Most exterior contractors in Pinellas County will sell you whatever siding is on the truck that week — vinyl, engineered wood, a generic fiber cement, sometimes all three. We don't. Alpine Exteriors installs James Hardie fiber cement siding, full stop. That's not a marketing angle; it's a decision we made because East Lake homes take a real beating from Gulf Coast humidity, afternoon thunderstorms, and the occasional named storm, and we'd rather stand behind one product we know inside and out than juggle three we half-trust.
James Hardie has been the dominant name in fiber cement siding for decades, and that market position matters for a homeowner in a practical way: parts, color-matched trim, touch-up paint, and installation know-how are all easy to find years down the road. A niche or off-brand product can leave you stuck if a panel gets damaged and the manufacturer has changed formulations — or disappeared. This page is about that specific brand, what it actually is, and why it holds up in East Lake's climate.
James Hardie siding is made from a mix of Portland cement, sand, and cellulose fiber, cured under pressure into dense, rigid boards. It's not "engineered wood" and it's not vinyl — it doesn't warp with heat like vinyl can on a west-facing wall in July, and it doesn't hold moisture and rot the way wood-based composite products eventually do. It's also non-combustible, which matters to some insurance carriers and to any homeowner who's watched wildfire coverage and wondered about their own exterior.
For East Lake specifically, James Hardie manufactures a formulation called HZ5, engineered for high-humidity, freeze-adjacent climate zones like ours along the Gulf Coast. It's not a generic board — it's built with our rainfall and moisture cycle in mind, which is a big part of why we don't substitute a cheaper fiber cement alternative even when a customer asks about it.
James Hardie isn't a single product — it's a family of siding and trim designed to work together. On East Lake homes we most often install:
| Product | What It Is | Where It Fits |
|---|---|---|
| HardiePlank Lap Siding | The classic horizontal lap board, in smooth or cedar-textured finish | The default for most East Lake ranch, colonial, and traditional homes |
| HardiePanel Vertical Siding | Large-format vertical panels, often paired with battens | Gable accents, modern-farmhouse and coastal-contemporary builds |
| HardieShingle Siding | Staggered or straight-edge panels that mimic cedar shake | Accent gables, dormers, and homes going for a cottage look near Lake Tarpon |
| HardieTrim Boards | Fascia, corner boards, and window/door trim in matching fiber cement | Finishing every project so trim doesn't rot while the siding holds up |
We spec the product mix to the house, not the other way around. A lot of East Lake's newer subdivisions favor clean horizontal lap with simple trim; some of the older lakefront and wooded lots near Lake Tarpon can carry a shingle accent or vertical panel gable nicely. We'll walk your home with you and talk through what actually fits the architecture before we talk pricing.
This is the part of the James Hardie brand that homeowners underestimate. Most siding — vinyl included — gets its color either baked in during extrusion (vinyl) or field-painted after installation (site-painted fiber cement, wood, most trim). ColorPlus Technology is different: the color is a multi-coat finish, baked onto each board at the factory in a controlled environment, before it ever reaches your house.
Why that matters in East Lake: field-applied paint has to fight our humidity and UV exposure from day one, and it's only as good as the weather conditions on the day it was rolled on. A factory-applied, oven-cured finish goes on in ideal conditions and bonds more evenly to the board. In practice, that means better fade resistance and better resistance to the kind of chalking and streaking you see on older painted siding around the lake after a few Florida summers. It also means color consistency panel to panel — no mismatched batches when a section gets replaced years later, because the finish and the board are backed by the same manufacturer record.
James Hardie offers ColorPlus in a range of collections, from muted traditional tones that fit East Lake's older established streets to the bolder Statement Collection shades some newer builds are using. If you'd rather paint after installation — some homeowners want a very specific custom color — Hardie also makes a primed product for that, and we're glad to install it either way. We just always start the conversation with ColorPlus, because for most homeowners it's genuinely the lower-maintenance, longer-looking-good choice.
James Hardie backs its siding with a 30-year limited transferable warranty on the fiber cement substrate itself — that's the board, not just the paint. Homes finished with ColorPlus get an additional finish warranty specifically covering the factory color against fading and peeling, separate from the substrate coverage. That's a meaningful distinction most homeowners don't hear explained: you're not just getting a warranty on "the siding," you're getting two warranties that cover two different things the product has to do — hold its shape and hold its color.
A few honest notes on what a warranty like this does and doesn't mean:
We bring this up not to oversell a number, but because a 30-year product warranty is a meaningfully longer runway than most alternative sidings offer, and it's one of the concrete reasons we standardized on this brand rather than a lower-cost fiber cement competitor.
East Lake sits in that inland-but-not-quite-inland pocket of Pinellas County — close enough to Lake Tarpon and the Gulf to get the same humidity load and storm exposure as the coast, without being directly on open water. That combination brings a few specific challenges:
Humidity and moisture cycling. Pinellas County runs high humidity nearly year-round, with a heavy summer rain season. Siding here goes through constant expansion and contraction with moisture, and materials that absorb water — wood, some composites — eventually swell, cup, or rot at the seams. Fiber cement doesn't absorb moisture the way wood-based products do, which is a big part of why it holds a flat, tight seam over years of East Lake summers.
Afternoon storms and wind-driven rain. Anyone in East Lake knows the pattern — clear morning, towering clouds by 2pm, a hard-driving thunderstorm by 4. Wind-driven rain finds every weak seam and gap in a siding system. Correct installation — proper overlap, fastening, and flashing at windows and corners — matters as much as the board itself, which is why we treat installation detail as part of what you're paying for, not an afterthought.
Hurricane season. June through November, East Lake homes need to hold up to sustained wind loads and wind-borne debris. Fiber cement's density and rigidity give it real advantages over lighter materials in wind events, and Hardie's installation specs are built around wind zone requirements rather than a one-size-fits-all approach.
Sun exposure. Florida's UV load is intense, and it's relentless on south- and west-facing walls. This is where ColorPlus earns its keep — a factory-cured finish holds color under UV exposure noticeably better than a standard field-applied coat, over the years most homeowners actually live in a house.
We don't publish blanket per-square-foot pricing because it genuinely varies by house, but these are the real factors that move a quote up or down:
| Factor | Why It Matters |
|---|---|
| Home size and wall complexity | More corners, gables, and dormers mean more cutting, trim, and labor time |
| Existing siding removal | Tear-off of old wood, vinyl, or damaged siding adds labor and disposal cost |
| Substrate condition | Rotted sheathing found once old siding comes off needs repair before new boards go up |
| Product selection | Standard HardiePlank vs. shingle accents vs. vertical panel gables carry different material and labor costs |
| ColorPlus vs. primed-for-paint | Factory finish carries a different price point than field-painting after install |
| Trim scope | Full HardieTrim replacement on fascia and corners adds cost but avoids mismatched old wood trim next to new siding |
The only way to get a real number is a walk-around and a measurement — we'll give you an itemized quote, not a rough guess, and we'll tell you plainly if we find rot or moisture damage once removal starts, before we do the work, not after.
If you're just starting to think about siding, the honest starting point is usually HardiePlank lap siding in a ColorPlus finish — it's the most proven, most widely used option, and it suits the vast majority of East Lake's home styles from traditional ranch to newer two-story construction. From there, the decision points are really about your specific house: does a gable or dormer suit a shingle accent, would a vertical panel section on a rear addition look intentional rather than mismatched, and does your HOA (several East Lake communities have architectural guidelines) have color or material restrictions worth checking before you fall in love with a particular shade.
We'd rather have that conversation in person, on your property, than guess at it here.

Carrying multiple brands lets a contractor upsell whatever has the best margin that month, not necessarily what performs best on your house. We chose one manufacturer we trust completely so our crews install it correctly every time, and we can speak to its performance with real confidence instead of a sales script.
Ask if they're a James Hardie-focused installer or a general siding contractor who occasionally uses it, ask to see their FL contractor license number, and ask how they handle rotted sheathing if it's found during tear-off. Also confirm in writing which ColorPlus color and which specific Hardie products are being quoted — vague quotes tend to become vague results.
Fiber cement is a category of material, and James Hardie is one manufacturer within it, not the only one. There are lower-cost fiber cement alternatives on the market, but we standardized on James Hardie specifically for its HZ5 humidity-zone formulation, ColorPlus finish options, and 30-year warranty structure.
HardiePlank is a horizontal lap board and is the standard choice for most full-house siding. HardieShingle mimics cedar shake in a staggered or straight-edge pattern and is more commonly used as an accent on gables or dormers rather than an entire home, though either can be used for a full house depending on the architectural style you're going for.
The core installation specs are the same, but homes closer to the lake and in lower-lying, tree-covered lots tend to hold humidity longer against exterior walls, so we pay extra attention to proper clearance from grade, mulch beds, and roof lines during install to keep moisture from wicking up into the siding over time.
