Lynden Siding One Product, One Standard
We get asked fairly often why we don't offer a menu of siding options. Most contractors carry two or three brands and let the homeowner pick based on budget. We used to think about it that way too, until we spent enough years repairing and replacing siding around Lynden and the rest of Whatcom County to see which products actually held up and which ones didn't age well on our houses. At this point we install James Hardie fiber cement siding exclusively. Not because of a dealer incentive or a marketing relationship, but because it's the only product we've found that consistently performs against this specific climate without turning into a maintenance project five or ten years down the road.
What Makes Our Climate Hard on Siding
Lynden sits inland from Bellingham Bay, but we still get salt-laden air moving in off Puget Sound, mixed with the driving, sideways rain that comes through Whatcom County in the fall and winter. Add a moss season that runs long and shows no mercy to anything with a horizontal ledge or a shaded north wall, and you've got a climate that tests siding in three ways at once: moisture intrusion, organic growth, and finish degradation from repeated wet-dry cycling. Wood-based products and some engineered composites are especially sensitive to that combination. Even well-built vinyl can warp, fade, or gap over time as it expands and contracts through our temperature swings and wind-driven rain events.
Why Fiber Cement Wins This Fight
James Hardie siding is made from cement, sand, and cellulose fiber, cured into a dense, stable board. It doesn't absorb water the way wood-based siding does, it won't feed rot or fungal growth the way organic substrates can, and it holds its shape through wet winters and dry summers without the expansion and contraction problems that plague vinyl. It's also non-combustible, which matters more every fire season in the Pacific Northwest and is something we take seriously when we're specifying materials for a client's home.
Built for Regions Like Ours
Hardie engineers its products by climate zone, and the HZ5 line is formulated for regions with the kind of moisture exposure Whatcom County deals with all winter. That's not a marketing label — it reflects a different formulation than the versions sold in dry, arid states. When we spec Hardie for a home in Lynden, we're specifying the version actually built for our weather, not a generic national product.
ColorPlus: The Finish Matters as Much as the Board
A lot of siding failures we've been called out to inspect aren't really material failures — they're finish failures. Paint peels, caulk fails at the seams, and moisture gets behind the cladding. Hardie's ColorPlus finish is baked on at the factory under controlled conditions, with more coating layers than a field-applied paint job can achieve. It resists fading and chipping far longer than site-painted siding, and because it's factory-controlled, the color is consistent across every board on the house. That matters on a long lap run where inconsistent color really stands out.
The Warranty Reflects Real Confidence
Hardie backs its siding with a strong transferable limited warranty, and the ColorPlus finish carries its own separate finish warranty. A warranty is only worth something if the manufacturer is confident the product will actually perform for that long — and Hardie's track record in wet climates gives us that confidence when we put our name on a job.
What Correct Installation Actually Requires
None of this matters if the siding goes up wrong. Fiber cement is installation-sensitive: proper clearances above grade and roof lines, correct fastener spacing and type, weather-resistive barrier and flashing details at every penetration, and factory-recommended gaps at butt joints and trim. We install to Hardie's published specifications every time, not as an upsell but as the baseline. A lot of the siding problems we get called to look at aren't product problems — they're installation shortcuts that show up years later as moisture damage.
The Lines We Install
- HardiePlank lap siding — the most common choice, available in multiple textures and exposures
- HardiePanel vertical siding — often used for board-and-batten looks or accent sections
- HardieShingle — for a shaped, staggered look without the moisture issues of wood shakes
- HardieTrim — matched trim boards for a consistent, factory-finished look at corners and openings
Why We Don't Offer Alternatives
We know some homeowners want a lower up-front cost option, and there are legitimate products on the market that serve certain budgets and applications well. We simply don't install them. When we stand behind a job in Lynden's climate, we want to be confident it'll still look right in fifteen years, not just at the final walkthrough. Standardizing on one system lets our crews get genuinely expert at the installation details that make the difference, instead of splitting attention across several product lines with different rules.
