Anacortes Cedar Siding Looks Great in the Showroom. Skagit County Weather Has Other Plans.
There's a reason cedar siding has stayed popular for decades: real wood grain, warm color, and a look that vinyl and composite products have spent years trying to imitate. If you've ever run your hand over a freshly finished cedar wall, you understand the appeal. We're not going to pretend otherwise.
What we will do is give you the honest picture of what cedar actually asks of a homeowner once it's on the wall — especially a wall facing Anacortes weather. Salt air off Fidalgo Bay, driving rain through the fall and winter, and a long, damp moss season every year are exactly the conditions that put real wood siding to the test.
What Cedar Gets Right
Before the trade-offs, credit where it's due:
- Natural insulation: Wood has better inherent R-value than most manufactured sidings.
- Authentic texture: Real cedar grain and knots can't be perfectly replicated by any engineered product.
- Renewable material: Properly harvested cedar is a natural, renewable resource.
- Repairable: Individual boards can be replaced without tearing off a whole wall section, if matched well.
If cedar siding is well-built, well-finished, and maintained on a strict schedule, it can perform for a long time. That "if" is the whole story.
The Maintenance Reality
Cedar is a natural material, which means it behaves like one — it moves with moisture, it feeds mold and moss in the right conditions, and it needs a protective finish that is actively renewed, not just applied once and forgotten.
Refinishing Isn't Optional
Whether you go with stain or paint, the finish on cedar siding is a sacrificial layer. It's meant to wear down and be reapplied — typically every three to seven years depending on exposure, product, and how much direct weather a given wall takes. South and west-facing walls that catch driving rain off the Sound will need attention sooner than a sheltered north wall. Skip a cycle and the wood starts absorbing moisture directly, which is where the real problems begin.
Moss, Mildew, and the PNW Damp Season
Anacortes and the rest of Skagit County get a long stretch of gray, wet months where surfaces stay damp for days at a time. Cedar siding in shaded areas, under eaves, or near landscaping that holds moisture is prone to mildew staining and moss growth. That's not a defect in the product — it's just what happens when organic wood sits in a marine, moisture-heavy climate without regular cleaning and inspection.
Salt Air Accelerates Everything
Properties near the water deal with airborne salt that speeds up finish breakdown and can contribute to fastener corrosion over time. It doesn't ruin cedar siding, but it does shorten the interval between maintenance cycles compared to the same house sitting further inland.
Caulking, Checking, and Board Movement
Wood expands and contracts with humidity swings. Over years, that movement opens up hairline checks in the wood and stresses caulked joints around trim, windows, and butt seams. Those small openings are where bulk water gets behind the siding — and once moisture is trapped behind cedar, rot can develop in places you can't see from the ground.
The Honest Cost Comparison
| Factor | Cedar Siding |
|---|---|
| Refinishing cycle | Every 3–7 years, sooner on exposed or coastal walls |
| Moss/mildew risk | Ongoing in shaded, damp areas — needs cleaning |
| Fire rating | Combustible, standard wood construction |
| Failure mode if neglected | Rot, cupping, board replacement |
None of this makes cedar a bad product. It makes it a high-commitment one. The homeowners who are happiest with cedar siding are the ones who go in knowing it's an ongoing relationship, not a one-time purchase.
Why We Standardized on James Hardie Instead
We stopped installing cedar, along with a handful of other siding products, because we got tired of watching well-intentioned homeowners fall behind on a maintenance schedule that real life doesn't always accommodate. When that happens with cedar, the wood pays the price.
James Hardie fiber cement gives us the durability profile we want to stand behind in this climate: it's non-combustible, it doesn't feed mold or moss the way organic wood can, and the ColorPlus factory finish is baked on and warrantied — no repainting cycle every few years. Hardie's HZ5 product line is engineered specifically for the kind of wet, marine, freeze-thaw conditions we get here in Skagit County, and it carries a strong transferable warranty that reflects real confidence in long-term performance.
You can still get a wood-grain, cedar-inspired look with Hardie's lap and shingle profiles — you just don't sign up for the refinishing treadmill to keep it looking right.
