Two Fiber Cement Products, One Standard
When homeowners in St. Petersburg start comparing siding, they usually expect the big fork in the road to be vinyl versus fiber cement. But once a homeowner has decided on fiber cement, there's a second decision most people never see coming: which fiber cement. Allura and James Hardie are both legitimate manufacturers of the same basic material — cellulose fiber, sand, and portland cement pressed into planks and panels. They are not vinyl and wood pretending to be something else. That's an important distinction, and it's why this page reads differently than our pages on vinyl siding or primed wood.
We install only James Hardie products. Not because Allura is a scam or a knockoff, but because after years of installing fiber cement on homes across Pinellas County, we made a business decision to standardize on one manufacturer's system — end to end, from the factory finish to the fastener schedule to the warranty paperwork. This page explains what that decision actually rests on.

What Allura Gets Right
Fair is fair. Allura fiber cement is non-combustible, resists rot and pest damage the way any properly formulated fiber cement product does, and holds paint or factory finish far better than wood siding ever will. It's manufactured to recognized fiber cement standards, it's sold through legitimate building supply channels, and plenty of licensed contractors install it competently. If your only question is "fiber cement versus vinyl or wood," Allura clears that bar the same way Hardie does.
Where the two products separate is in the details that matter most once the siding is actually on a house exposed to a Tampa Bay hurricane season, not in a showroom.
Why We Standardized on One Manufacturer's System
Climate-Engineered Product Lines
James Hardie sells its siding under a zoned system, with product formulations and installation specs tuned to different climate exposures — including a line engineered specifically for hot, humid, high-moisture regions like the Gulf Coast. That means the plank we put on a house in St. Petersburg is formulated with this exact climate in mind: heavy humidity, wind-driven rain, and long stretches of intense UV. Allura also makes claims about climate suitability, but Hardie's zoned approach is the system our crews have trained on, tested against, and installed for years in this specific market. Switching between two manufacturers' zoned specifications on the same job site is where installation mistakes creep in.
Factory-Applied Finish System
Both companies offer factory-applied color finishes rather than relying entirely on field painting. Hardie's ColorPlus finish is a multi-coat, baked-on process applied under controlled factory conditions, paired with color-matched caulk and trim so the finish behaves as one integrated system rather than a plank finish plus a separate field-applied caulk and trim finish that can weather at different rates. We know this system's touch-up products, its color-match sourcing, and its long-term fade behavior in Florida sun because it's the only factory finish our painters and installers work with. That familiarity is worth more to a homeowner than it sounds — a crew that has cut, fastened, and finished the same product hundreds of times makes fewer of the small errors that cause callbacks.
One Crew, One Spec, Fewer Failure Points
Most fiber cement failures aren't material failures — they're installation failures: wrong fastener pattern, missing clearance at grade, unsealed butt joints, wrong caulk for the finish system. Every manufacturer publishes its own installation manual with its own tolerances. A crew that installs two different fiber cement brands has to keep two different rulebooks straight, job after job. We removed that risk by carrying one rulebook. It's a boring reason, but it's the honest one, and it's the reason most contractors who specialize eventually land here.
Warranty Structure and Transferability
Both manufacturers back their siding with a written warranty, and both separate the substrate (the board itself) from the factory finish, which is standard practice across the fiber cement industry. Where warranties actually diverge is in the fine print: what voids coverage, how a claim is prorated over time, whether the warranty transfers to a new owner if you sell the home, and how labor cost for a warranty repair is handled versus material cost alone. We've spent years reading Hardie's warranty documents, walking homeowners through what's covered, and — when it's mattered — actually filing claims. We can't say the same about Allura's paperwork, and we're not going to install a product and represent its warranty to a customer with anything less than full confidence in what that document actually says.
| Factor | What to Ask About | Why It Matters in This Market |
|---|---|---|
| Substrate warranty | Length, whether it's prorated, and what voids it | Coastal humidity and UV are exactly the conditions that stress-test a warranty over decades |
| Finish warranty | Whether it's separate from the substrate warranty | Intense year-round Florida sun fades paint faster than most parts of the country |
| Transferability | Whether coverage passes to a new owner and any transfer fee or window | Florida's resale market means many owners won't be the ones who need the claim |
| Labor coverage | Whether warranty covers just materials or also reinstallation labor | Labor is usually the larger cost in any siding repair |
| Installer requirements | Whether coverage depends on using a certified or approved installer | Determines whether your contractor choice affects your own warranty standing |
Track Record on the Gulf Coast
Pinellas County siding doesn't get an easy life. It faces hurricane-force wind gusts, wind-driven rain that gets pushed sideways into wall assemblies, salt air drifting in off Tampa Bay and the Gulf, and some of the most consistent, intense UV exposure in the country. Fiber cement as a category handles that combination far better than vinyl or wood — it doesn't warp in heat, it doesn't get brittle and crack in wind-borne debris impacts the way vinyl can, and it doesn't feed the moisture-driven rot that untreated wood siding suffers here. Within that category, we've built our own track record specifically with Hardie product on homes across St. Petersburg and the surrounding Pinellas communities. We know how it ages here, what its failure points look like a decade in, and what maintenance actually keeps it looking new. That's institutional knowledge we don't have with Allura, and we're not willing to guess on a homeowner's largest exterior investment.
Installation Consistency and Local Code Documentation
Florida's wind-load building code requirements are not uniform paperwork — different jurisdictions and different exposure categories call for different fastening schedules and documented wind ratings. Because we install one manufacturer's product exclusively, our permitting submittals, our fastener schedules, and our inspector conversations are all built around one set of published technical documentation that we know cold. That reduces friction at permitting and inspection, which translates into fewer delays on your project. A crew that occasionally installs a second brand has to keep two sets of code documentation straight, and that's where paperwork mismatches and inspection delays tend to originate.
What This Means for Your Project
If a homeowner in St. Petersburg is comparing fiber cement quotes and one includes Allura, here's what we'd tell them to ask before signing anything:
- Ask for the manufacturer's written warranty document itself, not just a verbal summary of what it covers
- Ask whether the installer is factory-trained or certified on that specific manufacturer's product
- Ask what fastener type, spacing, and clearance-at-grade spec the installer is actually following, and whether it matches the manufacturer's published manual
- Ask whether the factory finish (if any) includes color-matched caulk and trim, or whether trim will be field-painted separately
- Ask how the product has performed on other homes in this specific climate, not in general marketing material
- Ask what happens if a warranty claim arises after the home is sold to a new owner
None of these questions are unique to Allura — they're the right questions for any fiber cement quote, from any manufacturer, from any contractor. We just happen to know our own answers to every one of them cold, because we've built our business around a single product system.
Cost Considerations
Fiber cement siding costs more than vinyl and generally lands in a similar broad range across reputable manufacturers, since the underlying material, labor intensity, and finish process are comparable. The real cost differences homeowners should weigh aren't between Hardie and Allura on a per-square-foot basis — they're in the long-run costs of warranty claims, finish touch-up availability, and whether your installer's crew is deeply practiced on the specific product going on your walls. A slightly lower material quote is a poor trade if it comes with an installer who is less familiar with that manufacturer's tolerances, in a climate that punishes installation mistakes faster than most.
Why We Put James Hardie on Homes Instead
None of this is a claim that Allura is defective or unsafe. It's a fiber cement product made by a real manufacturer, and other licensed contractors install it in good faith. Our decision to install James Hardie exclusively comes down to depth of knowledge: one factory finish system we understand completely, one climate-zoned product line built with the Gulf Coast in mind, one warranty document we can explain in plain English, and one installation manual our crews have followed for years of Pinellas County jobs. When wind gusts, salt air, and Florida sun are working against your siding for the next several decades, we'd rather bring specialization to that fight than a second product line we haven't fully lived with.
