Conway doesn't get talked about as much as Anacortes or Mount Vernon, but the homes there deal with a climate all their own. It's a low-lying community set down in the Skagit River valley, and that position changes how siding ages compared to a house up on higher, more open ground. We install siding throughout Skagit County, and Conway is one of the areas where we've learned to treat the valley setting as its own set of conditions rather than assuming what works on a bluff lot in Anacortes will automatically hold up the same way here.
Why Conway's Setting Matters for Siding
Conway sits low, close to the river and surrounding wetlands, which means fog and standing dampness linger longer here than they do on higher, wind-exposed ground. Where a coastal Anacortes property dries out faster because it catches steady wind off the water, a Conway property in a low valley pocket can stay damp for hours after everyone else's siding has already shed the morning moisture. That extra dwell time matters — it's the difference between water that sheets off a wall and water that has time to work its way into a seam, a nail hole, or a piece of trim that wasn't flashed correctly.
The same regional pattern that shapes the rest of Skagit County still applies here: driving rain through the wet season, a moss season that can run most of the year on shaded surfaces, and enough salt-tinged air moving in off Skagit Bay to matter over the life of a coating or a fastener, even a few miles inland. Add mature tree cover, which is common on Conway lots, and you get siding that spends more of the year shaded and damp than a comparable house in an open subdivision closer to town.
What We Typically Find on Older Conway Siding
- Moss and algae staining concentrated on north- and east-facing walls that don't get direct sun to dry them out
- Paint failure and graying on wood siding and trim from repeated wet-dry cycling without enough sun exposure to fully recover between rains
- Soft or spongy siding low on the wall, near grade, downspouts, or areas where splashback keeps the material wet longer than the rest of the house
- Caulking that's cracked or pulled away at butt joints and trim, letting water track behind the siding instead of running off it
- Fastener corrosion or staining bleeding through paint on older installations that weren't detailed for sustained damp exposure

What a Correct Siding Installation Actually Involves
Siding installation isn't just fastening boards to a wall — the boards are the visible part of a system that's mostly invisible once the job is done. On a Conway property, where the material is going to spend more time damp than it would elsewhere in the county, getting that hidden system right matters even more than usual.
A correct installation starts underneath the siding, not at it. That means a continuous, properly lapped water-resistive barrier, flashing at every window, door, and roof-to-wall intersection, and attention to details like kickout flashing where a roofline meets a sidewall — a spot that's a common source of hidden rot when it's skipped or done wrong. From there, fastening has to follow the manufacturer's schedule for nail placement, spacing, and penetration depth, and the siding itself needs the correct clearance off grade, roof surfaces, and decks so it isn't sitting in standing water or trapped moisture from day one.
On a shaded, damp lot, we also pay close attention to how the wall assembly dries. A rain screen gap — a small airspace between the siding and the water-resistive barrier — gives any moisture that does get past the cladding a path to drain and evaporate instead of sitting against the sheathing. That detail matters more on a Conway lot that stays damp longer than it does on a wall that gets steady sun and wind to dry it out on its own.
Installation Checklist We Follow on Every Job
- Full inspection and repair of sheathing before any new siding goes on — rot found late costs more than rot found early
- Continuous water-resistive barrier, properly lapped and taped at seams
- Flashing at every window, door, roof-wall intersection, and other penetration, including kickout flashing where needed
- Rain screen gap on shaded or moisture-prone walls to let the assembly dry
- Fastening to manufacturer spec — correct nail type, spacing, and penetration, not just "close enough"
- Proper ground, roof, and deck clearances so siding isn't sitting in standing water
- Sealed and primed cut ends, since an unsealed cut edge is one of the fastest ways fiber cement siding takes on water damage
Why We Install Only James Hardie Fiber Cement
We don't install vinyl, LP SmartSide, Cemplank, Allura, primed spruce, or cedar. That's a deliberate standard, not a marketing line, and it comes from watching how different products actually hold up in a Skagit County climate — a damp valley property like Conway is a good test case for why we settled where we did. Vinyl isn't a water barrier by itself; it depends entirely on what's behind it, and it can grow brittle with age and UV exposure. Wood needs a repainting cycle that's hard to keep up with when a wall stays damp for extended stretches, and once moisture gets behind wood siding or trim, rot follows. Fiber cement doesn't share those weaknesses — it's dimensionally stable, it doesn't rot the way wood does, and it holds up to sustained moisture exposure far better than a loose-hung plastic cladding.
James Hardie's ColorPlus finish is baked on at the factory and backed by its own fade and coating warranty, which matters on a shaded property where a field-applied paint job would otherwise need touching up more often. Hardie also builds climate-engineered HZ product lines specifically for wetter regions like ours, rather than selling the same generic formulation everywhere in the country. Combined with a strong transferable warranty, it's the product we're willing to install and stand behind on a Conway home, year after year, through a full wet season.
Hardie Product Lines We Install
| Product Line | Best For | Notes |
|---|---|---|
| HardiePlank Lap Siding | Most Conway homes, traditional and farmhouse-style exteriors | Smooth or cedar-textured finish, wide ColorPlus range |
| HardiePanel Vertical Siding | Gable ends, accent walls, outbuildings | Clean vertical lines, pairs with lap siding |
| HardieTrim Boards | Window and door surrounds, corners, fascia | Resists the swelling and rot that plague wood trim in damp shade |
| HZ5 Climate Engineered | Shaded, low-lying, or moisture-heavy lots | Formulated for wetter climate zones, including ours |
Our Installation Process for a Conway Home
The process itself doesn't change dramatically from house to house, but the sequencing and pace do, especially on a job that has to work around a valley property's longer damp stretches and shorter dry windows during the wet months.
- Inspection and scope. We walk the exterior, check current siding and trim condition, and note any signs of moisture damage, especially in shaded and low-lying areas of the wall.
- Removal and sheathing check. Old siding comes off and we inspect the sheathing underneath for soft spots or rot before anything new goes up — this is the point where hidden problems get caught and fixed instead of covered over.
- Weather barrier and flashing. A continuous water-resistive barrier goes on, followed by flashing at every window, door, and roof intersection, plus a rain screen gap where the wall's exposure calls for it.
- Hardie installation. Boards go up to manufacturer fastening spec, with correct clearances and cut ends sealed and primed as they're installed, not after the fact.
- Trim and finish work. Trim boards, corners, and caulking are finished out, keeping caulk-dependent joints to a minimum in favor of proper flashing and lap details wherever the design allows.
- Final walk-through. We go over the finished job together, point out anything worth knowing about future maintenance, and make sure everything meets the standard we'd want on our own house.
What Affects the Cost of a Conway Siding Job
Every siding job is priced around the specifics of the house, but a few factors come up consistently on Conway properties in particular.
| Cost Factor | Why It Matters |
|---|---|
| Sheathing condition | Rot found after tear-off adds repair work that can't be scoped until the old siding is off |
| Home size and wall complexity | More corners, dormers, and roof-wall intersections mean more flashing detail and labor time |
| Existing siding type | Removal and disposal effort varies significantly between old wood, vinyl, or a prior fiber cement job |
| Trim and accent work | Vertical panel accents, custom trim profiles, and detailed corners add material and install time |
| Site access | Long rural driveways, tree cover, and staging space on a Conway lot can affect equipment and material logistics |
| Color selection | Factory ColorPlus finishes vary in cost by color family compared to standard primed board |
Why a Crew That Already Works Conway Matters
Skagit County's microclimates aren't uniform, and a valley community like Conway behaves differently than the bluffs and open shoreline closer to Anacortes. Knowing that a low, tree-shaded lot is going to hold moisture longer, that certain wall orientations are going to grow moss no matter what finish goes on them, and that rural properties often mean longer access routes and more staging planning — that's knowledge built from working these properties repeatedly, not something you get from a general spec sheet. It shapes how we sequence a job, where we add extra flashing attention, and what we tell a homeowner to expect for drying time between install steps during the wetter months.
It also means fewer surprises during permitting and less guesswork about what a particular Conway lot is going to throw at a crew — septic and well setups, outbuildings, mature trees close to the house, and driveway access that a crew unfamiliar with the area might not plan for ahead of time.
