Anyone with a truck and a nail gun can call themselves a siding contractor. Dunedin homeowners deserve better than that, especially given what this stretch of the Gulf coast does to a home's exterior. Between the humidity rolling off St. Joseph Sound, the salt air near the causeway and Honeymoon Island approach, and the afternoon storms that build almost daily from June through the end of hurricane season, siding here has to perform, not just look good on installation day. This page is about us as a contractor: how we're licensed, how we run a project, what our warranty actually covers, and what you can expect from the first phone call to the final walkthrough.
We are not going to repeat a generic rundown of siding materials here. If you want the full product breakdown, that lives on our other pages. This page answers the question homeowners in Dunedin ask most often once they've decided they need work done: who am I actually hiring, and how do they operate?
Alpine Exteriors operates under Florida license RB29003900. That license means our work is subject to state building code standards, our insurance is current, and there's a paper trail if anything ever needs to be addressed. In a coastal market like Pinellas County, where storm damage and insurance claims are part of normal homeownership, working with a licensed contractor isn't a formality — it's what makes your paperwork hold up if you ever need to file a claim or sell the house.
If a contractor won't answer these plainly, that's your answer. We go over every item on this list with homeowners before a single board goes up.
We start at your house, not with a phone quote. A siding job in Dunedin isn't just about the visible boards — we're checking the sheathing underneath, looking for signs of moisture intrusion around windows and eaves, and noting anything storm-related that insurance might need to see. Older homes in the downtown Dunedin core and along Edgewater Drive often have different wall assemblies than newer construction near Curlew Creek, so the assessment isn't cookie-cutter.
We walk you through James Hardie profile and color options that fit your home's style and your neighborhood, whether that's a Florida cottage close to downtown or a newer build further inland. You get a detailed, itemized proposal — not a one-page estimate — so you know exactly what's being installed and where.
We pull the required permits before any work starts. We also build the schedule around Florida's wet season realistically — afternoon thunderstorms are a daily fact of life here from June into fall, and a contractor who promises a rain-proof timeline in August isn't being straight with you. We plan around it instead of pretending it won't happen.
Our crews follow James Hardie's published installation specifications, including proper fastener spacing, clearance from grade, flashing details around windows and doors, and correct joint treatment. This is the step where most siding failures actually originate — not from the material, but from shortcuts during install. We don't take them.
Before we consider the job finished, we walk the exterior with you, point out the details, and answer questions. Site cleanup includes nails, offcuts, and packaging — we don't leave debris for you to find weeks later.
We made a deliberate decision as a company: we install James Hardie fiber cement siding exclusively. We don't offer vinyl, LP SmartSide, or other engineered wood products, and that's a standard we hold ourselves to, not a knock on every homeowner who has one of those products already on their house. Here's the honest reasoning behind it, particularly for a Gulf coast climate like Dunedin's.
| Factor | James Hardie Fiber Cement | Vinyl | Engineered Wood |
|---|---|---|---|
| Moisture behavior in humid coastal air | Cement-based composition doesn't absorb moisture or swell | Can warp or buckle in extreme heat and humidity swings | Wood-fiber core is vulnerable to moisture if the finish is compromised |
| Wind resistance | Engineered and tested for high-wind regions like ours | Lighter panels can be more prone to wind damage in storms | Variable depending on manufacturer and installation quality |
| Installation sensitivity | Requires trained crews following exact fastening and clearance specs | Simpler install, but still needs correct expansion allowances | Sensitive to cut-edge sealing; errors shorten lifespan significantly |
| Long-term maintenance | Repaint cycle typically longer; material itself doesn't rot | Low maintenance but can fade and become brittle over time | Requires diligent upkeep to protect the wood-fiber core |
| Warranty structure | Manufacturer's non-prorated limited warranty on the product | Varies widely by manufacturer and product tier | Often shorter or more conditional than fiber cement warranties |
We're not saying vinyl or engineered wood can't work anywhere — plenty of homes around the country wear them fine. We're saying that for the combination of salt air, humidity, and wind exposure that comes with living near the Gulf, fiber cement is the material we're willing to put our name and warranty behind. Standardizing on one manufacturer also means our crews are deeply practiced with one system instead of stretched thin across several, and that shows up in the quality of the finished install.
There are two separate warranties on every project, and homeowners deserve to understand both.
James Hardie backs its siding products with a non-prorated limited warranty covering the material itself against defects. Because fiber cement is engineered for climates like Florida's, this warranty reflects real confidence in how the product holds up to heat, humidity, and coastal exposure over decades, not just a few seasons.
This is the part that depends entirely on who installed your siding. Our workmanship warranty covers our labor and installation — the flashing, fastening, and joint work that determines whether the product performs the way it's designed to. If an installation defect shows up, it's on us to make it right, not on you to chase down a subcontractor who's no longer in business.
Before hiring anyone, ask for the workmanship warranty in writing, with a specific term length. A verbal "we stand behind our work" isn't a warranty.
We work throughout Dunedin — from the historic downtown core and Edgewater Drive corridor near the Gulf, out through the neighborhoods along Curlew Road and Michigan Boulevard, up toward the Palm Harbor line, and the residential streets around the Pinellas Trail and Hammock Park. Coastal-facing homes closer to the water tend to see more direct salt exposure and wind-driven rain, while inland properties deal more with prolonged humidity and afternoon storm runoff — both are things we plan for differently during the assessment. We also serve the surrounding Pinellas County communities near Dunedin, so if you're just outside the city line, reach out and we'll confirm coverage.
A little preparation on your end keeps the project moving smoothly:
If you're weighing siding contractors in Dunedin and want straight answers about licensing, process, and what our warranty actually covers, we're glad to walk through it with you. Reach out for a free, no-pressure estimate — someone will come look at your specific home rather than guess over the phone.
Verify their state contractor license number against Florida's public license lookup, confirm current general liability and workers' compensation insurance, and ask for a written proposal with specific product names and quantities. A contractor who's vague about any of these is a red flag, especially in a market where storm-related insurance claims are common.
Ask for addresses of recent local projects, not just names and phone numbers, so you can see finished work in person if you want to. A contractor with a real Pinellas County track record should have no hesitation pointing you to jobs in the area.
We standardized on James Hardie fiber cement because it holds up well to the humidity, salt air, and wind exposure common along the Gulf coast, and it lets our crews specialize deeply in one installation system rather than spreading training across several products. It's a standard we set for our own work, not a claim that other materials can't function anywhere.
HardiePlank is horizontal lap siding, the traditional clapboard look most common on Dunedin homes, while HardiePanel is a large vertical sheet often used for accent walls, gables, or a more modern board-and-batten style. Both are fiber cement, so the choice usually comes down to the architectural look you want rather than performance differences.
Florida's wet season runs roughly June through November, with near-daily afternoon storms and the possibility of tropical systems, so we build realistic weather buffers into scheduling rather than promising a fixed timeline. Many homeowners choose to schedule siding projects in the drier late fall through spring months to reduce weather-related delays, though we work year-round.
