Alpine Exteriors is a siding company serving Sarasota and the surrounding barrier island and inland communities. We install exactly one siding system: James Hardie fiber cement. We don't carry vinyl, we don't carry LP SmartSide, and we don't install engineered wood siding. That's not a marketing angle — it's a decision about what holds up in a Gulf Coast climate with real humidity, salt air near the water, and a storm season that runs June through November. Specializing in one product means our crews aren't relearning installation details on every job. They know Hardie's fastening patterns, clearances, and joint treatments cold, because it's the only system they touch.
This page walks through how we actually work as a company — the estimate process, what installation looks like on your property, how our warranty is structured, and which parts of the Sarasota area we cover. If you're comparing siding contractors, this is the operational detail that's usually missing from a sales pitch.
Sarasota County sits on the water. Whether you're in a coastal neighborhood off Siesta Key, Casey Key, Lido Key, or set back inland around Fruitville, Bee Ridge, or out toward Laurel and Lakewood Ranch, your siding deals with the same underlying conditions: sustained humidity most of the year, intense UV exposure, wind-driven rain during tropical systems, and for homes closer to the coast, salt in the air that accelerates corrosion on the wrong materials.
Fiber cement is cement, sand, and cellulose fiber — it doesn't rot, it doesn't feed termites, and it doesn't soften when it stays wet for days after a named storm sits offshore. Vinyl can warp and crack under sustained heat and UV, and its seams are a weak point in wind-driven rain. Engineered wood products use wood fiber with a resin binder, which means moisture intrusion at a cut edge or fastener point is a real long-term risk in a climate this humid. We don't frame these as bad products in the abstract — we frame it as our standard: for Sarasota's specific combination of heat, moisture, and storm exposure, fiber cement is the trade-off we're willing to install and warranty. James Hardie is the manufacturer we use because their ColorPlus finish, HZ5 climate-specific formulation, and product consistency give us a system we can install the same way, correctly, every time.
Every project starts with a walk of the exterior, not a phone quote. A siding estimate that's accurate has to account for your home's actual wall assembly, existing siding condition, window and door trim details, and any moisture damage that needs to be addressed before new siding goes on — none of which you can judge from a photo.
You get a written proposal that specifies the Hardie product line (lap, shingle, or panel), the exposure reveal, the color or finish, and a line-item cost breakdown — not a lump sum. That's what lets you compare our quote against another siding company's apples to apples.
Fiber cement is unforgiving of shortcuts in a way vinyl isn't — a missed clearance or wrong fastener pattern shows up as cracking or moisture problems years later, not on day one. So the process is methodical.
We remove the old siding, inspect and repair or replace damaged sheathing, and install a weather-resistant barrier per Hardie's published requirements before a single board goes up. In Sarasota's climate, this step matters more than almost anywhere else in the country — trapped moisture behind siding doesn't dry out the way it might in a drier region.
Every board is fastened per Hardie's engineering data for our wind zone, with correct nail spacing, clearances at grade, roofline, and any penetrations, and properly treated butt joints. We don't caulk over gaps that should have been cut tight, and we don't face-nail where blind-nailing is specified.
Trim, corners, and caulking get finished to a clean, factory-look edge. If you selected primed siding rather than ColorPlus prefinished, we coordinate the paint schedule so the exposed cut edges and field are properly sealed before Florida's humidity has a chance to work on raw material.
We walk the完 job with you, point out what was done, and address any punch-list items before we consider it complete.
| Hardie Product | Look | Common Use in Sarasota |
|---|---|---|
| HardiePlank lap siding | Traditional horizontal board look | Most common choice across coastal and inland neighborhoods alike |
| HardieShingle | Staggered or straight-edge shingle profile | Coastal cottage and Old Florida style homes |
| HardiePanel | Vertical board-and-batten | Accent walls, gables, and modern coastal builds |
| ColorPlus finish | Factory-baked color, no field painting | Preferred near the water where repainting is a recurring chore |
Siding warranties have two layers, and it's worth understanding both before you sign with any siding company.
James Hardie backs their siding with a non-prorated limited warranty on the product itself, and ColorPlus finishes carry their own separate finish warranty covering fade and peeling. These are Hardie's terms, tied to the product, and they follow the home even if you sell it, subject to Hardie's registration requirements.
Separately, we warranty our installation labor. If a failure traces back to how the siding was installed — fastening, flashing, clearances — rather than a manufacturer defect, that's on us to correct. We'll go over the specific term and what's covered in writing as part of your proposal, because "warranty included" without the actual document isn't a warranty you can rely on.
We work throughout Sarasota County, including the barrier islands (Siesta Key, Lido Key, Casey Key), downtown Sarasota, and the inland growth corridors around Fruitville Road, Bee Ridge, Palmer Ranch, and out toward Lakewood Ranch. Coastal and inland jobs aren't identical — homes closer to the Gulf see more salt exposure and often need corrosion-resistant fastener specs and more attention to trim material at grade, while inland homes further from direct salt air still deal with the same heat and humidity load and typical Florida storm season rainfall. We adjust the installation spec to where your home actually sits, not a one-size approach.
If your project falls during June through November, we build the schedule around forecasted systems rather than ignoring them. Fiber cement installation shouldn't happen in the middle of active rain, and open wall sections need to be protected if a system is approaching. We'll communicate proactively if a storm forecast affects your install date rather than leaving your home exposed to make a deadline.
If your Sarasota home needs new siding, a repair after storm damage, or you're planning ahead of a sale, we're happy to walk the exterior with you and put together a straightforward, itemized estimate. There's no pressure and no obligation — just an honest look at what your home needs and what it would cost to do it right with James Hardie fiber cement.
We standardize on one product so our crews install it correctly every time rather than switching techniques between materials. For Sarasota's humidity, UV exposure, and storm season, fiber cement's moisture and impact resistance is the trade-off we're willing to stand behind with a workmanship warranty.
In Florida, check the contractor's license number against the Florida Department of Business and Professional Regulation's online lookup, which shows license status, type, and any disciplinary history. Alpine Exteriors is licensed under RB29003900 — ask any contractor for their license number before signing anything.
HardiePlank refers to the lap siding profile itself, while ColorPlus is Hardie's factory-applied color finish baked onto the board before installation. ColorPlus is popular near the coast because it resists fading and chipping better than field-applied paint and skips a repainting cycle.
Fiber cement siding installed to Hardie's wind-zone fastening specifications holds up to wind-driven rain and debris impact better than most alternative sidings, and it won't absorb and hold water the way some materials can after a storm. It's one piece of overall storm readiness, not a substitute for proper roof and opening protection.
Timelines vary with home size, existing siding condition, and any sheathing repairs needed underneath, but most single-family homes run from a few days to a couple of weeks of active work. We'll give you a project-specific schedule during the estimate, including how storm season forecasts might affect timing.
