Sudden Valley Siding Cedar Has Real Appeal — and Real Demands
Cedar siding has a following for good reason. It looks warm and natural, it's a renewable material, and a freshly finished cedar home has a character that manufactured products spend a lot of effort trying to imitate. If you grew up around cedar-clad homes in the Pacific Northwest, the appeal isn't hard to understand. But there's a gap between how cedar looks on day one and what it takes to keep it looking that way through a Sudden Valley winter, and that gap is the whole reason we're writing this page.
What Cedar Actually Requires, Year After Year
Cedar is wood. It expands, contracts, absorbs moisture, and breaks down under UV exposure like any other wood product — it's just naturally more rot-resistant than most species, which is where its reputation comes from. That resistance is relative, not absolute, and it depends entirely on an ongoing maintenance schedule that most homeowners underestimate when they first install it.
- Refinishing on a clock: Stained cedar typically needs to be recoated every 3-5 years, and painted cedar isn't far behind. Skip a cycle and you're not just losing curb appeal — you're losing the moisture barrier that protects the wood underneath.
- Caulking and sealant checks: Every seam, joint, and butt end is a potential water entry point. These need to be inspected and re-sealed regularly, not just at install.
- End-grain protection: The cut ends of cedar boards absorb water far faster than the face grain. Field-cutting during install and neglecting to seal those cuts is one of the most common ways cedar siding fails early — and it's easy to miss even with careful crews.
- Moss and algae removal: Cedar's rough, absorbent surface gives moss and algae something to grab onto, which brings us to the local part of this conversation.
Whatcom County's Climate Doesn't Do Cedar Any Favors
Sudden Valley sits close enough to Lake Whatcom and the broader Whatcom County weather pattern that homes here deal with a long, wet season nearly every year. Driving rain off the water, persistent cloud cover, and a moss season that can run for months are simply part of living here. That combination is tough on any siding, but it's particularly hard on a porous, organic material like cedar. Moisture that would evaporate off a home in a drier climate can sit against cedar siding here for weeks at a stretch, and moss doesn't just look bad — its root structure holds water directly against the wood, accelerating rot in exactly the spots you can't see until a board is already soft.
Homes closer to the water, or in shaded, north-facing exposures common throughout the area, see this faster than homes in open, sunny lots. If your property has mature trees or sits in a low-airflow pocket — common around Sudden Valley's wooded lots — expect the maintenance clock to run faster than the general 3-5 year guidance above.
The Honest Cost Math
Cedar siding is often priced competitively against fiber cement up front, but the comparison breaks down once you account for what happens after installation. A homeowner who properly maintains cedar — refinishing on schedule, cleaning moss, resealing joints — is looking at a recurring cost and labor commitment for as long as they own the home. Skip that maintenance, which happens more often than not once the "new house" feeling wears off, and you're looking at board replacement, rot repair, and potentially compromised sheathing behind the siding within a decade or two, especially in a wet coastal climate like ours.
None of this makes cedar a bad product. It makes cedar a product that asks a lot of its owner, indefinitely, in a climate that doesn't cut it any slack.
Why We Standardized on James Hardie Instead
We made a decision as a company to install only James Hardie fiber cement siding, and cedar's maintenance profile is a big part of why. Hardie's HZ5 product line is engineered specifically for climates like ours — it doesn't absorb water the way wood does, it isn't a food source for moss and algae the way cedar's organic surface is, and it carries a factory-applied ColorPlus finish that's warrantied against fading for a set number of years, so you're not on a 3-5 year recoating cycle to protect the material underneath.
It's also non-combustible, which matters increasingly to insurers and homeowners alike, and it holds up to the driving rain and freeze-thaw cycling that Whatcom County sees every winter without the swelling, cupping, or checking that wood siding is prone to over time. When it's installed to Hardie's specifications — correct clearances, proper flashing, factory-cut ends wherever possible — it's about as close to "install it and stop worrying about it" as siding gets.
We're not going to tell you cedar is a bad material — it isn't. We're telling you that after years of watching what our climate does to wood siding, we stopped installing it, because we didn't want to sell homeowners a product that looks great for a photo and then becomes a recurring maintenance project for the next twenty years.
