Burlington Two Products, Two Very Different Philosophies
Vinyl and fiber cement solve the same problem — protecting a house and giving it a finished look — in almost opposite ways. Vinyl is a thin, flexible plastic panel designed to be inexpensive and fast to install. Fiber cement is a dense, engineered board made of cement, sand, and cellulose fiber, designed to behave more like a permanent building material than a plastic wrap. Neither is a scam or a rip-off. They're built for different priorities, and in a climate like Skagit County's — salt air off the Sound, driving winter rain, and a moss season that can stretch from October through May — those priorities matter a lot more than they would in a dry inland climate.
This page lays out where each product actually performs, where the marketing glosses over real trade-offs, and why our company made the decision to install James Hardie fiber cement exclusively rather than offer both.
What Vinyl Siding Gets Right
We're not going to pretend vinyl doesn't have real advantages, because it does:
- Lower upfront material cost — vinyl panels are generally the least expensive siding option on the market.
- Fast installation — lightweight panels go up quickly, which can mean less labor cost and a shorter project timeline.
- No paint required — color is baked into the plastic, so there's no finish coat to maintain in year one.
- Reasonably weather-resistant when new — a properly installed vinyl job will shed water fine for the first several years.
For a homeowner on a tight budget who plans to sell in a few years, vinyl is a legitimate, honest option. The problems show up over the longer haul, and they show up faster here than they would in a milder, drier climate.
Where the Marketing Gets Ahead of the Product
Vinyl is often sold as "maintenance-free." That's true in the sense that it never needs painting — but it's not true in the sense that it never needs attention. It still needs regular washing to keep moss and algae from taking hold, it still needs caulking checked, and it still needs replacement when panels crack, fade unevenly, or blow off in a windstorm. "Low maintenance" is a fairer description than "maintenance-free."
Where Vinyl Struggles in Skagit County's Climate
Burlington sits close enough to the water that salt-laden air is a constant, low-grade stressor on exterior materials, and our winters bring long stretches of driving rain rather than short, intense storms. That combination is specifically hard on vinyl for a few reasons:
Moisture Behind the Panels
Vinyl siding isn't watertight — it's designed to let some water get behind it and drain out through weep holes at the bottom of each panel. That works fine when everything is installed correctly and the wall assembly behind it is sound. But in a region with this much sustained rainfall, any gap in the house wrap, any poorly lapped J-channel, or any settling that opens a seam gives moisture more opportunities per year to find its way in than it would somewhere drier. Once trapped moisture reaches sheathing, the damage is often invisible until a wall is opened up.
Moss, Algae, and the Long Wet Season
Vinyl's textured, low-gloss surface holds onto moisture and organic growth more than a smooth, factory-finished surface does. In a climate where moss has essentially a seven-month growing season, north-facing walls and shaded elevations can develop persistent green and black staining that requires regular pressure washing to control — and aggressive washing over time can stress seams and fasteners.
Thermal Movement and Fading
Vinyl expands and contracts with temperature more than fiber cement does, which is why it's installed with "float" allowances rather than face-nailed tight. Over years of freeze-thaw cycling and UV exposure, panels can warp, buckle, or fade unevenly — and because color is mixed into the plastic itself rather than applied as a finish, faded or damaged panels are difficult to color-match years later, especially if that exact profile or shade has been discontinued.
Wind Exposure
Open, wind-exposed lots around Burlington and along the valley see gusts strong enough to lift poorly fastened or aging vinyl panels off the wall. It's rarely catastrophic, but it's a recurring repair call.
What Fiber Cement Gets Right
James Hardie fiber cement was engineered specifically to solve the failure modes that plague other siding materials in wet, coastal-influenced climates:
- Dimensional stability — fiber cement barely expands or contracts with temperature and humidity swings, so seams stay tight and paint lines stay clean for years.
- Non-combustible core — it won't ignite, warp, or melt from a nearby fire source the way vinyl or wood products can.
- Factory-applied ColorPlus finish — baked-on, UV-cured color that resists fading and chalking far longer than field-applied paint, with touch-up product available for repairs.
- Engineered for moisture climates — Hardie's HZ5 product line is specifically formulated for the Pacific Northwest's freeze-thaw and high-moisture conditions.
- Resists moss and pest damage — it doesn't feed insects and its harder, smoother factory finish sheds algae and moss more readily than textured vinyl.
Fiber cement isn't cheap, and it isn't the fastest thing to install. It's heavier, requires specific fastening patterns, and needs to be cut and handled correctly to control silica dust. But the physical properties are a much closer match to what this climate actually demands over a 30-to-50-year house life rather than a 10-to-15-year siding life.
Installation Sensitivity: The Part Nobody Talks About
Both products can fail early — not because the material is bad, but because installation cut corners. The difference is how forgiving each product is of imperfect work.
| Factor | Vinyl Siding | Fiber Cement (Hardie) |
|---|---|---|
| Tolerance for installer error | Fairly forgiving short-term, but hidden moisture errors surface as rot years later | Less forgiving — clearances, fastening, and flashing must follow manufacturer spec exactly |
| Sensitivity to caulking/sealant quality | Moderate — relies on lapped joints and weep design | High — proper joint treatment and paint-grade caulk are essential to performance |
| Fastening requirements | Must "float," not be nailed tight | Must be face-nailed per stud with correct penetration depth |
| Cutting/handling requirements | Simple hand tools | Requires dust-controlled cutting methods (score-and-snap or shears) |
| Consequence of a bad install | Buckling, gaps, moisture intrusion behind panels | Cracking, moisture wicking at cut edges, premature paint failure |
This is exactly why "who installs it" matters as much as "what you install." A poorly installed Hardie job can underperform a well-installed vinyl job — which is why we treat installation discipline as part of the product, not an afterthought.
Cost Over Time, Not Just Cost at Closing
Sticker price alone is a misleading way to compare these two products. Here's a more honest framing of where the money actually goes:
| Cost Factor | Vinyl | Fiber Cement (Hardie) |
|---|---|---|
| Upfront material + install | Lower | Higher |
| Typical repaint/refinish need | Never repainted, but color fades and can't be matched perfectly | ColorPlus finish holds 15+ years before touch-up is typically needed |
| Moss/algae cleaning frequency | More frequent in shaded, wet areas | Less frequent due to smoother factory finish |
| Storm/wind damage repair | More common on exposed elevations | Rare when installed to spec |
| Expected service life | 15-25 years before full replacement | 30-50+ years with proper installation and care |
Run the math over one full ownership cycle rather than one project bid, and the gap narrows or reverses.
Warranty: Read the Fine Print
Warranty length isn't the whole story — what's covered and what voids it matters just as much. Vinyl warranties are often prorated, meaning the payout shrinks the longer you've owned the siding, and many are non-transferable to a new owner if you sell. James Hardie's warranty on ColorPlus products includes a substantial non-prorated period on both the substrate and the factory finish, and it's transferable to a subsequent homeowner within the coverage window — something that matters for resale in a market where buyers increasingly ask what the siding is and how old it is.
A Checklist for Comparing Bids Yourself
Whatever you decide, ask any contractor these questions before signing anything:
- Is the warranty prorated, and does it transfer if I sell the house?
- What's the manufacturer's specified fastening pattern, and will you follow it exactly?
- How will you flash windows, doors, and butt joints against wind-driven rain?
- What's your plan for controlling silica dust if fiber cement is being cut on site?
- Can I see the specific product line and finish, not just "vinyl" or "Hardie" as a generic term?
- What does the manufacturer's own installation manual say about clearance from grade, decks, and roof lines?
Why We Only Install James Hardie
We made the decision years ago to stop offering vinyl, LP SmartSide, and other fiber cement brands and install exclusively James Hardie. Not because every alternative is a bad product, but because we wanted to stand behind one system we can install to spec every time, back with a warranty worth having, and trust to hold up through another Skagit County winter of salt air, sideways rain, and moss. Standardizing on one product also means our crews aren't relearning different fastening and flashing rules from job to job — they get it right because it's the only thing they do.
If you're weighing vinyl against fiber cement for your own home, we're glad to walk the property with you, point out the specific exposures that matter most on your house, and give you a straight, no-pressure estimate for what a correctly installed Hardie system would cost.
