A lot of homeowners who call us about siding start the conversation asking about wood. It makes sense — cedar, cypress, and other traditional wood siding have a warmth and texture that's hard to argue with, and Oldsmar's mix of older lake-and-bay-adjacent homes and newer construction near Tampa Road and East Lake means plenty of houses were originally built with wood trim or wood-look siding decades ago. We get why the look appeals to people here.
But we're going to be straight with you before you spend a dollar: Alpine Exteriors does not install traditional wood siding, and we don't install vinyl or engineered wood products like LP SmartSide either. We install James Hardie fiber cement siding exclusively. This page walks through why — specifically for Oldsmar's climate, not as a generic pitch — and how you can get a wood-grain look without the problems wood brings to this part of Florida.
Oldsmar sits right on Old Tampa Bay, straddling the Pinellas-Hillsborough line, with a mix of waterfront canal homes, inland neighborhoods around Forest Lakes and East Lake, and everything in between. Whether a house is a hundred yards from the water or a mile inland off Race Track Road, it's dealing with the same basic climate reality: high year-round humidity, a wet season that dumps heavy rain from June through September, and a hurricane season that runs June to November with the Gulf close enough to matter.
Wood siding is a natural material, and natural materials move with moisture — they swell, they shrink, they cup and crack as they dry unevenly. In a climate that rarely gives wood a long stretch to fully dry out, that cycle repeats constantly. Add wind-driven rain during tropical systems, which pushes water into seams and butt joints that would stay dry in a drier climate, and you've got a siding material working against the conditions it's mounted in rather than with them.
Properly maintained wood siding can look great. The word doing the heavy lifting there is "maintained." In Tampa Bay's humidity, that typically means repainting or restaining every 3-5 years instead of the 7-10 you might get in a drier climate, plus regular caulking of joints, inspection for soft spots, and prompt repair of any board that starts to rot before it spreads to its neighbors. That's a real, recurring cost and a real time commitment — not a one-time upgrade.
This is the piece that catches people off guard. Pinellas and Hillsborough counties have significant pressure from subterranean termites, and the Tampa Bay area is one of the regions in Florida where Formosan termites — a more aggressive, harder-to-control species — have established colonies. Wood siding, especially where it's in ground contact or close to grade near foundation plantings (common in older Oldsmar lots), gives these insects a direct route into a home's structure.
Fiber cement contains no cellulose. Termites have no reason to touch it. That's not a marketing claim about a competitor's product being "garbage" — it's a straightforward material fact, and in a county with this much termite activity, it's one of the more practical reasons homeowners here move away from wood once they understand the risk.
James Hardie engineers its siding in regional formulations, and the product line used in Florida — HardieZone HZ5 — is specifically formulated for high-humidity, high-moisture climates like ours. It's a mix of cement, sand, and cellulose fiber, fired and cured into a rigid board that doesn't absorb water the way wood does, doesn't warp with humidity swings, and holds factory-applied ColorPlus finishes far longer than a field-applied paint job on wood ever will.
For homeowners who specifically want the wood look, HardiePlank's Cedarmill texture reproduces a cedar wood-grain surface, and the Select Cedarmill and Smooth options give you the choice between a subtle woodgrain texture or a clean, contemporary flat profile. Board widths and reveals mimic traditional lap siding proportions, so from the street it reads as siding, not as a fiber cement substitute — while underneath it's a completely different, better-suited material for this climate.
| Factor | Traditional Wood Siding | James Hardie Fiber Cement |
|---|---|---|
| Moisture response in Gulf Coast humidity | Swells, cups, and cracks with repeated wet/dry cycles | Engineered for HZ5 humidity zone; dimensionally stable |
| Termite vulnerability | High — active risk in Pinellas/Hillsborough termite zones | None — no cellulose for termites to feed on |
| Repaint/refinish cycle | Every 3-5 years in this climate | ColorPlus finish typically holds 15+ years |
| Wind-driven rain performance | Vulnerable at joints and seams during tropical storms | Installed with rain-screen detailing built for storm exposure |
| Impact/wind resistance | Varies widely by species and thickness | Rated for high-wind zones common along the Gulf Coast |
| Fire resistance | Combustible | Noncombustible core material |
| Upfront cost | Often lower per square foot for basic wood species | Higher upfront, lower lifetime cost given maintenance cycle |
Oldsmar isn't a barrier island community, but it's not sheltered from tropical systems either — Old Tampa Bay funnels storm surge and wind up the bay, and homes here have seen their share of downed trees and wind-driven rain events during the June-through-November season. Siding needs to do two jobs during a storm: stay attached under wind load, and keep water from wicking behind the cladding once the wind starts driving rain sideways.
We install James Hardie products with fastening patterns and flashing details built around Florida Building Code wind requirements for this region, along with proper weather-resistant barrier and drainage plane behind the siding — not just decorative surface material nailed to sheathing. That drainage detail matters as much as the siding itself when a system has to shed water during a multi-day tropical rain event rather than a typical afternoon shower.
Homes closer to Old Tampa Bay and the canal neighborhoods deal with more salt-laden air and direct storm exposure; homes further inland toward East Lake and the Hillsborough line get somewhat more tree cover and wind buffering but still see the same humidity and rainfall totals. Either way, the moisture-driven case against wood siding holds across the whole city — it's a difference of degree, not of whether the risk exists.
If the reason you were drawn to wood siding is the look rather than the material itself, that's the easiest part of this conversation. HardiePlank's woodgrain texture, paired with a ColorPlus finish in a warm cedar-adjacent tone, reads as a natural wood exterior from curb distance. Trim details, shutter placement, and board reveal width do more to create that "wood siding" character than the actual substrate does. We can walk you through the texture and color options side by side so you can see how close the match is before committing to anything.
Most of the homeowners we talk to who start out asking about wood siding aren't attached to wood as a material — they're attached to a look, or to what siding on Florida homes "used to be." Once they understand what subterranean and Formosan termites do to wood siding in this county, and what a five-year repaint cycle actually costs over a decade of ownership compared to a Hardie ColorPlus finish, the decision tends to make itself. We'd rather have that conversation honestly up front than sell a product we know won't hold up here.
If you're weighing your options for a home in Oldsmar — whether it's a canal-front property near the bay or a house further inland toward East Lake — we're happy to come take a look, talk through what your current siding is doing, and give you a straightforward estimate for a James Hardie installation built for this climate. No pressure, no upsell — just an honest look at what makes sense for your house.
No, we install James Hardie fiber cement exclusively and don't offer traditional wood, vinyl, or engineered wood products like LP SmartSide. We can match the wood-grain look homeowners want using Hardie's Cedarmill texture and color finishes.
Ask for their Florida contractor license number and verify it directly through the Florida DBPR license lookup, and confirm they're pulling permits through Pinellas County rather than working without them. Alpine Exteriors is licensed under Florida RB29003900, and we're glad to have that verified before any work starts.
HardieZone HZ5 is engineered specifically for high-humidity, high-moisture climates, with a formulation and finish system built to handle the moisture cycling common in Gulf Coast weather. It's the zone rating used across the Tampa Bay area, including Oldsmar.
Yes — Pinellas and Hillsborough counties both see significant subterranean termite activity, and the Tampa Bay region is one of the areas in Florida where Formosan termites have established colonies. Wood siding near grade or foundation plantings is a common entry point, which fiber cement eliminates since it contains no cellulose.
When installed with proper flashing, a drainage plane, and fastening patterns matched to Florida Building Code wind requirements, James Hardie siding is built to shed wind-driven rain rather than trap it behind the cladding. That installation detail matters as much as the siding material itself during a multi-day storm event.
