"Siding contractor" is one of those job titles anyone can put on a truck door. In Pinellas County, where storm season brings out a wave of door-knockers every summer, it's worth knowing what separates a real contracting operation from a crew working out of a pickup truck. Alpine Exteriors holds Florida license RB29003900, and every siding job we run in Largo is permitted, inspected, and installed by people who do this work full-time — not subcontracted out to whoever's available that week.
This page isn't a general "here's what siding is" overview. It's specifically about how we operate as a contractor: our process, our warranty structure, where we work around Largo, and what a homeowner should expect once a contract is signed. If you're comparing bids right now, this is the information that actually helps you tell one contractor from another.
Alpine Exteriors does not install vinyl siding, LP SmartSide, or other engineered wood products. This isn't a marketing angle — it's a decision we made about which product we're willing to warranty our labor against in a Gulf Coast climate.
Vinyl softens and warps in direct summer sun and can crack in a hard freeze snap (rare here, but it happens). It also telegraphs every imperfection in the wall behind it, which makes it a poor match for the older, slightly out-of-square framing common in Largo's mid-century housing stock. Engineered wood products use wood fiber with a resin binder, which means their long-term performance depends heavily on caulking, flashing, and maintenance staying perfect for decades — a hard ask in a humid subtropical climate with heavy afternoon rain nine months a year.
James Hardie fiber cement is cement, sand, and cellulose fiber. It doesn't feed mold, it holds paint far longer than wood-based products, and it's rated for wind-driven rain exposure — a real consideration for a county that sees tropical systems most years. We install the HardiePlank lap siding, HardieShingle, and HardiePanel lines depending on the home's architecture, all factory-primed or in Hardie's ColorPlus baked-on finish.
Fiber cement costs more upfront than vinyl and is heavier to install, which means labor runs longer and requires a crew that's trained specifically on it — improper fastening or clearance is the #1 cause of premature failure in fiber cement, and it's almost always an installation error, not a product defect. That's exactly why we don't treat it as a side skill; it's the only siding product our crews install.
Every siding project follows the same sequence, whether it's a single elevation repair or a full re-side:
Largo sits inland of the barrier islands — Indian Rocks Beach and Belleair Beach are a short drive west — so homes here get less direct salt spray than oceanfront properties, but they're not spared the humidity, heat, and rain that define Pinellas County. Afternoon thunderstorms roll in almost daily from June through September, and the county sits squarely in the Tampa Bay hurricane exposure zone, with active storm season running June through November.
That combination — sustained humidity, intense UV, and periodic wind-driven rain — is hard on siding that isn't built for it. Fiber cement doesn't absorb moisture the way wood-based products do, and it holds up to UV exposure without the chalking and fading that shortens the usable life of vinyl in Florida sun. For homes near Eagle Lake Park, Largo Central Park, or the older canal-adjacent lots on the city's west side, drainage and ground clearance around the siding base matter just as much as the product choice — something we account for at installation, not as an afterthought.
We take on siding projects across Largo's residential neighborhoods, from the established mid-century subdivisions near Highland Recreation Complex to newer construction further east toward Ulmerton Road. Our service area also covers the surrounding Pinellas communities — Clearwater, Seminole, Pinellas Park, and Belleair — so a Largo project scheduled alongside a neighboring job often means tighter scheduling and less downtime between phases.
A lot of Largo's housing stock dates to the 1960s–80s, which means original aluminum or early-generation vinyl siding is common and often past its practical service life. If your siding is original to a home from that era, it's worth an inspection regardless of how it looks from the street — moisture problems at the sheathing level don't always show up on the surface first.
| Coverage | What it includes | Length |
|---|---|---|
| Manufacturer product warranty | James Hardie's non-prorated coverage on the siding material itself against manufacturing defects | 30 years (siding), per Hardie's published terms |
| Manufacturer finish warranty | ColorPlus factory finish coverage against peeling, cracking, and fading | Per Hardie's published ColorPlus terms |
| Alpine Exteriors labor warranty | Our installation workmanship — flashing, fastening, sealing | Provided in your written contract |
The distinction that matters: a manufacturer warranty covers the product; it does not cover a bad install. That's why we register eligible jobs with Hardie where applicable and back our own labor separately in writing — if something fails because of how it was put on the wall, that's on us, not a warranty claim you have to fight for.
| Factor | Why it matters |
|---|---|
| Square footage & home shape | More corners, dormers, and cutouts mean more labor and trim work per square foot |
| Substrate condition | Rotted sheathing found during tear-off adds repair cost before new siding goes up |
| Siding profile | Lap, shingle, and panel styles have different material and labor costs |
| Finish | Factory-primed (field-painted) vs. ColorPlus baked-on finish |
| Access & site conditions | Fencing, landscaping, second-story reach, and tight lot lines affect labor time |
Whether you go with us or someone else, these are the questions that separate a real contractor from a storm-chasing crew: Is your license active and verifiable with the state? Will you pull the permit yourself, or expect me to? Is your warranty in writing, and does it cover labor separately from the product? Who's actually on the crew doing the install — employees or day-labor subs? A contractor confident in their work will answer all four without hesitation.
If your Largo home needs a siding assessment — whether it's storm damage, an aging original install, or you're just tired of repainting — we'll come look at it and give you a straight answer, no pressure. Use the form below to request a free estimate.
A licensed contractor like Alpine Exteriors (FL RB29003900) carries the insurance, permitting authority, and accountability required by Florida law for exterior construction work. An unlicensed installer may skip permits entirely, which can create problems later when you sell the home or file an insurance claim tied to that work.
Florida's Department of Business and Professional Regulation (DBPR) has a free online license lookup where you can search a contractor's license number and confirm it's active and in good standing. Any legitimate contractor will give you their license number without hesitation — treat reluctance as a red flag.
We standardized on James Hardie because it's the most established fiber cement manufacturer in the Florida market, with a long track record, wide color and profile selection, and warranty support we can stand behind. Sticking to one product line also means our crews are deeply trained on its specific installation requirements rather than spread thin across brands.
You can choose factory-primed HardiePlank, which needs field painting after install, or Hardie's ColorPlus finish, which is a baked-on factory color that arrives ready to install with a longer finish warranty. Most Largo homeowners choose ColorPlus specifically to avoid a repaint cycle in Florida's intense UV.
Yes — siding replacement in Largo and unincorporated Pinellas County requires a building permit and inspection, since it involves the home's weather barrier and structural sheathing. We handle the permit application and schedule the required inspections as part of every project.
