Anacortes Siding Primed wood siding — usually finger-jointed or clear spruce, sometimes cedar — shows up on a lot of remodel proposals because it's familiar, it's paintable in any color, and it has that traditional look a lot of Anacortes homeowners want. We get asked about it regularly, and we're upfront about why we don't install it: not because it's a bad piece of lumber, but because of what happens to it once it's on a wall in Skagit County.
What primed wood siding gets right
Primed spruce and cedar lap siding have real advantages on paper. Wood is easy to cut and fit on-site, it takes paint well, and it gives a builder a lot of flexibility with reveal size and profile. For a dry inland climate with moderate humidity, a well-maintained wood siding job can look good for a long time. It's also a familiar product — most painters and carpenters have worked with it for decades, so labor isn't hard to find.
Where it runs into trouble here
The problem isn't the wood itself — it's what Anacortes and the rest of Skagit County throw at it. We're a peninsula town surrounded by saltwater on three sides, which means salt-laden air is a constant, not an occasional event. Add driving winter rain off Rosario Strait and Guemes Channel, plus a moss and algae season that can run eight or nine months out of the year in the shade of a Douglas fir canopy, and you've got a siding material that's under near-constant moisture and biological pressure.
Primed wood is exactly what it sounds like: raw wood with a factory or job-site primer coat, not a fully cured finish. That primer is a base layer, not a shield. Once it's installed, the field-applied topcoat is doing all the real protective work, and that topcoat is only as good as the weather conditions it was applied in, the number of coats, and how quickly it went on after the primer was exposed to the elements. In a marine climate where dry install windows are limited, that's a lot of variables working against the homeowner.
The maintenance cycle is the real cost
- Repainting on a clock: Wood siding in our climate typically needs repainting every 3-7 years depending on exposure, sun, and how well the first job was done. South and west-facing walls that catch driving rain wear fastest.
- End grain and joints are the weak point: Butt joints, corners, and cut ends are where paint fails first and where moisture gets behind the material. Once water gets in, it doesn't dry out quickly in our humidity.
- Moss and mildew growth: Shaded elevations and north walls stay damp longer here than almost anywhere else in the state, which accelerates surface breakdown and paint failure, and invites the kind of soft, spongy wood that's expensive to catch late.
- Caulk and touch-up cycles: Between full repaints, wood siding usually needs caulking and spot maintenance to stay watertight, which is easy to defer and easy to forget until there's a problem behind the wall.
Why we don't put our name on it
We install exteriors that are meant to last, and we don't want a callback five years from now because a coastal storm season did what coastal storm seasons do to painted wood. Every wood siding job we'd install here would come with an honest disclaimer: this will need real maintenance on a schedule, and if that maintenance slips, moisture damage follows. That's a legitimate choice for some homeowners who want the traditional wood look and are willing to stay on top of it. It's just not a standard we're willing to build our installation business on, especially in a climate this hard on painted wood.
What we install instead
Every home we side gets James Hardie fiber cement. It's not a wood substitute in the sense of being "close enough" — it's a fundamentally different material. Hardie board is cement, sand, and cellulose fiber, so it doesn't absorb moisture the way wood does, it won't feed moss and mildew the way bare wood can, and it's non-combustible, which matters given how many Anacortes properties border dry brush and treed lots.
The bigger difference is the finish. Hardie's ColorPlus technology is a factory-applied, baked-on finish, not a field-applied primer and topcoat. It's cured under controlled conditions before it ever leaves the plant, so you're not depending on a dry stretch of Pacific Northwest weather to get full paint adhesion. Hardie also engineers specific product lines (HZ5) for climates like ours — places with real humidity, rain, and freeze-thaw swings — rather than a one-size-fits-all board. That climate-specific engineering, backed by a strong transferable warranty, is the difference between siding that needs a maintenance plan and siding that mostly just needs an occasional rinse.
The honest comparison
| Factor | Primed Wood Siding | James Hardie Fiber Cement |
|---|---|---|
| Finish durability | Field-applied, weather-dependent | Factory-baked ColorPlus finish |
| Repaint cycle | Roughly every 3-7 years here | Typically 15+ years before repaint |
| Moisture/moss resistance | Vulnerable, especially at joints and shaded walls | Engineered for high-moisture climates |
| Fire rating | Combustible | Non-combustible |
| Warranty | Varies by paint/labor, not the material | Strong manufacturer warranty, transferable |
