Why We Install Only James Hardie Fiber Cement Siding

Alpine Exteriors installs one brand of fiber cement siding in New Tampa: James Hardie. We don't offer vinyl, LP SmartSide, or off-brand fiber cement as a "budget option" alongside it. That's not a marketing gimmick — it's a decision about what we're willing to warranty our labor on. Vinyl siding expands and contracts with Florida's heat swings, can warp near dark colors or reflective windows, and has a shorter realistic service life. Engineered wood products carry moisture-related maintenance concerns that matter a great deal in a climate as humid as ours. James Hardie fiber cement gives us a product we trust to hold a straight reveal line, take a New Tampa summer without softening, and back its own materials with a warranty that outlasts most mortgages.

Specializing in a single manufacturer also means our crews aren't relearning fastening patterns, starter strip details, and caulking specs from job to job. Every Hardie install we do in New Tampa follows the same manufacturer-published installation instructions, which matters when it comes time to file a warranty claim — improper installation is the single most common reason siding warranties get denied, regardless of brand.

The James Hardie Product Line

James Hardie makes several distinct siding profiles, and part of our job is matching the right one to your home's architecture and your HOA's design guidelines — a real consideration in many New Tampa communities.

HardiePlank Lap Siding

The most common choice for New Tampa homes. Available in smooth, Select Cedarmill (light woodgrain), and Colonial Beaded profiles, with reveal widths that range from a traditional narrow lap to a wider modern lap. This is the workhorse product for ranch-style, colonial, and craftsman homes throughout Tampa Palms, Hunter's Green, and Live Oak Preserve.

HardieShingle Siding

A staggered or straight-edge panel that replicates a cedar shake look, often used as an accent on gables, dormers, or a full shake-style elevation. Popular on Craftsman and coastal-cottage designs.

HardiePanel Vertical Siding

Used for board-and-batten style exteriors, farmhouse accents, and porch gables — a look we're seeing requested more often on newer New Tampa builds and renovations.

Artisan Lap Siding

James Hardie's premium tier — a thicker board with a deeper, more authentic woodgrain texture and tighter reveal tolerances. It costs more per square foot but reads as a noticeably higher-end material up close, which matters on higher-visibility elevations.

HardieTrim

Matching trim boards for corners, window and door casing, and fascia, so the entire exterior envelope — not just the field siding — comes from the same engineered, moisture-resistant material.

ColorPlus Technology: A Factory Finish Built for Florida

How It's Applied

Field-painted siding is only as good as the paint job and the weather conditions the day it was applied. ColorPlus finishes skip that variable entirely — the color is baked on at the factory in a multi-coat process before the boards ever reach New Tampa, cured under controlled conditions no jobsite can replicate. The result is a finish that's more uniform, more resistant to fading, and more resistant to the kind of chipping and peeling that field-applied paint is prone to.

Why That Matters in Our Sun

New Tampa sits under some of the most intense UV exposure in the continental U.S. for much of the year. A factory-cured finish holds its color far longer under that kind of sun than a site-applied coat, and because the color runs through a consistent finishing process, you don't get the blotching or sheen differences that can show up with hand-rolled or sprayed paint on lap siding.

Touch-Up and Color-Matched Caulk

James Hardie sells color-matched touch-up kits and caulk for every ColorPlus color, so small nicks from lawn equipment or storm debris can be corrected without repainting an entire elevation.

The James Hardie 30-Year Warranty

James Hardie backs the siding board itself — the fiber cement substrate — with a 30-year, non-prorated limited warranty on their residential products. That's a warranty on the material's structural integrity: resistance to cracking, rotting, and damage from termites, which are real concerns for wood-based products in our climate but not for fiber cement.

The ColorPlus factory finish carries its own separate finish warranty, distinct from the substrate warranty, covering peeling, chipping, and fading of the factory-applied color. That's a meaningful distinction homeowners often miss: it's not one warranty, it's two — one for the board, one for the finish — and both come directly from James Hardie, not from us as the installer. Our labor warranty covers the installation itself, which is the piece that determines whether the manufacturer's warranty stays valid in the first place.

We always recommend homeowners register their warranty directly with James Hardie after installation and keep their paperwork. It's a simple step that's easy to forget once the crew has cleared out.

Engineered for Where You Actually Live: HZ5

Fewer homeowners know this, but James Hardie doesn't make one universal siding product for the whole country — they engineer formulations by climate zone. Florida falls in Hardie's HZ5 zone, which means the boards installed on your New Tampa home are formulated specifically for high-humidity, high-moisture, and higher pest-pressure regions, as opposed to the HZ10 formulation built for freeze-thaw climates up north. That's part of why we don't substitute in a generic fiber cement product from a smaller manufacturer — we're not just buying a brand name, we're buying a product engineered for exactly the humidity and moisture load New Tampa deals with nine months out of the year.

Built for New Tampa's Climate, Not Just Florida in General

Inland, But Not Immune

New Tampa sits well inland from Tampa Bay, so you're not dealing with direct salt spray the way homes on the coast are — but you're still squarely in Hillsborough County's wind-borne debris region, and you get the full brunt of hurricane season's wind-driven rain. Fiber cement's rigidity and moisture resistance matter just as much here as they do closer to the water; the risk profile is different, not lower.

Afternoon Storms and Humidity

Tampa Bay is regularly cited as one of the most lightning- and thunderstorm-prone areas in the country, and New Tampa gets its share of those near-daily summer downpours. Materials that trap moisture against a wall assembly create real mold and rot risk in a climate this humid. James Hardie's moisture resistance and our proper flashing and drainage-plane details at every install are both part of managing that.

Storm Season Wind Resistance

Proper fastening schedule and nail penetration matter as much as the product itself when it comes to wind performance. We install to James Hardie's published fastening specs for our wind zone, not a generalized "good enough" pattern, because that's what determines how the siding performs when a named storm comes through.

Matching New Tampa's Neighborhood Character

New Tampa is largely made up of newer, master-planned communities — Tampa Palms, Hunter's Green, K-Bar Ranch, Cory Lake Isles, Live Oak Preserve, Arbor Greene — many with active HOA architectural review committees that dictate approved colors, profiles, and sometimes even reveal widths. James Hardie's range of ColorPlus colors and profile options gives us the flexibility to hit HOA-approved palettes without stepping outside the product line, and their design tools let homeowners preview color and profile combinations against their actual home style before we ever cut a board. If your community requires an architectural review submission, we can provide the product specs and color documentation you'll need to get it approved.

What to Expect During Your Installation

Cost Factors to Understand Before You Budget

We don't quote pricing on a page like this, because it genuinely depends on your home's size, story height, existing siding condition, and profile choice — but these are the factors that actually move the number:

FactorWhy It Matters
Tear-off vs. new constructionRemoving existing siding and repairing sheathing adds labor
Profile and product tierArtisan runs higher than standard HardiePlank; HardieShingle accents add detail labor
Home height and roofline complexityMulti-story homes and cut-up rooflines increase scaffolding and trim work
Trim scopeFull HardieTrim package around windows/corners vs. reusing existing trim
Substrate repairRot or moisture damage found during tear-off is priced once uncovered, not guessed at upfront

Frequently Asked Questions

Is fiber cement siding installation different from a typical vinyl siding job?

Yes — fiber cement is heavier, requires specific blade types for cutting, and must be fastened to a manufacturer-published pattern to stay under warranty. It also requires more attention to flashing and drainage details since the boards themselves, unlike vinyl, are meant to be a long-term structural cladding rather than a lightweight overlay.

What should I ask a contractor before hiring them for a Hardie siding job?

Ask whether they're a James Hardie Preferred Contractor, ask to see their state license number, and ask specifically how they handle substrate repair if rot is found during tear-off. A contractor who can't answer fastening-pattern or flashing-detail questions clearly is a red flag regardless of what brand they're quoting.

Why does Alpine only install James Hardie instead of other fiber cement brands?

We standardized on one manufacturer so every crew member works from the same fastening specs, trim details, and warranty documentation on every job, which reduces installation errors. James Hardie's market track record and its climate-specific product engineering also give us more confidence backing the work with our labor warranty.

What's the actual difference between HardiePlank and the Artisan line?

Both are lap siding, but Artisan boards are thicker with a deeper, more textured woodgrain and tighter manufacturing tolerances for the reveal line, giving it a noticeably richer look up close. It costs more per square foot than standard HardiePlank, which is why we typically recommend it for higher-visibility elevations rather than the whole home.

Does New Tampa's climate call for anything different than a coastal Florida install?

New Tampa is inland enough that you're not dealing with direct salt spray, but you're still in Hillsborough County's wind-borne debris zone and get the full force of summer storms and hurricane season rain. We install to the same wind-zone fastening specs and flashing details regardless, since the humidity and storm exposure here are still significant even without coastal salt air.
