Hardie Siding Installation & Replacement in Sebastian, FL
TradeWinds Construction is a Hardie siding contractor based in Sebastian, serving homeowners across Florida's Treasure Coast. Fiber cement siding installed the way the manufacturer intends, with the flashing and water management done right behind it.
Siding is the one part of a Florida house that never gets a day off. Sun chalks cheap material. Wind-driven rain finds every loose lap. Salt air eats bare fasteners, and termites treat soft wood trim like a delivery order.
Hardie siding is fiber cement. Cement, sand, and cellulose fiber pressed into board. It does not rot, it gives termites nothing to eat, it will not melt off a wall, and it holds paint the way wood wishes it could. On this coast, that combination is hard to beat, which is why Hardie Board siding has become the largest single service we run.
We install it on new work and we tear off and replace failing siding on houses built anywhere from the 1950s to last decade. Either way, the board is only half the job. House wrap, flashing, and clean transitions at every window and door are what actually keep water out of the wall.

Hardie siding installation
On an installation we set the water management first, then hang board. Every course gets the right fastener, the right overlap, and the clearances Hardie specifies at the roof, the deck, and the grade. Cut ends get sealed. Butt joints land where they belong.

Hardie siding replacement
Replacement starts with taking the old siding off, not covering it. Once the wall is open we can see what is actually going on, and on older houses there is usually something. Soft sheathing at the bottom courses. Rot under a window that was never flashed.
When we find it, we show you, price the repair in plain language, and fix the sheathing before new board goes on. Covering rot with new material is not a job we will take.
Replacing one elevation at a time is a fair way to stage the cost, and we are happy to price it that way.
What fiber cement siding actually gets you
The reasons homeowners on the Treasure Coast keep landing on Hardie Board siding, in the order they usually come up.
Durability
Fiber cement does not rot, swell, or split. Termites and woodpeckers get nothing out of it. Hardie backs the board with a 30-year limited transferable warranty, which is a longer horizon than most people plan to own the house.
Fire resistance
Hardie board is noncombustible. It will not ignite and it will not feed a fire, which matters most where houses sit close together or where a grill, a lanai, or a neighbor's roof is near the wall.
Weather resistance
Engineered for coastal climates and rated for high wind. It shrugs off wind-driven rain, holds up to sun and salt air, and does not soften in Florida heat the way vinyl can.
Low maintenance
No annual scraping and repainting. A rinse with a garden hose and a look at the caulk joints once a year is most of the upkeep. With a ColorPlus finish, repainting is measured in decades instead of a few seasons.
ColorPlus technology
Field paint on new siding is a compromise. It goes on in whatever humidity the day gives you, over a surface that has been sitting in a driveway, and it starts its clock the moment the crew leaves.
ColorPlus is Hardie's factory finish. Color is applied in multiple baked-on coats inside a controlled plant, on board that has never seen weather. It resists fading, chipping, and cracking far better than anything rolled on at your house, and it carries its own finish warranty on top of the 30-year board warranty.
Boards show up in your color. Trim, corners, and touch-up paint come from the same run, so the whole house matches. We will bring real samples and hold them against your roof and your neighbors' houses before you commit.

Hardie siding questions, answered plainly
Is Hardie siding worth it in Florida?
For most homes on this coast, yes. Fiber cement does not swell, rot, or feed termites the way wood does, and it will not soften or warp in Florida heat the way vinyl can. It is heavier and costs more to install than vinyl, and it is the material we recommend most often for houses that see sun, salt air, and wind-driven rain.
How long does Hardie siding last?
Properly installed Hardie Board siding is built to serve for decades, and Hardie backs the fiber cement board with a 30-year limited transferable warranty. The finish matters as much as the board. A ColorPlus finish carries its own separate finish warranty, which is why we recommend it on most jobs.
Does Hardie siding really help with fire?
Fiber cement is noncombustible. Hardie boards are made from cement, sand, and cellulose fiber, so the siding itself will not ignite or feed a fire the way wood or vinyl will. That is one of the reasons this material gets specified on homes where the siding sits close to a neighboring structure.
What is ColorPlus technology, and do I still have to paint?
ColorPlus is Hardie's factory-applied finish. The color goes on in a controlled plant in multiple baked-on coats instead of being rolled on at your house, so it resists fading and chipping far better than field paint. Boards arrive already in your color. You do not paint after installation, and repainting is measured in many years rather than a few.
Can you replace just one side of the house?
Yes. Weather rarely wears all four walls evenly, and doing the worst elevation now is a fair way to stage the cost. We will match profile and color as closely as available product allows and tell you honestly when a partial replacement will show.
Do you install Hardie siding over existing siding?
No. We take the old siding off. Going over the top hides rot, buries flashing problems, and makes the wall assembly thicker than the trim details were built for. We strip to the sheathing, repair what we find, install house wrap and flashing, and then hang new board.
How much does Hardie siding cost?
It depends on the size of the house, the number of stories, how much trim and detail work is involved, and what we find once the old siding comes off. Hardie costs more up front than vinyl and less over its life. We measure your house, put the scope in writing, and give you one number with no vague allowances.
