Why Cedar Still Turns Heads
There's a reason cedar siding never fully goes out of style. It's a real, natural material with grain, color variation, and a warmth that manufactured products spend a lot of marketing money trying to imitate. Western red cedar is grown right here in the Pacific Northwest, it smells good on installation day, and a freshly finished cedar home looks genuinely handsome. We understand the appeal. Homeowners in Sudden Valley call us about cedar all the time, usually because they've seen an older cabin-style home on the lake with cedar siding that's aged into a nice silvery patina, or they're chasing that classic Northwest cabin look for a remodel.
What we don't do is sell homeowners on that look without being honest about what it takes to keep cedar siding performing — not just looking good in year one, but actually protecting the house in year fifteen. This page is about that gap between the romance of cedar and the maintenance reality of owning it here, on the water, in Whatcom County.

What Cedar Siding Actually Requires
Cedar is a wood product. Like any exterior wood, it needs a continuous, intact finish to keep water out of the fibers. Once that finish fails — and finishes on wood siding always fail eventually — the wood itself starts absorbing moisture, and that's when the real problems begin.
The Refinishing Cycle
Whether you finish cedar with solid stain, semi-transparent stain, or paint, you're signing up for a recurring maintenance cycle, not a one-time job. Semi-transparent stains typically need reapplication every 2-4 years on sun- and rain-exposed elevations. Solid-body stains and paints can stretch that out, often 5-7 years under good conditions, but they also hide the wood grain that's the whole reason people choose cedar in the first place. Either way, this isn't optional maintenance you can skip a cycle on — it's the thing standing between your siding and rot.
Caulk, Joints, and Fasteners
Cedar siding has seams, butt joints, and nail heads, and every one of them is a place water can get behind the finish. Caulking dries out and cracks well before most homeowners think to check it. Nail heads, especially on older installations, can rust and stain the wood or work loose as the wood expands and contracts with our wet winters and dry summer stretches.
The Whatcom County Climate Problem
Sudden Valley sits right on Lake Whatcom, and that setting is beautiful — it's also tough on wood siding in specific ways. Homes here deal with a combination that's harder on cedar than a drier inland climate would be:
- Driving rain off the lake pushes water sideways into siding, not just straight down, which stresses joints and finish edges more than a calm rain would.
- Salt-tinged marine air moving in off Bellingham Bay and the Puget Sound corridor accelerates finish breakdown and corrodes exposed fasteners faster than an inland home would experience.
- Extended moss and algae season — our mild, damp winters give moss, algae, and mildew months of ideal growing conditions on north-facing and shaded siding, and once organic growth takes hold on wood, it holds moisture against the surface.
None of that is a knock on cedar as a material. It's simply the honest description of the environment the siding has to survive in, and it's why maintenance intervals that work fine in, say, eastern Washington don't hold up the same way on a shaded, lake-facing wall in Whatcom County.
Moisture, Rot, and the Parts You Can't See
The failures that actually cost homeowners money aren't usually the ones you can see from the driveway. They're the ones behind the siding.
When a finish fails on a cedar board and nobody catches it for a season or two, the board starts wicking moisture. Wood siding that stays damp — especially in shaded, low-airflow areas like the north side of a home tucked into trees, which describes a lot of Sudden Valley lots — is exactly the environment that supports rot and provides a soft target for carpenter ants and other wood-destroying insects. By the time rot shows up as a visibly soft or discolored board, there's a good chance moisture has already reached the sheathing or framing behind it. That's no longer a siding repair; that's a structural repair with siding work attached to it.
This is the core of the maintenance truth about cedar: the material itself is durable when it's dry, but keeping it dry is a permanent, recurring job — not a project you finish once.
The Real Cost Over Time
Cedar siding's upfront material cost isn't wildly different from a quality fiber cement product, so the comparison that actually matters is lifecycle cost — what you spend to keep it protected over 20-30 years of ownership.
| Factor | Cedar Siding | James Hardie Fiber Cement |
|---|---|---|
| Finish/refinish cycle | Every 2-7 years depending on finish type and exposure | ColorPlus factory finish backed by a separate finish warranty; repainting is a homeowner choice, not a requirement |
| Moisture vulnerability | High if finish is neglected — wood absorbs and holds water | Engineered to resist moisture damage; won't rot from water absorption |
| Insect susceptibility | Attractive to carpenter ants, wood-boring insects if damp | Not a food or nesting source for wood-destroying insects |
| Combustibility | Combustible wood product | Non-combustible fiber cement |
| Moss/algae exposure | Growth holds moisture against wood, accelerating decay | Growth can be washed off without compromising the substrate underneath |
| Typical warranty | Varies by finish product; wood itself isn't warrantied against rot | Long-term, transferable manufacturer warranty on the siding itself |
None of this means cedar is a bad product — it means cedar and fiber cement are built around two different maintenance philosophies. Cedar rewards an owner who's committed to staying on top of refinishing on schedule. Fiber cement is built for owners who want that burden mostly engineered out of the equation.
Insurance and Resale Considerations
A couple of practical side effects of choosing wood siding are worth knowing about before you commit. Some insurance carriers price homeowner's policies slightly differently based on exterior combustibility, and a non-combustible siding can be a small point in your favor, particularly relevant given how much of Whatcom County's wildland-urban interface risk gets discussed regionally. On resale, a cedar exterior that's been well-maintained is an asset — but a cedar exterior with visible finish failure, graying in patches, or soft boards reads as deferred maintenance to a buyer's inspector, and it often becomes a negotiating point at exactly the wrong time.
A Homeowner's Cedar Maintenance Checklist
If you already own cedar siding, or you're weighing it for a project, here's what actually keeping it protected looks like on a realistic schedule:
- Inspect all elevations at least once a year, with extra attention to north-facing and shaded walls where moss and mildew take hold first.
- Wash siding annually to remove pollen, moss spores, and algae before they establish a foothold — a soft wash, not high-pressure, to avoid driving water into seams.
- Re-caulk joints, trim, and penetrations as soon as cracking or gaps appear, not on a fixed schedule.
- Plan and budget for full refinishing on the interval your specific stain or paint product requires — don't let it slide a season "to see how it holds up."
- Check and touch up any exposed or rusting fasteners before they stain or loosen boards.
- Trim back vegetation and tree cover that keeps any wall shaded and damp longer than the rest of the house.
- After any finish failure is spotted, address it promptly — a small refinish job now is far cheaper than a board and sheathing replacement later.
Why We Standardized on James Hardie Instead
We made a deliberate choice as a company to install only James Hardie fiber cement siding, and cedar's maintenance demands are a big part of why. We got tired of watching well-built, well-maintained cedar homes still end up with hidden rot because a homeowner missed one refinish cycle during a busy stretch of life, or because a shaded, lake-facing wall held moisture longer than anyone realized. That's not a judgment on cedar as a material — it's a judgment on what we're willing to warranty our workmanship against.
James Hardie's HZ5 product line is engineered specifically for climates like ours — freeze-thaw cycles, sustained damp weather, and coastal-influenced air. The ColorPlus factory finish is baked on under controlled conditions rather than applied on-site, which is a meaningfully different process than field-applied stain, and it comes with its own finish warranty. The board itself is non-combustible and isn't a food source for the insects that go after cedar. For a lake community like Sudden Valley, where a lot of homes sit close to trees, moisture, and shade, that combination solves the exact problems cedar struggles with here.
If you already have cedar siding on your home and it's well-maintained, there's no urgency to rip it off — a good maintenance routine can keep it performing for years. But if you're facing a refinish that's overdue, boards showing early rot, or you're planning a full re-side and want to stop budgeting for recurring refinishing work, that's the conversation worth having.
We're happy to take a look at your siding, tell you honestly what condition it's in, and walk through what a switch to James Hardie fiber cement would look like for your home. Reach out for a free, no-pressure estimate — there's no obligation, and no hard sell either way.
