There are a lot of companies in Pinellas County that call themselves a "siding company" and then show up with whatever's cheapest to sell that week — vinyl one job, engineered wood the next, a composite panel line the week after. We don't work that way. Alpine Exteriors installs James Hardie fiber cement siding exclusively. Not because it's the only product on the market, but because after years of re-siding homes across the Gulfport area, it's the one we're willing to put our name and our warranty behind in this climate.
Gulfport sits right on Boca Ciega Bay, with salt air, high humidity, and a long, wet hurricane season that runs June through November. Vinyl softens and warps in sustained heat and can crack in a hard wind event. Engineered wood and LP-style products depend on perfect installation and ongoing maintenance to keep moisture out of the substrate — one missed detail and you're looking at swelling or rot a few years down the road. Fiber cement doesn't have those failure points. It holds paint, resists moisture intrusion when installed correctly, and it's rated for the wind exposure this part of Florida actually sees. That's the whole reason we narrowed our offering instead of broadening it.
We start with an on-site walk of the home — not a drive-by estimate. We're looking at the current siding condition, the substrate underneath (especially on older Gulfport bungalows where the original sheathing may need attention before new siding goes on), window and door flashing, soffit and fascia condition, and any moisture staining that points to an existing leak. We take real measurements, not a satellite-image guess, because Hardie board is ordered and cut to the job, not pulled generic off a shelf.
Most Gulfport homes we work on land on HardiePlank lap siding — it matches the traditional horizontal-board look of the older Florida cottages and bungalows in the historic district, and it's available in a range of exposures and ColorPlus factory-finish colors. Some clients pair it with HardieShingle for gable accents or HardieTrim around windows and corners. We walk through the options on-site with actual samples, not a catalog photo, so you can see how a color reads in Gulfport's direct sun before you commit.
Old siding comes off, the substrate gets inspected and repaired as needed, and a proper weather-resistive barrier goes on before a single piece of Hardie board is hung — that layer is what actually keeps bulk water out, and it's the step corners get cut on most often. Fasteners, gaps, and clearances follow James Hardie's published installation instructions, not shortcuts, because those specs are also what keeps the manufacturer's product warranty valid. We keep the site contained — landscaping protected, driveway and walkways swept at the end of each day, and your yard isn't a job site free-for-all overnight.
Before we consider the job done, we walk the exterior with you — every elevation, every corner, every trim detail. If something doesn't meet the standard we set for ourselves, we fix it before we invoice, not after.
A full re-side is disruptive by nature — there's no way around noise, dust, and crew presence for a stretch of time. What you shouldn't have to deal with is uncertainty about timeline or scope. Before work starts, you'll have a written scope, a realistic schedule, and a single point of contact for questions. Most single-family homes in the Gulfport area run somewhere in the range of one to three weeks depending on square footage, trim complexity, and whether there's substrate repair involved — we'll give you a specific window for your home, not a vague "a few weeks."
Florida weather is part of the plan, not an afterthought. Afternoon storms are routine here from June through September, and we schedule around them — materials get covered, exposed sheathing doesn't sit open overnight during active storm season, and if a named storm is tracking toward the Gulf, we'll talk with you directly about pausing or securing the site rather than pushing through.
"Lifetime warranty" gets thrown around loosely in this trade. There are two separate warranties on any Hardie siding job, and homeowners deserve to know exactly what each one covers before they sign anything.
| Coverage | Who Backs It | What It Covers |
|---|---|---|
| Manufacturer product warranty | James Hardie | Defects in the siding material itself — cracking, damage from termite exposure, and finish performance on ColorPlus products, per Hardie's published terms |
| Workmanship warranty | Alpine Exteriors | The installation itself — flashing, fastening, weather barrier detailing, and trim work performed by our crew |
| Standard vinyl siding installs (for comparison) | Varies by installer/brand | Typically shorter material coverage and installation warranties that are prorated or void after a change of ownership |
The manufacturer warranty only stays valid if the installation follows Hardie's specifications exactly — that's another reason we don't cut corners on flashing or fastener spacing. It's also why we only use crews trained on Hardie installation rather than general handymen splitting time between siding, roofing, and gutters. We'll go over both warranties in plain language before work starts, in writing, so there's nothing to interpret later.
Gulfport isn't a generic Florida market — it's a specific set of conditions. The city sits directly on Boca Ciega Bay, which means salt-laden air reaches homes well beyond the immediate waterfront, accelerating corrosion on fasteners and degrading lesser siding materials faster than inland Pinellas County. Add Florida's humidity, near-daily summer moisture cycling, and a hurricane season that regularly sends wind-driven rain sideways into wall assemblies, and you've got a climate that punishes any weak point in a siding system within a few years, not a few decades.
Gulfport's housing stock adds another layer. The historic district and neighborhoods like the Peninsula and Stetson area have a strong concentration of 1920s-through-'50s bungalows and Old Florida cottages, many with original wood siding that's been patched or overclad more than once. Getting the substrate right on these homes — checking for old rot, uneven furring, and outdated flashing — matters as much as the siding product itself. Newer construction closer to Pasadena Yacht and Country Club or along 49th Street tends to need less substrate work but faces the same wind and moisture exposure once the siding goes on.
We work throughout Gulfport proper — the historic downtown core, the waterfront homes along Shore Boulevard and Clam Bayou, and the residential neighborhoods stretching toward Pasadena Avenue — along with the surrounding south Pinellas communities including South Pasadena, St. Pete Beach, and the southern edge of St. Petersburg. If you're just outside that footprint, ask — we take on nearby jobs regularly and can tell you honestly if a project is outside a reasonable service radius.
Every home is different, so we don't quote off square footage alone. The factors that actually move the number on a Gulfport project are:
We put all of this in writing as part of the estimate, broken down by scope, so you can see exactly what you're paying for and why — not a single lump number with no explanation behind it.
Whoever you choose to re-side your home, ask these questions before signing anything:
A contractor who answers these plainly, in writing, before asking for a deposit is worth trusting more than one who talks fast and skips the details.
If your siding is showing its age, or you're planning ahead for a re-side before it becomes an emergency after storm season, we're glad to come take a look. Fill out the form below for a free, no-pressure estimate — we'll walk your home, answer your questions honestly, and give you a real scope and price before anything moves forward.
A repair addresses damaged sections only — cracked boards, storm damage, or a rotted area — while a full replacement removes all existing siding down to the substrate. Partial re-sides can work when the rest of the siding is sound, but matching older or discontinued profiles and colors gets harder over time. We'll tell you honestly which approach fits your home rather than upselling a full job you don't need.
Verify their Florida license directly rather than taking their word for it, ask whether their crew is factory-trained on the specific product they're installing, and get the workmanship warranty terms in writing before any deposit changes hands. Also ask how they handle scheduling around active storms, since that's a real factor for any exterior project on the Gulf Coast during hurricane season.
We narrowed to one product because it's the one that consistently holds up to Gulfport's salt air, humidity, and storm-season wind-driven rain without the maintenance and moisture risks that come with vinyl or engineered wood over time. Specializing in a single system also means our crew trains deeply on one set of installation specs instead of splitting attention across several products.
HardiePlank is horizontal lap siding that matches the traditional board-and-batten or clapboard look common on Gulfport's historic bungalows and cottages, while HardiePanel is a vertical sheet product more often used for accent sections, gables, or a more modern look. Most homes in Gulfport's older neighborhoods end up on HardiePlank for that reason, though we'll show you both in person before you decide.
Yes — proximity to the bay means salt-laden air reaches homes well beyond the immediate waterfront, which accelerates wear on lower-grade materials and fasteners faster than you'd see further inland. It doesn't rule out any particular Hardie profile, but it does affect fastener selection and flashing detail, which we account for on every Gulfport job regardless of how close the home sits to the water.
