Alpine Exteriors installs one siding product in Lithia: James Hardie fiber cement. We don't carry vinyl, and we don't carry LP SmartSide or other engineered wood panels. That's not a marketing line — it's how we've decided to run this company. Vinyl softens, warps, and fades faster than most homeowners expect in Florida sun, and the seams and J-channels give moisture a place to collect against the wall behind it. Engineered wood siding relies on a treated wood substrate that has to stay sealed at every cut, joint, and fastener to hold up over time; miss one spot during install or years later during a repair, and moisture finds it. Fiber cement doesn't have that vulnerability. It's cement, sand, and cellulose fiber pressed and cured into a plank that doesn't rot, doesn't feed termites, and holds paint far longer than wood-based products. In a county with as much humidity, rain, and wood-boring insect pressure as Hillsborough, that difference matters more than the price gap on install day.
Lithia sits well inland from Tampa Bay — no barrier-island salt spray to worry about — but "inland" in this part of Florida doesn't mean easy on a house. We're still squarely in a humid subtropical climate with summer dew points that sit in the muggy range for months at a stretch, daily afternoon thunderstorms from June through September, and a hurricane season that runs June 1 through November. Wind-driven rain during a tropical system doesn't care that you're 25 miles from the coast; it drives water sideways into every gap a wall assembly has. Add in the fact that much of Lithia is still semi-rural — wooded lots, pasture, and creek bottoms along the Alafia River corridor — and you've got the two things that wreck lesser siding fastest: sustained moisture and a healthy local termite and carpenter ant population. Fiber cement shrugs off both. It's non-combustible, it won't swell or delaminate when it gets wet, and insects have no interest in it because there's nothing organic in it for them to eat.
Lithia isn't one kind of neighborhood, and we treat it that way. A big share of our calls come from FishHawk Ranch and the newer master-planned communities around Fishhawk Boulevard and Lithia Pinecrest Road, where homes are relatively young, HOA architectural standards are specific about siding profile and color, and the work is often a partial re-side after storm damage, a color refresh, or finishing an addition to match. The rest of Lithia is older and more rural — horse properties, larger acreage lots, homes built before the newer subdivisions went in — where we're more often doing a full tear-off and re-side on a house that's dealing with decades of wood siding fatigue or old vinyl that's had enough. Both situations call for the same product, but the install approach is different: HOA communities usually mean matching an approved color and profile exactly, while rural full re-sides give us more room to address moisture and ventilation issues in the wall assembly while everything is already open.
This is the horizontal lap board most Lithia homes use, and it's available in a smooth or cedar-textured finish. For traditional and craftsman-style homes common in FishHawk Ranch, we typically run a 7" or 8" exposure; for older ranch-style homes in rural Lithia, a wider exposure often reads truer to the original look.
Used as an accent on gables, dormers, or as full vertical siding on farmhouse-style builds — a look that's become common on newer construction in and around Lithia.
Fiber cement trim boards for corners, window and door casings, and fascia. Pairing Hardie trim with Hardie siding means the whole exterior expands and contracts at the same rate — mixing in wood trim is one of the most common causes of cracking and gapping we get called out to fix on other companies' work.
A proper install is a weatherproofing job first and a siding job second. We start by stripping the old siding down to the sheathing, checking for rot or moisture damage (common on rural Lithia homes where old caulking has failed for years unnoticed), and repairing anything compromised before a single new board goes up. Then comes a code-compliant weather-resistive barrier, correctly lapped and taped at every seam, flashed at every window and door. James Hardie's own installation specs are strict about fastener spacing, gaps at butt joints, and clearance off the ground and roofline — all details that matter more in a climate that throws wind-driven rain at a wall several times a summer than they would somewhere dry. We finish with a 100% acrylic paint system, either factory-applied ColorPlus or field-applied, both rated for Florida UV and humidity.
| Step | What We Check | Why It Matters Here |
|---|---|---|
| Tear-off | Sheathing condition, hidden rot, old flashing | Rural Lithia homes often have years of undetected moisture behind old wood or vinyl siding |
| Weather barrier | Correct lap direction, taped seams | Wind-driven rain during storm season attacks any gap |
| Flashing | Windows, doors, roof-wall intersections | These are the top three points of water intrusion on any Florida home |
| Fastening | Hardie-spec nail pattern and depth | Improper fastening voids the manufacturer warranty and causes early cracking |
| Finish | Caulk joints, paint system, trim seal | Determines how long the color and seal actually last in Florida sun |
| Factor | Lower Cost | Higher Cost |
|---|---|---|
| Scope | Accent or partial re-side (gable, addition match) | Full tear-off and re-side, whole house |
| Substrate condition | Sound sheathing, no rot found | Rot repair or sheathing replacement needed |
| Siding profile | Standard lap, factory ColorPlus finish | Vertical panel accents, custom trim details, field-applied paint |
| Access | Single-story, open lot | Two-story, tight lot lines, heavy landscaping to work around |
| HOA requirements | Standard approved color/profile | Custom color match or non-standard trim detail requiring extra coordination |
We won't quote a number without seeing the house — condition of the sheathing underneath old siding is the single biggest variable, and you can't know that from a drive-by.
Fiber cement is only as good as its installation. A rushed crew that skips flashing details, over-drives fasteners, or butts boards too tight will hand you callbacks within a couple of Florida summers — even though the material itself is rated to outlast most of what's built around it. We're a Florida-licensed contractor (RB29003900), we install to James Hardie's published specifications, and we'll walk you through exactly what we found once the old siding comes off, not after the new siding is already covering it up.
If you're weighing a full re-side, a storm-damage repair, or matching new siding to an addition anywhere in Lithia, we're happy to come take a look and give you a straight, no-pressure estimate — just fill out the form below.
Fiber cement is heavier and has to be cut, fastened, and gapped according to the manufacturer's specifications, which means more careful prep work and a slower install than snapping vinyl panels into place. It's also non-combustible and doesn't flex the way vinyl does, so the underlying weather barrier and flashing details have to be done correctly the first time. The payoff is a siding system that isn't relying on a thin plastic shell or a sealed wood substrate to keep water out.
Ask to see their Florida contractor license number and confirm it's active, ask whether they're a James Hardie-trained or preferred installer, and ask how they handle sheathing repair if rot turns up once old siding comes off. Get a written scope that specifies siding profile, trim details, and paint system rather than a vague one-line estimate. A contractor who won't walk you through what they found underneath your old siding before covering it back up is one to be cautious about.
James Hardie engineers its siding for different climate zones, and Florida falls into the HZ10 zone, formulated for high humidity, heavy rainfall, and hot sun exposure. HZ5 product is engineered for colder, drier climates and isn't what should go on a Florida home. We only order HZ10-rated Hardie product for Lithia installs, which is one more reason to confirm exactly what a contractor is quoting.
ColorPlus factory-finished Hardie siding is baked on and holds up considerably longer than a standard field-applied paint job, often 15 years or more before it needs attention, though intense Florida UV will still fade it gradually over time. Field-painted siding using a quality 100% acrylic exterior paint typically needs a fresh coat every 7 to 10 years in our climate. Either way, spot touch-ups on chips or scratches as they happen will stretch the time before a full repaint is needed.
No — Lithia is far enough inland to avoid direct coastal storm surge and salt spray, but it's still fully inside hurricane wind and rain exposure during the June-through-November season, and wind-driven rain does the same damage to a poorly flashed wall here as it does near the bay. Being inland mostly changes the risk from surge and salt corrosion to wind-blown debris and sustained tree-canopy moisture from the wooded lots common around here. Either way, correct flashing and a material that doesn't degrade when it gets wet matters just as much.
