Blaine Siding Two Very Different Materials, One Big Decision
Vinyl and fiber cement are the two most common siding choices homeowners in Blaine ask us about, and they get compared constantly because they sit in a similar price range for the material itself. But they are not similar products. One is an extruded plastic panel. The other is a cement-based board engineered to behave like wood without wood's weaknesses. Once you understand how each one is built, the trade-offs become a lot clearer.
We want to be upfront about our position: we install James Hardie fiber cement siding exclusively. We don't install vinyl. This page isn't here to trash vinyl siding — it's a legitimate, widely used product with real advantages. It's here to explain, honestly, why we made the call we did and what that means for a house in this part of Whatcom County.
What Vinyl Does Well
Vinyl siding earned its popularity for good reasons. It's inexpensive, lightweight, and fast to install. It never needs painting, it resists minor dents better than people expect, and for a homeowner on a tight budget it can be a reasonable way to get a fresh exterior. In dry, moderate climates, vinyl can perform for decades with little complaint.
Where it struggles is in the details that matter most on the Blaine peninsula: salt air off the Strait of Georgia, wind-driven rain that comes in sideways off the water, and a moss season that stretches long into the year under our cloud cover.
Where Vinyl Runs Into Trouble Here
- Heat and cold movement: Vinyl expands and contracts significantly with temperature swings. Panels are hung loosely by design to allow for this, which means seams, waves, and buckling become more visible over time, especially on south- and west-facing walls.
- It's not waterproof, it's water-managed: Vinyl relies on lapped panels and a drainage plane behind it to shed water. In steady, driving coastal rain, wind can force moisture behind panels at seams, corners, and fastener points. The siding itself survives; the problem shows up later in the sheathing behind it.
- UV and salt exposure fade color: Vinyl's color is mixed through the plastic, but constant UV and salt air still cause noticeable fading and chalking over the years, and unlike paint, faded vinyl can't be touched up — the whole panel has to be replaced to match.
- Moss and organic growth: Vinyl's textured surface and the shaded, damp wall sections common on wooded Blaine lots give moss and algae a place to grab hold. It's a cosmetic issue, not a structural one, but it means regular washing to keep the house looking cared for.
- Impact damage: A hard hit — a wind-thrown branch, a ladder, a stray baseball — can crack or shatter a vinyl panel outright, and replacement pieces can be hard to color-match years later.
What Fiber Cement Changes
James Hardie siding is made from cement, sand, and cellulose fiber, pressed and cured into a board that doesn't expand and contract the way vinyl does, doesn't burn, and doesn't feed moss and mildew the way wood-based products can. It's heavier and more labor-intensive to install correctly, which is part of why it costs more up front. But the properties that matter in a coastal, wet climate are baked into the material itself.
Hardie's HZ5 product line is specifically engineered for climates with harsh weather exposure, including moisture and freeze-thaw cycling — a real consideration during Whatcom County's cold snaps. The ColorPlus factory finish is baked on under controlled conditions, which holds color far more consistently against UV and salt air than field-applied paint, and it comes backed by a stronger, transferable warranty than what vinyl manufacturers typically offer.
A Side-by-Side Look
| Factor | Vinyl | Fiber Cement (James Hardie) |
|---|---|---|
| Upfront material cost | Lower | Higher |
| Fire resistance | Combustible | Non-combustible |
| Expansion/contraction | Significant | Minimal |
| Impact resistance | Can crack/shatter | Resists denting and cracking |
| Color retention | Fades, chalks over time | Factory finish holds color longer |
| Moisture behavior in driving rain | Relies on drainage plane | Rigid board, engineered for wet climates |
| Typical warranty | Varies, often prorated | Longer, transferable |
Why We Standardized on One Product
We don't install vinyl, LP SmartSide, or unfinished wood siding — not because those products don't have a place somewhere, but because after years of exterior work around Blaine, Birch Bay, and the rest of Whatcom County, we saw the same pattern: salt air, moss season, and driving rain expose the weak points of lighter, less rigid materials faster than they do in drier parts of the state. Standardizing on James Hardie lets us install one system we know inside and out, back it with a warranty we trust, and stop guessing which product will actually hold up on a given lot.
That's the honest version. Vinyl isn't a bad product — it's just not the one we're willing to put our name behind on this stretch of coastline.
Thinking It Through for Your Home
The right siding choice depends on your budget, how long you plan to stay in the house, and how much maintenance you want to deal with over the next twenty years.
