Siding Installation Built for Conway's Conditions
Conway sits low in the Skagit River delta, on open, flat farmland just inland from Skagit Bay. That geography matters more than most homeowners realize when it comes to siding. There's little in the way of hills or tree cover to break up wind coming off the water and across the fields, which means driving rain hits exterior walls harder and more often than it would on a more sheltered lot a few miles away. Add in the near-constant humidity that comes with sitting close to river bottomland, and you've got a recipe for siding that stays wet longer after every storm.
That combination — salt-tinged air, wind-driven rain, and a long moss season that can run from fall through spring — is exactly what wears out the wrong siding material or a poorly installed job in this part of Skagit County. A siding installation done right here isn't just about appearance. It's about managing moisture at every seam, joint, and fastener so the wall assembly behind the siding stays dry for decades, not just for the first few winters.

What Conway Homes Actually Need From Their Siding
Moisture Management Comes First
Any siding product can look fine in a showroom. The real test is what happens after ten winters of horizontal rain and a damp growing season that lets moss and algae get a foothold on north-facing walls and shaded elevations. In Conway, we see this show up as green-black streaking, soft trim boards, and paint that fails years ahead of schedule — almost always because water was getting behind the siding, not just landing on it.
Wind Exposure on Open Lots
Because so much of the land around Conway is open farmland, homes here often don't have the windbreak that a wooded lot or a tighter neighborhood provides. That means fastener schedules, panel overlaps, and trim details all need to be installed to hold up against wind-driven rain hitting the wall at an angle, not just rain falling straight down. Skipping or shortcutting these details is a common source of early failure.
Salt Air's Slow Effect on Metal and Finishes
Skagit Bay is close enough that salt-laden air reaches Conway on a regular basis. Salt air accelerates corrosion on exposed fasteners and lower-grade trim, and it breaks down cheap paint finishes faster than inland areas ever see. Siding and trim need corrosion-resistant fastening and a factory finish built to hold color and integrity in a marine-influenced climate, not just a coastal-adjacent one.
Why We Install Only James Hardie Fiber Cement
We don't install vinyl, LP SmartSide, primed wood, cedar, or other fiber cement brands. That's a deliberate standard, not a sales pitch, and it comes directly from what we've seen hold up — and what doesn't — in Skagit County's climate.
Vinyl can warp and gap as temperatures swing, and its seams give wind-driven rain an easy path behind the cladding. Wood and engineered wood products need consistent, disciplined maintenance to keep moisture out, and a long moss season here doesn't make that easier. Other fiber cement brands may perform reasonably well, but James Hardie is the one we've standardized on because of specific, verifiable advantages:
- Non-combustible fiber cement core that doesn't feed a fire the way wood-based products can
- ColorPlus factory-applied finish, baked on under controlled conditions rather than field-painted, which holds up better against UV and salt air over time
- HZ10 product engineering, developed specifically for the Pacific Northwest's wet climate, addressing moisture and freeze-thaw behavior rather than a generic national formulation
- A strong, transferable manufacturer warranty backed by a company with decades in the fiber cement business
- Proven long-term performance in similar wet, wind-exposed marine climates up and down the coast
None of this means other products are junk — it means that after years of installing and repairing siding in this specific climate, Hardie is what we're willing to put our name behind.
What a Correct Siding Installation Involves
The siding itself is only part of the system. A correct installation is really about everything that happens before the first plank goes up.
Sheathing and Substrate Check
Before anything new goes on, we check the existing sheathing for rot, soft spots, and old water damage — especially common on homes that have gone years with a failing weather barrier or damaged siding. Any compromised sheathing gets addressed before we move forward. Installing new siding over a wet or rotten wall assembly just hides the problem.
Weather-Resistive Barrier and Drainage Plane
A properly lapped weather-resistive barrier goes on first, followed by a drainage gap that lets any moisture that does get behind the siding drain and dry out instead of sitting against the wall. This is one of the details that separates a durable installation from one that looks fine for a few years and then starts showing problems.
Flashing at Every Penetration
Windows, doors, hose bibs, vents, and any other wall penetration need proper flashing integrated with the weather barrier. In a climate that gets as much driving rain as Conway does, flashing mistakes are one of the most common sources of hidden water damage.
Fastening and Clearances to Spec
James Hardie has specific fastening requirements and minimum clearances from grade, roof lines, and decks. Following these to the letter — not just approximately — is what keeps the manufacturer's warranty valid and keeps water from wicking into the bottom edge of the siding.
Our Installation Process
- On-site assessment: we inspect your current siding, trim, and visible sheathing condition, and talk through what we find
- Tear-off: removal of old siding and trim, with sheathing repairs where needed
- Weather barrier and drainage plane installation
- Flashing at windows, doors, and all penetrations
- Hardie panel and trim installation to manufacturer fastening and clearance specifications
- Caulking and final detailing at joints and transitions
- Walkthrough so you understand what was done and what to expect from the finish over time
Cost Factors to Understand Before You Budget
| Factor | Why It Affects Your Project |
|---|---|
| Sheathing condition | Rot or water damage found during tear-off requires repair before new siding goes on |
| Home size and wall complexity | More corners, gables, and trim detail means more labor and material |
| Siding profile and color | ColorPlus finishes and certain profiles vary in material cost |
| Site access | Open, flat lots are often easier to stage than tight or sloped sites, which can affect labor time |
| Trim and detail work | Window and door trim, fascia, and corner detail add cost beyond flat wall area |
We won't quote a number without seeing the house, but we're glad to walk you through where your money is actually going once we have.
Common Problems We See on Older Conway Siding
A lot of the calls we get in this area aren't about wanting a new look — they're about problems that have been building quietly for years. Moss and algae staining on shaded or north-facing walls is one of the most common, often a sign that a surface is staying damp longer than it should. Soft or spongy trim boards, paint that's failed well ahead of schedule, and gaps at panel seams where wind-driven rain has found a way in are all patterns we see repeatedly on homes that were sided with lower-grade materials or without proper drainage detailing.
None of these are unusual for the climate — they're predictable outcomes when a wall assembly isn't built to manage the moisture load Skagit County puts on it.
Caring for Your Siding After Installation
- Rinse siding annually to keep moss and algae from establishing on shaded walls
- Keep gutters clear so overflow isn't running down the wall face
- Trim back vegetation that keeps siding shaded and damp
- Check caulking at trim joints every couple of years and touch up as needed
- Address any soft trim or staining early rather than waiting for it to spread
Hardie's ColorPlus finish is low-maintenance, but "low-maintenance" doesn't mean "no maintenance" — a few minutes of attention a couple times a year goes a long way in this climate.
Why a Crew That Already Works in Conway Matters
Siding crews that mostly work drier, more sheltered inland areas don't always account for what open, low-lying Skagit County land does to a wall assembly. We work this specific region regularly, which means we're not guessing at flashing details or fastening schedules — we're applying what we've already seen hold up, and what we've already seen fail, on homes with the same exposure yours has. That familiarity with local conditions, plus knowing how Skagit County permitting and inspection works, means fewer surprises during your project.
