Bellingham Why Cedar Gets a Second Look
Every year we get calls from homeowners in Bellingham, Fairhaven, and up the Guide Meridian corridor asking about cedar siding. It's not a mystery why. Cedar has real warmth — a natural grain, a color that ages into a handsome silver-gray if left alone, and a heritage look that fits the Pacific Northwest aesthetic better than almost anything else on the market. If you grew up around cedar-clad homes in Whatcom County, it's easy to want that look on your own house.
We're not here to talk anyone out of liking cedar. It's a legitimate, time-tested material, and there are skilled installers who do good work with it. But we made a business decision years ago to stop installing it, and we think homeowners deserve the honest reasoning behind that decision rather than a sales pitch for whatever we happen to carry. This page is that reasoning.
What Cedar Siding Actually Requires
Cedar's natural resins give it decent inherent resistance to decay and insects compared to other softwoods, which is exactly why it built its reputation over the last century. But "decent resistance" is not "maintenance-free," and that gap is where most cedar siding problems start — usually five to ten years after installation, right when a homeowner has stopped thinking about the siding at all.
The Finish Cycle
Cedar siding needs a film-forming or penetrating finish — stain, paint, or a clear sealer — to control moisture movement in and out of the wood. Left bare, cedar will gray naturally, but "graying naturally" isn't cosmetic only; it also means the wood surface is checking, cupping, and losing its ability to shed water evenly. Most manufacturers and painting contractors recommend:
- Solid-color stain or paint: recoat every 5-8 years, more often on south- and west-facing walls
- Semi-transparent stain: recoat every 3-5 years
- Clear sealers: every 2-3 years, since they offer the least UV protection
- Caulking and sealant joints inspected annually and redone every few years
That's not a one-time cost. It's a recurring line item for the life of the siding, and skipping a cycle doesn't just mean faded color — it means the wood is absorbing and releasing moisture unevenly, which is the mechanism behind almost every serious cedar failure we get called to look at.
Board Movement and Fastener Wear
Wood is hygroscopic — it swells when wet and shrinks when it dries out. Cedar does this less than most species, but it still does it, cycle after cycle, year after year. Over time this movement works fasteners loose, opens up seams and butt joints, and stresses the finish at exactly the points where water intrusion does the most damage. In a climate that swings between saturated winters and dry summer stretches, that expansion-contraction cycle runs hard.
Why Whatcom County's Climate Is Tough on Cedar Specifically
Every siding material has a climate it performs best in, and every climate has a material it's hardest on. Bellingham's climate is a demanding one for wood siding for a few specific reasons.
Salt Air Near the Water
Homes near Bellingham Bay, Chuckanut Drive, or anywhere with a marine exposure deal with salt-laden air that accelerates the breakdown of finishes and speeds corrosion of the fasteners holding the siding on. A stainless fastener helps, but the finish above it is still taking a beating faster than it would inland.
Driving Rain and Wind-Driven Moisture
Whatcom County doesn't just get a lot of rain — it gets a lot of wind-driven rain off the Strait and the Sound, which pushes water sideways into wall assemblies rather than letting it simply run down and off. That's a much harder condition for any lap siding to shed cleanly, and it's especially unforgiving of the small gaps and checks that develop in an aging cedar finish.
The Long Moss and Mildew Season
Our extended wet season, combined with mild temperatures, is close to ideal growing conditions for moss, algae, and mildew on exterior wood. Once organic growth establishes on a cedar wall — especially on north-facing or shaded elevations under trees, which describes a lot of lots in this area — it holds moisture against the wood surface for extended periods, well past what the finish was designed to tolerate. Cleaning it off without damaging the wood or the finish is its own specialized task, and it has to be repeated.
Where Failures Actually Show Up
When cedar siding does fail, it's rarely a mystery once you're standing in front of it. The common patterns we see on service calls and estimates are consistent:
- Butt joints and corner boards where end-grain is exposed and finish coverage is hardest to maintain
- Bottom courses near grade, decks, and downspout splash zones where moisture exposure is constant
- North-facing walls and shaded areas under overhangs or trees where moss and mildew take hold
- Nail heads that have worked loose or rusted through an aging finish, leaving a path for water
- Cupped or checked boards on south- and west-facing walls that took the most UV exposure
None of these are manufacturing defects. They're the predictable result of a wood product doing what wood does, in a climate that gives it plenty of opportunity to do it.
Cost Over Time: Cedar vs. James Hardie Fiber Cement
We don't invent numbers, so treat this table as a factor comparison, not a quote. The point isn't the dollar figures — it's the shape of the cost curve.
| Factor | Cedar Siding | James Hardie Fiber Cement |
|---|---|---|
| Initial material character | Natural wood grain, ages to gray if unfinished | Factory ColorPlus finish or field-painted, engineered grain textures |
| Recoat/refinish cycle | Every 3-8 years depending on finish type | ColorPlus finish is warranted for years without repainting; field paint lasts far longer than on wood |
| Moisture behavior | Absorbs and releases moisture; prone to cupping, checking, rot at exposed areas | Engineered to resist moisture-related swelling and rot when installed to spec |
| Combustibility | Combustible wood product | Non-combustible fiber cement |
| Pest vulnerability | Some natural resistance, but not immune to insects or woodpeckers | Not a food or nesting source for wood-boring insects |
| Typical warranty structure | Varies by finish applicator; wood itself carries limited manufacturer warranty | Strong transferable product warranty from the manufacturer |
Cedar's lower sticker price at installation is real. So is the recurring bill that shows up every few years afterward, and the risk that a missed maintenance cycle turns into a section of siding replacement rather than just a repaint.
The Fire Consideration
This one matters more in Washington than it used to. Wildfire smoke seasons have become a regular late-summer reality even west of the Cascades, and insurance underwriting is increasingly paying attention to home exterior materials. Cedar is a combustible wood product. James Hardie fiber cement is non-combustible. For a lot of homeowners this isn't the deciding factor on its own, but it's part of a broader risk picture — alongside maintenance burden and moisture performance — that pushed us toward standardizing on fiber cement rather than offering both.
Why We Standardized on James Hardie
We made a call, as a company, to install one exterior wall product rather than juggle several: James Hardie fiber cement, in its climate-engineered HZ product lines built for regions like ours. A few reasons that decision holds up:
- One installation standard. Our crews install one system to spec, every time, rather than switching techniques between wood, vinyl, and fiber cement — installation quality is where most siding failures actually originate, regardless of material.
- Factory-cured ColorPlus finish. The color and finish are baked on in a controlled environment rather than applied on a ladder in variable Bellingham weather, and it's built to hold up far longer between recoats than a field-applied wood stain.
- Engineered for wet marine climates. Hardie's HZ10 product line is specifically formulated for climate zones like the Pacific Northwest's, which matters when the material has to perform through our winters year after year.
- Non-combustible. One less variable in a wildfire-smoke era.
- A warranty structure that's actually transferable if you sell the home, which matters more to buyers and their inspectors than it used to.
We're not claiming fiber cement never needs any attention — no exterior product is zero-maintenance. It needs periodic washing, caulk checks, and eventually a repaint if it's not a ColorPlus finish. But the interval and the risk profile are different from wood, and that difference is the whole reason we stopped offering cedar as an option.
If You Already Have Cedar Siding
Plenty of good, well-maintained cedar homes exist around Whatcom County, and we're not suggesting every one of them needs to be torn off. If you have existing cedar and want to keep it going, a realistic self-check looks like this:
- Walk the perimeter and check butt joints, corner boards, and areas near grade for soft spots or visible checking
- Look at north-facing and shaded walls for moss or dark staining that suggests trapped moisture
- Check the finish for chalking, peeling, or bare wood exposure, especially on south and west elevations
- Note any loose or rust-streaked fastener heads
- Get a realistic timeline from whoever refinishes it on when the next recoat is actually due, not just when it "still looks okay"
When a cedar exterior reaches the point where refinishing costs start rivaling replacement, that's usually when we get the call — and that's the point where a conversation about switching to fiber cement makes practical sense rather than being a hard sell.
