Anacortes One Product, One Standard
Homeowners sometimes ask why our quotes don't include options for vinyl, LP SmartSide, or a cheaper fiber cement alternative. The answer is simple: we made a decision years ago to install James Hardie siding exclusively, and we haven't second-guessed it. That's not a marketing gimmick or a manufacturer kickback story — it's a practical response to what actually happens to siding on homes in Anacortes and the rest of Skagit County over ten, twenty, and thirty years.
Specializing in one system means our crews install it the same correct way on every job, our estimates are consistent, and we stand behind a product we've watched perform in this exact climate. This page explains the reasoning, not just the sales pitch.
What Anacortes Weather Actually Does to Siding
Anacortes sits at the edge of Fidalgo Island, surrounded by the Salish Sea, Guemes Channel, and Padilla Bay. That location is beautiful and it is also hard on exterior building materials for three specific reasons.
Salt Air
Marine air carries fine salt particles that settle on siding, trim, and fasteners. Over time salt accelerates corrosion in fasteners and metal flashing, and it can degrade paint films and some composite materials faster than an inland location would see. Any siding product marketed for this area needs to hold up to that exposure without constant re-coating.
Driving Rain
Storms coming off the Strait of Juan de Fuca and Rosario Strait don't just fall straight down — wind-driven rain hits walls at an angle, especially on west and southwest exposures. That means water finds its way into every gap, seam, and fastener penetration that isn't detailed correctly. Siding that swells, warps, or wicks moisture at the edges is a liability here in a way it might not be in a drier climate.
Moss and Prolonged Dampness
Skagit County's wet season runs long, and shaded north-facing walls, tree-lined lots, and homes near the water can stay damp for weeks at a stretch. That's ideal for moss and algae growth on siding surfaces, and it's a slow, steady test of how well a material resists moisture absorption and biological growth over its lifespan.
Why We Stopped Installing Other Products
We didn't start out installing only Hardie. Like most contractors in this region, we installed a mix of vinyl, engineered wood, and fiber cement products depending on budget and homeowner preference. What changed our approach was watching how those products aged on real homes in real Anacortes weather over multiple years — not in a lab, not in a showroom, but on job sites we returned to for repairs, repaints, and replacements.
Vinyl
Vinyl is inexpensive and low-maintenance in the sense that it never needs painting, but it's a thin plastic product that can crack in impacts, fade unevenly in UV exposure, and warp or buckle when installed too tight or exposed to reflected heat. In a marine climate with real weather extremes, it's the product we're least comfortable standing behind for a homeowner's long-term investment.
Engineered Wood (LP SmartSide and Similar)
Engineered wood siding has real strengths — it's lighter than fiber cement and easier to install — but it's still wood at its core, treated and resin-coated to resist moisture. Any breach in that coating, whether from a fastener hole, a cut edge left unsealed, or years of driving rain finding a seam, opens the door to swelling and rot. In a climate with as much sustained moisture as ours, that's a risk we're not willing to take on a homeowner's behalf.
Other Fiber Cement Brands (Cemplank, Allura)
These are legitimate fiber cement products and share the same base chemistry as James Hardie. Our decision here isn't about the material science — it's about factory finish quality, product line engineering for specific climates, warranty structure, and the depth of installer training and support available. We chose to standardize on the brand with the strongest track record and support system rather than juggle multiple product lines and warranty processes.
Primed Spruce and Cedar
Natural wood siding is beautiful, and there's a reason it's a classic look in the Pacific Northwest. But it demands a maintenance commitment — regular repainting or restaining, caulking, and vigilance against moisture and pests — that most homeowners underestimate when they choose it. In a moss-prone, high-rainfall county, that maintenance burden compounds quickly.
What James Hardie Gets Right for This Climate
James Hardie fiber cement siding is made from cement, sand, and cellulose fibers, engineered specifically to resist the conditions that cause other sidings to fail here.
- Non-combustible core — fiber cement doesn't burn, which matters increasingly as wildfire smoke and ember exposure become part of Pacific Northwest summers.
- Moisture resistance — engineered to resist swelling, cracking, and warping from prolonged rain exposure and humidity when installed to specification.
- Factory-applied ColorPlus finish — a baked-on finish that resists fading and chipping far better than field-applied paint, which matters when salt air is working against every painted surface on a house.
- Climate-specific product engineering — Hardie's HZ5 formulation is engineered for regions with freeze-thaw cycles and moisture exposure, which fits Skagit County's climate profile.
- Pest resistance — cement-based siding isn't a food source for insects the way wood-based products can be.
How Correct Installation Prevents Problems
Even the best siding product fails if it's installed wrong, and this is where a lot of the horror stories about any siding brand actually originate. James Hardie publishes detailed installation requirements, and skipping them is the single biggest cause of premature siding failure we see when we're called out to look at another contractor's work.
Fastener Placement and Type
Hardie requires specific nail or screw types, placement, and spacing. Using the wrong fastener or driving it too deep or too shallow can crack the board or leave a gap that lets water in — and in a salt-air environment, the wrong fastener metal will corrode faster than the siding around it.
Clearances and Flashing
Proper installation requires clearance from grade, roof lines, decks, and other siding terminations, along with correct flashing at every window, door, and penetration. Skipping these details is invisible on install day and shows up as water damage two or three winters later — exactly the kind of driving-rain failure this region punishes.
Caulking and Joint Treatment
Butt joints, corners, and trim intersections need to be treated correctly to shed water rather than trap it. This is detail work that takes time, and it's often where corners get cut on rushed jobs.
Painting Cut Edges
Any field-cut edge of a Hardie board needs to be sealed with the appropriate product before installation. An unsealed cut edge is a moisture entry point, no matter how good the rest of the installation is.
Comparing the Options Side by Side
| Factor | Vinyl | Engineered Wood | James Hardie Fiber Cement |
|---|---|---|---|
| Moisture resistance in driving rain | Fair — seams and gaps vulnerable | Good if coating stays intact; fails if breached | Strong when installed to spec |
| Salt air / marine exposure | Fades, can become brittle | Moderate; depends on coating integrity | Factory ColorPlus finish resists fade and salt exposure |
| Fire resistance | Melts, combustible | Combustible (wood-based) | Non-combustible |
| Maintenance | Low, but limited repair options | Moderate — repainting and edge sealing over time | Low with factory finish; repaint interval much longer |
| Typical lifespan when correctly installed | 20-30 years | 20-30 years | 30-50+ years |
| Upfront cost | Lowest | Mid-range | Higher upfront, lower lifetime cost |
The Warranty Difference
James Hardie backs its siding products with a transferable limited warranty, and the ColorPlus factory finish carries its own separate finish warranty. Transferability matters in a place like Anacortes where homes change hands regularly — a documented, brand-backed warranty is a real selling point when a homeowner eventually lists the house. We keep our installations aligned with Hardie's published requirements specifically so that warranty coverage stays intact if it's ever needed.
What This Means for Your Project
Standardizing on one product doesn't mean every Hardie job looks the same. Hardie offers multiple siding profiles — lap siding, shingle-style panels, board and batten, and trim — in a range of ColorPlus finishes, so there's real design flexibility within the system. What stays consistent is the substrate, the installation standard, and the warranty backing.
Questions Worth Asking Before You Hire Any Siding Contractor
- Are they certified or specifically trained on the product they're proposing to install?
- Will they show you the manufacturer's installation instructions and follow them, including fastener spacing and clearances?
- Do they seal cut edges and treat joints correctly, not just on the parts you can see?
- Is the warranty from the manufacturer transferable, and does it stay valid based on how the job is installed?
- Have they worked on homes in your specific microclimate — waterfront, shaded lot, exposed hillside — and can they explain how that changes the approach?
