Blaine Siding Cedar Has Real Appeal — and Real Demands
Cedar siding has a look that's hard to argue with. The grain, the warmth, the way it weathers — a lot of homeowners in Blaine fall in love with it before they've priced out what it actually takes to keep it looking that way. We get it. But as a siding contractor working in Whatcom County's coastal climate, we've watched enough cedar jobs age over 10, 15, 20 years to be honest with you about what ownership really involves. This page is about that honesty, not about talking cedar down.
What Cedar Gets Right
Cedar is a genuinely good wood for exterior use. It has natural oils that resist decay and insects better than most softwoods, it's lightweight and easy to mill into different profiles, and it takes stain or paint well when it's properly prepped. Old-growth cedar siding on well-maintained homes has lasted decades. None of that is in dispute.
Where the Trade-Offs Start
The catch is what "well-maintained" actually means in a place like Blaine. This is a marine-influenced climate — salt air off the Strait of Georgia and Semiahmoo Bay, driving rain that comes in sideways during winter storms, and a moss and lichen season that can run most of the year in shaded, north-facing areas. Wood siding sits at the center of all three of those pressures at once, and it needs consistent attention to hold up.
- Refinishing cycle: Stain or paint on cedar typically needs renewal every 3-7 years depending on exposure, sun, and product quality. South and west-facing walls fade and check faster; shaded north walls stay damp longer and grow moss and algae faster. Either way, you're budgeting for a recurring project, not a one-time finish.
- Salt air acceleration: Coastal salt air breaks down finishes faster than inland climates and can drive moisture into end grain and fastener holes, which is where cedar rot usually starts.
- Moss and biological growth: Whatcom County's damp, mild winters are ideal conditions for moss, mildew, and algae on wood surfaces that don't get much direct sun. Left alone, that growth holds moisture against the wood and shortens the life of both the finish and the board underneath.
- Caulking and joint maintenance: Board joints, corners, and trim intersections need to be inspected and re-caulked periodically. Once a joint opens up and driving rain gets behind the siding, you're dealing with hidden moisture damage that's expensive to find and fix.
- Insects and woodpeckers: Cedar is more insect-resistant than many woods, but it isn't immune, and it's still a preferred nesting target for woodpeckers, especially where boards have started to soften.
The Honest Cost Picture
None of this makes cedar a bad product. It makes it a higher-maintenance one, and the real cost of cedar siding isn't just the install — it's the recurring refinishing, cleaning, and repair work over the life of the home. Homeowners who go into cedar ownership expecting a "stain it once and forget it" product are usually the ones who end up frustrated a few years in, watching a south wall fade while a north wall grows moss.
| Maintenance Task | Typical Frequency in This Climate |
|---|---|
| Refinish/restain | Every 3-7 years |
| Wash to remove moss/algae | Annually, more on shaded walls |
| Caulk/joint inspection | Annually |
| Spot repair of soft or rotted boards | As needed, increasing with age |
Why We Standardized on James Hardie Instead
We made a decision as a company to install only James Hardie fiber cement siding, and cedar's maintenance burden is a big part of why. Hardie is engineered specifically for climates like ours — the HZ5 product line is formulated for the Pacific Northwest's wet, moderate weather, and it holds up to driving rain and salt-influenced air without the moisture sensitivity that wood carries. It's non-combustible, which matters more every fire season, and it won't rot, and moss and algae don't get the same foothold on it that they do on bare or lightly finished wood.
The factory-applied ColorPlus finish is the other half of the equation. Instead of a site-applied stain that starts breaking down within a few years, Hardie boards come with a baked-on finish backed by its own warranty, so you're not standing on a ladder every few seasons deciding whether this is the year you finally get around to it. Combined with Hardie's transferable warranty, it's a product built for people who want their siding to look good for decades with inspection and basic upkeep — not a recurring refinishing schedule.
We're not going to tell you cedar is a bad choice for every homeowner. Some people genuinely enjoy the upkeep and want that specific look enough to commit to it. But if you're weighing cedar against the honest, ongoing cost of owning it in a Whatcom County coastal climate, we think it's worth understanding that cost before you commit — and it's why fiber cement is what we put on homes in Blaine.
