If you searched "vinyl siding contractor near me" and landed on this page, you deserve a straight answer before you call anyone: Alpine Exteriors (FL license RB29003900) does not install vinyl siding, and we don't plan to. Not because vinyl doesn't have its place in some markets, but because after years of exterior work on Pinellas County homes — from the bungalows off Edgewater Drive to the newer construction east of Alt 19 — we made a professional decision to install only James Hardie fiber cement siding. This page explains why, what that means for your Dunedin home specifically, and what to expect if you move forward with us instead.
Dunedin sits close enough to the Gulf that homes take a steady dose of intense, high-UV sun for most of the year. Vinyl siding is a petroleum-based product, and sustained heat and UV exposure are its two biggest long-term stressors. Over years, panels can warp, buckle, or fade unevenly — especially on south- and west-facing walls that catch the harshest afternoon sun. Fiber cement doesn't have that same relationship with heat; it's a cement, sand, and cellulose composite that holds its shape and color stability in ways a vinyl polymer product structurally can't match.
Pinellas County storm season runs roughly June through November, and Dunedin — sitting on a peninsula between St. Joseph Sound and Tampa Bay — sees its share of tropical moisture, gusty squalls, and the occasional direct hurricane threat. Vinyl siding is installed with a "hanging" method that allows the panels to expand and contract, which also means wind can get up under panel edges during sustained gusts, leading to panels popping loose or cracking on impact from wind-blown debris. Fiber cement is installed with a rigid, fastened method that holds up better against sustained wind loads and won't shatter the way brittle vinyl can in a cold snap or on storm-flung debris.
James Hardie engineers specific product lines for Gulf Coast humidity and salt air, which is exactly the environment Dunedin sits in. We use two of their product lines most often on local homes, depending on the house's style and the homeowner's goals.
This is the standard horizontal lap siding most homeowners picture when they think "siding job." It comes pre-primed or with factory-baked ColorPlus finish, holds a crisp shadow line, and is the right call for most ranch, colonial, and traditional Florida homes throughout Dunedin's residential neighborhoods.
Dunedin has a real concentration of early-1900s craftsman bungalows and Cracker-style homes, particularly near the historic downtown core. For homeowners restoring or maintaining that look, HardieShingle gives you a staggered, shingle-style fiber cement product that reads as traditional wood shingle from the street without the moisture problems that come with actual wood in a humid coastal climate.
Dunedin isn't uniform — homes right along the causeway or facing St. Joseph Sound deal with more direct salt spray and wind exposure than homes further inland near Highlander Park or the US 19 corridor. For siding closer to the water, we pay closer attention to fastener corrosion resistance and flashing details around windows and doors, since salt air accelerates corrosion on lower-grade hardware faster than most homeowners expect. Inland homes still deal with the same humidity and storm exposure, just with less direct salt load, so the core product choice doesn't change — the detailing around penetrations and trim does.
A lot of Dunedin's charm comes from its older, walkable neighborhoods and the golf-cart-friendly streets around downtown, where a lot of homes are 40, 60, even 100+ years old. When we're re-siding an older home, that usually means dealing with existing moisture damage behind old siding, non-square wall lines that need to be accounted for during layout, and — in some cases — proximity to the city's historic district guidelines, which can affect exterior appearance requirements. We walk homeowners through what applies to their specific address before work starts rather than assuming a one-size-fits-all approach.
Since you searched with vinyl in mind, it's worth being upfront about cost, because that's usually the real reason vinyl gets searched first. Here's an honest, broad comparison — actual numbers depend on your home's size, wall condition, and trim details, and we'll walk your specific job before quoting anything.
| Factor | Vinyl Siding | James Hardie Fiber Cement |
|---|---|---|
| Upfront material + install cost | Generally lower | Higher, reflects material and labor |
| Expected lifespan in Gulf Coast climate | Shorter, sun/heat dependent | Long-term, engineered for humid climates |
| Wind and impact performance | Can crack or blow loose in gusts | Rigid-fastened, holds up better in storms |
| Color and finish stability | Can fade or discolor with UV exposure | ColorPlus finish resists fading |
| Resale and appraisal perception | Viewed as a lower-cost upgrade | Often viewed as a premium, durable upgrade |
The honest trade-off: vinyl costs less to put up, fiber cement costs more but is built to handle the specific stresses — sun, salt air, wind — that this part of Florida throws at a house year after year.
Every job starts with a walk-around of the existing exterior to check for moisture damage behind current siding, soft sheathing, and any areas where flashing or trim needs attention before new siding goes up — covering that up instead of fixing it just hides a problem for the next owner. From there we handle removal, any needed sheathing or moisture-barrier repair, and installation per James Hardie's fastening and clearance specifications, which matter for warranty coverage and for how the siding performs in wind. We finish with proper caulking and trim work around windows, doors, and corners, since most siding failures start at those transition points rather than the field of the wall itself.
Whether you end up working with us or someone else, these are the questions worth asking before signing anything for siding work on a Dunedin home:
If a contractor can't answer these clearly, that's worth treating as a red flag regardless of the material being discussed.

Vinyl siding is still installed across Florida, but it performs less consistently in Gulf Coast conditions than in drier or cooler climates because of sustained heat, UV exposure, and storm-season wind. That's a big part of why some contractors, including us, have moved toward fiber cement as their standard product instead. It's a material trade-off, not a claim that vinyl is unsafe or against code.
Florida contractor licenses can be looked up through the state's Department of Business and Professional Regulation (DBPR) website using the license number the contractor provides. Any licensed contractor should give you that number without hesitation, and it's worth checking before signing a contract or paying a deposit. Alpine Exteriors' license number is RB29003900.
HardiePlank is horizontal lap siding, the more common look for traditional and ranch-style homes. HardieShingle mimics a staggered wood-shingle appearance and tends to suit older bungalow or craftsman-style homes, which are common in Dunedin's historic neighborhoods. Both are fiber cement, just different profiles for different architectural styles.
Hardie siding with a factory ColorPlus finish is baked on and typically holds color longer than field-applied paint, so it doesn't need repainting on the same schedule as wood siding. If a homeowner chooses primed siding instead and has it field-painted, that paint job follows a normal exterior paint maintenance schedule, generally every seven to ten years depending on sun exposure.
Homes within or near Dunedin's historic district or Community Redevelopment Area may have exterior appearance guidelines that affect material choice or appearance, depending on the specific address. We check whether a property falls under any local design review before finalizing a siding plan, so it's worth mentioning your address early in the conversation if you're unsure.
