Bellingham Cedar Looks Beautiful on Day One. The Question Is Day 3,000.
Cedar siding has a real pull. It's a genuine Pacific Northwest material, it smells right, it ages with character, and when it's freshly finished it's hard to beat for warmth and depth of grain. We understand why homeowners in Bellingham ask about it. But we don't install it, and we think you deserve the honest reasons why — not a sales pitch against it, just a straight look at what owning cedar siding actually involves once it's on your house.
What Cedar Gets Right
Cedar is a natural, renewable material with genuinely good insulating properties for a wood product, and its cellular structure has some natural resistance to decay and insects compared to other softwoods. It takes stain well, and a well-installed cedar rainscreen system can perform reasonably if the homeowner is committed to the upkeep schedule. None of that is in dispute. The issue isn't the tree — it's what happens to that wood once it's nailed to a wall in Whatcom County and left to face the weather for the next twenty years.
The Maintenance Truth
Cedar siding is not a "finish it once and forget it" product. It's a wood product that needs an ongoing maintenance relationship with its owner, and Bellingham's climate is not a gentle place to have that relationship.
- Refinishing on a real clock. Even a high-quality semi-transparent or solid stain typically needs recoating every 3-5 years, and that clock runs faster on south and west-facing walls that take direct sun and driving rain off the Sound. Skip a cycle and the wood starts absorbing moisture unevenly, which is when the real problems start.
- Moss and mildew are a standing appointment, not a one-time job. Bellingham's long wet season and moderate temperatures are close to ideal growing conditions for moss, algae, and mildew on wood siding. On many homes here, that means a deliberate wash-and-treat cycle at least once a year on top of the refinishing schedule — not just for looks, but because organic growth holds moisture against the wood.
- Salt air adds its own wear. Homes closer to Bellingham Bay and the water deal with airborne salt that accelerates finish breakdown and can work into checking and cracks in the wood grain over time, on top of the normal UV and rain exposure inland homes already face.
- Moisture behavior at the boards themselves. Cedar moves with humidity — it swells and shrinks across seasons. Combined with driving rain, that movement is what eventually opens up cupping, checking, and small cracks in individual boards, especially at butt joints and anywhere caulking has started to fail.
- Board-by-board repair, not a system fix. When a section of cedar does fail, you're usually replacing individual boards, sourcing matching stock, and refinishing the patch so it blends — a slower and more detail-sensitive repair than swapping a factory-finished panel.
What This Actually Costs Over Time
None of these tasks are expensive in isolation. The problem is that they don't stop. A cedar exterior in this climate asks for a wash-and-inspect pass most years, a full refinish every few years, and vigilant caulk and trim maintenance in between — indefinitely, for as long as you own the house. Homeowners who go in expecting a "stain it every decade" product are often surprised by how much closer to "every few years, without fail" the real schedule is once moss season and salt air are part of the equation.
Why We Install James Hardie Instead
We made a decision as a company to stop installing wood siding products, cedar included, and to build our business exclusively around James Hardie fiber cement. That's not because cedar is a bad material — it's because we got tired of watching homeowners take on a maintenance burden they didn't fully understand at the time of installation, in a climate that is unusually hard on wood siding.
James Hardie fiber cement is engineered to hold up to the exact conditions that wear cedar down. It's non-combustible, it doesn't feed moss and mildew the way wood does, and it holds its shape through wet-dry cycles instead of swelling and checking. Hardie's ColorPlus factory-applied finish is baked on under controlled conditions and backed by a real finish warranty, so you're not on a personal refinishing schedule to protect the substrate underneath. Hardie also engineers specific product lines (HZ5 and HZ10) for regions with heavy moisture exposure, which fits Bellingham and the rest of Whatcom County far better than a one-size-fits-all wood product does.
That doesn't mean Hardie is maintenance-free forever — no exterior product is. But the maintenance it does need is dramatically lighter than cedar's: periodic washing and normal caulk upkeep, not a recurring refinishing cycle tied to sun exposure and salt air.
Our Advice If You're Weighing Cedar
If you love the look of cedar and you're genuinely prepared to stay on top of refinishing and moss control indefinitely, that's a legitimate choice — it's your home. Our job is just to make sure you're deciding with the real maintenance picture in front of you, not the showroom picture. For most homeowners we talk to in this area, once they hear the actual schedule involved, factory-finished fiber cement starts to look like the lower-stress, lower-lifetime-cost option — which is exactly why it's the only siding we put on houses.
If you're deciding between cedar and fiber cement for a home in Bellingham or elsewhere in Whatcom County, we're happy to walk your specific house with you and talk through what each option would actually mean for your maintenance calendar.
