Ferndale Siding Siding Built for Lynden's Weather, Not Just Its Look
Lynden sits within the stretch of Whatcom County we work in every week, and the houses out here take a specific kind of beating. It's not one dramatic storm that wears down a home's exterior — it's the accumulation of a long, wet Pacific Northwest year: months of low-intensity rain, stretches of damp air that never fully dries out, wind-driven moisture that finds its way into every gap and seam, and a moss season that seems to start earlier and last longer with each passing year. Add in the salt-tinged air that moves inland off the Sound and up through the county, and you've got a climate that's genuinely hard on exterior building materials, even when a home looks fine from the curb.
We install siding, roofing, windows, and decks for homeowners throughout this part of Whatcom County, and the pattern we see on older homes is consistent: cracked or delaminating panels, soft trim boards, moss creeping up from the roofline and eaves, and paint that needs recoating far more often than anyone expected when the siding went on. None of that is a surprise once you understand what the local climate is actually doing to a wall system day after day, year after year.
What Driving Rain and Constant Moisture Do to a House
The biggest threat to a home's exterior here isn't a single hard rain — it's persistent, wind-driven moisture that gets pushed sideways into siding joints, around window and door trim, and along the bottom edges of panels. Over time, materials that absorb water or swell when wet start to fail from the inside out, often well before any damage is visible on the surface. Materials that resist water absorption altogether hold up dramatically better, which is a big part of why we've standardized on one product for every siding job we take on.
Moss, Shade, and the Long Damp Season
Whatcom County's tree cover and long overcast stretches mean a lot of homes sit in shaded, slow-to-dry conditions for much of the year. That's exactly the environment moss and algae favor. Once organic growth takes hold on siding, it holds moisture against the surface longer, which accelerates whatever damage is already happening underneath. Siding that can't stand up to sustained dampness is fighting an uphill battle in a climate like this one.
Why We Only Install James Hardie Fiber Cement
We made a deliberate decision years ago to stop installing vinyl, LP SmartSide, Cemplank, Allura, and primed wood species like spruce or cedar — not because those products have no merit, but because none of them hold up as consistently in this specific climate as James Hardie fiber cement does. Here's the honest breakdown of why:
- Non-combustible material. Fiber cement doesn't burn, warp, or melt the way vinyl and some engineered wood products can under heat exposure — a meaningful difference for long-term peace of mind.
- Engineered for wet climates. Hardie's HZ10 product line is specifically formulated for the Pacific Northwest's moisture and freeze-thaw cycles, unlike general-purpose siding lines designed for drier regions.
- Moisture resistance that lasts. Fiber cement doesn't absorb and swell the way wood-based products can, and it doesn't experience the moisture-related warping issues that have affected some engineered wood siding products in wet regions.
- Factory-applied ColorPlus finish. The baked-on finish resists fading and holds up to UV and moisture exposure far longer than field-applied paint, meaning fewer repaint cycles over the life of the siding.
- A strong, transferable warranty backed by a manufacturer with decades of a track record in siding specifically formulated for regions like ours.
Vinyl siding is inexpensive and low-maintenance in some climates, but it can become brittle in cold snaps and doesn't offer the same fire performance or premium appearance as fiber cement. LP SmartSide, Cemplank, and Allura are legitimate products with their own strengths, but in our experience installing exteriors throughout this county, none of them match Hardie's combination of moisture engineering, finish durability, and warranty support for what this climate demands. Primed cedar and spruce require the most diligent, ongoing maintenance of all — regular recoating and moisture monitoring — which is a real commitment most homeowners underestimate when they choose it for its natural look.
What Working with a Local Crew Actually Means
A crew that works Whatcom County regularly knows how local moisture, wind exposure, and moss growth actually behave against a wall — not in general terms, but on the specific kinds of homes and lots common to this area. That shows up in the details: how flashing and trim are detailed around windows and doors, how siding is held clear of grade and hard surfaces, and how ventilation is handled behind the cladding so moisture has somewhere to go instead of getting trapped.
Beyond siding, we handle roofing, window replacement, and decks — which matters because these systems all interact. A roof that's shedding water properly, gutters that are directing it away from walls, and siding that's correctly flashed at every transition work together as one weather envelope. Get one piece wrong and the others take on more punishment than they were built for.
| Local Condition | What It Does to Exteriors |
|---|---|
| Wind-driven rain | Pushes moisture into seams, joints, and trim intersections |
| Extended shade and damp air | Feeds moss and algae growth, slows drying time |
| Salt-influenced coastal air | Accelerates corrosion and finish breakdown on lower-grade materials |
| Freeze-thaw cycling | Stresses materials prone to swelling or cracking under moisture |
