of detail that turns into a moisture problem two or three storm seasons later.
| ColorPlus Factory Finish | Primed for Field Paint | |
|---|---|---|
| Application | Baked-on finish applied at the Hardie factory | Primed at the factory, top-coated on site after install |
| Coastal durability | Formulated to resist UV fade and coastal humidity; tends to hold color longer near salt air | Depends heavily on paint quality and prep; may need repainting sooner in direct Gulf exposure |
| Touch-up | Color-matched touch-up product available for nail heads and cut edges | Standard exterior paint touch-up |
| Color choice | Fixed palette of factory colors | Any color, including custom or HOA-matched shades |
| Upfront cost | Slightly higher material cost | Lower material cost, added painting labor |
For most homes directly along Gulf Boulevard, we lean toward ColorPlus because it removes one long-term maintenance variable in an environment that's already hard on painted surfaces. Primed siding is still a solid choice when a specific custom color is non-negotiable or when a home is on the bay side with less direct salt spray.
Standard electro-galvanized nails corrode faster than the siding around them in salt air, leaving rust streaks and eventually losing hold. On every job in North Redington Beach we use stainless steel or hot-dip galvanized fasteners rated for coastal exposure, and the same standard applies to any exposed flashing and hardware.
This stretch of Pinellas County falls under the Florida Building Code's high-wind coastal provisions, which govern fastening schedules, clearances, and the water-resistive barrier behind the siding. We follow Hardie's fastening spec for wind zone rather than the minimum spacing used inland, and we pay close attention to weather-resistive barrier lapping, window and door flashing, and kickout flashing at roof-to-wall intersections — the details that actually keep wind-driven rain out during a tropical system.
Siding installed too close to the ground, a roof line, or a deck surface will wick moisture even in fiber cement. We hold the standard clearances — roughly 6 inches from grade or paved surfaces and 2 inches from roofing — and we seal factory-cut ends before installation, since raw cut edges are the one place fiber cement can take on water if left untreated.
| Factor | Why It Matters Here |
|---|---|
| Access and scaffolding | Narrow side yards, elevated foundations, and close-set neighboring homes can add setup time |
| Plank vs. panel mix | Panel accents with battens add labor per square foot compared to open lap runs |
| Trim volume | Homes with more corners, dormers, and window trim take more HardieTrim and labor |
| Finish choice | ColorPlus vs. field paint shifts cost between material and labor |
| Substrate condition | Older homes may need sheathing repair or added weather-resistive barrier before siding goes on |
| Tear-off scope | Full removal of old siding vs. a partial re-side changes disposal and labor time |
If you're weighing HardiePlank against HardiePanel for a home in North Redington Beach — or trying to figure out how much panel accenting makes sense against a lap-sided elevation — we're glad to walk the property and talk through it. Reach out below for a free, no-pressure estimate.
Yes — fiber cement requires specific blade types for cutting, different fastener specs, and edge-sealing steps that vinyl and wood installers often skip. A crew experienced with general carpentry but not specifically with Hardie products can install it in ways that void the manufacturer warranty.
Confirm their Florida contractor license number, ask specifically what fastener type they use on coastal projects, and ask whether they're a certified James Hardie installer. Also ask how they handle flashing at roof-wall intersections, since that detail matters more here than almost anywhere else.
We've standardized on James Hardie because of its track record in Gulf Coast conditions, consistent product engineering, and manufacturer-backed warranty support. Sourcing one product line also means our crews install it correctly and consistently rather than switching specs between jobs.
James Hardie engineers its siding for specific climate zones, and most of Florida — including North Redington Beach — falls into the HZ10 zone built for high heat, humidity, and storm exposure. We install the HZ10-engineered product line here rather than a generic version meant for drier, milder climates.
It changes the fastener hardware, the fastening schedule for wind resistance, and how closely we manage clearances and flashing, all of which matter more here than on an inland Pinellas County home. Rinsing accumulated salt spray off the siding periodically also helps preserve the finish, whether it's ColorPlus or field paint.
