One Product, No Exceptions
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 after years of installing and repairing siding around Fairhaven and the rest of Whatcom County, we settled on James Hardie fiber cement as the only product we'll put our name behind. Not because it's the cheapest option, and not because of any manufacturer incentive — it's because it holds up to the specific abuse this coastline throws at a house, and it's the one product where we can stand behind the installation for decades without second-guessing the material underneath.

What Makes Fiber Cement Different
James Hardie siding is made from cement, sand, and cellulose fibers, cured into planks and panels that are dimensionally stable and non-combustible. Unlike wood-based or engineered wood products, it doesn't swell, delaminate, or feed rot when it stays wet. Unlike vinyl, it doesn't soften in the sun or go brittle in a cold snap, and it won't warp off the wall. In a place like Fairhaven, where salt air off Bellingham Bay, driving winter rain, and a moss season that can stretch six months or more are just normal weather, that stability is the whole ballgame. Siding here doesn't fail because of one bad storm — it fails from years of moisture cycling into seams and edges that were never built to shed it.
HZ5 Climate Engineering
James Hardie manufactures regional product formulations, and the HZ5 line is engineered for climates like ours — the Pacific Northwest's wetter, cooler, more moisture-saturated conditions. The plank density, moisture resistance, and freeze-thaw performance are tuned for the kind of weather Whatcom County actually sees, rather than a national average. That regional engineering is a big part of why we don't treat Hardie as interchangeable with other fiber cement or composite products on the market — the formulation matters as much as the material category.
ColorPlus Factory Finish
Most of what we install uses Hardie's ColorPlus finish — a coating baked onto the plank at the factory under controlled conditions, rather than field-painted after installation. It resists fading, chipping, and cracking far better than a job-site paint job, and it comes with its own finish warranty separate from the substrate warranty. For homeowners, that means fewer repaint cycles over the life of the siding, which matters a lot in a climate where exterior paint takes a beating from UV, salt, and constant damp.
The Product Lines We Work With
James Hardie isn't one product — it's a system, and we spec different lines depending on the home and the exposure:
- HardiePlank lap siding — the workhorse for most homes, available in several profiles and textures
- HardiePanel vertical siding — often used for modern facades or as an accent alongside lap siding
- HardieShingle — for homes where a shingle or shake look fits the neighborhood character
- HardieTrim — matched trim boards so the whole envelope, not just the field siding, is fiber cement
The Warranty Actually Means Something
James Hardie backs its siding with a long transferable limited warranty, and the ColorPlus finish carries its own separate coverage. Transferability matters more than people expect — it protects resale value and gives the next owner real coverage, not just a marketing line. But a warranty is only as good as the installation underneath it, which is the other half of why we standardized on one product: we know this system cold. We know the correct nailing patterns, clearances off grade and roof lines, joint treatment, and caulking practices that James Hardie's own specifications call for, and we don't have to relearn a different set of installation rules for five different brands.
Why Installation Sensitivity Matters Here
Fiber cement is not a forgiving product if it's installed wrong — gaps, wrong fasteners, or missed flashing details can undermine even the best material. That's true of any siding, but it's especially true in a marine climate where wind-driven rain finds every shortcut. We treat correct installation as inseparable from the product decision. Installing one system exclusively means our crews aren't switching techniques from job to job, which reduces the chance of the kind of small errors that cause big problems five or ten years down the road.
Why We Don't Diversify
We're aware that limiting ourselves to one manufacturer means turning away some jobs and some budgets. We're fine with that trade. Fairhaven homes face enough real moisture exposure — from the bay, from the rain, from the moss that grows on anything that stays damp too long — that we'd rather install one product exceptionally well than several products adequately. That's the standard we've built the business around.
If you're planning a siding replacement or new build in Fairhaven or elsewhere in Whatcom County, we're happy to walk your home, talk through what James Hardie would look like on your specific exposure, and give you a straightforward, no-pressure estimate — no hard sell, just an honest look at what your house needs.
