Ferndale Siding Exterior Work in the Blaine Area
Blaine sits close enough to the water that homes there deal with a different mix of weather than you'll find further inland in Whatcom County. Salt air off the strait, driving rain that comes in sideways during winter storms, and a long stretch of the year when moisture just sits on north-facing walls and rooflines — it's a combination that wears down exterior materials faster than most homeowners expect. If you've lived in or near Blaine for more than a few years, you've probably already seen it: paint failing early, trim softening at the corners, or a green haze creeping across siding and shingles that never seems to fully dry out.
Ferndale Siding Contractors works this part of Whatcom County regularly, and we bring a Blaine job the same standards we'd bring to any home in our service area — correct flashing and water management details, materials chosen for how they actually perform in this climate, and a crew that shows up and finishes what they started.
What Blaine's Climate Does to a House
A few things stand out when we're evaluating a home's exterior in this area:
- Salt air corrosion. Proximity to the water means airborne salt settles on fasteners, flashing, and any exposed metal. Over time this accelerates corrosion in ways that inland homes just don't deal with as much.
- Wind-driven rain. Winter storms in this area don't just drop rain straight down — wind pushes it sideways into wall assemblies, seams, and anywhere flashing or caulking has started to fail. Materials and details that work fine in calm rain can still let water in during a real Blaine storm.
- Moss and algae growth. Long stretches of damp, shaded weather — especially on north- and west-facing walls, under eaves, and near trees — create ideal conditions for moss and mildew to take hold on siding, trim, and roofing.
- Slow drying cycles. When a house doesn't get consistent direct sun and airflow, moisture that gets into a wall or sits on a surface takes longer to evaporate, which extends the window for rot and material breakdown.
Why We Only Install James Hardie Siding
We made a decision as a company to install James Hardie fiber cement siding exclusively — not vinyl, not LP SmartSide, not cedar, not primed spruce. In a climate like Blaine's, that decision isn't about brand preference; it's about what actually holds up.
Fiber cement doesn't absorb and swell the way wood-based products can when they're exposed to repeated wetting from wind-driven rain. It's also non-combustible, which matters more every year as wildfire smoke and dry-season risk become a bigger part of Pacific Northwest summers, even in a generally wet county like Whatcom. James Hardie's HZ5 product line in particular is engineered for climates that see a lot of moisture cycling, and the factory-applied ColorPlus finish holds color and resists the kind of fading and chalking that repeated damp weather causes on field-painted materials.
None of this means other siding materials are worthless — vinyl and engineered wood products have their place and their price points. But we've seen enough coastal Whatcom County homes to know which products need the least babying five, ten, and twenty years down the road, and that's the direction we point every homeowner we work with.
Full Exterior Services, Not Just Siding
Most homes near Blaine that need siding work end up needing a look at more than just the walls. We handle:
- Siding replacement and repair — James Hardie fiber cement, installed to manufacturer spec with proper flashing and clearances
- Roofing — repair and replacement, with attention to how roof-to-wall transitions are flashed, since that's a common failure point in wind-driven rain
- Windows — replacement units and correct flashing integration with the surrounding siding, which matters more here than in drier climates
- Decks — built and repaired to handle year-round exposure to moisture without becoming a maintenance headache
Looking at the whole exterior together matters in this climate. A new roof with poor flashing detail at the wall line, or new siding installed around old, deteriorating window flashing, just moves the water problem somewhere else. We try to catch those connections rather than treating each component as a separate job.
Why a Local Crew Matters
Water management details that work in a drier part of the state don't always hold up on a home exposed to salt air and sideways rain. A crew that works Whatcom County regularly knows which details need extra attention here — how much lap and clearance to leave, where moss tends to build up and why that matters for long-term siding performance, and which walls on a typical Blaine home take the worst of the weather. That local, repeated experience is part of what keeps a project from becoming a callback.
We also don't cut corners to hit a lower bid. Correct installation — proper fastening, flashing, and sealing — is what makes any siding material perform the way it's supposed to, and it's non-negotiable on every job we take on.
