Cedar Siding: What It Gets Right
Cedar has a long history on homes in Whatcom County, and it's easy to see why. It's a genuinely beautiful material — real wood grain, warm color, and a natural look that no manufactured product perfectly replicates. It's also a renewable resource, it takes stain or paint well, and a freshly finished cedar home looks fantastic. We're not going to pretend otherwise. If we didn't respect cedar as a material, this page wouldn't need to exist.
The problem isn't how cedar looks on day one. It's what it takes to keep it looking that way for the next twenty or thirty years, in this specific climate.

Why Ferndale's Climate Is Hard on Wood Siding
Ferndale sits close enough to Bellingham Bay and the Salish Sea that salt-laden air is a real factor on siding, fasteners, and finishes — it accelerates weathering and corrodes exposed metal faster than it would further inland. Layer on Whatcom County's driving rain, which doesn't just fall straight down but gets pushed sideways into siding, trim, and joints during winter storms, and you've got a lot of moisture looking for a way into a wood product.
Then there's moss season, which around here isn't really a season — it's most of the year. Shaded walls, north-facing elevations, and anything near overhanging trees stay damp long enough for moss, algae, and mildew to take hold on wood surfaces. Cedar can handle occasional moisture. What wears it down is the combination Ferndale actually delivers: salt air, near-constant dampness, and long stretches without enough sun and wind to fully dry the wall between rain events.
The Real Maintenance Picture
Cedar siding is not a "install it and forget it" product, and any honest contractor will tell you the same. To get a normal service life out of it, a homeowner is signing up for an ongoing maintenance relationship with their siding:
- Refinishing every 3-5 years. Stain and sealant break down under UV and moisture exposure. Skip a cycle in this climate and the wood starts absorbing water it shouldn't.
- Moss and mildew treatment. Shaded and north-facing walls need regular cleaning to keep growth from holding moisture against the wood surface.
- Caulking and joint inspection. End grain and butt joints are where driving rain finds its way in first, and sealant has to be checked and redone periodically.
- Watching for cupping, warping, and checking. Wood moves with moisture cycles, and repeated wet-dry swings over years cause boards to distort or crack.
- Fastener corrosion checks. Salt air speeds up corrosion on nails and staples, which can stain the finish and eventually compromise how well boards stay fastened.
None of this makes cedar a bad material. It means cedar's real cost isn't just the install price — it's the recurring cost of upkeep, stretched out over decades, in a climate that doesn't give the wood much of a break.
Why We Standardized on James Hardie Instead
We made a business decision a while back to install only James Hardie fiber cement siding, on every job, in every corner of Whatcom County. That decision came directly out of watching how wood siding performs here over the long run versus how fiber cement does.
Hardie's HZ5 product line is engineered specifically for climates like ours — freeze-thaw cycles, sustained moisture, and coastal exposure. It's non-combustible, which matters for insurance and peace of mind, and it doesn't feed moss and mildew the way wood surfaces can. The factory-applied ColorPlus finish is baked on under controlled conditions and backed by its own finish warranty, which means no five-year repainting treadmill — homeowners are looking at a much longer stretch before the exterior needs attention again.
It's also dimensionally stable. Fiber cement doesn't cup, warp, or check the way wood does when it goes through repeated wet-dry cycles, and it holds paint and caulk lines the way they're supposed to be held. Combined with a strong transferable warranty, it's a product we can install once and stand behind for the long haul — which is the whole point of doing this work correctly the first time.
What This Means for Your Project
If you love the look of cedar, that's a legitimate preference and we understand it. But we'd rather be upfront about what that look costs in upkeep here in Ferndale than sell you something we know needs constant attention to hold up against salt air, driving rain, and moss. That's why cedar isn't a product we install, and why James Hardie fiber cement is what goes on every home we work on.
