Why Color Choice Matters More Here Than Most Places
Picking a siding color sounds like the fun part of a project, and it is. But in Semiahmoo, sitting right on the water in Whatcom County, color choice isn't just about curb appeal. Salt air, driving rain off the Strait, and a long moss season put more stress on exterior paint than almost anywhere else in the state. A color that looks great on a sample chip can chalk, fade unevenly, or start peeling within a few years if the finish underneath it can't handle the exposure. That's the real reason ColorPlus technology exists, and it's worth understanding before you pick a swatch.

What ColorPlus Actually Is
ColorPlus is James Hardie's factory-applied finish system. Instead of the color being brushed or sprayed on-site after installation, each plank or panel goes through multiple coats baked on under controlled conditions at the factory, then cured before it ever reaches a job site. That process matters for a few practical reasons:
- Even coverage. No hand-painted sections, no lap marks, no thin spots where a painter rushed a corner.
- Stronger bond to the substrate. Factory curing adheres the finish to the fiber cement more consistently than field-applied paint can.
- Built-in UV and moisture resistance. The finish is formulated specifically for exterior fiber cement, not a general-purpose exterior paint pulled off a hardware store shelf.
For a home exposed to salt-laden wind and near-constant damp off the water, that consistency is the difference between a repaint every five to seven years and going a decade or more before the color needs any attention.
How the Color Lines Are Organized
James Hardie offers ColorPlus in curated palettes rather than an unlimited custom-match system, and that's intentional. The colors are selected to work well with fiber cement's texture and to perform well outdoors long-term, not just to look good on a screen. Within those palettes you'll typically find:
- Neutral and muted tones — grays, warm whites, greiges — that read well against the Pacific Northwest's grey-sky days and green surroundings.
- Deeper, richer colors — navy, charcoal, forest green — for homes that want more contrast against trim and stone.
- Traditional coastal whites and creams that hold up visually against the kind of low winter light common around Semiahmoo.
Trim, fascia, and accent pieces are available in coordinating ColorPlus finishes as well, so the whole exterior system — not just the field siding — gets the same factory-cured protection.
Choosing a Color That Works With Your Site
A few practical things worth thinking through before settling on a color:
- Sun and shade exposure. A wall that gets hit with direct afternoon sun will show fading differently than a shaded north face, even with the same product. Ask to see samples in the actual light your home gets.
- Moss and algae tendency. Darker colors can make early moss growth less visually obvious for a while, but they don't stop it. Given how much moss pressure this area sees, gutter maintenance and roof-line drainage matter more than color choice for keeping growth in check.
- Neighborhood and HOA context. Many streets near the water have an established look — worth a glance at what's around you before locking in something dramatically different.
- Trim contrast. High-contrast trim reads well in overcast climates like ours; it keeps a home from looking flat under grey skies, which is most of the year here.
What the Warranty Covers
ColorPlus finishes carry their own finish warranty, separate from the substrate warranty on the fiber cement itself, and it's transferable if you sell the home within the coverage period. That's a meaningful detail for resale — a documented, factory-backed finish warranty is a straightforward thing to hand off to a buyer, versus explaining a field-applied paint job with no manufacturer backing behind the color.
Why We Only Install ColorPlus, Not Field-Painted Options
James Hardie siding can be special-ordered primed instead of factory-finished, with paint applied after installation. We don't do that. Field-applied paint on fiber cement depends entirely on weather conditions during application, the skill and product choice of whoever's painting, and proper cure time before the next rain — none of which are things we can guarantee hold up the way a factory process does. In a climate that gives you a narrow dry window and a lot of damp months, that's too much risk to build into a siding job that's supposed to last decades. ColorPlus removes that variable entirely, which is exactly why we spec it standard on every install.
