Bellingham Why Cedar Still Comes Up in Bellingham
Cedar siding has a long history in the Pacific Northwest, and for good reason. It's a regional material, it looks the part on a craftsman or a cabin-style home near the water, and a lot of older houses in neighborhoods like Fairhaven and the Lettered Streets still wear it. Homeowners planning a re-side often ask about it first, usually because a neighbor has it, or because it matches the character of an older Bellingham home. That's a fair starting point. But the question that actually matters isn't "does cedar look good going up" — it's "what does it take to keep looking good, year after year, in this climate." That second question is where a lot of cedar projects run into trouble.
What Cedar Actually Gets Right
We're not going to pretend cedar is a bad material — it isn't. It deserves a fair, honest look before we explain why we don't install it.
- It's a renewable, natural material with genuine warmth and grain that manufactured products try to imitate.
- Western red cedar has natural oils that resist decay and insects better than most other softwoods.
- It's lightweight, easy to mill into different profiles (shingle, shiplap, board-and-batten), and forgiving to install.
- When it's maintained on schedule, a cedar-clad home can look excellent for decades.
That last point is the catch. "When it's maintained on schedule" is doing a lot of work in that sentence, and it's the part most homeowners underestimate when they're standing in a showroom looking at a sample board.
The Climate Cedar Has to Survive Here
Bellingham sits right on the Salish Sea, and that location shapes everything about how exterior wood ages here. Whatcom County gets driving, wind-blown rain off Bellingham Bay for much of the year, not just the occasional storm — moisture gets pushed into seams, laps, and end grain instead of running straight down the wall. Add a marine layer that keeps humidity elevated through spring and fall, and wood siding rarely gets a long, dry stretch to fully release the moisture it absorbs.
Then there's moss. Bellingham's moss season isn't a two-week nuisance — shaded, north-facing walls and anything near mature trees or close-set houses can stay damp enough to grow moss and algae for a good chunk of the year. Add salt air off the water in neighborhoods closer to the bay, and you've got three separate stressors — constant moisture, prolonged shade-driven growth, and salt exposure — all working on the same painted wood surface at once. Any one of those is manageable. All three together, on a wood product, is a maintenance commitment, not a one-time purchase.
The Maintenance Cedar Actually Requires
This is the part that doesn't show up on the sample board. Cedar siding is a finished wood product, and the finish is what's actually protecting the wall — not the cedar itself. Once the finish starts to fail, the clock starts on rot, cupping, and checking.
| Task | Typical Frequency in Bellingham's Climate | Why It's Needed |
|---|---|---|
| Wash / soft-wash siding | Every 1-2 years | Removes moss, algae, and pollen buildup that traps moisture against the wood |
| Inspect caulking and trim joints | Annually | Driving rain finds any gap in caulk and pushes water behind the boards |
| Repaint or restain | Every 4-7 years (paint), 2-4 years (semi-transparent stain) | UV and moisture break the finish down faster on south/west exposures; failed finish lets water into the wood |
| Spot-repair or replace rotted boards | As found, usually during repaint prep | End grain, lap joints, and ground-contact areas fail first and are easy to miss until the finish is stripped |
| Check for woodpecker or insect damage | Ongoing, seasonal | Softened, moisture-damaged wood attracts pests more than sound wood |
None of these are unreasonable tasks in isolation. Stacked together, over 20-30 years of ownership, they add up to a real, recurring line item — in both money and attention — that doesn't go away as long as the siding is wood.
A Simple Homeowner Checklist
- Are you planning to repaint or restain on a 3-7 year cycle for as long as you own the home?
- Do you have shaded or north-facing walls that will need more frequent moss and algae removal?
- Is your home within a mile or two of Bellingham Bay, where salt air accelerates finish breakdown?
- Are you comfortable budgeting for board replacement when rot is found during repaint prep?
- If you plan to sell within 10-15 years, will a buyer's inspector see a wood siding maintenance history as an asset or a red flag?
Moisture, Rot, and the Repaint Cycle
Cedar's natural rot resistance is real, but it's relative — it slows decay, it doesn't stop it. Once the factory or field-applied finish starts to fail (and finishes fail on a schedule, not a whim), the wood underneath is exposed to exactly the moisture load Whatcom County delivers most of the year. Water gets into end grain at butt joints, behind trim, and around fasteners, and because cedar is a natural material, it doesn't dry evenly — you get cupping, checking, and localized soft spots long before the whole wall looks bad from the street. By the time a homeowner notices a problem, there's often already a repair involved, not just a repaint.
This is the honest trade-off with cedar: the material itself is genuinely good wood, but its long-term performance depends entirely on a maintenance schedule being followed without gaps, for the life of the siding. Skip two repaint cycles because of budget, a busy few years, or a change of ownership, and the damage compounds in ways that are expensive to fix — not just cosmetic.
Moss, Salt Air, and Coastal Wear
We mentioned moss and salt air above, but they deserve a closer look because they're specific to this region, not a generic siding concern. Moss growth on painted wood isn't just an appearance issue — moss and algae hold moisture against the surface, which accelerates finish breakdown and gives rot a head start in exactly the shaded, damp spots that already dry slowest. Homes tucked under trees, or with north walls that don't get much sun, are the ones we see with the worst wood siding problems in this county.
Salt air is a slower, quieter problem. It doesn't destroy wood the way it corrodes metal, but it does contribute to finish degradation and can leave a chalky, dulled look on paint and stain faster than it would inland. Combine that with the driving rain off the bay, and homes closer to the water need the tightest maintenance schedule of all — which is often the opposite of what a homeowner wants to hear about the house with the best view.
Cedar vs. Fiber Cement: The Cost Picture Over Time
Upfront material and installation cost for cedar can be competitive with — or sometimes less than — fiber cement, depending on the profile and grade. But upfront cost is only half the picture. Here's the honest comparison over a 20-year ownership window.
| Factor | Cedar Siding | James Hardie Fiber Cement |
|---|---|---|
| Finish | Field or shop-applied, fails on a 3-7 year cycle | Factory-baked ColorPlus finish, warranted separately from the substrate |
| Recurring maintenance | Washing, repainting, caulk inspection, spot repair | Periodic washing; no repainting cycle required |
| Moisture/rot risk | Ongoing risk if finish maintenance lapses | Fiber cement doesn't rot; engineered for wet climates |
| Fire performance | Combustible | Non-combustible |
| Typical warranty | Varies by installer; material itself carries limited or no manufacturer warranty | Long, transferable manufacturer warranty on both substrate and finish |
| 20-year cost driver | Labor-heavy repaint and repair cycles | Lower recurring cost; occasional caulk/touch-up only |
Neither product is "cheap" or "expensive" in an absolute sense — the real difference is where the money goes. With cedar, a meaningful share of the lifetime cost is repeated labor: scaffolding or ladders, prep, primer, paint, and the inevitable board replacement. With fiber cement, more of the cost is upfront, and the ongoing burden is much lighter.
Why We Install James Hardie Instead
We made the decision years ago to install James Hardie fiber cement exclusively, and cedar's maintenance profile is a big part of that decision. It's not that cedar is a bad product — it's that in a climate like Whatcom County's, with driving rain, a long moss season, and salt air in the coastal neighborhoods, we don't think it's fair to put a homeowner into a siding system that requires a strict, uninterrupted maintenance schedule to avoid real damage.
James Hardie's HZ10 product line is engineered specifically for climates like ours — it's built to handle sustained moisture exposure without the rot risk of a wood substrate. The ColorPlus factory finish is baked on and backed by its own warranty, so homeowners aren't on a 3-to-7-year repaint clock. It's non-combustible, which matters as wildfire smoke and dry summer stretches become more common even here on the wet side of the state. And the transferable warranty gives whoever owns the home next some real protection, not just a maintenance history to inherit.
We'd rather explain honestly why we don't install cedar than sell you something we don't believe holds up to Bellingham's weather over the long run.
What This Means for Your Project
If you're set on the look of cedar, there are ways to get a similar aesthetic with fiber cement — Hardie's shingle and lap profiles can echo that traditional Pacific Northwest look without the maintenance schedule underneath it. If you're earlier in the decision process, it's worth being honest with yourself about how much time and money you're willing to commit to repainting and repair over the next 20 years, not just what the siding costs to install this summer.
Every home and budget is different, and we're happy to walk through your specific situation — sun exposure, tree cover, distance from the water, and how long you plan to stay in the home — before recommending anything.
