Indian Shores sits on one of the narrowest strips of land in Pinellas County, with the Gulf of Mexico on one side and the Intracoastal Waterway on the other. Almost every home here deals with salt-laden air, wind-driven rain, and the kind of humidity that never really lets up between April and October. That combination is hard on siding. It's especially hard on siding that isn't built for it. We install HardiePlank lap siding — James Hardie's fiber cement lap product — because it's engineered to hold up to exactly this kind of exposure without the moisture problems, insect vulnerability, or repeated repainting that come with other materials. This page is about HardiePlank specifically: the plank profiles, exposure widths, the board-and-batten alternative, ColorPlus factory finish, and the installation details that actually determine how a job performs on a barrier island property.
"HardiePlank" isn't one product — it's a family of lap siding profiles, and the profile you choose changes both the look of the house and how the installation is detailed.
Cedarmill has a subtle woodgrain texture pressed into the face, which reads as traditional lap siding from the street and does a good job hiding minor surface imperfections. Smooth has a clean, flat face that suits more modern or coastal-contemporary homes — a look we see more of on newer builds and remodels along the Gulf side of the island. Neither performs differently in terms of moisture resistance; the choice is purely aesthetic, and we walk homeowners through both in person before ordering material.
Exposure is the amount of each plank left visible after the next course overlaps it. A 4" exposure gives a tighter, more traditional shadow line with more boards per wall — more material, more fasteners, more labor. A 7" exposure shows fewer, wider courses for a bolder, more contemporary look and installs faster. Most Indian Shores homes we work on land in the 5"–7" range depending on the era and style of the house; older Florida cottages tend to look right with a narrower reveal, while newer construction and larger elevations often carry a wider exposure well. Exposure width also affects fastener spacing and how many courses run past window and door trim, so it's one of the first things we lock down during measurement — not something to decide after material is on site.
James Hardie also makes a board-and-batten panel product, and we get asked regularly which one fits a given house better. Both are fiber cement and both carry the same core durability, but the look, the framing behind them, and the maintenance profile differ.
| Factor | HardiePlank Lap Siding | Board-and-Batten |
|---|---|---|
| Look | Horizontal shadow lines, classic to coastal-traditional | Vertical panels with raised battens, farmhouse or modern coastal |
| Best fit | Full elevations, most home styles | Accent walls, gables, porch entries, or full vertical siding on newer builds |
| Water shedding | Overlapping courses shed water downward by design | Relies more heavily on correct flashing behind battens and at panel seams |
| Installation labor | More courses and fasteners on tall walls | Fewer seams horizontally, but batten strips add fastening steps |
| Common use here | Whole-house siding, most common choice islandwide | Paired with lap siding as an accent, or used on garages and gables |
On Indian Shores we most often use board-and-batten as an accent — a gable end, a porch surround, a garage face — paired with HardiePlank lap on the rest of the house. It reads well against the beach-town architecture without turning the whole exterior vertical, which can look busy on smaller lots.
Every board we install can be ordered in James Hardie's ColorPlus finish — a multi-coat color baked onto the fiber cement at the factory under controlled conditions, rather than field-painted after installation. For a barrier island house, that difference matters more than it might inland. Field-applied paint on lap siding is only as good as the weather conditions on the day it's sprayed and the prep work underneath it; ColorPlus color is cured in a controlled environment before the boards ever reach the truck, which gives more consistent coverage and better fade resistance against constant UV and salt exposure. ColorPlus also comes with Hardie's finish warranty separate from the product warranty, and touch-up paint is color-matched and available for the occasional ding from lawn equipment or storm debris. We still offer primed boards for homeowners who want a specific custom color mixed locally, but for most Indian Shores projects we steer people toward ColorPlus specifically because of the salt air.
HardiePlank is a good product, but a good product installed loosely will still fail early in this climate. The details below are where we spend the extra time.
Every plank gets fastened per Hardie's published nailing pattern for the exposure and wind exposure category of the home — not a generic pattern reused from a less exposed jobsite. Corrosion-resistant fasteners are non-negotiable this close to the Gulf; standard fasteners will rust and stain the face of the siding within a couple of seasons.
Behind every course of HardiePlank there's a water-resistive barrier, and at every window, door, and penetration there's flashing designed to direct water back out rather than behind the siding. On homes with stucco or older siding underneath, we check and often replace the underlying barrier rather than lapping new siding over questionable house wrap — skipping that step is the single most common cause of hidden rot we find when we tear off older siding on the island.
Hardie specifies minimum clearances between the bottom of the siding and grade, roofing, decks, and other horizontal surfaces. On canal-front and Gulf-side lots where landscaping beds sit high against the foundation, we hold those clearances even when it means adjusting grade or trim rather than letting the siding sit too close to standing water or irrigation spray.
Fiber cement doesn't absorb water the way wood-based sidings do, and it isn't a food source for termites or wood-boring insects, which matters in a county where both are a fact of life. It also doesn't warp or buckle from humidity swings the way engineered wood panels can. That said, no siding is maintenance-free. We tell every Indian Shores homeowner the same short list: rinse salt spray off the exterior periodically, keep caulking at trim and penetrations in good condition, and have the exterior looked at after any named storm that brought sustained wind or wind-driven debris to the island. HardiePlank holds up well through hurricane season, but a quick post-storm check catches loose trim or minor flashing damage before it becomes a bigger repair.
Every Indian Shores home is different, but the line items that move the price are consistent. We go over all of these during the estimate walkthrough so there are no surprises once material is ordered.
| Factor | How It Affects Cost |
|---|---|
| Tear-off vs. new construction | Removing and disposing of existing siding adds labor and dump fees |
| Underlying wall condition | Rotted sheathing or old barrier that needs replacing adds material and time |
| Exposure width chosen | Narrower exposure means more boards and fasteners per elevation |
| Lap vs. board-and-batten mix | Batten accents add trim and fastening steps beyond straight lap runs |
| ColorPlus vs. primed/field-painted | ColorPlus adds material cost but removes a separate paint job |
| House height and access | Multi-story or tight-lot homes need more scaffolding and staging time |
If your Indian Shores home needs new siding — whether it's a full tear-off after storm damage, an update to a home that's still wearing its original exterior, or a board-and-batten accent to change up the look — we're glad to walk the property with you and put together a straightforward, no-pressure estimate. Use the form below to get started.
Fiber cement is heavier and rigid, so it's face-nailed directly to the wall in overlapping courses rather than hung loosely on a track like vinyl. It also requires cutting with fiber-cement-rated blades and careful fastener placement, since improper nailing can crack the board or void the manufacturer's warranty.
Confirm the contractor holds an active Florida license — ours is RB29003900 — and ask specifically whether they're a manufacturer-recognized installer for the siding brand you're considering. Also ask how they handle wall inspection and flashing once old siding is removed, since that hidden work matters more than the visible finish.
We standardized on James Hardie because it holds up to Gulf Coast humidity, salt air, and storm exposure better than vinyl, which can warp and fade, or engineered wood, which is more vulnerable to moisture over time. Installing one product line well lets us know its details cold rather than spreading expertise thin across several systems.
James Hardie engineers certain products in two formulations for different climate zones — HZ5 for areas with freeze-thaw cycles and HZ10 for hot, humid climates like ours. Homes in Indian Shores should be sided with HZ10-rated HardiePlank, which is formulated for consistent heat and moisture exposure rather than freezing temperatures.
Yes — homes here get more direct salt spray and sustained wind-driven rain than inland properties, which puts more emphasis on corrosion-resistant fasteners, thorough flashing at every penetration, and holding proper clearance from grade and hardscaping. We also recommend periodic rinsing of the exterior to clear salt buildup, something inland homeowners generally don't need to worry about.
