Siding Installation for Historic Kenwood's Older Housing Stock
Historic Kenwood is one of St. Petersburg's older residential neighborhoods, and that history shows up in the framing behind the walls as much as it does in the porch details out front. Homes built decades ago were sided for a different era of expectations — original wood siding, later replaced in some cases with vinyl or older fiber cement, was never engineered for the intensity of Gulf Coast weather we see today. When we install siding in Historic Kenwood, we're not just swapping one material for another. We're accounting for original wall framing, uneven historic dimensions, and the reality that a home in this part of Pinellas County takes a beating from sun, salt, and storms every single year.
This page covers what a correct siding installation looks like specifically for Historic Kenwood homes — not siding installation in general, but the version of it that holds up on these streets.

What St. Petersburg's Climate Actually Does to Siding
St. Petersburg sits on a peninsula, and Historic Kenwood is close enough to the bay and the Gulf that salt-laden air is a constant, not an occasional event. Combine that with intense, nearly year-round UV exposure and the wind-driven rain that comes with every tropical system, and you have a climate that punishes the wrong siding choice fast.
The Four Stressors That Matter Most
- Hurricane-force wind: Siding needs to stay fastened and intact under sustained wind loads and flying debris, not just look good on a calm day.
- UV exposure: Florida sun fades and degrades paint finishes faster than almost anywhere else in the country, especially on south- and west-facing walls.
- Wind-driven rain: Storms here don't just fall straight down — rain gets driven sideways and upward under laps and around trim, which is where most water intrusion problems start.
- Salt air: Airborne salt accelerates corrosion of fasteners and trim hardware and can degrade lesser materials over time.
Any siding installation in this neighborhood has to be judged against all four of these at once, not just one of them.
Why Historic Kenwood's Older Homes Need a More Careful Approach
Older neighborhoods like Historic Kenwood often have framing and sheathing that predates modern building codes. Stud spacing can be inconsistent, wall surfaces are rarely perfectly flat after decades of settling, and previous renovations sometimes left behind layers of old material, non-standard furring, or patched sheathing that isn't obvious until the old siding comes off.
A crew that treats every house like a new-construction box will miss these things. A crew that regularly works in older St. Petersburg neighborhoods knows to expect them — and plans the tear-off, sheathing inspection, and fastening pattern accordingly instead of discovering problems mid-job and improvising.
What We Check Before a Single New Board Goes Up
- Condition of the sheathing once old siding is removed — soft spots, old water staining, or rot get addressed, not covered over
- Flatness and plumb of existing walls, since older framing can be out of square by a noticeable margin
- Type and condition of the existing weather-resistive barrier (house wrap or felt), replaced where it's degraded
- Flashing at windows, doors, and roof-to-wall intersections — often the actual source of past leaks, independent of the siding itself
- Any signs of prior pest or moisture damage in the wall cavity that need remediation before re-siding
Why We Only Install James Hardie Fiber Cement
We standardized on James Hardie fiber cement siding for every home we side, including in Historic Kenwood, and we don't install vinyl, LP SmartSide, Cemplank, Allura, or primed wood products. That's a deliberate professional standard, not a marketing line.
In a climate with this much UV and salt exposure, the material matters more than almost anywhere else in the country:
- Non-combustible: Fiber cement doesn't burn, melt, or warp the way vinyl can in extreme heat or fire exposure.
- ColorPlus factory finish: A baked-on finish designed to resist UV fading far longer than field-applied paint, which matters enormously under Florida sun.
- Climate-engineered HZ5 formulation: James Hardie makes region-specific product formulations, and the HZ5 line is engineered for exactly the humidity and moisture cycling that Gulf Coast homes deal with.
- Dimensional stability: Fiber cement doesn't expand and contract with heat the way vinyl does, which keeps laps and seams tighter over time.
- Strong transferable warranty: A meaningful backing if you sell the home, which matters in a neighborhood where turnover and renovation are common.
Vinyl siding is inexpensive and easy to install, but it can soften, warp, or crack under sustained heat and wind-driven debris, and its finish is baked into the material itself rather than a factory-applied coating layer, so color options and long-term appearance are limited compared to Hardie's ColorPlus system. Wood-based and primed products require ongoing maintenance — repainting, sealing edges, watching for moisture — that most homeowners don't want to sign up for indefinitely, especially in a humid coastal climate that never really lets material dry out completely. We're not saying those products have no place; we're saying that after years of doing this work in this climate, fiber cement is what we're willing to put our name behind.
What a Correct Installation Involves
The material is only half the equation. A James Hardie installation is only as good as the details underneath it, and that's especially true on an older Historic Kenwood home where the substrate isn't perfectly uniform.
The Core Steps
- Full tear-off of existing siding and inspection/repair of sheathing
- Installation or replacement of a proper weather-resistive barrier
- Correct flashing at every penetration — windows, doors, hose bibs, vents, and roof lines
- Fastening per James Hardie's published installation instructions, including proper fastener spacing and embedment for wind zone requirements
- Correct clearances at grade, roof lines, and dissimilar materials to keep water moving away from the wall assembly
- Factory-finished ColorPlus panels and trim installed with the specified gaps and sealant approach to allow for material movement
Skipping or rushing any one of these steps is how a siding job that looks fine on installation day fails five or ten years later — usually in exactly the way local weather is designed to find: a gap that lets wind-driven rain in, or a fastening pattern that doesn't hold under hurricane-force gusts.
Comparison: Siding Material Trade-Offs in This Climate
| Factor | Vinyl | LP SmartSide / Wood-Based | James Hardie Fiber Cement |
|---|---|---|---|
| UV/fade resistance | Fades and can chalk over time | Depends on paint upkeep | ColorPlus factory finish resists fading |
| Wind performance | Can crack or blow off in high gusts | Adequate if properly fastened | Engineered and rated for high-wind zones |
| Moisture/humidity behavior | Doesn't rot, but can trap moisture behind it | Vulnerable to swelling if moisture reaches the core | Stable in high-humidity, coastal conditions |
| Combustibility | Can soften or melt under heat | Combustible | Non-combustible |
| Maintenance | Low, but limited repair options | Periodic repainting/sealing needed | Occasional caulk/touch-up, no full repaint cycle |
Our Process for a Historic Kenwood Job
Every project follows the same sequence, adjusted for what we find once the old siding comes off:
- On-site walkthrough and measurement, noting trim details, window/door conditions, and any visible problem areas
- Written estimate covering material, labor, and any anticipated sheathing or flashing repair allowances
- Tear-off and full inspection of the wall assembly before anything new goes up
- Repair of any compromised sheathing or framing discovered during tear-off, discussed with you before proceeding
- Installation of weather barrier, flashing, and James Hardie siding and trim to manufacturer specification
- Final walkthrough so you can see the completed work and ask questions before we consider the job done
We don't quote a job sight-unseen and we don't treat the estimate as the final word if tear-off reveals something that needs attention — you'll know before we proceed, not after.
Why Local Experience in This Neighborhood Matters
A contractor who has actually worked on Historic Kenwood homes before knows the general age and construction patterns common to the area, has a realistic sense of what tear-off is likely to reveal, and can price and schedule a job without guessing. That familiarity translates into fewer surprises, more accurate timelines, and installation decisions that account for what these specific homes tend to need — rather than applying a generic approach and hoping it fits.
It also means understanding Pinellas County permitting and inspection expectations for exterior work, which varies in its particulars from county to county across Florida. A crew that pulls permits and schedules inspections regularly in this jurisdiction moves through that process without unnecessary delay.
