Blaine Cedar Has a Real Appeal — We're Not Pretending Otherwise
Cedar siding shows up on a lot of homes around Blaine and the rest of Whatcom County, and it's not hard to see why. Western red cedar is a Pacific Northwest native material, it has a warm, natural grain that no engineered product fully replicates, and it ages into a silvery patina that some homeowners genuinely love. If you want the look of a true wood exterior, cedar delivers something fiber cement and vinyl can only approximate.
We get asked about cedar often enough that it's worth laying out, plainly, what owning a cedar-sided home actually involves once the installation crew leaves and the maintenance clock starts running. This isn't a knock on cedar as a material. It's an honest account of why we, as a contracting company, made the decision not to install it — and why that decision has everything to do with this specific stretch of coastline.
What Cedar Does Well
To be fair to the material: cedar is naturally resistant to insects and has decay-resistant properties compared to many other softwoods, thanks to natural oils in the wood. It's lightweight, it's a renewable resource, and when it's properly finished and maintained on a strict schedule, it can last for decades. Repairs to individual boards are usually straightforward compared to some manufactured sidings. None of that is in dispute.
The issue isn't whether cedar can perform well. It's whether it performs well without a level of ongoing attention that most homeowners don't sign up for when they picture "new siding."
The Maintenance Cycle Nobody Puts on the Brochure
Cedar siding is not a set-it-and-forget-it exterior. It's a finish system that has to be actively managed, and the finish is what's actually protecting the wood underneath. Once that finish starts to fail — and it does, on a predictable schedule — the wood is exposed to moisture, and moisture is what causes almost every serious cedar siding problem we see.
| Task | Typical Interval | Why It Matters |
|---|---|---|
| Re-stain or re-seal | Every 2-4 years (semi-transparent stain) or 4-7 years (solid stain/paint) | UV and moisture break down the finish; once it fails, bare wood absorbs water |
| Caulking inspection & touch-up | Annually | Joints and seams open up as wood moves seasonally; failed caulk is a direct water path |
| Moss and algae removal | Annually, more on shaded/north-facing walls | Organic growth holds moisture against the wood and accelerates rot |
| Board inspection for cupping, splitting, checking | Annually | Early detection prevents small repairs from becoming full board or panel replacement |
| Full repaint/refinish after neglect | Reactive, often more expensive than a scheduled maintenance cycle | Deferred maintenance compounds — bare wood degrades faster than finished wood |
None of these are one-time costs. They repeat for the life of the siding, and skipping a cycle doesn't just delay the work — it usually makes the next round more expensive.
Who Actually Does This Work
Some homeowners do their own re-staining. Most don't, either because of the labor, the height of a two-story wall, or simply not wanting to spend a weekend every few years on it. That means hiring it out, and repeated professional refinishing over the life of a house adds up to a real, recurring line item in the home maintenance budget — one that vinyl, and non-combustible fiber cement with a factory-applied finish, simply don't carry.
How Blaine's Climate Loads the Dice Against Wood
This is the part that's specific to where we work, not a generic cedar critique. Blaine sits right on the Salish Sea, and homes here deal with a combination of conditions that's genuinely tougher on wood siding than a lot of other parts of the country:
- Salt air. Proximity to Semiahmoo Bay and Drayton Harbor means airborne salt is a constant, low-level presence. Salt is hygroscopic — it pulls moisture out of the air and holds it against surfaces, which keeps wood siding damper for longer after every rain.
- Driving rain. Whatcom County storms coming off the Pacific don't just fall straight down; wind-driven rain gets pushed sideways into wall assemblies, finding every gap in caulking or every hairline check in a cedar board.
- A long moss and algae season. Between the marine humidity and the mild, wet winters typical of this corner of Washington, north- and west-facing walls stay damp for extended stretches. That's exactly the environment moss, algae, and mildew need to take hold on a wood surface.
Put those three together and you get a climate that's actively working against a finish coating, year-round, not just during one rainy season. Homeowners further inland or in drier climates can sometimes stretch cedar maintenance intervals. On this coastline, stretching them is how small problems become rot.
Where Moisture Problems Actually Start
The failure pattern we see with neglected or aging cedar isn't usually dramatic. It's slow: a coating starts to chalk and thin, a caulk joint opens a hairline gap, a board cups slightly at the edge. Water gets in behind the finish, and because wood is porous, it doesn't just sit on the surface — it moves into the board. Cycles of wetting and drying, especially in a mild coastal climate where things rarely dry out completely between rain events, are what eventually cause soft spots, splitting, and, at the sheathing level, more serious rot that isn't visible from the outside until it's advanced.
This is also where installation quality matters more with cedar than with a lot of other siding types. Board spacing, fastening, flashing details, and back-priming all affect how well the material sheds water and how it moves with humidity changes. Get those details wrong, and a homeowner can end up fighting moisture problems years ahead of schedule regardless of how diligent they are about refinishing.
The Honest Cost Picture
We don't publish cedar re-siding numbers because every home and every finish schedule is different, but the pattern holds across the industry: a wood siding system's total cost isn't the installed price, it's the installed price plus a recurring maintenance bill for as long as you own the house. That's the trade-off homeowners are actually making, whether or not it's spelled out at the point of sale.
A Quick Self-Check Before You Choose Wood Siding
- Are you comfortable budgeting for re-staining every 2-4 years, indefinitely?
- Do you have (or want to hire) someone to inspect caulking and joints annually?
- Is your home's exposure mostly shaded or north-facing, where moss and moisture linger longest?
- Are you prepared to address soft or cupped boards quickly rather than waiting for a bigger repair?
- Does the home sit close enough to the water that salt air is a daily factor, not an occasional one?
If the honest answer to most of those is "no" or "not really," cedar is likely to become a source of frustration rather than the low-maintenance exterior most homeowners actually want.
Why We Standardized on James Hardie Instead
We made a deliberate call as a company to install only James Hardie fiber cement siding, and cedar's maintenance profile is a big part of that reasoning. Hardie's HZ5 product line is engineered specifically for climates like ours — freeze-thaw cycles, sustained moisture, and coastal exposure — and it comes with a factory-applied ColorPlus finish rather than a field-applied stain that starts degrading the moment it's exposed to weather. Fiber cement doesn't rot, and it isn't a food source for the moss and mildew that thrive in Whatcom County's wet season the way bare or under-maintained wood is.
It's also non-combustible, which matters to insurers and to homeowners thinking about wildfire exposure, and it carries a strong transferable warranty backed by a large manufacturer rather than resting entirely on how well a homeowner keeps up with refinishing. We're not saying cedar is a bad product — we're saying that after years of doing exterior work in this specific climate, we don't think it's the right long-term bet for most homeowners here, and we'd rather be straight about that than sell a product we don't believe holds up to Blaine's weather without a maintenance commitment most people underestimate.
What This Means for Your Project
If you love the idea of a wood exterior and you're genuinely ready for the upkeep, that's a legitimate choice — just go in with eyes open about the schedule above. But if what you actually want is an exterior that looks good for decades without becoming a recurring project, that's exactly the gap Hardie fiber cement was built to close, and it's why it's the only siding system we put on homes.
Every house and every budget is different, and the right answer depends on your home's exposure, your timeline, and what you want to be dealing with five or fifteen years from now.
