Lynden Exterior One Product Line, One Reason: It Holds Up Here
We get asked fairly often why we don't offer a menu of siding brands the way some contractors do. The answer is simple: after years of installing and repairing siding across Lynden and the rest of Whatcom County, we standardized on James Hardie fiber cement and stopped installing everything else. This page explains what that means and why we think it's the right call for homes dealing with our specific climate — salt air drifting in off Drayton Harbor and the Strait, driving winter rain, and a moss season that can stretch from October well into spring.
What James Hardie Actually Is
James Hardie siding is fiber cement — a mix of cellulose fiber, sand, and cement formed into planks, panels, and shingles, then cured. It's non-combustible, dimensionally stable, and doesn't feed the moisture-related problems that plague wood-based and some engineered wood products in wet Pacific Northwest climates. It's not the cheapest siding on the market, and we're upfront about that. But it's built for exactly the conditions Lynden throws at a house year-round.
HZ5 Engineering for Our Climate
James Hardie makes climate-specific product formulations called HZ (HardieZone) products. HZ5 is engineered for regions that see freeze-thaw cycling and sustained damp conditions — which describes most of Whatcom County. The formulation and moisture management are matched to the actual weather a Lynden home experiences, not a generic national average.
ColorPlus Factory Finish
Most of what we install uses Hardie's ColorPlus finish — color baked on at the factory under controlled conditions, rather than field-painted after installation. This matters more here than in drier climates: field-applied paint has to cure properly to perform, and our rainy stretches don't always cooperate with a painter's schedule. A factory finish also gives a more consistent look across the whole house and typically holds color longer before it needs attention.
Product Lines We Install
- HardiePlank lap siding — the most common choice, available in several textures (smooth, cedarmill, beaded) and widths
- HardiePanel vertical siding — often used for board-and-batten looks or modern facades
- HardieShingle — for a shingle-style look without the maintenance burden of real cedar shingles
- HardieTrim — matching trim boards so the whole exterior system is consistent, not mixed materials aging at different rates
The Warranty, Honestly Explained
James Hardie backs its siding with a transferable limited warranty — a real advantage if a homeowner sells within the coverage period, since it's not tied to the original buyer only. ColorPlus finishes carry their own separate finish warranty. We'd rather explain this plainly than oversell it: warranty terms have conditions, including proper installation to Hardie's specifications. That's part of why we're strict about install method — a warranty is only as good as the installation behind it.
Why Installation Method Matters as Much as the Product
Fiber cement is unforgiving of shortcuts. Correct fastening patterns, proper clearances from grade and roof lines, correct flashing and water管理 behind the cladding, and manufacturer-specified gaps and caulking all affect how the siding performs over 20, 30, or more years. We install to Hardie's published specifications every time — not because it's required to make the siding look fine on day one, but because it's what determines whether the system still looks and performs well after a decade of Whatcom County winters.
What This Means for Homeowners in Lynden
Choosing a single, well-understood product system lets us do a few things well instead of many things adequately. We know the fastening schedules, the flashing details, the color options, and the failure points cold. When something goes wrong on a Hardie install, it's almost always an installation issue, not a product limitation — and that's a problem we can control and stand behind.
We're not going to pretend other siding products don't have their fans or their place. But for the specific combination of salt air, sustained rain, and moss pressure that defines siding performance in Lynden, we've made our decision and we're comfortable explaining it to anyone who asks.
