Bellingham Exterior One Product, No Exceptions
Homeowners ask us fairly often why we don't offer a menu of siding brands the way a lot of contractors do. The answer is simple: we install James Hardie fiber cement siding, and that's it. Not because we have a marketing deal with them, but because after years of working on homes across Bellingham and the rest of Whatcom County, it's the only product we're willing to put our name behind for the long haul.
That's a real limitation, and we think homeowners deserve to know why before they hire us.
What Our Climate Actually Does to Siding
Bellingham sits between salt water and mountains, which sounds nice in a real estate listing but is rough on a building envelope. We get long stretches of driving rain off the Sound, salt-laden air along the waterfront and up into neighborhoods like Fairhaven and Edgemoor, and a moss and algae season that can run eight or nine months out of the year on shaded, north-facing walls. Add in the freeze-thaw cycles we get most winters, and siding here is under more sustained moisture stress than in a lot of the country.
Every siding material handles that differently. Some hold up fine for a while and then show their weaknesses ten or fifteen years in, right when a homeowner is least expecting a siding conversation.
Why We Don't Install the Alternatives
Vinyl
Vinyl is affordable and low-maintenance in the sense that it doesn't need paint. But it's a petroleum-based product that expands and contracts significantly with temperature swings, can warp or bow in coastal wind exposure, and fades over time with no factory refinishing option. In a marine climate with a lot of UV bounce off the water, we've seen enough of that fading and warping firsthand to stop offering it.
LP SmartSide, Cemplank, and other engineered wood or budget fiber cement
Engineered wood products have improved a lot, and treated correctly they perform reasonably well. But wood-based substrates are still wood at their core, meaning moisture intrusion at a cut edge, a nail hole, or a poorly flashed joint can lead to swelling and deterioration in a way fiber cement simply doesn't experience. Given how much rain Whatcom County sees in a normal year, we don't think the margin for installation error is one we want to carry as the contractor.
Primed Spruce and Cedar
Real wood siding, especially cedar, has genuine appeal and a long history in this region. But it demands an ongoing maintenance commitment — re-staining or repainting on a real schedule, careful attention to end grain, and vigilance about the moss and mildew that our damp, shaded lots practically grow on their own. Most homeowners don't want a siding system that punishes them for skipping a maintenance year, and in this climate, that's exactly what raw wood does.
Allura
Allura is a legitimate fiber cement competitor, and on paper it's similar to Hardie in composition. Where we've drawn the line is on the factory finish system, warranty structure, and the depth of engineering behind climate-specific product lines. We'd rather standardize on one system we know thoroughly than install two similar-but-different products and split our expertise.
What Hardie Gets Right
James Hardie fiber cement is non-combustible, dimensionally stable, and doesn't swell or rot the way wood-based products can. It's engineered specifically for different climate zones — the HZ5 product line, which we use here, is formulated for regions with more moisture exposure and freeze-thaw activity, which describes Bellingham well.
The ColorPlus factory finish is baked on under controlled conditions rather than field-painted, which means better color consistency, better adhesion, and a longer runway before repainting is even a conversation. Hardie backs the product with a substantial transferable warranty, which matters if you sell the home before you'd otherwise need to think about siding again.
Installation Still Matters
None of this works if the installation is sloppy. Fiber cement siding depends on correct flashing, proper clearances at grade and roof lines, and factory-spec fastening. A great product installed carelessly can still fail. That's a big part of why we limit ourselves to one system — it lets our crews install the same product, the same way, on every job, rather than switching methods between five different manufacturers' spec sheets.
Is Hardie Right for Every Home?
Honestly, it's not the cheapest option upfront, and if budget is the only consideration, that's worth being upfront about. But for homeowners thinking about the next 20 to 30 years rather than just the next few, we think it's the material that holds up best against what a Whatcom County exterior actually has to deal with.
