Custer One Product, No Exceptions
Homeowners in Custer sometimes ask why we don't offer a menu of siding brands like some contractors do. The answer is simple: we install James Hardie fiber cement siding, and that's it. Not because we haven't looked at the alternatives — we have, closely — but because after years of siding homes along Washington's northern coastline, we settled on the one product we're confident will hold up to what Whatcom County weather actually does to a house.
What This Climate Does to Siding
Custer sits close enough to the Strait of Georgia and Semiahmoo Bay that salt-laden air is a daily fact of life, not an occasional event. Add in the driving rain that blows sideways off the water, a moss and mildew season that can stretch from October through May, and the freeze-thaw cycles that hit us a few times most winters, and you've got a punishing combination for exterior materials. Wood siding wants to absorb moisture and swell. Vinyl wants to get brittle in cold snaps and warp in direct sun. Some fiber cement competitors cut corners on the cement formulation itself. Fiber cement done right — meaning James Hardie's engineering, backed by their HZ5 climate-specific product line — is built to shrug off exactly these conditions.
What James Hardie Actually Is
James Hardie siding is fiber cement: a mix of cement, sand, and cellulose fibers, cured and formed into planks, panels, and shingle-style products. It's non-combustible, which matters more every year as wildfire smoke and ember risk become a regional concern even here in the northwest corner of the state. It doesn't feed on moisture the way wood does, and it doesn't expand and contract with temperature swings the way vinyl does. Properly installed, it holds paint and color far longer than wood siding typically does, and it doesn't rot, delaminate, or attract the kind of pest damage cedar can be prone to over time.
The HZ5 Climate Engineering
James Hardie makes region-specific formulations under its HZ system. HZ5 is engineered for the Pacific Northwest's wet, moderate climate — different moisture and freeze-thaw performance than the formulations sold in Arizona or Florida. That regional engineering is part of why we standardized on Hardie specifically for Whatcom County homes rather than a generic fiber cement product.
ColorPlus: Factory Finish, Not Field Paint
Most of what we install uses Hardie's ColorPlus finish — a color baked on at the factory under controlled conditions, rather than field-applied paint that has to cure on-site in whatever weather shows up that week. ColorPlus finishes carry their own finish warranty separate from the substrate warranty, and the color consistency and adhesion are simply better than what a painter can achieve on a rainy Custer job site. It also means less repainting over the life of the siding, which matters when you're weighing long-term cost, not just install-day cost.
Product Lines We Work With
- HardiePlank lap siding — the most common choice, available in several exposures and styles including smooth and cedar-textured finishes
- HardieShingle — for homes wanting a shingle or shake look without the maintenance wood shingles require
- HardiePanel — vertical panel siding, often used for accents, gables, or a more modern look
- HardieTrim — matching trim boards for a consistent, factory-finished system top to bottom
The Warranty Question
James Hardie backs its siding with a strong transferable limited warranty on the substrate, and ColorPlus finishes carry their own separate finish warranty. Transferability matters to resale-minded homeowners — if you sell your Custer home within the warranty period, that coverage generally follows the house, not just the original owner. That's a meaningful difference from products where warranty coverage is thinner or harder to transfer.
Why Installation Matters as Much as the Product
Fiber cement is only as good as the install. Hardie is specific about fastener patterns, clearances off grade and roof lines, caulking practices, and flashing details — and skipping those steps is where problems start, regardless of brand. We install strictly to Hardie's published specifications because that's what keeps the warranty valid and what actually gives you the performance the product is engineered for. A big part of why we refuse to install other products is that we'd rather be excellent at one system than mediocre across several.
What This Means for Your Project
Choosing to install only James Hardie means we turn away some jobs where a homeowner has their heart set on vinyl or cedar. We're upfront about that. But it also means every crew member on your Custer project knows this product cold — the fastening specs, the caulking points, the trim details — because it's the only system we work with. For a house that has to stand up to Whatcom County's salt air, rain, and moss season year after year, we think that specialization is worth more than variety.
If you're considering a siding replacement or new construction project in Custer or elsewhere in Whatcom County, we're happy to walk your property, look at your exposure to weather and salt air, and talk through which Hardie product line makes sense.
