Bellingham Siding Why We Standardized on One Siding Brand
We get asked fairly often why we don't offer a menu of siding options the way some contractors do. The honest answer is that after years of tearing old siding off Bellingham homes and seeing what actually holds up under Whatcom County weather, we stopped installing anything but James Hardie fiber cement. This page explains what that product is, why it fits our climate, and what you're actually paying for.
What James Hardie Siding Actually Is
James Hardie makes fiber cement siding — a blend of cellulose fiber, sand, and Portland cement that's cured into dense, dimensionally stable boards and panels. It's not plastic (like vinyl), and it's not an engineered wood product (like LP SmartSide). Because the core material has no wood fiber to swell, rot, or feed fungus, it behaves very differently in a wet coastal climate than the products it competes against.
That matters here specifically. Bellingham sits right on the water, which means siding on a lot of homes deals with salt-laden air, wind-driven rain coming sideways off Bellingham Bay, and long stretches — often five or six months — where moss and algae have the moisture and shade they need to take hold on a north-facing wall. Fiber cement doesn't give moss the organic material to grip and feed on the way wood-based sidings can, and it doesn't absorb water into its core the way wood fiber does.
The Product Lines We Install
James Hardie isn't one product — it's a system, and part of doing this job right is matching the right line to the right home and exposure.
- HardiePlank lap siding — the standard horizontal siding for most Bellingham homes, available in several textures (cedarmill, smooth, beaded) and widths.
- HardiePanel vertical siding — used for board-and-batten looks and modern facades.
- HardieShingle — a straight-edge or staggered shingle profile for homes wanting a shingle-style look without the maintenance of real cedar shingles.
- HardieTrim — matching trim boards for a consistent, factory-finished look at corners, fascia, and window/door surrounds.
Hardie also engineers products by climate zone under its HZ5 designation, which covers our region's freeze-thaw cycles and moisture exposure. It's a small distinction on paper but it means the product spec'd for a Bellingham home is built for Bellingham conditions, not a generic national spec.
ColorPlus: The Finish Is Part of the Engineering
A lot of homeowners assume the paint is the same regardless of who installs it. It isn't. Hardie's ColorPlus finish is baked on in a factory-controlled process — multiple coats, cured, before the boards ever reach a job site. That's a very different process than a field-painted product, where the finish quality depends on weather conditions the day it's sprayed and how many coats actually go on. Factory finishing gives more consistent coverage, better fade resistance, and touch-up paint that's color-matched to the batch. In a climate where siding stays damp for long stretches and gets a lot of indirect UV rather than a hard, dry bake, a consistent factory finish holds up more predictably than field-applied paint.
Non-Combustible Is Not a Marketing Line
Fiber cement doesn't burn. That's not a performance claim we're spinning — it's a basic property of the material's composition. For homeowners in Whatcom County thinking about wildfire exposure, insurance considerations, or simply wanting one less combustible material on the exterior of their home, that's a real, tangible difference from wood-based or foam-backed siding products.
What the Warranty Actually Covers
James Hardie backs its siding with a non-prorated limited warranty and the ColorPlus finish carries its own separate finish warranty. Warranties are transferable to a subsequent homeowner within a set window, which matters if you're thinking about resale. We won't quote you exact terms here because warranty language changes and you should read the current documentation for your specific product — but the structure is worth understanding before you compare it to warranties on other siding products, which are often prorated or shorter.
Why Correct Installation Matters as Much as the Product
Fiber cement is a forgiving material chemically, but it's not forgiving of sloppy installation. Manufacturer specs on fastener placement, clearance from grade and roof lines, flashing at penetrations, and caulking at joints all exist for a reason — skip them and you can still get moisture problems behind the best siding on the market. Part of why we only install one product is that it lets our crews get genuinely good at one installation spec rather than juggling five different manufacturers' requirements. In a market with our rainfall and humidity, that installation discipline is where a lot of long-term performance actually comes from — the material gets you most of the way there, correct flashing and fastening finish the job.
Is Hardie Right for Every Home?
It's a heavier, more rigid material than vinyl, which means it needs proper structural fastening and isn't a same-day DIY swap. It also costs more upfront than vinyl or engineered wood siding. For homeowners planning to stay in their Bellingham home for the long haul, or anyone tired of repainting or patching moisture-damaged siding every few years, the trade-off has consistently made sense in our experience — but we'd rather explain the honest comparison than oversell it.
