HomeFiber Cement Siding
Fiber cement siding, handled the way its weight and dust actually demand.
Fiber cement is a heavier, harder, and more particular material to work with than vinyl, and it rewards a crew that treats it that way. Correct fastening into framing, cutting methods that keep silica dust down, and knowing which cut edges need field paint before the wall closes back up are what decide whether a fiber cement job looks right in year one and still looks right in year twenty.
Why fiber cement handles differently than vinyl
Fiber cement is made from cement, sand and cellulose fiber pressed and cured into a hard, dense board, and it carries weight to match. A typical fiber cement lap board runs around 2.3 pounds per square foot of coverage, which works out to roughly 230 pounds for a 100-square-foot square, noticeably more than a comparable run of vinyl siding. That is not a problem for a house's structure. Homes are built to carry far more than a layer of cladding. It is a problem for the crew, because it changes how the material has to be staged, carried and fastened.
Boards get hand-carried in pairs rather than solo on anything but the shortest pieces, staging on scaffolding or ladders is planned around not overloading a single point, and fasteners go into the framing or nailable sheathing rather than relying on the panel to hold its own weight between studs the way vinyl can. Corrosion-resistant nails, driven flush but not overdriven (a fastener sunk too deep crushes the board's edge and creates a weak point), are what actually keep a heavy board from working loose over the years.
Cutting it safely, not just cutting it fast
Fiber cement contains crystalline silica, and cutting it dry with a standard blade throws fine dust into the air that is genuinely bad to breathe repeatedly over a career. OSHA's respirable crystalline silica standard for construction, 29 CFR 1926.1153, requires a written exposure control plan for any crew doing this work regularly, and it lays out specific control methods for saws used on fiber cement board.
In practice that means we cut with a saw fitted with a blade made for the material and equipped with vacuum dust collection whenever a power saw is the right tool, or we use manual or pneumatic shears and the score-and-snap method, which throw far less dust to begin with. Dry sweeping cut dust afterward is exactly the wrong move. Wet suppression or a vacuum is what actually clears it instead of just putting it back in the air. None of this changes how the finished wall looks. It changes what the crew installing it breathes for the next twenty years, which is worth doing right regardless of who is watching.
Factory finish vs. a field-painted board
Fiber cement comes two ways: pre-finished with a factory-applied coating cured under controlled conditions, or primed only, meant to be painted on site after installation. The factory-applied option generally holds its color and film integrity longer than a field-applied coat, since it is cured in a way a paintbrush and Indiana weather cannot replicate, and many factory finishes carry their own manufacturer coating warranty as a matter of industry practice.
Whichever route a house takes, cut edges always need attention. A saw or shear exposes raw, unfinished material at every end cut, and that edge needs field-applied touch-up paint or sealant before the wall is considered finished, factory finish or not. It is a small step that gets skipped on rushed jobs and shows up a few years later as a discolored line at every board end. Once a factory-finished wall does eventually need a full repaint down the road, see exterior painting for how we handle prep on a fiber cement surface.
Fiber cement formats we install
| Format | Typical spec | Best fit | Worth knowing |
|---|---|---|---|
| Lap siding | 5/16 in planks, smooth or cedar texture | Traditional lap look on most elevations | The format we install most. Blind-nailed at the top edge where possible to keep fastener heads out of view. |
| Panel siding | 4x8 or 4x9 ft sheets, smooth or textured | Board-and-batten looks, porch ceilings, modern elevations | Fewer seams than lap boards but heavier per piece to handle and stage on a wall. |
| Trim & fascia boards | Smooth finish, various widths | Window and corner trim, fascia replaced alongside gutters | Pairs naturally with a gutter replacement when fascia is already exposed. |
| Soffit panels | Vented or non-vented sheet stock | Attic ventilation upgrades done alongside a roof or siding job | Vented panels only help if the attic's intake and exhaust are actually balanced behind them. See roofing for how we check that. |
On cost versus longevity: fiber cement runs higher than vinyl in both material and labor, largely because of the weight and the cutting precautions above. What that cost buys is a board that does not crack from cold the way brittle old PVC can, holds paint far longer than wood, and is non-combustible, which some insurers take into account. It is a longer-term bet, and a fair one, but it is not the cheapest way to reside a wall on the day of installation.
How a fiber cement job runs at your house
- Free inspection. We assess the existing wall, note whether old siding needs tear-off first, and confirm the framing can take fasteners at the spacing this material needs.
- Written scope. Format, texture, factory or field finish, and trim details named as line items.
- Delivery and staging. Pallets are heavy. We plan where they land and how boards move to the wall without over-handling them.
- Tear-off and house wrap, if needed. Old siding removed, sheathing checked, new water-resistive barrier installed before any board goes up.
- Cutting and installation. Dust-controlled cutting on site, corrosion-resistant fasteners driven into framing at the manufacturer's spacing, gaps left at butt joints for the board's own slight movement.
- Caulk and touch-up. Joints sealed, cut edges primed or painted to match before the job is called finished.
- Cleanup and walk-through. Wet cleanup of any cutting debris, haul-off, and a walk around the house with you.
Warranty: what's covered on a siding job
We don't carry a separate workmanship warranty specific to siding installation. What we do have confirmed: a 2-year workmanship warranty on interior and exterior paint, a 2-year workmanship warranty on gutter and gutter guard installation, and a 5-year workmanship warranty on roofs. Any warranty on the fiber cement board itself, including factory-finish coating warranties, comes from the manufacturer, not from us. See the full warranty breakdown for how our paint, gutter and roofing coverage works.

Fiber cement siding: the rear elevation
What homeowners ask us about fiber cement siding.
Field-primed boards need paint from the start. Factory-finished boards hold their coating for many years, but no exterior coating lasts forever, and eventually a repaint is the right move rather than a replacement. See exterior painting for how we prep a fiber cement wall when that day comes.
Almost never a structural issue. Homes carry far more dead load than a layer of siding. The weight changes how our crew stages and fastens the material, not whether your walls can support it.
We cut with vacuum-equipped saws or with shears and the score-and-snap method, both of which keep dust well below what a dry cut with a standard blade throws off, following OSHA's silica rule for the trade. Cut debris is cleaned up wet, never dry-swept.
No. Fiber cement needs a flat, nailable surface and correct fastener penetration into framing, which an old vinyl wall doesn't provide. That means a proper tear-off first. See vinyl siding replacement for what that process looks like.
Fiber cement is cement-based, heavier, and typically factory-finished. LP SmartSide is engineered wood, lighter, and easier to cut without silica precautions, but it needs more diligent caulking and paint maintenance over time since it's wood-based. Which one fits depends on the house and the look you want.
Yes, across Boone County and into the north Indianapolis metro, including Carmel, where we see a good mix of new-construction fiber cement and older homes converting away from vinyl.

Yes to both. Fiber cement jobs start with 50% down, which orders material and holds your spot on the schedule, and the balance is due once the job is finished and you have walked it with us. Financing is available on larger siding projects, so ask us about options when we come out.
