When Northdale homeowners search "siding company near me," they usually get a list of general contractors who install whatever's on sale that month — vinyl one week, an engineered wood product the next. Alpine Exteriors works differently. We install James Hardie fiber cement siding, exclusively. Not because it's the only product on the market, but because after years of crawling under Hillsborough County homes and tearing off failed siding jobs, it's the only product we're willing to put our name and our license (FL RB29003900) behind.
That focus matters more in Northdale than in a lot of places. This is a mature, tree-canopied community off Dale Mabry near the Northdale Golf and Tennis Club, built mostly through the late 1970s and 1980s. A lot of the original siding and trim on these homes is thirty, forty, even fifty years old. When it's time to replace it, homeowners here aren't just picking a color — they're deciding what their house will be wrapped in for the next several decades of Tampa Bay summers.
We get asked constantly why we don't offer cheaper alternatives. Here's the honest answer, not a sales pitch.
Vinyl is inexpensive and easy to install fast, which is exactly why so many contractors default to it. But it's a thin plastic product that expands and contracts with heat — and inland communities like Northdale, tucked away from any sea breeze, regularly see attic and wall-cavity temperatures climb well past what coastal properties experience. Over time that constant expansion and contraction warps panels, pops fasteners, and fades color unevenly on the sun-exposed sides of a house. It also doesn't hold paint, so once it fades, your only fix is replacement.
Engineered wood products use wood strand technology with resin binders. It looks good on day one, but any breach in the factory coating or caulking — a nail pop, a hairline seam gap, a woodpecker hole — lets moisture into the substrate. In Florida's humidity, that moisture doesn't dry out fast, and wood-based products swell, delaminate, or rot from the inside before you'd ever notice from the curb. We've torn enough of it off Hillsborough County homes to know it's not a product we want to stand behind here.
James Hardie siding is roughly 90% sand, cement, and cellulose fiber. It doesn't expand and contract the way vinyl does, it doesn't feed mold or rot the way wood does, and it holds a factory finish (ColorPlus Technology) far longer than field-applied paint on other materials. It's also engineered specifically for humid, high-heat climates — Hardie makes a dedicated HZ10 product line formulated for exactly the conditions Tampa Bay throws at a house.
We work throughout unincorporated Hillsborough County, including Northdale, Carrollwood, Cheval, Lutz, and the surrounding Dale Mabry corridor. Being local isn't just a marketing line — it means our crews already know Northdale's neighborhood-specific quirks:
Northdale sits inland, away from the direct coastal storm surge zones to the west, but it's still squarely inside Hillsborough County's wind-borne debris region. That means siding here still has to meet Florida Building Code wind-load requirements, and it still takes a beating from the horizontal, wind-driven rain that comes through during a typical June-through-November storm season — not just from named storms, but from the daily summer thunderstorm pattern this whole area lives with.
A siding job is only as good as the details underneath it — the parts you never see again once the new boards are up. Here's how we run every project.
We walk the exterior with you, check for soft spots, water staining, or rot in the sheathing, and talk through what we're seeing. This is also when we discuss HOA approval needs if you're in a Northdale deed-restricted section.
James Hardie offers several siding profiles — lap siding in varying reveal widths, board-and-batten vertical siding, and Hardie Shingle for accent areas. We'll walk you through which profile fits your home's architecture and your neighborhood's character, along with ColorPlus factory-finish color options.
We remove the existing siding down to the sheathing and inspect for moisture damage or rot. Any compromised sheathing gets repaired or replaced before a single new board goes up — this is the step corners get cut on, and it's the step that determines whether siding lasts 10 years or 40.
A properly installed weather-resistant barrier and correctly flashed windows, doors, and penetrations go on next. This is the moisture-management layer that actually protects your home; the siding itself is really the second line of defense, not the first.
Installed to James Hardie's published fastening, clearance, and caulking specifications — proper nail placement, correct gapping at seams, and ground clearance to keep the bottom edge away from standing moisture and irrigation overspray.
We walk the finished job with you, check every elevation, and address anything before we call it complete.
| Factor | James Hardie Fiber Cement | Vinyl | Engineered Wood |
|---|---|---|---|
| Heat/humidity performance | Formulated for Florida climate (HZ10) | Expands, warps, fades in heat | Vulnerable to moisture intrusion |
| Finish durability | Factory ColorPlus finish, long-lasting | Color fades, cannot be repainted easily | Coating breach leads to swelling |
| Fire resistance | Non-combustible core material | Melts/deforms under heat | Combustible wood-based core |
| Wind/impact durability | Rated for high wind zones | Can crack or blow off in high wind | Denting and edge damage over time |
| Long-term maintenance | Low — occasional wash and caulk check | Low, but limited repair options | Higher — moisture and pest monitoring |
Every Northdale home is different, so we don't quote prices sight-unseen. What actually moves the number:
We give you a written, itemized estimate before any work begins, so there are no surprise line items halfway through the job.
James Hardie backs its fiber cement siding products with a limited transferable product warranty (30 years on most HardiePlank and HardiePanel products) and a separate finish warranty on ColorPlus factory-applied color. Because we're a Hardie-focused installer, we install strictly to their published specifications — which matters, because improper installation is one of the most common reasons warranty claims get denied industry-wide. We also stand behind our own workmanship separately from the manufacturer's product warranty, and we'll walk you through exactly what's covered, and for how long, before you sign anything.
Most Northdale siding jobs run from about a week to several weeks depending on square footage and how much substrate repair is needed. During that window, expect a work crew on-site during daytime hours, dumpster or debris staging in your driveway, and daily cleanup at the end of each shift — especially important with the mature tree canopy common throughout this neighborhood. We'll walk you through the schedule up front so you know what each phase of the job looks like before it starts.
If your Northdale home's siding is original, cracking, or you're just tired of vinyl that's warped in the Florida heat, we'll come take a look and give you a straight, no-pressure estimate. Use the form below to get started.
A company focused on one product line knows its fastening specs, flashing details, and warranty requirements cold, rather than switching methods between different materials. That specialization is exactly why we install James Hardie exclusively rather than offering several product lines.
Ask for their Florida license number, proof of insurance, and whether they pull permits through Hillsborough County themselves. Also ask what happens if they find rotted sheathing during tear-off — a contractor who can't answer that clearly hasn't done many real jobs.
HardiePlank is horizontal lap siding, the most common look on traditional homes, available in several reveal widths. HardiePanel is a vertical sheet product often used for board-and-batten styling or as an accent alongside lap siding.
Not if you choose a ColorPlus factory-finished product — the color is baked on at the factory and typically holds up far longer than field-applied paint. If you ever do want a color change down the road, Hardie siding can be repainted using standard exterior paint.
Northdale isn't in a direct storm surge zone, but it's still inside Hillsborough County's wind-borne debris region, so siding still needs to meet Florida Building Code wind-load standards. The bigger factor here is heat and humidity from the tree-shaded, inland microclimate, which is part of why we install a product formulated for exactly those conditions.
