Ferndale Siding Exterior Work Built for Custer's Climate
Custer sits in the rural stretch of Whatcom County between Ferndale and the Canadian border, close enough to Birch Bay and the Strait of Georgia that salt-laden air is a real part of life here, not just a coastal talking point. Combine that with Western Washington's long, wet winters and the mossy, shaded conditions that come with tree cover and fog, and you've got an exterior environment that punishes the wrong materials fast. Homes in Custer aren't dealing with a single hazard — they're dealing with the combination of moisture, salt, and organic growth working on the siding, trim, and roofline year-round.
We're a local crew that works this part of Whatcom County regularly, and Custer's exterior needs are pretty consistent from property to property: siding that won't wick moisture at the seams, roofing that sheds water without trapping it under moss, windows that seal tight against driving rain, and decks that can handle standing outside through a wet season without rotting underneath.
Why Salt Air and Driving Rain Matter Here
Salt air accelerates corrosion on fasteners, flashing, and any exposed metal, and it degrades certain coatings faster than inland conditions would. Driving rain — the kind that comes in sideways off a winter storm system — doesn't just hit a wall, it gets pushed into every gap, seam, and improperly lapped joint. On a lot of older homes in this area, that's exactly where problems start: water finds its way behind siding that was installed with the wrong overlap, caulked instead of properly flashed, or built from a material that swells and distorts once it's saturated.
Moss is the other piece. Long stretches of damp, shaded weather let moss and algae establish on roofs, north-facing siding, and anywhere airflow is limited. Beyond the cosmetic issue, moss holds moisture against the surface underneath it, which is a slow, steady problem for wood-based products and asphalt roofing alike.
Why We Only Install James Hardie Fiber Cement Siding
We made a decision a while back to standardize on James Hardie fiber cement and stop installing vinyl, LP SmartSide, primed spruce, cedar, and other fiber cement brands. That's not a marketing angle — it's a practical response to what we see failing on homes in exactly this kind of climate.
- Non-combustible material — fiber cement doesn't burn, which matters regardless of location and gives homeowners one less thing to worry about.
- Moisture behavior — Hardie's fiber cement composition holds up to sustained wet conditions far better than wood-based composite or engineered wood products, which can swell, delaminate, or take on moisture at cut edges if they aren't sealed and maintained precisely.
- ColorPlus factory finish — a baked-on finish that resists fading and holds color consistency better than field-applied paint, which matters when a home is exposed to sun, salt, and rain in the same season.
- Climate-engineered HZ product lines — Hardie makes versions of its siding engineered for specific climate zones, including the wetter conditions common to the Pacific Northwest.
- Warranty structure — a strong, transferable warranty backs the product when it's installed to manufacturer spec, which gives homeowners real protection instead of a policy full of exclusions.
Vinyl and engineered wood products aren't inherently bad materials — they work fine in some climates and budgets. But in a place where wind-driven rain and salt air are a given and moss season lasts a good chunk of the year, we'd rather install one product we trust completely than several we'd have to caveat. That's the whole reason we narrowed our lineup instead of offering "options."
Roofing, Windows, and Decks — Same Standard
Siding doesn't work in isolation. A roof that's shedding moss and holding moisture undermines the wall assembly below it. Windows that aren't properly flashed become the exact gap that driving rain exploits. Decks exposed to standing water and shade are prone to the same rot issues as poorly protected siding. We handle all four — siding, roofing, windows, and decks — because on a Custer property, they're one connected system, and treating them that way is how you actually stop water problems instead of chasing them room by room.
What a Local Crew Adds
Working this area consistently means we're not guessing at what Custer homes are up against. We know what a season of driving rain does to an improperly lapped seam, what a shaded north wall looks like after a few years of moss, and what fastener corrosion looks like on a place close enough to the water to catch salt air. That's the kind of judgment that shows up in the small installation details — flashing choices, fastener spacing, ventilation — that separate siding that lasts decades from siding that needs attention in five years.
