Ferndale Exterior Cedar Has a Real Case For It
Before explaining why Ferndale Exterior Co doesn't install cedar siding, it's worth being straight about why homeowners want it in the first place. Cedar is a genuinely good-looking material. It has natural grain variation, it takes stain beautifully, and it ages into a warm, textured look that manufactured products spend a lot of marketing budget trying to imitate. Western red cedar is also regionally appropriate in a historical sense — it grew here, it was milled here, and a lot of older homes in Whatcom County still wear it well after decades. None of that is in dispute.
The problem isn't the wood. The problem is what the wood needs from the homeowner, year after year, to keep looking and performing the way it did on day one — and what happens when that upkeep gets skipped, deferred, or done halfway. That's the part sales conversations tend to gloss over, and it's the part we think matters most once the crew leaves and the invoice is paid.
The Ferndale Climate Problem, Specifically
Cedar siding's weaknesses aren't abstract — they're tied directly to conditions Whatcom County throws at a house all year. Ferndale sits close enough to the Salish Sea that salt-laden air reaches exterior surfaces regularly, and that salt air accelerates the breakdown of exterior stains and finishes faster than it would inland. Add in driving rain that comes sideways off marine storms, and cedar's end grain and lap joints are constantly exposed to wind-driven moisture rather than just falling rain that sheds off a wall.
Then there's the moss and algae season, which around here isn't really a season — it's most of the year. Cool, damp, shaded conditions are exactly what moss, mold, and mildew need to colonize a wood surface, and cedar's porous structure gives organic growth something to hold onto. A north-facing wall under a fir canopy in Ferndale can show green and black staining within a year or two of a fresh stain job if it isn't actively managed.
None of this means cedar "fails." It means cedar requires a maintenance relationship with the homeowner that a lot of buyers don't fully understand until they're three years in.
What Cedar Maintenance Actually Involves
This is the part we walk clients through directly, because it's the actual cost of cedar siding — not the install price, but the decade-over-decade upkeep price.
Refinishing on a Real Clock
Semi-transparent stains on cedar typically need reapplication every 2-4 years in a marine climate like ours; solid-body stains and paints can stretch that to 5-7 years, but even those need washing, inspection, and touch-up well before that. Skip a cycle and you're not just refinishing — you're often sanding back failed coating and dealing with UV-greyed or moisture-swollen wood underneath.
Washing and Moss Control
Because of the moss and algae pressure here, cedar generally needs an annual or biannual soft wash with an appropriate cleaner, not just a garden hose rinse. Pressure washing has to be done carefully — too much pressure strips the finish and drives water into the grain, which creates the exact moisture problem you're trying to avoid.
Caulking, Fasteners, and Joints
Lap joints, butt joints, and trim intersections need periodic recaulking and inspection. Cedar moves seasonally with humidity, and that movement opens gaps that need to be caught before water gets behind the board.
Watching for Rot, Not Just Color
Fading and graying are cosmetic. Soft spots, delamination at butt joints, and swelling near the bottom courses are structural warnings — and by the time they're visible from the ground, there's often more damage on the back side of the board or in the sheathing behind it.
Cedar Upkeep at a Glance
| Task | Typical Interval | What Happens If Skipped |
|---|---|---|
| Restain / recoat | 2-4 years (semi-transparent), 5-7 years (solid/paint) | Finish fails, UV and moisture reach bare wood |
| Soft wash / moss treatment | 1-2 years | Organic growth holds moisture against the wood |
| Caulk and joint inspection | 1-2 years | Water tracks behind boards at seams |
| Full visual inspection for rot | Annually | Hidden decay spreads before it's visible |
Where the Cost Actually Lands
Cedar siding is often priced competitively at install, sometimes even below fiber cement depending on grade and sourcing. The real cost shows up over the ownership period, in labor and materials for refinishing, washing, and repair — plus the risk cost if maintenance gets deferred and moisture damage sets in behind the siding. We're not going to invent a dollar figure here because it varies too much by house, grade of cedar, and how diligent the maintenance schedule actually is. What we will say is that the total cost of ownership for cedar in a wet marine climate is materially higher than the install price alone suggests, and it's a recurring cost that doesn't stop.
That's a legitimate choice for a homeowner who wants that specific look and is willing to stay on top of it — some are, and cedar can serve them well. It's just not a maintenance schedule we're willing to sell someone into without being upfront about it first.
Why We Don't Install It
As an installer, we have to stand behind what we put on a house, and warranty language matters here. Cedar siding warranties, where they exist at all, are typically tied to the finish product (the stain or coating manufacturer) rather than the wood itself, and they generally require documented maintenance on schedule to remain valid. That puts the homeowner in the position of tracking and proving upkeep to protect a warranty that's narrower than most people assume going in.
We made a decision as a company to install products where the warranty coverage, the maintenance burden, and the real-world performance in this climate line up in the homeowner's favor without asking them to become a part-time finish carpenter. Cedar doesn't clear that bar for us, even though we respect what it offers aesthetically.
What We Install Instead: James Hardie Fiber Cement
James Hardie fiber cement is what we put on homes in Ferndale, and the reasoning ties directly back to the same climate factors that make cedar demanding.
- Non-combustible core — fiber cement doesn't feed a fire the way wood siding can, which matters as regional wildfire risk gets more attention even in wetter counties.
- ColorPlus factory finish — the color is baked on in a controlled factory process, not brushed on in the field, and it's engineered to resist the fading and peeling that field-applied stains struggle with under UV and salt air.
- HZ5 climate-engineered formulation — Hardie's HZ product line is engineered for wet, moisture-heavy climates, addressing the same driving-rain and humidity exposure that's hard on cedar.
- Moss and mildew resistance — fiber cement's composition doesn't feed organic growth the way wood grain does, which matters directly for our moss season.
- Dimensional stability — it doesn't swell, cup, or split with seasonal moisture changes the way wood can, so joints and caulk lines stay tighter for longer.
- Strong transferable warranty — coverage that's straightforward and follows the house through a sale, without requiring homeowners to log a refinishing schedule to stay protected.
It also still delivers real design range — lap profiles, shingle-style panels, and a range of factory colors and textures — so homeowners aren't choosing Hardie purely on maintenance logic and giving up curb appeal. When it's installed correctly, to Hardie's specifications for flashing, clearances, and fastening, it's a system that's built to perform in exactly the conditions Ferndale sees most: salt air, driving rain, and a long wet season that doesn't give a wood finish much time to fully dry between soakings.
A Straightforward Comparison
| Factor | Cedar Siding | James Hardie Fiber Cement |
|---|---|---|
| Refinishing needed | Every 2-7 years depending on finish type | ColorPlus finish, no field refinishing for many years |
| Moss/algae resistance | Porous, susceptible without regular washing | Resistant composition, lower maintenance need |
| Moisture-driven movement | Swells, cups, opens joints seasonally | Dimensionally stable |
| Combustibility | Combustible | Non-combustible core |
| Warranty structure | Often tied to finish, maintenance-dependent | Strong transferable product warranty |
If You Already Have Cedar Siding
If your Ferndale home currently has cedar siding and it's being maintained on schedule, there's no reason to panic or replace it early — well-maintained cedar can last a long time. The decision point usually comes when you're facing a refinish cycle that's going to be expensive anyway, or when you're already seeing joint failure, soft spots, or repeated moss staining that keeps coming back no matter how often it's washed. That's typically when it makes sense to compare the cost of another cedar refinish cycle against a one-time transition to a lower-maintenance system.
Some practical signs it's worth getting a professional opinion:
- Finish is failing in under 2-3 years despite proper application
- Boards show cupping, splitting, or soft spots at butt joints
- Moss or black staining returns within months of cleaning
- Caulk joints are cracking or separating repeatedly
- You're spending real money on refinishing every few years and want to see what the alternative actually costs
Our Honest Bottom Line
Cedar isn't a bad product — it's a high-maintenance one, and in a climate with this much salt air, driving rain, and moss pressure, that maintenance burden is heavier than in a lot of other parts of the country. We'd rather tell you that plainly up front than install something we know is going to demand a maintenance schedule most homeowners underestimate. James Hardie fiber cement is what we've standardized on because it holds up to this specific climate with a lot less asked of the homeowner over time.
If you're weighing cedar against fiber cement for your Ferndale home, we're happy to walk the property with you, look at your exposure and shading, and give you a straight answer — including a free, no-pressure estimate for what a James Hardie installation would look like on your house.
