Lynden Siding If you've asked three siding contractors in Whatcom County for a quote, there's a decent chance you got three different opinions on vinyl siding. It's the most common siding material installed in America, it's inexpensive, and plenty of homes wear it just fine for years. So it's a fair question: why does a Lynden-based contractor refuse to install it at all?
The short answer is that we made a decision a long time ago to install one product system — James Hardie fiber cement — and stand behind it completely, rather than offer a menu of products with different failure modes, different warranty structures, and different long-term outcomes. This page explains the reasoning, honestly, including what vinyl does well. We're not here to tell you vinyl is junk. We're here to tell you why it's not what goes on a house we put our name on.
What Vinyl Siding Actually Gets Right
Vinyl earned its market share honestly. It's worth naming what it does well before getting into why we don't install it:
- Low upfront cost. Vinyl is typically the cheapest siding material on the market per square foot, materials and labor combined.
- No paint required. Color is mixed into the material, so there's no painting cycle to maintain — at least at first.
- Fast installation. Vinyl panels go up quickly compared to fiber cement, which can shorten project timelines.
- Widely available. Nearly every lumberyard and building supply store in Washington stocks it, and most contractors know how to install it.
For a homeowner on a tight budget who plans to sell within a few years, vinyl can be a reasonable, defensible choice. Our objection isn't that vinyl is worthless — it's that it isn't the right long-term investment for a house that has to survive a Pacific Northwest climate for decades, and it isn't a product we can stand behind with the same confidence we have in fiber cement.
Why Lynden's Climate Is Harder on Siding Than People Expect
Whatcom County doesn't get the dramatic weather that makes national news, but it grinds on a home's exterior in ways that matter over a 20- or 30-year timeline. Three factors specifically work against vinyl siding here:
Salt Air Off the Sound and Strait
Lynden sits inland from Bellingham Bay and the Strait of Georgia, and the maritime air that moves through Whatcom County carries salt content that accelerates the breakdown of certain building materials. Vinyl doesn't rust like metal fasteners can, but the plasticizers that keep vinyl flexible degrade faster under salt-laden, UV-heavy coastal air — which is part of why older vinyl siding in this region often looks chalky, brittle, or faded well before its rated lifespan is up.
Driving Rain and Wind-Driven Moisture
Storms moving in off the water frequently bring rain sideways, not straight down. Vinyl siding is installed with intentional gaps — it's designed to expand and contract with temperature, so panels are never fully sealed at the seams. Under normal rainfall that's not an issue. Under sustained wind-driven rain, though, water can work its way behind panels at the laps, around windows, and at inside corners, where it depends entirely on the water-resistive barrier and flashing details behind the siding to keep the wall assembly dry.
A Long, Damp Moss Season
Whatcom County's moss season isn't a few weeks — it stretches across most of the fall, winter, and spring. Moss and algae need sustained moisture and shade to establish, and north-facing walls, areas under mature trees, and shaded side yards common in Lynden's neighborhoods provide exactly that. Vinyl's textured, low-gloss surface gives organic growth something to grip onto, and because vinyl can't be pressure-washed aggressively without risking cracked or dislodged panels, moss and algae staining tends to accumulate rather than get knocked back each season.
The Real Issue: What Happens Behind the Panel
Most vinyl siding problems people notice — fading, rippling, a panel popping loose in a windstorm — are cosmetic annoyances. The problem we actually care about as installers is what's happening on the other side of the panel, where you can't see it.
Vinyl is a rainscreen product by design: it's meant to shed the majority of water while allowing some moisture to pass behind it, relying entirely on the underlying weather-resistive barrier, proper flashing, and drainage plane to manage anything that gets through. That's a legitimate building science approach — it's not a flaw by itself. The issue is installation sensitivity. Get the flashing details, J-channel placement, or water table wrong, and vinyl will trap moisture against the sheathing rather than draining it, and you won't know until there's a soft spot on a wall or damage inside. Because vinyl doesn't itself absorb or show water damage, minor installation mistakes can go undetected for years.
Fiber cement has its own installation requirements, but the material itself is far more forgiving of small imperfections in the drainage plane, and it doesn't develop the same brittle, UV-degraded condition that turns a minor flashing gap into a bigger problem over time.
Impact Resistance and Wind Performance
Lynden gets its share of windstorms moving off the Strait, plus the occasional hail and wind-driven debris from fall and winter storm systems. This is a practical, not theoretical, concern for siding material choice.
| Factor | Vinyl Siding | James Hardie Fiber Cement |
|---|---|---|
| Impact resistance | Can crack or shatter in cold weather when struck by debris or hail | Resists cracking from typical wind-driven debris impact |
| Wind rating (installed to spec) | Varies by profile; can dislodge or "oil-can" in sustained high wind | Engineered HZ5 products rated for higher wind exposure zones |
| Combustibility | Petroleum-based plastic; can melt or ignite under high heat exposure | Non-combustible fiber cement |
| Cold-weather brittleness | Becomes more brittle and impact-sensitive below freezing | Stable across the Pacific Northwest's typical temperature range |
| Fading over time | Color is through-body but UV exposure still causes gradual fading, especially darker colors | ColorPlus factory finish is baked-on and backed by a separate finish warranty |
The cold-weather brittleness point is worth expanding on. Vinyl becomes noticeably stiffer and more prone to cracking in cold temperatures, and Whatcom County does see hard frosts and the occasional freeze events during winter storm systems. A wind-driven branch or a ladder bump against vinyl siding in January can crack a panel that would have simply dented or scuffed in July.
What "Installed to Spec" Actually Means
Vinyl siding's real-world performance depends heavily on installation quality — arguably more than most siding types, because the panels themselves do very little structural or waterproofing work on their own. A few examples of where installation quality makes or breaks vinyl's performance:
- Nailing technique. Vinyl panels must be nailed loosely, in the center of the nail slot, to allow for thermal expansion. Nail it too tight and the panel can't move with temperature swings, leading to buckling or cracking.
- J-channel and flashing at penetrations. Every window, vent, and fixture penetration needs correct flashing behind the vinyl trim to direct water outward, not behind the panel.
- Starter strip and level lines. A slightly out-of-level starter strip compounds visibly as panels stack up a two-story wall.
- Corner post and utility trim fit. Gaps here are a common entry point for wind-driven rain in coastal storm conditions.
None of this makes vinyl a bad product when installed correctly. It does mean the margin for error is narrow, and because we only run crews trained and certified on Hardie fiber cement systems, we're not in a position to guarantee that same precision on a product we don't specialize in.
Why We Standardized on James Hardie Instead
We install exclusively James Hardie fiber cement siding — not LP SmartSide, not vinyl, not Cemplank or Allura, not primed spruce or cedar. That's a deliberate business decision, not a default. Here's the reasoning:
Non-Combustible Material
Fiber cement is made primarily from cement, sand, and cellulose fibers. It does not melt, ignite, or contribute fuel to a fire in the way vinyl or wood products can. For homes near tree lines or in areas with any wildfire exposure risk, that's a meaningful difference in a home's overall fire profile.
ColorPlus Factory Finish
Rather than color mixed into raw plastic or a field-applied paint job, Hardie's ColorPlus finish is baked onto the board at the factory in a controlled environment, then backed by its own finish warranty separate from the product warranty. That finish holds color and resists the chalking and fading that shows up on plastic siding after years of UV and salt air exposure.
Climate-Engineered Product Lines
Hardie manufactures its HZ (HardieZone) product lines specifically engineered for different climate exposure zones — including the wetter, higher-moisture HZ5 profile appropriate for Pacific Northwest conditions. That's a level of climate-specific engineering vinyl manufacturers generally don't offer, because vinyl's chemistry doesn't change region to region.
A Warranty Structure We Can Stand Behind
Hardie backs its fiber cement products with a long transferable limited warranty, plus the separate ColorPlus finish warranty. Because it's the only system we install, we know it inside and out — install specs, flashing details, fastener schedules — and we can back our own workmanship warranty with confidence, rather than guessing at a manufacturer's fine print on a product we install occasionally.
Long-Term Moss and Algae Resistance
Fiber cement's harder, denser surface holds up better to periodic washing than vinyl does, which matters directly in a region with a moss season as long as Whatcom County's. Homeowners can clean it more aggressively without the cracking risk vinyl carries.
What to Weigh If You're Choosing Between Vinyl and Fiber Cement
If another contractor has quoted you vinyl and you're trying to figure out whether that's the right call for your Lynden home, here's a practical checklist to work through:
- How long do you plan to own the home — a quick flip, or a decades-long stay?
- Is your home on a north-facing lot or shaded by mature trees, where moss pressure will be higher?
- Are you close enough to the water or open farmland that wind exposure is a real factor?
- Does your homeowners insurance or mortgage lender have any fire-rating preferences for exterior materials?
- What's the installing contractor's actual experience — do they specialize in the product, or install it occasionally alongside several other siding types?
- How does the manufacturer's warranty read in the fine print, particularly around labor coverage and what voids it?
There's no universally "right" answer for every homeowner — budget and timeline are real constraints. But for a company that installs one product exclusively and puts its name behind that installation for decades, fiber cement was the only choice that matched the climate we're actually building in.
Cost Perspective, Honestly
We won't quote you fake numbers, but the general shape of the cost comparison is worth understanding: vinyl siding typically has a lower installed cost than James Hardie fiber cement, largely due to material cost and faster installation labor. That gap is real and it's the main reason vinyl remains popular. What it doesn't reflect is the total cost of ownership — repainting or refinishing cycles some vinyl eventually needs as it fades, replacement of cracked panels after storm or impact damage, and the resale and curb-appeal difference buyers in this market often notice between vinyl and fiber cement homes. We'd rather walk you through that full picture during an estimate than let a lower number on a quote sheet be the only thing you compare.
