Lynden Siding We Get Asked About Vinyl a Lot
Vinyl siding is the most common siding material sold in the country, and there's a reason for that: it's inexpensive, it's fast to install, and it comes in a wide range of colors and profiles. If you're comparing bids for your Lynden home and one of them is vinyl, you're not making a foolish choice by considering it. But we're a fiber cement contractor, and we don't install vinyl on any of the homes we work on. We think homeowners deserve to know exactly why before they decide what goes on their walls.
What Vinyl Does Well
To be fair to the product, vinyl siding has real strengths:
- Lower upfront cost than most other siding materials, including fiber cement.
- No painting required — the color runs through the material itself.
- Wide availability and a large pool of installers who work with it.
- Reasonably low day-to-day maintenance for homeowners who just want to rinse it off once in a while.
If budget is the primary driver and you understand the trade-offs below, vinyl isn't a scam or a bad product on its face. It's a different set of compromises than what we sign up to install.
Where It Struggles — And Why It Matters Here
It Moves With the Weather
Vinyl is a plastic product, and plastic expands and contracts with temperature swings more than fiber cement does. Installers have to leave the panels slightly loose so they can shift without buckling. Done correctly by an experienced crew, that's manageable. Done poorly — over-nailed, caulked shut at the corners, trimmed too tight — you get waviness, oil-canning, and panels that pop loose in a hard wind. Whatcom County gets its share of driving rain and wind off the water, and a siding system that depends on precise, loose-fastened installation to perform is one more thing that has to go right and stay right for decades.
Moisture Doesn't Stop at the Surface
Vinyl siding isn't a sealed skin — it's designed to shed most water while allowing some to get behind it, which is supposed to drain and dry through weep holes at the bottom of each course. That works fine when the wall assembly behind it is properly detailed. In a region with Lynden's long wet season, any weak point in that drainage plane — a poorly lapped seam, a clogged weep hole, siding installed too close to grade — gives moisture more time and more opportunity to sit against the sheathing than it would in a drier climate. We'd rather install a siding material with more mass and a more forgiving moisture profile than rely on perfect drainage detailing holding up for 20-plus years of Pacific Northwest rain.
UV, Salt Air, and Fading
Vinyl's color is mixed into the plastic, but that doesn't make it immune to fading — years of UV exposure will chalk and dull most vinyl siding, especially on south- and west-facing walls. Whatcom County homes, particularly those closer to Bellingham Bay and the Lynden corridor's open exposure, also deal with a measure of salt air that accelerates surface breakdown on a lot of exterior materials. Once vinyl starts to fade or chalk unevenly, there's no repainting your way out of it without specialized prep — the color is the plastic, and replacing a handful of panels years later to match sun-faded originals is close to impossible.
Moss and Algae
Vinyl's smooth, low-mass surface holds surface moisture in shaded, damp spots — exactly the conditions you get under mature trees or on north-facing walls through a long Whatcom County moss season. It's not that vinyl is uniquely bad here; it's that a soft plastic surface in constant damp shade will grow moss and algae like anything else will, and pressure washing it too aggressively can crack or dislodge panels.
Impact and Repair
Vinyl is thin and brittle in cold weather — a stray baseball, a ladder bump, or a hard hailstone can crack a panel. Repair means replacing the whole panel, not patching a spot, and matching faded original color with a new piece rarely looks seamless.
Why We Install James Hardie Instead
James Hardie fiber cement is heavier, denser, and non-combustible, which matters both for durability and for insurance considerations in our region. It's factory-finished with ColorPlus Technology, a baked-on finish that holds color far longer than field-painted or through-body vinyl color under UV and salt air exposure. Hardie's HZ5 product line is engineered specifically for climates like ours — freeze-thaw cycles, sustained moisture, and wind-driven rain — with installation specs built around keeping water out rather than hoping it drains cleanly every time. It also carries a strong transferable warranty when installed to Hardie's specifications, which is the standard we hold every job to.
None of this means vinyl is a scam or that every vinyl installation fails — plenty perform adequately for years. It means that after weighing the trade-offs against what our climate does to exterior materials, we made a call: we only install what we're confident will hold up on a Lynden home for the long haul, and that's Hardie.
If you're weighing your options, we're happy to walk your home, talk through what each material would actually mean for your situation, and give you a free, no-pressure estimate — no obligation to choose us or to choose Hardie.
