Most siding companies in Pinellas County will sell you whatever's cheapest to install: vinyl, LP SmartSide, maybe an engineered wood panel if you ask nicely. We don't. Alpine Exteriors installs James Hardie fiber cement siding exclusively, on every home we side in Seminole, Largo, and the surrounding Tampa Bay area. That's not a marketing angle — it's a decision we made because Seminole's climate is genuinely hard on exterior materials, and we got tired of watching homeowners replace cheaper siding every 10-15 years while the house next door, sided in fiber cement, just sat there looking fine.
This page isn't a general "what is siding" overview. It's about how we actually run a siding job in Seminole: what our process looks like from first call to final walkthrough, what our warranty covers, where we work, and what you should expect if you call us. If you're comparing siding companies, this is the information that actually matters once you've decided fiber cement is the right call.
Seminole sits close enough to the Gulf that salt air, humidity, and wind-driven rain are part of daily life for a house's exterior — even a few miles inland, the moisture load here is higher than most of the country deals with. Vinyl siding softens and warps in sustained heat, and Florida summers deliver plenty of that. Engineered wood products rely on factory sealing and precise installation to keep moisture out of the substrate; one bad seam or a nail driven wrong, and you've got a slow-motion rot problem hiding behind the wall.
James Hardie fiber cement is cement, sand, and cellulose fiber — it doesn't warp in heat, it doesn't feed mold or insects, and it holds paint and color far longer than vinyl ever will. It's also rated for high-wind regions, which matters directly here: Pinellas County sits in a wind-borne debris zone, and Hardie's ColorPlus and HardieZone system products are engineered and tested for exactly this kind of exposure. We install it because it's the one material we can put behind our own workmanship warranty without reservations.
Seminole is a mix of established mid-century block homes near Seminole Lake and Park Boulevard, newer construction closer to the Pinellas Trail, and homes just a short drive from the barrier islands — Indian Rocks Beach, Madeira Beach, Redington Shores. The closer you are to the water, the more salt exposure your siding takes, and the more that decision compounds over 20-30 years. We size the product line — panel thickness, fastening pattern, flashing detail — to where your house actually sits, not a one-size-fits-all spec.
| Stage | What Happens | What You Should Expect |
|---|---|---|
| Initial estimate | On-site walk-around, measurements, discussion of trim/color/product line | No pressure, no inflated "today only" pricing tactics |
| Proposal | Written scope, materials list, timeline, and cost broken down by line item | You know exactly what's being installed and why |
| Prep | Removal of old siding, inspection of sheathing and framing for hidden damage | We stop and talk to you before covering up anything we find |
| Weather barrier & flashing | House wrap, window/door flashing, and drainage plane installed per Hardie spec | This step is invisible once done — and the one most corners get cut on elsewhere |
| Siding installation | Panels installed to Hardie's fastening and clearance specs | Correct nailing pattern, proper gaps at grade and trim, caulking done right |
| Finish & walkthrough | Trim, caulking, cleanup, final inspection with you present | A walkthrough where we point out details, not just a wave goodbye |
The step homeowners underestimate is the weather barrier and flashing work. Siding is the visible layer, but the drainage plane behind it is what actually keeps water out of your walls over 20+ years. We follow Hardie's published installation instructions to the letter here — proper clearances at rooflines, decks, and grade, correct flashing above windows and doors — because that's what keeps a manufacturer warranty valid and, more importantly, what keeps your walls dry.
Florida's storm season runs roughly June through November, and we plan around it. If a job is scheduled during that window, we track forecasts and sequence work to avoid leaving a home with exposed sheathing ahead of a named storm. That's a scheduling discipline, not a guarantee we control the weather — but it's part of how we protect your home during the project itself.
There are two separate warranties on a Hardie siding job, and homeowners deserve to understand both before signing anything.
Hardie backs its fiber cement products with a non-prorated limited warranty on the material itself — the specific term depends on the product line (lap siding, panels, trim) and whether it's factory-primed or ColorPlus prefinished. ColorPlus finishes carry their own separate finish warranty covering color retention and coating performance. We'll walk you through the exact terms for the product line we're proposing for your home, in writing, before work starts.
Materials are only half the equation — the other half is installation. Most siding failures we get called out to inspect on other companies' work trace back to installation error, not product failure: wrong fastening pattern, missing flashing, siding installed too close to grade or roofline. We stand behind our own labor separately from the manufacturer's material warranty, because a homeowner shouldn't have to guess whether a problem is ours or Hardie's to fix.
Based in the Tampa Bay area, we regularly work throughout Seminole, Largo, unincorporated Pinellas County, and the surrounding communities out toward the beaches. We hold Florida license RB29003900, which covers residential building contracting work including siding installation across the state. If you're just outside what you'd consider "Seminole proper" — closer to Bardmoor, Ridgecrest, or the Walsingham corridor — we're still covering that territory. Ask when you call.
| Factor | Why It Matters |
|---|---|
| Home size and wall complexity | More square footage and more corners/dormers means more cutting, flashing, and labor |
| Removal scope | Stripping old siding down to sheathing costs more than installing over a sound existing surface (when code and condition allow) |
| Substrate condition | Rotted sheathing or old framing damage found mid-job adds repair cost before siding can go on |
| Product line and finish | Factory-primed vs. ColorPlus prefinished panels, plank profile vs. panel siding |
| Trim and architectural detail | Board-and-batten accents, extra trim widths, and shutters add labor time |
We don't quote a per-square-foot number over the phone, because the honest answer depends on what's actually on your walls right now. That's what the on-site estimate is for.
If you're seeing any of this, it's worth a look before it becomes a bigger repair. We can often tell from the outside whether it's cosmetic or something that's already gotten into the wall assembly.
We're not the cheapest bid you'll get, because we're not installing the cheapest material. What we offer instead is a single-product focus that lets us actually know what we're doing — one installation spec, one set of manufacturer requirements, one warranty structure to explain clearly instead of juggling five different products with five different failure points. For a coastal-adjacent climate like Seminole's, that focus is the whole value proposition.
If you're ready to talk through your home specifically — product line, timeline, and a real number — we'd rather walk your property and give you a straight answer than guess over the phone. Reach out for a free, no-pressure estimate using the form below.
We standardized on one product because it lets us install it correctly every time and back it with a real workmanship warranty. Vinyl and engineered wood have failure modes — heat warping, moisture intrusion at seams — that are common in Florida's climate, and we'd rather not sell something we don't fully stand behind.
You can look up any Florida contractor's license number on the DBPR (Department of Business and Professional Regulation) website to confirm it's active and see if there's disciplinary history. Ours is RB29003900 — ask any contractor for theirs before signing anything, and be cautious of anyone who won't provide it.
Factory-primed siding needs to be field-painted after installation, giving you full color flexibility but adding a painting step and cost. ColorPlus comes with a baked-on finish applied at the factory under controlled conditions, which typically holds color longer than field-applied paint and carries its own separate finish warranty.
Fiber cement itself doesn't corrode or rot from salt exposure the way some materials can, but it still benefits from periodic rinsing to clear salt residue and dust buildup. Caulking and paint film (on factory-primed product) should be checked periodically, since those are the components most affected by sustained coastal exposure.
For most single-family homes it runs anywhere from several days to a couple of weeks, depending on square footage, how much old material needs to come off, and whether we find substrate repairs once the old siding is removed. We give you a realistic timeline upfront during the estimate, not just a best-case number.
