Cedar's Real Appeal (And Why We Understand the Draw)
We're not going to pretend cedar siding is a bad-looking product, because it isn't. Real wood grain, warm color, the ability to stain it to whatever tone fits a craftsman or cottage-style home — cedar has a genuine, natural look that manufactured products spend a lot of engineering effort trying to imitate. Western red cedar is also a regional material, milled not far from Skagit County, and there's an understandable pull toward using a wood product in a part of Washington known for its forests.
If cedar performed the way homeowners hope it will over a 20 or 30 year ownership window, we'd have less to say here. The problem isn't the wood itself. The problem is what happens to that wood once it's fastened to a wall and left to face an Anacortes winter, year after year, for decades.

What Cedar Siding Actually Requires to Last Here
Salt Air and Coastal Exposure
Anacortes sits right on the water, and a meaningful share of the homes we look at are within a mile or two of Rosario Strait, Fidalgo Bay, or the marinas downtown. Salt-laden air accelerates the breakdown of wood fibers and finish coatings faster than it does further inland. Fasteners corrode sooner. Paint and stain film fail sooner. None of that is unique to cedar — but cedar's performance depends entirely on an intact protective finish, so anything that shortens the life of that finish shortens the life of the siding's protection.
Driving Rain and Moisture Cycling
Skagit County gets wind-driven rain off the Strait that hits siding at an angle, not just straight down. Wood siding manages moisture by absorbing it and releasing it — that's simply how wood behaves. Every wet-dry cycle causes the boards to swell and shrink slightly. Do that hundreds of times a year for years, and you get the checking, cupping, and joint movement that eventually opens paths for water to get behind the siding rather than shed off of it.
Moss, Mildew, and the Long Wet Season
Anacortes doesn't get a short, sharp wet season — it gets a long one, with plenty of overcast, humid stretches even outside the heaviest rain months. That's ideal growing conditions for moss and mildew on any organic material, and cedar is organic material. On north-facing walls, under eaves with limited sun exposure, and near mature trees, we regularly see moss colonization on wood siding within a few years of a fresh finish job, especially where a house sits close to landscaping that keeps the wall shaded and damp.
The Maintenance Reality: What Homeowners Actually Sign Up For
Cedar siding is not a install-it-and-forget-it product. To get a normal service life out of it in a marine climate like ours, it needs an ongoing maintenance schedule that most homeowners underestimate when they're comparing materials up front.
- Re-staining or re-sealing every 3 to 5 years, sooner on sun- and rain-exposed elevations
- Annual inspection for checking, cupping, or separated joints, especially after winter storms
- Regular cleaning to remove moss, algae, and mildew buildup before it stains or holds moisture against the wood
- Prompt caulking and touch-up at any exposed end grain, since end grain absorbs water many times faster than the face of the board
- Vigilant gutter and downspout maintenance, since overflow or splash-back onto cedar accelerates rot at the lower courses
- Periodic check of fasteners and flashing details, since corrosion or movement here is often the first sign of a bigger moisture problem
None of that is exotic work, but it's real, recurring cost and effort — and it has to actually happen on schedule. A missed re-coat cycle doesn't just mean the house looks a little tired; it means the wood is unprotected during exactly the seasons it needs protection most.
Where We See Cedar Siding Fail in the Field
Checking and Cupping
As boards absorb and release moisture unevenly across their thickness, they check (surface cracking) and cup (curl across the width). Once a board has checked, water can track into the crack and sit there, which speeds up decay from the inside rather than the surface — often invisible until the finish is well past due.
Rot at Butt Joints and Fasteners
The seams where boards meet, and the nail penetrations holding them on, are the weak points in any lap siding system. On cedar, these are also the spots most prone to trapping moisture, and it's common to find soft, decayed wood at butt joints on homes where the rest of the field looks presentable from the ground.
Insect and Moss Colonization
Wood siding that stays damp for extended periods becomes attractive to carpenter ants and other wood-seeking insects, in addition to moss and mildew. This tends to show up first in shaded, low-airflow areas — exactly the wall conditions common on lots with mature landscaping or tight side-yard setbacks, which describes a lot of established Anacortes neighborhoods.
Cost Over Time: Cedar vs. Fiber Cement
Cedar's upfront material cost is often close to premium fiber cement, so the real cost difference shows up over the ownership timeline, not on day one.
| Factor | Cedar Siding | James Hardie Fiber Cement |
|---|---|---|
| Finish maintenance | Re-stain/re-seal every 3-5 years | ColorPlus factory finish, no repainting for many years |
| Moisture behavior | Absorbs and releases; prone to checking/cupping | Engineered to resist moisture-driven swelling and rot |
| Moss/mildew resistance | Organic surface, susceptible especially in shade | Non-organic composition, far less hospitable to growth |
| Fire rating | Combustible | Non-combustible |
| Typical inspection interval | Annual, with active upkeep required | Periodic, largely passive between finish cycles |
| Warranty | Varies by mill; often limited or none on finish | Strong manufacturer-backed, transferable warranty |
Over a 20-30 year window, the cumulative cost of cedar's maintenance schedule — labor, materials, and the risk of deferred upkeep turning into repair work — is where it tends to lose ground to a lower-maintenance material, even though the sticker price at installation can look competitive.
Fire and Insurance Considerations
Cedar, like any wood product, is combustible. That's a real consideration in Washington regardless of region, and it's increasingly something insurance carriers and underwriters are factoring into premiums and coverage terms for homes with wood exteriors. Fiber cement siding is non-combustible, which can matter both for wildfire exposure and for standard structure fire risk. We don't oversell this point — a well-built home with cedar siding isn't a fire hazard on its own — but it's a legitimate factor in the material comparison that homeowners deserve to hear plainly.
Why We Standardized on James Hardie Instead
ColorPlus Factory Finish
Hardie's ColorPlus finish is baked on at the factory under controlled conditions, not brushed or sprayed on site. That gives it more consistent coverage and adhesion than a field-applied stain, and it's backed by its own finish warranty — removing the recurring re-coat cycle that drives so much of cedar's long-term cost and effort.
HZ5 Engineered for the Pacific Northwest
James Hardie makes climate-specific product lines, and the HZ5 formulation is engineered for regions with our combination of moisture, moderate temperatures, and freeze-thaw exposure. That's a meaningful difference from a general-purpose wood product that behaves the same whether it's installed in Anacortes or a dry inland climate.
Warranty Structure
Hardie backs its fiber cement products with a strong, transferable warranty — a real asset when a home eventually sells, since a buyer's inspector and lender both take exterior condition and warranty coverage seriously. Cedar's warranty coverage, where it exists at all, is typically much more limited and tied to finish products rather than the siding material itself.
What This Means for Your Project
We made the decision to install only James Hardie fiber cement siding because it's the product we can confidently install once, back with a real warranty, and expect to perform with reasonable maintenance for decades in this exact climate — salt air, driving rain, and a moss season that doesn't leave much room for a material that depends on a perfect, uninterrupted upkeep schedule. Cedar can look beautiful the day it goes up. Our job is to think about what a Skagit County wall looks like in year fifteen, not just year one.
