Ferndale Cedar Looks Beautiful. That's Never Been the Question.
Nobody argues with cedar siding on looks. The grain, the warmth, the way it ages toward silver if you let it — it's a genuinely handsome material, and it's been used on Pacific Northwest homes for generations. If a homeowner in Ferndale asks us about cedar, we don't tell them it's a bad-looking product, because it isn't. What we tell them is what it actually takes to keep that look, or keep the wood itself intact, once it's on a house that sits a few miles from Bellingham Bay and gets hit by driving rain most of the year.
What Cedar Is Actually Up Against Here
Whatcom County isn't a gentle climate for exterior wood. We get long stretches of wet weather, salt-laden air coming off the water, and a moss season that can run from fall through spring. Cedar is naturally rot-resistant compared to other softwoods, but "rot-resistant" is a relative term — it still absorbs moisture, still moves with humidity, and still needs a dry break between soakings to perform the way it's supposed to. In a lot of years, Ferndale doesn't give it one.
- Constant moisture exposure: Driving rain off the Strait doesn't just fall straight down — it drives sideways into walls, soaking into end grain, seams, and butt joints where boards meet.
- Salt air: Airborne salt accelerates the breakdown of finishes and can draw moisture into wood fibers even on days it isn't actively raining.
- Moss and algae: Shaded, north-facing, or tree-covered walls stay damp long enough for moss and mildew to take hold, and once it's established on cedar, it's a recurring fight, not a one-time cleaning.
The Maintenance Cedar Actually Requires
This is the part that doesn't always make it into the sales pitch. Cedar siding is a maintained product, not a set-it-and-forget-it one. To get a normal service life out of it, a homeowner is signing up for an ongoing routine, not a one-time installation.
| Task | Typical Frequency |
|---|---|
| Re-stain or re-seal exposed faces | Every 3-5 years, sooner on sun/rain-exposed walls |
| Wash to remove moss, algae, and mildew | Annually, more often on shaded elevations |
| Inspect and re-caulk joints and trim | Annually |
| Spot-replace split, cupped, or rotted boards | As needed, ongoing over the home's life |
Skip that schedule for a few years — which is easy to do, since most homeowners aren't thinking about their siding until something looks wrong — and cedar starts showing it: graying and splitting where the finish has failed, cupped or warped boards from repeated wet-dry cycling, and soft spots where moisture has worked its way in around fasteners or end cuts. None of that means the wood was bad. It means the maintenance window closed and the climate did what it does.
Where Cedar Also Struggles: Fire and Pests
Two more honest points worth naming. Cedar is combustible — it's wood, and in a wildfire-adjacent or ember-exposure scenario that matters, where a non-combustible cladding doesn't carry the same risk. And untreated or under-maintained cedar is attractive to carpenter ants and other wood-boring insects, particularly once moisture has softened the fibers. Neither of these is a defect in the product. They're just physical realities of building an exterior wall out of solid wood in a wet coastal county.
Why We Standardized on James Hardie Instead
We don't install cedar siding, and it isn't because we think it's a poor product — it's because we've made a professional call that our customers are better served by a cladding that doesn't ask this much of them year after year. James Hardie fiber cement is engineered specifically to hold up in wet, moss-prone, coastal-influenced climates like ours. It's non-combustible, it doesn't rot or feed insects, and it comes from the factory with a ColorPlus finish baked on — no re-staining schedule, no annual sealing, no five-year clock running in the background.
Hardie's HZ5 product line is built for exactly the moisture and weathering profile a Ferndale or broader Whatcom County home deals with, and it's backed by a strong transferable warranty when installed to spec — which matters, because fiber cement performance depends heavily on correct installation: proper flashing, clearances, and fastening. That's the install discipline we bring to every job, and it's a big part of why we stopped installing wood siding in the first place.
