Walk any street between Hillsborough Avenue and the river in Old Seminole Heights and you'll see it: bungalows and Craftsman-style homes from the 1920s and '30s, many still wearing their original wood lap siding, or a repaint-after-repaint version of it. That siding is part of what makes this neighborhood look like nowhere else in Tampa. It's also, in a lot of cases, quietly falling apart under the paint.
We get calls from Old Seminole Heights homeowners every storm season who assumed their siding just needed a fresh coat of paint, only to find soft, spongy boards, hidden rot at the bottom courses, or termite galleries running behind the trim once we pull a board loose. This page is about that specific situation: what's actually happening to wood siding in this neighborhood, and why our answer, every time, is James Hardie fiber cement rather than more wood.
Old Seminole Heights isn't a beachfront neighborhood, but "inland" doesn't mean "dry." Hillsborough County sits in a humid subtropical climate, and this particular neighborhood has a feature that makes moisture problems worse for wood: its mature tree canopy. The live oaks that give these streets their shade also block sun and airflow from reaching exterior walls. Wood siding needs to dry out between rain events to survive long-term. Under heavy shade, north-facing walls and sections tucked behind foundation plantings can stay damp for days after a summer storm.
Add in Tampa's long, wet season from June through September, near-daily humidity above 60%, and a healthy termite population that thrives in exactly these conditions, and you have a climate that is genuinely hard on real wood siding. This isn't a knock on the material in the abstract — cedar and cypress lap siding was a reasonable choice for a 1920s builder. It's a statement about what a century of Tampa Bay humidity, subsequent repaints, and inconsistent maintenance does to that material over time.
When a homeowner asks us to replace failing wood siding with more wood, we're honest about why we don't offer that. It isn't that wood can't be installed correctly — it's that in this climate, with this canopy coverage, wood siding puts the maintenance burden back on the homeowner almost immediately. Paint failure typically starts within a few years here, not the decade-plus you'd get in a drier climate, and once paint fails, moisture gets in and the clock on rot starts again.
James Hardie fiber cement siding is cement, sand, and cellulose fiber, engineered specifically for climates like ours. It doesn't rot, it isn't a food source for termites, and it holds paint and factory-applied ColorPlus finishes far longer than wood under the same humidity and shade conditions. For a neighborhood where the whole point is preserving a certain look without redoing the work every few years, that's the trade-off we think matters most.
The sticker price on wood siding repair or replacement is rarely the real cost. The real cost is what happens over the following 5, 10, and 20 years: repainting every 3-5 years in this humidity, spot-replacing rotted boards, re-caulking joints, and eventually discovering that termite or moisture damage has spread into the sheathing behind the siding. We've opened up enough Old Seminole Heights walls to know that a "small repair" often isn't small once the siding comes off.
We're not asking Old Seminole Heights homeowners to give up the character that makes their block recognizable. HardiePlank lap siding is manufactured with a wood-grain or smooth finish and standard reveal widths that read as traditional lap siding from the curb. HardieShingle panels replicate the staggered cedar-shake look you'll see on some of the neighborhood's bungalow gables and accent areas. Combined with proper trim, corner boards, and a factory ColorPlus finish matched to period-appropriate colors, the result reads as "well-maintained historic siding," not "obviously modern replacement."
This neighborhood has real design consistency: low-pitched gable roofs, deep porches, exposed rafter tails, and horizontal lap siding with visible reveal lines that catch shadow in a particular way. When we plan a siding replacement here, we measure the existing reveal and match it, keep corner board and trim dimensions consistent with the original detailing, and select a HardiePlank profile and color that sits naturally next to unpainted brick chimneys and porch piers common in the area. The goal is a house that still looks like it belongs on the block, not a house that suddenly looks like it was built in a different decade.
| Factor | Traditional Wood Siding | James Hardie Fiber Cement |
|---|---|---|
| Rot resistance in shaded, humid areas | Poor — moisture absorption drives decay | Excellent — cement-based, does not absorb and rot |
| Termite vulnerability | High, especially at ground-contact boards | Not a food source for termites |
| Repaint interval in Tampa Bay humidity | Often every 3-5 years | Factory ColorPlus finish typically holds 15+ years |
| Storm and wind-driven rain performance | Depends heavily on installation and upkeep | Engineered and tested for high-wind, wet climates |
| Historic appearance options | Authentic, but high upkeep to maintain look | Lap, shingle, and board-and-batten profiles replicate the look |
Hillsborough County sees its share of tropical storm activity, and even when a system doesn't make a direct hit, Old Seminole Heights gets the wind-driven rain and gusty outer bands. Siding that's already compromised by rot or loose boards is exactly what tends to fail first — a board that's already soft doesn't hold fasteners well, and gaps that let water behind the siding during a normal afternoon storm become a real problem during a named storm. James Hardie siding is manufactured and tested for high-wind, high-moisture climates like Florida's, which matters more here than in most parts of the country.
We start with a full inspection of the existing wood siding and the sheathing behind it, since that's where the real condition of the wall shows up. From there:
Every wood siding replacement in Old Seminole Heights prices out a little differently based on what we find once the old siding comes off. The main cost factors are the square footage and stories involved, how much sheathing or framing repair is needed behind the wood (which we won't know for certain until we open the wall), the trim and corner detailing required to match historic profiles, and the specific James Hardie product line and finish you choose. Homes with more shaded, humidity-heavy sides of the house often need more underlying repair than the sun-exposed sides, which is something we flag during the inspection rather than after the fact.
If your wood siding is showing its age, or you just want an honest look at what's really going on behind the paint, we're glad to come out and take a look. Fill out the form below for a free, no-pressure estimate.
Fiber cement is denser and more impact-resistant than most wood siding, and unlike wood, it doesn't lose strength as it absorbs moisture over time. It also holds up better to wind-driven debris during storms, which matters in Hillsborough County's tropical storm season.
Ask whether they'll inspect the sheathing behind the siding before quoting a price, since hidden rot or termite damage changes the scope. Also ask how they'll match your home's existing reveal width and trim detailing, since a mismatch is what makes replacement siding look out of place on a historic block.
We've standardized on James Hardie because of its manufacturing consistency, its ColorPlus factory finish warranty, and the range of profiles available for matching older architectural styles. Sticking with one manufacturer also means our crews install it the same way every time, which matters for long-term performance.
HardiePlank lap siding replicates traditional horizontal wood boards and is what most Old Seminole Heights homes originally had on their main walls. HardieShingle panels mimic staggered cedar shakes and are often used as an accent on gables or porch areas, which is a detail you'll see on some of the neighborhood's Craftsman-style bungalows.
Portions of Old Seminole Heights fall within local historic district designations that can carry exterior appearance guidelines, so it's worth checking with the City of Tampa before starting a project. We can work with those guidelines by matching reveal, trim, and color to your home's existing character.
