Ferndale Cedar Looks Great On Day One. The Question Is Day 1,000.
Cedar has earned its reputation. It's a real wood, it smells good in the shop, it takes a stain beautifully, and there's a warmth to a cedar-clad home that manufactured products spend a lot of marketing dollars trying to imitate. If a homeowner in Ferndale asks us about cedar, we don't pretend it's a bad material. We tell them the truth: cedar is a beautiful siding choice for someone who's committed to maintaining it, and a frustrating one for someone who isn't. Our company made a decision years ago to install only James Hardie fiber cement siding, and cedar is one of the main reasons why. Here's the honest reasoning.
What Cedar Actually Does Well
- Natural insulating value. Wood has better inherent R-value than most claddings, cell for cell.
- Workability. It cuts, shapes, and fastens easily, which is part of why it's been a Pacific Northwest staple for generations.
- Renewable material. Properly harvested cedar is a renewable resource, and many homeowners like that.
- Character. Grain pattern and natural color variation give a look that's hard to fake.
None of that is in dispute. The problem isn't what cedar looks like when it goes up. It's what it takes to keep it looking that way.
The Maintenance Cedar Doesn't Advertise
Cedar is wood, and wood moves. It absorbs moisture and releases it as humidity and temperature change, and that cycle is what eventually causes cupping, checking, and splitting at the board level. To slow that down, cedar needs a film-forming stain or a penetrating oil finish reapplied on a regular schedule — typically every three to five years, sometimes sooner on south- and west-facing walls that take the most sun and weather. Skip a cycle or two and the wood starts absorbing water directly, which is where the real trouble begins.
Whatcom County doesn't make that schedule easier to keep. Ferndale sits close enough to the Strait of Georgia and Bellingham Bay that salt-laden air is a regular visitor, and salt air accelerates the breakdown of finishes and corrodes fasteners faster than an inland climate would. Add the driving rain that comes through on winter storms, and cedar siding here spends a lot of the year staying damp longer than it would in a drier region. That extended dampness is exactly what our long, mild, wet local moss season feeds on — moss and algae take hold readily on wood siding that doesn't dry out quickly, and once established, they hold moisture against the wall even longer, which speeds up rot at butt joints, end grain, and anywhere caulk has started to fail.
Where It Tends to Fail First
- End grain and butt joints — the most absorbent part of any board, and the first place rot typically starts.
- Fasteners — nail corrosion in a salt-air environment can cause staining and eventually loosens boards.
- Lower courses — splash-back from grade level keeps the bottom rows wetter than the rest of the wall.
- North-facing and shaded walls — slower to dry, more prone to moss and mildew growth.
The Real Cost Is Spread Over Years, Not Paid Up Front
Cedar siding is often competitively priced going in. Where it catches homeowners off guard is the recurring cost afterward: refinishing labor every few years, individual board replacement as sections fail, and the fact that deferred maintenance on wood siding doesn't stay cosmetic — it turns into sheathing and framing repairs if water gets behind the cladding. Cedar is also a combustible material, which matters to some homeowners for insurance and wildfire-adjacent reasons, even in a wetter climate like ours. None of this means cedar is a bad product. It means cedar asks for an ongoing commitment that a lot of busy homeowners underestimate when they're standing in a showroom looking at a sample board.
Why We Install James Hardie Instead
James Hardie fiber cement is non-combustible, engineered specifically for wet climates in its HZ5 product line, and finished at the factory with ColorPlus technology — a baked-on finish that's far more consistent and far more resistant to fading and moisture damage than a field-applied stain, and that doesn't ask for repainting on a three-to-five-year clock. It resists moss and algae growth much better than raw wood, holds up to salt air without the corrosion concerns of bare cedar, and comes with a strong, transferable warranty that backs up how it's built to perform over the long run. For a coastal Whatcom County home taking on driving rain, salt air, and a long damp season, that's the trade-off that makes sense to us: less upkeep, more predictable performance, and a finish that still looks right a decade in.
