Birch Bay Siding Cedar Has Real Appeal — We Won't Pretend Otherwise
Cedar siding has a look that's hard to argue with. The grain, the warmth, the way it weathers to a silvery gray if you let it — a lot of homeowners in Birch Bay grew up around cedar-clad houses and want that same character on their own home. Western red cedar is a genuinely good wood: naturally resistant to rot and insects compared to most softwoods, lightweight, and easy for a crew to work with on cuts and trim details. If wood siding were maintenance-free, we'd probably still be installing it.
It isn't maintenance-free, though. And after years of tear-offs, repairs, and conversations with homeowners about what it actually takes to keep cedar looking good on the Whatcom County coast, we made the call to stop installing it. Here's the honest version of why.
What Birch Bay's Climate Does to Wood Siding
Birch Bay sits right on the water, which means every board on the exterior of a house here deals with three things at once: salt-laden air off the bay, long stretches of driving rain through fall and winter, and a moss season that can run half the year in the shaded, north-facing spots. Any one of those is manageable. Together, they're hard on wood.
Salt air accelerates the breakdown of finishes — paint and stain give up their protective qualities faster near the water than they would ten miles inland. Driving rain, especially wind-driven rain hitting a wall at an angle, finds its way into end grain, seams, and any spot where a finish has thinned. And moss doesn't just sit on the surface — it holds moisture against the wood, which is exactly the condition that leads to rot, especially in siding that stays shaded most of the day.
Cedar resists rot better than most woods when it's dry. The problem in this climate is that it doesn't get to stay dry for long.
The Maintenance Cedar Actually Requires
This is the part that doesn't always come up in the sales conversation. To keep cedar siding performing — not just looking okay, but actually shedding water the way it's supposed to — it needs:
- Refinishing (stain or paint, depending on the look) roughly every 3-5 years, often sooner on wall faces exposed to weather or salt spray
- Regular washing to keep moss and mildew from establishing on shaded or north-facing walls
- Prompt caulking and sealing at butt joints, corners, and anywhere end grain is exposed
- Fast repair of any cracked, split, or cupped boards before moisture gets behind them
- Periodic inspection behind and around trim, since hidden rot on wood siding often isn't visible until it's advanced
None of that is unreasonable to ask of a homeowner in a dry climate. In a place where the siding is dealing with salt air, sustained rain, and moss for a good chunk of the year, it turns into a real, recurring commitment — and the interval between refinishing jobs tends to shrink rather than stretch out once a house is a few years in.
Where the Trade-Off Really Shows Up
The failures we've seen on cedar siding almost never come from the wood itself failing on its own. They come from maintenance falling a season or two behind — a missed refinish cycle, moss left to sit against a wall, a cracked board that didn't get caught early. Once water gets behind cedar siding, it can travel and cause damage that isn't obvious from the outside until a repair is already needed. That's a hard thing to plan around for homeowners who don't want exterior maintenance to be a recurring line item on the calendar.
Why We Install James Hardie Fiber Cement Instead
We switched to installing exclusively James Hardie fiber cement siding because it holds up to this specific climate without asking homeowners to maintain a refinishing schedule to keep it protected. It's non-combustible, it's engineered specifically for wet climates through Hardie's HZ10 product line, and it comes with a factory-applied ColorPlus finish that's baked on and warrantied — not something a crew brushes on and hopes holds up through the next wet season.
Fiber cement doesn't absorb water the way wood does, so it isn't feeding moss the way exposed wood grain can, and it isn't vulnerable to the same rot pathway if a joint gets damp. It holds paint and color far longer than wood siding does in this environment, and Hardie backs it with a strong transferable warranty that reflects real confidence in how the product performs over decades, not just years.
We're not going to tell a homeowner that cedar is a bad product — it isn't. It's a wood product being asked to perform in one of the tougher climates on the West Coast for wood siding, and that's a mismatch we'd rather be upfront about than sell around. That's the whole reason we standardized on Hardie: it's the material that lets us tell a Birch Bay homeowner "this will still look right in fifteen years" and actually mean it.
