Alpine Exteriors (FL license RB29003900) made a decision a long time ago that some homeowners find surprising when they first call us: we don't carry vinyl siding, we don't carry LP SmartSide, and we don't sell engineered wood panels. We install James Hardie fiber cement siding, full stop. That's not a marketing gimmick — it's what happens when you spend enough years re-siding homes in Pasco County and see what actually holds up against Gulf Coast humidity, afternoon storms, and salt-tinged air rolling in off the Pithlachascotee River corridor. Bayonet Point's mix of 1970s-through-90s block ranch homes, canal-front lots, and inland streets each present their own moisture challenges, and fiber cement is the one product category we're comfortable standing behind with a real warranty and our name on the invoice.
This page is specifically about the James Hardie brand — the product lineup, the ColorPlus factory-finish system, and what the 30-year warranty actually promises you as a homeowner. If you're comparing siding materials in general, that's a different conversation; here we're talking about why this one manufacturer earned an exclusive spot on our trucks.
James Hardie makes several distinct siding profiles, and part of doing this job right is matching the right one to your house rather than defaulting to whatever's easiest to install. In Bayonet Point we typically work with:
All of it is fiber cement — a mix of Portland cement, sand, and cellulose fiber pressed and cured into a dense, stable board. It doesn't expand and contract with humidity swings the way wood does, it doesn't support termites or wood rot, and it holds paint and factory finish far longer than wood-based alternatives. That stability matters more in a coastal Florida climate than almost anywhere else in the country.
Every James Hardie board can be installed primer-only and field-painted, but for most Bayonet Point homeowners we recommend ColorPlus Technology, which is Hardie's factory finishing process. Instead of a painter applying color on-site — where humidity, temperature, and application inconsistency all affect how long paint lasts — ColorPlus finishes are baked onto the board in a controlled factory environment using multiple coats and a UV-cured process.
What that means in practical terms for a house near the Gulf:
We still offer primed boards for homeowners who want a custom color mixed locally or who are matching an unusual HOA-approved palette, but for straightforward jobs, ColorPlus is the better long-term value, and it's what we default to when quoting.
James Hardie backs its fiber cement siding, soffit, and trim products with a 30-year, non-prorated limited warranty against manufacturing defects — meaning the substrate itself is warrantied not to crack, rot, or delaminate for three decades under normal conditions. That's a substrate warranty, separate from the finish. ColorPlus-finished products carry their own separate finish warranty, typically covering fade, chipping, and peeling of the factory coating for a defined term measured in years rather than months, layered on top of the substrate coverage.
Warranty terms are between you and the manufacturer, but installation quality is what determines whether a warranty claim ever gets denied. Improper flush-mounting, wrong fastener spacing, or skipping the required gap at grade are the kinds of installation errors that can void coverage — which is part of why we don't treat this as a side material we occasionally install. We follow Hardie's published installation specifications on every job.
| Coverage Element | What It Applies To | Typical Term |
|---|---|---|
| Substrate warranty | Cracking, rotting, or structural failure of the fiber cement board itself | 30 years, non-prorated |
| ColorPlus finish warranty | Peeling, chipping, or cracking of the factory-applied finish | Multi-year, separate from substrate term |
| Field-applied paint | Standard paint warranty from the paint manufacturer, not James Hardie | Varies by paint brand and applicator |
| Installation workmanship | Covered by Alpine Exteriors, not the manufacturer | Per our project contract |
Keep your closing paperwork and installer information on file — most warranty claims start with proof of who installed the product and when, which is one more reason to work with a licensed installer rather than a handyman crew.
Bayonet Point sits in unincorporated Pasco County along the Pithlachascotee River, with plenty of homes on canals feeding toward the Gulf and plenty more set back on inland streets closer to US-19. Either way, the climate doesn't care much about the distinction: high humidity nearly year-round, a wet season that runs roughly June through September, and a hurricane season that regularly sends wind-driven rain sideways into exterior walls. Homes closer to the water pick up salt air on top of that, which accelerates corrosion on fasteners and finishes that aren't rated for it.
James Hardie fiber cement is engineered specifically for climates like this. The HZ5 formulation used in Florida is designed to resist moisture absorption and the freeze isn't a factor here, but humidity cycling is — and that's exactly what fiber cement handles better than wood-based products, which swell, cup, and eventually rot when they take on repeated moisture. It also doesn't feed termites, a real consideration in older Bayonet Point neighborhoods where mature landscaping sits close to the house.
Wind resistance matters too. Properly installed with the correct fastener schedule, HardiePlank carries wind load ratings that hold up under Florida's building code requirements for our wind zone, which is one of the reasons we treat fastener spacing and nailing patterns as non-negotiable rather than a place to save time.
Fiber cement is an unforgiving material to install poorly. Unlike vinyl, which flexes and hides minor gaps, Hardie siding needs to be installed to spec or it will fail early — and that failure often isn't visible until moisture has already gotten behind the board. Before we start a Bayonet Point project, we walk through the same checklist on every house:
This is the difference between a siding job that earns its 30-year warranty and one that develops problems in year four. It's also why we tell homeowners to ask pointed questions before hiring anyone to install Hardie products, coastal Florida especially.
Every Bayonet Point home is different, so we don't quote off a flat per-square-foot number without seeing the house. The factors that actually move the price are worth understanding before you start collecting estimates:
| Cost Factor | Why It Matters |
|---|---|
| Existing siding removal | Tear-off of old wood, aluminum, or damaged siding adds labor and disposal cost versus installing over sound sheathing |
| Substrate and moisture damage | Rotted sheathing or water-damaged framing found during tear-off needs repair before new siding goes up |
| Profile and finish choice | ColorPlus-finished boards cost more upfront than primed boards but reduce repaint costs over the life of the siding |
| Home shape and trim detail | Multiple gables, dormers, and cut-in windows increase labor time versus a simple rectangular footprint |
| Access and site conditions | Canal-front lots, tight side yards, and mature landscaping can add setup and staging time |
We provide a written, itemized estimate before any work starts, and we walk you through exactly which James Hardie products and finish options make sense for your home and budget.
One of the real advantages of ColorPlus over field-painted siding is how little upkeep it needs. A rinse with a garden hose once or twice a year removes salt residue and pollen buildup — pressure washing isn't recommended and can damage the finish if the nozzle is held too close. Keep an eye on caulked joints and touch up with the manufacturer-matched ColorPlus repair kit if you notice a scuff, rather than reaching for a can of exterior paint that won't match the sheen or color exactly. Trim back shrubs and irrigation heads that spray directly on the siding, since constant wetting at the base of a wall is the most common cause of long-term problems on any siding material, fiber cement included.
If you're weighing James Hardie siding for a home near the river, a canal lot, or a street further inland, we're happy to walk the property, look at what's actually driving your current siding problems, and give you a straightforward estimate — no pressure, no upsell to a product we don't believe in. Reach out below and we'll set up a time to take a look.
Fiber cement is a cement, sand, and cellulose fiber composite pressed into boards, which makes it dimensionally stable in a way wood and some engineered products aren't. It resists moisture-driven swelling, doesn't feed termites, and holds a factory finish longer than field-painted materials. That stability is the main reason it performs well in humid, storm-prone climates like ours.
Ask for their Florida contractor license number and verify it's active through the state licensing lookup, and ask specifically about their experience with Hardie's fastener schedule, clearance requirements, and flashing details. A contractor who can't speak specifically to those installation details is a bigger risk with fiber cement than with more forgiving materials.
No — we only install James Hardie fiber cement siding. We made that decision based on how the material performs long-term in Gulf Coast conditions, and it's simpler for us to stand fully behind one manufacturer's product and warranty rather than juggle materials with different moisture and durability profiles.
HardiePlank is horizontal lap siding and covers the large majority of whole-house installs we do in Bayonet Point. HardieShingle mimics a cedar shake look and is more commonly used as an accent on a gable end or entry feature rather than the entire exterior, partly due to cost and partly for visual contrast.
Homes closer to the water deal with more salt air and moisture exposure, so we pay extra attention to fastener corrosion resistance and sealant choices on those properties. The siding material and warranty are the same either way, but installation details around flashing and clearance at grade get even more attention on waterfront lots.
