North Redington Beach is a narrow strip of Pinellas County squeezed between the Gulf of Mexico and the Intracoastal Waterway, and that geography shapes everything about how a home's exterior needs to be built. Whether your house sits directly on Gulf Boulevard a block from the sand or back toward the Narrows on the bay side, salt air, humidity, and wind are working against your siding every single day, not just during a named storm. Alpine Exteriors is a licensed Florida contractor (RB29003900) that installs siding for homeowners up and down this stretch of barrier island, and we do it with one product family: James Hardie fiber cement. We don't sell vinyl, LP SmartSide, or any engineered wood siding, because none of those materials hold up to what a Gulf-front or near-Gulf home in Pinellas County goes through year after year.
This page covers how we approach a siding project specifically in North Redington Beach — our process, what the warranty actually covers, what to expect on a barrier island lot, and how to reach us for a free estimate.
Vinyl siding is inexpensive and easy to install, which is exactly why so much of it ends up on Florida homes. It's also a poor match for this environment. Vinyl expands and contracts with heat, and on a west-facing wall that bakes in Gulf sun all afternoon, panels can warp, buckle, or pull away from their fasteners over time. Its color is also baked all the way through a thin plastic sheet, so intense UV exposure — which North Redington Beach gets in abundance — fades and chalks the surface faster than most homeowners expect.
Engineered wood products like LP SmartSide use a wood-strand core with a resin coating. That coating is a single line of defense. Once it's compromised — by a fastener hole, a joint that wasn't sealed correctly, or years of humidity working at a seam — moisture reaches the wood core, and the material starts to swell and deteriorate from the inside, often before it's visible from the outside.
James Hardie fiber cement is cement, sand, and cellulose fiber. It doesn't have an organic core to rot, it isn't a food source for termites or wood-boring insects, and it doesn't soften when it takes on moisture. It holds its shape in heat and doesn't warp on sun-exposed walls. That's not a marketing claim we're making — it's why we, as a licensed contractor putting our name and warranty behind every job, standardized on one material instead of offering several.
James Hardie manufactures different formulations of its siding for different regions of the country, called HardieZone products. Florida — including all of Pinellas County — falls in the humid, high-UV HZ5 zone, and the siding we install is engineered for exactly that combination of moisture and sun exposure. The factory-applied ColorPlus finish is baked on and warrantied separately from the substrate, which matters on a barrier island where a painted surface facing the Gulf takes far more UV and salt exposure than the same wall would take twenty miles inland.
We start with an on-site look at your home's current siding, sheathing, and trim condition, not just a measurement. On older North Redington Beach homes — plenty of which date to the 1960s and '70s beach-cottage boom — we're checking for water intrusion around windows, soft spots in the sheathing, and any prior repairs that were patched rather than properly resolved. We'll walk you through what we find before we ever talk numbers.
Existing siding comes off down to the sheathing (or, in some cases, we can install directly over sound existing siding — we'll tell you honestly which situation you're in). Any damaged or spongy sheathing gets replaced, not covered up. This is the step that determines how the next thirty years of the wall behave, so we don't rush it.
A correctly lapped weather-resistant barrier and properly flashed windows, doors, and penetrations go on before a single piece of Hardie board. On a barrier island lot where wind-driven rain is a real, recurring event rather than a rare one, this layer is what actually keeps water out of the wall assembly — the siding itself is the second line of defense, not the first.
We install per James Hardie's published fastening and clearance specifications, including the ground-clearance and roof-line clearances the manufacturer requires to keep water from wicking up into the bottom of the boards. Corners, trim, and joints get sealed with a compatible sealant, and seams are staggered so the wall reads clean, not patchworked.
Caulking, touch-up, and a full site walk-through with you before we call the job done. We haul our own debris — you're not left with a dumpster or a yard full of cut-offs.
Exterior work in North Redington Beach requires a building permit, and depending on your lot's flood zone designation, that can mean additional review — a meaningful share of homes on this barrier island sit in AE or VE flood zones, and many are elevated on pilings or a raised foundation. We pull the required permits as part of the job and coordinate inspections, so you're not the one tracking down the town or county on your own. If your home is elevated, we account for access and staging around the understructure when we scope the work, since that changes both the approach and the timeline compared to a standard slab-on-grade home.
If you're in a condo or a homeowners' association — common along this stretch of Gulf Boulevard — exterior changes often need board approval before work starts. We're glad to provide product specs, color samples, or documentation your association requires as part of that process.
| Coverage | What It Includes | Backed By |
|---|---|---|
| Substrate (the board itself) | Manufacturing defects in the fiber cement material | James Hardie limited warranty |
| ColorPlus finish | Coating defects including cracking, peeling, and chipping under normal conditions | James Hardie limited finish warranty |
| Installation labor | Improper installation, flashing, or fastening by our crews | Alpine Exteriors workmanship warranty |
We explain both warranties in plain language before the contract is signed, including what's covered, what isn't, and what would void either one — things like painting over a ColorPlus finish with an incompatible product, which some homeowners don't realize can affect coverage.
| Factor | Why It Matters |
|---|---|
| Tear-off vs. install-over | Removing old siding and inspecting/repairing sheathing adds labor but protects the wall long-term |
| Siding profile | Lap siding, shingle-style panels, and vertical board-and-batten each price differently in materials and labor |
| Trim and architectural detail | Homes with more corners, dormers, or decorative trim take more cutting and finishing time |
| Home height and access | Two-story and elevated homes require more scaffolding/staging |
| Color | Factory-applied ColorPlus finishes vs. field-painted Hardie board affect both cost and long-term fade resistance |
We give you a written, itemized estimate so you can see exactly where the cost comes from — not a single lump number.
We work throughout this section of the Pinellas barrier islands — North Redington Beach, Redington Shores, Redington Beach, Indian Shores, and neighboring Gulf Boulevard communities — along with inland Pinellas County. Whether your home is a raised beach cottage a block off the sand or set back on the bay side away from direct Gulf exposure, the salt air and humidity reach every wall on this island, and we build accordingly.
If you're weighing a siding project — repair, partial replacement, or a full re-side — we're happy to come look at your home and walk you through what we see, no pressure and no obligation. Use the form below to request a free estimate.
Yes, exterior siding work requires a building permit, and homes in flood zones may need additional review before work starts. We pull the permits and schedule inspections as part of the job so you're not managing that process yourself.
Confirm the contractor holds an active Florida license, carries liability and workers' comp insurance, and can explain in writing how they handle flashing and moisture barriers, since that detail matters more here than the siding brand itself. Ask what happens if they find damaged sheathing during tear-off, and get that answer in writing before signing.
Vinyl can warp and fade under sustained sun and heat, and engineered wood products rely on a surface coating to keep moisture out of a wood core. Fiber cement doesn't have that vulnerability, which is why we standardized on one product line instead of offering several.
HardiePlank is a traditional horizontal lap board, the most common look on Gulf Coast homes, while HardieShingle mimics a staggered or straight-edge shingle appearance often used as an accent on gables or full facades for a more coastal-cottage look. Both carry the same fiber cement durability; the choice comes down to the style you want.
Homes raised on pilings or a stem wall change staging and access, and materials near the base of the structure need attention to clearance and flashing since that area sees more wind-driven rain exposure. We assess this during our on-site walkthrough so the estimate reflects your home's actual structure, not a generic slab-on-grade job.
