If you searched "vinyl siding contractor" while researching your Redington Shores home, you're probably comparing materials, not just companies. That's the right instinct. Redington Shores is a narrow barrier island squeezed between the Intracoastal Waterway and the Gulf of Mexico, and the products that hold up fine forty miles inland don't always hold up the same way a block from Gulf Boulevard. We install James Hardie fiber cement siding exclusively — not vinyl, not LP SmartSide, not any engineered wood product — and we want to walk you through why, using this specific island's conditions rather than a generic sales pitch.
Vinyl siding is a reasonable, budget-friendly product in a lot of the country. On a Pinellas County barrier island it runs into a few specific problems. It's a petroleum-based plastic that softens and warps under sustained direct heat, and Redington Shores homes on the west side of the island facing the Gulf take that heat load daily. Vinyl panels also rely on loose-fit installation to expand and contract with temperature swings — that same loose fit is what lets wind-driven rain work its way behind the panels during a tropical system, and once water gets behind vinyl there's no drainage plane engineered to move it back out. And vinyl simply doesn't carry the wind ratings that Pinellas County's coastal construction code increasingly expects for homes this close to open water. We don't say any of that to bad-mouth the product — it's a fine choice in a lot of climates. It's just not the standard we're willing to put our name behind on this island, which is why fiber cement is the only siding we install here.
Redington Shores runs about a half-mile wide between the Intracoastal and the Gulf, which means almost every property on the island deals with some degree of direct salt exposure, whether you're on a canal off Bonna Bay or fronting the beach along Gulf Boulevard. That geography drives most of our material decisions here.
Airborne salt is corrosive to fasteners, coatings, and cladding joints, and it doesn't stop at the beachfront lots — it carries across the whole island on the prevailing onshore breeze. Homes set back from the water on the bay side still see meaningful salt exposure over a few storm seasons. Fiber cement's factory-applied ColorPlus finish is baked on and formulated to resist that kind of coastal fade and chalking far longer than a field-painted or extruded plastic surface holds up.
June through November, Redington Shores sits in the direct path of Gulf tropical systems, and even a storm that stays offshore can push heavy wind-driven rain sideways into a home's siding for hours. That's a different stress than a normal thunderstorm — it's rain being forced horizontally under pressure, looking for any gap, lap, or seam to exploit. Hardie board installed with the correct lap, flashing, and fastening pattern is built to shed that kind of driven moisture, and it holds its wind rating through storm-force gusts without the panel flex or blow-off risk vinyl siding carries in the same wind event.
James Hardie siding is made from cement, sand, and cellulose fiber, cured into a dense, dimensionally stable board. It doesn't expand and contract with heat the way vinyl or wood does, it isn't a food source for pests, and it's non-combustible, which matters for insurance underwriting on coastal Florida property as much as it does for fire safety. We install it in either the classic HardiePlank lap siding profile or the smooth HardiePanel look, depending on the architectural style of the home, always with James Hardie's HardieZone HZ10 formulation, which is the version engineered specifically for high-humidity, coastal climates like ours rather than the standard inland formulation.
Beyond vinyl, we also don't install LP SmartSide or other engineered wood composite sidings on Redington Shores homes. Those products perform reasonably well in drier inland climates, but they're wood-fiber based, and wood fiber absorbs moisture at the cut edges and fastener penetrations — exactly the vulnerable points that matter most in a barrier island rain event. Our position isn't that these products are worthless everywhere; it's that we've drawn a line on what we're willing to warranty our workmanship against on this specific island, and fiber cement is on the right side of that line.
Siding pricing on the island depends on more than square footage. Here's what actually moves the number on a typical Redington Shores project.
| Factor | Why It Affects Cost |
|---|---|
| Home elevation & access | Many island homes are elevated on pilings or block stem walls; scaffolding and lift access for upper stories adds labor time |
| Existing siding removal | Tear-off of old vinyl, wood, or aluminum siding and disposal adds a line item versus a bare-sheathing new build |
| Substrate condition | Salt-air corroded sheathing or fastener damage found during tear-off sometimes needs repair before new siding goes on |
| Siding profile & trim detail | Smooth panel vs. traditional lap, plus corner boards, frieze boards, and trim complexity on Old Florida-style homes |
| Color & finish | Factory ColorPlus finishes cost more upfront than field-painted but eliminate a repaint cycle for 15+ years |
| Flashing & moisture detailing | Proper window, door, and roofline flashing integration is labor-intensive but non-negotiable this close to the Gulf |
We walk every property in person before quoting, because two homes on the same street — one on a canal lot, one facing open Gulf water — can have meaningfully different scope even at similar square footage.
Fiber cement is heavier and less forgiving than vinyl, so the install itself is a different job. We start with a full tear-off and substrate inspection, repair any damaged sheathing, then install a code-compliant weather-resistant barrier before a single piece of siding goes up.
The details that separate a siding job that lasts twenty-plus years from one that fails in five are almost all moisture management: correct nail placement (not overdriven, which cracks the board and opens a water path), proper lap spacing per James Hardie's fastening schedule, sealed and back-flashed window and door openings, and a drainage gap where the siding meets grade or a lower roofline. On barrier island homes we pay particular attention to where siding meets the elevated foundation or piling structure, since that transition is a common spot for wind-driven rain to find a way in if it's not detailed correctly.
The island has a real mix of housing stock, and we tailor the siding profile to fit rather than pushing one look on every job.
Older single-family cottages closer to the Intracoastal side often carry a traditional Old Florida look — narrow lap reveal, simple trim, pastel or white tones. Newer and rebuilt homes, especially the elevated construction going up on piling foundations near the Gulf side, tend toward a cleaner, more modern coastal look with smooth panel siding and board-and-batten accents. HardiePlank and HardiePanel both come in a range of ColorPlus finishes that let us match either direction without compromising on the fiber cement performance underneath.
One of the practical advantages of fiber cement over vinyl on this island is how little ongoing attention it needs. A short annual routine keeps it performing:
Alpine Exteriors holds Florida license RB29003900, and we pull the required Pinellas County/Town of Redington Shores permits on every siding job — permitting on a barrier island isn't optional paperwork, it's part of how the county verifies the wind rating and flashing detail actually meet code for this flood and wind zone. We handle that process as part of the job rather than leaving it to the homeowner.
If you're comparing a vinyl siding contractor's quote against fiber cement, we're glad to walk your specific property, explain what we see, and give you a straightforward estimate — no pressure, no inflated numbers, just what your Redington Shores home actually needs. Use the form below to get started.
We've made fiber cement our exclusive standard for this island because of the direct Gulf salt exposure and wind-driven rain risk during storm season, and we only warranty the installation methods we trust in those conditions. We're happy to explain the specific trade-offs for your property so you can make an informed decision.
You can look up any Florida contractor's license number, including ours (RB29003900), through the Florida Department of Business and Professional Regulation's online license search. Always confirm the license is active and matches the exact business name on your contract before work starts.
James Hardie makes region-specific formulations, and HZ10 is engineered for high-humidity, high-moisture coastal climates like ours, versus the standard formulation built for drier inland regions. Installing the wrong zone formulation can shorten the product's real-world lifespan even though it looks identical off the truck.
Non-combustible, wind-rated materials like fiber cement can factor into windstorm coverage and premium calculations for coastal Pinellas County properties, though the exact impact depends on your carrier and overall roof and opening protections. It's worth asking your insurance agent directly once your siding project is scoped.
Yes, elevated homes need careful attention to the transition point where siding meets the foundation or piling structure, since that joint is a common entry point for wind-driven rain if it isn't flashed correctly. We detail that transition as a standard part of every elevated-home installation on the island.
