Lynden One Product, One Standard
We get asked about this a lot: why does a siding contractor limit itself to a single manufacturer? Most contractors in Whatcom County will install whatever the homeowner picks — vinyl, LP SmartSide, cedar, whatever's cheapest that week. We stopped doing that years ago. We install James Hardie fiber cement siding, and that's it. Not because we get a kickback for saying so, but because after years of tear-offs, warranty calls, and callbacks on other products, Hardie is the only siding we're willing to put our name on.
What Lynden's Weather Actually Does to Siding
Whatcom County isn't a brutal climate on paper, but it's a relentless one. Lynden sits close enough to the Salish Sea to catch salt-laden air moving in off the coast, and the Nooksack lowlands trap moisture for months at a stretch. Add driving rain off the Pacific storm track, a moss and mildew season that can run eight or nine months a year, and freeze-thaw cycles in the winter, and you have a set of conditions that punishes any siding material with a weak spot for moisture, rot, or UV breakdown. Products that look fine in a showroom or in a drier climate often show their limitations here within five to ten years.
Why We Walked Away From the Alternatives
We're not going to tell you every other siding product is junk — that's not honest, and it's not our place. Each one has a legitimate use case. Here's the plain-English version of what pushed us to standardize on Hardie:
- Vinyl siding is inexpensive and low-maintenance, but it expands and contracts significantly with temperature swings, can warp or fade over time, and isn't repairable in the way fiber cement is — a damaged panel usually means a full replacement of that section, and matching older color runs gets harder every year.
- LP SmartSide is an engineered wood product, and engineered wood, by definition, needs its edges and seams sealed correctly and kept sealed. In a climate with this much sustained moisture exposure, that installation margin for error is thin, and the long-term performance depends heavily on maintenance follow-through from the homeowner.
- Cedar and primed spruce are beautiful, and we understand the appeal. But real wood siding in a wet coastal climate means an ongoing commitment to refinishing, caulking, and moisture monitoring that most homeowners underestimate when they choose it.
- Cemplank and Allura are also fiber cement, and structurally they're in the same family as Hardie. Our reasoning here is less about the raw material and more about finish consistency, factory quality control, and the strength of the warranty and support network behind the product over a 30-plus year service life.
In every case, the trade-off isn't that the product fails outright — it's maintenance burden, installation sensitivity, or long-term appearance that made us stop recommending it for this specific climate.
What James Hardie Gets Right
Hardie fiber cement is cement, sand, and cellulose fiber — it doesn't rot, it doesn't feed moss the way wood fiber can, and it's non-combustible, which matters given wildfire smoke seasons are now a regular part of Pacific Northwest summers. James Hardie also engineers specific product lines for specific climates. The HZ5 line is built for regions with prolonged moisture exposure and freeze-thaw cycling — exactly what Lynden sees most winters.
ColorPlus Factory Finish
Most siding failures we see aren't the substrate — they're the paint. Field-applied paint on any siding material is only as good as the weather conditions on the day it was sprayed and the prep work underneath it. Hardie's ColorPlus finish is baked on in a controlled factory environment, cured to resist fading and chipping, and backed by its own finish warranty separate from the substrate warranty.
Product Lines We Install

|---|---|
| HardiePlank Lap Siding | Traditional lap look, most common residential application |
| HardieShingle | Shingle-style accents and full facades |
| HardiePanel | Board-and-batten and modern vertical looks |
| HardieTrim | Corner boards, fascia, and window trim to match |
Installation Is the Other Half of the Equation
Fiber cement is only as good as its installation. Correct fastener placement, proper clearance from grade and roof lines, factory-cut edges sealed where required, and correct flashing details all matter more in a wet climate than a dry one. A misaligned installation can void the manufacturer's warranty regardless of the product quality — which is exactly why we treat installation training as seriously as product selection.
The Warranty Difference
James Hardie backs its products with a non-prorated, transferable limited warranty — meaningful protection for a homeowner who may sell the house before the siding's functional life is up. That warranty, paired with a proven manufacturer track record across decades of Pacific Northwest installations, is a big part of why we stopped hedging our bets on other materials.
