Blaine Exterior Cedar Looks Beautiful on Day One. Let's Talk About Day Two Thousand.
Cedar siding has a real appeal, and we won't pretend otherwise. The grain, the warmth, the way it ages toward a silvery patina if you let it — it's a genuinely handsome material, and it's a traditional choice in Pacific Northwest building. If you're weighing cedar for a home in Blaine, you deserve a straight answer about what owning it actually involves, not just a sales pitch either for or against it.
We don't install cedar siding. Not because it's a bad product, but because what it demands from a homeowner over the decades doesn't match what most people actually want to spend their weekends doing — and Whatcom County's coastal climate makes those demands heavier than they'd be almost anywhere else in the state.
What Cedar Actually Requires
Cedar is a natural, organic material, and it behaves like one. Left unfinished or under-maintained, it absorbs moisture, and moisture is the thing that starts every problem this siding has. To keep cedar performing the way it's supposed to, a homeowner is generally looking at:
- Re-staining or re-sealing every 2 to 4 years, sooner on faces that take direct weather
- Regular inspection for checking, cupping, and splitting as boards move with humidity swings
- Caulking and re-caulking joints and trim as the wood expands and contracts
- Prompt repair or replacement of any board that starts to rot before it spreads to neighbors
- Active moss and mildew control on shaded or north-facing walls
None of that is exotic. It's just ongoing, and it's real labor or real money, year after year, for as long as you own the house.
Why Blaine's Climate Makes This Harder
Blaine sits right on Semiahmoo Bay, and that location cuts both ways for cedar. The salt-laden air off the water accelerates the breakdown of finishes and speeds corrosion on fasteners, so stain and sealer coats don't last as long here as they would inland. Add Whatcom County's driving winter rain, blown almost sideways off Georgia Strait during a lot of storms, and cedar's end grain and joints get more direct water exposure than a typical dry-side installation ever sees.
Then there's moss. Blaine's long, wet, mild winters give moss and algae months of ideal growing conditions on any wall that doesn't get much sun — and on a lot of lots around here, tree cover means that's most of the north and east elevations. Moss holds moisture against the wood surface, which is exactly what accelerates rot underneath a finish that looks fine from the driveway. Cedar sheds this kind of growth eventually, but usually only after it's already done some damage.
None of this means cedar "fails" in Blaine. Plenty of cedar-sided homes here have been kept up beautifully. It means the maintenance schedule that works fine somewhere drier gets compressed here — you're re-staining more often, catching rot earlier, and dealing with moss more aggressively than the same house would need two hundred miles inland.
The Real Trade-Off
Cedar's cost isn't really the sticker price of the siding — it's the recurring cost of staying ahead of moisture for the life of the house. Skip a maintenance cycle or two, which happens to almost every busy household at some point, and cedar doesn't just look tired. Trapped moisture behind a failing finish can lead to rot that requires actual board replacement, not just a fresh coat of stain.
That's the honest trade-off: cedar gives you a natural material with real curb appeal, in exchange for a maintenance commitment that doesn't let up, in a climate that's harder on wood than most.
Why We Install James Hardie Instead
This is why our company standardized on James Hardie fiber cement and doesn't install cedar, LP SmartSide, vinyl, or other fiber cement brands. Hardie board is engineered from cement, sand, and cellulose fibers — it doesn't absorb water the way wood does, it won't rot, and it's non-combustible, which matters given the wildfire smoke seasons the whole region has seen in recent summers.
Hardie's ColorPlus factory finish is baked on under controlled conditions, not brushed on in the field, and it's built to hold color far longer than a field-applied stain has to work against salt air and rain. The HZ5 product line used in this region is engineered specifically for wet, variable Pacific Northwest climates. You still get a real board profile with dimension and shadow lines — lap, shingle, or panel styles that read as a genuine siding material, not a plastic stand-in — but without the multi-year maintenance clock cedar puts on every wall.
We're not telling you cedar is worthless. We're telling you what two-plus decades of maintaining siding in this exact climate has taught us: for a material that has to survive Blaine's salt air, driving rain, and moss season with the least amount of homeowner upkeep, fiber cement is what we're willing to put our name on.
