Ferndale Siding One Product Line, On Purpose
Homeowners sometimes ask why our estimates only mention James Hardie fiber cement, never vinyl, LP SmartSide, Cemplank, Allura, or wood. It's a fair question. The short answer: after years of installing and repairing siding around Ferndale and the rest of Whatcom County, we standardized on one manufacturer because it consistently holds up to our specific weather, and we'd rather be excellent at one system than mediocre across five.
What Ferndale's Climate Actually Does to Siding
Ferndale sits close enough to Bellingham Bay and the Strait of Georgia that salt-laden air is part of daily life, not an occasional event. Add in driving rain off Puget Sound weather systems, long gray stretches where siding barely gets a chance to dry out, and a moss season that can run eight or nine months on shaded north walls, and you have a climate that's genuinely hard on exterior materials. Wood swells and checks. Vinyl gets brittle in cold snaps and can warp when afternoon sun reflects off certain window glass. Some fiber cement competitors are more sensitive to moisture at cut edges than others. James Hardie's HZ5 formulation was engineered specifically for wetter, harsher climate zones like ours, and that engineering is the whole reason we trust it.
Why We Don't Install the Alternatives
This isn't about badmouthing other manufacturers — it's about what we've seen perform, and not perform, on real homes in this county.
- Vinyl siding is affordable and low-maintenance in mild climates, but it's a petroleum-based product that expands and contracts with temperature swings, can crack in a hard freeze, and has a ceiling on how well it resists impact and UV fading over decades. It also melts under moderate heat sources, which some homeowners don't realize until it's too late.
- LP SmartSide is an engineered wood product with a real following, and it's reasonably priced. But it's still wood-based at its core, meaning cut edges and any breach in the factory coating are entry points for moisture. In a region with our rainfall totals, that installation sensitivity worries us enough that we don't put our name on it.
- Cemplank and Allura are also fiber cement, and on paper they compete with Hardie. In practice, we've found Hardie's manufacturing consistency, factory finish quality, and regional product engineering to be a notch above, and we'd rather install fewer products well than juggle multiple supply chains and warranty structures.
- Primed spruce and cedar look beautiful and have a long tradition in the Pacific Northwest, but real wood siding demands a maintenance schedule — recaulking, repainting, moss and mildew treatment — that most homeowners underestimate. In a moss-prone, damp climate like Ferndale's, wood siding is a standing commitment, not a one-time purchase.
Every one of these products has legitimate strengths. We're not claiming otherwise. Our position is simply that, for the way homes weather in Whatcom County, they carry trade-offs in moisture behavior, maintenance burden, or installation sensitivity that we're not willing to gamble a client's siding investment on.
What James Hardie Gets Right
James Hardie fiber cement is non-combustible, which matters more each fire season, and it doesn't warp, rot, or attract pests. The HZ5 product line is formulated for exactly our region's freeze-thaw cycles and moisture exposure. The ColorPlus factory finish is baked on under controlled conditions, so the color and coating adhesion is more consistent than field-applied paint, and it resists the fading and peeling that shows up on lesser coatings after a few Ferndale winters. Hardie also backs its products with a strong transferable limited warranty, which matters if you sell the home down the road.
Product Lines We Work With
- HardiePlank lap siding — the most common choice, available in smooth or cedar-textured finishes
- HardiePanel vertical siding — often used for accent walls or modern designs
- HardieShingle — for a shingle-style look without the maintenance of real wood shakes
- HardieTrim — matching trim boards for a finished, factory-consistent look
Installation Is the Other Half of the Equation
Fiber cement only performs as promised when it's installed to Hardie's published specifications — correct clearances above grade and roof lines, proper fastener placement, sealed cut edges, and flashing details that account for our rain patterns. A product with a great warranty can still fail prematurely if it's hung wrong. Standardizing on one system lets our crews install it the same correct way on every job, every time, rather than switching techniques between five different materials.
