Ferndale Vinyl Siding Looks Fine on the Truck. It's the Next 20 Years We Worry About.
Vinyl siding is the most common siding material sold in this country, and there's a reason for that: it's inexpensive, it goes up fast, and it never needs painting. If you're comparing bids for a home in Ferndale, you've probably had at least one contractor offer it. We don't. This page explains why, without pretending vinyl is a bad product — it isn't. It's just not the product we're willing to put our name on here in Whatcom County.
What Vinyl Siding Actually Gets Right
To be fair to it: vinyl is lightweight, budget-friendly, and low-maintenance in the sense that it never needs a repaint. In dry, moderate climates it can perform reasonably well for a couple of decades. Millions of homes wear it without major issues. It's not a scam product — it's a product built for a price point, and the trade-offs that come with that price point are what concern us for homes on the coast.
Why We Don't Put It on Homes Near Bellingham Bay
Salt Air and Wind-Driven Rain Find Every Gap
Ferndale sits close enough to the water that salt-laden air and driving rain off the Strait of Georgia are a fact of life, not an occasional storm event. Vinyl siding is installed in overlapping panels that are designed to move — it expands and contracts with temperature, and it's hung loosely on a nail hem rather than fully fastened flat. That movement is normal for vinyl, but it also means the panels rely on lap joints and J-channels to keep water out rather than a continuous, rigid barrier. In a climate with this much sideways rain, water finds its way behind the panels more often than homeowners expect, and vinyl was never designed to be a waterproof skin on its own — it's designed to shed most water while the house wrap behind it does the real work.
UV, Salt Spray, and Long-Term Fading
Vinyl color is baked into the plastic, which sounds durable — and it resists fading better than a painted surface for the first several years. But UV exposure combined with salt air over time does chalk and fade vinyl, especially darker colors, and unlike paint you can't refresh it with a new coat. Once a run of vinyl fades unevenly or a panel cracks in a cold snap and needs replacing, matching 10-year-old vinyl to new stock is close to impossible because manufacturers change their color lines. You end up with a visibly mismatched patch on the side of the house.
Moss Season and Trapped Moisture
Whatcom County's long wet season means moss and algae growth on north-facing walls and shaded siding runs is a normal seasonal reality, not a sign of neglect. Vinyl's lap-and-channel design creates small ledges and gaps where moisture, pollen, and organic debris collect and stay damp longer than a flatter, harder surface would. That's a maintenance issue more than a structural one, but it means more scrubbing and pressure-washing over the life of the siding than homeowners are usually told to expect when they buy vinyl for its "low maintenance" reputation.
Impact and Heat Sensitivity
Vinyl is a plastic product, and plastic behaves like plastic. It gets brittle in cold weather and can crack from a stray branch, a ladder bump, or hail. It can also warp or buckle if something reflective — a dark storm shutter, a grill, even certain window films — bounces concentrated heat back onto a wall. None of that makes it a bad product for its price category, but it does mean it's a less forgiving material than fiber cement when it comes to the kind of everyday bumps and weather swings a coastal Washington property sees.
Warranty Structure
Most vinyl warranties are prorated — full coverage in the early years, declining coverage after that, and they typically cover material defects only, not labor, and not fading within "normal" tolerances (which is defined generously by the manufacturer, not the homeowner). When a covered issue does show up ten or fifteen years in, the payout is often a fraction of what a full re-side would cost.
Why We Standardized on James Hardie Instead
We install James Hardie fiber cement exclusively, and the reasons track directly against the vinyl trade-offs above:
- Non-combustible material — fiber cement doesn't burn, melt, or contribute fuel in a wildfire exposure the way plastic siding can.
- ColorPlus factory finish — a baked-on finish engineered to hold color and resist fading, chalking, and salt-air wear far longer than field-applied paint or dyed vinyl.
- HZ5 formulation — Hardie's HZ product lines are engineered for specific climate zones, including wet, freeze-thaw Pacific Northwest conditions, rather than a one-size-fits-all panel.
- Rigid, fastened installation — Hardie boards are nailed flat and solid to the wall, not hung loosely to expand and contract, which changes how the whole assembly handles wind-driven rain.
- A stronger, more straightforward transferable warranty — backed by a large, established manufacturer with decades of product history in wet coastal climates.
Fiber cement costs more up front than vinyl, and it's heavier and slower to install — installation quality matters more, which is exactly why we only install it ourselves, to spec, rather than subcontracting it out. For a home that's going to sit through decades of Whatcom County rain, salt air, and moss season, we think that trade-off is worth it.
