Ferndale Siding in Lynden, Washington
Lynden sits inland from Ferndale but shares the same weather system that moves in off the Salish Sea — long stretches of driving rain, damp air that doesn't fully clear for months at a time, and enough moisture in the ground and the atmosphere to keep moss and algae established on anything that holds shade. Add in the salt-laden air that carries inland from the coast on a west wind, and you've got a set of conditions that are hard on exterior building materials, especially anything that relies on paint film or a factory coating that isn't built for this specific climate.
We're a siding, roofing, window, and deck contractor based in Ferndale, and Lynden is part of our regular service area. That matters more than it sounds like it should. A crew that works this corner of Whatcom County every week knows what a north-facing wall looks like after ten wet winters, knows which details tend to trap moisture behind trim, and knows the difference between cosmetic moss growth and the kind that's sitting on top of a moisture problem that's already started underneath.
What Lynden homes are up against
- Driving rain — wind-driven rain doesn't just fall on siding, it gets pushed sideways into laps, seams, and trim joints. Poorly sealed or poorly installed siding lets that water behind the cladding, where it doesn't dry out quickly.
- Extended damp seasons — long stretches without real drying weather mean any moisture that gets trapped stays trapped longer here than it would in a drier climate.
- Moss and algae — shaded walls, roof valleys, and north-side siding stay damp long enough for organic growth to take hold, which then holds even more moisture against the surface.
- Salt air — even well inland, coastal air movement carries enough salt to accelerate corrosion on fasteners and wear on lesser coatings over time.
None of this is unusual for the area — it's just the reality of building and maintaining a home in this part of Washington. The point isn't to alarm anyone, it's to build and repair things with that reality in mind instead of ignoring it.
Why we install James Hardie fiber cement, and nothing else
We made a deliberate decision to standardize on James Hardie fiber cement siding and stop installing vinyl, LP SmartSide, cedar, primed spruce, or other fiber cement brands. That wasn't a marketing decision — it came out of watching how different products actually hold up over years in this exact climate.
Fiber cement is non-combustible and dimensionally stable, so it doesn't expand and contract the way wood-based or vinyl products do when they cycle through wet and dry conditions. James Hardie's ColorPlus finish is factory-applied and baked on under controlled conditions, which gives it better resistance to fading and moisture intrusion than field-applied paint. Hardie also engineers regional product lines (their HZ5 line, for example) specifically for climates like ours, with moisture and impact performance tuned for the Pacific Northwest rather than a generic national spec.
We're not going to tell you that other products fall apart — plenty of homes around here have vinyl or wood siding on them and get by fine with regular maintenance. What we will say is that after years of installation and repair work in Whatcom County, we stopped being willing to put our name behind products that ask homeowners to stay ahead of paint failure, moss cleaning, and moisture callbacks in a climate that makes all three harder than they need to be. Hardie, installed correctly, takes a lot of that maintenance burden off the table and backs it with a strong transferable warranty.
How we approach a Lynden project
Correct installation matters more than the product itself. Flashing details around windows and doors, proper clearances at grade and roof lines, and correct fastening are what actually keep water out — not just the siding material. We install to manufacturer spec, which is what makes the warranty coverage meaningful rather than theoretical.
Beyond siding, we handle roofing, window replacement, and decks, and we look at those systems together rather than in isolation. A roof that's shedding water onto a wall, a window that's not flashed correctly, or a deck ledger board tying into siding the wrong way can undo good work elsewhere on the house. A local crew that sees these interactions regularly catches them before they become a bigger repair.
What to expect
| Concern | What we do |
|---|---|
| Wind-driven rain intrusion | Correct flashing and lap details, sealed per manufacturer spec |
| Moss and algae buildup | Factory-finished cladding that resists organic growth better than bare or painted wood |
| Salt air corrosion | Corrosion-resistant fastening and trim details suited to coastal-influenced air |
| Long-term maintenance | ColorPlus factory finish reduces repainting cycles compared to field-painted siding |
