Blaine Siding One Product, By Design
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 install a wider range of products, and over years of work on homes here in Blaine and around Whatcom County, we narrowed it down to one — James Hardie fiber cement. Not because it's the cheapest option or the easiest to install, but because it's the one product we can stand behind fully, on every home, in this specific climate.
This page explains the reasoning, not just the marketing.
What Our Climate Actually Does to Siding
Blaine sits right on the water, at the edge of Semiahmoo Bay and Boundary Bay, which means salt-laden air is a daily fact of life here, not an occasional event. Combine that with Whatcom County's long wet season — driving rain off the Strait of Georgia, months of low sun angle, and a moss and mildew season that can run from October through May — and you have an environment that's genuinely hard on exterior materials.
Wood-based products swell, absorb moisture at cut edges, and need repainting on a schedule. Vinyl can warp or fade under UV and doesn't hold caulking joints well when it expands and contracts through our temperature swings. None of these are dramatic failures — they're slow, cumulative maintenance burdens that show up five, ten, fifteen years down the road, usually right when a homeowner assumed the siding was a "done" item.
Why Fiber Cement Behaves Differently
James Hardie siding is made from cement, sand, and cellulose fiber. It doesn't absorb bulk water the way wood-based sidings do, it won't rot, and it's non-combustible — a genuinely relevant fact given wildfire smoke seasons that now affect Western Washington too. It expands and contracts far less than wood or vinyl with temperature and humidity changes, which matters a lot when you're dealing with joints, caulking, and paint film over a 30- or 40-year timeframe.
Engineered for This Specific Region
James Hardie makes climate-specific product formulations, and the HZ5 line is engineered for regions like ours that see more moisture and moderate freeze conditions rather than deep cold. That's not a marketing distinction we take lightly — it's the actual reason we spec HZ5 products for jobs in Blaine rather than a generic national formulation.
ColorPlus: Why the Finish Matters as Much as the Board
A lot of the long-term maintenance problems people associate with siding actually come from the paint, not the substrate. James Hardie's ColorPlus finish is baked on at the factory under controlled conditions, with multiple coats and a UV-cured topcoat — a process that's simply not replicable with a job-site paint sprayer. In a place with our rain patterns and moss growth, a factory finish that resists fading and holds up to mildew washing is not a cosmetic upgrade, it's a functional one.
We do install primed Hardie board in cases where a custom color is specifically wanted, but we always walk homeowners through the trade-off: field-applied paint will need attention on a shorter cycle than ColorPlus.
The Product Lines We Work With
- HardiePlank lap siding — the most common choice, available in several exposure widths and textures (smooth or cedarmill)
- HardiePanel — vertical panel siding, often used for accents, gables, or a modern look
- HardieShingle — staggered or straight-edge shingle profiles for a traditional look without cedar's maintenance
- HardieTrim — matching trim boards for corners, fascia, and window/door surrounds
Installation Is Where It's Won or Lost
Fiber cement is not a forgiving product if it's installed wrong. Correct fastener spacing, proper clearance from grade and roof lines, correctly flashed and sealed joints, and manufacturer-spec house wrap all matter — especially in a climate that drives rain sideways off the water for weeks at a time. We install strictly to James Hardie's published specifications, because a product this good is only as good as the installation behind it, and we're not interested in cutting corners on the one system we've chosen to build our reputation on.
The Warranty Behind It
James Hardie backs its siding with a strong transferable limited warranty, and ColorPlus finishes carry their own separate finish warranty. That transferability matters to resale value in a market like Blaine's, where buyers increasingly ask direct questions about exterior condition and maintenance history.
Where This Leaves Homeowners
We're not going to tell you every other siding product is a bad product — plenty of them have legitimate uses and loyal installers. What we will tell you is that after years of real-world exposure to this coastal, wet, moss-prone corner of Washington, James Hardie is the one system we're willing to install without reservations, warranty, and maintain our name behind.
If you're weighing siding options for a home in Blaine or elsewhere in Whatcom County, we're happy to walk your property, look at your specific exposure and conditions, and give you a straightforward, no-pressure estimate on a James Hardie system built for this climate.
