Type "siding company near me" from a Longboat Key address and you'll get a mix of national franchises, general contractors who occasionally do siding, and a handful of crews that actually specialize in it. That's a hard field to sort through from a search results page, because almost every listing claims to be local, experienced, and reliable. This page skips the general pitch and covers the things that actually differentiate a siding company worth hiring here: what our process looks like from first call to final walkthrough, what our warranty actually covers versus what the manufacturer covers, where our service area runs, and what a Longboat Key property specifically requires that an inland job doesn't.
We install James Hardie fiber cement siding exclusively — not vinyl, not LP SmartSide, not primed wood — and that decision shapes everything else on this page, from the warranty structure to how we scope a barrier-island installation. If you're comparing siding companies right now, the details below are the ones worth asking every contractor on your list.
Longboat Key is a narrow, roughly ten-mile barrier island that sits between the Gulf of Mexico and Sarasota Bay, and it's split between two counties — the north end falls in Manatee County, the south end in Sarasota County. That split matters for anyone doing exterior work here, because it can mean two different building departments, two different permitting timelines, and two different sets of local amendments to the Florida Building Code depending on which end of the island a home sits on. A siding company that only works one side, or only works the mainland and treats the island as an occasional job, often doesn't have that distinction sorted out before the estimate goes out.
It also means a genuinely local crew needs to be fluent in both jurisdictions, not just one. On top of that, a large share of Longboat Key properties — from beachfront condominium associations to canal-front and golf-course communities — carry their own architectural review requirements on top of whatever the county requires. Siding color, profile, and sometimes even fastening method can need association sign-off before a county permit is pulled. We factor that into scheduling from the start rather than discovering it mid-project.
This isn't a stocking decision — it's a standard we hold across every job. James Hardie fiber cement is non-combustible, holds up to the moisture and salt-air cycling that a Gulf-facing island puts on a wall system, and comes with a factory-applied ColorPlus finish that doesn't rely on a field paint job to hold its color. We don't install vinyl, LP SmartSide, or primed wood siding, and we're upfront about why: those products can be reasonable choices in some climates, but on a barrier island dealing with year-round humidity, intense UV, and an active hurricane season, we've found the long-term maintenance burden and moisture behavior aren't what we're willing to put our name behind. Hardie's climate-engineered HZ5 product line is built specifically for humid, high-moisture regions like this one, which is a meaningful part of why we standardized on it rather than carrying multiple product lines.
That single-product focus also means our crews aren't relearning installation details for a different material every other job. Fastener pattern, joint treatment, and flashing detail for Hardie siding become second nature when it's the only system you install, and on a coastal property those details are exactly where a mediocre installation starts failing first.
We walk the property, look at the current siding condition and substrate underneath where accessible, and talk through what you're trying to solve — full replacement, storm repair, or a renovation that includes new siding. On Longboat Key we also note which county the address falls under and whether the property is part of an association with its own architectural requirements, since both affect the timeline.
You get a written proposal covering the specific Hardie product and profile, color, estimated timeline, and price — not a verbal ballpark. If the property is in an HOA or condo association, we'll flag what documentation you'll likely need to submit for architectural approval before work can start.
We handle the county building permit application for the applicable jurisdiction — Manatee or Sarasota, depending on the address — and coordinate around any association approval process running in parallel.
Old siding comes off, the substrate gets inspected and any necessary repairs are made before new material goes up (this step gets skipped by crews in a hurry, and it's the step that determines whether the new siding actually lasts), and Hardie siding goes on to manufacturer fastening and flashing specifications suited to the wind exposure here.
We walk the finished job with you, address anything that needs a second look, and register the manufacturer warranty paperwork in your name.
| Phase | What Happens | Typical Timing |
|---|---|---|
| Assessment & proposal | Site visit, written scope and price, product selection | Within days of first contact |
| Association / permitting | HOA or condo approval where applicable, county permit application | Varies by association and jurisdiction |
| Installation | Removal, substrate repair, Hardie siding installation | Depends on home size and scope |
| Walkthrough & warranty | Final inspection, punch list, warranty registration | At project completion |
Longboat Key sits in a coastal zone with wind load requirements tied to its exposure to open Gulf water, and exterior work — siding included — needs to meet the Florida Building Code provisions that apply to that exposure category, not a generic inland standard. Fastening schedule, flashing detail, and in some cases product-specific wind ratings are part of what a permit reviewer checks, and it's why we install to manufacturer specifications rather than cutting corners on fastener spacing to save labor time. Because the island splits between Manatee and Sarasota counties, we also confirm which building department has jurisdiction over a given address before submitting anything, so the permit isn't delayed by a filing to the wrong office.
Two separate warranties apply to a Hardie siding job, and it's worth understanding the difference before you sign anything with any contractor.
| James Hardie Manufacturer Warranty | Our Workmanship Warranty | |
|---|---|---|
| Covers | The fiber cement material itself, and separately the factory-applied ColorPlus finish | Our installation labor and workmanship |
| Who backs it | James Hardie, the manufacturer | Alpine Exteriors, the installer |
| Transferable | Generally transferable to a subsequent homeowner per Hardie's terms | Terms provided in writing at contract signing |
| What voids it | Installation not performed to Hardie's published specifications | Handled directly with us — no manufacturer claim process required |
The material warranty is Hardie's commitment on the product; the workmanship warranty is ours, and it's the one that actually depends on who's on your roof doing the install. A siding company that doesn't offer its own separate workmanship coverage is asking you to rely entirely on the manufacturer's terms if something about the installation itself goes wrong — which the manufacturer warranty typically doesn't cover. We register the Hardie material warranty in your name at project completion and put our own workmanship terms in writing before the job starts, not after.
We work the full length of Longboat Key, on both the Manatee County and Sarasota County sides, along with the surrounding Sarasota and Manatee County mainland. If you're near the island but outside its town limits, reach out — we can generally tell you quickly whether an address falls inside our service area rather than making you guess from a coverage map.
If you're comparing us against other companies, here's what's genuinely worth checking on every one of them:
None of that requires taking anyone's word for it — licensing is public record, and a company confident in its process should be able to walk you through each of these without hesitation.

It depends heavily on home size, current siding condition, and whether an HOA or condo association approval process runs before the county permit. A straightforward single-family home is usually a matter of days to a couple of weeks once permitting clears; association-governed properties often add time on the front end for design approval rather than the installation itself. Verify their Florida contractor license directly with the state (ours is RB29003900), confirm they carry proper insurance, and ask for their workmanship warranty terms in writing before signing anything. Also ask specifically whether they've pulled permits in both Manatee and Sarasota counties, since Longboat Key spans both. Vinyl can be a reasonable product in some climates, but on a Gulf-facing barrier island dealing with intense UV, salt air, and hurricane-season wind loads, we've found it doesn't hold up the way we want siding on our jobs to hold up long-term. We standardized on James Hardie fiber cement instead and don't carry vinyl as an option. HZ5 is James Hardie's climate-engineered product line built for humid, high-moisture regions, and it's the specification we install in this area. It's formulated and rated differently than Hardie's products made for drier inland climates, which is part of why matching the right product to the region matters more than homeowners often realize. Yes, in a practical sense — the island's north end falls under Manatee County and the south end under Sarasota County, each with its own building department and permitting process. We confirm jurisdiction before filing anything so a permit application doesn't get delayed by going to the wrong office.Frequently Asked Questions
