Fiber cement siding is one of the most durable exterior claddings you can put on a house. It resists fire, termites and rot, holds paint well and carries a long manufacturer warranty. What you plan for is weight, a installer who follows the details, and hail-prone weather. In Central Texas, where heat, hail and sudden storms are routine, James Hardie fiber cement installed correctly is the siding we recommend most often. This guide gives you the pros, the planning points, a plain comparison with LP SmartSide, and the next steps.

What fiber cement siding is
Fiber cement is a board made from sand, water, cellulose fibers and Portland cement, plus proprietary additives. Portland cement is the same binder used in concrete. James Hardie's HardiePlank is the best-known version. Because the board is mostly mineral, it behaves very differently from wood, vinyl or engineered wood.
A typical HardiePlank lap board is 5/16 inch thick and 12 feet long, and weighs 2.31 pounds per square foot. It comes in widths from 5-1/4 to 12 inches, so you can match the look of the original siding on your house or change it.
The pros of fiber cement siding
Fire resistance
This is the clearest advantage. Hardie fiber cement is noncombustible. The HardiePlank submittal sheet reports a flame spread index of 0 and a smoke developed index of 5 in ASTM E84 testing. For homes in dry, hot parts of Central Texas, where grass fires and neighbor fires are a real concern, that matters.
Pest and rot resistance
Termites are a fact of life in Texas. According to the Pacific Northwest National Laboratory's building guide, metal, stone, fiber cement, vinyl and many wood composites perform well in termite regions because they do not attract termites. Fiber cement also will not be attacked by wood-boring insects such as ants or termites. Unlike wood, it does not rot or warp when it gets wet.
Warranty and lifespan
Manufacturer coverage tells you how much the maker stands behind the board. Hardie products come with a 30-year, non-prorated warranty. Non-prorated means the coverage does not shrink year by year. Across the category, fiber cement warranties can run as long as 50 years. A warranty covers the product, so a clean installation is what lets the board reach its potential. More on that below.
Looks and color choice
Hardie planks come in a range of styles, textures and colors, including woodgrain looks. The factory ColorPlus finish has a 15-year limited warranty covering paint and labor against peeling, cracking and chipping. If you are updating siding to raise curb appeal before a sale or a refinance, color matters as much as material. Our guide to siding colors for 2026 covers what is popular and how to choose.
Holds paint well
Fiber cement is a stable base for paint. Installed over a vented rainscreen, an air gap behind the siding, it helps the paint last longer. Yes, Hardie board can be painted, and factory-finished boards save you the on-site painting step.
What to plan for with fiber cement
Every siding has trade-offs. No material wins every category, and life-cycle research on exterior wall finishes finds that cost, service life and environmental impact all have to be weighed together. These are the points to plan around so fiber cement performs the way it is designed to.
Hail and impact
Fiber cement is fire and pest resistant, and it is also more rigid than some other materials. PNNL notes that this rigidity makes it more prone to cracking when struck by high-impact debris. In Central Texas, that means large hail can crack a board. The fix is usually replacing individual boards, which is straightforward when the crew can source matching planks. If hail has hit your home, document the siding as well as the roof. Our siding insurance claim steps walk through how to avoid denials.
Weight and installation
Fiber cement is heavier than vinyl, so it takes more hands and the right tools. James Hardie says installation typically takes seven to 14 days for an average-sized home and uses fasteners approved under ICC-ES ESR-2290. It recommends blind nailing, where the nail is hidden, for a seamless look, though some high-wind areas require face nailing by code. These are details a skilled crew handles daily. Labor is a large part of the price, so quotes can differ more on crew skill than on board cost.
Moisture detailing behind the board
Fiber cement resists water, but the wall behind it still has to shed water. Good jobs use a weather barrier, flashing and a vented gap. Our article on house wrap under siding and why flashing comes first explains what to expect from a crew. One 2014 building-science article argues that moisture and freeze-thaw cycling drive fiber cement breakdown in cold climates. That is a reason to insist on correct assembly, and Central Texas has few freeze-thaw cycles compared with northern states.
Cutting dust
Cutting fiber cement creates silica dust, which can cause silicosis. Crews should use dust control and respiratory protection. This is a major reason to have a professional crew do the cutting rather than doing it in your driveway. If you are a homeowner, keep children and pets away from the work area during installation.
Upfront cost
Fiber cement usually costs more up front than vinyl. NAHB advises comparing the total in-place system price: materials, labor, and paint or stain, rather than the price of the board. Painted wood needs repainting and repair, so its total cost over time looks different. We do not quote a per-square-foot number here because it changes with house size, story count, trim and the market. A written estimate for your house is the only number that counts.
Fiber cement durability, in plain terms
Here is what durability means for a Texas house:
| Threat | How fiber cement responds |
|---|---|
| Fire | Noncombustible; flame spread index of 0 in testing |
| Termites and insects | Not attacked by wood-boring insects |
| Rot and warping | Does not rot or warp like wood |
| Moisture | Water resistant; needs a proper wall assembly and sealed edges |
| Hail and impact | Rigid, so large hail can crack boards; individual boards can be replaced |
| Sun and heat | Needs sound paint and caulk; inspect them regularly |
The sources above support the first four rows. The last two come down to maintenance and installation quality.
Fiber cement siding maintenance
The routine is light. Walk the house once or twice a year and look for cracked or loose boards, gaps in caulk at trim and corners, peeling paint, and any spot where water stands against the wall. Wash the siding gently to remove dust and mildew. Keep sprinklers from spraying the walls, and keep plants trimmed back so air can reach the siding. Repaint when the finish fades or wears, and touch up any chips before water reaches the board.
Our Central Texas guide to Hardie board maintenance, DIY steps and when to hire covers the washing and caulking in detail. Anything involving ladders, cutting or replacing boards is better left to a crew.
James Hardie vs LP SmartSide
These two come up together because they look alike on a house. They are built differently.
| James Hardie fiber cement | LP SmartSide | |
|---|---|---|
| Material | Sand, cement, cellulose fibers | Engineered wood strands with a protective treatment |
| Fire | Noncombustible | Wood-based product |
| Pests | Does not attract pests | Treated to resist pests |
| Warranty | 30-year, non-prorated | Set by the maker; read the terms |
| Weight | Heavier board, 12 ft lengths | Lighter, longer boards |
| Our pick | Yes |
LP SmartSide is lighter and comes in longer boards, which can speed up a job. For a Texas home we still choose fiber cement. A mineral board does not burn, and it is the product we build our siding work around. If you are weighing the two for cost, keep in mind the board is only part of the price. Labor, trim, flashing and paint make up the rest, so ask each contractor to price the same scope with the same trim and finish.
On "Hardie board vs LP" cost, the useful comparison is two written estimates for your house, not retail price per board.
Is fiber cement worth it for your home?
Fiber cement is a strong fit if you:
- live in a termite or wildfire-exposed area and want a noncombustible wall,
- plan to stay in the house long enough to use a 30-year warranty,
- want a paintable, woodgrain-look siding without wood's upkeep,
- are replacing storm-damaged siding and want the repair to last.
If you have hail damage, check your homeowner's policy before you replace anything. Our insurance claims service helps homeowners through the claim.

How to get a fiber cement siding job done right
- Inspect the walls first. Look for soft spots, stained sheathing and failed caulk. Hidden water damage changes the scope.
- Settle the scope in writing. Board type, trim, flashing, house wrap, paint or ColorPlus finish, and how old siding is removed and disposed of.
- Collect multiple estimates. Compare like for like. A much lower number often means something is left out.
- Check the moisture details. Ask what goes behind the siding and how windows and corners are flashed.
- Confirm the warranty paperwork. Know what the manufacturer covers and what the contractor covers.
- Handle the insurance side early. If the damage came from a storm, file before repairs begin and keep photos.
