Anacortes Siding Two Fiber Cement Brands, One Choice for Anacortes Homes
Homeowners researching siding replacement in Anacortes often come across Cemplank and assume it's simply a cheaper version of James Hardie. That's not quite right. Cemplank is a legitimate fiber cement product made by a different manufacturer, and on paper it competes in the same category: non-combustible, dense, resistant to rot in ways that wood siding never will be. We get asked often enough why we install one and not the other that it's worth laying out the real differences honestly, rather than just saying "trust us."
What Cemplank Gets Right
Cemplament is fiber cement, which means it shares the core advantages of the category over wood, vinyl, or LP SmartSide: it doesn't feed insects, it holds paint far better than wood, and it stands up to the kind of driving rain that blows off Fidalgo Bay through the fall and winter. As a raw material, it's a reasonable product. Our concerns aren't with the cement board itself — they're with everything built around it.
Where the Two Products Diverge
| Factor | Cemplank | James Hardie |
|---|---|---|
| Factory finish system | Limited factory-finish color options in this region | ColorPlus baked-on finish, wide regional color range |
| Climate-specific engineering | General-purpose formulation | HZ5 product line engineered for Pacific Northwest moisture cycles |
| Local dealer and distribution support | Inconsistent availability of matching trim, panel, and touch-up stock in Skagit County | Established regional distribution and installer training network |
| Warranty structure | Manufacturer warranty, less commonly transferable in our experience | Non-prorated warranty on the finish, transferable to a new owner |
| Installer familiarity | Fewer local crews trained on brand-specific fastening and joint details | Widely used product with well-documented installation standards |
Why the Finish System Matters Here
Anacortes sits close enough to the water that salt air is a real factor on siding, especially on homes facing the bay or exposed to wind off the Sound. A factory-applied finish that's actually engineered to resist that kind of exposure, rather than a standard-issue paint job, makes a measurable difference over ten or fifteen years. When a finish is applied at the factory under controlled conditions, it cures more evenly and adheres more consistently than field-applied paint ever will. That's true of any well-made factory finish system in theory — but we've found the depth and regional tuning of Hardie's ColorPlus lineup gives us more confidence putting our name behind it on a house that's going to face Skagit County's rain, humidity, and long moss season year after year.
Moisture Behavior and Moss Season
Fiber cement in general handles moisture better than wood, but "handles moisture better than wood" is a low bar. What actually matters here is how a specific product's joints, caulking recommendations, and panel design perform through our extended wet season — typically October through May, with moss and algae growth setting in on shaded, north-facing walls that stay damp for weeks at a time. Hardie's HZ5 line was developed with input from installers in wet regions like ours, and the installation details (starter strips, flashing, panel gaps) are documented specifically for that climate zone. We haven't found the same depth of climate-specific documentation and regional installer support behind Cemplank, which matters more than most homeowners realize until year eight or nine, when small installation shortcuts start showing up as caulk failure or moisture staining.
Warranty and Resale
Warranty terms matter less on paper than they do the day something actually goes wrong, or the day you list your house for sale. A non-prorated, transferable warranty on both the substrate and the factory finish is a meaningful selling point for a buyer's inspector and a meaningful protection for you. We've found Hardie's warranty documentation and claims process more consistent and better recognized by appraisers and inspectors in this region, which is a practical concern, not a brand preference.
Why We Standardized on One Product
We made a decision a while back to install James Hardie exclusively rather than carrying multiple fiber cement brands. It's simpler for us to explain: we know the fastening schedules, the flashing details, the color options, and the warranty terms for one system inside and out, rather than switching between products and risking a detail that works for one brand but not another. For a climate that includes salt air, sideways rain, and months of damp shade every year, we'd rather install fewer products extremely well than several products adequately.
What This Means for Your Project
If you're comparing quotes and one contractor is offering Cemplank at a lower price, that's worth understanding clearly rather than dismissing — it may be a perfectly serviceable product for the right situation. But for Anacortes and the rest of Skagit County, where siding has to survive marine exposure and a long wet season decade after decade, we've chosen to put our reputation behind the product and finish system we trust most.
