Two Different Hardie Products, Two Different Jobs

When people say "Hardie board," they usually mean one thing, but James Hardie actually makes two distinct fiber cement siding profiles that solve different problems on a Redington Beach home: HardiePlank lap siding and HardiePanel vertical siding. We install both, and the choice isn't just cosmetic — it affects how the wall handles wind-driven rain off the Gulf, how trim details get built, and how the house reads from the street. This page is about that decision, not a general "why fiber cement" pitch. If you already know you want James Hardie and just need to understand plank versus panel, trim options, and finish choices for a barrier island home, you're in the right place.

We install James Hardie fiber cement exclusively. We don't offer vinyl, LP SmartSide, or engineered wood siding, and we won't quote them. That's a standard we hold across every job, not a knock on any specific competitor's product — it's about what we're confident standing behind on a Pinellas County barrier island with full-time salt exposure and an active hurricane season every year.

HardiePlank: The Lap Siding Most Redington Beach Homes Already Wear

HardiePlank is the horizontal lap board most people picture when they think "siding." Each board overlaps the one below it, shedding water down and out the way clapboard has for a century, but built from fiber cement instead of wood. It's the right call for the majority of homes here — classic beach cottages, ranch-style houses on the inland side of Gulf Boulevard, and two-story rebuilds that want a traditional look.

Plank Profiles and Exposure

HardiePlank comes in a few reveal widths — most commonly 5.25" and 7", though other exposures are available — and in smooth or cedar-textured finishes. Wider exposures show fewer shadow lines and read as more modern; narrower exposures give a tighter, more traditional cottage look. We help you pick exposure based on the scale of the house, not just personal taste — a wide reveal can look thin and flat on a two-story wall, while a narrow reveal on a small single-story home can look busy.

Where Plank Makes Sense

HardiePanel: Vertical Siding for a Different Character

HardiePanel is a large-format vertical sheet product, typically installed with battens over the seams (board-and-batten) or as a smooth or textured panel with trim at the joints. It's less common than plank on older Redington Beach streets, but we're seeing more of it on newer builds, additions, and accent walls — especially on beach houses going for a more contemporary or "elevated coastal" look, or on homes that want to visually break up a tall Gulf-facing elevation.

Panel Applications

Full board-and-batten fronts are one option, but panel is just as often used selectively — a vertical accent on a gable end, a porch surround, or a garage face paired with horizontal plank on the rest of the house. That mixed approach is common on Redington Beach remodels where the owner wants to modernize the front elevation without re-siding the entire structure.

Installation Differences That Matter

Panel siding installs differently than plank — larger sheets, different fastening patterns, and battens or trim pieces that have to be flashed correctly at every vertical seam. On a wall exposed to sideways rain off the Gulf, sloppy batten flashing is exactly where leaks start. This is a case where installer experience with the specific product matters as much as the product itself; panel siding done wrong fails faster than plank done wrong, because there's more seam length per square foot of wall.

Trim: Where Fiber Cement Siding Actually Gets Protected

Trim isn't decoration — it's the flashing and transition system that keeps water out at every window, door, corner, and roofline. James Hardie's trim boards (HardieTrim) come in smooth and textured finishes and get used at outside corners, window and door casing, frieze boards under the roofline, and water table boards at the base of the wall.

On Redington Beach homes we pay particular attention to a few trim details:

Good trim work is honestly what separates a siding job that looks sharp for twenty years from one that starts showing caulk failure and water staining in three.

Finish Options: Factory-Primed vs. ColorPlus

James Hardie offers two finish paths, and the choice affects both appearance and long-term maintenance.

ColorPlus Prefinished

ColorPlus siding comes from the factory with a baked-on, color-matched finish system applied under controlled conditions, with color-matched caulk and touch-up available. On a Gulf-facing home, this matters — factory-applied finishes hold color and resist fade from constant UV and salt air better than most field-applied paint, and they typically carry their own finish warranty separate from the substrate warranty.

Primed for Field Painting

Primed siding gives you full control over paint color and lets you use a local painter of your choice, or match an exact custom color that isn't in the ColorPlus palette. The trade-off is that field-applied paint on a coastal home needs more frequent attention than a factory finish, particularly on Gulf-facing elevations that take the brunt of salt spray and afternoon sun.

We'll walk you through both during the estimate — for most Redington Beach re-sides, ColorPlus ends up being the lower-hassle long-term choice, but there are good reasons to go primed, especially if you're matching an existing paint color on the house or a shared building.

Why This Matters Specifically on a Barrier Island

Redington Beach sits on a narrow strip of Pinellas County between the Intracoastal Waterway and the Gulf of Mexico, which means every house here deals with constant salt-laden air, high humidity, and direct exposure during hurricane season from June through November. Whether a home sits right off Gulf Boulevard or a block back on the bay side, wind-driven rain and salt spray reach the siding differently depending on orientation, and that affects real decisions: which elevations get panel versus plank, how tight the trim and flashing details need to be, and whether ColorPlus finish is worth the upgrade over primed-and-painted. Fiber cement doesn't rot, doesn't attract termites, and holds up to salt exposure in a way that wood-based products struggle with over time — that's the core reason we only install James Hardie here.

What the Install Process Looks Like

Every Redington Beach siding job starts with an on-site assessment of the existing wall assembly — checking for moisture damage behind old siding, evaluating the sheathing, and confirming what's actually holding up the current cladding before anything comes off. From there:

  1. Removal of old siding and inspection/repair of sheathing and house wrap
  2. Installation of a code-compliant weather-resistive barrier
  3. Hanging of HardiePlank or HardiePanel per Hardie's fastening and clearance specifications
  4. Trim, corner, and flashing installation at every penetration and transition
  5. Finish work — either ColorPlus touch-up or full field painting if primed siding was used

We follow James Hardie's published installation instructions, including minimum ground clearance and fastener spacing, because that's what keeps the manufacturer's warranty intact — cutting corners on install details is the fastest way to void coverage on an otherwise excellent product.

Get a Straight Answer on Panel vs. Plank for Your Home

Every Redington Beach lot is a little different — lot orientation, how close you sit to the Gulf, what your neighbors' homes look like, and what you're trying to achieve with the remodel all factor into whether plank, panel, or a mix of both is the right call.

Frequently Asked Questions

What's the actual difference between HardiePlank and HardiePanel?

HardiePlank is horizontal lap siding that overlaps board over board, while HardiePanel is a large vertical sheet product often installed with battens for a board-and-batten look. Plank is the more traditional choice; panel is used for a more modern or accent look, often mixed with plank on the same house.

How do I check that a siding contractor is actually licensed to work in Florida?

You can look up any contractor's license status directly on the Florida DBPR website using their license number. Alpine Exteriors holds FL license RB29003900 — ask any contractor for their license number before signing anything, and confirm it's active and in good standing.

Why do you only install James Hardie and not other fiber cement brands?

We've standardized on James Hardie because of its track record, product consistency, and the strength of its installation documentation and warranty structure. Sticking with one manufacturer also means our crews are deeply familiar with its specific fastening, clearance, and flashing requirements rather than switching specs between brands.

Can I mix HardiePanel and HardiePlank on the same house?

Yes, it's a common approach — using vertical panel as an accent on a gable end, porch, or garage face while keeping horizontal plank on the main body of the house. It's a good way to add visual interest without a full re-side.

Does living on a barrier island like Redington Beach change how siding should be installed?

Yes — homes here face constant salt air and direct exposure during hurricane season, so flashing details, fastener choices, and finish selection matter more than they would further inland. We build trim and seam details with that exposure in mind rather than using a generic inland installation approach.
