Orcas Island Siding One Product, One Standard
We get asked fairly often why we don't offer a menu of siding brands the way some contractors do. The honest answer is that we decided years ago to stop installing anything other than James Hardie fiber cement siding, and we haven't looked back. Not vinyl. Not LP SmartSide. Not Cemplank or Allura. Not primed spruce or cedar. This page explains the reasoning, because we think homeowners on Orcas Island deserve a straight answer rather than a sales pitch.
What Orcas Island Actually Does to Siding
San Juan County living is beautiful, but it's hard on a house exterior. Salt air off the water accelerates corrosion and finish breakdown. Driving rain off the Sound finds every gap and seam. And our long, damp moss season keeps siding wet for weeks at a stretch, which is exactly the condition that rewards a moisture-stable material and punishes anything that swells, delaminates, or feeds mold. We've walked enough Orcas Island homes to see which products hold up under those conditions decade after decade and which ones need constant attention.
Why We Stopped Installing Wood, Vinyl, and Engineered Wood Products
Cedar and primed spruce are genuinely handsome materials, and there's nothing wrong with liking that look. The trade-off is maintenance: wood siding in a marine, moss-heavy climate needs regular repainting or staining, careful caulking, and vigilant moisture management, or rot sets in at butt joints and lower courses. Engineered wood products like LP SmartSide improve on solid wood in some ways, but they're still wood-based and rely on factory treatment and an intact paint film to resist moisture — any breach in that film, and the substrate is vulnerable to swelling and edge deterioration, especially in a climate that stays wet as long as ours does.
Vinyl siding is low-maintenance and inexpensive, which is a real advantage for some budgets. But it's a combustible plastic product that can warp or become brittle over time, it has visible seams and limited color depth, and it simply doesn't hold up in a coastal aesthetic the way a heavier, factory-finished material does. It's a fine product for some regions. We don't think it's the right long-term investment for homes exposed to the wind and salt air here.
Where Cemplank and Allura Fit
Cemplank and Allura are also fiber cement, and fiber cement as a category is sound — that's precisely why we build our business around it. But we standardized on one manufacturer rather than installing whichever fiber cement board is cheapest that month, and James Hardie is the one whose engineering, factory finish, and warranty structure we trust most for this specific climate. Consistency in product, installation detail, and warranty administration matters more to us than flexibility in brand.
Why James Hardie
Non-Combustible Core
Hardie fiber cement is engineered from cement, sand, and cellulose fiber. It does not burn, which matters increasingly to insurers and to homeowners thinking about wildfire exposure even out here in the islands.
Climate-Engineered HZ Product Lines
James Hardie manufactures HZ5 boards specifically formulated for regions with more moisture and temperature swing exposure — the kind of climate profile the Pacific Northwest and San Juan County present. That's an actual engineering response to regional weather, not a marketing label.
ColorPlus Factory Finish
Instead of field-applied paint that starts breaking down against salt air and UV within a few years, ColorPlus finish is baked on in a controlled factory process, resists fading, and comes with its own finish warranty separate from the substrate warranty. Fewer repaints over the life of the siding is a real cost savings, not just convenience.
Warranty Structure
Hardie backs its products with a strong transferable limited warranty on the substrate, plus a separate ColorPlus finish warranty. That transferability matters on Orcas Island, where homes change hands and buyers want documented, honest maintenance history on the exterior.
Installation Is the Other Half of the Equation
Fiber cement only performs as engineered when it's installed to Hardie's published specifications — proper clearances, fastener patterns, flashing details, and joint treatment. A great product installed carelessly will still have problems. We install exclusively to spec because we've seen what happens when siding is installed to guess-work rather than manufacturer detail, especially in a wet climate that doesn't forgive shortcuts.
Our Bottom Line
We're not going to tell you other siding products are junk — plenty of them are reasonable choices somewhere. But for the specific combination of salt air, driving rain, and moss season that defines exterior life on Orcas Island, we've made a professional decision to install one product, correctly, every time, rather than offer a catalog of compromises. That's why James Hardie is the only siding on our trucks.
