Bellingham Two Fiber Cement Products, One Standard
If you've been shopping for siding in Bellingham, you've probably run into more than one brand of fiber cement. Cemplank is one of them, and on paper it looks like a reasonable alternative to James Hardie. Both are cement-based composite sidings built from similar raw materials: Portland cement, sand, cellulose fiber, and water, pressed and cured into planks and panels. Both are non-combustible, resistant to rot, and far more durable than vinyl or untreated wood. We're not going to tell you Cemplank is a bad product. It isn't. But we made a decision years ago to install only James Hardie, and homeowners in Whatcom County deserve to know why before they sign a contract.
What Cemplank Gets Right
Fiber cement as a category earns its reputation. It doesn't feed carpenter ants or termites, it holds paint far longer than wood, and it stands up to the driving rain that rolls off the Salish Sea every fall and winter. Cemplank planks are manufactured to a real industry standard, and installed correctly, they'll outperform vinyl or engineered wood siding in almost every category that matters here. If you already have Cemplank on your home and it was installed properly, there's no reason to panic or assume it's failing. Our concern isn't with the raw material. It's with everything around it: the finish system, the product engineering for specific climates, and the support behind the product once it's on your wall.
Where the Real Trade-Offs Show Up
Factory Finish and Paint Warranty
This is the biggest gap. James Hardie's ColorPlus finish is a baked-on, factory-applied color system backed by a dedicated finish warranty that's separate from (and stacked on top of) the product warranty. Cemplank's factory finish options and the paperwork behind them are less standardized in our experience, and in a marine climate with year-round moisture and low winter sun, a weak finish system is where siding actually fails first — chalking, fading, and touch-up paint that never quite matches. We'd rather not gamble our customers' curb appeal on a finish warranty that's thinner than the one we can offer with Hardie.
Climate-Engineered Product Lines
Hardie builds region-specific formulations — its HZ5 line, for example, is engineered for the freeze-thaw and moisture cycling that's normal in the Pacific Northwest. That's not a marketing label; it changes how the board is formulated and how it's expected to perform over decades of Bellingham's wet falls, damp winters, and the long moss season that follows. We haven't seen Cemplank offer the same depth of climate-specific engineering, which matters more here than it would in a dry inland climate.
Installation Sensitivity and Local Support
Fiber cement in general is unforgiving of bad installation — improper flashing, wrong fastener placement, or tight caulked joints with no room to move will cause problems regardless of brand. Where Hardie pulls ahead is in the depth of installer training, technical documentation, and local dealer support we can lean on when we're detailing a tricky transition, a salt-air-exposed elevation, or a high-wind corner of a Whatcom County property. That backup matters when something needs to get resolved correctly the first time.
Resale and Warranty Transfer
James Hardie's warranty is transferable to a new owner, and Hardie board is a name most buyers and appraisers already recognize. That recognition has real value when a home eventually sells. Lesser-known fiber cement brands don't carry the same weight in a real estate inspection or appraisal, even when the underlying material performs fine.
Why We Standardized on Hardie
We don't install LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar. Not because every one of those products is defective, but because we'd rather stand behind one system we know inside and out — one with a finish warranty we trust, climate-specific engineering built for salt air and driving rain, and a track record long enough that we know exactly how it behaves on Whatcom County homes ten and twenty years in. That consistency is what lets us guarantee our installation work with confidence.
