Lynden Cedar siding has a real appeal. It's a natural material, it smells good on install day, and a freshly stained cedar home in Lynden has a warmth that manufactured products spend a lot of marketing money trying to imitate. We're not here to tell you cedar is a bad material. We're here to tell you why, as a company that has to stand behind what we put on your walls, we stopped installing it.
What Cedar Gets Right
Cedar is naturally rot-resistant compared to most softwoods, it's lightweight, it takes stain well, and it has a genuine curb appeal that some homeowners specifically want. If you love the look of real wood grain and you're prepared for what owning it involves, that preference is legitimate. Our issue isn't with the wood itself — it's with what Whatcom County weather does to it over time, and what that means for the homeowner who has to keep up with it.
The Climate Problem
Lynden sits inland from the Salish Sea, but the region still gets the marine air, the long wet season, and the low winter sun angles that keep north- and west-facing walls damp for days at a time. Add in the driving rain that blows through Whatcom County in fall and winter storms, and cedar siding is almost never given a full chance to dry out before the next system rolls through. Wood siding needs to breathe and dry between soakings. When it doesn't get that chance, moisture gets trapped in the grain, and that's where the real problems start.
Moss Season Isn't a Season Here — It's Most of the Year
Anyone who has owned a house in this part of Washington knows moss doesn't wait for winter. Shaded walls, fence lines, and roof-adjacent siding start growing moss and algae within a year or two of a fresh cedar install, sometimes faster on the north side of a house tucked under trees. Moss holds moisture directly against the wood fibers, and that constant dampness is what accelerates rot, cupping, and finish failure — long before the siding is actually "old."
The Maintenance Cedar Actually Requires
This is the part that doesn't always get explained clearly at the point of sale. Cedar siding is not a one-and-done install. To get a normal lifespan out of it, a homeowner is signing up for:
- Re-staining or re-sealing every 3 to 5 years, sooner on sun- and rain-exposed elevations
- Regular moss and algae treatment or gentle washing, especially on shaded walls
- Caulk and joint inspection every year, since wood moves seasonally and gaps let water behind the boards
- Prompt repair of any board that starts cupping, splitting, or showing soft spots — waiting turns a board repair into a sheathing repair
- Watching for woodpecker and insect activity, which cedar is not immune to
None of that is unreasonable to ask of a homeowner who wants real wood. But it's a real, recurring cost in time and money, and it's honestly more than most families sign up for when they picture "new siding" solving their maintenance headaches, not adding to them.
What Happens When Maintenance Slips
Life gets busy, and re-staining a house is not a small weekend project. When it gets pushed a year or two past due, the clear or semi-transparent finishes that show off the wood grain break down fast, and bare cedar starts absorbing water directly. Once water gets past the finish and into the wood repeatedly, you start seeing checking, cupping, and eventually soft or rotted boards — usually first at the bottom courses near grade, around window sills, and on the most weather-exposed elevation of the house. By the time it's visibly obvious, the damage is often already into the sheathing behind it, which turns a siding problem into a structural one.
The Warranty Reality
Cedar siding warranties, where they exist, are typically about material defects in the wood itself — not about weathering, finish breakdown, moss damage, or rot from moisture exposure, which are treated as normal wear and maintenance items. That's a fair way for a wood product to be warrantied. But it means the homeowner is carrying nearly all of the long-term performance risk, year after year, in a climate that doesn't do the wood any favors.
Why We Install James Hardie Instead
We standardized on James Hardie fiber cement because it holds up to this specific climate without asking the homeowner to become a part-time siding caretaker. Hardie's HZ5 product line is engineered for climates with exactly this combination of moisture, freeze-thaw swings, and sustained damp exposure. It's non-combustible, it doesn't rot, and it doesn't feed moss the same organic material that wood does. The ColorPlus factory finish is baked on under controlled conditions rather than applied on a ladder in variable weather, and it's backed by a strong transferable warranty that actually covers the finish, not just the substrate.
That doesn't mean Hardie siding needs zero attention — it still benefits from an occasional rinse and a periodic look-over like anything on the outside of a house. But it doesn't require a maintenance calendar, and it doesn't put a homeowner in a race against the next rainy season to keep the finish intact.
