If you searched for a wood siding contractor in Largo, there's a good chance you're picturing the look of natural cedar or cypress board siding — the warm, textured look that shows up in older Pinellas County neighborhoods and in a lot of home renovation photos. We get it. Real wood has a look nothing else quite matches at first glance. But we're going to be straight with you before you call anyone: we don't install natural wood siding, and we don't install engineered wood products like LP SmartSide either. We install James Hardie fiber cement siding exclusively, and in a climate like Largo's, that's not a marketing preference — it's a professional standard we hold to because we've seen what happens to wood-based products here.
This page explains why, what we install instead, and what it actually costs to re-side a home in Largo the right way.
Largo sits in the middle of Pinellas County, between the Intracoastal Waterway to the west and Old Tampa Bay to the east — close enough to the water on both sides that humidity is a year-round fact of life, not a seasonal one. That constant moisture in the air is the first problem for any wood-based siding product. Wood is dimensionally unstable when it absorbs and releases moisture over and over, and in a climate where the relative humidity rarely drops out of the comfortable range for mold and rot, that cycle never really stops.
Add in three more factors specific to this part of Florida, and you can see why we made the call we did:
None of that means wood siding is a bad product everywhere — it's a fine choice in a dry climate with low pest pressure. It's just not a good match for a Gulf Coast city like Largo, and as your contractor, we'd rather tell you that up front than sell you something we know will give you problems in five years.
A lot of the ranch-style homes built in Largo through the 1960s, 70s, and 80s went up with real wood board siding or wood-based panel products, and if you own one of these, you've probably already seen the wear firsthand — soft spots near the ground, peeling paint on the south and west-facing walls, or cupped and warped boards along the roofline where runoff hits repeatedly. We replace this kind of siding regularly. It's not a sign the original builders did anything wrong; it's just what four or five decades of Pinellas County humidity and sun do to wood.
James Hardie siding is made from cement, sand, and cellulose fibers, engineered specifically for climates like ours. It doesn't absorb moisture the way wood does, it's not a food source for termites, and it holds up to direct sun without the fiber breakdown that dries out and cracks wood siding over time. It's also non-combustible, which matters for insurance underwriting in some cases.
The part most homeowners are surprised by: Hardie makes several product lines specifically to replicate the look you were originally searching for.
The visual result is a home that reads as classic wood-sided architecture from the curb, while the material underneath is built for coastal Florida conditions rather than fighting against them.
| Factor | Natural Wood Siding | James Hardie Fiber Cement |
|---|---|---|
| Moisture / humidity response | Absorbs and releases moisture, prone to cupping and swelling | Dimensionally stable, engineered for wet climates |
| Termite resistance | Vulnerable, especially untreated boards | Not a food source for termites |
| Repainting cycle in Largo sun | Often every 3-5 years | ColorPlus finish rated for much longer intervals; even field-painted Hardie holds a finish longer than wood |
| Storm/wind-driven rain performance | Depends heavily on installation quality and maintenance | Consistent performance when installed to code with proper flashing |
| Typical lifespan here | Shorter, heavily maintenance-dependent | Multi-decade product warranty from the manufacturer |
| Upfront material cost | Often lower to moderate | Moderate, offset by lower long-term upkeep |
We get asked about vinyl and LP SmartSide often enough that it's worth addressing directly. Vinyl siding is inexpensive and easy to install, but it's a thin plastic product that can distort in intense heat and become brittle with age and UV exposure — not ideal for a climate that delivers both in abundance. Engineered wood products like LP SmartSide use wood strand cores with a resin coating; while they've improved over the years, they're still wood-based at the core, meaning they carry some of the same moisture-sensitivity concerns as natural wood if the factory coating is ever compromised at a cut edge or fastener point.
We're not saying either product fails everywhere — plenty of contractors install both successfully in drier climates. We've simply made fiber cement our standard for every home we side in Pinellas County, because it's the product we're comfortable standing behind with our license and our warranty in this specific environment.
The product is only half the equation — installation quality determines whether any siding performs the way it's supposed to. On every Largo project, our crews follow a consistent process:
Homes in Largo, like anywhere in Pinellas County, need exterior products that meet Florida Building Code wind-load and product-approval requirements, and we pull the required permits through the appropriate local building department before work starts rather than treating that as optional paperwork.
Every home is different, so we won't throw out a number that doesn't apply to your project — but these are the factors that move the estimate up or down:
We walk every property in person before quoting, because two homes of the same square footage can have very different scopes once you account for existing damage and detail work.
Fiber cement is genuinely lower-maintenance than wood, but "low-maintenance" isn't "no-maintenance." We tell every Largo customer the same short list: keep gutters clear so water isn't sheeting down the siding face, re-caulk joints and trim if you notice gaps opening over the years, and plan on repainting field-painted siding on a normal exterior-paint cycle if you didn't choose the factory ColorPlus finish. None of this compares to the sanding, scraping, and full repainting cycles that real wood siding demands, but a five-minute walk-around after major storms is still good practice for any siding product on the Gulf Coast.
Whoever you hire, verify their Florida license and insurance before signing anything, and ask specifically what product line they install and why. Alpine Exteriors holds Florida license RB29003900, and we install James Hardie fiber cement as our sole siding product for the reasons laid out above — not as an upsell, but because it's what we've found actually holds up around here. If you're comparing bids, ask every contractor the same direct question we'd want you to ask us: what happens to this siding in year ten, in this climate, on this coast.

James Hardie fiber cement siding has product testing and approvals used to meet Florida Building Code wind-load requirements when installed per manufacturer specifications. Performance in a storm still depends heavily on correct installation, especially flashing and fastening, which is why we follow Hardie's published specs exactly rather than field-guessing.
Ask for their Florida contractor license number and proof of insurance, ask what specific siding product line they install and why, and ask how they handle sheathing repair if damage is found during tear-off. A contractor who can answer all three clearly and specifically is worth far more than one offering the lowest bid.
HardiePlank is horizontal lap siding that mimics painted wood clapboard, while HardieShingle replicates the look of cedar shake in staggered or straight-edge panels. Homeowners often use HardiePlank across the main body of the house and HardieShingle as an accent on gables or dormers.
You can choose ColorPlus, a factory-applied finish baked onto the board before it ever reaches your home, or have the siding field-painted after installation. ColorPlus generally holds up longer against Florida's UV exposure and comes with its own finish warranty separate from the substrate warranty.
Yes — exterior wall products used in Pinellas County need to meet Florida Building Code wind-load and product-approval requirements, and siding replacement typically requires a permit through the local building department. We handle the permitting on our projects rather than leaving it to the homeowner.
