Ask five siding contractors in Pinellas County what they install and you'll usually get five different answers — vinyl for the budget jobs, LP SmartSide for the middle tier, fiber cement for the "upgrade." Alpine Exteriors doesn't work that way. We install James Hardie fiber cement siding, full stop. On a barrier island like Indian Shores, where salt air, humidity, and wind-driven rain hit a house from three sides — Gulf, bay, and sky — we've made the professional judgment that one brand's engineering, finish technology, and warranty structure holds up to the job better than the alternatives. This page is about that brand specifically: what James Hardie actually makes, how ColorPlus finish works, what the 30-year warranty really covers, and why the company's reputation matters when it's your home on the line.
This isn't a general "why choose fiber cement" page — we cover that ground elsewhere. Here we're talking about the manufacturer, not just the material category.
James Hardie makes several distinct siding profiles, and part of doing this job right is matching the right one to the right house. We don't push a single product on every home in Indian Shores — a Gulf-front condo-style single-family home and an older bay-side cottage often call for different lines.
The most common product we install. It's the classic horizontal lap look, available in multiple exposure widths and textures (smooth, cedar-mill grain). It's the right call for most Indian Shores single-family homes and townhomes where you want a traditional coastal look without the upkeep of real wood.
A textured, staggered-edge shingle profile that reads as a classic New England or Key West shingle look — popular as an accent on gables, dormers, or full elevations on some of the older beach cottages in the area that want that character without cedar shake's rot and insect issues.
Large-format vertical panels, often used with battens for a board-and-batten look. We see this specified on more modern coastal builds and on accent walls paired with HardiePlank on the main field.
Trim boards and soffit panels in the same fiber cement material, so the fascia, corner boards, and window trim age at the same rate and hold the same finish as the field siding — no mismatched wood trim rotting out next to siding that's holding up fine.
This is the part of the James Hardie brand that matters most in a place like Indian Shores. ColorPlus is Hardie's factory-applied finish system — the color is baked onto the board in a controlled plant environment, cured in multiple coats, before it ever reaches the jobsite. That's different from a job-site painted finish in a few concrete ways:
For a barrier-island home, salt aerosol in the air is a slow, constant low-grade assault on any painted surface. A finish designed and tested for that kind of exposure, rather than a standard exterior paint applied on-site, is a meaningful difference over a 15-20 year ownership horizon.
James Hardie backs its fiber cement products with a 30-year, non-prorated limited warranty on the siding substrate itself. In plain terms: it's not a warranty that shrinks in value the older the product gets, which is how a lot of building-product warranties are structured. The ColorPlus finish carries its own separate finish warranty, covering the coating specifically.
A few practical notes worth understanding before you sign anything:
| Warranty Element | What It Covers | Why It Matters in Indian Shores |
|---|---|---|
| Substrate warranty (30-yr, non-prorated) | Manufacturing defects in the fiber cement board itself | Full value protection over decades, not a declining percentage |
| ColorPlus finish warranty | Finish cracking, peeling, or fading outside spec | Salt air and UV are the two things most likely to stress a coastal finish |
| Transferability | Warranty can generally transfer to a new owner | Relevant on a barrier island where properties turn over as vacation/rental homes |
| Installation requirement | Coverage assumes installation per Hardie's published specifications | Why proper fastening and clearances matter — see below |
That last line matters more than most homeowners realize: a manufacturer warranty on a building product is only as good as the installation underneath it. We follow Hardie's published installation specifications on every job — proper fastener type and spacing, correct clearance from grade and roof lines, proper joint treatment — specifically so the warranty stays intact if you ever need it.
James Hardie invented fiber cement siding as a mass-market product category and has remained the dominant name in it for decades — that matters practically, not just as a marketing point. A company with that market position has the scale to fund climate-specific engineering (Hardie designates specific product formulations for different climate zones, including humid, high-moisture regions like ours), maintain consistent quality control across manufacturing runs, and stand behind a 30-year warranty because it isn't going anywhere. When a homeowner is deciding what to put on the outside of a house that faces the Gulf, the manufacturer's staying power and track record are part of the actual risk calculation — not a soft brand preference.
It's also why we don't mix brands or substitute a cheaper fiber-cement competitor mid-project to save money on a job. The engineering, the finish system, and the warranty are designed as one package.
Indian Shores sits on a narrow barrier island in Pinellas County, sandwiched between the Gulf of Mexico and Boca Ciega Bay — meaning almost every home here gets some degree of salt-laden air exposure, whether it's a Gulf-front condo-style property or a home a few blocks in toward the Intracoastal side. Add Florida's long, humid hurricane season (June through November) and the wind-driven rain that comes with it, and you've got a climate that's genuinely hard on building materials.
| Material | Salt air / corrosion | Moisture & humidity | Wind & impact resistance | Long-term maintenance |
|---|---|---|---|---|
| Vinyl | Doesn't corrode, but UV and heat cause fading/warping over time | Can trap moisture behind panels if not installed with care | Can crack or blow off in high wind if fastened loosely | Low, but limited repair options once faded or brittle |
| Engineered wood (e.g., LP SmartSide) | Wood-based core is vulnerable to moisture intrusion over time | Higher risk of swelling/delamination in sustained humidity | Generally solid if installed correctly | Requires more diligent caulk/paint upkeep |
| Real wood | No metal corrosion issue, but vulnerable to rot and insects | High — wood absorbs moisture and needs regular sealing | Moderate; depends on species and installation | Highest — repainting, sealing, and rot repair are ongoing |
| James Hardie fiber cement | Non-organic, does not rot or corrode from salt exposure | Engineered for high-moisture climate zones | Rigid, heavy board with strong wind-load performance when properly fastened | Low — ColorPlus finish extends the repaint cycle significantly |
This is the practical reasoning behind installing only one product line: on a barrier island, the material's behavior in salt air and sustained humidity isn't a cosmetic concern, it's a structural and financial one over a 20-30 year ownership window.
Fiber cement siding is only as good as the installation behind it, and James Hardie is explicit that its warranty assumes installation to spec. On Indian Shores properties specifically, we pay close attention to:
None of this is unique marketing — it's the baseline for keeping the manufacturer's warranty valid and, more importantly, keeping water out of your walls in a place that gets a lot of it.
Whether you're re-siding a bay-side home that's showing its age or replacing storm-damaged siding on a Gulf-front property, the underlying decision is the same: pick a product engineered for this specific climate, backed by a manufacturer with the track record to stand behind a 30-year warranty, and have it installed to spec by someone who treats the fastening schedule and moisture barrier as seriously as the finish color. That's the whole basis of how we approach every siding job in Indian Shores.

Most single-family homes take roughly one to two weeks from start to finish, depending on the home's size, the number of stories, and how much trim and detail work is involved. Weather is the biggest variable during hurricane season, since wind-driven rain can pause exterior work for safety reasons. We'll give you a realistic timeline specific to your property before work starts.
Ask whether they're a licensed Florida contractor (Alpine Exteriors holds FL license RB29003900), whether they carry liability insurance and workers' comp, and whether they'll install strictly to James Hardie's published fastening and clearance specifications so the manufacturer's warranty stays valid. Also ask to see fiber cement projects they've completed nearby, since coastal installation detail work is different from inland jobs.
No — Alpine Exteriors installs James Hardie fiber cement exclusively. We've made that a standard, not a menu option, because vinyl and engineered wood products carry real trade-offs in a salt-air, high-humidity environment like this one, and we'd rather build a project around one material we trust fully than offer a cheaper option we'd have reservations about.
HardiePlank gives you the classic horizontal lap look and is the most common choice for full-house siding in this area. HardieShingle mimics a staggered cedar-shake look and is often used as an accent on gables or dormers, or on older cottage-style homes going for that specific character — both carry the same ColorPlus finish and warranty structure.
Yes — as a narrow barrier island between the Gulf and Boca Ciega Bay, many properties fall under specific flood zone and coastal construction requirements set by Pinellas County and the Town of Indian Shores. We handle the permitting details for you and make sure the installation meets local code requirements for this location, not just generic statewide minimums.
