Lynden Siding Two Very Different Materials, One Big Decision
If you're re-siding a home in Lynden, you've probably already run into the two names that dominate every estimate: vinyl and James Hardie fiber cement. They get compared constantly because they sit at opposite ends of the same decision — vinyl wins on sticker price, Hardie wins on almost everything else that determines how your siding looks and performs ten, twenty, and thirty years down the road. This page is meant to help you understand what you're actually choosing between, not just what you'll pay on day one.
We're a James Hardie-only contractor, so you should know where we stand. But we'd rather explain the real trade-offs honestly than pretend vinyl doesn't have a place in the market. It does. We just don't think it's the right long-term fit for most homes in this part of Whatcom County, and we'll walk through why.
What Vinyl Siding Actually Is
Vinyl siding is an extruded PVC (polyvinyl chloride) plastic panel, usually manufactured in a woodgrain or smooth finish and installed in horizontal or vertical planks that lock together and hang loosely on the wall. It's been the most-installed siding material in North America for decades, largely because it's inexpensive, lightweight, and fast to put up. It never needs painting, it resists rot outright because it isn't organic material, and in a lot of climates it does a perfectly adequate job for a long time.
The trade-offs are structural to the material itself, not a manufacturing defect. Vinyl is thin — even premium panels are a fraction of the thickness of fiber cement — and it's designed to expand and contract with temperature, which is why it's installed with loose nailing rather than fastened tight. That same flexibility that lets it handle thermal movement also means it dents, cracks in cold temperatures, and can warp or buckle if it's ever exposed to concentrated heat, including reflected sunlight off a low-E window or a nearby grill. Color is mixed into the plastic rather than applied as a finish, which sounds durable in theory, but UV exposure fades vinyl unevenly over the years, and once it fades there's no repainting it back to match — the whole elevation has to come off.
What James Hardie Fiber Cement Is
James Hardie siding is a composite of Portland cement, sand, and cellulose fiber, cured into a dense, rigid board. It's manufactured in several product lines engineered for different climate stresses — HardiePlank lap siding, HardiePanel for vertical applications, HardieShingle for a shake look, and HardieTrim for fascia and trim work. Whatcom County falls in a marine climate zone, and Hardie makes an HZ10 product line specifically engineered for regions with sustained moisture exposure, which is the formulation we install here.
The material is non-combustible, doesn't expand and contract nearly as much as vinyl or wood with temperature swings, and holds paint and factory finish far better because it's a rigid substrate rather than a flexible one. Most of what we install carries Hardie's ColorPlus finish — a baked-on, multi-coat factory finish that's more UV- and chip-resistant than field-applied paint, and it comes with its own 15-year finish warranty separate from the 30-year non-prorated substrate warranty on the product itself.
Why the Manufacturing Process Matters
The difference in how these two materials are made explains most of the performance gap. Vinyl is extruded thin because thin is cheap and light to ship and install. Fiber cement is pressed and cured thick because the whole point of the product is mass and rigidity — those properties are what make it resist impact, hold a factory finish, and stay flat against the wall instead of rippling in wind or heat. You're not just buying a different look; you're buying a different set of physical properties.
How Lynden's Climate Factors In
Whatcom County sits in a genuinely tough spot for exterior materials. We get salt-laden air moving in off the Strait of Georgia and Bellingham Bay, long stretches of driving rain through fall and winter, and a moss and algae season that runs longer here than almost anywhere else in the state because of the sustained humidity. None of that is exotic — but all of it adds up over the life of a siding job.
- Salt air: accelerates fastener corrosion and can dull or chalk plastic finishes faster than inland exposure.
- Driving rain: tests every seam, lap, and butt joint — a material's dimensional stability under wet-dry cycling matters more here than in a dry climate.
- Moss and algae season: favors surfaces that hold up to periodic pressure washing and cleaning without degrading.
Vinyl handles moisture fine in the sense that it won't rot — it's plastic. But its loose-hung installation depends on a sound, correctly lapped water management system behind it, since the panels themselves aren't a sealed barrier. Fiber cement, installed to Hardie's spec with proper flashing and clearances, manages that same moisture load with a denser, more dimensionally stable material that also tolerates the pressure washing this region's moss growth tends to require.
Installation Sensitivity: The Part Nobody Talks About Enough
Both products are only as good as the installation. But they fail differently when installation is off. Vinyl installed too tight, without allowing for thermal expansion, will buckle and ripple — a cosmetic problem that's visible but rarely structural. Fiber cement installed wrong is a bigger problem: improper fastening, wrong nail spacing, insufficient clearance from grade or roof lines, or unsealed butt joints can let moisture behind the board and cause real damage, and it's also the single most common reason Hardie warranty claims get denied.
This is exactly why we only install Hardie — we're not spreading our crews thin trying to stay fluent in the installation quirks of five different product lines. Every crew on a Hardie job here is following the same manufacturer specs, the same fastening schedule, and the same flashing details, every time.
Cost Comparison
| Factor | Vinyl Siding | James Hardie Fiber Cement |
|---|---|---|
| Material cost | Lower upfront | Higher upfront |
| Installation labor | Faster, generally less labor-intensive | Slower, more labor and skill-intensive |
| Repainting needed | Never repainted, but fades and can't be restored to original color easily | ColorPlus finish holds color for years; can be repainted when desired |
| Typical lifespan | 20-30 years depending on exposure | 30-50+ years with proper installation and maintenance |
| Impact/fire resistance | Can crack or dent; combustible | Resists impact well; non-combustible |
| Resale perception | Neutral to modest | Generally viewed as a premium upgrade |
The upfront gap is real and we won't pretend otherwise. What often gets missed is the cost over the life of the siding — repainting, panel replacement after storm or impact damage, and the eventual full tear-off and replace that vinyl usually needs sooner than fiber cement does. When you spread the cost across the actual service life of each material, the gap narrows considerably, and in a lot of cases the total cost of ownership favors Hardie.
Warranty Structure: Read the Fine Print
Vinyl siding warranties vary a lot by manufacturer and are frequently prorated — meaning the payout for a defect or failure shrinks the longer you've owned the siding, and many exclude labor for replacement after the first few years. James Hardie's warranty on its fiber cement products is non-prorated for 30 years on the substrate, with the ColorPlus finish separately warranted for 15 years, and the warranty is transferable to a new owner if you sell the home within the coverage period — a detail buyers and their agents increasingly ask about here in a market where a lot of Lynden homes trade hands.
Appearance and Long-Term Curb Appeal
Vinyl has improved its woodgrain textures and color range over the years, but it's still a plastic panel, and up close — especially in strong daylight, which we do get here between rain systems — that's usually apparent. Fiber cement takes paint and factory finish the way wood does, with a flatter, more matte, more authentic look, and it holds crisp butt joints and trim lines instead of the slight waviness vinyl can develop with age and heat exposure.
A Practical Checklist Before You Decide
- Ask how long you plan to own the home — a 5-7 year hold changes the math differently than a forever home.
- Ask any contractor for the manufacturer's actual installation spec sheet, not just their word that they "install to code."
- Check whether the warranty is prorated and whether labor is covered for repairs, not just materials.
- Ask what happens to color and finish after 10-15 years of Whatcom County sun, rain, and salt air exposure.
- Get the total project cost broken out by material and labor so you can compare apples to apples against other bids.
- Ask directly whether the crew installing your siding specializes in that specific product, or installs several different systems.
Why We Only Install Hardie
We made the call years ago to specialize in James Hardie exclusively rather than offer vinyl, LP SmartSide, or other fiber cement brands as cheaper alternatives. It's not that those products have no place in the market — it's that we'd rather put our crews' expertise behind one system we can install to spec every single time, on a material that's engineered for exactly the kind of sustained wet-weather, salt-air exposure Lynden and the rest of Whatcom County deal with every year. That focus is also why we stand behind our installation with a workmanship warranty that complements Hardie's own product warranty, rather than juggling different install standards across five different product lines.
If you're weighing vinyl against Hardie for your own home, we're glad to walk through your specific situation — the exposure your walls get, your timeline, your budget — and give you a straight answer, even if part of that answer is which option makes more sense for your situation.
