Everett Two Fiber Cement Products, One Real Difference
Most homeowners researching siding eventually learn that fiber cement, as a category, is a smart material choice for the Pacific Northwest. It resists rot, holds up to moisture, and doesn't attract the insects that go after wood siding. What a lot of people don't realize is that "fiber cement" isn't one product — it's a category with several manufacturers competing in it, and Cemplank is one of the names you'll run into alongside James Hardie. Both start from the same basic recipe of cement, sand, and cellulose fiber. That's about where the similarity ends.
We install James Hardie exclusively. We don't install Cemplank, LP SmartSide, vinyl, or any of the other siding products on the market, even though several of them are reasonable materials in the right hands. This page explains where Cemplank holds its own, where the two products diverge in ways that matter over the life of a Snohomish County home, and why we standardized on one product rather than offering several.
What Cemplank Gets Right
Cemplank is a legitimate fiber cement product, not a cut-rate imitation. It's manufactured to the same general category standards as other fiber cement siding — non-combustible, dimensionally stable, and far more durable against moisture than wood, LP, or vinyl. For homeowners and contractors comparing fiber cement options primarily on upfront material cost, Cemplank is often priced a step below James Hardie, and it's distributed through a number of the same building material suppliers contractors already buy from.
It's also worth being fair here: there are contractors who install Cemplank competently and homeowners who've had it on their houses for years without major issues. The core material — fiber cement board — is a sound category to build with in a wet, marine climate like ours. Our decision isn't a judgment that Cemplank is unusable. It's that when we compared the two products side by side against what Everett and Snohomish County weather actually do to a house over 20-plus years, one product's engineering and support system gave us more confidence than the other.
Where the Two Products Diverge
Factory Finish Technology
This is the biggest practical difference for a homeowner living with the siding day to day. James Hardie's ColorPlus finish is baked on in a factory-controlled process specifically engineered to resist UV fading, chipping, and cracking, and it carries its own separate finish warranty apart from the substrate warranty on the board. Other fiber cement brands, including Cemplank, offer factory-primed or factory-finished options as well, but the finish technology, application process, and warranty backing behind it vary by manufacturer — and that variation is exactly the kind of detail that's easy to gloss over in a sales conversation but shows up on the wall ten years later as chalking, fading, or uneven color between original siding and any patched-in repairs.
Cut-Edge and Field Treatment
Every fiber cement installation involves field cuts — around windows, doors, corners, and utility penetrations — and every cut edge exposes raw, unfinished board that needs to be sealed or treated according to the manufacturer's specification. James Hardie publishes a specific, detailed protocol for treating cut edges and provides touch-up products engineered to match ColorPlus finishes. How thoroughly a crew follows that protocol matters more than which brand of board is on the wall, but it only works if the manufacturer has actually engineered a matching system for it. This is a case where the material and the installation standard are tied together, not separate questions.
Warranty Structure
Warranty length and terms differ by manufacturer and have changed over time for both brands, so we won't quote specific numbers here — that's a conversation to have directly with any siding company, in writing, before you sign a contract. What we will say is that warranty terms are worth reading closely rather than taking on faith: check whether the warranty is prorated over time, whether it transfers to a new owner if you sell the home, and whether the finish is warrantied separately from the board itself. Ask the same three questions of any siding product you're considering, Cemplank or Hardie included.
Dealer and Installer Network
James Hardie runs a certified contractor program with training requirements, and the company has a long track record and a large enough installed base in the Puget Sound region that matching materials, trim, and touch-up products years after the original install is generally straightforward. That kind of long-term parts and support availability is a real, practical consideration in a region where houses commonly sit through 30-plus years and multiple owners.
What James Hardie Brings to a Snohomish County Home
Everett sits close enough to Puget Sound that salt-laden air is a real factor on siding, not a theoretical one, and the driving rain that comes through in a fall or winter storm system tests every seam, joint, and cut edge on a house. On top of that, this region gets a long stretch of the year — often eight months or more depending on the winter — where walls simply don't dry out fully between rain events, which is exactly the environment moss and algae need to take hold.
James Hardie engineers specific product lines for climate zones, and the HZ5 line is built for regions like ours: cold, wet, and prone to repeated moisture cycling rather than a single dry season followed by a single wet one. The board itself doesn't expand and contract the way vinyl or wood-based siding does, so it holds its shape and its fastening over time. Combined with the ColorPlus finish and a clearly documented installation and cut-edge protocol, it's a system where the manufacturer has done real engineering work specifically for climates like Snohomish County's, not just a general-purpose fiber cement board sold everywhere the same way.
Side-by-Side Comparison
| Factor | Cemplank | James Hardie |
|---|---|---|
| Base material | Cement, sand, cellulose fiber | Cement, sand, cellulose fiber |
| Climate-specific engineering | General fiber cement offering | Zone-specific lines (e.g. HZ5 for cold, wet climates) |
| Factory finish | Factory-primed/finished options vary by product | ColorPlus baked-on finish with separate finish warranty |
| Cut-edge treatment system | Standard fiber cement sealing practice | Manufacturer-specified protocol with matched touch-up products |
| Certified installer network | Varies by region and distributor | Formal certified contractor program |
| Parts/trim availability long-term | Dependent on regional distribution | Broad, established installed base in Puget Sound region |
| Typical upfront material cost | Often priced below Hardie | Higher, reflecting finish and engineering |
| Warranty transferability | Read terms directly — varies | Read terms directly — generally structured to transfer to new owner |
Installation Sensitivity — Why the Crew Matters as Much as the Board
No fiber cement product performs well installed carelessly. Wrong fastener placement, unsealed cut edges, improper clearance from grade or roof lines, and poor flashing at penetrations will cause problems regardless of which brand's name is on the box. The difference is that a manufacturer with a detailed, published installation manual and a certified installer program gives a crew a clear standard to be held to — and gives a homeowner something concrete to ask about before hiring.
We made the call years ago to install one product exceptionally well rather than stock several brands and spread our crews' expertise across all of them. Every siding call-back or repair we've been brought in on traces back to either the wrong material for the site's exposure, or a reasonable material installed without following the manufacturer's specification — rarely one without the other. Specializing in a single, well-documented system is how we keep that from happening on our own work.
Cost Considerations Over the Ownership Period
Cemplank's lower upfront material cost is real and worth acknowledging plainly. But the comparison shifts once you look past day one:
- Finish longevity: a factory finish engineered and warrantied specifically for fade and chip resistance tends to need repainting less often than a general-purpose fiber cement finish
- Repair matching: replacing a damaged panel years later is easier when the manufacturer has a large, consistent regional installed base and matched touch-up products
- Maintenance in a wet climate: Everett's long damp season means whatever's on your walls will need periodic washing to stay ahead of moss and algae — ask how any product's finish holds up to that cleaning over repeated cycles
- Resale recognition: James Hardie is widely recognized by buyers and appraisers as a premium, durable siding brand, which can carry weight at resale
What to Ask Any Contractor Before You Choose a Fiber Cement Brand
- Is the finish factory-applied or field-applied, and is it warrantied separately from the board?
- What's the manufacturer's published protocol for treating field-cut edges, and will the crew actually follow it?
- Is the warranty prorated, and does it transfer to a new owner if the home sells?
- Is this crew certified or specifically trained on the exact brand they're proposing to install?
- How available are matching trim, touch-up paint, and replacement panels for this brand five or ten years from now?
- What does this brand's installed base look like in Snohomish County specifically — has this crew worked with it repeatedly here?
Why We Standardized on Hardie
Both Cemplank and James Hardie start from the same basic fiber cement recipe, which is why the decision isn't about ruling out a bad material — it's about which manufacturer's engineering, finish technology, and installer support system gave us the most confidence for homes that have to stand up to Everett's salt air, driving rain, and a moss season that rarely lets up. James Hardie's zone-specific product lines, factory ColorPlus finish, and long track record in the Puget Sound region are why we put our name behind installing it, and only it.
