Noncombustible
Fiber cement will not ignite, which helps near wildland edges, close neighbors and backyard fire features.
Fiber cement siding installation
Fiber cement siding in Seattle and the Puget Sound
Durable, noncombustible and at home in a wet climate. Here is what fiber cement siding costs, how it is installed correctly and why it is one of the most common choices for long-term Puget Sound homeowners.
Built for rain
Why fiber cement siding suits the Northwest
Fiber cement siding is made from cement, sand and cellulose fibers pressed into planks, panels and shingles. It does not rot, insects do not eat it, and it will not burn. For fiber cement siding in Seattle, that combination matters: the boards stay dimensionally stable through months of damp weather, and they hold paint far longer than wood does. James Hardie is the best-known brand, and several other manufacturers make similar products; we install to the specification of whichever product you choose.
Fiber cement siding installation, step by step
Fiber cement is heavy and unforgiving, which is why installation quality shows. On a typical project we:
- Remove the old siding and inspect the sheathing, replacing any soft or rotted areas.
- Install a weather-resistive barrier and, where the wall design calls for it, a rain-screen gap so the back of the boards can dry.
- Flash windows, doors, penetrations and the roof-to-wall joints, including kick-out flashing where a roof edge meets a wall.
- Keep the required clearances above soil, patios and roofs, since the bottom edges should not sit in water.
- Seal or prime field-cut edges and fasten with the nail type and spacing the manufacturer requires.
Cutting fiber cement creates silica dust, so our crews cut outdoors with dust-reducing saws and follow safe work practices around your home.
Pre-finished or field painted
Many fiber cement products come with a baked-on factory finish in a set palette of colors. That finish is consistent, and it removes a separate paint phase from the schedule. Primed boards cost less for material and let you choose any color, but they need to be painted soon after installation. Either way, plan on repainting every 10–15 years, often longer for factory finishes on protected walls.
Styles
Lap siding in smooth or wood-grain texture is the workhorse. Shingle panels suit Craftsman gables, vertical panels with battens suit modern farmhouse designs, and large smooth panels suit contemporary homes. Mixing profiles is common. To compare budgets, see vinyl siding and LP SmartSide, or start with the siding materials guide.

How this material compares on cost
Typical Puget Sound installed ranges per square foot of wall — removal of one layer, weather barrier and standard trim included.
- Vinyl $26.0k–$43.4k : $9 to $15 per square foot installed
- LP SmartSide $31.8k–$52.1k : $11 to $18 per square foot installed
- Fiber cement $37.6k–$60.8k : $13 to $21 per square foot installed
- Cedar $46.3k–$81.0k : $16 to $28 per square foot installed
Pros and what to know
Strengths and trade-offs of fiber cement
Rot and pest resistant
The cement-based boards resist rot and fungus and hold no appeal for woodpeckers or carpenter ants.
Crisp, stable lines
Boards do not expand and contract much, so paint lines and joints stay tight for years.
Heavier and slower to install
More labor per square foot than vinyl or engineered wood, which is part of the higher installed price.
Paint is still required
Factory finishes last longer than site paint, but the siding will need repainting over its life.
Details decide the result
Clearances, kick-out flashing and sealed cut edges prevent the moisture problems seen on poor installs.
Worked cost example
Fiber cement cost on a 2,200 sq ft Bellevue home
Fiber cement is popular on the Eastside, where many HOAs favor it, so here is a planning range for a two-story Bellevue home with 2,200 sq ft of living space.
- Wall area: 2,200 × 1.36 = 2,992 sq ft of wall.
- Installed rate: 2,992 × $13 = $38,896 low; 2,992 × $21 = $62,832 high.
- Bellevue factor: × 1.16 for local labor and access.
The result is a planning range of about $45,100–$72,900. For comparison, the same math on a 1,900 sq ft two-story house in Seattle (2,584 sq ft of wall × $13–$21 × 1.12) gives roughly $37,600–$60,800.
What moves the number
Primed lap siding with simple trim sits near the low end. Factory-finished boards, shingle gables, board-and-batten sections, a rain-screen system and lots of windows move it up. Hidden rot found after tear-off is priced separately once we see it. These are planning figures, not quotes; run your own numbers in the siding cost estimator or read about local conditions on our Bellevue siding page.
Is it right for you?
Fiber cement pros and cons in plain terms
Choose fiber cement if
- You plan to stay ten years or more and want siding that could outlast your mortgage.
- Fire resistance matters, or your HOA or design review prefers a painted, noncombustible material.
- Your walls take heavy weather, like a west-facing exposure or a lot with little tree cover.
Think twice if
- The budget only works with vinyl, and phasing the project is not an option.
- You want real wood grain and the character of stain; cedar siding may be a better match.
- You would rather never paint; vinyl is the only no-paint option.

Fiber cement questions
Fiber cement siding FAQ
Is fiber cement the same thing as Hardie board?
Hardie board is a common nickname taken from James Hardie, the best-known maker. Fiber cement is the general material, and several manufacturers produce it. Products differ in texture, finish options and warranty terms, so compare the specific product rather than the category.
Why does fiber cement need clearance above the ground and roofs?
The board edges can absorb water if they sit in splash zones or against roofing. Manufacturers specify minimum gaps above soil, hard surfaces and roof lines. Ignoring them is one of the most common causes of swelling and paint failure on fiber cement.
Does fiber cement crack?
It is rigid, so it can crack from a hard impact or if boards are fastened too close to the edge. Cracked boards can be replaced individually. Correct nailing and handling during installation prevent most cracking.
How long does a factory finish on fiber cement last?
Factory finishes are applied and cured in controlled conditions, so they typically outlast site-applied paint. Many manufacturers offer a separate limited warranty on the finish; terms vary by product and exposure.
Can fiber cement be painted a different color later?
Yes. Both primed and factory-finished boards can be repainted with a quality exterior acrylic after cleaning. Repainting is also the moment to renew caulk joints around windows and trim.
