Chuckanut Exterior One Product, On Purpose
We get asked fairly often why we don't offer a menu of siding brands the way some contractors do. The honest answer: we used to look at all of them, and after years of installing and repairing siding around Chuckanut and greater Whatcom County, we standardized on one manufacturer — James Hardie. Not because it's the cheapest option, and not because of a dealer incentive. Because it's the product that consistently holds up to what this part of Washington throws at a house.
What Our Climate Actually Does to Siding
Chuckanut sits close enough to the water that salt-laden air is a real factor, not a theoretical one. Add in driving rain off the Sound, long stretches of gray, damp weather, and a moss season that can run half the year on shaded north-facing walls, and you've got a punishing combination for exterior materials. Siding here doesn't just need to look good on installation day — it needs to resist moisture intrusion, swelling, delamination, and constant biological growth for decades, without babysitting from the homeowner.
That's the filter every product has to pass before we'll put our name on the install. Several common options don't clear it well enough for us to stand behind.
Why We Passed on the Alternatives
Vinyl
Vinyl is inexpensive and easy to install fast, and in drier climates it can do fine. In our conditions, it expands and contracts more than fiber cement, seams can telegraph over time, and it offers no real fire resistance. It also tends to show its age — chalking and fading — sooner than homeowners expect, especially on sun-exposed elevations near the water.
LP SmartSide
Engineered wood has improved a lot over the years, and LP SmartSide is a legitimate product. But it's still wood-based, which means its long-term performance depends heavily on unbroken paint film and flawless edge sealing. In a region with our rainfall totals and humidity, any lapse in maintenance — a scratch, a poorly caulked joint, a missed touch-up — opens the door to moisture and swelling. We didn't want to build a business around a product that punishes small maintenance gaps this severely.
Cemplank and Allura
These are also fiber cement, and fiber cement as a category is the right technology for this climate. Our issue isn't the material chemistry — it's factory finish quality, color-line consistency, and warranty structure over the long haul. James Hardie's ColorPlus finishing process and its national scale give us more confidence in consistent results and in a warranty that actually means something ten or twenty years from now.
Primed Spruce and Cedar
Solid wood siding has real appeal — it's a classic, honest look, and cedar in particular has natural rot resistance many people love. But both require a repainting or re-staining cycle that, honestly, few homeowners keep up with on schedule. In a moss-prone, moisture-heavy environment, gaps in that maintenance show up fast as cupping, checking, and rot at butt joints. We've replaced too much failed wood siding to keep installing more of it in good conscience.
What Hardie Gets Right
James Hardie fiber cement is non-combustible, which matters more each year as wildfire smoke and ember exposure become a bigger part of Pacific Northwest summers. It doesn't feed insects or rot the way wood-based products can. It holds paint and factory finish far longer than primed wood, and Hardie's HZ5 product line is engineered specifically for climates like ours — freeze-thaw cycling, prolonged moisture exposure, and coastal air.
The ColorPlus finish is baked on at the factory under controlled conditions, which gives more even color and better fade resistance than field-applied paint. Hardie also backs its siding with a strong, transferable limited warranty — a real consideration if you sell the home before the siding's service life is up.
Installation Still Matters
None of this works if the install is sloppy. Fiber cement performs the way it's supposed to only when clearances, fastening, joint treatment, and caulking are done to Hardie's spec. That's a big part of why we limit ourselves to one product — it lets our crews get genuinely expert at installing it correctly, every time, rather than spreading that expertise thin across five different systems.
Our Bottom Line
We're not going to tell you every other siding product is junk — that's not fair, and it's not true. What we will tell you is that after weighing moisture behavior, fire resistance, finish durability, and long-term maintenance against what Chuckanut's salt air, rain, and moss season demand, James Hardie is the product we're willing to warranty our workmanship on. It's the one system we trust completely, so it's the only one we install.
