Ferndale Siding Siding Built for Blaine's Coastline
Blaine sits right on Semiahmoo Bay and Drayton Harbor, about as close to the water as a Whatcom County town gets. That location gives homeowners some of the best views in the county, but it also means their siding takes a beating that inland neighborhoods never see. Salt-laden air off the bay, wind-driven rain rolling in off the Strait, and a moss season that can stretch nine months out of the year all work together against whatever's on the outside of your house. We've been serving homes throughout Ferndale and the surrounding Whatcom County coastline, and Blaine is one of the areas where material choice matters most.
What the Climate Does to Siding Here
Salt air is corrosive to metal fasteners, trim, and coatings, and it accelerates the breakdown of anything not engineered to handle it. Combine that with rain that doesn't just fall straight down but gets driven sideways into wall assemblies during winter storms, and you have a recipe for moisture finding its way behind or into siding that isn't properly sealed and installed. Add Whatcom County's long, damp, low-sun winters — ideal moss and algae conditions — and any siding product with wood content or an absorbent surface is going to show it: staining, soft spots, and the slow rot that follows repeated wetting and drying cycles.
Homes on or near the water in Blaine tend to face this earlier and more aggressively than homes further inland in Ferndale. That's not a reason to panic, but it is a reason to be honest about what different siding materials can actually hold up to over the decades you'll own the house.
Why We Only Install James Hardie
We made the decision to install James Hardie fiber cement siding exclusively, and we don't install vinyl, LP SmartSide, Cemplank, Allura, or bare cedar and primed spruce. That's not a marketing angle — it's a standard we hold because of what we see on coastal Whatcom County homes over time.
- Non-combustible core: Hardie's fiber cement doesn't feed a fire the way wood-based products can, which matters for insurance and long-term peace of mind.
- Moisture resistance: Fiber cement doesn't absorb and swell the way wood-based siding does, which is exactly the failure mode salt air and driving rain expose fastest.
- ColorPlus factory finish: The baked-on finish resists fading and holds up to UV and moisture far better than field-applied paint, which means fewer repaint cycles on a house that's already dealing with harsh coastal exposure.
- HZ5 product engineering: Hardie makes climate-specific formulations, and the products rated for our wet Pacific Northwest conditions are built with that moisture load in mind — not a generic siding meant for a dry climate.
- Warranty backing: A strong, transferable manufacturer warranty gives homeowners real protection, not just a sales pitch, especially valuable if you ever sell a home in a desirable spot like Blaine.
Every one of those points connects directly back to what Blaine's environment throws at a house. We'd rather install one product correctly and stand behind it than offer a menu of options we know will underperform in this specific climate.
Installation Matters as Much as the Material
Fiber cement siding is only as good as the install behind it. Proper flashing at windows and doors, correct fastener placement, adequate clearance from grade and roof lines, and attention to the water-resistive barrier underneath all determine whether a house stays dry through a Whatcom County winter. On a coastal property like the ones in Blaine, we pay extra attention to these details because there's less margin for error when wind-driven rain is a regular event rather than an occasional one.
More Than Siding
Siding is what we're known for, but it's not the only thing protecting a Blaine home from this climate. We also handle roofing, windows, and decks — and all four systems interact. A roof that's shedding water properly, windows that are flashed and sealed correctly, and a deck built to handle repeated wet-dry cycles all work alongside good siding to keep moisture out of the structure. When we're on site, we're looking at the whole envelope, not just one component.
A Local Crew That Knows This Coastline
Being based in Ferndale means we're familiar with the differences between a sheltered inland lot and an exposed waterfront property like many in Blaine. We know which sides of a house typically take the worst weather, where moss tends to establish first, and what details get skipped by crews who aren't used to building for this environment. That local knowledge shows up in the small decisions — flashing details, ventilation, fastener choice — that determine whether siding lasts fifteen years or fifty.
