Orcas Island Siding Cedar Looks Beautiful. That's Not the Question.
Nobody argues that cedar siding looks bad. Real wood grain, warm color, a natural fit with the wooded lots and waterfront views around Orcas Island — cedar has earned its reputation as a handsome siding choice. The question homeowners need to ask isn't whether cedar looks good going up. It's what cedar demands from them for the next twenty or thirty years, and whether San Juan County's climate makes that a fair trade.
What Cedar Actually Requires
Cedar is a natural wood product, and wood moves, absorbs moisture, and breaks down biologically no matter how well it's milled or installed. To keep cedar siding performing the way it's supposed to, a homeowner is signing up for an ongoing maintenance schedule, not a one-time install:
- Re-staining or re-sealing every 3 to 5 years, sooner in shaded or damp-prone spots
- Regular inspection for checking, cupping, and splitting as boards expand and contract
- Caulking and touch-up paint wherever finish wears thin at butt joints and fastener heads
- Active moss and mildew removal, since bare or weathered cedar is an easy surface for spores to take hold on
- Prompt repair or replacement of any board that starts to rot, before it spreads to neighbors
That's not a knock on cedar as a material — it's simply what an organic, moisture-permeable wood product needs to hold up. In a dry inland climate, that maintenance schedule is manageable. On Orcas Island, it's a different story.
Why San Juan County's Climate Is Hard on Cedar
Orcas Island sits in the marine air of the San Juan Islands, and that environment stacks several stresses on wood siding at once. Salt air off the water accelerates the breakdown of finishes and fasteners, leaving cedar exposed to moisture sooner than the coating schedule assumes. Driving rain off the Sound finds its way into end grain, seams, and any spot where caulking has started to fail — and once water gets behind a board, it doesn't dry out quickly in our marine humidity. Add in a long moss season that stretches through the wet months, and you have north-facing walls, tree-shaded lots, and anywhere airflow is limited turning green well before the next scheduled cleaning.
None of this means cedar "fails." It means cedar needs consistent, disciplined upkeep in exactly the kind of climate where upkeep is easiest to fall behind on — because ladders, scaffolding, and stain crews are harder to schedule around island weather windows, and a missed year or two of maintenance compounds fast in salt air and standing moisture.
The Real Cost Isn't the Install
Cedar siding is often competitively priced going in. The real cost shows up over the ownership period — recoating labor, moss treatments, spot repairs, and eventually board replacement in the areas that took the worst of the weather. Homeowners who plan to sell within a few years sometimes accept that trade-off. Homeowners planning to stay, or who don't want a recurring line item on their home maintenance calendar, are the ones who ask us the hardest questions about cedar — and those are fair questions to ask before signing a contract.
| Factor | Cedar Siding |
|---|---|
| Refinishing interval | Every 3-5 years, often sooner near the water |
| Moss/mildew exposure | High on shaded, north-facing, or tree-covered walls |
| Moisture behavior | Absorbs and releases moisture; prone to cupping and checking |
| Salt air resistance | Finish breaks down faster in marine environments |
| Fire resistance | Combustible, like all solid wood siding |
Why We Standardized on James Hardie Fiber Cement
We made a decision as a company: we install James Hardie fiber cement siding, and we don't install cedar. That's not because cedar is a bad product — it's because we don't think it's the right long-term answer for homes in this specific climate, and we'd rather stand behind one system we trust completely than offer several we have reservations about.
James Hardie's HZ5 product line is engineered specifically for climates like ours — cold, wet, and salt-exposed. Fiber cement doesn't absorb moisture the way wood does, so it isn't prone to the same cupping, splitting, and rot cycle. It's non-combustible, which matters to insurers and to homeowners thinking about wildfire risk in the Pacific Northwest. And the factory-applied ColorPlus finish is baked on and warranted against fading and peeling for decades, which means no re-staining schedule dictating your summers. Correctly installed to Hardie's specifications — proper flashing, fastening, and clearances — it's a system built to shrug off exactly the conditions that make cedar maintenance-heavy here: salt air, driving rain, and moss.
We're not asking you to take our word for it sight unseen. We're happy to walk your specific property, talk through what your walls are exposed to, and explain honestly where cedar would and wouldn't hold up if you already have it. If you're planning new siding and want a straight answer about what will actually hold up on Orcas Island, we'd like to give you one.
