Chuckanut Exterior An Honest Look at Vinyl Siding
Vinyl siding didn't become the most common siding material in America by accident. It's inexpensive, it goes up fast, it never needs painting, and for a lot of homes in drier, milder climates it does its job for decades without much fuss. If a homeowner in Chuckanut asks us to bid a vinyl job, we're not going to pretend the product is junk — it isn't. We're going to tell them why we, as a company, chose not to install it, and let them decide for themselves with the full picture in front of them.
That's the purpose of this page. Not to trash vinyl siding, but to explain the trade-offs that led Chuckanut Exterior Companies to standardize on one product — James Hardie fiber cement — and walk away from vinyl, LP SmartSide, and a handful of other common materials.
What Vinyl Gets Right
Credit where it's due:
- Upfront cost. Vinyl is almost always the cheapest siding option per square foot, both in material and labor.
- No painting. The color is baked into the material, so there's no repaint cycle the way there is with wood or primed products.
- Fast installation. Panels are light, they snap into place quickly, and a crew can close in a house in a fraction of the time fiber cement takes.
- Won't rot. It's plastic — it doesn't absorb water into the material itself the way wood does.
For a lot of markets, that's a perfectly reasonable set of trade-offs. Chuckanut's climate is where those trade-offs start to work against the homeowner.
Why Our Local Climate Changes the Math
Salt air
Whatcom County's coastal exposure means homes here deal with salt-laden air more than most inland Washington markets. Salt accelerates the breakdown of the plasticizers that keep vinyl flexible, and it's part of what drives the chalky, faded look you see on older vinyl homes near the water years before you'd expect it based on the manufacturer's warranty numbers.
Driving rain
Vinyl siding is not a waterproof cladding — it's designed as a rain screen, meaning it sheds most water but relies on the water-resistive barrier and flashing underneath to handle what gets through the seams, laps, and penetrations. In a climate with frequent wind-driven rain, more water gets pushed behind the panels than in calmer regions, which puts more pressure on details most crews rush: window and door flashing, inside corners, and butt joints.
A long moss season
Western Washington's extended damp season is hard on any siding, but vinyl's slightly textured surface and the shaded, north-facing walls common on wooded Chuckanut lots give moss and algae a place to take hold. Vinyl doesn't feed the growth any more than other materials do, but it also doesn't offer any factory-applied resistance to it, and the surface texture holds moisture longer than a smoother, denser material.
Installation Sensitivity Is the Real Issue
Most of vinyl's real-world problems don't come from the material failing on its own — they come from how unforgiving it is to install correctly, and how easy it is to install just well enough that it looks fine on day one.
- Nailing tolerance. Vinyl panels expand and contract significantly with temperature swings. Nails have to be driven in the center of the slot and left slightly loose so the panel can move. Over-driven nails — extremely common on production crews paid by the square — buckle, oil-can, or crack panels within a few seasons.
- Expansion gaps. Panels need gaps at corners and trim to allow for movement. Skip them, and panels bow or pop loose the first time temperatures swing.
- Housewrap and flashing quality. Because vinyl relies so heavily on what's behind it, sloppy water-resistive barrier work or flashing shortcuts don't show up as a leak for years — by which point the sheathing underneath may already be compromised.
None of this is unique to any one installer — it's inherent to the product. Fiber cement has its own installation requirements, but it's far more tolerant of minor variance and doesn't rely on precise thermal-movement gaps to perform.
What Happens Behind the Panel
Because vinyl isn't a fully sealed cladding, moisture management depends almost entirely on the layers behind it — housewrap, flashing, and proper venting. That's true of most siding systems to some degree, but it matters more with vinyl because the panel itself contributes nothing structurally and very little as a moisture barrier. In a region with as much annual rainfall as Whatcom County, we'd rather install a product that adds a genuine layer of moisture resistance on its own, not one that depends entirely on what's underneath it being perfect and staying that way for 20-plus years.
Fire and Impact Considerations
Vinyl is a petroleum-based product — it softens, warps, and can melt at temperatures well below open flame, including heat from a nearby grill, fire pit, or even reflected sunlight off certain low-E windows. It also becomes brittle in cold weather and can crack on impact from hail, thrown gravel from a mower, or accidental contact from a ladder. Fiber cement is non-combustible and holds up to impact significantly better. For homes near wooded lots — common throughout Chuckanut and greater Whatcom County — that fire performance difference is one we take seriously enough to build our entire installation business around it.
Vinyl vs. James Hardie Fiber Cement: The Honest Comparison
| Factor | Vinyl Siding | James Hardie Fiber Cement |
|---|---|---|
| Upfront cost | Lowest of common siding options | Higher material and labor cost |
| Moisture resistance | Depends on barrier/flashing behind panel | Denser material, factory-engineered moisture resistance |
| Fire performance | Combustible, softens/melts under heat | Non-combustible |
| Color/finish life | Fades and chalks over time, especially with UV and salt exposure | ColorPlus factory finish backed by its own coating warranty |
| Impact resistance | Can crack in cold, dents on impact | More resistant to impact and cold-weather brittleness |
| Installation tolerance | Requires precise nailing and expansion gaps | More forgiving, but still requires trained installation |
| Regional fit | Workable, but exposed to salt/rain/moss stress here | HZ product lines engineered for wet climate zones |
Why We Standardized on James Hardie
We made a decision early on to install one siding system and install it well, rather than offer every product a homeowner might ask for and do all of them at an average level. James Hardie fiber cement is non-combustible, it's engineered specifically for climate zones like ours through its HZ5 product lines, and the ColorPlus factory finish holds color far longer than field-applied paint or vinyl's baked-in pigment. It also carries a strong transferable warranty that reflects the manufacturer's confidence in the product when it's installed to spec — which is the other half of the equation. A great product installed poorly still fails. That's why we train our crews on Hardie's installation requirements specifically, rather than spreading that expertise thin across several different siding systems.
We don't install LP SmartSide, Cemplank, Allura, primed spruce, or cedar either, for related reasons — moisture behavior, maintenance burden, or warranty structure that didn't meet the standard we wanted to build our business on. Hardie isn't the cheapest option on the table, and we tell people that upfront. It's the one we're willing to warranty our workmanship against.
A Practical Checklist If You're Still Considering Vinyl
If cost is the deciding factor and vinyl is still on your list, these are the questions worth asking any installer:
- What gauge/thickness vinyl is being quoted, and is it rated for coastal or high-wind exposure?
- What's the housewrap and flashing detail at windows, doors, and inside corners?
- Will nails be hand-driven with proper float, or air-gunned at production speed?
- What's actually covered under the manufacturer's warranty versus the installer's labor warranty?
- How will the crew handle expansion gaps at trim, corners, and butt joints?
If a contractor can't answer those clearly, that's worth knowing before the panels go up — regardless of which material you choose.
The Bottom Line
Vinyl siding isn't a bad product; it's a product that performs best in conditions gentler than what Chuckanut and the rest of Whatcom County deal with year-round. Between the salt air, the driving rain, and a moss season that stretches for months, we'd rather put our name behind a siding system engineered for exactly this kind of exposure than one that asks a homeowner to hope the details behind it were done perfectly and stay that way for decades.
