Anacortes Siding Why Old Town Anacortes Needs a Different Siding Approach
Old Town Anacortes sits close to the water on Fidalgo Island, which means the siding on these homes works harder than siding almost anywhere else in Skagit County. Salt-laden air off the channel, wind-driven rain that comes in sideways during winter storms, and long stretches of shaded, damp weather that feed moss growth all combine to break down the wrong materials faster than homeowners expect. A siding installation here isn't just a cosmetic upgrade — it's the building envelope that decides whether the walls behind it stay dry for the next thirty years.
We install siding across Anacortes and the surrounding area, and Old Town is one of the neighborhoods where getting the details right matters most. Many of these homes have older wall assemblies, a mix of past siding repairs, and exposure patterns shaped by mature trees and close-set lots. A generic siding job — the kind that treats every wall the same regardless of orientation or history — tends to fail here years before it should.
What the Marine Climate Actually Does to Siding
Salt Air and Slow Corrosion
Airborne salt doesn't just affect metal railings and hardware — it accelerates the breakdown of caulking, degrades lower-quality paint finishes, and speeds up corrosion on any fasteners or trim components that aren't rated for coastal exposure. Over years, this shows up as chalking, fading, and fastener staining well before a siding product's expected lifespan is up.
Wind-Driven Rain and Water Intrusion
Anacortes gets plenty of rain that doesn't fall straight down — it's pushed sideways by wind off the water. That matters enormously for siding, because most siding failures aren't caused by rain hitting the face of the wall; they're caused by rain finding its way behind the siding through poor flashing, gaps, or butt joints that were never properly sealed. A material that looks fine from the curb can be hiding rot in the sheathing behind it.
Moss Season and Prolonged Moisture
Shaded north- and west-facing walls in Old Town's more tree-covered lots can stay damp for weeks at a stretch during the fall and winter. That's exactly the environment moss and mildew need to take hold. On porous or wood-based siding, sustained moisture contact softens material over time; on the wrong products, it can lead to swelling, delamination, or structural decay at butt joints and bottom edges long before the siding shows obvious surface damage.
The Age and Character of Old Town Homes
Common Problems We Find
Because many homes in this neighborhood are older, we regularly find layered siding history: an original material, a past repair or two, and sometimes a full re-side that wasn't done to current standards. Typical issues include missing or corroded flashing above windows and doors, siding installed tight to grade with no clearance, caulk used as a substitute for proper flashing, and trim boards that were never back-primed or sealed on cut ends.
Working With Older Wall Assemblies
An older home's sheathing and framing may not match what's behind a wall built in the last fifteen years. That means a siding installer working in Old Town needs to actually open up the wall during tear-off, assess what's underneath, and address any rot, uneven framing, or outdated water-resistive barrier before new siding goes on — not just staple new material over old problems. This is where a lot of budget re-side jobs go wrong: covering up damage instead of fixing it first.
Why We Install Only James Hardie Fiber Cement
We made a deliberate decision to install one siding system — James Hardie fiber cement — and not vinyl, LP SmartSide, Cemplank, Allura, primed spruce, or cedar. That's not a marketing position; it's a standard we hold because of what we see in climates exactly like this one.
Non-Combustible and Climate-Engineered
James Hardie fiber cement is non-combustible, which matters for long-term insurance and safety considerations regardless of coastal exposure. Just as important for this region, Hardie engineers specific product formulations — its HZ5 line — for climates with significant moisture exposure, which describes the Pacific Northwest coast well. That engineering targets the exact failure mode we see most in Old Town: moisture cycling at the board itself, not just at the seams.
ColorPlus Factory Finish
Rather than relying on field-applied paint, Hardie's ColorPlus finish is baked on at the factory under controlled conditions, which gives far more consistent, UV- and fade-resistant coverage than paint applied on-site — especially valuable where salt air accelerates finish breakdown on lesser coatings.
Why Not the Alternatives
Vinyl siding is inexpensive and low-maintenance in mild conditions, but it can warp or crack in temperature swings, its seams and J-channels are a common water-entry point, and it doesn't offer the fire performance of fiber cement. LP SmartSide and other engineered wood products perform reasonably when installation and maintenance are followed precisely, but they're wood-based at the core — meaning any breach in the finish gives moisture a path to swell or rot the substrate, which is a real risk in a climate with this much sustained dampness. Cedar is a genuinely attractive natural material, but it demands ongoing refinishing and is vulnerable to moisture, insects, and rot without diligent upkeep — upkeep that's especially demanding in shaded, moss-prone areas. We'd rather install one product we trust completely than offer several and hope the homeowner maintains the riskier ones perfectly.
What a Correct Siding Installation Actually Involves
Water-Resistive Barrier and Flashing First
Before a single piece of siding goes up, the wall needs a continuous, correctly lapped water-resistive barrier and properly integrated flashing at every window, door, and penetration. Flashing has to shed water down and out — never trap it behind the cladding. This step is invisible once the job is finished, which is exactly why it's the step corners get cut on most often.
Fastening and Clearances
James Hardie specifies exact fastener types, spacing, and embedment depth, along with minimum clearances from grade, roofing, and decks. Skipping these specifications — for example, running siding too close to the ground, a common shortcut — invites the exact wicking and rot problems that a fiber cement product is otherwise built to resist.
Joints, Caulk, and Finish Details
Butt joints, corners, and trim transitions need to be treated with the manufacturer's specified sealants and techniques, not just caulked generically. On a coastal property, these small details determine whether the assembly sheds wind-driven rain or lets it collect at the weak points.
Our Process for Old Town Anacortes Projects
Assessment
We start by walking the exterior and, where needed, opening test areas to see what's actually happening behind the existing siding — not just what's visible on the surface. On homes near the water, we pay particular attention to shaded walls, low-clearance areas, and any spots showing past water staining.
Tear-Off and Prep
Old siding comes off, damaged sheathing or framing gets repaired, and a new water-resistive barrier and flashing system go in correctly around every opening. This is the phase that determines whether the finished job lasts fifteen years or fifty.
Installation and Final Inspection
James Hardie panels or planks go on to manufacturer specification, with attention to fastening, clearances, and joint treatment. We walk the finished job with the homeowner before calling it complete.
Comparing Siding Options for a Marine Climate
| Material | Moisture Resistance | Maintenance | Fire Performance | Typical Longevity |
|---|---|---|---|---|
| James Hardie Fiber Cement | Engineered for wet climates (HZ5) | Low — factory finish holds color | Non-combustible | Decades, installed to spec |
| Vinyl | Seams and channels are entry points | Low, but can't be repainted easily | Combustible, can deform in heat | Moderate, shorter in harsh exposure |
| LP SmartSide (engineered wood) | Vulnerable if finish is breached | Moderate — finish upkeep matters | Combustible | Good with strict maintenance |
| Cedar | Absorbs moisture without upkeep | High — regular refinishing needed | Combustible | Variable, maintenance-dependent |
What Homeowners Should Check Before Re-Siding
- Look for chalky, faded, or peeling paint on south- and west-facing walls first — these show sun and salt exposure fastest
- Check for soft spots, bubbling, or dark staining near the bottom few feet of any wall, especially near grade or decks
- Look for moss or persistent green staining on shaded walls, which signals prolonged moisture contact
- Inspect caulk lines at trim and windows for cracking or gaps — a common early sign of a failing water barrier
- Ask any contractor bidding the job whether they'll open the wall during tear-off or simply install over the old surface
- Confirm which siding product and finish system is being quoted, and whether it's rated for coastal or high-moisture climates
Why Local, Neighborhood-Specific Experience Matters
A siding crew that already understands Old Town Anacortes's mix of older homes, tight lots, and marine exposure will catch problems a generalist crew might miss — where flashing tends to fail first, which walls need extra attention because of shade and moss, and how to sequence a tear-off so a home isn't exposed to a sideways rainstorm mid-project. That local pattern recognition, paired with a single product line we install to the same standard on every job, is what keeps a siding installation from becoming a recurring repair.
