Semiahmoo One Product, No Exceptions
Homeowners sometimes ask why we don't offer a menu of siding options the way some contractors do. The honest answer is that we made a business decision a long time ago to install James Hardie fiber cement siding and nothing else. Not vinyl, not LP SmartSide, not Cemplank or Allura, not primed spruce, not cedar. This page explains the reasoning, not the marketing.
What Semiahmoo's Climate Actually Does to Siding
Semiahmoo sits right on the water, which means siding here deals with more than typical Pacific Northwest rain. There's salt air working on fasteners and finishes, driving rain that gets pushed sideways into wall assemblies during winter storms, and a long moss season where shaded, north-facing walls stay damp for months at a time. Whatcom County's marine climate is not harsh in the way a hurricane zone is harsh, but it's relentless. Siding here doesn't fail from one big event — it fails slowly, from years of moisture cycling, UV, and salt exposure that most products weren't specifically engineered to handle.
That's the filter we run every siding material through: not "does it look good going up" but "what does it look like in 15 years on a lot two blocks from the water."
Why We Standardized on James Hardie
It's Fiber Cement, Not Wood or Wood-Based
James Hardie siding is made from cement, sand, and cellulose fibers, cured into a rigid board. It doesn't have the wood content that makes some engineered wood products vulnerable to swelling, delamination, or rot at cut edges and butt joints when water gets behind them. In a climate where siding stays wet for extended stretches, that matters more than it does in drier regions.
Non-Combustible
Fiber cement doesn't burn. That's a straightforward safety advantage over wood-based and vinyl products, and it's increasingly reflected in insurance considerations for homeowners.
Engineered for Specific Climates
James Hardie makes region-specific product lines, including an HZ5 line engineered for wetter, harsher climates like ours. That's not a marketing label — the formulation and moisture management are built around real regional weather data. We're not adapting a generic national product to Whatcom County; we're installing something designed with places like this in mind.
ColorPlus Factory Finish
Most of what we install uses Hardie's ColorPlus finish — a baked-on, multi-coat finish applied at the factory under controlled conditions, not painted on site. It resists fading and holds up to UV and salt air better than field-applied paint, and it carries its own finish warranty separate from the substrate warranty. For a lot on Semiahmoo Bay taking direct sun and salt spray, that finish durability is not a small detail.
A Warranty Structure That Actually Transfers
James Hardie backs its siding with a strong, transferable limited warranty. If you sell the home, that coverage doesn't evaporate — it follows the house, which matters to buyers and to resale value.
Long Track Record When Installed Correctly
Fiber cement siding has been on homes in wet climates for decades now, and the performance history is well established. The caveat — and it's a real one — is that Hardie has to be installed to spec. Clearances above grade and roof lines, correct fastening, proper flashing and water-resistive barrier detailing, and factory-cut or properly sealed field cuts all matter. Poorly installed Hardie can have problems. Correctly installed Hardie, in our experience, is about as low-maintenance as siding gets in this region.
What This Means for You as a Homeowner
- We're not going to quote you three siding options and let price alone make the decision.
- Every job we do gets Hardie's HZ5 formulation and ColorPlus finish where color-matched siding is used.
- We install to Hardie's published fastening and clearance specs, because that's what keeps the warranty valid and the product performing.
- If Hardie genuinely isn't the right fit for your project or budget, we'll tell you that directly rather than substitute a different product line.
Colors and Product Lines
James Hardie offers several siding profiles — lap siding in various exposures, panel siding, shingle-style siding, and trim boards — so the look of cedar lap, board-and-batten, or shake can be replicated without the maintenance burden of the real material. ColorPlus comes in a curated palette designed to hold up outdoors, and Hardie also offers primed product for homeowners who want to choose their own paint color, though we generally steer people toward factory-finished ColorPlus for the durability advantage.
We'd Rather Do Fewer Products Well
Specializing in one siding system means our crews aren't relearning installation quirks between materials — they know Hardie's fastening patterns, flashing details, and joint treatments cold. In a climate that punishes shortcuts, that consistency is worth more than offering variety for its own sake.
