Blaine Exterior We Get Asked About Vinyl a Lot
Vinyl siding is the most common siding material installed in America, and there's a reason for that. It's inexpensive, it goes up fast, and in a lot of climates it holds up fine for years with almost no attention. If you've priced out a siding job and vinyl came in well below everything else, that's not a sales trick — it's genuinely a lower-cost product to manufacture and install. We're not going to pretend otherwise.
But we don't install it. Not because it's a bad product in general, but because of what happens to it specifically here in Blaine, sitting on the water at the edge of Whatcom County, with salt air off the Strait of Georgia, wind-driven rain that comes in sideways off Boundary Bay, and a moss season that runs most of the year. Vinyl's weak points line up almost exactly with our weak points as a climate. Here's the honest breakdown.
What Vinyl Siding Actually Gets Right
- Upfront cost. It's typically the cheapest siding option installed, both material and labor.
- Low maintenance in dry climates. No painting required, and it won't rot like untreated wood.
- Wide color and profile availability. Manufacturers offer a lot of styles, including options that mimic wood grain or shake.
If you live somewhere hot and dry with mild winters, a lot of vinyl's downsides simply don't apply as hard. That's not our climate.
Where It Struggles on the Whatcom County Coast
Salt Air and Fastener Corrosion
Vinyl panels themselves don't rust, but they're hung with nails or staples, and the trim, flashing, and accessory pieces around windows and corners often aren't rated for coastal exposure. Blaine's proximity to salt water accelerates corrosion on anything metal that isn't specifically built for a marine environment. Over years, that shows up as streaking, loosened panels, and trim that fails before the siding field does.
Wind-Driven Rain Behind the Panels
Vinyl siding is installed as an overlapping shingle system, not a sealed skin — it's designed to let some water get behind it and drain back out. That works fine in light rain. It works less well when rain is being driven sideways by wind off open water, which is a normal weather pattern here. Water pushed hard enough can get past the laps and into the wall assembly, where it depends entirely on the house wrap and flashing behind it to keep the structure dry.
Moss, Algae, and a Long Wet Season
Whatcom County doesn't really have a short moss season — north-facing walls and shaded elevations can stay damp for months at a stretch. Vinyl's slightly textured surface and horizontal laps give algae and moss something to hold onto, and because the material can't be pressure-washed aggressively without damaging the panels or driving water behind them, cleaning it is more delicate than most homeowners expect.
Expansion, Contraction, and Impact
Vinyl expands and contracts with temperature swings more than fiber cement does, which is why it's installed with slotted nail holes that allow it to move. Installed even slightly wrong — too tight, wrong nail placement — it buckles or waves, and that's a workmanship issue that shows up years later, not on install day. It's also more prone to cracking on impact in cold weather, which matters when winter temperatures dip and wind carries debris.
The Warranty Fine Print
Vinyl warranties often look long on paper, but many are prorated after the first several years, meaning the manufacturer's payout shrinks over time even if the product fails. Labor to remove and reinstall is frequently excluded or capped. It's worth reading the actual document, not just the headline number.
Why We Install James Hardie Instead
We standardized on James Hardie fiber cement for every siding job we do, and it comes down to how the product behaves in exactly the conditions above. It's non-combustible. It's dimensionally stable, so it doesn't expand and contract the way vinyl does, which matters through our seasonal temperature swings. The ColorPlus factory finish is baked on under controlled conditions rather than applied on site, and it's built to resist fading and hold up against sustained moisture exposure better than a field-painted or extruded surface. Hardie also engineers specific product lines — including HZ5 formulations — for climate zones like ours, accounting for moisture exposure rather than treating every region the same. The warranty is transferable and isn't structured around the same proration that trips people up with vinyl.
None of this means Hardie is maintenance-free or that it's the right answer for every budget. It costs more upfront than vinyl, and it has to be installed to spec — proper clearances, fastening, and caulking — to perform the way it's designed to. But when we weigh install cost against how a product actually holds up on a house facing salt air, driving rain, and a long moss season, fiber cement is what we're willing to put our name on.
