Clearwater Siding Cedar Siding Looks Great in a Showroom. Clearwater Is Not a Showroom.
Cedar siding has real appeal. It's a natural product with genuine wood grain, warm color variation, and a traditional look that a lot of homeowners fall in love with at first sight. We understand why it shows up on wish lists. But we don't install it, and we think you deserve an honest explanation of why — not a sales pitch for what we do install instead, just the facts about how cedar actually holds up here in Pinellas County.
What Cedar Gets Right
To be fair to the product: cedar has natural oils that give it some inherent resistance to rot and insects compared to other softwoods, and it's genuinely a beautiful, renewable material. In a dry, moderate climate with low humidity and minimal direct sun exposure, cedar siding can perform reasonably well for a long time with regular upkeep. That's the key phrase — regular upkeep, in a climate that isn't working against it.
Where the Clearwater Climate Changes the Math
Cedar's biggest vulnerability is moisture, and Clearwater is a moisture-heavy environment almost all year. Between wind-driven rain, high year-round humidity, and long stretches of afternoon thunderstorms, cedar siding here spends far more time wet than the same board would in a drier climate. Wood swells when it absorbs water and shrinks when it dries out, and that repeated cycling stresses the boards, the joints, and the finish over time.
Add in a few more local realities:
- Intense, near-constant UV exposure breaks down wood fibers and finish coatings faster than in northern climates, leading to graying, checking, and surface erosion.
- Salt air, even well inland from the immediate coastline, accelerates the breakdown of finishes and can contribute to mold and mildew growth on organic wood surfaces.
- Hurricane-season wind and wind-driven rain force water into seams, laps, and fastener points, which is exactly where cedar is most prone to trapping moisture and rotting from the inside out.
- Pinellas County's humidity keeps wood surfaces damp longer after every rain event, which is the single biggest driver of mold, mildew, and fungal decay in wood siding.
None of this means cedar "fails." It means cedar requires a maintenance commitment that most homeowners underestimate when they're standing in front of a beautiful sample board.
The Real Maintenance Schedule
Properly maintained cedar siding in a climate like ours typically needs re-staining or re-sealing every 2 to 4 years, not the 7 to 10 years often advertised for cedar in milder regions. Skip a cycle, and you're not just losing curb appeal — you're exposing bare wood to sun and moisture, which is when checking, cupping, and rot start to set in. Repairs to individual boards are labor-intensive because matching grain and weathering on a patch job rarely looks seamless.
There's also the practical question of who does that maintenance. Staining and sealing wood siding correctly requires proper surface prep, the right products, and correct timing around weather — it's not a weekend project most homeowners want to take on every couple of years, and hiring it out repeatedly adds up over the life of the siding.
A Straightforward Comparison
| Factor | Cedar Siding | James Hardie Fiber Cement |
|---|---|---|
| Moisture behavior | Absorbs water, swells/shrinks | Engineered to resist moisture damage |
| Refinishing cycle (this climate) | Every 2-4 years | ColorPlus finish holds color for years without repainting |
| UV/salt air resistance | Fades, grays, breaks down | Formulated for sun and coastal exposure |
| Fire behavior | Combustible | Non-combustible fiber cement |
| Long-term cost | Lower upfront, higher lifetime upkeep | Higher upfront, lower lifetime upkeep |
Why We Standardized on James Hardie Instead
We made a decision as a company to install only James Hardie fiber cement siding, and cedar is one of the clearest examples of why. Hardie's HZ5 product line is specifically engineered for hot, humid, storm-prone climates like ours — it's built to resist moisture intrusion, hold up under intense UV, and shrug off the salt air that comes with living near the Gulf. The factory-applied ColorPlus finish is baked on under controlled conditions, so it resists fading and holds up far longer than a field-applied stain, without the 2-4 year refinishing cycle cedar demands.
Fiber cement is also non-combustible, which matters to a lot of homeowners and insurers alike, and it doesn't invite the wood-boring insects or fungal decay that organic wood siding can attract in a humid environment. Backed by a strong transferable warranty and installed to manufacturer spec, it's a product built for exactly the conditions Clearwater throws at a house year-round — hurricane season, summer humidity, and relentless sun alike.
We're not going to tell you cedar is a bad product — in the right climate, it isn't. We just don't think this is the right climate for it, and we'd rather be straight with you about that upfront than sell you something we know will become a maintenance headache.
