Skagit County One Product, One Standard
We get asked fairly often why we don't offer more options — vinyl, LP SmartSide, cedar, or one of the other fiber cement brands like Cemplank or Allura. The honest answer is that after years of installing and repairing siding across Skagit County, from Anacortes and La Conner out to Sedro-Woolley and Mount Vernon, we settled on James Hardie fiber cement as the only product we stand behind for new installs and full replacements. This page explains why.
What Skagit County Siding Actually Deals With
Our climate isn't dramatic, but it's relentless. Homes near Fidalgo Bay, Padilla Bay, and the greater Salish Sea coastline take on salt-laden air that accelerates corrosion and finish breakdown. Inland, the driving rain off the Cascade foothills and the Skagit Valley's long wet season keep siding wet for days at a time. Add in a moss and algae season that can run from October through May on north-facing walls and shaded lots, and you have conditions that punish any material with a weak moisture strategy or a finish that can't hold up to constant UV-and-rain cycling.
This is the lens we use to evaluate every siding product, not marketing claims.
Why Fiber Cement, Specifically
James Hardie siding is fiber cement: sand, cement, and cellulose fiber, cured into a rigid, dimensionally stable board. It doesn't absorb water the way wood-based products can, it won't support combustion, and it doesn't expand and contract with temperature swings the way vinyl does. In a region where a house might see 60 inches of rain a year along with occasional wildfire smoke seasons, non-combustibility and moisture stability aren't marketing points — they're the two things that matter most for long-term performance.
HZ5 Engineering for the Pacific Northwest
Hardie engineers its products by climate zone, and the HZ5 line is built for regions with freeze-thaw cycling and sustained moisture exposure — which describes most of Western Washington. That means the formulation and installation specs we follow are matched to what Skagit County actually throws at a house, not a generic national spec.
ColorPlus Factory Finish
Most of what fails on painted siding isn't the substrate — it's the finish. Field-applied paint on any siding material is only as good as the prep, primer, number of coats, and cure conditions on install day, and it will need repainting on a cycle. Hardie's ColorPlus finish is baked on in a controlled factory environment, with a finish warranty backing it. In a climate with a long wet, low-sun season where paint never quite gets ideal curing weather, that factory-controlled process is a real advantage, not a nice-to-have.
Warranty That Follows the House
Hardie backs its products with a strong, transferable limited warranty. That matters to homeowners in Skagit County who may sell within a decade or two — a transferable warranty is a selling point at closing, not just a file in a drawer.
Why We Don't Install the Alternatives
We're not going to tell you vinyl, LP SmartSide, or cedar are bad products in every application — plenty of homes around the country wear them fine. Our decision is about what we're willing to warranty our labor against, given our climate:
- Vinyl siding is affordable and low-maintenance, but it expands and contracts with temperature swings, can distort or crack in impact, and its appearance is fixed at manufacture — it can't be painted to refresh a look down the road.
- LP SmartSide is a wood-strand product with a solid track record when installation and caulking are perfect and maintained forever, but it's still wood-based, and wood-based products are less forgiving of the sustained moisture exposure common on the west side of the Cascades.
- Cedar and primed spruce are beautiful, but they require an ongoing maintenance commitment — refinishing, caulking, moss treatment — that most homeowners underestimate until year five or six.
- Cemplank and Allura are also fiber cement and share some of Hardie's core advantages, but we've standardized our crews, flashing details, and warranty process around one manufacturer's specifications so there's no ambiguity about what correct installation looks like on your house.
Installation Is Half the Product
Fiber cement performs the way it's rated to only when it's installed to spec — correct clearances off grade and roof lines, proper fastening, rain-screen or drainage plane details where called for, and factory-mitered or caulked joints done right. A lot of the siding problems we get called out to inspect in Skagit County trace back to installation shortcuts, not the material itself. Standardizing on one product lets our crews install the same way, every time, and know exactly what a warranty claim requires.
