Deming sits back from the coast, tucked into the Nooksack River valley on the way up to Mount Baker, and that changes the calculus a bit compared to a lot in downtown Bellingham. Homes here tend to sit under heavy stands of Douglas fir, cedar, and big-leaf maple, which means more shade, slower drying after a storm, and more organic debris landing against the walls than a home out in the open. Cold air also pools in this stretch of the valley on clear winter nights, so Deming sees harder frosts and more freeze-thaw cycling than Bellingham's waterfront neighborhoods.
For a full re-side on a shaded, damp lot, or any home close to the river bottom where humidity lingers, James Hardie fiber cement is generally the more durable long-term choice. It does not rot, does not feed fungal growth the way wood-based products can, and shrugs off freeze-thaw once it is properly caulked and painted. For a detached shop, a secondary structure, a rental on a tight budget, or a home on open, well-drained pasture ground with good sun exposure to dry things out, vinyl remains an honest and reasonable option, as long as the flashing and house wrap underneath are done correctly. Neither product is the automatic right answer everywhere in Whatcom County — the site conditions and your maintenance appetite should drive the decision.
James Hardie siding is made from a blend of Portland cement, sand, and cellulose fiber, pressed and cured into planks, panels, or shingle-look pieces. Because it is a mineral-based product rather than wood or a wood derivative, it does not absorb water the way solid wood siding does, and it will not rot, delaminate, or attract carpenter ants and other wood-boring insects the way older cedar siding around Deming sometimes does after decades of exposure. It is also non-combustible, which some homeowners near the forested edges of town appreciate given the wildfire smoke seasons the region has seen in recent summers, even though Whatcom County itself is not a high wildfire-risk area.
The ColorPlus factory-finish option holds its color and resists fading far longer than field-applied paint, which matters in a climate where UV exposure is moderate but moisture cycling is constant. Standard primed Hardie board will still need repainting on a longer cycle than wood, typically somewhere in the 10-to-15-year range depending on sun exposure and how well the original paint job was done. The board itself is heavy — noticeably heavier than vinyl or even most wood lap siding — which means installation takes an experienced two-person crew and the correct fastening schedule; done poorly, planks can crack or blow out at the nail line. Alpine Exteriors crews who install Hardie siding pay close attention to butt-joint flashing and caulking details, because even though the board itself will not rot, water that gets behind an improperly sealed joint can still damage the sheathing underneath — a real risk given how much rain Whatcom County sees in a typical fall and winter.
Cost is the main drawback. Fiber cement runs meaningfully higher than vinyl in both material and labor, and the weight of the product adds to installation time. It is not a weekend DIY project for most homeowners, and repairs to damaged boards require matching paint and cutting tools most people do not keep on hand.
Vinyl siding is an extruded PVC panel product that interlocks in horizontal courses, available in a range of profiles including traditional double-4 and double-5 clapboard, Dutch lap, and shake-look styles. It is light, which keeps labor time and cost down, and it never needs painting — a wash with a garden hose or soft-bristle brush a couple of times a year handles most of the moss and algae film that builds up on siding kept in shade under Deming's tree cover.
The tradeoffs show up in colder weather. Vinyl becomes noticeably more brittle as temperatures drop, and Deming's foothill location means harder overnight frosts than the lowland parts of the county. A branch coming down in a windstorm, a stray piece of firewood, or even a sled or ladder bumping the wall on a cold day is more likely to crack a vinyl panel here than it would be on a mild afternoon near the water. Vinyl also expands and contracts significantly with temperature swings, so it has to be hung loose in its nailing hem per the manufacturer's spec — installers who nail it too tight will see panels buckle or oil-can once the weather turns.
The other real drawback is what happens behind the panels. Vinyl siding is not a water barrier by itself; it is designed to shed most rain while relying on the house wrap and flashing behind it to manage anything that gets through the seams, corners, and utility penetrations. In a climate that sees as much sustained rainfall as Whatcom County does, a house wrap detail done wrong — a missing flashing tape, a poorly lapped seam around a window — can let moisture reach the OSB or plywood sheathing behind the siding, and vinyl will hide that damage for years because the surface itself never rots or stains the way exposed wood would. Vinyl siding is not a bad product, but it puts more weight on the quality of the water-management layer underneath it than fiber cement does.
| James Hardie Fiber Cement | Vinyl | |
|---|---|---|
| Installed cost | Higher — roughly in the $9–$16 per square foot range installed, depending on profile and trim detail | Lower — roughly in the $4–$8 per square foot range installed, depending on panel thickness and profile |
| Realistic lifespan | Commonly 35–50 years with proper caulk and paint maintenance; Hardie's own product warranty is non-prorated for decades | Commonly 20–30 years in this climate; UV and cold-weather brittleness tend to be the limiting factors rather than color fading alone |
| Maintenance | Periodic wash for moss/algae film, repaint every 10–15 years unless ColorPlus finish, occasional caulk inspection at joints and trim | Periodic wash for moss/algae film, no repainting, but cracked or warped panels usually need full replacement rather than spot repair |
| Appearance | Authentic wood-grain or smooth textures, crisp painted lines, full range of colors including deep tones without warping | Wide style range but color choices skew lighter to mid-tone since dark colors can warp in direct sun; seams and panel joints are more visible up close |
Deming's housing stock runs from older ranch homes on wooded acreage to riverside cabins along the Mount Baker Highway corridor, plus a fair number of manufactured and modular homes built in the 1970s through 1990s that are now due for a full re-side. The common thread on most of these lots is shade and moisture: mature conifers block direct sun for much of the day, gutters and roof valleys dump extra water onto certain wall sections, and the ground itself holds moisture longer than it would on an open lot closer to Bellingham Bay. Those are exactly the conditions where fiber cement earns its higher price tag — a wall that stays damp for days after a storm is a wall where wood-based or moisture-sensitive materials eventually show it, while Hardie board simply does not care.
Where we'd steer a homeowner toward vinyl instead: a detached shop or garage without the same rain exposure as the main house, an addition on a budget where the main structure is staying as-is, or a home on cleared, well-drained pasture ground that actually gets sun on most elevations. In those situations vinyl's lower cost is a legitimate advantage, not a corner cut, as long as the house wrap and flashing are installed correctly the first time.
One more factor worth raising with your contractor: any re-side that counts as a substantial remodel may need to meet current Washington State Energy Code wall assembly requirements, which often push toward adding continuous exterior insulation rather than relying on cavity insulation alone. Both fiber cement and vinyl can be installed over rigid foam with furring strips or foam-backed panels, but the fastening and flashing details differ between the two products, and getting them wrong undermines both the energy performance and the water management of the wall. This is a detail worth confirming before work starts, not after the siding is already up. Alpine Exteriors installs both fiber cement and vinyl siding across Whatcom County and works through this kind of site-by-site tradeoff with homeowners rather than defaulting to one product for every house, and we hold Washington contractor license ALPINI751OW for any work we perform in Deming and the surrounding area.
For wall sections that stay damp for extended periods — shaded elevations, walls near dense tree cover, or spots where gutters overflow — yes, fiber cement has a clear edge because it does not rot and does not feed the fungal growth that wood-based materials are prone to in a persistently wet climate. Vinyl handles rain fine as a surface material, but it depends entirely on correct flashing and house wrap behind it, so its real-world performance is more dependent on installation quality than fiber cement's is.
It can. Vinyl becomes more brittle as temperatures drop, and Deming's foothill location sees colder overnight lows and harder frosts than lowland parts of the county, so an impact from a falling branch, firewood, or equipment is more likely to crack a panel here on a cold day than it would be in milder weather closer to the water. This isn't a reason to rule vinyl out, but it's a real maintenance consideration worth planning for, especially on wooded lots.
It can, indirectly. The Washington State Energy Code governs the performance of the whole wall assembly, not just the cladding, and many remodels that trigger code review end up needing continuous exterior insulation to meet current prescriptive requirements. Both fiber cement and vinyl can be installed over rigid foam, but the furring, fastening, and flashing details differ between the two, so it's worth confirming the wall assembly plan with your contractor before the siding choice is finalized.
Yes, and it's fairly common — for example, fiber cement on street-facing or rain-exposed elevations with vinyl on a detached garage or a less-exposed rear wall. The main requirement is that the transition points between the two materials are flashed correctly so water doesn't get trapped where the two systems meet; a contractor experienced with both products should treat that detail as a normal part of the job rather than an afterthought.
