If you're researching siding companies in Dunedin, you've probably noticed the search results are a mix of national franchises, one-truck operations, and everything in between. That's a hard field to sort through when the job in front of you is your own house. Dunedin's housing stock adds another layer to it: you've got original block-and-frame bungalows near downtown and the Pinellas Trail, mid-century cottages tucked into the older platted neighborhoods, and newer construction closer to Curlew Creek and the Alt 19 corridor. Each of those homes ages differently in this climate, and the siding company you hire needs to actually understand that difference, not just show up with a nail gun and a truckload of whatever material is cheapest that month.
This page is about us as a company — how we're set up, how a project runs from first call to final walkthrough, what our warranty actually covers, and where we work. If you want a deeper look at fiber cement as a material or at the James Hardie product lineup specifically, that's covered elsewhere on our site. Here, the focus is on what it's like to actually hire us.
Alpine Exteriors installs James Hardie fiber cement siding exclusively. We don't sell vinyl, LP SmartSide, or other engineered wood panel systems, and we're not going to pitch you on one as a "budget option" during your estimate. That's a deliberate business decision, not a marketing line.
Every siding material has real trade-offs — cost, installation sensitivity, moisture behavior, appearance over time, warranty structure. Vinyl is inexpensive and light, but it expands and contracts a lot in Florida's heat swings and can look and perform differently than fiber cement over a 15-20 year span. Engineered wood products carry their own moisture-management requirements that a crew has to get exactly right, every time, in a humid coastal climate. Rather than train our installers across three or four systems and hope they remember which detail applies to which product, we standardized on one: James Hardie fiber cement. Our crews install it as their full-time trade, not as one option among several they rotate through.
That focus also means our estimating, our flashing and fastening details, and our warranty paperwork are all built around a single system instead of being generic templates stretched across different products.
The first visit is a walk-around of the exterior, not a sales pitch delivered from a laptop. We look at your current siding condition, trim and window detailing, soffit and fascia, and anywhere we can see evidence of past moisture issues — soft spots, staining, or gaps around penetrations. In older Dunedin homes near downtown, we're also checking whether the original sheathing is sound enough to fasten into directly or needs attention first. You get a written estimate that spells out the Hardie product and profile, the underlying weather-resistive barrier, and the scope of any trim or flashing work — not just a single lump-sum number.
We remove the old siding down to the sheathing and inspect it before anything new goes up. Any rot, delamination, or insect damage gets addressed at this stage — covering a compromised substrate with new siding just hides a problem that gets worse behind the wall. This is also when we address any older, non-code flashing details we find, particularly around windows and roof-to-wall intersections, which tend to be the weak points on houses that have been through a few decades of Gulf coast humidity and storm seasons.
A correctly installed weather-resistive barrier and properly lapped, sealed flashing at every penetration matter more to long-term performance than the siding itself. We install these per James Hardie's published installation requirements, with particular attention to window and door head flashing, kick-out flashing at roof lines, and clearance from grade, decks, and roofing — all details that keep water moving out and away from the wall assembly instead of trapped behind it.
Hardie panels and lap siding are fastened, gapped, and finished according to manufacturer specification — correct fastener type and spacing, proper joint treatment, and factory-primed or ColorPlus-finished edges caulked or capped as the product line requires. This is also where crew consistency shows: skipping or shortcutting fastening specs is the single most common cause of premature siding failure, and it's not something you can see just by looking at a finished wall from the street.
We walk the finished exterior with you, point out anything worth noting (like touch-up caulk lines or trim details), and make sure the site is cleared of debris, packaging, and fasteners before we consider the job done.
A siding company is really only as good as the people actually driving the fasteners. We keep our installation crews in-house rather than rotating through a revolving door of day-labor subcontractors, because consistency on flashing and fastening details is exactly the kind of thing that erodes when a crew changes every few weeks. Crew members are trained specifically on James Hardie installation requirements — fastener patterns, clearances, joint treatment, and flashing sequencing — because that's the one system they work with. We'd rather have a smaller team that knows this product cold than a large bench that's generalist across five different siding types.
One of the most confusing parts of comparing siding companies is that "warranty" can mean very different things depending on who's talking. There's the manufacturer's product warranty, and then there's the installer's workmanship warranty — and they don't automatically cover the same failures.
| Coverage | Who Backs It | What It Covers |
|---|---|---|
| Hardie product warranty | James Hardie | Manufacturing defects in the fiber cement product itself, non-prorated for a long term as published by James Hardie |
| ColorPlus finish warranty | James Hardie | Factory-applied finish performance — fade and peel resistance — on ColorPlus finished products specifically |
| Alpine Exteriors workmanship warranty | Alpine Exteriors (RB29003900) | Installation-related issues: fastening, flashing, joint treatment, and general installation quality on our work |
We'll walk you through exactly what's covered under each during your estimate and put the specific terms in writing — we'd rather you understand the coverage before the job starts than find out what it means later, when it actually matters.
We work throughout Dunedin, from the historic downtown grid near Main Street and the Pinellas Trail out to the neighborhoods off Curlew Road and Alt 19, and over toward the waterfront streets near the Dunedin Causeway and Honeymoon Island. Coastal-adjacent homes near the causeway and the barrier island approach deal with more salt air exposure than inland properties closer to Curlew Creek, which affects how fasteners, trim, and finish coatings hold up over time — something we factor into product selection and detailing on those jobs specifically. We also cover the broader Pinellas County area bordering Dunedin, including nearby Clearwater and Palm Harbor neighborhoods.
Every project timeline varies with scope, but here's the general shape of what a Dunedin siding job with us looks like:
Whether you go with us or someone else, these are worth asking every siding company you're considering:

A siding contractor specializes in exterior cladding installation and typically holds product-specific training, while a general contractor manages broader construction and may subcontract the siding portion out. For a full siding replacement, working directly with a specialized siding company usually means more consistent installation quality and clearer accountability.
In Florida, ask for the contractor's state license number and confirm it's active, along with proof of general liability and workers' compensation insurance. Alpine Exteriors holds Florida license RB29003900, which you're welcome to verify independently before hiring anyone.
Vinyl and engineered wood are generally less expensive upfront and faster to install, which keeps them common among companies competing mainly on price. We made a professional decision to install only James Hardie fiber cement because we'd rather stand behind one system we know thoroughly than offer options with trade-offs we're not comfortable recommending.
HardiePlank is a horizontal lap board, the most common look on traditional Florida homes, while HardiePanel is a large vertical sheet often used for board-and-batten styling or accent sections. Both are the same fiber cement material — the difference is profile and the architectural look you're after.
Yes — homes closer to the Dunedin Causeway and Honeymoon Island see more salt air exposure than inland properties near Curlew Creek, which can affect fastener choice, trim detailing, and how finishes hold up over time. We factor that in on coastal-adjacent jobs rather than using identical detailing everywhere in the service area.
