If you're a homeowner in Dover looking into vinyl siding, you deserve a straight answer before you spend a dollar: Alpine Exteriors doesn't install vinyl siding, and we don't install engineered wood products like LP SmartSide either. We install James Hardie fiber cement siding exclusively. That's not a sales gimmick — it's a standard we've held to because of what we've seen vinyl and engineered wood do on homes in this part of Hillsborough County over the years. This page walks through why, what we install instead, and what it actually costs to do it right.
Dover sits inland from Tampa Bay, tucked between Plant City and Brandon, in a stretch of Hillsborough County still shaped by strawberry fields and open agricultural land even as new rooftops keep filling in around them. That mix of rural character and suburban growth matters when you're choosing exterior materials — homes here face long stretches of direct, unshaded sun, high humidity that doesn't let up for months, and a storm season that runs June through November whether you're two miles or twenty miles from the water.
Vinyl siding is a plastic product, and plastic moves with temperature. In Dover's summer heat, panel surfaces can reach well over 130°F in direct sun, then cool significantly overnight. That constant expansion and contraction is exactly what vinyl siding is engineered to tolerate — but it's also why panels buckle, warp, and pull loose from their nailing strips over time, especially on south- and west-facing walls that take the brunt of the afternoon sun. Once a panel warps, it rarely lays flat again.
Dover isn't a coastal community, but it's not sheltered from tropical systems either. Inland Hillsborough County still sees sustained tropical-storm-force wind and, in a direct hit, hurricane-force gusts, along with the wind-driven debris that comes with severe thunderstorms in a rural-to-suburban area with plenty of trees. Vinyl siding is a thin, hollow product — it's vulnerable to cracking and blow-off in sustained wind, and once a section fails, the wall behind it is exposed to wind-driven rain. Fiber cement is a denser, solid material with a meaningfully higher wind-load rating when installed to manufacturer spec.
Vinyl siding's color is baked into the plastic itself, and that plastic breaks down under sustained UV exposure — the same UV exposure Dover gets nearly year-round given Florida's low latitude and long sunny season. Faded, chalky vinyl is one of the most common complaints we hear about from homeowners who had vinyl installed elsewhere years back. It's not a workmanship issue; it's the nature of the material.
Vinyl siding is installed as a "rain screen" that's meant to let water drain out from behind it — but that only works if the house wrap, flashing, and installation details behind it are done exactly right, every time, on every wall. In our experience, that's where a lot of vinyl jobs go wrong. Humidity in this part of Florida is high enough, for long enough, that any gap in that system becomes a moisture and rot problem behind the siding, often invisible until the damage is significant.
James Hardie fiber cement is a blend of cement, sand, and cellulose fibers, cured into a rigid board that doesn't expand and contract the way vinyl does, doesn't burn, and holds paint and factory color far longer than vinyl holds its pigment. It's heavier and more labor-intensive to install correctly, which is part of why it costs more upfront — but it's also why it holds up.
The most common choice for Dover homes, available in several plank widths and textures (smooth or cedar-grain), giving you the traditional lap-siding look without the material weaknesses of vinyl.
A staggered or straight-edge shingle profile that works well as an accent on gables, dormers, or a full elevation where a more textured, cottage-style look fits the home.
James Hardie's factory-applied color finish is baked on under controlled conditions and backed by its own finish warranty — it resists fading far better than field-applied paint or vinyl's molded-in color, which matters under Florida's sun exposure.
| Factor | Vinyl Siding | James Hardie Fiber Cement |
|---|---|---|
| Heat tolerance | Warps and buckles in sustained direct sun | Rigid, dimensionally stable in Florida heat |
| Wind resistance | Thin, hollow — prone to cracking, blow-off | Dense, solid board — engineered wind-load ratings |
| Color longevity | Fades and chalks under UV over years | ColorPlus finish resists fading, backed by warranty |
| Moisture behavior | Relies entirely on correct rain-screen install | Resists moisture intrusion when properly flashed |
| Fire resistance | Combustible plastic | Non-combustible |
| Upfront cost | Lower | Higher |
| Typical lifespan before major issues | 10–20 years in this climate | 30+ years with normal maintenance |
Dover's identity is still tied to agriculture — strawberry fields, irrigation systems, and open land border neighborhoods that have grown up around Plant City and Brandon's expansion. That inland setting means less salt exposure than the immediate coast, which is a genuine advantage for any exterior material. But it doesn't mean less humidity, less heat, or less storm exposure. Inland Hillsborough County still takes direct hits and heavy rain bands from tropical systems, and the summer heat here is as intense as anywhere in the Tampa Bay area, without an ocean breeze to temper it. A siding material has to handle both the daily grind of heat and humidity and the occasional violent weather event — that's the whole case for fiber cement over vinyl in this specific area.
A proper Hardie installation isn't just nailing boards to a wall — the prep work is what determines whether the siding performs for decades or fails early.
Every home is different, but a few things consistently move the price on a Hardie siding project in this area: the square footage and number of stories, how much of the existing wall assembly needs repair before new siding goes on, the plank profile and texture you choose, how much trim and detail work the home's architecture calls for, and access — homes on larger rural-style lots with mature trees or outbuildings sometimes take more staging and care than a standard suburban lot. We'll walk through all of that during an on-site estimate rather than quoting blind over the phone.
One of the practical arguments for fiber cement in a climate like Dover's is how little it asks of you afterward. Rinse it periodically to keep pollen, dust from nearby agricultural land, and mildew from building up, keep an eye on caulking around windows and trim every year or two, and touch up any impact damage promptly. Compare that to vinyl, which can't be repainted easily and often needs full panel replacement when it fails — with color-matching headaches years down the line as products change.
If you came to this page looking into vinyl siding, we'd rather tell you upfront why we won't install it than sell you something we don't believe holds up in this climate. If you'd like to see what James Hardie fiber cement would look like and cost for your specific home in Dover, request a free, no-pressure estimate below — we'll take a look at your walls, talk through your options honestly, and give you real numbers.
We've seen vinyl warp under sustained Florida heat, fade under UV exposure, and fail in wind and storm events more than we're comfortable standing behind. James Hardie fiber cement holds up better on all three counts, so it's the only siding product we install.
Confirm their Florida license is active and check what it covers — Alpine Exteriors holds Florida license RB29003900. Ask specifically what products they install and why, get everything in writing, and be wary of anyone quoting a full siding job without an in-person inspection first.
HardiePlank is a horizontal lap board, the traditional siding look most Dover homes use for full-wall coverage. HardieShingle has a staggered or straight shingle profile, usually used as an accent on gables or dormers, or on homes going for a more cottage-style appearance.
Yes — fiber cement is resistant to moisture intrusion and doesn't rot the way wood-based products can, which matters in an area with consistently high humidity and nearby agricultural irrigation. Proper flashing and installation are still essential to keeping moisture out from behind the boards.
For most homeowners planning to stay in their home long-term, yes — fiber cement typically lasts 30 or more years with normal care versus 10 to 20 for vinyl in this climate, and it avoids the fading and warping issues that often mean replacing vinyl sooner than expected. It comes down to whether you're optimizing for lowest upfront cost or lowest long-term cost.
