We get this question a lot from homeowners in Largo: "Can you install real wood siding on my house?" Usually they've seen a craftsman-style home with cedar shakes, a farmhouse with board-and-batten, or an older Pinellas County house with cypress lap siding, and they want that same warm, natural look. It's a good instinct — wood siding has real charm. But as a licensed exterior contractor working in this specific climate, we don't install natural wood siding, and we want to explain exactly why, rather than just saying no and moving on.
Largo sits in a subtropical, high-humidity part of Pinellas County, wedged between Tampa Bay and the Gulf, with plenty of tree canopy, sprinkler systems running most of the year, and a long, wet hurricane season. That combination is genuinely rough on any wood product left exposed on an exterior wall. Instead, we install James Hardie fiber cement siding, which is engineered to give you the same board-and-batten, shake, or lap profiles you're picturing, without the maintenance cycle that real wood demands here.
This isn't a generic "wood is high maintenance" warning — it's about what actually happens to wood siding in this part of Florida over a normal ownership timeline.
Largo's average humidity sits high for most of the year, and afternoon thunderstorms are a near-daily summer occurrence. Wood siding absorbs moisture, swells, then dries and shrinks as conditions change. That constant expansion and contraction opens up joints, cracks paint or stain film, and eventually lets water behind the boards — which is where rot starts, usually from the inside out where you can't see it until it's advanced.
Pinellas County has a well-documented termite presence, including subterranean and drywood species that are active year-round in this climate (there's effectively no hard winter to slow them down). Untreated or under-maintained wood siding, especially anywhere it contacts soil, mulch beds, or trim near grade, is an easy target.
Largo isn't directly on the coast like Belleair Beach or Indian Rocks, but it's close enough to Tampa Bay and the Gulf that hurricane season (June through November) brings sustained wind-driven rain events. That kind of rain gets forced sideways into lap joints and butt seams on wood siding in a way that a light summer shower doesn't, accelerating exactly the moisture problems above.
Florida's UV index runs high most of the year. Stains and paints on wood siding chalk, fade, and break down faster here than in milder climates, which means the wood underneath loses its protective film sooner and more often than the finish schedule on the product label usually assumes.
Alpine Exteriors installs James Hardie fiber cement siding exclusively — we don't offer vinyl, LP SmartSide, or engineered wood products either. Fiber cement is a blend of cement, sand, and cellulose fibers, manufactured to hold sharp architectural profiles and deep wood-grain texture without the organic material that rot and termites actually feed on.
For homeowners chasing a wood look specifically, Hardie makes several profiles worth knowing about:
The result, from the curb, reads as wood — grain texture, shadow lines, board width — but the material underneath isn't organic, so it isn't food for termites and it isn't absorbing and releasing moisture the way a real cedar or cypress board does.
| Factor | Natural Wood Siding | James Hardie Fiber Cement |
|---|---|---|
| Moisture/rot risk in Largo's humidity | High — needs vigilant sealing and inspection | Low — non-organic material, engineered moisture resistance |
| Termite vulnerability | High if untreated or damaged | Not a food source |
| Repainting/refinishing cycle | Frequent, shortened further by Florida UV and rain | Factory ColorPlus finish holds color far longer |
| Storm and impact resistance | Moderate — depends on species and thickness | Engineered for wind-driven rain and debris resistance |
| Upfront material cost | Moderate to high depending on species | Moderate — competitive with quality wood, less than premium hardwoods |
| Long-term ownership cost | Higher — recurring maintenance and eventual board replacement | Lower — occasional wash, far less repainting |
Largo isn't a single climate zone — the material choice matters differently depending on where in the city you are. Homes closer to the Intracoastal side, toward Seminole or the Belleair border, deal with more salt-laden air on top of the humidity, which is even harder on unsealed wood. Inland neighborhoods around Largo Central Park or near Ulmerton Road get less salt exposure but plenty of tree canopy and sprinkler overspray, which keeps siding damp longer after rain. Either way, the underlying problem — sustained moisture contact with an organic material — is the same, just from different sources.
We also see a lot of older Largo homes, some from the mid-century boom years, that still have original wood or wood-composite siding patched together with decades of paint. When we're called out for a siding replacement estimate on one of these, it's common to find soft or delaminated boards hidden under paint that looked fine from the driveway. That's part of why we steer new installations toward fiber cement rather than replacing wood with more wood.
Getting the durability benefits of Hardie siding depends heavily on correct installation, not just the product itself. Our process on a Largo home typically includes:
That flashing and moisture-barrier work matters just as much as the siding material itself. Fiber cement resists rot far better than wood, but a poorly flashed window or a siding-to-grade gap that's too tight will still let water in behind any material.
One of the biggest quality-of-life differences homeowners notice after switching from wood to Hardie fiber cement is how little upkeep it demands. A simple annual routine covers most of it:
Compare that to a real wood siding maintenance schedule, which typically involves full repainting or restaining every few years in this climate, plus ongoing inspection for soft spots, insect damage, and joint separation.
James Hardie backs its siding products with a manufacturer warranty (specific terms vary by product line and finish — we'll walk you through the exact coverage for the profile you choose during your estimate). That warranty structure exists because the material is engineered and tested for climates like ours, not because it's being marketed as a wood substitute after the fact. When we install, we follow Hardie's installation specifications precisely, since improper installation is the most common reason a warranty claim gets denied — that's true of any manufacturer's siding product, not just Hardie.
From a resale standpoint, Largo buyers and inspectors increasingly recognize fiber cement siding as a durability upgrade over wood, particularly on homes closer to the water or with a history of moisture issues.
We're not going to tell you real wood siding looks bad — it doesn't. But installing it in a Pinellas County climate means signing up for a maintenance commitment that most homeowners underestimate until they're a few years in. Our professional standard is to install products that hold up to this specific environment with reasonable upkeep, which is why fiber cement is the only siding material we put on a Largo home. If the wood look is what you're after, we can very likely get you there with a Hardie profile that holds its finish and its shape far longer than the real thing would in this climate.

No, we only install James Hardie fiber cement siding. We've found that real wood siding doesn't hold up well long-term in Largo's humidity, storm season, and termite pressure, so we don't offer it even on request.
Check that they hold an active Florida contractor license, ask for proof of general liability and workers' comp insurance, and ask which siding manufacturers they're certified to install. A contractor who can explain why they use a specific product for this climate, rather than just quoting a price, is usually a better sign than the lowest bid.
HardiePlank is horizontal lap siding that mimics traditional wood clapboard, while HardieShingle is designed to look like cedar shake, often installed in a staggered pattern on gables or accent areas. Both come in smooth or wood-grain textures and can be factory-finished with ColorPlus paint.
Yes, and it's one of the more common projects we do here. We remove the old wood siding, inspect and repair the sheathing underneath for any hidden moisture damage, then install Hardie panels over a proper weather-resistive barrier.
Homes closer to the water deal with more salt-laden air, which is harder on unsealed wood and some finishes, so a durable, factory-finished material matters even more there. Fiber cement handles both the salt-air side of Largo and the inland, tree-shaded side well, which is part of why we use it citywide rather than switching materials by neighborhood.
