Snohomish Cedar Siding: What It Actually Takes to Keep It Looking Good
Cedar has a real following in Snohomish and across Snohomish County, and it's easy to see why. The grain, the warmth, the way it ages when it's cared for — there's a reason cedar shows up on so many older homes and cabins around the Puget Sound region. We're not here to talk anyone out of liking the look of cedar. We're here to talk honestly about what it takes to keep that look, because that's the part homeowners usually don't hear about until they're the ones paying for it.
What Cedar Gets Right
Cedar is a genuinely good wood for siding. It's naturally resistant to rot and insects compared to most other softwoods, thanks to oils in the wood itself. It has decent insulating value, it's lightweight and workable, and it's a renewable material. Stained or left to weather naturally, it has a texture and depth that manufactured products spend a lot of engineering trying to replicate. For a certain style of home — craftsman, Northwest modern, mountain cabin — cedar fits in a way that's hard to argue with on looks alone.
The Maintenance Reality
Looks alone aren't the whole story. Cedar is wood, and wood moves with moisture. In a climate like ours — driving rain off the Sound, a long stretch of gray, damp months, and moss season that seems to start earlier every year — that movement adds up to real, recurring work.
- Refinishing on a clock: Stain or sealant on cedar siding typically needs to be reapplied every 3 to 5 years, sometimes sooner on south- and west-facing walls that take the brunt of sun and driving rain. Skip a cycle and the wood starts absorbing moisture unevenly, which is where the real problems start.
- Moss and mildew: Cedar's natural oils resist rot for a while, but they don't stop moss, algae, or mildew from taking hold on a shaded, damp wall — and Snohomish gets more than its share of shaded, damp walls for a good chunk of the year. Once moss gets a foothold in the grain, cleaning it off without damaging the wood is a delicate job, not a pressure-washer afternoon.
- Cupping, splitting, and warping: Boards that take on and release moisture repeatedly over the years can cup, twist, or split at the ends. Once that starts, water gets behind the board, and what was a cosmetic issue becomes a moisture-intrusion issue.
- Caulk and fastener upkeep: Cedar shrinks and swells seasonally, which stresses caulk joints and fasteners over time. Both need periodic inspection and touch-up to keep water from finding its way behind the siding.
None of this means cedar was a bad idea for the people who chose it. It means cedar comes with a standing maintenance obligation that most homeowners underestimate when they're comparing sticker price at the time of installation. Over 15 or 20 years, the labor and materials for refinishing, cleaning, and repair can rival or exceed what the siding cost to install in the first place.
Why We Don't Install It
We made a call, as a company, to install only James Hardie fiber cement siding — not cedar, not vinyl, not the other wood or wood-composite products on the market. It's not that cedar is a defective product; installed and maintained correctly, it can last decades. Our concern is what happens when it isn't maintained on schedule, which is the norm rather than the exception once the excitement of a new siding job fades. We'd rather stand behind a product whose performance doesn't hinge on a homeowner remembering to restain it every few years, especially in a climate that punishes any lapse in upkeep as fast as ours does.
There's also the fire question. Cedar is combustible, which matters more every year as wildfire smoke and dry spells become part of a normal Pacific Northwest summer, even here on the wetter side of the Cascades. It's a factor we take seriously when we're the ones putting our name behind an installation.
What We Install Instead
James Hardie fiber cement is our standard for a simple reason: it's engineered to hold up without the ongoing labor cedar demands. It's non-combustible, it resists moisture, moss, and pest damage far better than wood, and it comes with a factory-applied ColorPlus finish that's baked on rather than brushed on — no restaining every few seasons. Hardie's HZ5 product line is specifically engineered for climates that see heavy, sustained moisture, which describes Snohomish and the rest of Snohomish County pretty well. It carries a strong transferable warranty when installed to Hardie's spec, and it holds its look for a long time with a fraction of the upkeep cedar requires.
