Lynden Siding Cedar siding has a following for good reason. It's a real wood product with genuine grain, it takes stain beautifully, and on the right house it has a warmth that manufactured products spend a lot of marketing budget trying to imitate. If a homeowner in Lynden asks us about cedar, we don't try to talk them out of liking it. We just want them to understand what owning it actually involves before they commit, because the honest answer is that cedar is a maintenance relationship, not a one-time purchase.
What cedar gets right
Western red cedar is naturally resistant to decay and insects compared to most softwoods, thanks to oils in the wood itself. It's lightweight, easy to mill into different profiles, and it ages with character rather than looking simply worn out. For homeowners who want an authentic wood exterior and are willing to stay on top of it, cedar can look excellent for decades.
Where the honest trade-offs start
The word doing the heavy lifting in that last sentence is "willing." Cedar's natural resistance slows decay — it doesn't stop it. Once the factory or field-applied finish starts to break down, the wood underneath is exposed to whatever the weather throws at it, and in Whatcom County that's not a light schedule. Between driving rain off the Strait and Puget Sound, salt-laden air working its way inland, and a moss season that can run most of the year in the shade of a north-facing wall, cedar here needs more attention than the same board would in a drier climate.
- Refinishing on a clock: Semi-transparent stains typically need reapplication every 2-4 years, and solid-body finishes every 5-7, depending on sun and rain exposure. Skip a cycle and the wood starts graying and checking, which accelerates moisture entry.
- Moisture is the real enemy: Cedar moves with humidity, and in a wet Pacific Northwest winter followed by a dry summer, that expansion and contraction opens up joints, loosens fasteners, and stresses caulked seams over time.
- Moss and mildew: Shaded, north- and west-facing walls in Lynden hold moisture longer than open, sun-exposed elevations. Cedar's texture gives moss and mildew something to grip, and left alone it traps additional moisture against the board.
- Insect and rot risk at failure points: Cedar's natural resistance is strongest in heartwood. Cut ends, fastener penetrations, and any spot where the finish has failed are where carpenter ants, rot, and woodpeckers tend to find an opening.
- Combustibility: It's still wood. In wildfire-adjacent conversations across the Pacific Northwest, that's become a real consideration for insurers and homeowners alike.
What that adds up to over time
None of this means cedar "fails." Plenty of well-maintained cedar homes in this region look great after 20-plus years. But that outcome depends on a homeowner staying on a refinishing schedule, budgeting for it, and catching moisture problems early — which in practice means periodic inspection, cleaning, re-caulking, and repainting or re-staining for as long as the siding is on the house. It's a legitimate way to own an exterior. It's just a very different commitment than a homeowner who wants to install siding once and not think about it again for a long time.
Why we standardized on James Hardie instead
We made a decision as a company not to install cedar, LP SmartSide, vinyl, or a handful of other fiber cement alternatives — not because those products have no merit, but because we wanted to stand behind one system that performs consistently in this climate without asking homeowners to manage a recurring maintenance schedule just to keep moisture out.
James Hardie fiber cement is engineered specifically for wet, high-moisture climates through its HZ5 product line, which is built for exactly the conditions Whatcom County sees — sustained rain, humidity, and coastal air. The ColorPlus factory finish is baked on under controlled conditions rather than field-applied, which means significantly better fade and moisture resistance than a site-applied stain, and it doesn't require repainting on a 2-to-5-year cycle. Hardie board is also non-combustible, which matters more every year in this region, and it carries a strong transferable warranty when installed to Hardie's spec — something we take seriously because improper installation is where most fiber cement problems actually originate, not the material itself.
We're not going to tell a homeowner that cedar is a bad product. It isn't. But if the goal is a beautiful exterior that doesn't come with a standing to-do list, Hardie is what we've chosen to put our name behind, and it's what we install on every siding replacement we take on.
