Lynden One Product Line, On Purpose
We get asked fairly often why we don't offer a menu of siding options. Homeowners are used to contractors who'll install whatever brand they bring in. We made a different call a while back: James Hardie fiber cement is the only siding we put on houses in Lynden and the rest of Whatcom County. This page explains the reasoning, not just the marketing.
What Lynden's Climate Actually Does to a Wall
Lynden sits close enough to the Salish Sea and the Nooksack lowlands that homes deal with a specific combination of stresses: salt-tinged air moving in off the Strait, long stretches of driving rain in fall and winter, and a moss season that can run eight or nine months if a wall stays damp and shaded. Siding here isn't just cladding — it's a barrier that has to shed water for decades without cupping, rotting, or feeding organic growth. Some products handle that combination well. Others handle it in theory, under ideal installation and maintenance, which in the real world doesn't always happen.
Why Fiber Cement, Specifically
James Hardie siding is cement, sand, and cellulose fiber, cured into a dense, dimensionally stable board. It doesn't absorb water the way wood-based products can, it won't ignite, and it doesn't expand and contract with humidity swings the way engineered wood or untreated wood siding does. For a region with our rain totals and moss pressure, that stability matters more than it does in a dry climate.
Climate-Engineered Product Lines
Hardie doesn't sell one formulation nationwide. Their HZ5 and HZ10 lines are engineered for different climate zones, adjusting the product for moisture exposure and freeze-thaw behavior. Western Washington falls into the wetter end of that spectrum, and we spec accordingly. That's a level of climate-specific engineering that most alternative siding products don't offer — they're built to one national spec regardless of whether the house is in Arizona or Whatcom County.
ColorPlus Factory Finish
Most of what we install uses Hardie's ColorPlus finish — a baked-on, factory-applied topcoat rather than field-applied paint. It's more UV and moisture resistant than a site-painted finish, the color is consistent board to board, and it carries its own finish warranty separate from the substrate warranty. For homeowners tired of repainting siding every 6-8 years, this is often the single biggest reason they choose Hardie over a paint-grade alternative.
Non-Combustible
Fiber cement doesn't burn. That's not a small detail for insurance purposes or for homeowners who've thought about wildfire smoke and ember exposure in recent Pacific Northwest fire seasons. It's not the primary reason we standardized on Hardie, but it's a real, honest advantage over wood-based and some engineered wood siding products.
Warranty Structure
Hardie backs their siding with a strong, transferable limited warranty on the substrate, and ColorPlus finishes carry their own separate coverage. Transferability matters at resale — it's a warranty that follows the house, not just the original owner, which buyers and their inspectors notice.
What We're Not Saying
We're not going to tell you every other siding product on the market is junk — that's not honest, and it's not our call to make about products we don't install. Vinyl, LP SmartSide, cedar, and other fiber cement brands all have legitimate use cases and loyal installers. What we are saying is that after years of doing exterior work in this specific climate, we settled on one system that we trust enough to stand behind with our own labor warranty, and that's the only one we'll put our name on.
What Correct Installation Involves
Hardie's performance depends heavily on installation matching their published specs — this is a product that punishes shortcuts. That means:
- Correct nailing pattern and fastener type, not whatever happens to be in the gun
- Proper clearance from grade, decks, and roof lines to keep the bottom edge out of standing water
- Rain screen or drainage plane detailing appropriate for our rainfall volumes
- Caulking and flashing at every penetration, sized and placed per manufacturer detail, not general carpentry habit
- Field-cut edges properly sealed, since exposed raw fiber cement is where premature wear starts
A lot of the complaints people hear about fiber cement siding trace back to installation shortcuts, not the material itself. That's part of why we don't subcontract this out casually — the product is only as good as the crew putting it on the wall.
Colors and Profiles
Hardie's lineup covers lap siding in multiple exposures, shingle-style panels, board-and-batten, and trim in matching ColorPlus tones, which gives us enough range to match traditional Whatcom County farmhouse styles as well as newer builds without stepping outside the one product system we trust.
Bottom Line
We didn't standardize on James Hardie because it's the only decent siding made. We did it because, for this specific climate — the salt air, the rain, the moss — it's the product we're comfortable warrantying our own installation work against, year after year, on Lynden roofs and walls that take a real beating from November through March.
