Everett An Honest Look at Cemplank
Homeowners in Everett occasionally ask us to bid a job using Cemplank, and we understand why. It's fiber cement, it's sold at a lower price point than the products we install, and on paper it checks a lot of the same boxes as James Hardie siding: noncombustible, resistant to rot, and more durable than vinyl. We don't want to dismiss that. Cemplank is a real fiber cement product, not a knockoff, and for some homeowners and some budgets it's a reasonable choice. It's just not what we put on a house.
Why We Passed on It
Our decision isn't about one dramatic flaw. It's a handful of smaller trade-offs that add up once you factor in what a house in Snohomish County actually deals with over 20 or 30 years.
The Finish Is the Real Product
Fiber cement siding is only as good as the finish baked onto it. Cemplank is typically sold as a primed substrate meant to be field-painted, or with a lighter factory coating than what we prefer to work with. That matters here more than it does in a dry climate. Everett sits close enough to Puget Sound that salt-laden air is part of daily weather, and between that and our long stretch of gray, wet winters, a field-applied paint job has to fight harder to hold its seal at every cut edge, nail head, and butt joint. We've seen what happens when a coating that wasn't engineered specifically for fiber cement starts to chalk or lift a few years in — it's not a catastrophic failure, but it does mean repainting sooner than the homeowner expected, and repainting siding at height on a two-story home isn't cheap.
Moss and Algae Season Is Long Here
Snohomish County doesn't really have an off-season for moss and algae growth. Anything facing north, shaded by trees, or tucked under an eave stays damp for weeks at a time between fall and spring. A siding finish with a strong factory-baked topcoat sheds that growth and pressure-washes clean far more reliably than a standard primed or lightly coated surface, which tends to hold moisture in its texture and give algae something to grip. Over a full moss season, that difference shows up as a maintenance schedule — how often the homeowner is up there scrubbing or repainting — not as a one-time cosmetic issue.
Consistency and Warranty Structure
Because Cemplank is distributed through big-box and general building supply channels rather than through a dedicated contractor network, we've found it harder to guarantee batch-to-batch consistency in thickness, color match on repairs, and trim availability down the road. If a board gets damaged five years after installation, matching it exactly matters for how the whole wall reads. We also weigh warranty structure heavily — not just the number of years printed on paper, but whether it's backed by a national manufacturer with a track record of standing behind fiber cement specifically, and whether it transfers cleanly if the home is sold. That's a real factor for resale in a market like Everett's.
What We Install Instead
We install James Hardie fiber cement exclusively, and specifically the HZ5 product line engineered for northern, wetter climates like ours. A few reasons that's where we landed:
- ColorPlus Technology — a factory-baked, multi-coat finish that resists fading, chipping, and moisture intrusion far better than field paint, and holds up against the salt air common along the Sound and driving rain off the water.
- Climate-engineered formulation — HZ5 is built for the freeze-thaw cycles, humidity, and rain exposure typical of Western Washington, not a one-size-fits-all national formula.
- Noncombustible core — genuine fire resistance, which matters more each year with regional wildfire smoke and ember exposure even outside dense forest zones.
- A real, transferable warranty — backed by the manufacturer, which protects the homeowner's investment if the home changes hands.
- Consistent supply and matching trim — so a repair five or ten years down the line doesn't turn into a mismatched patch job.
The Bottom Line
Cemplank isn't a bad product in the abstract — it's fiber cement, and fiber cement is a good category of siding. But once you factor in what a house in Everett actually endures — salt air off the Sound, driving rain in from the water, and a moss season that runs most of the year — we decided the finish quality, climate-specific engineering, and warranty backing of James Hardie were worth standing behind as our only siding product. We'd rather install one system well than offer a menu of options we can't fully vouch for over the long haul.
