Oldsmar sits on the northwest shore of Old Tampa Bay, where Mobbly Bayou, Canal Street, and the R.E. Olds Park waterfront put a lot of homes within a stone's throw of brackish water. Head a few blocks inland toward Tampa Road, East Lake Woodlands, or Forest Lakes, and the humidity is still constant even if the salt air backs off. Either way, siding here works harder than siding in most of the country. That's the reason Alpine Exteriors installs one product line for every siding job we take in Oldsmar: James Hardie fiber cement. We don't offer vinyl, we don't offer LP SmartSide or other engineered wood panels, and we're not going to pitch you on them. This page explains why, what that actually means for your house, and what to expect if you're ready to move forward.
Pinellas County sees a long, humid summer, a wet season that runs roughly June through November, and the occasional direct hit or near-miss from a tropical system. Homes closer to the bay — along Canal Street, around Mobbly Bayou Preserve, or near the marina — deal with salt-laden air on top of that moisture. Homes farther inland, in neighborhoods like East Lake Woodlands or the older sections near State Street and downtown Oldsmar, get less salt exposure but still sit under near-constant humidity nine months a year.
That combination is hard on building materials that aren't engineered for it. Wood-based siding absorbs moisture and expands and contracts with it, which eventually shows up as swelling, cupping, or rot at seams and butt joints. Vinyl siding holds up to moisture fine on its own, but it softens and can warp in direct summer sun, and in a storm it's rated for wind speeds that don't always match what a real Gulf-fed system can throw at a house. Fiber cement doesn't have either problem — it's not organic, so it doesn't rot, and it's dense enough to hold its shape and its wind rating in real Florida weather.
We get asked this on almost every estimate, because vinyl is cheaper up front and it's what a lot of Oldsmar homes already have. Here's the honest version, not a sales pitch:
We're not saying every vinyl or engineered wood installation fails — plenty hold up fine for years under normal conditions. We're saying that when we put our name and our license on a job in a climate like this one, fiber cement is the standard we're willing to stand behind.
James Hardie makes several fiber cement profiles, and which one fits your house depends on its architecture and your preference. We install:
| Product | Look | Best fit |
|---|---|---|
| HardiePlank lap siding | Traditional horizontal lap, smooth or cedar-textured | Ranch and traditional homes throughout Oldsmar's older neighborhoods |
| HardieShingle | Staggered or straight-edge shingle panels | Coastal cottage and accent-gable looks near the bayfront |
| HardiePanel vertical siding | Smooth or stucco-textured vertical panels | Modern builds and accent walls, garages, gable ends |
| HardieTrim boards | Fascia, corner boards, window and door trim | Finishing detail on every job, matched to the siding profile |
All of it comes through Hardie's ColorPlus finishing system when you choose a factory color, which bakes the color into the board and backs it with its own warranty against fading and peeling — a real advantage in a market that gets this much direct summer sun.
A full siding replacement is a bigger job than most homeowners expect, and doing it right in a humid, storm-prone climate means the details under the siding matter as much as the siding itself. Our process:
Every house is different, and we'll give you a firm number after walking your property, but these are the main factors that move the price:
| Factor | Why it matters |
|---|---|
| Home size and wall area | More square footage means more material and labor hours |
| Existing siding removal | Tear-off and disposal of old vinyl, wood, or aluminum siding adds time |
| Sheathing or framing repair | Rot or water damage found underneath has to be fixed before new siding goes up |
| Siding profile and finish | Lap, shingle, and panel styles vary in material cost; factory ColorPlus finish costs more than field-painted |
| Architectural detail | Gables, dormers, and multiple roof lines mean more cuts, trim, and labor |
| Story height | Two-story sections require more scaffolding and staging time |
We give you a broad, honest range up front and a firm written quote after the walkthrough — no surprise add-ons once work starts unless we uncover hidden damage, and if that happens, we stop and talk to you before proceeding.
We install siding across Oldsmar, from the older homes near downtown and State Street to the canal and bayfront properties around Mobbly Bayou Preserve, and out to the newer construction and larger lots around East Lake Woodlands and the Tampa Road corridor. Coastal-adjacent homes tend to need closer attention to fastener corrosion resistance and flashing detail because of salt exposure; inland homes more often show up needing full replacement because the original wood or vinyl siding simply reached the end of its service life under years of Florida humidity. We treat each differently based on what your house and your lot actually need — not a one-size-fits-all package.
One of the practical reasons homeowners move to fiber cement is how little it asks of you afterward. A rinse with a garden hose once or twice a year to clear pollen, salt residue, and grime is usually all it needs. Caulked joints and trim should get a visual check each storm season, same as any exterior. James Hardie backs its boards with a 30-year limited product warranty, and ColorPlus finishes carry their own separate finish warranty — details we'll walk you through in writing before the job starts, not after.
If your Oldsmar home has siding that's cracking, rotting, holding moisture, or just past its service life, we're happy to take a look and give you a straight assessment — no pressure, no obligation. Fill out the form below and we'll set up a free estimate.
We standardized on James Hardie because it's the fiber cement product with the strongest track record in Gulf Coast humidity and storm conditions. Offering multiple lower-cost materials means standing behind products we don't think perform as well here, which isn't a trade-off we're willing to make.
Ask for their Florida contractor license number and verify it directly on the DBPR website, and confirm they carry current liability insurance and workers' comp coverage. A legitimate contractor will give you this information without hesitation before any work starts.
Yes — James Hardie manufactures the fiber cement boards and trim, and independent contractors like Alpine Exteriors handle sales, measurement, and installation. Hardie certifies installers who meet its training standards, but the installation quality still comes down to the crew doing the work.
HardiePlank gives you the traditional horizontal lap look and is the most common choice for full-house siding, while HardieShingle mimics a staggered or straight-edge shingle pattern often used as an accent on gables or coastal-style homes. Both use the same fiber cement material, so the choice comes down to the architectural look you want.
Homes closer to the bay and canals benefit from corrosion-resistant fasteners and careful flashing at every window and door to manage the added salt and moisture exposure. We assess this on-site since it varies significantly between a bayfront lot and a home a mile or two inland.
