Lynden Siding Why We Standardized on One Product
We get asked fairly often why we don't offer a menu of siding brands. The honest answer is that we used to install more than one, and the callbacks, the moisture problems, and the maintenance calls all pointed the same direction. In Whatcom County, with salt air rolling in off Puget Sound, driving rain for most of the year, and a moss season that can stretch from October into May, siding material choice isn't cosmetic. It's structural. James Hardie fiber cement is the only product we've found that holds up to this climate without asking homeowners to babysit it. So it's what we install, full stop.
What Fiber Cement Actually Does Differently
James Hardie siding is made from cement, sand, and cellulose fiber, then cured under pressure. That composition matters here for a few concrete reasons:
- It doesn't rot. Wood-based products, no matter how well treated, are organic material sitting in a wet climate. Fiber cement isn't food for anything, and it doesn't swell or delaminate when it takes on moisture the way wood-based composites can.
- It's non-combustible. That's a real consideration for insurance and for peace of mind, not just a marketing line.
- It holds paint and factory finish far longer than wood substrates. Less flexing and swelling with temperature and moisture means the finish stays put.
- It stands up to salt air. Homes closer to Drayton Harbor and the Sound take a beating from airborne salt that accelerates corrosion and finish breakdown on lesser materials. Fiber cement doesn't corrode.
The HZ5 Engineering Piece
James Hardie engineers specific product formulations for different climate zones, and that's not a gimmick — it changes how the board is manufactured. Lynden falls into what Hardie classifies as a moisture-intensive zone, and the HZ5 product line is formulated for exactly the conditions we get: sustained rain, humidity, and freeze-thaw swings in winter. Using climate-matched product isn't optional in our book. It's part of why we only install Hardie: we know exactly which formulation belongs on a house in Whatcom County, and we don't have to guess with a generic national product.
ColorPlus Finish vs. Field Painting
Every Hardie board we install can be ordered with the ColorPlus factory finish — baked on in a controlled environment, with multiple coats and a clear coat over the top. This matters more here than in drier climates for two reasons. First, field-applied paint on siding needs a stretch of dry weather to cure properly, and that window can be narrow in fall and winter here. Factory finish sidesteps that problem entirely. Second, ColorPlus carries its own finish warranty separate from the product warranty, covering fading and peeling for years without repainting. For homeowners who don't want to think about repainting siding on a ten- or fifteen-year cycle, this is the practical reason to spend the extra money on it.
The Product Lines We Work With
| Line | Typical Use |
|---|---|
| HardiePlank | Lap siding, the most common choice on Lynden homes, in smooth or cedar-textured finish |
| HardiePanel | Vertical panel siding, often paired with board-and-batten detailing |
| HardieShingle | Shingle-style siding for accent areas or full facades wanting a traditional look |
| HardieTrim | Trim boards that match the siding's moisture performance, avoiding wood trim rot at transitions |
What Correct Installation Actually Requires
Fiber cement's reputation depends heavily on installation quality, and this is where a lot of problems on other jobsites originate. Manufacturer specs call for correct fastener type and placement, proper clearance from grade and roof lines, factory-primed or factory-finished cut edges sealed in the field, and rain-screen or drainage detailing behind the cladding in a climate like ours. Skipping any of these steps can shorten the life of an otherwise excellent product. We follow Hardie's published installation requirements as a baseline, not a suggestion, because it's the difference between siding that performs for decades and siding that causes warranty disputes.
The Warranty, in Plain Terms
James Hardie backs its fiber cement products with a non-prorated limited warranty that's transferable to a subsequent homeowner, which matters for resale. ColorPlus finish carries its own separate coverage against fading and peeling. We register installations properly so homeowners have that protection on file, not just a receipt in a drawer.
Why This Is Our Only Offer
We don't install LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar, not because those products have no merit anywhere, but because we've made a professional call that Hardie is the right standard for homes in this specific climate, and we'd rather do one thing well than offer a catalog of compromises. If you're planning a siding project in Lynden or anywhere else in Whatcom County, we're happy to walk your home, look at your exposure to weather and salt air, and put together a free, no-pressure estimate for a Hardie system built for it.
